1300 Chapter 8 - Spatial Interaction

Spatial Interaction
  • Refers to the interdependence between geographic areas
    • Movement of people between places
    • Flow of goods from one region to another
    • Diffusion of ideas from a center of knowledge
  • The amount of spatial interaction is a function of the size of the interdependent populations and the distance between them
    • A Post-Industrial World collapses distance between places
    • Thus the amount of spatial interaction depends not on distance but on relationships between areas and populations

Distance Decay
  • The decline of an activity with (perceived) increasing distance from the point of origin.

Critical Distance
  • The perceived distance beyond which cost, effort, and/or means cause a reduction in our interaction.

Friction of Distance
  • A measure of the amount of distance decay on spatial interaction

Time-Distance
  • A measure of the cost or effort, in time, to complete a distance activity

Psychological Distance
  • Distance as perceived by the individual or group
  • Mental maps

Barriers to Interaction
  • Distance
    • Actual or perceived
  • Fiscal Cost
    • How much does it cost to bridge the distance
    • Internet connections, airline tickets, fuel prices, etc…
  • Physical Environment
    • Cost in time, perception, and effort
  • Culture
    • Language, Government interference, beliefs, etc…
  • Psychological
    • Maintenance of privacy, prejudices, familiarity, etc…
  • Technological
    • Incompatible systems, absence of proper technology or education

Innovation
  • More people with more interaction increases the rate of innovation
  • Cities as foci of innovation
  • Communication technology as an enabler of innovation
  • Cultural and Governmental openness to interaction and communication

Biased Innovation
  • When innovation spreads in relation to social context as opposed to spatial context
  • Innovations which are less accessible to certain genders, races, social classes, or ages.
    • Unable to afford it or have the education to access or understand it

Individual Activity Space
  • Territoriality
    • The attachment to and defence of home ground
    • Nation States, gang territory, psychological space, etc…
  • Activity Space
    • The areas through which people move while conducting their regular activities
    • Generally a shared space
    • Defined by “trips”

Variables of Activity Space
  • Life stage
    • Determined by membership within an age group
    • Preschool, School age, Young Adult, Adult, Elderly
  • Mobility
    • The actual ability to travel
    • Access to technology
    • Cost
  • Opportunities
    • Perceived and actual

Spatial Diffusion
  • The process by which a concept, practice, or substance spreads from its point of origin to new areas
  • Concept
    • Idea or invention – memes
  • Practice
    • A process or action
  • Substance
    • A tangible object or thing
Relocation Diffusion
  • Items being diffused leave their original area and move to new areas
    • People moving from one area to another, taking their culture with them
Expansion Diffusion
  • Items being diffused spread geographically by spreading from one person/area to another person/area while remaining with the original person.
    • Disease is an example of this as are most concepts and ideas
Contagious Diffusion
  • People and places closest to the origin will be affected first while the farther away you area the longer it takes for the item to reach you.
    • Disease
Hierarchical Diffusion
  • Spread of items follows a hierarchical pattern of distribution
    • From large urban centers, to smaller cities, to towns
    • Up or down a ruling hierarchy

Spatial Interaction and Technology
  • Transportation Innovations – movement of people
    • Automobiles and freeways
    • Air travel
  • Communication Innovations – movement of information
    • Reliable mail
    • Telecommunications – internet and satellites

Migration
  • Relocation of place of residence and activity space
  • Intercontinental and Interregional
    • Abstract and mostly useless concepts as explained by the book
    • Can generally be seen as people moving from a home area to a completely different nation and continent
    • European migration to the Americas
  • Intraregional
    • Migration within a region – generally within a nation or state
    • Relocation for jobs within a country
    • New Orleans residents following Katrina
  • Forced or Involuntary migration
    • People are forced to move without their consent
  • Reluctant migration
    • When people have a choice but not a desire to move
  • Voluntary migration
    • When people make a positive choice to move

Incentives to Migrate
  • Push Factors
    • Negative conditions at origin
  • Pull Factors
    • Positive attractions of destination
  • Economic Factors
    • Single most important incentive
  • Political Factors
    • War, government oppression
  • Cultural Factors
    • Generally only affect direction of migration/determine end point
  • Amenities
    • Similar to cultural variables, importance increases with immigrant’s wealth and status

Place Utility
  • The value that an individual puts on a given residential site
    • Social, economic, and environmental perceptions
  • Step Migration
    • An eventual long-distance migration taken in smaller increments

Patterns of Migration
  • Migration Field
    • An area that dominates a locals in- and out- migration patterns.
    • Tend to be large nations/states and large urban areas
  • Channelized Migration
    • The tendency for migration to flow between areas that are socially and economically allied by past migration patterns, economic trade considerations, or by some other affinity (Chain Migration)
  • Return or Counter-migration
    • The return of migrants to their points of origin or elsewhere
  • Hierarchical Migration
    • The tendency for migrants to move from a smaller to a larger site
    • Urbanization
    • Effects of Post-Industrial Societies on direction

Laws of Migration (Expanded from E. G. Ravenstein – 1885)
Here is a summary of the laws in simple language.
  • Most migrants only go a short distance
  • Longer distance migration favors big-city destinations.
  • Large cities are migrant magnets.
  • Most migration proceeds step by step.
  • Most migration is rural to urban.
  • Each migration flow produces a counterflow.
  • Most migrants are adults; families are less likely to make international moves.
  • Most international migrants are young males.
  • Nations with long and/or open borders are attractive to migrants

World Systems Theory (Immanuel Wallerstein)
  • A world-system is any historical social system of interdependent parts that form a bounded structure and operate according to distinct rules, or "a unit with a single division of labor and multiple cultural systems" (1974a: 390).
    • mini-systems,
    • world empires, and
    • world-economies.
  • The modern world-system is a world-economy: it is "larger than any juridically defined political unit" and "the basic linkage between its parts is economic"
  • Origin in the European world-economy created in the late-fifteenth and early-sixteenth century (1974b: 15), but only consolidated in its current form by the mid-seventeenth century (1974a: 401).
  • The crisis of feudalism created strong motivation to seek new markets and resources;
    • Technology gave Europeans a solid base for exploration (1974b: 39).
  • North Western Europeans exploited initially small differences, via specialization in activities central to world commerce, to ultimately large advantage.
Strong Core-Periphery Structure
  • Core Areas
    • First World Nations (Western Europe, North America, some Asian nations)
    • Maintain position through economic and military power
    • Serve the interests of the economically powerful
    • Maintain economic stability
    • Maintain dependence of periphery areas
  • Semi-Periphery States
    • Second World nations
    • Help to maintain Core power
    • Deflect ire of periphery nations from Core nations
    • Provide different services and markets than periphery areas
  • Core power is maintained through a shared ideology and national myth
    • Currently it is the ideology of capitalism and liberalism which is the global geo-culture
  • Labor and production are spread across the three zones differentially
Change
  • Cyclical crises follow periods of innovation and expansion with periods of recession and stagnation.
  • Shifts in the power of the Hegemonic states
    • China, India, United States, England, Netherlands, etc…
    • Periods of clear leadership alternate with struggle (as now)
  • Resistance movements and ideology offer alternatives and variations
    • Socialism and anti-globalization movements
Current Situation
  • US Hegemony in decline since about 1970
  • In a period of crisis and change
  • Both capitalism and liberalism are exhausted as forms of international myth
  • Struggles against the ideas of global capitalism and liberalism
