Today is the last day of the summer term at @uni-konstanz.de. The last weeks have been extremely exhausting, due to the fact that only very few rooms on campus have A/C. This was by far the worst summer in the history of our institution (see below). You wonder why teaching ends so late? So do I.
Gratulation zum Semesterende, @uni-konstanz.de! Die letzten Wochen waren echt zäh, oder? Dies war (mit deutlichem Abstand) das Sommersemester mit den meisten Hitzetagen in der Geschichte unserer Uni. Bitte lasst uns über die Semesterdaten sprechen. www.jmwiarda.de/blog/2026/06...
Heute bin ich in @jmwiarda.bsky.social's Blog zu Gast, mit einem Beitrag zur Hitze im Hörsaal und wie sie sich ganz einfach vermeiden liesse: www.jmwiarda.de/blog/2026/06...
Hitzekollaps im Hörsaalwww.jmwiarda.deWould be great to do something similar at the @jpeaceresearch.bsky.social.
DanbischofI like this @thejop.bsky.social : "We are now implementing a system in which the editorial team has the right to not consider submissions from authors who have failed to review for the journal three or more times, when invited to do so by the editorial team."
Inequality matters for ethnic conflict. But do group elites actually frame a situation as unjust? In a recent article (doi.org/10.1177/00323217251401758), @frederikgremler.bsky.social, Lea Haiges, Christina Zuber and I analyse “grievance frames” in social media posts of ethnic organisations.

Thanks to the great help by @rstrauch.bsky.social, Gabriele Spilker and the Cluster of Excellence "The Politics of Inequality" @excinequality.bsky.social, version 5.0 of the "Mass Mobilization in Autocracies Database" (coverage until 2022) is now available at mmadatabase.org!
Mass Mobilization in Autocracies Databasemmadatabase.orgThis is an excellent special issue! Highly recommended.
Andrea RuggeriThanks to @jpeaceresearch.bsky.social for giving us the possibility to guest edit a special issue on "Political violence in democracies". Ursula Daxecker, @neerajprsd.bsky.social and I wrote an open access introduction: journals.sagepub.com/doi/full/10.... Thanks to all authors of 14 articles!
Thanks for the endorsement, @kailmarkvart.bsky.social! This work was only possible because there's a large coding project with full transparency in its procedures and data, and with unrestricted access. Kudos (again) to the @vdeminstitute.bsky.social for providing this huge public good.
Kyle MarquardtNow with page numbers! Really happy to already see excellent work applying these findings to similar projects regarding LLMs. For example: doi.org/10.1017/S104...
This article should have been published alongside the one it responds to. The original article finds that the authors' own (commercial) data outperforms the free UCDP data. Conflict of interest? Nah. But at least we know now that this conclusion is based on "a series of unfounded claims." 👇
Magnus ÖbergMy new article with Mert Can Yilmaz out in Research & Politics! An investigation into what does drive differences between UCDP and ACLED data and a response to a series of unfounded claims made by Clionadh Raleigh et al in a 2023 article. (1/4) Read it here doi.org/10.1177/2053...
... and here's a short press release about the article: www.uni-konstanz.de/en/universit...
Beyond health: The political effects of infectious disease outbreakswww.uni-konstanz.deNils WeidmannVery happy that the joint paper with Ore Koren on infectious diseases and trust in politics has now been published: www.pnas.org/doi/10.1073/... A nice result of his fellowship at @uni-konstanz.de, funded by the @humboldt-foundation.de!
