***** To join INSNA, visit http://www.insna.org ***** I am completing a grant application in which I diffuse an intervention through key players in an adolescent friendship network. My external reviewer, who has some, but not a great deal, of SNA experience, asked if I could estimate the ratio of key players to the size of the network. I was not able to answer that, and my hunch is one can't, because it is so dependent on the network characteristics. However, I thought I would ask the members of SocNet for any input. Thanks in advance! Naja E.
