    • 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
