It’s been 10 years since I started teaching #QCA at the Social Sciences Summer School at @usi.ch in Lugano. So rewarding to see how PhD students and researchers apply the method in creative ways to topics from across the social sciences. Many thanks to this year’s group!

So Trump is making a 'deal' with Putin to reduce the impact of his own disastrous mistakes with Iran and the Strait of Hormuz, and thus further prolongs Russia's ability to wake war on Ukraine. Dumb, shortsighted, irresponsible. www.nytimes.com/2026/10/09/u...

🚨 The R Manual for QCA has been updated to version 4.2. It's a step-by-step guide to running #QCA in R, with a narrative PDF, an R script you can adapt for your own project, and sample data for the analysis and plots. patrickmello.com/qca/r-manual/ #QCA #rstats

And like everything else Trump touches, if he had just left it alone, it would be fine.

🚨 Last chance for QCA in Lugano (registration closes next Monday)!

The President of the United States is threatening to commit war crimes and wipe out a "whole civilization" — all because he started a disastrous war of his own making and had no plan and no strategy for how to end it. This is abhorrent, and the American people do not support this.

The work can by either inductive or deductive, start from PT or start from the cross-case; we want to get to know it all. 4/

More specifically, we are looking to show-case work that combines comparative case studies (CCS) or Qualitative Comparative Analysis (QCA) on the one hand, with Process Tracing (PT) on the other. 3/

For a book manuscript, Uncovering Causal Symptoms. Case Study Research, Process Tracing, and Qualitative Comparative Analysis, @patrickmello.bsky.social and I are looking for good (preferably published) work that combines cross-case with within-case analysis. 2/

We're hiring a Lecturer in Political Science @vuamsterdam.bsky.social (deadline Nov 24): 👉 werkenbij.vu.nl/vacatures/le...

Today's violation of Estonia's airspace by Russian military aircraft is an extremely dangerous provocation. This marks the third such violation of EU airspace in days and further escalates tensions in the region. The EU stands in full solidarity with Estonia (1/2)

Thanks for the wonderful turnout for this event: 86 people from 27 countries! 🌐🎉 The #QCA recording will be made available by @isanet.bsky.social via their channels.
