Part of the Working Papers in Sociology series from Oxford University, this work addresses the dynamics of protest diffusion by taking an in-depth and rigorous look at the 1960 sit-in movement that took place in different locations around the South. Within the papers 31 pages, Professor Kenneth Andrews of Harvard and Professor Michael Biggs of the University of Oxford offer a brief exposition of previous research into the spontaneity and organization in the dynamics of social movements, along with presenting their own approach to this oft-contested area of scholarship. Using cross-sectional regressional models and event history analysis, the authors are able to show support for the significance of formal movement organization in the initial period of protest, and the diffusion effect, where the existence of previous protests would increase the likelihood of further protest. While the authors note that their results are not that surprising, their efforts here are some of the first to systematically utilize a quantitative approach to examining this powerful social movement.
