Nca2006 Presentation Transcript

  • 1.
      • Sorin A. Matei
      • Purdue University
    Space: the stuff of communication
  • 2. Philosophical assumptions
    • Space is constructed
    • Space is social
    • Space is a set of relationally defined locations
    • Space is about vicinities and the communication processes they enable
      • Vicinity is that space defined by our communication practices
    A B C
  • 3. Space is of two kinds
  • 4. Space is of two kinds… Space is everywhere
  • 5. Research questions
    • If we analyze flows of exchanges between nations, should we expect an increasing alignment of nations that share same cultural/civilizational characteristics?
    • Do nations that speak the same language or have the same beliefs send more information to one another?
      • Explored in
      • Globalization and heterogenization: Cultural and civilizational clustering in telecommunicative space (1989–1999).
      • Telematics and Informatics Volume 23, Issue 4 , November 2006, Pages 316-331
  • 6. Data
    • 2 who-to-whom matrices—networks—of international telephony ties between 107/110 nations (80% world population) – 1989 – 1999
    • Data from ITU and Telegeography
    • Matrices define “telecommunicative neighbors”
      • Countries are neighbors of each other if they send at least 5% of their traffic to each other
      • 5% threshold is based on analysis of tie distribution
        • Logarithmic
        • A nation typically sends 80% of its outgoing traffic to 4 nations
        • These nations typically absorb between 5 to 90% of the traffic (average 35%), each
        • All the other nations (109) absorb under 5%
  • 7. Data cntd.
    • Node attributes:
      • cultural afilliation (linguistic): rated
      • civilizational affiliation (religious): percentage
    • 4 linguistic and 4 civilizational areals
      • English
      • French
      • Arabic
      • Spanish
    • Protestant
    • Catholic
    • Islamic
    • Buddhist-Hindu
  • 8. Statistical Analysis
    • Spatial correlation (Moran’s I)
      • Measures likelihood of countries that have high values on certain attributes to be surrounded by nations that are like them
  • 9. Global Moran’s I
    • Global version: what is the magnitude of spatial association in the entire dataset?
      • 0 - 1: Countries are systematically surrounded by nations with similar values on the key attribute
      • -1 - 0: Countries are systematically surrounded by nations with dissimilar values on the key attribute
      • 0: No association
  • 10. Results: Global values
    • Global Moran’s I values increase for all, except one areal, Arabic
    • Value increases are significant (t-test for paired samples), except for the Islamic areal
    • There is an increasing tendency of countries that are similar culturally or civilizationally to cluster together in telecommunicative space
  • 11. Discussion
    • Evidence for heterogenization
      • Nations more likely to be surrounded by their civilizational peers
  • 12. Conclusion
    • Space can be viewed as a set of communicative ties
    • These ties differ from geographic ties
    • We can use this paradigm for any other situation that involves a social and a physical network
