Mediatization, polarization, and intolerance (between environments, media, and circulation)

117 Collectives, circulation of social discourses, and citizen mobilization: the case of #RosarioSangra 1 Natalia Raimondo Anselmino 2 Abstract : This paper is the product of a group and interdisci- plinary research aimed at analyzing the ways in which social discourses on the public-political that are visible when they are put into circulation through social media platforms such as Facebook or Twitter acquire, outside of them, visibility located in the co-presence of the more traditional public space or media visibility. In pursuit of this objective, some reflections are pre - sented following the study of a unique case of an instrumental nature: the citizen mobilizations for “security and justice” that happened in the city of Rosario (Argentina), under the slogan #RosarioSangra, during the second half of 2016. The ideas thus shared seek to understand the articulation between different visibility regimes of public-political discourses as well as the intersections between socio-individual and collective actors in hypermediatizated societies. Keywords : Citizen mobilization. Social discourses. Circulation. Collectives. Mediatization. 1 This article is a rework of the exhibition presented on the occasion of the III In- ternational Seminar on Research on Mediatization and Social Processes (UNISI- NOS, 2019) and has originally been published in Revista Sociedad, n. 39 (No- vember 2019 to April 2020), from the Universidad de Buenos Aires, Argentina. 2 Professor at Universidad Nacional de Rosario (UNR) and researcher at CONICET.
