This is the third of a four-part study that explored the function of social networks in school community relationships in Pontiac, Michigan. The research consisted of utilizing any available data on Pontiac to supplement the researchers' in-depth analysis of community networks. This volume begins by discussing modifications in the original research design and reviewing the issues of latency and trust in network analysis. Chapter two describes the history, activities, location in the interorganizational network, and significance in school community relations of the Pontiac chapter of an influential national black sorority. Chapter three outlines efforts to map the helping interorganizational network in the city; based on this analysis, it is concluded that the school is defined by persons both inside and outside as a specialized organization, but not a helping organization. Chapter four explores the history, activities, and network structure of Pontiac's Coalition for Community Change, while chapter five provides similar information for the Parents' Advisory Group. The final chapters of the book focus on the school system, its relationship with community organizations, and the importance of community politics and racial relations in such issues as desegregation. In conclusion, the potential role of social networks in educational innovation is considered. (GC)
