In our last newsletter we reported on how we applied social network analysis (SNA) to identify influencers in online public health communications networks.  This month we report on another application of SNA in our project with the Robert Wood Johnson Foundation to understand influence in state and local public health Action Networks.  Action Networks are clusters of organizations that have committed to work together to take action towards a shared vision.  For instance, Eat Smart Move More North Carolina is an “action network” with over 60 agencies, associations, and other partner organizations committed to increasing opportunities for healthy eating and physical activity, wherever people live, learn, earn, play, and pray in the State of North Carolina.  The success of Eat Smart Move More depends on hundreds of people, organizations, and communities doing their part to create the conditions for people to eat smarter and move more.
