***** To join INSNA, visit http://www.insna.org ***** Indeed, following up on Jessica: Burt's concept of redundancy is a key mechanism for disengagement from a local network cluster and for the establishment of new ties to other network clusters. Burt -- Structural Holes Myself and others have studied long-term network dynamics resulting from such actions: Ryall & Sorenson (2007) in Management Science Buskens & van de Rijt (2008) in American Journal of Sociology Reagans & Zuckerman (2008) in Industrial & Corporate Change Kleinberg, Suri, Tardos & Wexler (2008) in ACM Proc EC08 And, again following Jessica, another mechanism is balance, namely if a cluster contains imbalances, severing some ties is a balancing strategy. Heider 1946, 1958 Cartwright & Harary 1956 Again, several studies have investigated the long-term network dynamics of balance: Hummon & Doreian (2003) Social Networks Antal et al (2005) in Phys Review E Kulakowsky et a. (2005) in Int Journ Mod Phys C Ludwig & Abell (2009) Journal of Math Soc Marvel et al. (2009) Phys Rev Letters Montgomery (2009) Journ of Math Soc Leskovec et al (2010) CHI2010 Szell et al.
