  • ConnectednessDiffusion: the process of dissemination, the spread of an idea or innovation from its hearth (origin) to other areas.

    What slows/prevents diffusion?- time-distance decay- cultural barriers-transportation/communication barriers

  • Types of DiffusionExpansion Diffusion idea or innovation spreads outward from the hearth

    Contagious 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 adaptations

    Relocation Diffusion movement of individuals who carry an idea with them

  • BARRIERS TO DIFFUSIONTIME and DISTANCE DECAY farther from the source & the more time it takes, the less likely innovation adopted

    CULTURAL BARRIERS some practices, ideas, innovations are not acceptable/adoptable in a particular culture e.g. pork, alcohol, contraceptives

    PHYSICAL BARRIERS physical barriers on the surface may prohibit/inhibit adoption

  • Examples 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 idea

  • Other Types of DiffusionRelocation diffusion movement of individuals who carry an idea or innovation with them to a new, perhaps distant locale. Can include languages, religions, and ethnicities.Photo credit: A.B. MurphyPhoto credit: H.J. de BlijKenyaParis, France

  • Migrant Diffusion (a form of Relocation Diffusion)Migrant Diffusion is when an innovation originates and enjoys strong, but brief, adoption there. 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.
