Marilyn Aronoff specializes in community theory and research, processes of collective action, and qualitative field methods. Central to her interests are the variations observed in local community responses to economic and environmental crises. She is currently working on a comparative study of the range of local reactions to toxic waste contamination in Michigan Superfund site communities. Variations in the level and type of local mobilization, revealed in the aftermath of these disasters, are examined in relation to differences in the characteristics of the local communities that face them and the particular patterns of external intervention experienced in their aftermath. The project hopes to retain the depth of understanding achieved in qualitative community studies while overcoming the limitation of dependence on only a very small number of cases as we seek to understand the range of variation in human response.
