The Cologne “Grüngürtel” (Green Belts) emerged from former fortress areas. Mayor Konrad Adenauer recognized the importance of a natural air filter for the people in the city. The Inner Green Belt and the Outer Green Belt were built between 1922 and 1924.

dplyr but make it bussin fr fr no cap
`genzplyr` is an alternative syntax for `dplyr` that replaces boring old function names with GenZ slang. Your data wrangling is about to hit different.

A new paper analyzes the “production-consumption gap” on social media, where a small subset of users produce most of the content, and considers its implications for the study of phenomena such as political polarization, and for the design of policy interventions. Prithvi Iyer considers the results:

Prithvi Iyer considers new research on how online content reveals the tip of the iceberg, leading to incorrect inferences about online public opinion.

Why do rustbelts vote radical right? Studying the German Ruhr area, @nilsblossey.bsky.social, @lstoetze.bsky.social and I show: it’s not just about deindustrialization, but also about the original industrialization. Where coal is buried deeper and mining started later, the AfD is stronger today 1/12

🗳️ New study (w @jessicakuhlm.bsky.social) on AfD success in integration council elections in North Rhine-Westphalia, Germany: AfD achieved significant results in councils elected exclusively by voters with migration backgrounds. It's not about economics—it's about political competition. (1/3)

“In my work with the (Nuremberg Trial) defendants, I was searching for the nature of evil, and I now think I have come close to defining it. A lack of empathy... a genuine incapacity to feel with their fellow men. Evil, I think, is the absence of empathy.”
