Xinyi Zhao, Samin Aref, Emilio Zagheni +1
Germany has become a major country of immigration, as well as a research powerhouse in Europe. As Germany spends a higher fraction of its GDP on research and development than most…
Multilevel Structural Evaluation of Signed Directed Social Networks based on Balance Theory
Samin Aref, Ly Dinh, Rezvaneh Rezapour +1
Balance theory explains the forces behind the structure of social systems, which are commonly modeled as static undirected signed networks. We expand this modeling approach to inco…
Scholarly migration within Mexico: Analyzing internal migration among researchers using Scopus longitudinal bibliometric data
