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

11 Presentation The Editors This book is one of the results of the III International Seminar on Research onMediatization and Social Processes held in 2019. The III International Seminar on Research onMediatiza- tion and Social Processes had a programdeveloped on two levels: Debate Tables, with invited researchers (five discussion tables, with the participation of researchers from France (3), Argentina (2), Germany (1), and Brazil (5). The schedule of the III Seminar and its structure can be seen at https://www.midiaticom.org/ seminario-midiatizacao/grade-de-programacao-2019/. In total, there were 15 hours of debates at the five Dis - cussion Tables. Methodologically, the Seminar takes place in the articulation of Debate Tables with international guests and Working Groups with the presence of researchers, doctors, doc- toral students, masters, and masters’ degree students. We point out that, even in the scope of training process- es, master’s and doctoral students, masters and doctors, post- doctors and post-doctoral graduates, and members of the orga- nizing Research Group take part as reviewers, in a blind evalua- tion process, of the expanded abstracts submitted by graduates with a lower title - under the coordination of the research pro- fessors from the Mediatization and Social Processes Group. They evaluated (in a group of more than three dozen reviewers) each of the works submitted by colleagues with a lower instructional level, with classificatory notes, which resulted in the approved works. They were then grouped by the Organizing Committee, successively, until they reached the event’s working groups. The average number of submissions to the Working Groups, in the three events held, is 200 expanded abstracts, dis- tributed among professors, researchers (around 20%), doctors and doctoral students (around 30%), masters professors, and
