Document Summary
Ullman"s conceptual model of interaction flows for commodities. Complementarity: one place has what another wants. Transferability: acceptable costs of exchange (on your own time: reefer madness) Intervening opportunity: if something is available closer, interactions with farther locations occur less often. Approaches to the study of spatial behavior and interaction. Three domains of spatial interaction in human geography: human travel and mobility, material/ energy transport, communication. International migration, internal migration, travel, undocumented migration, human trafficking, shopping, commuting, leisure travel . Physical- actual barriers in space (can slow, block, or redirect spatial interaction: distance, country borders, mountains, rivers. Sociocultural (modified distance decay: language, culture, race or ethnicity, cultural practices. Hierarchy of nodes- not all nodes are equal: more important places attract more interaction (i. e. are more accessible, and vice versa, e. g. , bigger cities have bigger airports. Space time compression is an important part of globalization.
