THE ADOLESCENTS ON THE INTERNET: A REFLECTION ON VIRTUAL

COMMUNITIESThis article presents partial results of a study conducted with some Orkut communities

formed by adolescents. It also wonders if virtual communities work as a space for

expression of singularities, contributing to the formation of reflective and critical

adolescents, or, rather, they serve to their segregation to the consumer market. Also, it

presents some data collected from the communities of Orkut and a reflection on this

research, based on social psychology, psychoanalysis, sociology and philosophy authors

that examine contemporary culture. Then it concludes that, despite the different uses of

social networking, there is in these communities the prevalence of a standardization of

speeches, images and social meanings, a segregationist logic that erases the singularities.

FROM BEDSIDE TO BLACKBOARD: THE BENEFITS OF TEACHING MOLECULAR

BIOLOGY WITHIN A MEDICAL CONTEXT

Courses in molecular biology are part of practically every degree program in medicine and

the life sciences. Historically, many basic discoveries in this field have resulted from

investigations by doctors into the nature of diseases. This essay suggests that medical

educators deliberately incorporate such material, whether historical or contemporaneous,

into their molecular and cell biology courses. An example of such usage, an early report of

the detection of bacteriophage activity on pathogenic bacteria, is discussed in detail. Such

an approach can potentially narrow the perceived gap between "basic" and "applied"

science. As medicine is so intimately and obviously linked with human welfare, this also

provides an avenue for educators to discuss issues of scientific integrity and ethics within a

"pure science" course.

THE GROWING IMPORTANCE OF DENTAL SERVICES IN RURAL AMERICA

As the science of medicine progresses, associations between good oral health and

improved health status are being documented. However, the data would suggest that

individuals in America's rural communities are experiencing dramatic health problems

because they are not receiving dental treatment. This article addresses the importance of

dental services in rural communities and highlights the importance of cooperation among

hospitals, individual clinical providers, community health care organizations, and

governmental entities. It will also discuss why there is a shortage in these rural areas and

how the shortage is affecting rural communities and will address some strategies for solving

this crisis. This research on the availability of dental care in rural communities will provide a

framework for community leaders, elected officials, and health care providers to collect and

analyze data to support future decision making in response to community health care

needs. Such decisions increase the quality and efficiency of health care services, thereby

safeguarding the health status of the population. This study found that the capability for

hospital-based dental care services is greater in urban communities, whereas rural

communities have significantly less capability for hospital dental care. This would support

the premise that the availability of dental services is inconsistent across the United States

and that dental care resources could be allocated to provide a consistent level of services

across the population. It also emphasizes the importance of building innovative

partnerships among local, state, and national organizations to ensure that an appropriate

level of dental care is available in rural America. The study has managerial implications on

meeting the demand for dental care in rural communities and policy implications on future

resource allocation.
