The next speaker in this AoIR 2019 session is the fabulous Jenny Stromer-Galley, who shifts our focus to 2014 and 2018 gubernatorial campaigns in the United States. She begins by noting the significant growth in negative advertising in U.S. elections, and this increase may also have led to a gradual decline in voter turnout as well as a general mistrust of political and democratic institutions.

Research into the uses of social media in political campaigning should aim to generate similar longitudinal datasets, to compare campaigning strategies over multiple cycles. This would also enable us to identify the rhythms of individual …

The next speaker in this AoIR 2019 session is the excellent Nik John, presenting a paper co-authored with Aysha Agbarya. Their focus is on Facebookunfriending practices between Jewish and Palestinian citizens of Israel during the Israel-Gaza conflict of 2014. From past studies, we already know that it is especially people with strong political views who unfriend, and such unfriending severs weak ties especially frequently; it also results from encountering unwanted group communication styles or online propaganda, and is used to manage one’s own personal public sphere in social networks.

But how do power relationships affect online tie-breaking practices? Are there …

I’ve spent all morning with AoIR business (and moved into my role as Past President), but this afternoon I’m finally attending another AoIR 2019 session, starting with the fabulous Luca Rossi. His focus is on the digital practices of migrants as they navigate the European border regime, especially in the context of the 2015/16 migration crisis.

The project has been using interviews and observations in migrant camps for part of its work, but another component of it has focussed on migrants’ uses of Facebook. t studied some 179 pages, containing 75,000 posts and 2.1 million comments, over a period …

The next session at IAMCR 2019 begins with my own paper, which presents an all-too-brief overview of the argument in my new book Are Filter Bubbles Real? (Spoiler alert: no.) The slides of my presentation are below, and a full paper is also available.

The next session at IAMCR 2019 starts with a paper by Matthias Degen, whose focus is on the challenges that journalists face when distributing news on Facebook in Germany. The platform is now reasonably well established in Germany, too, and this means that news outlets and journalists are also beginning to explore its use and perhaps normalising its use as part of their daily practices.

The project engaged in a quantitative analysis of the Facebook accounts of German political journalists from the federal press gallery (Bundespressekonferenz), and also conducted some short written interviews as well as a smaller number of …

The next speaker in this IAMCR 2019 session is Christian Baden, who shifts our focus to processes of polarisation. Some existing work on polarisation focusses on the themes and content along which groups are polarised, but in itself such differences may not be problematic; rather, the key issue here is whether such polarisation is increasing and results in incompatible perspectives.

Homophily and antagonism drive such processes. But homophily is extremely common and not necessarily a problem in itself; some homophily is natural, and it only becomes a problem in extreme situations. The question is therefore whether homophily increases over time …
