“…In a recent review of the literature, Decker, Melde, and Pyrooz (: 16) noted that social network analysis “offers a viable alternative” to traditional methods of studying gangs, “as it inherently focuses on the micro level of explanation.” Indeed, the approach has been employed successfully to address a variety of gang phenomena, such as intergang conflict and murder networks (Braga et al, ; Kennedy, Braga, Piehl, ; Kennedy, Piehl, Braga, ; Kennedy et al, ; Papachristos, ; Papachristos, Hureau, and Braga, ), linkages between gang social networks and physical space (Tita and Radil, ); relationships between ego‐centered social networks, gang membership, and delinquency (Fleisher and Krienert, ; Roman et al, ; see also Pyrooz, Sweeten, and Piquero, ); and the structure of gang member ties, including subgroups, boundaries, and paths of resource acquisition (Fleisher, ; Klein, ; Lien, ; McGloin, ; Papachristos, ). Unfortunately, lack of relational data at the group level has prevented analysis of the association between gang member behavior and cohesiveness in the structure of intragang friendship ties.…”
