摘要:Social network analysis (SNA) is a methodology that provides complementary visual and statistical components for analyzing the traits and relationships of actors in a network. We conducted a study to develop a whole-network map of programs and their stakeholders to understand the diversity and reach of Extension programs in Pennsylvania. We concluded that the Penn State Extension network is widely distributed and has extensive reach in the community and that there exist a few program clusters (programs serving common stakeholders) and isolates (niche programs). Overall, SNA has much to offer in fostering understanding of the outreach of Extension and various outcomes of Extension programs.
