Diffusion WHY ARE DIFFERENT PLACES SIMILAR?

Objectives �Today we will be able to analyze the main types of diffusion to gain a better sense of why different places around the world share similar characteristics.

Diffusion Defined � The process by which a characteristic spreads across space from one place to another over time. Origination location of an innovation is called the hearth Technology influences speed of diffusion from hearth � Example – Cultural, political and economic features of the US traced back to hearths in Europe and the Middle East

Relocation Diffusion �The spread of an idea through physical movement of people from one place to another. When people move, they carry culture with them. � Language in the Americas https: //www. youtube. com /watch? v=4 g. Ih. Rk. Cc. D 4 U

Expansion Diffusion �The spread of a feature from one place to another in a snowballing process. �Three types of expansion diffusion Hierarchical diffusion Contagious diffusion Stimulus diffusion

Hierarchical Diffusion �The spread of an idea from persons or nodes of authority or power to other persons or places. Ideas spread from political leaders, the social elite, etc. . Ideas spread from nodes of power, such as large urban centers to rural communities � Hip-hop https: //www. youtube. com /watch? v=UOac. UWj. Hgi. E

Contagious Diffusion �The rapid, widespread diffusion of a characteristic throughout the population. When innovations spread like a disease; very fast without regard to hierarchy or the permanent relocation of people � Example – Ideas stemming from the world wide web… when things go viral.

Stimulus Diffusion �The spread of an underlying principle of something even though a characteristic itself apparently fails to diffuse. The computer mouse Fast food in other countries

Economic and Cultural Diffusion �The spread of economic systems and culture from nodes or hearths of origin to other regions. �Spread rapidly through tech advances �Three hearths: North America, Western Europe, and Japan to the “periphery”
