Thank you!

Interesting, could you please send me your dissertation? That way, I can understand it better

Thanks for your interest! Integrating high-resolution employment data with our building classifications sounds like an interesting idea. It could indeed provide new insights, especially into the spatial relationships between employment centers and building types.

A big thank you to my co-authors, Sandro M. Reia, Shiyang Ruan, Kuldip S. Atwal, Hamdi Kavak, Taylor Anderson, and Dieter Pfoser.

What happens when a policy changes but the data is no longer available? We need to look at the mechanisms instead. In our newest pre-print (arxiv.org/abs/2312.09358), we study the effects of inadvertent social media content promotion on polarization & formation of echo chambers 1/4
