“…Accordingly, productivity analyses using a bibliometric approach allow areas of greater or lesser proximity to be identified, and, thus, the interdisciplinarity of knowledge (Heberger et al, 2010); furthermore, similar analyses have been conducted on cooperation between authors or types of research (Garcia, López-López, Acevedo-Triana, & Nogueira Pereira, 2017;Robayo-Castro, Rico, Hurtado-Parrado, & Ortega, 2016). This cooperation could be understood as joint efforts towards the common goal of scientific productivity (Garcia, López-López, Acevedo-Triana, & Bucher-Maluschke, 2016). One form of cooperation is publication co-authorship, which has been used to assess collaboration between researchers and contrasts with other forms of cooperation, such as joint research projects, development of regional associations, creation of academic events, and scholar exchanges (Garcia, Acevedo-Triana, & López-López, 2014).…”
