ABSTRACT
Abstract Introduction: Bibliometric analyses of research in Sri Lanka, a lower-middle income island nation in South Asia, has focused mainly on medical research, concluding that there is a need for increased research productivity and impact, and for local solutions to health concerns. There has been no general bibliometric analysis across scientific disciplines in the nation, or any study that covers a long period of time to identify general time trends. Objective: To measure and analyse Sri Lanka research by focusing on subjects, authors, institutions, journals and citation for half a century. Methods: We used an advanced search method to extract publications with the word "Sri Lanka" in the SCI-EXPANDED, and calculated indicators such as total citations from Web of Science Core Collection since publication year to the end of 2019, citations in 2019, and mean citations per publication. Journal data were taken from 2019 Journal Citation Report. Affiliation re-classification was done to ensure consistency regarding the origin of all publications. Publications were further analysed based on collaboration, and first and corresponding authorship. Results: We retrieved 16 069 publications in 19 document types (77 % articles). Corrections had the highest number of authors per publication (616) followed by articles (116). Four articles had more than 5 000 authors and 593 articles had more than 1 000 authors. The highest citations in this database were for international megaprojects where Sri Lanka authors played minor roles. The UK had the most collaborative articles with Sri Lanka (19 %). The articles were published in 3 051 journals across 177 Web of Science categories. The category of Public, environmental and occupational health, with 193 journals, had 6.7 % of all articles, followed by environmental sciences (6.6 %). Conclusion: Sri Lanka has an unusually strong pattern of participating as small role players in international megaprojects about health and physics. Sri Lanka authors should be encouraged to expand their horizons by researching non-applied fields that are the basis of all innovation; to strengthen their own journals so that they have better visibility and impact, and to improve their positions in international projects that are published in larger journals.
Resumen Introducción: Los análisis bibliométricos de la investigación en Sri Lanka, una nación insular de ingresos mediano-bajos en el sur de Asia, se han centrado principalmente en la investigación médica, concluyendo que existe la necesidad de aumentar la productividad y el impacto de la investigación, y de soluciones locales a los problemas de salud. No ha habido un análisis bibliométrico general de disciplinas científicas o algún estudio que cubra un período largo de tiempo para identificar tendencias generales. Objetivo: Medir y analizar la investigación de Sri Lanka centrándose en temas, autores, instituciones, revistas y citas, durante medio siglo. Métodos: Utilizamos un método de búsqueda avanzada para extraer publicaciones con las palabras "Sri Lanka" en el SCI-EXPANDED, y calculamos indicadores como el total de citas de Web of Science Core Collection desde el año de publicación hasta finales de 2019, citas solo en 2019, y media de citas por publicación. Los datos de revistas son del Journal Citation Report 2019. Revisamos manualmente las afiliaciones para garantizar su coherencia, y, de todos los tipos de publicación, analizamos en detalle los artículos en función de la colaboración y la autoría. Resultados: Hallamos 16 069 publicaciones en 19 tipos de documentos (77 % artículos). Las correcciones tuvieron el mayor número de autores por publicación (616), seguidas de los artículos (116 autores en promedio); cuatro artículos tenían más de 5 000 autores y 593 artículos tenían más de 1 000 autores. Las citas más altas en esta base de datos fueron para megaproyectos internacionales en los que los autores de Sri Lanka desempeñaron papeles menores. El Reino Unido tuvo más artículos colaborativos con Sri Lanka (19 %). Los artículos se publicaron en 3 051 revistas de 177 categorías del Web of Science. La categoría d Salud pública, ambiental y ocupacional, con 193 revistas, tuvo el 6.7 % del total de artículos, seguida de Ciencias ambientales (6.6 %). Conclusión: En Sri Lanka hay una tendencia inusual a participar como pequeños actores en megaproyectos internacionales sobre salud y física. Debería alentarse a quienes hacen ciencia en Sri Lanka a ampliar sus horizontes investigando campos no aplicados, que son la base de la innovación; a fortalecer sus propias revistas para lograr mayor visibilidad e impacto, y a mejorar su ubicación en proyectos internacionales que se publican en revistas más grandes.

ABSTRACT
Resumen Camerún es uno de los seis países de África Central con más de 20 millones de habitantes. Para caracterizar el desempeño de la investigación de Camerún, las publicaciones de los Camerúnes en el Science Citation Index Expanded durante el período de 1936-2015, indexadas en la base de datos Thomson Reuters SCI-EXPANDED, fueron estudiadas en este trabajo. Todos los documentos de ese período con Camerún en el campo de dirección fueron incluidos en el estudio. Se analizaron el tipo de documento, el idioma, la tendencia y las colaboraciones, así como el resultado de diferentes categorías de temas. También se analizaron las interpretaciones de los países, instituciones y autores, incluyendo el total, único, colaborativo, primer autor, y publicaciones de autor correspondientes. Los artículos fueron analizados por la producción científica y los resultados de investigación de individuos, instituciones y países colaborativos con Camerún. Los análisis incluyeron 8 457 artículos (85 % de 10 591 publicaciones de Camerún). Estos análisis bibliométricos de las publicaciones camerunesas aportaron ideas interesantes sobre autores, instituciones y modelos de colaboración. Los resultados mostraron que la investigación en Camerún era altamente dependiente de colaboraciones extranjeras, y la colaboración internacional fue responsable del creciente número de publicaciones a lo largo de los años. Se encontró que los artículos con autores primarios o autores correspondientes de fuera de Camerún obtuvieron más citas que los otros y que los artículos sin ninguna colaboración internacional tenían citas más bajas. El número de artículos indexados por SCI-EXPANDED ha mostrado un aumento en términos de artículos cameruneses que es considerablemente mayor que el aumento en el número de todos los artículos en SCI-EXPANDED. Los artículos eran más frecuentes que otros tipos de publicación y en su mayor parte en inglés. La Universidad de Yaundé I ocupó el primer lugar en artículos de colaboración interinstitucional, el rango de los artículos de colaboración interinstitucional y el rango de los artículos del primer autor y los artículos de autores correspondientes. La Universidad de Yaundé I también estuvo en una posición de liderazgo absoluta desde 1970 hasta 2015, seguida muy de lejos por las otras instituciones. Las categorías de medicina tropical, ciencias vegetales, salud pública ambiental y ocupacional, y enfermedades infecciosas, representaron el mayor número de artículos publicados. Aunque la física y la química dominaron el ranking de los 20 mejores autores cameruneses, un artículo independiente de matemáticas fue el más citado, con 60 citas en 2015 a un autor camerunés. Los tres principales investigadores productivos fueron: T. C. Kofane, B. T. Ngadjui, P. Woafo, todos de la Universidad de Yaundé I. Francia y Estados Unidos dominaron el ranking de países con una fuerte colaboración científica con Camerún.
Abstract Cameroon is one of the six countries of Central Africa with more than 20 000 000 residents. To characterize the Cameroon research performance, Cameroonians publications in the Science Citation Index Expanded during the period of 1936-2015, indexed in the Thomson Reuters SCI-EXPANDED database, were studied in this work. All documents of that period with Cameroon in the address field were included in the study. The document type, language, trend and collaborations were analyzed, as well as the output of different subject categories. Performances of countries, institutions and authors, including total, single, collaborative, first author, and corresponding author publications were also analyzed. Articles were analyzed by the scientific output and research performances of individuals, institutions and collaborative countries with Cameroon. Analyses included 8 457 articles (85 % of 10 591 Cameroonian publications). These bibliometric analyses of Cameroonian publications provided interesting insights concerning authors, institutions and collaboration patterns. Results showed that research in Cameroon was highly dependent on foreign collaborations, and the international collaboration was responsible for the increasing number of publications over the years. It was found that the articles with either first authors or corresponding authors from outside Cameroon got more citations than the others, and that the articles without any international collaboration had lower citations. The number of articles indexed by SCIEXPANDED has seen an increase in terms of Cameroonian articles that is considerably greater that the increase in number of all articles in SCI-EXPANDED. Articles were more frequent than other types of publication and they were mostly in English. The University of Yaoundé I ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. The University of Yaoundé I also was in an absolute leading position from 1970s to 2015, followed far away by the other institutions. The categories of tropical medicine, plant sciences, environmental and occupational public health, and infectious diseases, represented the largest number of published articles. Even though physics and chemistry dominated the ranking of the top 20 best Cameroonian authors, an independent mathematics article was the most cited, with 60 citations in 2015 to a Cameroonian author. The top three productive researchers were T. C. Kofane, B. T. Ngadjui, P. Woafo, all from University of Yaoundé I. France and the USA dominated the ranking of countries with strong scientific collaboration with Cameroon.
ABSTRACT
Las publicaciones sobre la epidemiología de Giardia en humanos de Argentina se hallan dispersas en numerosas fuentes de información, lo que dificulta su acceso y visibilidad para la comunidad científica. El objetivo de este trabajo fue realizar un análisis bibliométrico cuantitativo de la producción científica sobre Giardia en humanos de Argentina durante el período 1995-2014. El volumen de publicaciones científicas hallado fue igual a 112 (36 artículos, 73 comunicaciones y 3 tesis). La distribución idiomática mostró un predominio del español. Los artículos fueron publicados en 25 revistas de América, Europa y Asia. Este estudio bibliométrico demostró un incremento del volumen de publicaciones sobre Giardia en Argentina durante los últimos 20 años. Los artículos mostraron un índice de colaboración entre investigadores similar a la bibliografía. El índice de institucionalidad fue elevado para instituciones nacionales, e inexistente para la colaboración internacional. La utilización de indicadores bibliométricos permite contar con una herramienta sólida para el diagnóstico y prospección de las actividades de investigación sobre epidemiología de Giardia y contribuye a la difusión y visibilidad de la información relativa a la producción científica desarrollada en Argentina.
The scientific literature on Giardia epidemiology in humans from Argentina is scattered in numerous sources, making it difficult to access them and provide visibility to the scientific community. The aim of this study was to perform a quantitative bibliometric analysis of the scientific production on Giardia in humans from Argentina during the 1995-2014 period. The volume of scientific literature was 112 (36 articles, 73 communications, and 3 theses). The language distribution showed a predominance of Spanish. The articles were published in 25 journals from America, Europe and Asia. This bibliometric study showed an increased volume of publications on Giardia in Argentina during the last 20 years. The articles showed a Collaboration Index between researchers similar to the literature. The institutional Index was elevated for national institutions and non-existent for international collaboration. The use of bibliometric indicators can provide a solid tool for the diagnosis and survey of the research on epidemiology of Giardia, and it contributes to the dissemination and visibility of information on the scientific production developed in Argentina.
