Impacto de las revistas de salud colombianas: comparación de Publindex versus Google Scholar Metrics, SciELO y SCOPUS / Impact of Colombian health journals: comparing Publindex versus Google Scholar Metrics, SciELO and SCOPUS

Rodríguez Morales, Alfonso J., Ochoa Orozco, Sergio Andrés, Mayta-Tristan, Percy 30 April 2014 (has links)
Trabajo previamente presentado en forma oral (TI-017), en parte, en el XXIV Congreso Estudiantil Colombiano de Investigación Médica (XXIV CECIM) y I Congreso Científico de COODESURIS (I CC COODESURIS), 15-18 de mayo de 2013, Pereira, Risaralda, Colombia, donde obtuvo el Premio "Segundo Lugar de Trabajos de Investigación". / The citation based indicators are recognized by the scientific community to assess the quality of scientific journals. Colombia has a rating system called the National Journal magazines Index (IBN) / Publindex. The objective of this study is to evaluate the impact of the Colombian health journals according to Google ScholarMetrics (GSM), SciELO, and SCOPUS, compared with the IBN classification for 2007-2011. In analyzing journals by GSM H index, we find that among the worst journals classified "C" by Publindex, there are publications with higher H5 index and H5 median than those top-ranked journals by IBN as "B" and "A2". There are journals such as The Colombian Anesthesiology that without being in IBN, has SciELO higher impact factor than several IBN "A1" journals. There are indexed journals in Scopus which despite being quartile 3 (Q3) are rated "A2" by IBN but they are Q4 journals classified as "A1" by IBN. This shows that Publindex classification is not consistent with journal impact indicators in three systems: GSM, Scopus, and SciELO, as it has been previously suggested by other authors. It is required to improve the Publindex classification and such classification should take into account citation and impact parameters so that the quality reflected in international indicators would be consistent with the national classification. / Revisión por pares

Scientometric analysis of the scientific research on the evaluation of the implementation of e-learning in the period 2000-2015 / Análisis cienciométrico de la producción científica acerca de la investigación sobre la evaluación de la implementación del e-learning en el periodo 2000-2015 / Análise cientométrica da investigação científica sobre a avaliação da implementação do e-learning no período 2000-2015

A documental review to provide an overview about the evaluation of implementationof e-learning beginning with the exploration in Scopus and Web of Science (WoS) from 2000 to 2015 has been carried out. It was used a methodology for analyzing scientometric with five stages: i) Recovery, ii) Migration, iii) Analysis, iv) Display and v) Interpretation. A set of 1147 records were analyzed, and, it was found that countries with the greatest contribution to research in e-learning were: the United States, Spain, UK, Australia and Germany. The study shown a range of topics related to e-learning and knowledge in different areas, but also a lack of worldwide research and Latin American authors were identified. Finally, this work will allow researchers to identify trends over the last fifteen years. / Se realiza una revisión documental para proporcionar un panorama de investigaciónsobre la evaluación de la implementación del e-learning a partir de la exploración en Scopus y Web of Science (WoS) desde el año 2000 a 2015. Se usa una metodología de análisis cienciométrico de cinco etapas: i) Recuperación, ii) Migración, iii) Análisis, iv) Visualización e v) Interpretación. Se analizó un conjunto de 1147 registros encontrándose que los países con mayor aporte fueron: Estados Unidos, España, Reino Unido, Australia y Alemania. El análisis del panorama refleja una gama de temáticas relacionadas con el e-learning y diferentes áreas del saber, también, se encontró una escasa presencia de investigación y de autores de origen latinoamericano. Este trabajo permitirá que los investigadores identifiquen tendencias de los últimos quince años. / Uma revisão da literatura para fornecer uma visão geral da pesquisa sobre a avaliação da execução do e-learning a partir da exploração no Scopus e Web of Science (WoS) desde o ano 2000 até 2015 foi feita. A metodologia usada para a análise cienciométrica tem as seguintes cinco fases: i) Recuperação, ii) Migrações, iii) Análise, iv) Visualização e v) Interpretação. Um conjunto de 1147 registros foram analisados, encontrou-se que os países com maior contribuição à pesquisa são: os Estados Unidos, a Espanha, o Reino Unido, a Austrália e a Alemanha. O trabalho mostrou uma variedade de tópicos relacionados com as diferentes áreas do conhecimento e ao e-learning, assim como, a falta de investigações ao redor do mundo, e pesquisadores na América Latina. Finalmente, o trabalho permitirá aos pesquisadores identificar tendências presentadas ao longo dos últimos quinze anos.

El aporte científico de las Universidades Públicas Mexicanas, 1972-2007

Santillán Rivero, Emma Georgina 06 September 2012 (has links)
Las universidades públicas mexicanas constituyen un eslabón fundamental para el crecimiento y desarrollo del país. Su heterogeneidad y características las convierten en entidades complejas, cambiantes, que con las nuevas tendencias y forma de evaluación deben rendir cuentas de sus logros. Considerando que la mayor actividad científica se encuentra centralizada, en esta tesis se construyeron indicadores bibliométricos para exponer la visibilidad de 62 universidades distribuidas en el interior del país. Según las publicaciones localizadas en los índices de Thomson Reuters del periodo 1972 a 2007, se identificaron 22,267 documentos que arrojaron un promedio de publicación anual de 618.52 artículos; y por universidad, 359.14. Las más productivas se concentraron en siete entidades. El 58% de los trabajos se publicaron en revistas con cuartil 1 y 2. Las áreas temáticas más estudiadas fueron Física, Química, Medicina, Ciencia de los Materiales y la Ingeniería. La correlación entre el Índice de Desarrollo Humano y la productividad no fue significativa. Finalmente, se presentan los pormenores del Factor de Impacto de las universidades por Entidad Federativa / Mexican public universities are an essential link for the growth and development. Heterogeneity and the characteristics become complex entities, changing with new trends and forms of evaluation should be held accountable for their achievements. Whereas most scientific activity is centralized in this thesis bibliometric indicators were constructed to expose the visibility of 62 universities distributed inside the country. According to publications located in the indexes of Thomson Reuters for the period 1972 to 2007, documents were identified that yielded a 22.267 average annual publication of articles 618.52, and by university, 359.14. The most productive were concentrated in seven states. 58% of the articles were published in journals with quartile 1 and 2. The thematic areas were studied Physics, Chemistry, Medicine, Materials Science and Engineering. The correlation between National Human Development Index and productivity was not significant. Finally, we present the details of the Impact Factor of universities by state.
