Over on the arXiv there’s a paper–complete with interactive visualization–that determines those cities that produce more highly-cited research than would be expected. The aptly, albeit lengthily, named Which cities produce worldwide more excellent papers than can be expected? A new mapping approach–using Google Maps–based on statistical significance testing uses a fairly straightforward procedure of finding these cities. The authors, Lutz Bornmann and Loet Leydesdorff, control for size to see which cities have higher impact research than would be expected based on their total output in papers. And doing this, they find that many cities in the United States and Europe are better at producing good research than expected by the null hypothesis, and a number of cities in the former Soviet Union that perform less well than expected:
