Abstract
In recent decades, we have observed an intensification of science, technology and innovation activities in Brazil. The increase in production of scientific papers indexed in international databases, however, has not been accompanied by an equivalent increase in the impact of publications. This paper presents a methodology for analyzing production and the impact of certain research areas in Brazil related to two aspects: the origin of the journals (national or foreign) and international collaboration. These two variables were selected for being of particular importance in understanding the context of scientific production and communication in countries with emerging economies. The sample consisted of papers written by Brazilian researchers in 19 subfields of knowledge published from 2002 to 2011, totaling 85,082 papers. To calculate the impact, we adopted a normalized indicator called the relative subfield citedness (Rw) using a window of 5 years to obtain measurements evaluated in 2 different years: 2007 and 2012. The data on papers and citations were collected from the Web of Science database. From the results, we note that most of the subfields have presented, from one quinquennium to another, improved performance in the world production rankings. Regarding publication in national and foreign journals, we observed a trend in the distribution maintenance of production of the subfields based on the origin of the journal. Specifically, for impact, we identified a lower Rw pattern for Brazilian papers when they were published in national journals in all subfields. When Brazilian products are published in foreign journals, we observed a higher impact for those papers, even surpassing the average global impact in some subfields. For international collaboration, we analyzed the percentage of participation of foreign researchers and the connection between collaboration and the impact of papers, especially emphasizing the distinction of hyperauthorship papers in terms of production and impact.
Highlights
In recent decades, we have observed in countries with emerging economies an expansion of production activities at different levels, including the sectors of science, technology and innovation (ST & I) [1]
The subfields included in this study were those with at least 1 Brazilian journal indexed in the 2002 edition of the Journal Citation Report (JCR)
Further analyzes aim the characterization of the Brazilian production when published in its own journals, and when published in journals edited by other countries
Summary
We have observed in countries with emerging economies an expansion of production activities at different levels, including the sectors of science, technology and innovation (ST & I) [1]. In 2002, 6,894 PhD degrees were awarded [3] and 16,240 papers were published in journals that were indexed in international databases[4]. Ten years later, these numbers were 13,912 and 44,001, respectively. Among 239 countries, Brazil ranked 17th [4,5] in the world ranking of scientific paper production in 2002, ascending to 13th [5], or 14th [4] in 2011, depending on the database used. According to the Ranking of Countries produced by SCImago [5], Brazil is among the 30 most productive countries in science, at the 24th position in the ranking of citations per paper
