ABSTRACT. In this article, we have built a co-authorship network among researchers with CNPQ grant in research productivity (PQ) in the area of Industrial Engineering and analyze which Social Network Analysis metrics impact their productivity level. Unlike other studies that mostly analyze unweighted networks, ours explored more broadly the network since the metrics were calculated in three ways: unweighted, including the edges weights and including the edges and nodes' attributes. Thus, the generated results are more precise and detailed since more information is obtained. We consider the h-index of the researchers as the nodes' attributes and measured the impact using Kendall correlation. We show that geographical distance is still a barrier to collaboration among PQs in this area and that collaboration with researchers with different levels of grant has the greatest impact in the level of the grant a researcher has.
Neste artigo, construímos uma rede de coautoria entre os bolsistas de produtividade do CNPq da área de engenharia de produção e analisamos quais métricas de ARS impactam nos níveis de produtividade deles. Nossos resultados indicam que o nível de produtividade apresenta correlação de Spearman positiva significativa com cinco de sete métricas analisadas. Concluímos que os pesquisadores que assumem um papel de intermediador", que possuem um maior número de ligações ou têm maior facilidade de estabelecer parcerias de publicações, tendem a ter maior nível de produtividade. Além disso, constatou se também que colaborar com frequência com os mesmos pesquisadores não impacta no nível de produtividade."
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
