Cuban scientific production in Medicine and Public Health: Scopus 2003-2011

El objetivo de este trabajo fue analizar la evolución del volumen y la visibilidad de la producción científica cubana en Salud Pública y en Medicina para determinar si siguen los mismos patrones de comunicación, y recomendar buenas prácticas de publicación. Se aplicaron indicadores bibliométricos de volumen, visibilidad y colaboración extraídos del portal SCImago Institutions Rankings a partir de datos de Scopus, para el área temática Medicine y la categoría Public Health, Environmental and Occupational Health, período 2003-2011. Cuba tiene una posición relativamente alta en los rankings de volumen de producción científica tanto en Medicina como en Salud Pública en los contextos internacionales y regionales, mientras que en impacto está entre los últimos países. La tendencia de la producción es al crecimiento, aunque en Salud Pública es más acelerado. El liderazgo es alto, pero la colaboración internacional está por debajo de lo esperado. La publicación en revistas de alto impacto (primer cuartil) y los artículos en el 10% más citado (excelencia) son escasos. Se concluye que el volumen y el impacto de la publicación no están acorde al potencial científico de salud cubana. Se recomienda incrementar la colaboración científica, la publicación de artículos en revistas de alto impacto, la preparación de los recursos humanos y seguir las recomendaciones internacionales sobre las buenas prácticas de edición y publicación científica.The aim of this study was to analyze the evolution of the quantity and visibility of Cuban scientific production in Public Health and Medicine to determine if they follow the same patterns of scientific communication and the recommended best practices for publication. Bibliometric indicators of quantity, visibility and cooperation were extracted from the SCImago Institutions Rankings website, which is based on Scopus data, in the field of Medicine and category of Public Health, Environmental and Occupational Health from 2003 to 2011.Cubahas a relatively high position in the rankings of scientific production in both Medicine and Public Health within the international and regional contexts, but its impact is ranked among the last countries. The production trend of both fields has increased, but public health is increasing faster. Leadership is high, but international collaboration is below expectations. Publication in high impact journals (first quartile) and articles in the set 10% most cited documents (excellence) are scarce. Thus, it may be concluded that the volume and impact of publication are not in accordance with the scientific potential of Cuban health. We recommend increasing scientific cooperation, publishing articles in high impact journals, training human resources and following the international recommendations for good editorial and scientific publication practices

Relationship among research collaboration, number of documents and number of citations. A case study in Spanish computer science production in 2000-2009.

This paper analyzes the relationship among research collaboration, number of documents and number of citations of computer science research activity. It analyzes the number of documents and citations and how they vary by number of authors. They are also analyzed (according to author set cardinality) under different circumstances, that is, when documents are written in different types of collaboration, when documents are published in different document types, when documents are published in different computer science subdisciplines, and, finally, when documents are published by journals with different impact factor quartiles. To investigate the above relationships, this paper analyzes the publications listed in the Web of Science and produced by active Spanish university professors between 2000 and 2009, working in the computer science field. Analyzing all documents, we show that the highest percentage of documents are published by three authors, whereas single-authored documents account for the lowest percentage. By number of citations, there is no positive association between the author cardinality and citation impact. Statistical tests show that documents written by two authors receive more citations per document and year than documents published by more authors. In contrast, results do not show statistically significant differences between documents published by two authors and one author. The research findings suggest that international collaboration results on average in publications with higher citation rates than national and institutional collaborations. We also find differences regarding citation rates between journals and conferences, across different computer science subdisciplines and journal quartiles as expected. Finally, our impression is that the collaborative level (number of authors per document) will increase in the coming years, and documents published by three or four authors will be the trend in computer science literature
