1 Basic Geographical Concepts
1st Unit of the AP Curriculum!!

2 Ways Geographers Gather Info.
1. Remote Sensing Pictures taken from above Earth’s crust (usually in satellites) A. GPS (Global Positioning System) Precise location Navigation primary purpose Surveillance? Used in GIS B. GIS (Geographic Information System) Super-accurate maps w/ diff. layers Used to study relationships b/t diff. data sets Google Earth Under Surveillance, discuss the competing national interests of protecting individual rights and maintaining a safe and secure country

3 Another GIS

4 ARC View GIS Food and Environment Atlas:
ArcGIS from ESRI, Featured Maps:

5 Ways to Collect Data cont.
2. Field Studies/Case studies 3. Census Data Taken every 10 yrs. in U.S. Capital Intensive – $6.5 billion Uses Reallocate House of Rep. #s Federal funding amounts Statistical information Problems: Corruption Undercounting of homeless People who move can be counted twice or not at all

6 Surveys 4. Surveys: Assume that it is biased! Types of bias
Questions to ask: Who paid for the survey? Who was surveyed and who wasn’t? How many were surveyed? +/- 3% accuracy How was the question phrased? Types of bias Under-coverage Non-response bias Leading questions Eco Footprint Survey

7 Places in Geography Name = toponymy Location
Variety of sources for naming places… Mianus, CT; Hooker Point, FL; Slickpoo, ID; Suckerville, ME; Hell, MI, TruthorConsequences, NM; Monkey’s Eyebrow, KY; Phuket, Thailand; Intercourse, PA Location Absolute location latitude/longitude Benefits of GPS NEVER changes (in your life time) Relative location Location determined by what is closest around you Demonstrates focal points of the people Constantly changing Site vs. Situation of place Site (New Orleans below sea level) Situation (New Orleans on the mouth of the Mississippi and Gulf of Mexico)

8 Regions What makes each place different? Types of regions
Cultural landscape = Combo of physical environment & human influences on earth (built environment.) Sauer What features in the cultural landscape are the same in almost every major urban area? Types of regions Formal (uniform region/homogeneous region) Functional (nodal region) Vernacular (cognitive region/perceptual region) Mental maps  demonstrate “activity space” How is your 24 hour day/7 day week different from the other gender? Mental Map of your house….., community (mall, house, school)

10 Scale Small scale vs. large scale
Global scale vs. local scale (Globalization vs. Glocalization) Scale is VERY important to geographers Globalization ideas, values, beliefs, cultural traits are becoming increasingly shared throughout the world as interconnectedness increases Local diversity There are differences that are maintained around the world between places/cultural groups no matter how much globalization spreads These forces often compete throughout the world Pop culture vs. Islam English lang vs. minority languages Global organization (U.N.) vs. individual countries (U.S.) VERY important theme throughout the course

11 Globalization and Glocalization Bangalore, India

12 Culture MANY definitions Cultural hierarchy:
The way a particular group of people live, what they practice in death, what they believe, what they value, how they dress… Cultural hierarchy: Cultural trait (most specific) Culture complex Culture system Culture region Cultural realm (least specific) Cultural hearth – origin of a particular cultural trait How does culture spread???

13 Acculturation Acculturation
Dominant culture forces traits on subjected peoples Dominant culture will take on traits of weaker culture Spanish/Aztecs Europeans/Africans Wife domesticating her Husband.

14 Assimilation Distinct cultures become indistinct
“3rd Generation Rule” (non-religious) Ex. Jeans are EVERYWHERE Ex. African business men dressing in suit and tie Ex. Can you pick out which people in the U.S. came from which European countries i.e Ireland? Italy? Germany? Handshakes in Asia or business cards?

15 Sequent Occupance Several different cultural groups have occupied that territory so you will see different layers in modern culture Several cultural landscapes evident Ex. Romans  Arabs  Spanish in Spain (Aqueducts  Mosques  Plaza Mayór) Baptist Churches with Star of David stained glass windows in Harlem, NY

16 Mt. Olive Baptist Church
Harlem, NY New Hope Baptist Church Washington Heights, NY

17 How do I understand Diffusion?

18 Spatial Interaction Movement of people, ideas, commodities within and among areas Examples? Truck hauling goods International telephone calls Immigration into the US

19 Expansion Relocation Two Types of Diffusion Stays strong in the core
Gets weaker in the core

20 Expansion Diffusion EXPANSION DIFFUSION
Spread of an innovation/idea … in such a way that the # of those influenced grows continuously larger, resulting in an expanding area of adoption. (de Blij/Murphy – 7th ed., page R-20)

21 Expansion Diffusion This occurs when an idea or trait spreads from one place to another.

22 Kinds of Expansion Diffusion
Hierarchal Diffusion – spread of an idea through an established structure usually from people or areas of power down to other people or areas Urban areas to other urban areas and then spread to surrounding areas Rap music High-end fashion trends Wealthy people to middle class to lower class Any technological invention

23 This is a map of the diffusion of _______?

24 Expansion Diffusion Contagious Diffusion – spread of an idea/trait/concept through a group of people or an area equally without regard to social class, economic position or position of power. Flu epidemic Gossip in school?? Your book says information on the web is Contagious… do you agree???

25 Diagram of Contagious Diffusion
‘A’ is a diagram of contagious diffusion. Notice virtually all ‘adopt.’ ‘B’ is a diagram of hierarchical diffusion. Notice the leapfrogging over some areas.

26 Expansion Diffusion Stimulus Diffusion – the spread of an underlying principle even though the new groups “remix” your idea OR Stimulus Diffusion - involves the transfer of an underlying concept or idea, without the specific accompanying traits due to some cultural or other barrier to the movement of the idea

27 Stimulus Diffusion ex. (Michael Ayres)
McDonald’s in India  “Maharaja Mac” Sesame Street  OVER 30 Countries have adopted principles of this show Coca Cola and its different tastes around the world                               

28 Maharajah Mac Bangalore, India, March, 2012
McDonald’s new menu in Thailand. McDonald’s commercials from a global perspective:

29 The World According to Sesame Street

30 RELOCATION DIFFUSION Sequential diffusion process in which the items being diffused are transmitted by their carrier agents as they evacuate the old areas and relocate to new ones. The most common form of relocation diffusion involves the spreading of innovations by a migrating population.

31 Relocation Diffusion This occurs when the people migrate and take their cultural attributes with them. De Blij pg. 28 vs. Rubenstein pg. 38

32 Relocation and Expansion – In Review
‘A’ is relocation diffusion as the person goes. ‘B’ is expansion diffusion as the idea/trait moves or transports.

33 AIDS and Relocation Diffusion
Some authors suggest AIDS diffuses through relocation diffusion. This is true by the fact that the diffusers “take” the disease with them. However, AIDS is not contracted by everyone in its path. More importantly, the pattern of AIDS diffusion is more classically hierarchal (and therefore expansion).

34 Migrant Diffusion (a form of Relocation Diffusion?)
Idea enjoys strong, (perhaps brief,) adoption in hearth Idea travels elsewhere (& thrives) Idea fades out back in the hearth Ex. Disco in Egypt Ex. “Baywatch” in Europe Ex. Communism Ex. Old cars

35 One more look…Wal-Mart as both ___________ and __________diffusion – WHY?

36 Diffusion of Wal-Mart, Target and Costco What type(s) of diffusion?
Interactive maps of the evolution of retail from Flowing Data: Wal-Mart: Target: Costco:

37 BARRIERS TO DIFFUSION CULTURAL BARRIERS PHYSICAL BARRIERS
Some practices, ideas, innovations are not acceptable/adoptable in a particular culture Cultural taboos e.g. pork, alcohol, contraceptives PHYSICAL BARRIERS Physical barriers on the surface may prohibit/inhibit adoption Not as relevant today b/c of technology TIME-DISTANCE DECAY Farther from the source & the more time it takes, the less likely innovation adopted (more likely the same trait will develop differently) Technology makes this less important “Friction of Distance” – Interaction and communication between 2 things declines the further away you get

38 Distance Decay Graph Learn to think about distance decay in a “spatial” context Think of distance decay in terms of an ‘x’ and ‘y’ axis

40 Random Thoughts on Diffusion
Expansion Diffusion Contagious does not necessarily have a not a specific pre-existing structure for transmission disease contagion is a prime example the spread of products from a forest fire(particles/gases/heat) dissipate from the source(the fire) throughout the adjacent atmosphere. Measurement system - System International (Metric)(meters/grams) has spread from Europe throughout the world except for the US(and a couple small countries) US retains its modification of the British Imperial system of measurement (miles/pounds) Hierarchical requires a pre-established structure to channel the flow ie 'chain of command' International Business hierarchy, National, Regional, Local Relocation Diffusion Movement of people and things Europeans moved to the Americas and brought their culture with them

45 Satellite Orbits! It’s all about TIME!!

46 More examples of Hierarchical Diffusion
AIDS is typically viewed as hierarchical because of its historically distinctive URBAN to URBAN diffusion pattern “Blackberries” have diffused hierarchically. Blackberries, though becoming cheaper, are too expensive for most consumers to buy; therefore diffusing hierarchically.
