Strong Ties in a Small World
van der Leij, Marco; Goyal, Sanjeev - 2006
In this paper we test the celebrated `Strength of weak ties' theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that weak ties...

Complex Network Phenomena in Telecommunication Systems
Schintler, Laura A.; Gorman, Sean P.; Reggiani, Aura; … - 2004
Many networks such as the Internet have been found to possess scale-free and small-world network properties reflected by so-called power law distributions. Scale-free properties evolve in large complex networks through self-organizing processes and more specifically, preferential attachment. New...

Network Measures in Civil Air Transport: A Case Study of Lufthansa
Reggiani, Aura; Signoretti, Sara; Nijkamp, Peter; … - 2009
Air transport networks have exhibited a trend towards complex dynamics in recent years. Using Lufthansa’s networks as an example, this paper aims to illustrate the relevance of various network indicators – such as connectivity and concentration – for the empirical analysis of airline...

International Migration: A Global Complex Network
Tranos, Emmanouil; Gheasi, Masood; Nijkamp, Peter - 2012
Migration has become a prominent research theme in geography and regional science and it has been approached from various methodological angles. Nonetheless, a common missing element in most migration studies is the lack of awareness of the overall network topology, which characterizes migration...
