Epidemiological Transition Model
Ravenstein's Laws of Migration
Said most people migrate for economic reasons, others for cultural reasons and/or environmental reasons; said there is an inverse relationship between number of migrants and distance traveled
A model that holds that the potential use of a service at a particular location is directly related to the number of people in a location and inversely related to the distance people must travel to reach the service.
Weber's Least Cost Theory
Industries will locate where three things can be done. These things being: minimize transportation costs, minimize labor costs, maximize agglomeration. Emphasises on cheap, cheap, cheap. With low production prices will result in high profit margins. The agglomeration keeps buisnesses competative as well as adds conviency to the consumer.
Wallerstein's Core-Periphery Model
A model of the spatial structure of an economic system in which underdeveloped or declining peripheral areas are defined with respect to their dependence on a dominating core region
New International Division of Labor
Transfer of some types of jobs, especially those requiring low-paid less skilled workers, from more developed to less developed countries.
Nicholas Spykman's theory that the domination of the coastal fringes of Eurasia would provide the base for world conquest.
The view that states resemble biological organisms with life cycles that include stages of youth, maturity, and old age.
Von Thunen Model
An agricultural model that spatially describes agricultural activity in terms of rent. Activities that require intensive cultivation and cannot be transported over great distances pay higher rent to be close to the market. Conversely, activities that are more extensive , with goods that are easy to transport, are located farther from the market where rent is less.
Central Place Theory
A theory that explains the distribution of services, based on the fact that settlements serve as centers of market areas for services; larger settlements are fewer and farther apart than smaller settlements and provide services for a larger number of people who are willing to travel farther.
Concentric Zone Model
A model of the internal structure of cities in which social groups are spatially arranged in a series of rings.
A model of the internal structure of cities in which social groups are arranged around a series of sectors, or wedges, radiating out from the central business district (CBD).
Multiple Nuclei Model
A model of the internal structure of cities in which social groups are arranged around a collection of nodes of activities.
Urban Realms Model
a simplified description of urban land use, especially descriptive of the modern North American city. it features a number of dispersed, peripheral centers of dynamic commercial and industrial activity linked by sophisticated urban transportation networks.
A model of North American urban areas consisting of an inner city surrounded by large suburban residential and business areas tied together by a beltway or ring road.
African City Model
Africa has the world's lowest levels of urbanization yet the most fastest growing cities. African cities have a high range of diversity so formulating a model is difficult
Latin American City Model
Griffin-Ford model. Developed by Ernst Griffin and Larry Ford. Blends traditional Latin American culture with the forces of globalization. The CBD is dominant; it is divided into a market sector and a modern high-rise sector. The elite residential sector is on the extension of the CBD in the "spine". The end of the spine of elite residency is the "mall" with high-priced residencies. The further out, less wealthy it gets.
Southeast Asian City Model
McGee model. Developed by T.G McGee. The focal point of the city is the colonial port zone combined with the large commercial district that surrounds it. McGee found no formal CBD but found seperate clusters of elements of the CBD surrounding the port zone: the government zone, the Western commercial zone, the alien commercial zone, and the mixed land-use zone with misc. economic activities.
