The third cohort of our MSc AI & Government and MSc AI & Sustainable Development starts this week at Birmingham. Seeing students grow is the best part of the job. Here is to a new academic year. Ad astra per aspera! #AI #sciencerocks

On my way back from #polmeth2026. It was truly a blast. Thankful for the community. A shoutout to all organisers. Right now, I am really tired and desperate for the summer break, but incredibly motivated. Looking forward to the months ahead. #sciencerocks

When the far right enters parliament, established parties go high on average. But right after a far-right speech, they answer madly in anger: in words, voice, and body. Joint work with @ankuepfer.bsky.social and @pluggedchris.bsky.social presented at #PolMeth2026 at Michigan State.

I feel these takes are often narrow regarding what includes social science. I am sympathetic to the idea of qualitative research and fieldwork becoming rel more weighty as AI improves. ATM, these changes seem most drastic for quant analysis. What really changed for qualitative inquiry, yet?(1/2)

👏Applause offers a revealing lens on party competition! In a recent article @wepsocial.bsky.social (w/@jocmuel.bsky.social+@pluggedchris.bsky.social), we study how applause reflects party and coalition unity, ideological agreement, political exclusion, issue ownership, and the electoral cycle! (1/6)
Cover page of the article:
"The sound of party competition: how applausereflects unity, disagreement, and the electoralcycle in parliamentsAndreas Küpfera , Jochen Müllerb and Christian Steckeraatechnical university of Darmstadt, Darmstadt, Germany; buniversität Greifswald, Greifswald,GermanyABSTRACTThis article studies how applause reflects the dynamics of party competitionduring parliamentary debates. While legislative scholars often emphasise theselection of speakers and content of debates, spontaneous reactions from fel-low MPs remain understudied. Analysing 750,000 instances of applause in thedebates of the German Bundestag (1976–2020), it was found that applausepatterns, although largely spontaneous and immediate by nature, systemati-cally reflect incentives from party competition such as signalling party andcoalition unity, ideological (dis)agreement, and ostracising specific parties.Applause also indicates issue emphasis, especially near elections. The findingssuggest that applause can serve as a nuanced and abundant indicator in thestudy of party competition, complementing more static measures derived frommanifestos and expert judgements. By analysing applause patterns over fourdecades, this study opens new avenues to explore nonverbal reactions asmarkers of party competition in other parliaments."
