I'm looking for references that describe the structures of these three basic types from macro-perspective (not from the ego's point of view). How these networks differ from each other when described with the very basic network measures (centrality, betweennes etc.)? Which network measures suit the best to describe the structures of these three networks? The reason why I'm asking is that I have a small (n=89) socio-metric dataset where people working in the organization have rated the frequency of communication with every people in the same firm from three perspectives (routine work, development work and ideas). The hypotheses I have come up so far are: 1) Described with network measures, the network of information flow related to routine work tasks is likely to resemble centralized network structure. 2) Described with network measures, the network of information flow related to development work is likely to resemble distributed network structure. 3) Described with network measures, the network of information flow related to ideas is likely to resemble decentralized network structure. I decided to look at the data from socio-centric perspective first. I have not made any ego-centric hypotheses yet (although that would be interesting too, are the same individuals central in routine work and ideas and why/why not, for example). I have a conference paper about these socio-centric hypotheses that I can send in case someone is interested.
