“…As such, affiliation networks must be seen as twomode networks rather than the more traditional one-mode network of dyads normally examined with social network analysis. These dual networks have been used in describing corporate interlocks between firms (Barnes & Ritter, 2001;Burris, 1991;Burt, 1980 and1983;Davis, 1991;Mizruchi, 1996); trustee interlocks in higher education (Ingram, 1995;Pusser et al, 2006); urban regimes (De Socio, 2007); and social capital and community economic development (Crowe, 2007). Key in each of these studies is the manner in which information, trust, and norms are built up via inter-organisational co-operation and information sharing across firms, organisations, and social groups, with the aim of building "relationships and common ways of working ... to achieve [a] policy goal" (Rydin & Holman, 2004, page 121).…”
