A major goal of this dissertation is to model large urban areas, even entire cities, which is an enormous challenge due to the sheer scale of the problem. Even a partial data capture of the town of Chapel Hill requires millions of frames of street-level video. The methods presented in ...
segregation because only 2.4% of exposures (95% CI = 2.4–2.4%) occur when both individuals are within their home tract. Finally, we observe that not only is overall exposure segregation elevated in large cities, but also each of its components is elevated in large cities (Supplementary ...

In Chinese large and medium-sized cities, the contribution of mobile sources to air pollution is always higher than that of stationary sources; this is also applicable to Lanzhou, where the NO2/SO2 ratio is >1.7 over the long term, and mostly >3, the averages for 2016–2022 are 3.23 (...
In this article, we analyze the relationship between mobility and the extractive economy of large copper mining in the Antofagasta region, located in the north of Chile. We will argue that extractivism generates various types of mobilities, which result
As Democrats gain momentum, Republicans are digging in, echoing Trump’s harsh criticism of the nationwide protests over police violence, particularly against Black people. He sounds dire warnings about the demonstrations happening in some cities. It’s an opening for the GOP, an attempt to win ...
