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

Space is of two kinds

Space is of two kinds… Space is everywhere

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?

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?

Globalization and heterogenization: Cultural and civilizational clustering in telecommunicative space (1989–1999).

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%

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%

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

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

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

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

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

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

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

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

Discussion Evidence for heterogenization Nations more likely to be surrounded by their civilizational peers

Evidence for heterogenization

Nations more likely to be surrounded by their civilizational peers

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

Space can be viewed as a set of communicative ties

These ties differ from geographic ties
