This is an analytical approach I could consider using. It might be useful for Gill as well?
Social network theory holds that behaviour is affected more by the kinds of ties and networks in which people are involved than by the norms and attributes that individuals possess. It examines patterns of ties to see what patterns emerge from their interactions.
In social network terms, pairs maintain relations (such as working together or friendship) and ties (a bond between two people based on one or more relations). The more relations a pair maintains, and the more frequently or intensely they maintain them, the stronger or closer the tie.
Pair-level bonding contributes to the sense of belonging to a group that is necessary to sustain the group as an entity rather than as a set of individuals. Feelings of belonging and community lead to greater commitment of group efforts, greater co-operation and greater satisfaction with group efforts.
One measure of an individual’s place in a network is their centrality – how well they are positioned to receive and disseminate information to all other members of the network. A star has access to information circulating the entire network, can influence others and the flow of information. The other end of the scale is isolation. The isolate does not maintain connections and thus does not receive communications. They can be cut off from information or receive it late.
Centrality can be measured by counting the number of others with whom an actor maintains relations. Can also be measured by closeness – the distance from each person to each other person. Central actors are closer to all others than are other actors. This means they are more likely to hear information available on the network. A third measure is betweenness, the extent to which an actor is situated between others (so information must pass through them to get to others). These measures assume communication flow along the shortest path. You can gauge centrality in a more complex fashion by looking at all the routes information can take and weighting them.
Chidambaram and Bostrom (1997) reviewed the literature and suggested that a well-developed group is cohesive, manages conflict effectively, balances tasks and socio-emotional needs. A well developed group may be judged by its outcomes.
Groups do not emerge fully developed. They begin their association, develop, experience crises, attend to deadlines, execute their tasks and conclude their association. They get to know each other and their technologies over time, learning how to interact with each other and how to use technologies in an appropriate manner. They develop, defining and redefining their network structures.
