What is the point of activists blocking roads or interrupting sports events? Clara Vandeweerdt shows that these kinds of protests are excellent at drawing attention to their cause. On the other hand, they slightly decrease support for the protesters' policy demands. Read the paper: rdcu.be/eJJrR

Greece has unusually many news outlets, but that does not mean its media landscape is diverse. Most websites cover the same broad topics--even more so when they take over news agency content, and when websites have the same owner. Read more in Yani Kartalis' paper: eprints.lse.ac.uk/129624/1/Gre...

I'm glad to be a coauthor of the excellent Marilena Hohmann for this paper proposing a way to measure affective polarization on social media: https://doi.org/10.1371/journal.pone.0328210
Estimating affective polarization on a social network
Concerns about polarization and hate speech on social media are widespread. Affective polarization, i.e., hostility among partisans, is crucial in this regard as it links political disagreements to hostile language online. However, only a few methods are available to measure how affectively polarized an online debate is, and the existing approaches do not investigate jointly two defining features of affective polarization: hostility and social distance. To address this methodological gap, we propose a network-based measure of affective polarization that combines both aspects – which allows them to be studied independently. We show that our measure accurately captures the relation between the level of disagreement and the hostility expressed towards others (affective component) and whom individuals choose to interact with or avoid (social distance component). Applying our measure to a large-scale Twitter data set on COVID-19, we find that affective polarization was low in February 2020 and increased to high levels as more users joined the Twitter discussion in the following months.

While human behavior and the data describing it evolve over time, fairness is often evaluated at a single snapshot. Yet, as we show in our newly published paper, fairness is dynamic. We studied how fairness evolves in dropout prediction across enrollment and found that it shifts over time.
