What slows/prevents diffusion?- time-distance decay- cultural barriers-transportation/communication barriersTypes of DiffusionExpansion Diffusion idea or innovation spreads outward from the hearthContagious widespread to most peopleHierarchical spread of idea from nodes of authority or power to other people or placesStimulus spread of underlying principal but with some adaptationsRelocation Diffusion movement of individuals who carry an idea with themBARRIERS TO DIFFUSIONTIME and DISTANCE DECAY farther from the source & the more time it takes, the less likely innovation adoptedCULTURAL BARRIERS some practices, ideas, innovations are not acceptable/adoptable in a particular culture e.g. pork, alcohol, contraceptivesPHYSICAL BARRIERS physical barriers on the surface may prohibit/inhibit adoptionExamples of Hierarchical DiffusionAIDS is typically viewed as hierarchical because if its historically distinctive URBAN to URBAN diffusion patternPolitical ideasFashion is also viewed as hierarchical. Why?Expansion DiffusionStimulus Diffusion the spread of an underlying principle even though the characteristic itself does not spread.ORStimulus Diffusion - involves the transfer of an underlying concept or idea, without the specific accompanying traits due to some cultural or other barrier to the movement of the ideaOther Types of DiffusionRelocation diffusion movement of individuals who carry an idea or innovation with them to a new, perhaps distant locale.

The innovation may travel long distances (& be thriving), but could be faded out back at the point of origination e.g. influenza in China will reach the U.S., but the epidemic could be over in China by the time it takes hold in the U.S.
