A selfie of me in front of an old white church with a Pride flag in the right window in the late afternoon. I'm a bald, middle-aged, white man with a red beard flecked with white. I'm wearing glasses with a metal top rim, a blue wrap around earbud in my left ear, and a red t-shirt.
It was positively toasty out today, and while basking in the unseasonable weather I listened to talks for my #AcademicRunPlaylist! (1/8)
Thanks @sewenz.bsky.social !! I will definitively have a closer look at your work.
Thanks, Klaus! 🙏🏻😃

Congrats 🎉
Example for the two staged unsupervised machine learning algorithm using point data as input. Backlayer maps depict Hamburg. The map shows neighborhoods in different sizes and forms, sometimes following administrative borders (black lines) sometimes not. Three differently colored neighborhood types are displayed, each representing a different social group of residents.
xample for the two staged unsupervised machine learning algorithm using 500x500m grid cells as input. Backlayer maps depict Hamburg. The map shows large neighborhoods in different sizes and forms, sometimes following administrative borders (black lines) sometimes not. Three differently colored neighborhood types are displayed, each representing a different social group of residents.
Looking for a measure of #neighborhoods, micro or macro #segregation?
I've got something for you!
My newly published paper in Sociological Methods & Research presents a machine-learning-based algorithm to delineate neighborhoods with grid-cell or point data:

Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:
🙏 Thanks to #ECSR2025 for a great conference! Inspiring to see so much interest in our meta-analysis on parenthood discrimination in hiring.

#VET students drop out more often when the local economy is good, but what happens with dropouts' wages if such a good local economy turns bad in the following years?
If you want to know more, come to my talk in the "Returns to education" session (today 3:30pm, S12) at #ECSR2025!

Protest and the rise of left-nationalist challengers: evidence from Germany
📔 Social Movement Studies

In 2022, Germany faced a cost-of-living crisis.
Many expected a “Hot Autumn” of mass protest—but it never happened. Why?
👩🎓 Work in Sweden: The Institute for Analytical Sociology offers 2 fully funded PhD positions! liu.se/en/work-at-l...
What do local govts in Switzerland do when they’re unhappy with federal policy but lack formal channels to voice their concerns?
They threaten not to clear snow from the roads so federal officials can no longer reach the asylum centers they oppose. Protest as another form of intergovt lobbying!
"Why women leave academia: A longitudinal study of the leaky pipeline in German sociology" new preprint osf.io/preprints/os...
3/3
⚖️ Yes—underperformance increases the risk of leaving academia.
But this applies to both men and women, challenging the idea that academic attrition is solely driven by performance-based self-selection.
2/3
👩👧 Among women: mothers tend to be more likely to exit academia than childless women.
Also, women face a much higher risk of leaving academia at the pre-doc stage, where family formation and academic uncertainty often intersect.
1/3
📉 Women in German sociology face a 35% higher risk of leaving academia compared to men.
Importantly, this gap cannot be explained by gender differences in parenthood, career stage, productivity, or academic rewards.
