The Brazilian Anti-Dam Movement
研究巴西反坝运动如何通过挑战和重塑科学知识来推动目标，运用哈贝马斯的传播行动理论分析活动家与研究者的合作如何产生新的科学概念并传递给公众。
The environmental movement has often contested and reshaped scientific knowledge to achieve its goals. However, theorists have yet to account for this social movement tactic. This research uses a case study of the anti-dam movement in Brazil, with particular reference to three instances of anti-dam activism across the country, to delineate how scientization of the state motivates environmental movements to contest science. It uses Jurgen Habermas's theory of communicative action to explicate how instrumental and communicative claims are deliberated on in collaborations between activists and researchers, resulting in new scientific conceptualizations. These results are then translated to the public through innovative movement frames. This research helps situate communicative action as a social movement strategy important in a global knowledge society.
