A CO-AUTHORSHIP NETWORK ANALYSIS OF RESEARCH FROM GRADUATE PROGRAMS OF THE INTERDISCIPLINARY AREA IN BRAZIL

Resumo

Scientific collaboration has an increasing acknowledgment as one of the keys to research
quality, which impacts the academic performance of graduate programs (GP). This investigation
assesses the researchers' collaboration in terms of the co-authorship network formed by scientific papers
published by permanent professors in Brazilian GPs from the Interdisciplinary area in 2017. In general,
the co-authorship network is formed by permanent professors as the vertices, and the joint publication
of a paper identifies the edges. We obtained data from the Sucupira and Lattes platform of a sample set
of 1040 permanent professors, in 56 graduate programs, in 48 universities for the 2017 year. For each
GP, a collaborative network was created based on published articles, and topological parameters, like
cluster coefficient, density, diameter, degree, and shortest path were calculated. Other variables have
been taken into consideration to help the analysis, such as the GPs number of permanent professors, the
GPs evaluation grade applied by CAPES in the 2013-2016 period analysis, the university management
type (public or private), and the region from Brazil where it is located. Therefore, the objective is to
verify the variables which may indicate the GP quality, and although the properties of the network are
not statistically related to the GP quality, they help to analyze some characteristics of GPs according to
the management type of the institution.
