Brazilian Student and Professor Mobility

In this paper, we looked at the effect of mobility by students, post-doctorates and professors on science in Brazil. We analysed CAPES, CNPq, FAPESP and Incites data to examine the number of scholarships and their impact on posterior publishing. Decision trees, including the region of the country, length of stay by student and Professor, as well as institution abroad, were evaluated, along with logistic regressions. The number of incoming professionals to Brazil is still incipient. The number of undergrad students was not crucial in forming scientific ties, but the number of postgraduates (> 180 days) and professor stays (>90 days) was important. The highest impact factor of publications shows a greater probability of higher impact with more than six postgraduate students going to institutions in the global north region and professors staying for more than 90 days. Looking only at doctors and professors (Mobility after training), the country of most interest was the United States, followed by France and England, which are similar regarding professors. France had a greater emphasis on postdoctoral studies. Databases need to be improved to include factors such as gender and color/race as well as the origin of scholars from abroad.
