  1. Spatial Interaction

  2. Connections between places

  3. Space-Time Compression • The time it takes for something to reach another place is getting shorter • Promotes rapid changes • Spreads cultural and economic ideas much more quickly • Ex. Cross-continental travel It’s a Small World…and getting smaller.

  4. Spatial Interaction • Only possible by physical travel in the past • Today, people can interact in many forms • Facebook • Teleconference • Limits potential for ‘distance decay’ • Groups far apart were unlikely to interact in the past. http://www.sparkminute.com/wp-content/uploads/2009/09/podcast-money-elsie-escobar22.jpg

  5. Diffusion • Process by which something spreads across space from one place to another over time • Ex. – inventions, ideas, values • Hearth – The place from which an innovation originates Spread of cell phone usage, 1980-2010

  6. Relocation Diffusion • Spread of an idea through the physical movement of people from one place to another • Usually for political or economic reasons • Newcomers bring their culture with them (language, religion…)

  7. Expansion Diffusion • The spread of a feature from one place to another in a ‘snowballing process’ • Three kinds of expansion diffusion: • Hierarchical diffusion • Contagious diffusion • Stimulus diffusion http://people-equation.com/wp-content/uploads/snowball_iStock_000007725565XSmall.jpg http://people-equation.com/wp-content/uploads/snowball_iStock_000007725565XSmall.jpg

  8. Hierarchical Diffusion • Hierarchical • Ideas or trends are spread by persons of power or influence • Ex. Trends in fashion often start in NYC, Paris, or Milan and spread to the rest of the world.

  9. Contagious Diffusion • Contagious • Widespread diffusion throughout the population • The farther you are from the source, the later you are impacted • Ex: Spread of communicable diseases • Ex1: Students will talk with slang well before it reaches the teachers.

  10. Stimulus Diffusion • Stimulus • Spread of an underlying principle (ex. computer mouse) • Mac and Windows were about the same until Windows used the mouse, then it spread faster.

  11. Cultural and Economic Diffusion • Core regions - North America, Western Europe, Japan • Peripheral regions – most of Asia, Africa, Latin America • Uneven Development • Increasing gap in economic conditions between regions of the world (core vs. periphery) • Result of a global economy
