From: The emergence of heterogeneous scaling in research institutions
a Collaborations between institutions. Each node represents a research institution, and institutions with more researchers are represented by larger nodes. Each link represents collaborations between researchers at different institutions and more collaborations are represented by thicker lines. Darker nodes represent faster-growing institutions (defined as the number of new researchers added between 2012 and 2017), and darker links represent faster-growing collaborations (defined as the number of new inter-institution collaborations between 2012 and 2017). Links with fewer than 10 collaborations are removed, as are isolated nodes. A few major universities are labeled: Peking University, Oxford University, Harvard University, Massachusetts Institute of Technology (MIT), and the University of Southern California (USC). b The largest connected component of collaborations within Harvard University. Each node represents a researcher. Dashed lines represent new collaborations added between 2012 and 2017, while open circles represent new researchers added between 2012 and 2017. The highest degree node is Ichiro Kawachi, a highly cited sociologist.
