This thesis investigates the role of network structure, brokerage, and framing in high-risk collective action. I use the protest movement that emerged in Russia following falsified national elections in 2011 and 2012 as an empirical case study. I draw on a unique dataset of nearly 30,000 online documents and the linking structure of over 3,500 Russian Web sites. I employ a range of computational social science methods, including Exponential Random Graph Modeling, an advanced statistical model for social networks, social network analysis, machine learning, and latent semantic analysis. I address three research questions in this thesis. The first asks if a protest network challenging a hybrid regime will have a polycentric or hierarchical structure, and if that structure changes over time. Polycentric networks are conducive to high-risk collective action and are robust to the targeted removal of key nodes, while hierarchical networks can more easily mobilize protesters and spread information. I find that the Russian protest network has a polycentric structure only at the beginning of the protests, and moves towards a less effective hierarchical structure as the movement loses popular support. The second research question seeks to understand if brokered text is actually novel, and if that text is more novel in polycentric networks than in hierarchical ones. Brokers are the individuals or nodes in a network that connect disparate groups through weak ties and close structural holes. Brokers are advantageous because they have access to and spread novel information. I find that the text among nodes in brokered relationships is indeed novel, but that information novelty decreases when networks have a hierarchical structure. The last research question asks if a protest movement in a high-risk political setting can be more successful than the government at spreading its preferred frames, and within such a movement, whether moderate or extremist framing is more prevalent. I find that the opposition is far more effective than the government in spreading its frames, even when the government organizes massive counter protests. Within the movement, moderates are more likely to have their framing adopted online than extremists, unless violence occurs at protests. The findings suggest that movements should build flatter, more diffuse networks by ensuring that brokers tie together diverse protest constituencies. The findings also provide evidence against those who claim that authoritarian governments are more effective in shaping online discourse than oppositional movements, and also suggest that movements should advance moderate framing in order to attract a wider base of support among the general population.

Ce travail de recherche s’appuie sur l’analyse ex post de la conception d’un dispositif de formation. Il est destiné à des conseillers agricoles, confrontés aux bouleversements de leur métier. Les exigences de l’agriculture performante économiquement et écologiquement, modifient l’exercice du métier de conseil agricole. Les pratiques de conseil sont perturbées par la mobilisation de l’agronomie pour inciter à réduire les intrants. Il s’agit de se doter d’un cadre théorique qui permette d’analyser les situations de conseil de conseillers, conjointement avec une méthode pour accompagner la réflexion, dans l’interaction conseillers/formateur. La didactique professionnelle et la sociologie de l’action sont convoquées pour appréhender la situation sociale de développement et la situation de formation comme moyen de la formation. Dans les dialectiques connaissances pour l’action, connaissances théoriques, le cadre de l’expérimentation a permis de saisir la faisabilité du conseil, l’accès aux possibles de l’activité de conseil, la coordination des actants pour construire l’action. Il en résulte, un dispositif didactique et coordonné qui garantit un cadre de travail construisant chemin faisant ce que les protagonistes cherchent à faire ensemble, une approche qui ouvre la voie à l’appréhension du social par la didactique professionnelle, l’émergence du métier. / This research work is based on the ex post analysis of the design of a training approach. It is targeted at agricultural advisors facing major changes in their job. The requirements induced by an economically and environmentally performing agriculture modify the job of advisor. The established practices of counselling are disrupted by the agronomy’s engagement to encourage the reduction of inputs. The objective is to design a theoretical frame, allowing to analyze the advisors’ counselling situations, supported by a methodology to back up the reflection and with interactions advisors / trainers. Professional didactic and sociology of action are summoned to appreciate the social situation of development and the training situation as means of training. In the relationships between knowledge for action, theoretical knowledge, the experimentation framework allowed to seize the feasibility of counselling, the access to the potential of the counselling activity and the coordination of the stakeholders to build the action. This leads to a coordinated learning approach with a framework creating along the way what the protagonists are seeking to do together; an approach opening the path to understanding the social component by professional learning; the job emergence.
