In this paper, published in the American Journal of Community Psychology, the authors argue that attempts to change social settings have been hindered by lack of theoretical advances in understanding key aspects of social settings and how they work in a dynamic system. They present a systems framework for understanding youth social settings, focusing on three aspects of these settings that represent intervention targets: social processes (i.e., patterns of transactions between two or more people or groups of people), resources (i.e., human, economic, physical, temporal resources), and organization of resources (i.e., how resources are arranged and allocated). They postulate that these setting aspects are in dynamic transaction with each other, resulting in setting outcomes.
