Research on Collective Action, Protests, and Social Movements

My recent work has focused on racial disparities in imprisonment, which you can see in the “racial disparities” section of this web site.

The PowerPoint slides for my talk “The Ethnic Dimensions: Bringing ethnic divisions & conflict to the center of social movement theory” given at Notre Dame on May 5, 2012 on the occasion of my receiving the John D. McCarthy Award for lifetime achivement in social movements. Here is a PDF of the slides. This is a text write up of the talk.


My paper, “Repression and Crime Control: Why Social Movements Scholars Should Pay Attention to Mass Incarceration as a Form of Repression,” a revision of the paper I presented at the Social Movements Workshop August 9, 2007, explains the link between these two lines of work.


My paper “Talking About Racial Disparities in Imprisonment,” presented at the meeting of the International Sociological Association in Durban, South Africa on July 24, 2006, is in revision for publication in Handbook of Public Sociology, edited by Vincent Jeffries. It discusses my experiences in doing public sociology.


My recent work on research on protests and social movements falls into two somewhat-overlapping projects :

  1. empirical studies of the interrelations of protests, news coverage, and political processes and
  2. development of formal models of the coevolution of social movements and cycles of protest.

Note: work on these projects summarized on this page was supported in part by NSFgrants #SBR9819884, SBR 96-01409 and SBR 95-11748.

Diffusion and Coevolution Models of Protest

This project involves reframing social movements as coevolving systems of protest, politics, and news coverage. Papers and models are in process.


Critical Mass Theory

My older work on selective incentives and my work with Gerald Marwell on the Critical Mass shows how the problem of collective action cannot be reduced to a problem of individual decision-making but requires a theory of group structure and group coordination and must take account of group heterogeneity. This work is summarized in the collection of abstracts.


The Content and Timing of Media Coverage of Message Events: Cycles and Comparisons

For this project, we have collected data on public events (including protests) from multiple police agencies in Madison, Wisconsin, and searched local newspaper archives to determine which received news coverage. Current work focuses on determining whether protest affects media coverage of issues.
