Demographic Transition Model (Demographic momentum: population continues to grow even after fertility rate decreases)
15
What model deals with disease vulnerability shifts in the DTM?
Epidemiological Transition Model (pestilence and famine, disease caused by overcrowding, diseases associated with longer life (cancer)
15
Explain the gravity model.
Further away, the weaker the pull (migration). Further away, less likely to interact.
15
Explain Zelinsky Model of Migration Transition.
Migration follows DTM stages. More mobile with industrialization. International migration in stage 2 (moving to 3-4). Stage 4 has intraregional, less emigration
15
Ravenstein's Law of Migration
Bad things push people out / good things pull people in. Econ (chief reason for migration). Most go short distance. Farther go to cities.Rural move over urban
15
Explain the Von Thunen model.
Answers will vary.
15
Alfred Weber's Least Cost Theory
Predicts where industries will locate (cost analysis of transport., labor, other factors). Minimize cost and maximize profits
15
Locational Interdependence
Hotelling's theory (location choices are influenced by location of chief competitors / related industries
15
Rostow's States of Economic Development
All develop in 5 stages. Investment allows nation to grow, which sparks economic gain that diffuses the nation. Based on NA / WEU (drawbacks for world)
15
What is this?
Borchert's Model of Urban Evolution
15
Central Place Theory (Christaller)
Explains /predicts patterns of urban places. Hexagonal patterns (cities, villages, towns, and hamlets)
15
Concentric Zone Urban Land Use Model (Burgess Model)
Explain / predict growth patterns of NA urban areas.As city grows, new rings are added and old ones change (CBD and peak land value)
15
Bid-Rent Curve
Variations in rent people are willing to pay for land at different distances from a peak point of accessibility / visibility to the CBD. More distance=less cost
15
Sector Model (Hoyt)
NA urban growth patterns. Similar land uses / socioeconomic groups cluster in linear sectors moving outward from a CBD (on transport corridors)
15
Multiple-Nuclei Model (Chauncy Harris and Edward Ullman)
Changing growth pattern is based on assumption that growth occurs independently around several major nodes (many are far away from the CBD)
15
Urban Realms Model (James Vance)
Explain / predict changing urban growth as cars became more prevalent and large urban "realms" developed (tied to mini-CBDs independent of CBD)
