Trends in scientific mobility and collaboration

This is a good article by Elizabeth Redden in Inside Higher Ed, Bibliometrics and Academic Mobility.

Researchers at Elsevier, the academic journal publisher, have used bibliographic data to identify trends in scientific mobility and collaboration across 17 countries. Tracking unique author IDs, they documented authors’ movements from one country to another and identified rates of co-authorship between scientists from different countries. They found that migration and co-authorship are distinct trends, driven by different factors. For example, shared language and geographic proximity drive rates of migration more strongly than they influence rates of co-authorship between countries. The authors also note that political tensions have less of an effect on migration than they do on co-authorship. Relative to rates of co-authorship, the researchers found high rates of migration from Taiwan to China, Iran to the United States, and between India and Pakistan.
