Daily Reading and Response
Read pp. 58-73, Respond to the following for Thursday
Discuss (with examples) the following terms in relation to the title of this chapter, Spatial
Interaction and Spatial Behavior. Remember, it is not enough to merely cite a definition.
We must understand how the terms apply to spatial interaction.
Spatial Interaction
Ullman’s model of spatial interaction
Complimentarity
Transferability
Intervening Opportunity
How might Ullman’s model help us understand the global trade in petroleum?
What is the problem with focusing on “aggregate, not individual” behavior? (Fellman, 60)
Friction of distance and the retarding effect of distance on human interaction
Distance Decay
Why is the “inverse square” relationship difficult to apply to human spatial interaction?
Explain Carey’s Gravity Model. How does it differ from Ullman’s model of spatial interaction?
How is Reilly’s law of retail gravitation related to the gravity model?
What problem with distance decay and gravitational pull models does the Potential Model attempt to
address?
Movement Bias
Distance bias
Direction bias
Network bias
Circulation Mobility
Migration Mobility
Explain how an individual’s activity space is determined by :
Stage of life
Mobility
Opportunities (how is awareness space related to opportunities?)
How is the development of infrastructure within a country related to the concept of the space-time
prism?
Why/how does the “tyranny of time” appear to effect women differently than men?
Explain the concept of critical distance in relation to distance decay.
Personal communication field
Place Perception
Environment Perception
