Quel point commun existe-t-il entre les footballeurs Jean-Marc Bosman, Nicolas Anelka (à l'époque où, mineur, il quitte le club du PSG pour celui d'Arsenal), et Philippe Mexès ?Ces trois footballeurs ont fait l'objet d'affaires révélant des initiatives individuelles dont l'arrière plan en vient à discuter l'application de la liberté de circulation des footballeurs. Tandis qu'ils revendiquent une cause personnelle pour davantage de justice les concernant, les protagonistes qui se mobilisent transforment la dispute. On assiste à l'ouverture de débats qui, dès lors, dépassent la cause individuelle du footballeur. Il en résulte que le programme met en exergue ce que font les acteurs lorsqu’ils questionnent ce qui semble aller de soi. La thèse examine également les protagonistes dans le cours de l’action face aux transformations successives des débats. Enfin, elle s'intéresse à la façon dont un simple cas en vient à reconfigurer le milieu du football et par là, à impulser et à engager des transformations sociales plus larges. / What do the football players Jean-Marc Bosman, Nicolas Anelka (as a young player, when he leaves the football club PSG for Arsenal), and Philippe Mexès have in common?These three football players have been at the center of sports affair revealing individual initiatives where the background concerns the application of the freedom of movement for football players. Although in each case, the football players call for an individual cause, the cause is transformed during the polemics by the protagonists. We notice that the debate opens up for other issues which overrun the football player’s individual cause. This research focuses on what the actors do when they are questioning the matter of course. This thesis also examines the protagonists in their action when faced to the transformations of the debate. Finally, the thesis explores how a simple case reconfigures the world of football and hereby animates and initiates social transformations on a larger scale.

Tanto porque eles permitem uma formalização mais precisa dos fenômenos sociais, quanto porque recriam comportamentos sociais com maior realismo. Um dos fenômenos mais característicos da sociedade é a formação de opinião de indivíduos dado uma determinada situação de escolha. Este trabalho propõe a formalização do fenômeno social da formação de opinião entre um grupo de atores onde só é possível assumir uma ou outra opinião (cenário dicotômico). Para isso, foi proposto uma abordagem computacional baseada em agentes para a simulação desse cenário com o objetivo de melhor entender esse processo. / Computer modeling has been gaining ground in the social sciences. Both because they allow a more accurate formalization of social phenomena, and because it recreates social behaviors with greater realism. One of the most characteristic phenomena of a society is the opinion formation of individuals as a given situation of choice. This paper proposes the formalization of social phenomenon of opinion formation between a group of actors where it can only take one or other opinion (dichotomous scenario). For this, we propose an agent-based computational approach to simulate this scenario in order to provide a better understanding of this process.
