This research primarily focuses on the interactions between transition metal complexes and DNA. This work aims at understanding the principles of DNA recognition, with the ultimate goal of being able to design compounds that can control gene expression - the next great target now that most of the human genome has been sequenced. We study the interactions of inert dinuclear ruthenium complexes with DNA and RNA. Dinuclear ruthenium complexes, rather than the more often studied mononuclear complexes, offer many advantages. Dinuclear complexes bind selectively at DNA and RNA non-duplex sites, e.g. bulges and hairpin-loops, where shape, size, functionality and charge govern selectivity and affinity.

In addition, we are also involved in the development of a new, and very promising, class of anti-cancer drug – multinuclear platinum complexes. We design and synthesise new complexes, determine their biological activity and examine their binding to DNA by NMR spectroscopy. In addition, we are exploring the possibility of reducing the toxicity and degradation by plasma proteins of multinuclear platinum complexes by encapsulating them in cucurbituril, an open-ended barrel shaped host molecule.

Recent ResearchAssoc. Prof. Grant CollinsOver the last decade there has been considerable interest in DNA secondary structures that deviate from the well-known double helix. One example is a bulge structure in which there are regions of the duplex possessing one or more unpaired bases. These structural motifs are often associated with important biological functions: DNA bulge sites can be created during recombination between imperfectly homologous sequences, and are thought to play an important role in frame-shift mutagenesis. More recently, bulge sites have been shown to bind some DNA-repair proteins more tightly than duplex DNA and consequently are potential binding sites for therapeutic agents. Given their biological importance and potential as a target for novel drugs, there has been considerable research aimed at developing small molecules that can selectively target DNA bulge sites.

In collaboration with Prof. R. Keene (JCU) we have shown that non-intercalating, rigid, dinuclear ruthenium complexes associate weakly with the minor groove of duplex DNA; importantly however, these complexes demonstrate a much greater affinity for more open and/or flexible secondary structures such as bulge sites.

Multinuclear platinum complexes, developed by Farrell and coworkers, have shown considerable promise as anti-cancer agents. Unlike cisplatin, di- and trinuclear platinum complexes, where two or three platinum coordination centres are linked by diamine chains, form flexible long-range interstrand DNA adducts. It is from this novel DNA binding mode that multinuclear platinum complexes are thought to derive a different cytotoxic profile to cisplatin. Pre-clinical studies demonstrated that the multinuclear platinum complexes were considerably more active than cisplatin in a range of cell lines, and more importantly, maintained their activity in the corresponding cisplatin resistant cell lines. While multinuclear platinum complexes are highly cytotoxic, they have a

relatively narrow therapeutic index. Phase I clinical trials indicated that the Maximum Tolerated Dose (MTD) for the trinuclear complex BBR3464 was much lower than platinum drugs already in the clinic. Furthermore, most of the platinum drug binds thiol containing plasma proteins in the bloodstream, and is subsequently degraded to nonactive metabolites. Consequently, methods that can reduce the toxicity and/or decrease the binding of thiol containing proteins could improve the clinical utility of multinuclear platinum drugs. We have demonstrated that encapsulation of the multinuclear platinum complexes within the cavity of a cucurbituril overcomes the problems associated with plasma protein binding, and hence, may represent a new drug delivery technique for this class of anti-cancer compound.

Student ResearchAnalysis of DNA binding of Pixantrone

Najia Adnan ([email protected]) MastersField of Study: Biological Chemistry

The reversible DNA-binding of pixantrone and its activated reactive form should be identical, as the binding is due to the intercalculation of the non-reactive planar polycyclic aromatic part of the drug. Consequently, we propose to examine the binding of pixantrone to a range of small segments of DNA (oligonucleotides) by nuclear magnetic resonance (NMR) spectroscopy. In order to compare the DNA-binding of pixantrone to other anthracyclines, initial NMR experiments will utilize a particular well-characterised oligonucleotide. Then, in conjunction with molecular modelling, a detailed picture of the reversible binding will be developed. In the second phase of the research, the reversible binding of pixantrone will be screened against a wide range of oligonucleotides that contain different base sequences and structures (such as base-bulges), using fluorescence intercalator displacement assays. Those sequences or structures that show the strongest pixantrone binding will then be used in subsequent NMR experiments.

Dinuclear ruthenium complexes as therapeutic agents

Cucurbit[n]uril- a delivery host for anti-cancer drugs

Yunjie Zhao ([email protected]) PhDField of Study: Biological Chemistry

Multinuclear platinum complexes and the organic drug albendazole offer real potential for the treatment of cancer. However, and as with many other anti-cancer agents, their clinical use is limited by pharmacological problems. The potential of a relatively new class of macrocyclic host molecules, called cucurbit[n]uril (Q[n]), to act as a delivery system for these drugs and overcome the clinical drawbacks has been investigated. In order to examine particular aspects of the cucubit[n]uril binding of the drugs, new multinuclear platinum complexes and

benzimidazole carbamate derivatives have been synthesized, and their biological activity compared to the parent compounds.

Dinuclear ruthenium (II) complexes as DNA-binding drugs

Michele Pisani ([email protected]) MastersField of Study: Biological Chemistry

Dinuclear ruthenium (II) complexes preferentially bind non-duplex DNA and RNA sites. Consequently, these compounds have significant potential as therapeutic agents. In this study the binding of the dinuclear ruthenium complexes to DNA/RNA and various drug delivery agents (dendrimers and cucurbiturils) is being examined.

Supramolecular chemistry

Linta Chalissery ([email protected]) MastersField of Study: Biological Chemistry

Developing analytical techniques for the purification of “cucurbiturils”, a molecular host and a drug delivery vehicle. Available methods to purify cucurbiturils are inefficient and time-consuming. We are developing a method based on column chromatography that is much easier to implement in large scale.

PhD Opportunities and ScholarshipsThere are PhD and Masters opportunities in all the research areas described above.

NMR spectroscopy is the central tool of experimental chemistry. It is used to determine the structure and shape of molecules, which, in turn, determine physical properties, and chemical and biological activity. NMR spectroscopy can also be used to follow reaction kinetics at the atomic level, establish the nature of interactions between two or more molecular species, and study diffusion of dissolved compounds.

School of Physical, Environmental and Mathematical Sciences - Research Report 09/1008

Laser SpectroscopyElectronic transitions in solids are inhomogeneously broadened through the variation of local fields: each optical centre has a different local environment, even in well defined single crystals, due to imperfections and isotope distributions. The energy of an electronic transition depends on the local field, and thus varies over a range reflecting its distribution. Typical inhomogeneous widths of excitations in crystals are of the order of magnitude of 30 GHz (=1 cm-1) respectively, whereas the homogeneous width can approach the limit imposed by the excited state lifetime and be as narrow as 100 Hz (=3x10-9 cm-1) at liquid helium temperatures.

laser based techniques such as spectral hole-burning, fluorescence line narrowing and coherent transient spectroscopy, can overcome the inhomogeneous broadening and extremely narrow features can be measured. The main goal of the laser Spectroscopy research group is to apply laser based techniques to chemically interesting system, including X-ray storage phosphors, nanoparticles and transition metal ions at extreme dilutions. Besides of delivering valuable results for a better understanding of electronic structure in the solid state, the prevailing driving force behind these spectroscopic studies are the potential applications in data storage and signal processing. Although conventional semiconductor based electronics and magnetic storage are the dominating technologies today, the ever increasing demands for high capacity, high speed storage and processing warrants investigations into optical computing and optical data storage. We are convinced that conventional technologies will be superseded by all-optical technology over the next decades.

Current ResearchHans Riesen and his team are interested in a wide range of problems, ranging from applied research, such as X-ray storage phosphors, to very fundamental problems such as coherent transients, and “slow and stopped light” in transition metal doped systems.

The group has currently three major thrusts:

• The full development of the samarium based X-ray storage phosphors which have a significant chance to replace current personal radiation monitoring systems worldwide. UNSW has a spin-off company, Dosimetry & Imaging Pty ltd, that commercializes this development. The technology can also be used for real time monitoring of doses administered in radiation therapy, and in medical imaging such as dental X-ray diagnostics and mammography. In particular for the latter, there is an urgent need to reduce X-ray dose.

• Optical and electronic properties of transition metal doped wide bandgap semiconductors are investigated by modern laser spectroscopy and a range of synchrotron based techniques such as XANES and XAFS. Some of the investigated materials have significant potential for applications in photovoltaic and electroluminescent devices.

Laser Spectroscopy• We are continuing our quest in very high resolution laser

spectroscopy of transition metal ions in the solid state. In particular we are pursuing frequency-switched coherent transients and slow light effects in hole-burning media.

Research HighlightAssociate Professor Hans Riesen has had a study of spectral hole burning selected as an Editor’s Choice paper for publication in Chemical Physics Letters. The paper is titled ‘Transient spectral hole-burning studies of the R2 line in ruby’. The paper’s authors are Hans Riesen, Nicolas Riesen; Nathan Schubert and Alex Szabo. Nicolas Riesen was a visiting Fellow in the School of PEMS from December 2007 to January 2008; Nathan Schubert was a CDF student who graduated in 2008 from UNSW@ ADFA; and Alex Szabo is the originator of high resolution spectroscopy of the solid state.

Recent Achievements/Recent ResearchHans Riesen, Stewart Campbell and Dr Gordon Kearley (ANSTO) were awarded a total of 16 days of beamtime on two instruments at the Berlin Neutron Scattering Centre (BENSC). Their projects were entitled: “Spectral Hole-Burning - Neutron spin-echo studies of water flips in NaMgAl(oxalate)3·9H2O” and “Structure of NaMgAl(oxalate)3·9H2O - an extraordinary spectral hole-burning host”. Stewart and Gordon Kearley travelled to Berlin in October 2008 to conduct the experiments.

These experiments will shed light on an interesting phenomenon discovered in PEMS by Joe Hughes and Hans Riesen: partial deuteration of NaMgAl(oxalate)3·9H2O/Cr(III) yields a 1000-fold increase in the quantum efficiency of spectral hole-burning in an electronic transition of chromium(III).

Zhiqiang liu, PhD student operating the power X-ray diffraction beamline at the Australian Synchrotron, Melbourne.

PhD student Zhiqiang Liu, who is supervised by Hans Riesen, was selected to represent UNSW at the inaugural Australian Synchrotron Winter School. The inaugural Australian Synchrotron Science Winter

School held from the 13-16 July, 2009 is a comprehensive 4 day program which has been developed with the aim of building knowledge of synchrotron techniques and providing hands-on practical experience for young researchers. The programme held at the Australian Synchrotron allowed hands-on beamline experiments together with a structured set of lectures by leading experts in the field. Students were guided through the process of data collection by experienced beamline scientists, and learnt about sample mounting, data acquisition and interpretation of the results.

Hans Riesen, Tracy Massil and Zhiqiang Liu have also recently carried out some Powder X-ray Diffraction studies at the Australian Synchrotron in Melbourne. Access to beam time is awarded on a competitive basis. Hans and his co-workers were very impressed by both the quality of the facilities and their organisation.

Student ResearchOptical properties of transition metal ions in nanocrystalline wide-band gap semiconductors

Baran Yildirim ([email protected]) PhDField of Study: Photonics

In general, the aim of the study is to understand the optical and electronic properties of transition metal ions in wide-band gap semiconductors as a function of crystallite size. We started to examine some optical properties of Co2+ ions in liGa5O8 nanocrystalline powders; there are both octahedral and tetrahedral sites in this lattice. It is assumed that the Co2+ ions can enter the crystal lattice in both sites during the combustion reaction. In order to validate this and understand the charge transfer mechanism, spectral hole-burning studies were performed in nano-powders and single crystals. The nanocrystals are to be examined in different hosts such as glasses and glass ceramics. Additionally, XANES (X-Ray Absorption Near Edge Structure) and XAFS (X-Ray Absorption Fine Structure) measurements are to be done at the Australian Synchroton in order to quantify the Co2+ ions in tetrahedral and octahedral sites. This material has some potential for photovoltaic applications; one of our motivations for this research project. We will continue conducting a systematic study of the optical properties of a range of transition metal ions incorporated into oxide nanocrystals.

Spectroscopy of Samarium(III) activated x-ray storage phosphors

Zhiqiang Liu ([email protected]) PhDField of Study: Chemistry

My research is based on a recent invention of a highly efficient samarium(III) activated X-ray storage phosphor by Hans Riesen and his team. This phosphor has many applications in medical X-ray imaging and radiology, potentially reducing the harmful X-ray dose for patients. It can also be used in personal radiation monitoring. In contrast to current commercial X-ray storage phosphors, the samarium (III) activated phosphor allows an accumulative and repetitive readout of the X-ray exposure by very narrow f-f photoexcited luminescence. My project will mainly focus on detailed investigations of the storage mechanism of the samarium(III) activated phosphor by a range of modern techniques such as laser spectroscopy (spectral hole-burning and fluorescence line narrowing), scanning and transmission electron microscopy,

synchrotron powder diffraction and X-ray absorption experiments. Conventional spectroscopy techniques such as fluorescence, reflection, and Raman and ESR will also be employed in the project. Ultimately, we hope to gain a full understanding of the storage mechanism which may enable the design of other samarium(III) activated materials with even higher storage efficiencies.

PhD Opportunities and ScholarshipsPossible PhD projects include:

• Systematic studies of dephasing processes and host-guest interactions in transition metal and rare earth compounds. In order to gain a better understanding of the dependence of dephasing processes on the structural properties of the guest and the host, the temperature dependence of the homogeneous linewidth of transition metal and rare earth complexes will be studied in a range of hosts

• Optically detected NMR in coordination compounds. This project has a significant potential to overcome the shortcomings of conventional NMR spectroscopy of coordination compounds with paramagnetic centres.

• Optimising the properties of novel X-rays storage phosphors. This project would take advantage of our recent discovery of a highly effective X-ray storage phosphor.

Dr Lynne Wallace & Dr Anthony Day

NTO (nitrotriazolone) is a new insensitive explosive that may replace RDX, the current military standard, in some applications. Due to its high water solubility, the wastewater from its manufacture cannot be treated by conventional means. We have been investigating alternative remediation methods based on electrochemical treatment for NTO, which may also be applicable for other organic explosives. These electrochemical methods are more environmentally friendly, since no additional chemical loading is required, and the only input is electricity.

Synthesis and characterization of new high nitrogen compounds

Dr Lynne Wallace, Dr Anthony Day, Dr Arthur Provatas

Insensitive high explosives (IHEs) are an important area of research, due to the increased requirement for safer energetic materials in industrial and defence sectors. Azoxytriazolone (AZTO) is a new chemical species discovered by our research group, and preliminary results indicate it may possess potential as a new IHE. We are studying methods of synthesis of AZTO and other related compounds, and also investigating their solid-state and solution properties.

Synthesis and study of new iridium complexes for use in supramolecular and medicinal applications

Dr Lynne Wallace

Many molecular devices and pharmaceuticals contain components based on transition metals such as iridium or platinum. These transition metal complexes, consisting of organic units bonded to a central metal atom, can be structurally modified to fulfill different purposes. In this project, different synthetic approaches are used to prepare new iridium complexes, and these are studied, using a range of spectroscopic and electrochemical techniques, for their potential in light-activated molecular devices and to determine their interaction with biomolecules.

Synthesis, study and characterization of mono- and di- nuclear cobalt complexes to isolate metallo rotaxanes (a mechanically interlocked metalo architectures)

Rotaxanes are of interest for their potential use as molecular switch, nano-shuttles, molecular electronics and molecular muscles. Transition metal complexes as stoppers also offer the possibility for synthesis of metallo polyrotaxane. Moreover, having a transition metal within this supramolecular architecture furnishes it with specific photonic, electric and magnetic properties.

Student ResearchDetection of peroxide based explosives

Kirsten Randle ([email protected]) PhD Field of Study: Forensic Science/Counter Terrorism

Improvised explosive devices created from peroxide containing materials have increasingly been utilised in recent years by a number of terrorist organizations, particularly in Israel, as well as in the UK and the USA. Peroxide-based explosives can be easily “home-made” using inexpensive, readily available starting materials which can be obtained in most hardware stores. My aim is to develop a sensitive and reliable field test for the detection of these peroxide based explosives and others as Tri-Acetone Tri-Peroxide (TATP) and HexaMethylene Triperoxide Diamine (HMTD). This research focuses on the development of an enhanced visual detection kit using sensitive metal catalysts in conjunction with the ABTS + radical cation and organic colour changing reagent Syringaldazine (SyAZ) in addition to the family of molecules know as cucurbit[n]uril (n=6-10), which have the potential to enhance visual detection.

Current Research

Infrared digital cameras and olfactory attractants for monitoring wildlife

Dr David Paull & Dr Andrew Claridge

This project aims to develop a humane and cost-effective method for detecting rare and threatened wildlife. In biogeography, one great problem lies in obtaining reliable field data on the distribution of animals that are of conservation concern. In south-eastern Australia this is particularly the case for small mammals such as bandicoots and rat kangaroos. Traditional methods used to detect these species are trapping and hair tubing, which are distressing to the captured individuals, costly in terms of labour, or simply ineffective when populations exist in low density. Therefore, alternative approaches are needed. The aim of our research is to determine whether automated digital surveillance cameras are a viable option for detecting small mammals in south-eastern Australia. The methodology involves deploying digital infrared cameras across large areas of habitat in south-eastern Australia to determine the distribution of species of small mammals such as the southern brown bandicoot. We use small quantities of scent attractant, for example truffle oil, in front of each camera to encourage animals to enter the field of view and ‘pose’ while photographs are automatically taken. This research is greatly improving the tool kit we currently have for detecting elusive animals in the wild.

Funded by an ADFA Special Research Grant, David Paull and visiting fellow Andrew Claridge (NSW Dept of Environment and Climate Change) have been investigating the use of infrared surveillance cameras and olfactory attractants for detecting rare and endangered mammals. Traditional wildlife survey methods have normally relied on cage traps and baits like peanut butter, but the results have never been good. It is surprising that practically no research has been conducted on optimal bait types for detecting rare species. Media reports have highlighted David and Andrew’s exciting results with black truffle oil, which has attracted a range of threatened fauna including the nationally endangered southern brown bandicoot. ‘Bush truffles’ are an important part of the bandicoot’s natural diet, so perhaps it is not too surprising that the famous French Black Truffle (Tuber melanosporum ) also captures their attention. Truffle oil can

be obtained readily from quality delicatessens, whereas bush truffles are hard to find in useable quantities, even for experienced wildlife researchers. David and Andrew are now in close discussion with the Australian Truffle Growers Association with the aim of developing further research collaborations.

The southern brown bandicoot in south-eastern Australia: Its distribution, habitat use and conservation

Dr David Paull, Dr Andrew Claridge, Dr Michael Rees

The objective of this long-term project is to locate and map all remaining populations of the southern brown bandicoot Isoodon obesulus in south eastern Australia. Commencing in 1986, extensive field investigations for this rare marsupial have been ongoing in South Australia, victoria and New South Wales, with much of the historical distribution already having been surveyed. At sites where the species has been found, detailed habitat descriptions are made of vegetation, soils, climate and topography. This information is compiled as a baseline against which future changes to the species’ distribution and habitat can be measured. The data are also used for predictive spatial modeling using Geographical Information Systems to uncover new areas of potential habitat and estimate the extent of the species’ former distribution circa 1788. The research has been playing a vital role in the development of conservation plans. One outcome of the work to date has been a successful nomination by the principal investigator to have the species listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999.

He has an ongoing interest in achieving the transition of research into action. He is also drawing on his experience in monitoring and evaluation to coauthor a paper on the triple bottom line analysis of impact of investing in research in natural resource management. Tracking research impact and learning how to improve the outcomes of science investment is fundamental to environmental science’s multidisciplinary and integrated approach to significant issues.

Long-term coastal monitoring project

Jiashu Shen and Emeritus Professor Roger McLean

A long-term coastal monitoring project on beach morphology, sediment transport and underground water level at Moruya, NSW has been carried out in the last three decades. Foredune, beach and surfzone profile surveys have provided the landform change and sand volume variation along this sandy coastline since 1972. This data have been analysed together with the climate, wave, sea level and underground water level data and the preliminary results shows coastal accretion and erosion are closely related to the wave regime, sea level and underground water level fluctuation, and rainfall along this part of the coast. This research will help us to understand the coastal processes which are responsible for modifying the coastal landforms.

Dr Jiashu Shen and Jack Doyle conducting a beach survey at Moruya in June-July 2007. The seaward scarp was cut by high waves during those months, the vegetated scarp behind is a relic of the 1996 erosional event, and that in the extreme right is the result of the 1974 May-June storms, which were the most devastating along the NSW coast in the last 50 years.

Recent AchievementsAndrew Claridge (PEMS visitor and colleague of Dave Paull) “recently played a leading role in one of Australia’s biggest temperature forest fire research programs, studying the recovery of native plants and animals after fire in Ben Boyd National Park on the NSW southeast coast. last winter, parks staff conducted a prescribed burn across 1900 ha of the park, after a 12-year research program led by Claridge showed populations of southern brown bandicoots, long-nosed bandicoots and long-nosed potoroos were in decline.” A survey showed that a loss of habitat contributed to the decline in population numbers. The understory plants such as banksias, hakeas and acacias need fire to regenerate. Claridge spent months of careful planning to map and design the prescribed burn which, if well managed, “can be used successfully to regenerate habitat and revive declining populations”.

Roger McLean attended the IPCC scoping meeting on Extreme Events and Disasters: Managing the Risks which was held in Oslo, Norway. IPCC Working Group II (Impacts, vulnerability and Adaptation) organized the meeting and the Norwegian Pollution Control Authority provided significant support as well as the venue.

Seventy countries and fifteen observer organizations such as the International Red Cross nominated about 375 experts as meeting participants, including 115 nominated experts from developing countries and countries with economies in transition. The three communities whose expertise was needed to scope a possible Special Report: climate scientists, experts on the impacts of climate change and adaptation policies to address extreme events and extreme impacts, and experts on disaster risk reduction. These communities are reflected in the four Australians who attended the meeting: Acting Director of the Bureau of Meteorology (Neville Smith); Director-General of Emergency Management Australia (Tony Pearce); climate scientist (Neville Nicholls, Monash University) and Roger McLean (UNSW@ADFA).

Only fifteen presentations were given at the meeting. Roger McLean’s presentation was titled: Impacts of Weather, Climate and Sea level-Related Extremes on Coastal Systems and Low-Lying Islands, and dealt primarily with reporting our research results from the atoll island states of the Maldives in the Indian Ocean and Tuvalu in the Pacific.

Student ResearchAn assessment of recent changes in catchment sediment sources and sinks, central Queensland, Australia.

Andrew Hughes ([email protected])Field of Study: Geography (Fluvial Geomorphology)

Spatial and temporal information on catchment sediment sources and sinks can provide an improved understanding of catchment response to human-induced disturbances. This information is essential for the implementation of well-targeted catchment-management decisions. This study investigated the nature and timing of catchment response to human activities by examining changes in sediment sources and sinks in a dry-tropical subcatchment of the Great Barrier Reef (GBR) catchment area, in northeastern Australia. Changes in catchment sediment sources, both in terms of spatial provenance and erosion type, were determined using sediment tracing techniques. Optically stimulated luminescence and caesium-137 dating were used to determine pre-and post- European settlement (ca. 1850) alluvial sedimentation rates. The spatially distributed erosion/sediment yield model SedNet was applied, both with generic input parameters and locally-derived data. Outputs were evaluated against available empirically-derived data.

Climatic changes as the cause behind cessation in beach progradation throughout the late Holocene

Elspeth Rae ([email protected]) PhDField of Study: Coastal Geomorphology

Previous studies have shown several breaks in progradation along Bengello Beach ridge plain, southeast NSW. Using ground penetrating radar, thermoluminescent dating, and detailed sedimentary, topographic, and vegetation surveys, the cause of these breaks is being investigated. To validate methods, the results for the Holocene sequence are cross-referenced with time-series topographic survey data of the present day beach, dating back to the early 1970s. Preliminary results indicate climatic shifts analogous to those recently proposed across Eastern Australia.

The development of the Princess Charlotte Bay chenier plain

Dylan Horne ([email protected]) PhDField of Study: Coastal Geomorphology

Chenier plains record changes in the mode of coastal progradation between periods of mudflat progradation, and periods of beach ridge formation. There are potentially a number of environmental force(s) responsible for controlling these changes. A history of chenier research worldwide has led to a great understanding of these force(s) in some settings. In Australia however, despite a long history of chenier research the causes of these changes are still not well understood. Several conflicting theories have been proposed in the past to explain the evolution of a chenier plain in Princess Charlotte Bay on the eastern coast of northern Queensland, Australia. These include climate fluctuations, variations in shellfish populations, and storm activity. Since these were introduced, both methods and understanding of Holocene environmental processes have been improved. Improvements to methods include the replacement of radiocarbon dating with thermoluminescence techniques. Improvements to knowledge include a new body of research regarding the existence of (minor) sea level oscillations following the (major) transgression that occurred ~6000 B.P. These have allowed a reexamination of the mode of evolution of the Princess Charlotte Bay chenier plain. Some cheniers in the bay appear to have formed up to ~400K B.P., meaning the plain may have recorded changes occurring over several glacial cycles. Although the dating error associated with such old cheniers would be too large to link to known processes, a Holocene sequence is being examined and appears to be linked to sea level oscillations.

The effect of climate change on Mountain Pygmy-possum

Haijing Shi ([email protected]) PhDField of Study: Biogeography

My research focuses on a study of the microclimate and thermal properties of a range of the boulderfield habitats that support the endangered Mountain Pygmy-possum. Boulderfield sites across the range of Mountain pygmy-possum distribution will be monitored. The data loggers will be positioned in various areas of the habitat to collect thermal data from below the boulders at standardized depths, and one to be positioned above the general area of habitat to monitor air temperature. A camera recorder placed at each site will record the presence and depth of snow.

This study proposes to investigate: (1) the thermal properties of boulderfield habitats in relation to aspect, elevation and snow cover that support the endangered Mountain Pygmy-possum; (2) the snow cover and snow duration, to what extent, bring thermal stress to Mountain Pygmy-possum and (3) predicting range shifts in Mountain Pygmy-possum distributions and identification of refugia with ongoing climate change.

Sea level rise and human vulnerability: Developing a systems approach and perspective

Vijai Joseph ([email protected]) PhDField of Study: Geography

Across the globe, the water level of the sea was on the rise last century. This research aims at assessing the vulnerability of different occupational groups such as traditional fishermen, brackish pond farmers and industrial labourers to the phenomenon of sea level rise, taking tidal floods as a proxy for the impending hazard. This research tries to holistically analyze the livelihood-Environment Systems of these occupational groups and the mutual interplay between factors in this system that influence the vulnerability of the people to sea level rise through a System Dynamics approach. The comprehensive understanding of the nature of the livelihood-Environment Systems of these groups will be helpful to model the system behaviour determining the vulnerability status of these groups in different socio-economic scenarios. This kind of comprehensive understanding of the livelihood-Environment Systems and the interplay of the influential factors will help planners to plug holes in the system in order to adopt an efficient adaptive capacity improvement mechanism for the people to combat disasters like sea level rise. The whole exercise is contextualized on the coastal inundation model developed for different sea level rise scenarios using Geo-information tools and integration of this model with the System Dynamics model, which depicts vulnerability, is also part of the research aims.

Geographic Information Science is the study of the fundamental principles of geographic information and what makes geographic information different from other types of information. It is an interdisciplinary field, composed of researchers from geography, information science, cognitive psychology, mathematics, engineering, surveying, computer science, statistics and philosophy. Its focus is on theoretical advances in the handling, representation and communication of geographic information rather than on individual applications of geographic technologies (e.g., GPS, GIS and Remote Sensing). Within PEMS, our focus is on the representation and communication of geographic information, although several individuals in School of Engineering and Information Technology (SEIT) work on problems of data handling. Research in our group includes topics ranging from radar remote sensing of large mining projects in the Asia Pacific Region to evaluating the effects of data quality and error propagation on spatial analysis to understanding perceptual and cognitive factors that influence whether or not map readers see moving clusters in animated maps.

Current ResearchClusters on the move (with Sara Fabrikant):

Dr Amy L. GriffinOne of my current research projects is investigating the process of visual cluster detection in animated and static maps. In this research, we are examining the effectiveness and efficiency of different visual representations for seeing clusters that move through space and over time. We do this through experimental work with map readers, using methods such as behavioral analysis and eye-tracking. We have also explored the use of signal detection theory for describing map readers’ success rates in correctly identifying moving clusters. In late 2007, I collected eye-movement data while working with Sara Fabrikant at the University of Zurich in Switzerland. We have also recently acquired an eye-tracker in the School of PEMS at UNSW-ADFA.

‘Are Google and Web 2.0 making us stupid?’: Spatial information synthesis in a data-rich age

Dr Amy L. Griffin (with Anthony Robinson)The Internet has changed the way many people work. Instead of having too little information, our problem is now sorting through, evaluating the reliability of and integrating a surplus of information into a coherent understanding of ‘the big picture’. Many professions, including intelligence analysis, emergency response and policy development require workers to integrate spatial information to solve important problems. Our research examines the impact of interactive digital technologies on how well we integrate geographic information and will produce guidelines for developing computer tools and strategies that information workers can use to more accurately and efficiently bring together information from multiple sources and formats.

This research aims to understand whether and how using interactive digital spatial technologies alters our thinking habits and capacities. Specifically, we investigate spatial information synthesis – the integration of spatial information from multiple, messy sources to develop a coherent story about a problem. This information integration task (synthesis) - the ability to see ‘the big picture’ - is important in professions as diverse as emergency response, intelligence analysis and policy development and its results are often the basis for important decisions. Knowledge of the effects of technology on our thinking habits will enable the development of more effective computer tools and training materials to better support this capability.

Geographical analysis and environmental modelling; Geocomputation; Coastal geomorphology; the application of geographical analysis and environmental modelling, GISc and remote sensing to managing global change

Professor Brian LeesProfessor Lees and his students maintain an active research program focused on aspects of Global Change.

The first phase was the construction of a database of geomorphic evidence for past climate change across northern Australia. Most of this information has been published. A comprehensive review and re-assessment of this work is in preparation together with a reassessment of the implications of chenier dates in Northern Australia.

The second phase arose from the initial International Global-Biosphere Program (IGBP) meetings where it was clear that a great number of scientists from other disciplines were placing an unwarranted reliance on remote sensing to detect global change.

Prof. lees set up a research program to improve the reliability of change detection techniques. This led to work in adapting inductive and data driven modelling techniques to the predictive mapping of land cover and land degradation. Prof. lees and his students, have built up comprehensive GIS databases based on a range of field sites. These have been used to test, and refine, the use of inductive learning, and other artificial intelligence techniques such as neural networks and genetic algorithms, for environmental management. We have been very successful. Some of this work has been published, but some is currently in preparation, including new work on the impacts of DEM error, and on the rescaling of SRTM data.

Prof. lees set up a major database to test, refine, and develop these techniques at Kioloa field station (www.geography.anu.edu.au/associated/pathfinder/index.html). This was subsequently adopted as one of the 60 or so NASA lANDSAT PATHFINDER GlCTS PROJECT sites. This was NASA’s main high resolution, long-term, land cover change detection project. NASA was seeking very high quality, high-resolution, data-rich sites for this project and it was a triumph to be one of the final selections. There were only four of these sites identified in Australia and the Kioloa site is the only one to have been completed. Through NIES and NASDA Prof. lees has received a considerable amount of support, and Japanese and NASA data for this site. The research activity of Prof. lees continues to be the development of tools to carry out integrated analysis of these data.

The third phase of research has been recently developed through the active encouragement of Professors Barry Garner and Ron Horvath. They encouraged thinking about, and application of some of the analytical skills and techniques I had developed to social geographic problems. This has led to encouragement of several PhD candidates, a human geographer, an ecologist and a geomorphologist, to consider tackling such problems.

In concert with established social researchers, such as Chris Devery and Jerry Ratcliffe, and the NSW Police, we have started applying geographical analysis to crime and disorder. Several papers have been submitted on the topic. This integration of quite diverse strands of geographic thought is proving very productive and several more projects are under consideration.

Predicting truffle growing areas in Australia

Dr David PaullThe Australian Black Truffle industry is a young and burgeoning enterprise. First established in Tasmania in the 1990s, productive truffle orchards or truffières are currently found in WA, SA, vic and NSW, with immature plantings also in SA and Qld. In these truffières, the fungus Tuber melanosporum is inoculated onto the roots of host trees, including oaks and hazelnuts. Maturation of Australian truffles occurs in winter, which is the Northern Hemisphere off-season, thus creating an export niche to high demand markets in Europe and Asia. This study aims to map existing Australian truffières, characterise their physical geography and predict the distribution of land that may be suitable for future production. To date no rigorous attempt has been made to identify the places best suited for truffles and their host trees but it is generally recognised they grow well in free draining soils where summers are hot and winters are cold. Other factors that determine success of truffières include access to water for irrigation

Classifying urban green space distribution: Analyzing spatial relationship of human-natural process by integrating remote sensing and socioeconomic data

Jin Cui ([email protected]) MScField of Study: Geographic Information Science

Research over the past two decades has highlighted the many benefits of urban green space brought to human beings. The spatial

distribution of urban green space is influenced by human activities and social economic development through time. Cities can be seen as sustainable ecosystems, but the connection between urban green space, socioeconomic and biophysical factors in varying combinations, and quality of life is not comprehensively understood. The focus of the project is to use GIS and remote sensing to investigate how these factors interact in space and time.

Developing a spatial database and GIS application for natural resource assessment and management for sustainable development in coastal Orissa, India

Shibani Mishra ([email protected]) PhDField of Study: Geographic Information Systems

This research focuses on developing a public participation GIS for the sustainable management of fisheries resources in Orissa, India. Currently, the fisheries resources at Chilika lake are threatened by over-exploitation and environmental pollution. Barriers to the sustainable development of this area include a lack of updated environmental information and the lack of a method whereby residents of the region can participate in making decisions that affect the lake’s resource base. This research involves developing a public participation GIS that will both be a repository of current environmental information and provide a forum through which village members can cooperatively work to develop a management strategy that will satisfy the needs of village members without destroying the resource base.

Multi-agent spatial modeling of Equine Influenza

Bahaa Eldin Aly Abdel Alim Abdel Hamid ([email protected]) PhDField of Study: Geographic Information Science

This research aims at designing and developing an integrated modeling framework for studying the dynamics of spread of infectious diseases. The framework incorporates several modeling approaches ranging from the classical system of differential equations to the more sophisticated and spatially explicit Cellular Automata and Agent Based approaches. It should be able to handle different data availability situations as they arise in the different stages of a disease outbreak. It can be used to study the behavior of various hypothetical disease spread scenarios and test the outcomes of various prevention, containment and eradication strategies that can be directed to a potential outbreak before making any real investment in a certain strategy.

The central theme of Society and Space is that the physical and built environments interact with society in complex ways. Sometimes it is necessary to examine issues at various scales of analysis to understand this interaction. PEMS supports one of the few combined physical and human geography groups in the country. This places the School of PEMS in a unique position to continue a close dialogue between physical and human elements of the environment in order to address important social and environmental problems.

These problems include:

• Urban design and transport efficiency and sustainability

• Effective speeds of different transport modes

• The links between sport and health

• The links between transport and health

• The importance of ‘region’ to the wine industry

• Globalisation and its effects on local communities

• Strategies of resistance to globalization

• The geographies of children’s play in school grounds

• Urban and peri-urban agriculture for food security, job creation and post-conflict reconstruction (South Africa, Zambia, Sierra leone)

• The threat of squatter resettlement on informal sector livelihoods (Fiji)

• land tenure insecurity and community-based agriculture (South Africa)

• Economic openness, cultural obligations and the emerging landless (Samoa)

• ‘liveable’ cities and child-friendly environments

• Implications of peak oil for liveable cities and child-friendly environments

• Mapping and understanding the drivers of human health and disease

• The geography and cultures of institutions (including the military and the academy

Current ResearchDr Amy GriffinWhile the majority of Amy’s research interests fall under the purview of the Geographic Information Science research group, she also actively undertakes research related to sport and space, the health implications of humans’ interactions with the natural, built and social environments, and a spatiotemporal analysis of Australia’s involvement in the vietnam War.

Her current research projects include the following:

The muscle trade

Dr Amy Griffin (with Dr James Connor)This project is examining transfers of allegiance (i.e., nationality change) of international track and field athletes competing at IAAF-sanctioned events, such as the World Championships, the Olympics and World Cup events. While international athlete migration has been studied extensively for sports such as association football, relatively little is known about either migration patterns or the drivers of migration for other sports.

Time scarcity: Another health inequity?

Dr Amy Griffin (with Dr lyndall Strazdins, Professor Dorothy Broom, Dr Cathy Banwell, Dr Jane Dixon, Dr Rosemary Korda, Dr Francesco Paoloucci, Australian National University; Associate Professor John Glover, University of Adelaide; and Ms Megan Shipley, Ms Marian Esler, FAHCSIA)This project seeks to develop a measure of time scarcity that can be used along with other measures of disadvantage, such as income scarcity, to examine the potential effects of policy decisions and their impacts on human health. We seek to describe time (and space-time) as a health resource that can have substantial impacts on individuals’ and families’ abilities to undertake healthy behaviours (as well as avoid unhealthy behaviours).

Understanding low intensity conflict

Dr Amy Griffin (with Dr Bob Hall and Dr Andrew Ross)This project is undertaking a fine-grained spatial and temporal analysis of Australia’s involvement in the vietnam war. In it, we seek to provide a clear understanding of low-intensity conflict (e.g., guerilla wars), using the vietnam war as a model. We are trying to answer questions such as the extent to which interactions between Australian and vietnamese troops clustered along rivers, tracks, at certain times of the day, and the extent to which the war unfolded in a series of temporal phases that are commonly used to organize discussions of the war.

The geography of humour and the role of humour in social change

Dr Scott SharpeHumour can serve the function as a sort of breaching experiment, showing cultural and societal norms in the very act of transgressing them. This project explores the potential of humour for producing, maintaining and transgressing social norms. looking at humour from a spatial perspective offers insight into the way

humour functions from its challenge to reason and rationality to its use of displacement and incongruity. In conjunction with Dr Maria Hynes (ANU), this project re-theorizes humour to emphasize its affective and ethical dimensions, rather than its ideological and moral ones.

The relationship between space, thought, perception

Dr Scott SharpeThis project examines the relationship of space, thought and perception. Centering on presumptions concerning the academy’s relation to the ‘world’, this project theorises space as an enfolding of thought and matter. Such a theorization allows a rethinking of the relationship of micro- to macro-perceptions, the relationship of the unconscious to consciousness, and the relationship of surface to depth. The project examines issues such as the new possibilities for fieldwork in light of critiques of representation, and the relationship of thought to social action.

The geography of sport

Dr Scott SharpeThis project examines the role of economy, affect and sport and the extension of traditional landscapes of sport by multi-national sportswear corporations. Conducting a semiotic analysis of sportswear advertisements and examining brand positioning in major sporting tournaments and events, the project explores the role that affective drivers have on fans, sub-cultures and wider society.

Dr Paul TranterMany of Paul’s research interests have had an important element of social relevance. He has applied geographical concepts and methodologies to the study of such topics as: pathological events (e.g. accidents, depression); residential privacy; tenant participation in public housing; transport provision in disadvantaged areas; children’s road safety and independent mobility; local authority attitudes and policies towards sustainable transport; the health implications and messages associated with motorsport; possible links between motorsport and illegal street racing; and children’s use of school grounds for environmental learning.

Paul’s current research projects include the following:

Peak oil and children

Dr Paul Tranter (with Dr Scott Sharpe) This project investigates how the challenge of peak oil might provide opportunities for making cities more child friendly. Currently children’s access to many spaces in cities is premised upon and restricted by the availability of cheap oil. From being restricted to designated play spaces to being transported to activities in private motor vehicles, cheap oil features prominently in the lives and opportunities of children. However, what the likely changes to children’s lives and opportunities when the global production of oil reaches a peak, and then declines?

Popping the bubble-wrap: unleashing the power of play

Dr Paul Tranter (with Professor Anita Bundy, Dr Shirley Wyver and Assoc. Professor Geraldine Naughton).This project aims to promote active, social and creative play amongst children in a primary school, by introducing a range of

loose materials into the school ground. This research has important implications for childhood obesity, bullying and mental ill health, all of which are serious childhood problems that are notoriously difficult to treat. Our research is developing and testing the effectiveness of a pilot intervention to promote active outdoor play.

Slowing down in the community: Reducing the speeding behaviour of motorists through cultural change

Dr Paul Tranter (with Dr James Warn and Dr Murray May)This project, funded by an NRMA ACT Road Safety Trust grant, seeks to develop a holistic model in order to reframe the way in which the wider community and policymakers perceive road safety. Our research is developing holistic, social-ecological model of reconnecting road safety with communities that value quality of life and slower ways of being. For example, improving road safety through reduction in the volume and speed of motorized traffic is integrally related to enhancing health and fitness, reducing greenhouse gas emissions, and improving neighbourhood planning and community cohesion. In this regard, community-based travel behaviour change initiatives are reserving much greater attention in the road safety area. As well as these changes at the personal and community scale, there is a need for policy changes to urban and transport planning that address the broader issues of sustainability in an era of climate change and peak oil.

Institutional capacity building in Africa

Dr Alec ThorntonThis research intends to improve the capability of research institutes in Zambia and South Africa to inform public policy for poverty alleviation. The wide spread and informal practice of urban and peri-urban agriculture (UPA) among the urban poor will be explored through key informant interview and household questionnaire surveys in selected sites in South Africa and Zambia. Through collaboration with colleagues at the University of the Free State (SA) and the University of Zambia (UNZA), the main outcome of this research is:

• To develop the capacity of these research institutions to carry out base-line research at the community level and

• To specifically enable them to work in the area of UPA and advise local and national governments about the potential of UPA to address poverty, unemployment and food insecurity issues.

The role of the church in development in Samoa

Dr Alec ThorntonThis research seeks to explore relationships between social change and social patterns in Samoa. This research is premised on the idea that increasing economic hardships in Samoa are challenging traditional practices, such as financial and material reciprocity

amongst the aiga (extended family) and the Church. People are opting out of these customary practices and, as a result, find themselves alienated from the familial benefits of these practices, such as the distribution of land resources and remittance income. This research will conduct key informant interviews with spiritual leaders from various religious denominations and household questionnaire surveys in known low-income areas in and around Apia, the Samoan capital city. In doing so, this research seeks to reveal the extent of which relationships and attitudes in Samoan society are changing, with regards to the needs of the church and the needs of the people.

The impact of economic openness on small-scale industries in Samoa.

Dr Alec Thornton Increasing vulnerabilities due to natural disasters and reliance on remittance income in Samoa have inspired grassroots movements to form associations of food and cash crop producers, using locally-sourced raw materials and labour, as a means to offset environmental and economic uncertainty. In parallel, these uncertainties underpin the Samoan government’s plans to expand into global trade. However, the potential impact of economic openness on the sustainability of small-scale agricultural initiatives has not been investigated. This research will explore how systemic changes in the local economy affect the economic viability and sustainable management of the ‘commons’ by small-scale, community-based industries (CBIs) in Samoa. These issues will be pursued through a combination of theoretical exploration and data collection of the causal linkages between systematic macro-economic reform and micro-level responses and the effects of trade liberalization on strategic decision making of CBIs.

Urban and peri-urban agriculture (UPA) in Freetown, Sierra Leone.

Dr Alec Thornton

This research, in collaboration with Fourah Bay College (FBC, University of Sierra leone), explores the role of urban agriculture as a post-conflict reconstruction strategy among the urban poor in Freetown, Sierra leone’s capital city. During the decade-long civil war (1991-2001), rural inhabitants fled their burning villages for refuge in Freetown. For many rural-urban migrants, food production in the city was a necessary survival strategy. However, the role of urban food production also provided a vital lifeline for city dwellers, in terms of food supply, particularly during the rebel embargo. This research collaboration seeks to build the capacity of the Geography Department at FBC to carry out baseline research in the area of UPA. Through a combination of UA-producer questionnaires and key informant interviews, this research seeks to facilitate the establishment of a formal UPA policy for post-conflict reconstruction and ensure the availability of a fresh and affordable local food supply.

Student ResearchA dynamic electorate? Analysing the geography of minor parties at Australian state and federal elections, 1997-2006

Stephen Smith ([email protected]) PhDField of Study: Electoral Geography

My doctoral research aims to investigate and explain the electoral geography of minor parties through assessing their changing electoral performances, presence and participation in Australian electoral settings at state and federal elections held between 1997 and 2006. To achieve this aim, six minor parties have been investigated: Australians Against Further Immigration, Australian Democrats, Family First, the Greens, One Nation and Unity. Exploring spatial and temporal variations in minor party electoral performances and their implications for the continued participation and presence of minor parties have also been of interest for this research. This has been exemplified through candidate standings, constituency formation and political engagements undertaken by these parties across electoral settings. This thesis is intended on highlighting challenges that are faced by minor parties as political participants in regards to their respective electoral prospects in a contemporary electoral setting.

Bushfire risk assessment at the urban-bush interface in metropolitan Australia: An integrated modelling approach

Daminda Solangaarachchi ([email protected]) PhDField of Study: Geography

In many parts of Australia there has been growth in the population at the urban-rural interface. This population growth is a result of people choosing an idyllic lifestyle to live at the rural-urban interface, or un-affordability of housing within urban areas for those who earn a low income. The environment which draws people to these locations is fire prone and there is a potential threat to lives and property. Although there have been many unforgettable bushfire events with significant impacts, the lack of a risk assessment framework has been the primary limitation to quantitative risk assessment. It is clear that a systematic approach to assess bushfire risk while combining hazard occurrence, social/physical vulnerability and community resilience is required to determine activities of the disaster managers at all phases of the disaster management cycle i.e. pre-event, during the event, post-event. This will help to determine how scarce resources should be utilized in a more effective manner to minimize the impact of the event. Furthermore, it will help to identify the locations of the communities which need assistance in advance. This will also help to make a proper evacuation plan by prioritizing areas when a mass evacuation is required. This research will develop a

conceptual model of risk that provides a holistic perspective on natural hazards risk assessment with reference to bushfires. It will incorporate hazard, social vulnerability, physical vulnerability, and the resilience of the urban bush interface.

Cyberspaces: A cultural geography of online communication

Annabel Beckenham ([email protected]) PhDField of Study: Cyberspace Research Topic: Cultural geography of cyberspace

Cyberspace is a field which belies traditional notions of space bound communities, but which enables the development of social groupings which have, among other things, distinctive territories and citizenries, recognisable pasts, variegated futures and complex interrelationships with space bound groups. The thesis examines the development of social navigation points in three major social network sites; Facebook, Second Life and Myspace.

Peak oil and temporary migration

Hao Duan ([email protected]) PhDField of Study: Human Geography

This project explores the relationship between travel costs and lives of temporary migrant workers, in light of higher travel cost associated with peak oil. Peak oil describes the possible future of oil scarcity, where demand for oil outstrips our capacity to produce it. Peak oil may have a significant influence on fuel prices and directly affects the migrant workers’ travelling costs. Temporary migrants are likely to change their behaviours in the context of peak oil. long-distance commuters, who are regarded as an important group of temporary migrants, are studied on their adaptive behaviours, their relationships with family members, communities, businesses, and governments. The study expects to help authorities cope with likely impacts of peak oil on long-distance commuters.

The AIM Research Group focuses on using Applied Mathematics and Statistics to investigate a diverse range of real world problems. The emphasis is on actual real-life situations and an interaction with industry with the aim of producing real solutions.

The key steps to our research endeavours are the analysis of real world problems; the formulation of the problem in mathematical terms; the use of that formulation to provide an understanding of the nature of the problems and how they may be solved; and the communication of the outcomes to both the originators of the problems and the wider applied mathematics research community.

Group members call on the vast range of mathematical and statistical techniques supplemented with the application of extensive modern computing methods. The range of techniques and the mathematical thinking skills that experience develops results in an extraordinarily flexible and powerful approach that can be adapted to a huge set of different practical problems as illustrated by the list of projects.

The interdisciplinary nature of the work and the constraints imposed by dealing with genuine practical problems make this a challenging and rewarding area for research. The importance and value of the work is recognised by the success of the group members in obtaining grants and willingness of industry to offer financial support.

Defence applications

Geoff Mercer, Harvi Sidhu, Steve Barry• Minimising detection by enemy radar

• Safest routes through minefields

• Dynamic route changes in real time to minimise risk

• Optimal route for aerial surveillance of ships

• Effects of classification range and turning radius on optimal routes

• Travelling salesman problem applied to aerial surveillance

Different aspect of travel through a risk environment are studied. Determining the minimal detection route through an area under radar surveillance using differential equation based models. This has application to Unmanned Air vehicle (UAv) deployment and design issues. Calculation of the safest route through a minefield when information on the location of the mines is only discovered once travel is underway. Solutions must be able to be calculated in real time. Many aspects of the aerial surveillance of maritime regions including use of a modified dynamic travelling salesman problem to determine the visiting order of detected but as yet unclassified ships and aspects of the airplanes capabilities such as turning radius. This is joint work with DSTO Air Operations Division.

Design of large area mode fibres

Isaac Towers & Zlatko JovanoskiSingle-moded optical fibres are preferred for optical communication and for high power applications. The small core of a conventional single-mode fibre leads to high power densities and gives rise to significant unwanted nonlinear optical effects. Nonlinear effects in a fibre can distort the pulses at high bit rate and can produce crosstalk among the closely spaced wavelengths. However, the use of large-core conventional fibres to overcome nonlinear effects is not advisable as the large number of modes in such a fibre reduces the data transfer rate in an optical communication system and affects the beam quality in fibre lasers. It is therefore preferred to use a fibre with a large core yet supporting a single guided mode. The goal of this project is to investigate designs for optical fibres which maximise mode area but allow only a single mode to propagate a meaningful distance.

Dynamical systems

Harvi Sidhu, Geoff Mercer, Richard Pennifold, Zlatko Jovanoski

• Analysing chaotic behaviour

• Dynamics in ecology

• Spread of diseases

• Estuary behaviour

• Forced systems

We utilize methods and techniques from nonlinear dynamics theory such as bifurcation and singularity theories to investigate complex real-world phenomena such as population interactions in ecology, spread of diseases, dynamics of shallow estuaries under drought conditions and forced systems. We also investigate new methods to quantify chaotic behaviour in dynamical systems.

Frailty modelling

Joanne Chapman with Prof. Robin HendersonRandom errors and unmeasurable association within clusters cannot be assumed Normally distributed and ignored in survival analysis as in other areas. The frailty term is introduced to represent these unknowns. A typical assumption is that the frailty variable follows a gamma distribution. Models which extend existing models and allow for the possibility of negative correlation within clusters (as often seen in animal litters) are being developed.

Industrial process modelling

Geoff Mercer, Harvi Sidhu, Steve Barry• Wool scouring

• Porous filtering

• Wastewater treatment

• Compost

• Bioreactors

• Bloom in chocolate

• Submarine battery charging

• Wine fermentation

Many different industrial processes are studied with in the research group. These research areas have often been initiated by members attendance at the annual Mathematics in Industry Study Group.

Mathematics in Industry Study Group

Geoff Mercer, Harvi Sidhu, Steve Barry, Rod Weber, Roslyn Hickson, Richard PennifoldMembers of the AIMRG are actively involved in the annual Mathematics in Industry Study Group (MISG). They have, and continue to, moderate many problems at the MISG. This provides a rich source of new and exciting research areas of direct relevance to industry.

Modelling extreme temperature effects on living tissue

Geoff Mercer, Harvi Sidhu, Steve Barry• Skin burns

• Models of skin burns subject to fire exposure

• Automotive airbags

• Design of firefighter clothing to minimise skin burn

• The effect of cold water on a swimmers core temperature

• Modelling hypothermia

• Wart freezing

Human skin and subcutaneous tissue is a complex organ designed to efficiently cope with a wide range of temperatures and conditions. However, at extremely high temperatures, such as exposures during fires or explosions, the skin is unable to transport the heat away fast enough and burns occur. Similarly, at cold temperatures, the skin is unable to insulate properly causing long term heat loss and hypothermia. We look at various models of heat transfer through the skin and subcutanious tissue to better understand this behaviour.

Numerical schemes for parabolic partial differential equations

Isaac Towers

This research project is to develop and implement numerical schemes which solve multi-dimensional partial differential equations (PDE). By using an appropriate set of orthogonal basis functions the goal is to create a spectral method which allows for boundary conditions at infinity while maintaining the speed of an explicit time-marching approach. Operator splitting, integrating factors and the so-called explicit exponential methods are being investigated.

Numerical schemes for simulating optical beam propagation

Isaac TowersTo compliment theoretical investigations of nonlinear optical beams we develop numerical schemes to efficiently study beam propagation. A variety of techniques are being investigated to provide fast and accurate simulations.

Plant and disease spread

Steve Barry, Geoff Mercer, Harvi Sidhu, Roslyn Hickson• Models of weed spread

• Intervention strategies

• Seed banks

• Flood events

There are several current models to simulate the spreading of weeds (or any population) in the environment, involving reaction-diffusion equations, integro-difference equations, cellular automata systems, SIR ordinary differential equation, stochastic differential equations, among others. We are currently developing PlANTSIM, a Matlab based package, which allows users to simulate and compare numerous population spread simulation models in either real or artificial situations. A key feature is the Graphical User Interface which allows users to manipulate the complex parameter data sets involved in real simulations. PlANTSIM allows the user to overlay, visualise and manipulate parameter data on satellite imagery, and then run a collection of different simulation routines, with output automatically visualised in a variety of formats with key results summarised and graphed in generated laTeX and pdf files.

Additional work is being done on formulating new models for weed spread, particularly along river systems. This is being applied to the spread of lippia in the Murray-Darling system.

Statistical Ecology

In order to ensure the survival of animal populations it is essential to be able to estimate mortality rates in the wild. Two ways of doing this are from the recovery of bands from animals found dead, and from mark-recapture experiments. Models involving survival, recapture and recovery probabilities as unknown parameters, are developed and fitted.

The following projects are currently being undertaken in this area:

Effect of banding on juvenile Little Penguins Eudyptula minor

Leesa Sidhu and Ted CatchpoleThis work is being conducted in collaboration with researchers from the Phillip Island Nature Park. For more than 50 years, researchers have been marking penguins with flipper bands. Studies of Adélie Penguins and King Penguins have shown that banded penguins have lower survival rates than unbanded birds, and that they use more energy than unbanded birds when swimming. Our earlier work in this area was the first to study the effect of banding on little Penguins. We showed that banding had a detrimental effect on the survival of adult penguins, with banded birds having an annual survival probability 6% lower than unbanded birds. While the effect of banding on juvenile little Penguins is currently unknown, it is likely that banding significantly reduces the survival of young birds, particularly in their first year of life, and that our existing estimates of first-year survival underestimate the true survival probability for unbanded birds. A study examining the effects of banding on juvenile little Penguins is currently underway on Phillip Island. The main aim of this project is to analyse the data from the Phillip Island study, in order to obtain estimates for survival for banded and unbanded juvenile little Penguins, and for band loss in penguin chicks. The Department of the Environment and Heritage will use the results of this project, together with those from our earlier work, to determine whether banding of little Penguins will be allowed to continue in Australia.

Analysis of recovery/recapture data for Pacific Gulls Larus pacificus

Leesa Sidhu and Ted CatchpoleThis work is being conducted in collaboration with researchers from la Trobe University. The Pacific Gull is the only large gull occurring naturally in Australia. There is evidence that its population size is falling, its range contracting, and that it could become extinct. While earlier studies of Pacific Gulls have focused on their biology, there are no existing survival estimates for these birds. This study will be the first to produce age- and time-varying survival estimates for these birds, by analysing a long-term mark-recapture-recovery dataset. Such a study is crucial to improve our understanding of these birds, and to ensure the survival of this species.

Analysis of recovery/recapture data for Short-tailed Shearwaters Puffinus tenuirostris

Leesa Sidhu and Ted CatchpoleThis work is being conducted in collaboration with researchers from la Trobe University. Short-tailed Shearwaters have been studied continuously on Fisher Island, Tasmania since 1946, making it one of the longest continuous studies of any wildlife population in the world. Although life-history data have been collected sporadically over this time period, a detailed mark-recapture-recovery analysis has not yet been conducted. This study will produce age- and time-varying survival estimates for Short-tailed Shearwaters, and examine the effect of individual covariates such as egg size on first year survival.

Comparing first year survival for Little Penguins Eudyptula minor in Phillip Island, Australia and Oamaru, New Zealand

Leesa Sidhu and Ted CatchpoleThis work is being conducted in collaboration with researchers from the Phillip Island Nature Park , the Department of Conservation, New Zealand and the Institute of Marine Research, Norway. While the Phillip Island study has been underway for almost 40 years, the New Zealand study consists of six years of data. Here we estimate and compare the survival of penguins in these two locations and determine to what extent the conclusions of covariate dependence of survival can be extended from Phillip Island to another penguin colony.

Stefan problems with two moving boundaries - modelling swelling processes

Steve Barry, Geoff Mercer, Harvi Sidhu• Cooking of whole grains

• Swelling of polymer implants in drug delivery

• Exact and asymptotic solutions of Stefan problems

• Swelling of grease layers on wool fibres

During the cooking of whole grains, or the swelling of grease, water diffuses into the outside of the grain causing the outer boundary to swell. This creates a partially swollen region which expands inwards and outwards over time. This then leads to a diffusion problem where the two boundaries defining the diffusive region move (a Stefan problem). We consider modelling this process and finding exact, numerical and asymptotic solutions to the system.

Student ResearchCritical times of multilayer diffusion

Roslyn Hickson ([email protected]) PhDField of Study: Applied Mathematics

Diffusion through multiple layers has applications to a wide range of areas in heat and mass transport. An important aspect of multilayer diffusion is the `critical time’, which is a measure of how long the diffusive process takes.

This project involves using an exact solution for multilayer diffusion to demonstrate the limitations of traditional averaging methods, which only work for a large number of layers or in the steady state. This solution is used to find a better approximation for a particular definition of critical time. The work is then extended to reaction diffusion models, with application to invasive plant spread.

Coarse woody fuel availability and consumption in Australian forest fires

Jennifer Hollis ([email protected]) PhDField of Study: Statistics

After the passage of a fire front it is the larger, coarse woody fuels (>6mm diameter) that once ignited by fire, that will greatly influence: total energy output; convection column development; fire behaviour; greenhouse gas emissions; air quality; damage to biotic elements; soil heating; habitat quality; suppression/mop-up difficulty; and potential for re-ignition.

The focus of this research is the determination of proportion of woody fuel consumed and rate of consumption as functions of fire intensity; season; fuel type; and fuel condition in Australian forests. The research also includes testing current empirical and physics-based models of woody fuel consumption and the development of a fuel consumption model suitable for Australian eucalypt forests.

The outcomes of this research will assist the better management woody fuels. The Australian Woody Fuel Consumption Model developed can be incorporated into fire management decision support systems assisting fire and land management agencies to better predict the total fuel consumed in prescribed fires and wildfires and enhance planning for expected fire behaviour, smoke and greenhouse gas emissions and associated fire impact.

Dynamical systems behaviour of the Forced Bonhoeffer Van der pol equations

Richard Pennifold ([email protected]) PhDField of Study: Applied Mathematics

The forced Bonhoffer van der Pol equations provide a description of how nerve impulses travel down the axon of a squid nerve cell under external stimuli. Previous work used bifurcation diagrams and lyapunov exponents to explore the dynamics of this system. In our study we use continuation methods to clarify the bifurcations of the periodic orbits which had previously been ambiguous. We have developed numerical tools, such as the shooting and Galerkin

methods. We also use the recent 0-1 test for chaos and conclude that this test offers a number of advantages over the lyapunov exponent test. We have also used analytical and semi-analytical methods to determine approximate solutions to the system. We will also analyse the coupled Bonhoffer van der Pol system. The key point of our study is to develop an array of methods (both numerical and analytical) to enable accurate investigations into forced systems.

Forest flammability - modeling and managing a complex system

Philip Zylstra ([email protected]) PhDField of Study: Forest fire behaviour

The intent of the project is to develop a complex systems model of fire behaviour which can demonstrate quantitatively the role of different fuel strata, species, dimensions and individual weather parameters in fire behaviour, allowing for more effective management of forest flammability.

Mathematics modeling of self-heating in compost piles

Thiansiri Luangwilai ([email protected]) PhDField of Study: Applied Mathematics

The phenomenon of spontaneous ignition due to internal heating in bulk solids such as coal, grain, hay, wool wastes, etc., can be described by thermal explosion theory. In such models heat release is usually represented by a single Arrhenius reaction and combustion is initiated when heat-loss is unable to balance the heat generated by the internal heating of the bulk material. However in industrial processes involving large volumes of bulk organic materials there are in fact two sources of heat-generation: a low-temperature process involving the growth and respiration of micro-organisms, such as aerobic mould-fungi and bacteria, and a high-temperature process due to oxidation of cellulosic materials. Examples of processes where biological heating is important include large-scale composting operations, the storage of industrial waste fuel, such as municipal solid waste, and landfills. In these examples, self-heating due to biological activity is considered desirable, for example in composting. Elevated temperatures of the order 70-90 degree Celsius may be found within a few months or even a few days. Although it has been recognised for over twenty years that biological heating may be an indispensable prelude to self-ignition, very little information is available regarding the mechanism of fires when biological self-heating is involved, despite fires occurring at landfills worldwide. In my PhD program I intend to extend the basic models to include more realistic features such as oxygen consumption, advection through the compost pile, as well as the inclusion of moisture. I will analyse these in both one- and two-dimensional geometries. We believe that the results of my PhD will be one of the first, comprehensive mathematical studies to explain the self-heating process in industrial size compost piles

Conference ParticipationFrom 28 January-1 February 4 2008 Geoff Mercer, Steve Barry, Zlatko Jovanoski and Roslyn Hickson attended the annual Mathematics in Industry Study Group (MISG).

Geoff Mercer, Harvi Sidhu, Steve Barry, Rod Weber and Roslyn Hickson attended the annual Australian and New Zealand Industrial and Applied Mathematics (ANZIAM) Conference in Katoomba from 4-7 February 2008.

PhD student Roslyn Hickson was awarded funding to attend both the Graduate Industrial Mathematics Modelling Camp and the Industrial Problem-Solving Workshop (IPSW) at University of Regina, Canada from 9-20 June 2008. For the IPSW she worked with a small group on a local area positioning problem from Accutrak. Accutrak research, design and develop accurate steering systems for agriculture. This particular problem involves determining the location of a tractor relative to beacons which have been placed around a field. The beacons communicate with the tractor receiver via a particular frequency with a known wavelength. Accutrak’s system cannot determine the integer number of wavelengths from the beacons to the receiver, however it can detect the fractional component of the wavelength. To find the position of the tractor the fractional components from at least 3 beacons are used to set up a system of nonlinear equations. This system is not trivial to solve, but the real complexity comes from the variety of sources of errors within the system. GPS is not sufficiently accurate for this task, as its reliable accuracy is only ±10 metres for moving objects.

At the Australian Statistical Conference in Melbourne in 30 June-3 July 2008, 41 early career statisticians contested the EJG Pitman Prize for the most outstanding talk by a student or recent statistics

graduate. Leesa Sidhu, with her talk entitled “little Penguins: to band or not to band?”, was one of four early career statisticians who received an honourable mention for presentations that achieved a very high standard.

At the 14th Biennial Computational Techniques and Applications Conference held at ANU (13-16 July 2008), 5 academic staff members from PEMS (Zlatko Jovanoski, Isaac Towers, Steve Barry, Geoff Mercer and Harvi Sidhu), 2 PhD students (Roslyn Hickson and Richard Pennifold) and a CDF student (Martin Rowe) presented a total of 10 talks. Geoff and Harvi were also on the organizing committee of this important national conference.

The 2008 joint NSW/ACT Australian and New Zealand Applied and Industrial Mathematics branch mini-meeting was held at Batemans Bay 21-22 November 2008. The organising committee for the minimeeting comprised Dr M.I. Nelson (Uni Wollongong) and Harvi Sidhu (UNSW@ADFA, PEMS). The meeting had a strong PEMS delegation giving a wide variety of talks from ethanol production, compost modelling, bush fire modelling, analysing the effects of diffusion in multilayer media and wastewater modelling. Everyone agreed that our students Thiansiri and Roslyn gave excellent talks. Roslyn was specially singled out with a highly commended award.

Geoff Mercer and Harvi Sidhu attended the 7th Australia and New Zealand Mathematics Convention at University of Canterbury, Christchurch from 8-12 December 2008. Harvi was the invited speaker for the “Applied dynamical systems in engineering and the physical sciences” session. His talk was titled “Classical and pulsating combustion waves in a chain-branching reaction model”. Geoff, gave a talk titled “Determining a safe path through a dynamic threat environment in real time”. Part of this work was undertaken

Roslyn Hickson attended the Maths in Industry Study Group (MISG) in Wollongong, held from 27-31 January 2009. She was the student moderator for the ‘Coil Slumping Problem’ sponsored by Bluescope Steel. Bluescope Steel manufactures, stores and transports steel strip coils. The current limiting step of this production, from an economic perspective, is the unpredictable ‘coil slumping’ which occurs when the coil cannot hold up its own mass and maintain the integrity of its cylindrical shape. Even minor slumping is an issue, and the cost of an individual coil is such that even the loss of one coil in a thousand is unacceptable. There was much lively debate over an appropriate approach to the problem, making for an exciting and interesting week.

Roslyn Hickson gave a presentation at the ANZIAM Applied Mathematics Conference held in Caloundra from 1-5 February 2009. From a field of 41 talks competing for the highly sought after T.M. Cherry student prize, Roslyn was awarded an honourable mention. At the conference Roslyn was also elected as a representative on the ANZIAM Executive Committee.

Roslyn Hickson attended the European Study Group with Industry on 30 March-3 April 2009 in Southampton, England. She mostly worked on a decontamination problem, with applications such as cleaning railway rolling stock, removal of traffic film from road vehicles, and graffiti removal. She also worked on an electric arc problem, with application to circuit breakers. There were approximately 80 delegates at the conference.

The following week she attended the British Applied Mathematics Colloquium on 6-9 April 2009 in Nottingham, where she presented her work titled “Critical times of multilayer diffusion”.

Jennifer Hollis spent the month of July 2009 with the Fire and Environmental Research Applications (FERA) team based in Seattle, Washington at the Pacific Wildland Fire Sciences laboratory (PWFSl). She met with Dr Roger Ottmar, a research forester with FERA and spent time in the office and field discussing woody fuel consumption equations from Consume 3.0, collaborating on a manuscript and discussing how the Fuel Characteristic Classification System could be adapted for Australia. On July 10th 2009 she presented a seminar at the Pacific Wildland Fire Sciences laboratory on woody fuel consumption in Australian forest fires, and on July 31st 2009 met with Dr Mark Finney at the Missoula Fire lab in Montana to discuss potential application of the Burnup model for predicting woody fuel consumption. From 6-10 September 2009 she attended the Institute of Foresters Australia Conference in Caloundra, Queensland and presented a conference paper and poster on “Woody fuel consumption and carbon in the changing climate of Australia”.

VisitorsMark Nelson, an applied mathematician from the University of Wollongong, spent a significant part of his SSP in PEMS (2008) with Harvi Sidhu, and other members of the Applied and Industrial Mathematics group working on various chemical/biochemical engineering problems, including optimising ethanol production through continuous fermentation, modelling of heat generation from composting, ignition of coal piles and modelling the passage of food down the human/animal gut.

In early 2008, Leesa Sidhu and Ted Catchpole were visited by Mr Bruce Robertson, a biologist studying Pacific Gulls. The aim of the visit was to discuss the details of the data collection and the biology of these birds, to enable leesa and Ted to analyse the mark-recapture-recovery data.

Leesa Sidhu and Ted Catchpole hosted a visitor, Dr Peter Dann, from 2-4 February 2009. Peter (also known as the “Penguin Man”) is the Research Manager of the Phillip Island Nature Park. The purpose of the visit was to continue their study of the effect of banding on the survival of adult and juvenile little Penguins. The results of these analyses will be used by the Department of Environment and Heritage to determine whether banding of little Penguins will be allowed to continue in Australia

Dr Vladimir Gubernov visited PEMS from 3 March-1 April 2009. vladimir is from the P.N. lebedev Physical Institute of the Russian Academy of Sciences and his visit was funded by the Rector’s visiting Fellowship scheme. During his visit, he worked closely with Harvi Sidhu and Jason Sharples to investigate instabilities in multi-step combustions models. vladimir is well known in the mathematical combustion modelling community for his expertise in using intricate mathematical methods to illuminate complex behaviour. later this year, Jason will visit vladimir at his institution in Moscow.

Prof. Swapan Konar from the Birla Institute of Technology, Mesra, Ranchi, India was funded as a visiting Fellow to PEMS. He visited PEMS during 15 May-15 July 2009 and worked with Isaac Towers and Zlatko Jovanoski in the area of optical solitons.

Current ResearchDr Andrew Kiss

Nonlinear dynamics of ocean currents

Dr Andrew KissComputer models of ocean circulation typically feature western boundary currents (WBCs, such as the Gulf Stream and East Australian Current) which separate much further downstream than in reality, producing large errors in ocean/atmosphere heat fluxes and therefore in water properties. Attempts to rectify this problem have been hampered by a lack of theoretical understanding of the dynamics responsible for separation. I am using high-resolution ocean models to investigate whether the separation mechanism I discovered in idealised models (Kiss, 2002) also applies in a more realistic setting. A related aspect of this work also involves collaboration with Dr M. Roughan and H. McDonald (UNSW). The insights gained from this research may lead to improved accuracy in ocean and climate models.

I am also studying the extent to which variability in realistic WBCs is determined by wind forcing, internal instabilities, or nonlinear interactions between the two, following on from previous work with idealised models (Kiss, 2007). This may provide insights into the origins of the pronounced variability seen in the East Australian Current.

Ensemble methods in ocean modeling

Dr Andrew Kiss collaborative project with PhD student Robert Woodham, Dr Gary Brassington and Dr Oscar AlvesThe Bluelink ocean forecasting system has recently become operational, providing three-dimensional forecasts of ocean currents and temperature analogous to those produced by numerical weather forecasting. Robert’s PhD project is an investigation of the growth of forecast errors in the SHOC and OFAM components of the Bluelink system. Model sensitivity is being characterized by constructing ensembles of runs whose initial conditions are perturbed by simulated errors consistent with observational uncertainties, and using the divergent evolution of these runs to better understand the processes that limit the accuracy of long-term ocean forecasts. Error growth in OFAM has also been investigated and compared with persistence forecasts and climatology.

Dr Robin Robertson standing on sea ice near the Thwaites Ice Tongue with RvIB Nathanial B. Palmer in the background.

Dr Robin RobertsonIn general, Dr Robin Robertson investigates tides and their effects on circulation and mixing. She is particularly interested in internal tides and waves, which are tides or waves occurring below the surface of the ocean at density layers within the ocean. Most of her research involves numerical modeling using the Regional Ocean Model System (ROMS). However, she tries to participate in at least one research cruise every other year in order to stay in touch with the real world and to gain access to observational data for realistic simulations and model performance evaluation.

Internal Tides and Mixing in the Antarctic Seas

Dr Robin RobertsonInternal tides and the mixing they generate play a major role in climate in the Antarctic Seas, influencing sea ice, melting of the ice shelves, the heat flux from the ocean to the atmosphere, bottom water formation, etc. These factors affect the global thermohaline circulation and global climate. Dr Robin Robertson has been investigating tides, tidal currents, and tidal impacts for several Antarctic Seas: the Weddell, Ross, and Amundsen Seas. She is collaborating with Drs Craig Stevens and Mike Williams of National Institute for Water and Atmospheric Research in New Zealand for the Ross Sea and McMurdo Sound and they have recently received a Marsden Grant for this work. She went to the Pine Island Glacier, Amundsen Sea in Antarctica in 2009 with Stan Jacobs of lamont-

Doherty Earth Observatory of Columbia University to observe the changes in the Amundsen Sea associated with the rapid melting of the Pine Island Glacier. She is modeling the tidal circulation under the Pine Island Glacier and in the Amundsen Sea with honours student Scott Baxter and this work is being continued by PhD student Darrell Terry. The effects of tides on sea ice are being investigated with Dr Petra Heil of the Australian Antarctic Division.

Internal Tides and Mixing in the Indonesian Seas

Dr Robin RobertsonThe Indonesian Seas are the only low-latitude connection between the Pacific and Indian Oceans and the surface return flow of the global thermohaline circulation. As Pacific waters pass through the Indonesian Seas, they are mixed by the “Indonesian Mixmaster”. Tides have been observed to be one of the primary mixing mechanisms. Dr Robin Robertson has simulated the internal tides for the Indonesian Seas. The model results replicated the sparse observations in the region and filled in the picture of tidal fields between the observations. This work is continuing in collaboration with Drs Susan Wijffels and Andreas Schiller of CSIRO and Dr Janet Sprintall of Scripps Institute of Oceanography with the goal of including the mean currents in the simulations with the tides and determining an algorithm to include tidal mixing into larger scale models such as Bluelink or the global climate models.

Internal Tides and Mixing off Eastern Australia

Dr Robin RobertsonThe Eastern Australian Current (EAC) interacts with the chain of seamounts, including Taupo, causing upwelling and mixing. Prof. Jason Middleton and Dr Moniya Roughan of UNSW and Dr John Wilkins of Rutgers are investigating the interactions of the EAC with the seamounts. Dr Robin Robertson is simulating the interactions of the internal tides with the seamounts, focusing on tidal effects. She is also participating in research cruise with Drs Middleton and Roughan to investigate mixing around the seamounts on lord Howe Rise off Eastern Australia.

Vertical Mixing in Ocean Models

Dr Robin RobertsonBefore accepting the model results for mixing, Dr Robin Robertson has investigated the performance of nine different vertical mixing parameterizations in the Regional Ocean Model System (ROMS). The goal was to identify differences in performance and select the best performer for subsequent model simulations. As part of his PhD work, Darrell Terry expanded this work as his introduction to modelling with ROMS.

Dr Hua Wang

Oceanic nepheloid layers and their role in coastal oceanography

Dr Hua WangNepheloid layers in the oceans, formed through sediment resuspension events by waves and currents on the continental shelf, ‘shut down’ the bottom boundary layer processes and reduce mixing and hence transport of sediments and other materials. This project will develop and implement new numerical models to investigate the dynamic features of such layers including their highly nonlinear behaviours of resuspension hysteresis. The impact of such layers in determining coastal ocean and ecosystem dynamics and in transporting sediments from the rivers into the outer shelves of the marginal seas will be investigated. This project covers the coastal oceans such as Jervis Bay, NSW, the Adriatic Sea, Italy, the southwestern coast of Korea and East China and yellow Seas. The outcome of the project will result in new knowledge on the roles that resuspended sediments played in flow dynamics and the primary biomass production in the turbid coastal ecosystem environments.

IMOS (Integrated Marine Observing System) NSW node – Jervis Bay mooring

Dr Hua WangUNSW@ADFA researchers have investigated the oceanography of Jervis Bay and its adjacent shelf since 1988 spurred by the interest of Defence. In this proposal, we aim to construct and deploy a pair of moorings at a site off Jervis Bay to extend this data set. The primary purposes of the moorings are to provide real-time observational capability and obtain longer records to be used for on-going oceanographic and climate studies at UNSW@ADFA. All observations will be incorporated into IMOS (Integrated Marine Observing System) and BlueNet. Our mooring complements NSW-IMOS’ planned observational infrastructure.

Coastal environment management - Comparative study of marine protected areas in Australian and China

Dr Hua WangThe project aims to compare the legislative frameworks, management characteristics and impact of the ecosystems of the marine protected areas in Australia and in China. It is widely known that China has a growing interest in developing marine protected areas and management plans in its coastal zones whilst Australia has a well developed integrated coastal management system. This study will be a comparative analysis of the advantages and disadvantages of coastal environmental management systems in two countries. It is hoped that the present work can assist and enhance management of the marine protected areas both in Australia and in China.

Managing Australian Defence Force activities in marine protected areas - The environmental management of Jervis Bay and Shoalwater Bay Training Areas

Dr Hua WangThis project aims to study coastal management issues of Australia Defence Force (ADF) activities in Australian Marine Protected Areas, by analysing the Environmental Management Systems of Jervis Bay and Shoalwater Bay training areas. The research has important significance to the sustainable development of ADF training activities, ecology, environment, economy and society. At the completion of this project, we hope to provide experiences and lessons learnt from managing these two training areas in an environmentally sustainable manner; and to assist management of ADF training activities in other regions.

Student ResearchAn operational circulation and ecology forecast system for Jervis Bay, NSW

Donghui Jiang ([email protected]) PhDField of Study: Oceanography

In recent years, Jervis Bay, NSW, has increasingly been used by the RAN and DSTO as a trials area for equipment testing (e.g. Unmanned Autonomous Underwater vehicles with US Navy). In evaluation of the results of these trials, it became apparent that supporting environmental data for the bay was not available, or was insufficient for the trials. Furthermore, there exists very few 3-dimensional circulation modelling studies for the region. An exception is the study by Wang and Symonds (1999) that has a specific research interest of winter surface cooling.

This project aims:• To develop a Jervis Bay ecosystem database of relevant

environmental parameters encompassing the planned measurements and historical data.

• To develop a high resolution 3-dimensional hydrodynamic Jervis Bay circulation model coupled with a sediment and an ecosystem model.

• To calibrate/validate Jervis Bay circulation and ecosystem model with in-situ measurements.

Development of an environmental database together with operational circulation and ecology forecast models for Jervis Bay will enable more robust estimations of performance of technically complex developmental and Commercial Off The Shelf (COTS) systems.

From 27-29 July 2009, Donghui Jiang and Colin Symons conducted a field trip to Jervis Bay for deploying the PEMS new ADCP (Acoustic Doppler Current Profiler) and SBE 39 (Sea-Bird Electronics) Temperature Recorder at the site (S 35 04.600’  E 150 50.868’) in 70 m water depth off Jervis Bay. This is the UNSW@ADFA Ocean Reference Station in Jervis Bay and IMOS (Integrated Marine Observing System) NSW node-Jervis Bay mooring which has been maintained by Hua Wang (UNSW@ADFA).

Application of the ISO 14031 Environmental Performance Evaluation to the Australian Defence Force Environmental Management System

Wen Wu ([email protected]) PhDField of Study: Oceanography

Environmental management of military activities is of growing global concern by defence forces. As one of the largest landholders in Australia, the Australian Defence Force (ADF) is increasingly concerned with sustainable environmental management. Environmental management tools are employed to manage environmental performance, and the Environmental Management System (EMS) is used widely by the ADF. This project focuses on the Shoalwater Bay Training Area (SWBTA) as a research example to examine environmental management activities by the ADF. SWBTA is one of the most significant military training areas in Australia. With its maritime part within the Great Barrier Reef Marine Park (GBRMP) and the Great Barrier Reef World Heritage Area (GBRWHA), and abutting Queensland’s State Marine Parks, it is an important region with high environmental, ecological and heritage values. Therefore, it is difficult and complex to manage Defence activities in such an environmentally sensitive Marine Protected Area.

On the basis of reviewing the Environmental Management System (EMS), this project will focus on how the ADF EMS operates during military training, and how effective the Defence EMS is in minimizing environmental impacts and improving environmental performance in SWBTA. To sufficiently measure the Defence EMS effectiveness, the study will use the ISO 14031 Environmental Performance Evaluation (EPE) to develop a systematic environmental performance indicator framework by selecting a suite of environmental performance indicators (EPIs) specific to SWBTA. This framework will combine the EMS and the EPE through the EPIs. It can be used for identifying gaps between the ISO 14001 requirements and the Defence EMS steps, evaluating the ADF environmental performance, and examining whether the EMS is effective. This study will further the knowledge of Defence environmental management practice, especially in a marine environment. It is expected to form systematic evaluation outcomes on SWBTA and provide stakeholders and environmental managers with references on day- to-day environmental management activities in this area, and other military sites in the future.

Coastal mud dynamics and their ecological-socio-economic impact

Li Li ([email protected]) PhDField of Study: Oceanography

Over the past 50 years both the large river catchments and coasts have been greatly modified by extensive human activities including dams and irrigation, land reclamation, and port construction. These rapid developments have altered both the flux of terrestrial materials to the sea, and their transport processes in the coastal ocean, resulting in distinct physical, chemical, and biological responses in the marine environment in the coastal oceans. Huanghe (yellow River), Changjiang (yangtze River) in China and Burdekin and Fitzroy Rivers in Queensland have been illustrative examples of such modifications, and the environmental issues have presented challenges to the social and economical development. This project aims: (1) to model sediment dynamics of muddy coasts and estuaries; (2) to examine the role of estuarine and coastal mud in preventing toxic/non-toxic algae blooms and sequestering nutrients and pollutants in turbid estuaries and coastal waters; and (3) to evaluate its socio-economic impact.

Sea ice in the Amundsen Sea.

Effects of ice shelf melting on Southern Ocean water formation

Darrell Terry ([email protected]) PhD (started Session 2 2009)Field of Study: Oceanography

One of the big unknowns in climate change is Antarctic ice shelf stability. The latest International Panel on Climate Change (IPCC) report projects a ~0.5 m sea level rise by 2099. However contributions of melting Antarctic ice were excluded, since they are poorly understood. Collapse of the ice shelves could increase sea level by 1-7 m, with the Amundsen Sea ice shelves alone contributing 1.5 m. Consequently, there is a growing contingent of scientists who believe that the IPCC report underestimates sea level rise by a factor of 2 or more. Due to the large quantity of freshwater tied up in Antarctic ice, rapid deglaciation resulting from ice shelf collapse not only increases sea level, but also freshens the waters of the Antarctic seas and Southern Ocean. This freshening impacts the thermohaline circulation, which in turn affects global climate and influences weather patterns. The Amundsen Sea ice shelves are melting rapidly, roughly 100 times faster than others in the Antarctic. Their rapid melting is believed to be driven by the ocean, with tides a primary mechanism for injecting warm water into the cavity under the ice shelves and inducing turbulent mixing through internal waves. Turbulent mixing influences both the melt rate and the spread of the resultant fresher water. The Circumpolar Deep Water (CDW), which supplies the heat for this process, has been observed

to be warming in recent decades. As the CDW warms, melting and mixing will accelerate.

This project will simulate the dynamics of ocean circulation in the Amundsen Sea using ROMS (Regional Ocean Model System), a well-developed ocean model. The primary goal is to determine amount of heat transferred from the ocean into the ice shelf and the associated melting both for present conditions and for warming CDW. The resulting changes in the salinity and temperature over the continental shelf will also be evaluated. The Amundsen Sea has been chosen as a study site, not only due to its rapid melting, but also due to the observational data available from a recent research expedition that Dr Robertson participated in. This data along with Quikscat satellite data will be used for model verification. The work in the Amundsen Sea extends a present honours student’s project. It is applicable to other Antarctic Seas, such as the Ross Sea, which is being investigated in collaboration with Mike Williams of NIWA (National Institute for Water and Atmospheric Research) in New Zealand. Dr Robertson is currently collaborating with NIWA providing modeling expertise and results and they provide observational data in return. The outcomes of this project will not only provide estimates of the heat fluxes into the ice shelves in the Amundsen Seas, but also a systematic way of evaluating the ocean’s contribution to ice shelf melting. This is a key step in addressing the “poorly understood” ice shelf processes for future IPCC evaluations of climate change.

Ensemble methods in oceanic modelling

Robert Woodham ([email protected]) PhDField of Study: Ocean modelling

This research project seeks to investigate the predictability of oceanic models, using a limited area model of the ocean, as well as ocean observational and forecast data from the BlUElink ocean forecasting system. The limited area model has been used to investigate a domain in the vicinity of Perth, and error growth in this domain has been studied by perturbing sea surface temperatures (SST), using Empirical Orthogonal Functions (EOFs). This enables the Jacobian matrix to be approximated with a relatively small number of model runs, and the most significant error patterns to be identified. More recently, data from the BlUElink system has been used to compute the average error growths, for a domain in the Tasman Sea, of three forecasting strategies: persistence, climatology and deterministic forecasts. This study indicates that SST is less predictable than Sea Surface Height (SSH), but surprisingly, the BlUElink system seems better able to predict SST than SSH. The latency of assimilated observations is identified as a major source of error in the deterministic forecasts. Furthermore, predictability is found to be highly flow-dependent, making the a priori selection of forecasting strategy problematic.

Estimate the social economic benefits of ocean observing system

Fan Zhang ([email protected]) PhDField of Study: Oceanography

The aim of my research are first to explore the relationship between NSW ocean observing system and potential benefit related sectors, then evaluate the social economic benefits that different users and public agencies could get from the information provided by NSW ocean observing system, and finally conduct the cost benefit analysis of NSW ocean observing system. For the beneficiaries analysis, I will focus on three related sectors: commercial fishery, tourism and natural hazard prediction.

Modelling dynamics of the East Australian Current and the subtropical mode water off the east coast of Australia

Vihang Bhatt ([email protected]) PhDField of Study: Oceanography

The East Australian Current (EAC) is the weakest and one of the most complex western boundary current. The complexity of the EAC not only generates special interest in numerical investigation of its seasonal variability under the influence of the atmospheric and oceanic forcing but also its influence on the water mass of the oceanic basin. Recent advances in the high performance computing (HPC) using parallel cluster computers have enabled oceanographers to resolve this problem up to a certain degree. Working in this direction, Commonwealth Scientific and Industrial Research Organization (CSIRO), Bureau of Meteorology (BoM) and Royal Australian Navy (RAN) setup global ocean general circulation model with special emphasis on Australian region on a parallel cluster computer under the Bluelink Reanalysis (BRAN) program. As a cross verification of BRAN data, high resolution ocean reanalysis from the OFES model (The Earth Simulator) has also been used. In this project, the high resolution data obtained from the BRAN and OFES has been used to meet the following objectives

• Investigate seasonal circulation on the East Australian Coast and the role of topographic and baroclinc forcing (JEBAR)

• Study the role of the East Australian current in heat balance in the region

• Examine the mode water formation in the East Australian coast and its seasonal and inter-annual variability

• Study model initialization errors using diagnostic and prognostic ocean model

• Investigate the role of thermohaline source and sinks in the diagnostic ocean circulation.

Modelling of the Yellow Sea circulation and sediment transport dynamics

Dehai Song ([email protected]) PhDField of Study: Oceanography

This project aims to develop and implement nested high-resolution models to study the inter-annual variability of the circulation and sediment transport dynamics in the yellow and East China Sea (yECS). The circulation models will be coupled with waves and tides, and incorporate data assimilation techniques. We will explore the major processes of the yellow and East China Sea inter-annual variability in temperature, salinity and the circulation patterns, using the state-of-the-art data analysis methods including the EOF analysis. Additionally, the remote sensing and the in-situ data will be used to calibrate/validate the numerical model results. The sediment transport model will be based on Wang (2002) and Wang and Pinardi (2002) and be coupled to the yellow Sea Circulation Model to simulate the sediment transport dynamics of the region. A particular focus of the sediment dynamics will be on the fate of the particulate matter discharged from the major rivers such as yellow and yangtze Rivers and their cross-shelf transport mechanisms.

The Advanced Materials group is actively engaged in the investigation of the properties and behaviour of materials with topics as diverse as:

• the phosphorus-in-silicon system as a potential basis for spin-based quantum computing

• fundamental properties of rare earth based intermetallics and compounds

• characterization of III-v semiconductors

• monitoring wear in prosthetic joints

• phase analysis of ore refining processes

• sediment transport in river basins and local forests.

In most instances, atomic or nuclear probes are used to study the microscopic properties of the materials involved or their spectroscopic “fingerprints” are used to identify and quantify the amounts of materials and phases present.

The key nuclear probe techniques employed include Mössbauer spectroscopy (57Fe as well as rare earth resonances such as 169Tm, 161Dy) and the very low temperature techniques of Nuclear Orientation (NO) and Nuclear magnetic Resonance on Oriented Nuclei (NMRON). Perturbed angular correlation (PAC) measurements are conducted in collaboration with Prof. Aidan Byrne of the ANU, who was closely associated with the development of the joint radioisotope implanter that is sited here at ADFA. Where radioactive nuclei are employed, they are either diffused into the specimens or implanted using the radioisotope implanter. Sometimes they are activated in situ via neutron irradiation at the lucas Heights reactor facility. The process of ion implantation is of interest in its own right and is investigated using our School’s radioisotope implanter as well as in collaboration with researchers at other facilities.

The in-house atomic probe technique is that of pulsed and swept-field electron spin resonance (ESR). Although this facility was designed specifically for the quantum computing project, it opens up exciting new possibilities for the study of other dilute magnetic systems.

These microscopic techniques are used in combination with x-ray and neutron powder diffraction, inelastic neutron scattering, specific heat, and bulk DC magnetisation and AC susceptibility measurements.

Current ResearchCharacterization of III-V semiconductors with ion beam analysis and radioisotope probes

Dr Heiko Timmers, with Dr S. Shrestha, Dr S. Butcher, Dr M. Wintrebert- Fouquet, Prof. A. Byrne, Prof. R. Vianden & Dr W. ZeitzThe increasing demand for wireless communications systems requires faster transistor operating speeds. For many applications, high power, high temperature operation is also needed. The fundamental physical properties of the group III-nitrides GaN and InN suggest that they should outperform Si, and also GaAs, in high-frequency applications. InN is expected to provide the highest operating frequencies while still at high power. In collaboration with Macquarie University in Sydney and others the growth of GaN and InN films is developed to achieve quality material for commercial applications. High precision analysis of the film composition is achieved using Elastic Recoil Detection (ERD) analysis. In addition, in order to study the role of defects and to test

important processing steps, radioisotopes are implanted into GaN and InN. The subsequent decay of these probes is then observed with Perturbed Angular Correlation (PAC) spectroscopy.

Elastic recoil detection analysis of materials

Dr Heiko Timmers with Prof. R. Elliman Elastic Recoil Detection (ERD) analysis is an ion beam analysis technique which enables the quantitative compositional depth profiling of materials and thin films. In contrast to Rutherford backscattering (RBS) spectrometry, with ERD analysis an individual depth-profile can be resolved for each chemical element. With very heavy ion projectile beams the sensitivity can be extended to span the periodic table. In order to improve the efficacy of ERD analysis, new design concepts for gas-ionisation detectors have been built and tested.

Fusion dynamics and scattering

Dr Heiko Timmers with Dr M. Dasgupta & Prof. D. Hinde The relative motion of two nuclei colliding at energies spanning the Coulomb barrier is coupled to other degrees of freedom of this binary system with the consequence that the binary system encounters a distribution of potential barriers rather than a single barrier. While barrier distributions can be probed in fusion experiments, it has been shown in this work that some information about the barrier distribution may also be obtained with measurements of quasi-elastic and elastic scattering. Experiments on the system 40Ca+96Zr suggest that multi-neutron transfer may play an important role in the fusion of heavy systems, as has long been postulated. Quasi-elastic scattering measurements are performed to test this postulate. The results are relevant to the laboratory synthesis of super heavy elements.

Magnetic properties and magnetocaloric effects

Emeritus Professor Stewart J. Campbell and Dr Jianli WangThe overall aim of this project is to investigate the magnetic and structural properties of a wide range of materials using techniques such as magnetization, Mössbauer spectroscopy and neutron diffraction. These projects are undertaken in collaboration with colleagues from Australia, Germany, Belgium and China. A particular emphasis is the search for suitable materials that exhibit giant magnetocaloric effects associated with field-induced and temperature-induced first order magnetic phase transitions. Current materials under investigation include:

• MnFeP12-xAsx –based compounds which offer pronounced magnetocaloric effects around room temperature.

• RMn2Ge2-xSix compounds. A giant magnetocaloric effect has been observed around TC(Nd) = 36 K for NdMn2Ge0.4Si1.6. This pronounced effect is associated with the field-induced first order phase transition from antiferromagnetic to ferromagnetic state due to the appearance of Nd magnetic ordering. Other properties of interest include the co-existence of antiferromagnetic and ferromagnetic states with R = Pr and valence transitions with R = yb, Eu.

• RNi2Mn (R=Tb, Dy, Ho, Er). Continuing interest focuses on resolving the crystal structure of these recently synthesized compounds and analyses of the magnetocaloric and critical exponent behaviour at the magnetic phase transitions (e.g. TC=147±2 K for TbNi2Mn).

• R2Fe17-xMnx. An invar-like effect evident around room temperature accounts for the non- monotonic composition dependence of the lattice parameters at room temperature in R2Fe17-xMnx compared with other R2Fe17-xMx systems (M=Al, Ga, Si) and the related R2Co17-xMnx series.

• Ni-Mn-Ga-type alloys exhibit enhanced shape memory effects on doping with small amounts of Co. In order to fully understand and exploit this promising behaviour, we aim to determine the magnetovolume effect at the phase transition temperature Tm and derive the magnetic contribution to thermal expansion. We are also exploring the relationship between magnetic state and nearest Mn neighboring distance in this continuing project.

Magnetic resonance program

Dr Wayne Hutchison, Dr Libu Alexander with Prof. Martin Brandt, Dr Jeff McCallum, Dr Greg Milford, Prof. Steven Prawer, Dr Paul Spizzirri & Dr Laurens Willems van Beveren The broad aim of this program is the use of magnetic resonance, directly, for measurements on spin systems which have application as spin based quantum computers (QC). The technique is also applied to investigations of the principal materials and fabrication processes. The emphasis is on electron spin resonance (ESR) studies of the phosphorus-in-silicon (Si:P) system:

Pulsed ESR for coherence time measurements

One of the attractions of a spin based quantum computer is the prospect of long coherence times. In this project, pulsed ESR is applied to ensembles of phosphorus spins in silicon to explore this experimentally. The spin coherence time is expected to increase with reduction in temperature and of the concentration of both the phosphorus donors and host 29Si isotope (non-zero nuclear spin). A pulsed ESR system has been developed that can operate in conjunction with an electro-magnet down to 4 K, or with a dilution refrigerator and superconducting solenoid magnet down to millikelvin (mK) temperatures.

Swept field ESR measurements

Conventional (swept field) ESR is also used to investigate large area Si:P implants (ensembles) produced via implantation of P+ and molecular P2

+ at the University of Melbourne. Focus continues on examination of various preparation methods with a view to maximise donor activation, as viewed by ESR, and to minimise unwanted charge traps, which are mostly associated with the implantation process itself. Poor donor activation has been observed when using low energy implantation into substrates with surface oxides and this is a non-trivial issue to resolve. So far there is a strong indication that donor electrons are being poached by traps when the donors are placed near to the surface (i.e. the donors are effectively compensated by interfacial traps). There are many approaches to improve the yield of low energy implants and ESR can be applied as a diagnostic.

Mechanochemical methods and nanostructured materials

properties. Most recently, this work has addressed iron oxides in collaboration with researchers at the Australian National University and, in particular, the structural and magnetic properties of nanoscale spinel ferrites (e.g. ZnFe2O4; MgFe2O4; NiFe2O4) in collaboration with the University of Braunschweig , Germany.

Mössbauer spectroscopy as a tool for monitoring ore refining processes

Assoc. Prof. Glen Stewart with Dr Randolph PaxWork in collaboration with Dr Randolph Pax of Downer EDI Mining, Mineral Technologies, exploits the phase analysis capability of 57Fe-Mössbauer spectroscopy, in combination with x-ray powder diffraction, for investigating minerals and mineral refining processes. Recent investigations included the reduction stage in the production of synthetic rutile from mineral sands and the processing of local porphyry Cu/Au deposits.

Nature and influence of the crystal field interaction at the rare earth site in intermetallic compounds

Assoc. Prof. Glen Stewart, Banchachit Saensunon & Dr Wayne Hutchison with Dr Paul Gubbens, Assoc. Prof. Hiko Nishimura & Prof. Dominic RyanBanchachit Saensunon’s thesis work is directed at the influence of the crystal field interaction in rare earth intermetallic compounds. The first part of this project extends a systematic investigation of the crystal field interaction for the isostructural series RT2Si2 (R = rare earth, T = Cu, Ni, Co, Fe) to include T = Mn and Cr. The nature of the crystal field interaction in intermetallic compounds is complicated by the presence of itinerant electrons and the purpose of his investigation is to compare how the methods of Mössbauer spectroscopy and inelastic neutron scattering cope with this. The second part of the thesis project is being conducted in collaboration with Wayne Hutchison and Hiko Nishimura and looks at the crystal field origins of intriguing magnetic behaviour of the intermetallic series RNiAl4.

Radioisotope tracing of sediment transport

Dr Heiko Timmers & Dr Wayne Hutchison with Assoc. Prof. Jacky Croke, Dr Chris Thompson & Dr J. Fernandez-Niello Sediment transport along rivers and creeks is an important environmental issue. In this work we have established measurement facilities in the School to quantify sediment transport using the radioisotopes Cs-137, Pb-210 and Be-7. Experiments in progress are relevant to the Fitzroy river basin and local ACT forest management.

Rare isotopes as tracers of prosthesis debris

Dr Heiko Timmers & Dr Laura Gladkis with Assoc. Prof. P. Smith, Dr J. Scarvell & Dr J. Fernandez-Niello.The incidence of knee replacement surgery in Australia (~ 30,000 per year) is rising annually by about 10%. The established bearing material for knee prostheses is ultrahigh molecular weight polyethylene (UHMWPE) which is superior to any other. However, particulate wear debris delaminating from the UHMWPE component causes an inflammatory reaction that breaks down the bone, unfastens the prosthesis and can result in severe pain. Due to increasing life expectancy, many patients need several surgical interventions over their lifetime. Knee replacement surgery costs typically $15,000, imposing a high annual burden of half a billion dollars on the Australian health budget. In this project, we

measure the dynamics of wear debris shedding from UHMWPE in knee prostheses with the unprecedented accuracy of rare isotope tracing and accelerator mass spectrometry.

Structural and magnetic properties of rare earth multiferroic manganites

Assoc. Prof. Glen Stewart & Hazar Salama with Prof. Hugh O’Neill, Assoc. Prof. Hiko Nishimura & Prof. Dominic RyanSo-called multi-ferroic compounds are of interest to researchers because they exhibit both ferroelectric order (spontaneous electric polarization accompanied by structural distortion) and antiferromagnetism (an ordered magnet structure with zero net magnetization). The interplay between the two effects could possibly be exploited in future magnetic storage devices. As part of her PhD project, Hazar Salama has used 57Fe- and 170yb-Mössbauer spectroscopy to investigate the local magnetic moments and crystal field interactions in both the hexagonal and orthorhombic phases of ytterbium manganite (ybMnO3). In the case of orthorhombic ybMnO3, an intriguing hysteresis effect has been observed in the temperature region immediately below its antiferromagnetic transition. This work has most recently been extended to the two phases of TmMnO3 employing 169Tm-Mössbauer spectroscopy.

Recent Research Highlights and Achievements

UHMW polyethylene sample prepared with the radioisotope probe Indium-111 at the Bonn radioisotope implanter. The study has shown that over 95% of the polyethylene wear debris is adsorbed onto the actuating wheel and only a small fraction is released to the lubricant.

Banchachit Saensunon and Glen Stewart met up with Paul Gubbens (a regular guest at the School of PEMS) at the Berlin Neutron Scattering Centre (BENSC) from 12-16 May 2008 to record inelastic neutron scattering measurements for two intermetallic compounds. The data formed a substantial part of Banchachit’s PhD thesis. After the measurements were completed, Banchachit continued on to the Delft Technical University where he met up with Paul Gubbens to discuss planned 166Er-Mössbauer spectroscopy measurements and presented a departmental seminar. The image below, with Banchachit standing on top of the “NEAT” time-of-flight neutron spectrometer in the BENSC neutron guide hall, shows just how large the instrument is. The large curved panel conceals an array of several hundred neutron detectors.

In addition to carrying out neutron scattering experiments on the high intensity (Wombat) and high resolution (Echidna) neutron diffractometers at OPAl, ANSTO, Stewart Campbell and Jianli Wang undertook a series of research projects using neutron instruments at the BENSC reactor, Berlin (October 2008) and the FRM-II reactor in Munich (May 2009). The particular projects involved Magnetic Phase Transitions in PrMn2Ge2-xSix and Magnetic Structures and Magnetovolume Effects in Ni-Mn-Co-Ga Shape Memory Alloys. Stewart extended his visit to Berlin to carry out neutron polarization analysis experiments at the Ill reactor, Grenoble France in November 2009. The Ill experiments on a series of nanostructured ZnFe2O4 materials were undertaken with Dr Shane Kennedy, ANSTO and Dr Michael Hofmann, Technical University Munich.

Jianli Wang regularly visits the Bragg Institute, ANSTO and the Institute of Superconductor and Electronic Materials, University of Wollongong to perform detailed characterization of magnetic and transport properties. Their 14 T and 9 T PPMS, 5 T SQUID and differential scanning calorimetry facilities (which together cover the temperature range 1.5 K to 700 K), extend significantly the ranges available at UNSW@ADFA for measurements of physical properties.

Muon spin relaxation studies of iron(II) spin crossover complexes

Emeritus Professor Stewart J. CampbellIron (II) spin crossover materials that exhibit a change from high-spin (S = 2) to low spin (S = 0) offer considerable potential for applications in the emerging fields of molecular electronics and nanotechnologies. A productive series of investigations of these compounds in collaboration with the Johannes Gutenberg-Universitaet, Mainz and the Université Catholique de louvain, Belgium has culminated in a review article published in Inorganica Chimica Acta.

Spin coherence studies using the low temperature, pulsed, electron spin resonance facility

Dr Wayne Hutchison & Dr Libu Alexander Measurements of spin coherence in phosphorus doped silicon are important in the context of quantum computing applications. Our pulsed ESR system, used in conjunction with a dilution refrigerator, is used to make such measurements down to millikelvin temperatures. Recently, using an isotopically enriched 28Si host together with low donor concentrations, coherence times in excess of 100 ms have been observed.

Student ResearchA study of the crystal field interaction for two rare earth intermetallic series

Banchachit Saensunon ([email protected]) PhDField of Study: Physics

The interplay between the crystal and magnetic exchange interaction in rare earth intermetallic is responsible for a range of subtle magnetic structure and bulk behaviour. In this project the RT2Si2 (R=rare earth, T=Transition metal) and RNiAl4 series are investigated using 169Tm Mössbauer spectroscopy and inelastic neutron scattering (INS). The INS measurements were conducted at the Berlin Neutron Scattering Centre, Germany. All of the specimens are prepared at UNSW@ADFA using an argon arc furnace and they are first characterized using x-ray powder diffraction, specific heat, and magnetization measurements.

Structural and magnetic properties of heavy rare earth manganites

Hazar Salama ([email protected]) PhDField of Study: Advanced Materials

The multi-ferroic properties of the heavy rare earth manganites, with the composition RMn03, are currently under intense scrutiny. These materials are both ferromagnetic and ferroelectric in the same phase, resulting in higher-order magnetoelectric effects and complex phase diagrams at low temperature. Hazar’s PhD project examines the transition of RMn03 R=yb, Tm from the orthorhombic perovskite (o) to the hexagonal (h) phase by high pressure synthesis, the structure and magnetic interactions of both orthorhombic (o) and hexagonal (h) phases and how this affects their magnetic properties. The techniques of 169Tm-, 170yb- and 57Fe- Mössbauer spectroscopy are used to investigate the local magnetic moments and crystal field interactions. The Mössbauer spectroscopy investigations are complemented by magnetic susceptibility and specific heat measurements.

Tracing wear debris pathways from joint prostheses using radioisotopes

Jake Warner ([email protected]) PhDField of Study: Physics

With over 600, 000 annual total knee replacement operations performed worldwide, the popular choice for the articulating component has been ultra-high molecular weight polyethylene (UHMWPE) due to its very low wear rate. However, polyethylene wear particles from knee and hip prostheses can cause harmful immunological responses, leading to bone resorption and potential loosening of the prosthesis. Due to this aseptic loosening of the prosthesis, revision surgery is required, assuming greater cost and risk for the patient. In order to investigate this wear process, commercial knee simulators are used to actuate against the prosthesis, producing wear debris from the UHMWPE surface. The UHMWPE has been labelled with radioisotope tracers, allowing the tracing of debris pathways. This tracing method will hopefully lead to a better understanding of the tribology of the knee prosthesis and the debris exchange processes, as well as the accumulation of wear debris at various locations in the joint system.

Research AgreementsAcademic exchange between UNSW@ADFA, School of PEMS and the University of Toyama, Graduate School of Science and Engineering. Prof. Katsuhiko Nishimura from the University of Toyama is a regular visitor to UNSW@ADFA. His long standing collaborative research work with Dr Wayne Hutchison and the Advanced Materials Group was the basis of an agreement for Academic exchange between UNSW@ADFA, School of PEMS and the University of Toyama, Graduate School of Science and Engineering. The agreement was instigated some 5 years ago and was recently renewed.

Joint agreement between UNSW and ANSTO. Dr Jianli Wang’s position as Bragg- UNSW@ADFA Research Fellow (initially for a 3 year term) is part of this joint agreement. The Bragg Institute, ANSTO is responsible for neutron scattering at Australia’s research reactor, OPAl, and aims to be an international leader in neutron beam and X-ray science. Jianli works with colleagues here in PEMS and at the Bragg Institute on developmental and theoretical aspects of modern condensed matter science, particularly magnetism.

Major Facilities• Radioisotope implanter (negative ion, 50-150 kev).

• Two 3He-4He dilution refrigerators (base temperatures of 6 mK) used as low temperature platforms for: nuclear magnetic resonance on oriented nuclei (NMRON); low temperature nuclear orientation (lTNO); pulsed electron spin resonance (ESR); source and absorber geometry Mössbauer spectroscopy.

• Suite of four 57Fe- and two 169Tm-Mössbauer spectrometers (three cryostats 2-300 K; furnaces 300-720 K).

• Pulsed and conventional electron spin resonance (ESR) facilities.

• Sample preparation laboratory (argon arc furnace, tube furnaces, basic glass-blowing facilities, diamond saws & spark cutting, polishing, fume cupboards, hydrogen loading apparatus).

• X-ray diffractometers, vibrating sample magnetometer (0-1 T, 8-300 K) and AC magnetic susceptometer (2-300 K).

• Radioisotope handling laboratory.

• Two new Perturbed Angular Correlation spectrometers at UNSW@ADFA.

In 2008-2009, the impressive suite of research apparatus located at PEMS was augmented through the donation of two spectrometers for perturbed angular correlation (PAC) research by the Hahn-Meitner Institute in Berlin. The gift was facilitated by Dr Wolf-Dietrich Zeitz. The spectrometers complement in particular the radioisotope implanter, which is the ideal preparation tool for PAC.

The method suits research into magnetic and semiconductor materials. During a five months visiting Fellowship, which has just ended, Dr Zeitz installed the PAC spectrometers and introduced his PEMS colleagues to their possibilities. The quick installation time was made possible through the effective support of the PEMS workshops. Moreover, as in a previous sojourn, Dr Zeitz proved to be a sought-after mentor of postgraduate students and postdocs contributing to tribology (the science and technology of interacting surfaces in relative motion, including the study of friction, lubrication, and wear) work on polyethylene, knee prosthesis wear research and magnetism in nickel. The PAC spectrometers play a particular role in collaborative work on the semiconductors GaN and ZnO which aims to contribute to the development of spintronics (the study of magnetic and electric fields produced by electron spin). This international collaboration involves apart from UNSW@ADFA researchers, scientists and facilities at the University of Bonn and the Australian National University.

The Astronomy & Astrophysics group contributes across a wide range of research areas, principally in stellar astronomy, aimed at the characterisation of stellar populations, study of the formation and evolution of stars and stellar systems, and investigation of the physical properties and chemistry of their circumstellar environments. There is a strong emphasis on a multi-wavelength approach to our research, with ground-based optical, IR and radio observations merged with satellite-based optical, IR and high-energy (Uv, gamma- and X-ray) observations and balloon-based X-ray data, to understand the objects and phenomenon that we observe in an astrophysical sense.

Current ResearchOur current research can be categorised into several broad themes:

High-energy astrophysics

Ravi Sood, Warrick LawsonContact: Ravi Sood

Satellite observations of X-ray accreting binary systems, and young magnetically-active T Tauri stars in star-forming regions, are obtained using current space observatories, e.g. Chandra or XMM/Newton, or from satellite data archives, e.g. ROSAT, ROSSI, etc. Ground-based observations are made using radio and optical/IR telescopes located in Australia (Coonabarabran and Narrabri) and overseas (la Silla, Chile or Sutherland, South Africa) to complement the X-ray data. Some observations are made as part of coordinated campaigns with other ground- and space observatories to determine the nature of the X-ray sources over a range of wavelengths, or their behaviour over an interval of time.

Star Formation

Warrick Lawson, Robert Smith, Garry Robinson, Chris Wright Contact: Warrick Lawson

We study the chemistry of star formation environments, both interstellar and circumstellar, and investigate the influence of moderating effects such as Uv photon radiation fields and stellar winds, principally by obtaining near- and mid-infrared spectroscopy of young stellar objects using ground-based telescopes and infrared space observatories. This work is complemented by laboratory studies of interstellar dust and ice analogues and numerical modeling. We study the properties of the stellar populations of star formation regions, e.g. magnetic activity in young stars and brown dwarfs, the prevalence of inner dust disks and the timescale of their dissipation or inclusion into proto-planetary grains, and the angular momentum history and dynamical state of young stellar clusters. This research is supported by data obtained with current space missions such as Chandra and the Spitzer Space Telescope.

Recent AchievementsOptical Telescope to monitor IO-Jupiter from Alice Springs

A collaborative programme between Ravi Sood and Prof. Hiroaki Misawa of the Planetary Plasma and Atmospheric Research Center, Tohoku University, Sendai, Japan, started in 2007 to observe the volcanic eruptions on Io, one of the moons of Jupiter, to investigate the effects that these eruptions will have on the ionosphere of Jupiter. Io is somewhat smaller than our Earth, and is the most active volcanic body in the whole Solar System.

The observations are carried out via an optical telescope specifically designed and built at Tohoku University for the project. The telescope is installed at the Balloon launching Station, Alice Springs. The site has been chosen because of the good viewing conditions available there. The telescope dome and some of the control systems were installed in early 2008. The telescope optical system was installed and commissioned during the period 3-16 June 2008.

The telescope has a 30 cm mirror, a CCD detector cooled to -75oC, and is configured as a Schmidt-Cassegrain (F10) system. It is equipped with very narrow band filters to cut out human made background light. The light transmitted by these filters will allow us to monitor sulphur ions (1 nm wide filter) and sodium atoms (2 nm wide filter) released from Io. The observations will last a period of up to five years.

Rob Smith and Chris Wright were allocated observing time on the Spitzer Space telescope in the most recent (5th) cycle of observations in February 2008 to investigate the ice and dust surrounding the Class I protostar, GGD30IR. The actual observations were, however, scheduled for the morning of May 14 2009. The observations were successfully obtained, but 24 hours later Spitzer ran out of superfluid helium and the cryogenic part of its mission ended, after 5 years and 9 months of operations.

Rob Smith and Chris Wright discovered a silhouette envelope around the Class I protostar, GGD30IR using mid-infrared data from the Spitzer Space Telescope GlIMPSE legacy programme. Silhouette envelopes are not often seen. Normally protostellar envelopes are investigated by millimeter/submillimetre observations but the Spitzer data provide the opportunity to investigate this envelope in the mid-infrared. Because the mid-infrared probes lower density material, this provides a rare opportunity to investigate the tenuous outer regions of the envelope. The figure below shows a Spitzer image of this envelope, silhouetted against 8 micron background emission.

8 micron (infrared) image of the protostar GGD30IR (Smith & Wright 2009, MNRAS, in press). The very bright source in the centre is the protostar and the dark areas on either side are the dusty envelope of the protostar silhouetted against the background emission. The image is taken from archival data from the GlIMPSE legacy Programme and was obtained with the Infrared Array Camera on the Spitzer Space Telescope which is operated by the Jet Propulsion laboratory, California Institute of Technology under a contract with NASA.

Rob Smith and Chris Wright, in collaboration with Steve Charnley and Martin Cordiner of the NASA Goddard Space Flight Center were allocated observing time on the Mopra Telescope near Coonabarabran as part of an astrochemistry project to search for anions and carbon chains in southern-hemisphere radio sources.

Warrick Lawson, in collaboration with colleagues at the Max Planck Institute for Astronomy, Heidelberg, Germany, has completed several studies of the prevalence and nature of protoplanetary disks in nearby young stellar populations, based on observations made with NASA’s Spitzer Space Telescope. The host stars of these disks have ages ranging from 1 to 15 million years. Amongst the low-mass stars in these populations, the disks are dominated by so-called ‘transitional disks’, which have largely evacuated inner disk regions and conventional circumstellar outer disks. The prevalence of these types of disks suggests that they do not occupy an evolutionary disk state, but may be the common disk geometry around low-mass young stars. Observations of protoplanetary disks offers a fascinating insight into conditions in the young solar nebula that resulted in the formation of our solar system. An example is the 8 million year old star RECX 5 in the ή Chamaeleontis star cluster discovered at UNSW@ADFA in 1999. The disk chemistry is remarkably abundant in the crystalline silicate forsterite. The Spitzer spectrum of the RECX 5 is almost identical to that of the pristine solar system comet Hale-Bopp, suggesting that conditions 4.5 billion years ago in the young Sun’s disk must have been very similar to that of the present day conditions is the disk of RECX 5.

Student ResearchCurrent student research programs are:

• Star formation in dark clouds

• Dust grain growth in the disks around young stars.

C.M. Wright co-supervised a successful PhD project by Dave lommen, who graduated in 2009 at leiden University in The Netherlands. Dave’s thesis was entitled “The first steps of planet formation: Studying grain growth with millimeter interferometers”. The quality and impact of Dave’s thesis research was recognized with a subsequent offer of a prestigious Bolton Fellowship at the Australia Telescope National Facility.

PhD Opportunities and ScholarshipsThe Astronomy & Astrophysics group has ongoing PhD opportunities in the area of star formation.

74 School of Physical, Environmental and Mathematical Sciences - Research Report 09/10

The lower atmosphere research group is active in the following two broad areas:

1. Radar Entomology and Insect Migration (Alistair Drake)

• The development of Insect Monitoring Radar (IMR) technology and of procedures for interpreting IMR observation data. Recent research has focused on extracting as much information as possible from the echo signals in order to discriminate between different target types (locusts, moths, bugs, etc.), and on developing summaries and representations of the IMR data that can be produced routinely and that are readily assimilated by users in pest-management (especially locust-control) organizations. Effort is now being redirected to modifications of the radar design aimed at extending its applicability and increasing the confidence with which targets can be identified, and to laboratory measurements of target radar characters to facilitate interpretation of the radar data. In addition to work with the School’s own IMRs, assistance is being given to two Chinese research groups currently establishing IMR capabilities.

• Improving understanding of locust migration in inland eastern Australia, and increasing the confidence with which locust migrations can be detected and forecast. This work draws on archival IMR datasets extending over several seasons, as well as continuing observations, and is being conducted in collaboration with entomologists and forecasters at the Australian Plague locust Commission. The datasets are also being explored for more general insights into insect migratory activity and its relation to weather, climate, and geography.

2. Monitoring the atmospheric boundary layer (Barbara Burns, David Low, John Taylor)

• The development of ground-based systems for acoustic and electromagnetic remote sensing of the atmospheric boundary layer and the utilization of these systems for understanding the mean and turbulent structure of the atmospheric boundary layer. A major focus is on the interaction between the boundary layer and mesoscale meteorological phenomena such as fronts, local wind systems and gravity waves. These problems are being approached in observational and modelling studies.

• Investigation of the initiation and subsequent organization of convection, and the propagation of convective lines, via a “complex systems” approach.

• The algorithmic extraction of useful parameters (temperature, moisture, turbulence, etc) from atmospheric echoes: the process of modelling what contributes to electromagnetic and acoustic echoes from the atmosphere, and separating the individual contributions from each other.

• Instrumental comparisons: how different sensors see the same parcel of air in different ways. In particular, how turbulence is seen by different instruments.

• Investigation of algorithms for extracting water depth from hyperspectral imagery of coastal waters.

Application of error analysis and sensitivity studies to determine error bars in algorithm extractions.

Current ResearchRadar entomology and insect migration

Alistair Drake, Haikou WangThe Insect Monitoring Radar at Bourke operated throughout 2008, with observations being accessed daily during the locust season by scientists at the Australian Plague locust Commission and used by them to develop forecasts of the locust situation and to plan survey patrols. The observations were also incorporated into the long-term dataset of seasonal insect movements for this site, and some improvements were made to the data-processing and analysis software. In late December 2008 the Bourke unit

was damaged by a windstorm. Most of its components were subsequently brought back to Canberra for repair (or replacement) and testing, and it is expected that the unit will be running again before the end of the year. At the same time, procurement and construction proceeded for an upgrade to incorporate current microcomputer technology and digital rather than analogue signal processing. As well as allowing existing units to be maintained in operation for several more years, the new design will make construction of additional units, if the need arises, relatively straightforward.

Alistair Drake has been drafting a monograph, co-authored with D.R. Reynolds (University of Greenwich, Chatham, UK), on radar entomology. He spent time with Dr Reynolds in Britain in both 2008 and 2009. While there he participated in a workshop on “drift” (of animals migrating in atmospheric and oceanic flows) at Rothamsted Research, Harpenden, UK.

Atmospheric boundary layer research

John Taylor, David Low, Barbara BurnsDuring 2008/2009 we ran two field experiments:

• Through May, June, July and August 2008 meteorological data was collected continuously from a High Frequency (HF) sodar, radio acoustic sounding system (RASS), ultrasonic anemometer and Automatic Weather Station (AWS) at the School of PEMS field site. In addition, during the morning, a digital camera automatically recorded images for visibility monitoring. This data set was used for Jamie Moogan’s Honours project on fog clearance modeling and for a model verification study of the meteorological component of the CSIRO atmospheric model TAPM (The Air Pollution Model).

• Starting in December 2008 and running through to the end of April 2009 we collected meteorological data from a sodar and an AWS located at the Molonglo Radio Telescope (University of Sydney), near Hoskinstown, NSW. Over the same period, data was also collected from a HF sodar and AWS at the School’s field site. This experiment was a major component of Kenn Batt’s PhD. Project on summertime easterly wind changes in the ACT region.

A sequence of images showing the clearance of a thick fog on the morning of 29th May 2009. Images times: 8:18, 8:24, 8:30, and 8:36 am EST. The images were captured by the visibility monitoring system at the PEMS field site and used in Jamie Moogan’s Honour’s project.

Student ResearchEvaluation of insect monitoring radar technology for monitoring locust migrations in inland Eastern Australia

Haikou Wang, PhD Thesis, 2008Abstract:

To evaluate the utility of insect monitoring radar (IMR) technology for long-term monitoring of insect migration, a mini-network of two IMR units in Bourke, NSW, and Thargomindah, Qld, and a base-station server in Canberra, ACT, was set up in eastern Australia. The IMR operated automatically every night under the control of a personal computer that also conducted data acquisition and processing. Digitisation of radar signals, their analysis (delimitation of echoes from background noise and adjoining echoes, followed by extraction of estimates for each target’s speed, displacement direction, body alignment, radar cross-section, and wingbeat frequency and modulation pattern), and generation of observation summaries were implemented as a fully automated procedure. Wingbeat frequency was found to be retrievable from the IMR’s rotary-beam signals, and this allowed each individual target to be characterised by its wingbeat as well as its size and shape. By drawing on ancillary information from the Australian Plague locust Commission’s database of field survey and light trap records, the echo characters indicative of Australian plague locust, Chortoicetes terminifera (Walker), were identified. Using these, about 140 nights with detectable plague locust migrations were identified for the Bourke IMR site during 1998-2001 and 31 nights for Thargomindah during 1999-2000. Analysis of these nights confirmed that C. terminifera migrates in association with disturbed weather, especially tropical troughs, in eastern Australia. Trajectory simulation based on IMR-derived displacement directions and flight speeds allowed the identification of population movements likely to reach favourable habitats and thus to develop rapidly and possibly cause a plague. The outbreak during 1999-2001 most likely originated from the southeastern agricultural belt after migrations and multiplications over several generations. The IMR observations demonstrated that C. terminifera migrates over long distances with the wind at night and indicated that it may have an orientation behaviour that prevents it from being taken too far into the arid inland, a trait that could be highly adaptive in this environment. The two IMRs were operational for more than 85% of scheduled time during the study period and provided a wealth of information of potential value for locust management and migration research.

Current ResearchInvesting in research in natural resource management

Stuart PearsonStuart Pearson, in his previous role as a research investor for the government agency land & Water Australia, provided research leadership and support on issues such as citizen science; periurban issues; endocrine disrupting chemicals; and resilience. He has an ongoing interest in achieving the transition of research into action.

Science EducationDrawing on his experience in monitoring and evaluation for the government agency land & Water Australia, he is coauthoring a paper on the triple bottom line analysis of impact of investing in research in natural resource management. Tracking research impact and learning how to improve the outcomes of science investment is very important and forms a key part of science education.

Stuart Pearson is co-convener of the Australian Association for Environmental Education Conference to be held 26-30 September 2010 in Canberra. This is a substantial green science because the Australian Association for Environmental Education is the premier professional association for those who work in the research and delivery of environmental or sustainability education. Its membership provides connection between government, education sectors and industry groups. Strong support from Department of the Environment, Water Heritage and the Arts, Australian National University, Canberra Institute of Technology and the ACT Government ensures this will be a landmark conference.

Modelling activities (Mathematics/Science) for school students in Years 9-12

Dr Peter McIntyreMany high-school textbooks are lacking in applications of Mathematics to problems that might interest students. This CD provides a wide range of such activities, based on the use of graphics calculators.

Physics education

Dr David LowCollation and evaluation of good practice in Physics service teaching. What makes for “good” service teaching? Are there common factors? Is it material, presentation, personnel, …? How important is continuity? Do student attitudes override staff attitudes? Do students think they get value from the physics component of their service teaching? Does a student’s attitude change over the course of their degree? Do graduates (graduands) look back on the physics service teaching with appreciation or horror? Why? What are staff attitudes towards service teaching?

Predicting university performance

Dr Joanne Chapman with Dr Steven BarryUniversity admissions in Australia are dictated primarily by entrance ranking scores (TER) based on all courses taken in secondary school. However, these are unreliable indicators of ability to do mathematically-based university courses. Differences in mathematical curricula between Australian states also complicate admissions for students moving interstate, especially with 19 or more different mathematical courses being offered in high schools across Australia. Our research compares student TER and performance in a diagnostic test, against their university grade at the end of one semester to find a better predictor than simple TER measures. Our research also looks at the difference in performance of students with the same level of ability in different courses.

Recent ResearchAcademic performance of officer cadets

E-learning for geography’s teaching and learning spaces

Julie Kesby with Dr Kenneth Lynch, Prof. Bob Bednarz, James Boxall, Assoc. Prof. Lex Chalmers, Dr Derek FranceThis project emanates from an (INlT) International Network for learning & Teaching Geography in Higher Education workshop held in Brisbane in 2006. Discussion by group participants at the workshop and via online media post the workshop led to the development of a paper which was published in early 2008 in the Journal of Geography in Higher Education examining e-learning technologies, best practices, and the versatility in the use of e-learning approaches available to teachers and learners of geography.

Environmental education delivery in secondary school and impact on universities

Stuart PearsonPearson, S., Honeywood, S. & Mitch O’Toole, M., 2005, Not yet learning for sustainability: the challenge of environmental education in a university, International Research in Geographical and Environmental Education, 14(3), 173–186.

This paper was nominated for the Biennial Award for Promoting Excellence in Teaching and learning 2007 in Journal of Geography in Higher Education 32(2), 161–166, May 2008. Although the paper did not win the award the judges commented that, “The paper by Pearson et al. (2005) provides a useful case study in considering how environmental education is delivered in Australia in secondary schools and how that impacts upon universities. It deals with an innovative and relevant subject and helps readers to understand how management policies can influence the learning experiences of students in unexpected ways.”

The international judging panel from Europe, North America, Australia, Asia and Africa also recognized the basis of scholarship, rigour of approach, originality, potential influence on practitioners and overall contribution to promotion of excellence in teaching and learning geography.

A follow-up paper is in development.

Misconceptions in tertiary science and engineering mathematics

Popular mathematics writing

Emeritus Prof. Colin PaskThis work looks at the trends in writing about using mathematics in magazines and books aimed at the non-expert reader. There are also links to the evolution of mathematics-teaching methods and relevant new results in cognitive science.

The reflective student

Dr Amy GriffinThis scholarship of teaching and learning research aims to develop and evaluate pedagogical methods through which we can encourage students to reflect more deeply upon what they are learning. In 2006, I worked on an international, comparative analysis of active learning pedagogies, which was published in early 2008 in the Journal of Geography in Higher Education.
