***** To join INSNA, visit http://www.insna.org ***** Hi - The node-connectivity / cohesive blocking approach that Doug White and I have proposed similarly allows overlapping structure, so it's not a complete "blind spot"; and does so in a way where the overlap structure can be formally explicated. See: http://www2.asanet.org/journals/ASRFeb03MoodyWhite.pdf . The advantage of node-connectivity for understanding social cohesion is the clear link between diffusion-through-multiple paths and higher-orders of k-connectivity.

We used the Clique Percolation Method: http://angel.elte.hu/cfinder/ that yielded interesting theoretical benefits to specify the significance of structural folding (the overlapping of groups) for entrepreneurial recombination and generative tension. Business groups do tend to overlap a lot, and overlapping groups are better performing, but more unstable. Needless to say, you need a historical dataset to understand what cohesion means (as Simmel, Moreno, and the early theoretical school of network ties clearly saw). http://www.personal.ceu.hu/staff/Balazs_Vedres/papers/vedres.stark.folds.pdf This article appears in the January issue of AJS. _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
