RESUMO

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.

RESUMO

The present article analyzes the relationship between characteristics of the journal Neotropical Ichthyology and its impact factor (IF) between 2006 and 2011 using bibliometric descriptive quantitative methods. To perform this analysis, two samples of journals included in Journal Citation Reports (JCR) were studied. One sample was composed of journals classified within the subject of zoology, and the other contained journals from different areas published in Brazil. The instrument used for data collection was a database created in Microsoft Excel 2007 and the Statistical Package for the Social Sciences (SPSS) version 18. The results show that despite its short history, Neotropical Ichthyology has exhibited a distinctive impact, as manifested in a significant progression in the IF of this journal in the field of zoology during the investigated period.


Este trabalho analisa as características do periódico Neotropical Ichthyology e de seu Fator de Impacto no período entre 2006 e 2011, utilizando métodos quantitativos descritivos do tipo bibliométrico. Duas amostras de periódicos indexados no JCR foram estudadas para a realização das análises: uma constituída pelos periódicos categorizados como sendo da área de Zoologia e a outra formada por títulos de diferentes áreas publicados no Brasil. O instrumento de coleta de dados foi um banco de dados criado no programa Excel versão 2007 e no SPSS versão 18. Os resultados encontrados nas análises mostram que o Neotropical Ichthyology é um periódico que, apesar de sua história recente de publicação vem apresentando uma evolução de impacto distintiva. Esse aspecto é demonstrado por mudanças significativas na classificação por IF na área de Zoologia no período analisado.
