Studies of political polarization in social media demonstrate mixed evidence for whether discussions necessarily evolve into left and right ideological echo chambers. Recent research shows that, for political and issue-based discussions, patterns of user clusterization may differ significantly, but that cross-cultural evidence of the polarization of users on certain issues is close to non-existent. Furthermore, most of the studies developed network proxies to detect users’ grouping, rarely taking into account the content of the Tweets themselves. Our contribution to this scholarly discussion is founded upon the detection of polarization based on attitudes towards political actors expressed by users in Germany, the USA and Russia within discussions on inter-ethnic conflicts. For this exploratory study, we develop a mixed-method approach to detecting user grouping that includes: crawling for data collection; expert coding of Tweets; user clusterization based on user attitudes; construction of word frequency vocabularies; and graph visualization. Our results show that, in all the three cases, the groups detected are far from being conventionally left or right, but rather that their views combine anti-institutionalism, nationalism, and pro- and anti-minority views in varying degrees. In addition to this, more than two threads of political debate may co-exist in the same discussion. Thus, we show that the debate that sees Twitter as either a platform of ‘echo chambering’ or ‘opinion crossroads’ may be misleading. In our opinion, the role of local political context in shaping (and explaining) user clusterization should not be under-estimated.

The crisis in Ukraine was one of the dominant topics in international news coverage of 2014 and the following years. Representing a conflict along the lines of an East-Western confrontation unprecedented since the end of the Cold War, the news reporting in different European countries with different historical backgrounds is an essential research topic. This article presents findings of a content analysis examining coverage of the conflict in the first half of 2014 in newspapers from a diverse set of 13 countries: Albania, Czech Republic, Germany, Latvia, the Netherlands, Poland, Portugal, Romania, Serbia, Switzerland and the United Kingdom, as well as Ukraine and Russia. Drawing on prior literature on news values, key events, and news cycles in foreign coverage, this study maps the evolution of the conflict in the course of four key events and identifies specific characteristics of the coverage in different newspapers. The results show that attention for the conflict varies considerably across the countries, which might be traced back to different degrees of geographical and cultural proximity, domestication, and economic exchange, as well as lack of editorial resources especially in Eastern Europe. Russia dominated the news agenda in all newspapers under study with a constant stream of conflict news. Contradicting prior literature, media sought to contextualise the events, and meta-coverage of the media’s role in the crisis emerged as a relevant topic in many countries with a developed media system.
