***** To join INSNA, visit http://www.insna.org ***** Hi I am just about to submit my PhD which concerns innovation diffusion concepts within a particular context. I have dabbled in SNA during the early stages of my work, using it now as a pilot study only as my approach to the questions i wanted to answer changed somewhat. However, i still have lots of raw data and intend to use it for future publications. With this said, i do have some knowledge of the difficulties of using SNA within the field regarding the study of innovation diffusion. I have a longitudinal and cross sectional research design using SNA, reference: Larsen, G. D (2003) Informal communication networks and the diffusion of innovaitons in UK construction projects, in Anumba, C. J. (ed) Innovative Developments in Architecture, Engineering and Construction, Mill Press, Loughborough, pp 503-514. Hope this helps, let me know if you need any more info.
