You may also study institutional, country, and regional leval collaboration patterns, and much more..it is basic kind of analysis and may provide some clues. You can easily do it using UCINet, Pajek, or NodeXL, etc. Thanks Khan On Mar 3, 2012 12:41 AM, "tejashwini" <[log in to unmask]> wrote: _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
