Understanding author choices in the current conservation publishing landscape.

Conservation literature addresses a broad spectrum of interdisciplinary questions and benefits. Conservation science benefits most when a diverse range of authors are represented, particularly those from countries where much conservation work is focused. In other disciplines, it is well known that barriers and biases exist in the academic publishing sphere, which can affect research dissemination and an author's career development. We used a discrete choice experiment to determine how 7 journal attributes affect authors' choices of where to publish in conservation. We targeted authors directly by contacting authors published in 18 target journals and indirectly via communication channels for conservation organizations. We only included respondents who had previously published in a conservation-related journal. We used a multinomial logit model and a latent class model to investigate preferences for all respondents and distinct subpopulations. We identified 3 demographic groups across 1038 respondents (older authors from predominantly middle-income countries, younger authors from predominantly middle-income countries, and younger authors from high-income countries) who had published in conservation journals. Each group exhibited different publishing preferences. Only 2 attributes showed a consistent response across groups: cost to publish negatively affected journal choice, including authors in high-income countries, and authors had a consistent preference for double-blind review. Authors from middle-income countries were willing to pay more for society-owned journals, unlike authors from high-income countries. Journals with a broad geographical scope that were open access and that had relatively high impact factors were preferred by 2 of the 3 demographic groups. However, journal scope and open access were more important in dictating journal choice than impact factor. Overall, different demographics had different preferences for journals and were limited in their selection based on attributes such as open access policy. However, the scarcity of respondents from low-income countries (2% of respondents) highlights the pervasive barriers to representation in conservation research. We recommend journals offer double-blind review, reduce or remove open access fees, investigate options for free editorial support, and better acknowledge the value of local-scale single-species studies. Academic societies in particular must reflect on how their journals support conservation and conservation professionals.

Comprensión de las elecciones de los autores en el entorno actual de publicaciones sobre la conservación Resumen La bibliografía sobre conservación aborda un amplio espectro de preguntas y beneficios interdisciplinarios. La mayor parte de ella representa una gama diversa de autores, sobre todo de países en los que se centra gran parte del trabajo de conservación. Es bien sabido que en otras disciplinas existen barreras y sesgos en el ámbito de la publicación académica que pueden afectar a la difusión de la investigación y al desarrollo de la carrera de un autor. Usamos un experimento de elección discreta para determinar cómo afectan siete atributos de las revistas sobre conservación en la elección de los autores sobre en cuál publicar. Nos dirigimos directamente a los autores y nos pusimos en contacto con quienes publicaban en 18 revistas objetivo e indirectamente a través de los canales de comunicación de las organizaciones de conservación. Sólo incluimos a los encuestados que habían publicado anteriormente en una revista relacionada con la conservación. Usamos un modelo logit multinominal y un modelo de clases latentes para investigar las preferencias de todos los encuestados y de las distintas subpoblaciones. Identificamos tres grupos demográficos entre los 1038 encuestados (autores de más edad de países con predominancia de ingresos medios, autores más jóvenes de países con predominancia de ingresos medios y autores más jóvenes de países con ingresos altos) que habían publicado en revistas de conservación. Cada grupo mostraba preferencias editoriales diferentes. Sólo dos atributos mostraron una respuesta coherente en todos los grupos: el costo de la publicación afectaba negativamente a la elección de la revista, incluidos los autores de países con ingresos altos, y los autores tenían una preferencia coherente por la revisión doble ciego. Los autores de países con ingresos medios están dispuestos a pagar más por las revistas pertenecientes a la sociedad, a diferencia de los autores de países de ingresos altos. Dos de los tres grupos demográficos prefieren las revistas de ámbito geográfico amplio, de acceso abierto y con un factor de impacto relativamente alto. Sin embargo, el alcance de la revista y el acceso abierto fueron más importantes que el factor de impacto. En general, los distintos grupos demográficos tenían preferencias diferentes en cuanto a las revistas y su selección se veía limitada por atributos como la política de acceso abierto. No obstante, la falta de encuestados procedentes de países con bajos ingresos (2% de los encuestados) destaca las barreras generalizadas para la representación en la investigación sobre conservación. Recomendamos que las revistas ofrezcan revisiones doble ciego, reduzcan o eliminen las tarifas de acceso abierto, investiguen opciones de apoyo editorial gratuito y reconozcan mejor el valor de los estudios de una sola especie a escala local. Las sociedades académicas, en particular, deben reflexionar sobre la forma en que sus revistas apoyan la conservación y a los profesionales de la conservación.

Scientific output after the 2017, 2019 and 2021 meetings of the Sociedad Española de Neonatología.

INTRODUCTION: The sharing of research findings through communications at congresses and publications is essential for the dissemination of scientific knowledge. The aim was to determine the percentage of communications presented the biennial meetings of the Sociedad Española de Neonatología (SENeo, Spanish Society of Neonatology) eventually published as full-text articles in indexed peer-reviewed journals and their bibliometric characteristics. MATERIAL AND METHODS: We conducted a cross-sectional study by reviewing the abstracts from the oral communications (OCs) in the 2017, 2019 and 2021 SENeo congresses. Then we searched for the authors in the MEDLINE and Scopus databases. We collected data on the authors, type of OC and bibliometric characteristics. RESULTS: The sample included 525 OCs, and we found a publication rate of 40.38% corresponding to 212 publications, 78.8% of them in international journals. The most frequent journal of publication was Anales de Pediatría. The median and interquartile range values for the impact factor, quartile and number of citations were 2.86 (1.96-3.98), 2 (1-3) and 3 (0-7), respectively, with a remarkable increase in the impact factor for the most recent congresses. The median time elapsed to publication was 10 months (IQR, 1-23). The proportion published was higher for multicentre studies and those with a respiratory topic. CONCLUSIONS: The frequency of publication for OCs submitted to SENeo congresses was similar to the frequency of publication for other paediatric congresses, with an impact factor that was above the mean of the congresses under study. The proportion of publication was higher for studies with a multicentre design or a respiratory topic.

Estudios bibliométricos. Una opción para desarrollar investigación en cirugía y disciplinas afines

La bibliometría es la aplicación de métodos estadísticos para analizar libros, artículos y otras publicaciones, especialmente científicos. Muy relacionada con la cienciometría e informetría, al punto de superponerse y confundirse. La bibliometría se refiere al estudio de la dinámica de las disciplinas reflejado en la producción de su literatura. Incluye desde el registro de cambios en la producción de una disciplina académica a lo largo del tiempo y entre países, hasta el problema de la colección bibliotecaria. En este artículo se explicarán algunos conceptos históricos, definiciones y objetivos de la bibliometría; así como las Leyes de la bibliometría; los tipos de análisis e indicadores bibliométricos más utilizados; para terminar con algunos ejemplos de diferentes tipos de estudios bibliométricos publicados, para que el lector pueda formarse una idea general de lo que puede hacer en este campo, aplicando estas metodologías a disciplinas quirúrgicas y otras también. El objetivo de este manuscrito fue generar un documento de estudio respecto de la bibliometría como alternativa para desarrollar investigación en cirugía y disciplinas afines.

Bibliometrics is the application of statistical methods to analyze books, articles and other publications, especially scientific ones. Closely related to scientometrics and informetrics, to the point of overlapping and confusing. Bibliometrics refers to the study of the dynamics of the disciplines reflected in the production of their literature. It includes everything from the record of changes in the production of an academic discipline over time and between countries or regions, to the problem of the library collection. In this article some historical concepts, definitions and objectives of bibliometrics will be explained; as well as the Laws of bibliometrics; the types of analysis and bibliometric indicators most used; to finish with some examples of different types of published bibliometric studies, so that the reader can form a general idea of what he can do in this field, applying these methodologies to surgical disciplines and others as well. The aim of this manuscript was to generate a study document regarding bibliometrics as an alternative to develop research in surgery and related disciplines.

Bibliometric analysis of the official journals of internal medicine societies in Europe.

INTRODUCTION: Bibliometrics evaluates the quality of biomedical journals. The aim of this study has been to compare the main bibliometric indexes of the official journals of scientific societies of Internal Medicine in Europe. MATERIAL AND METHODS: Bibliometric information was obtained from the Web of Science (WoS) and Scopus databases. Both impact metrics (Journal Impact Factor [JIF], CiteScore) and normalized metrics (Journal Citation Indicator [JCI], Normalized Eigenfactor, Source Normalized Impact per Paper [SNIP] and SCImago Journal Rank [SJR]) of the journals for the year 2022 were analyzed, and their evolution over the last decade was described. RESULTS: Twenty-three official journals from 33 scientific societies were evaluated. Eight journals were included in WoS and 11 in Scopus. The best positioned journals in 2022 were: 1) European Journal of Internal Medicine, which ranked in the first quartile (Q1) for JIF, CiteScore and JCI metrics, exceeding values of 1 in Normalized Eigenfactor and SNIP metrics; 2) Internal and Emergency Medicine, with Q1 for CiteScore and JCI metrics, and with values >1 in Normalized EigenFactor and SNIP metrics; 3) Polish Archives of Internal Medicine, with Q1 for JCI metrics; 4) Revista Clínica Española, with Q2 for JIF, CiteScore and JCI metrics; and 5) Acta Medica Belgica, with Q2 for CiteScore and JCI metrics. These journals increased their impact metrics in the last 3 years, in parallel with the COVID pandemic. CONCLUSIONS: Five official journals of European Internal Medicine societies, including Revista Clínica Española, meet high quality standards.

Association of trial characteristics with simultaneous publication and its impact on citations and mentions: a cross-sectional study.

INTRODUCTION AND OBJECTIVES: Randomized trials are often presented at medical conferences and published simultaneously or later. Predictors of simultaneous publication and its consequences are undetermined. Our aim was to characterize the practice of simultaneous publication, identify its predictors, and evaluate its impact. METHODS: In this cross-sectional study, we included randomized trials presented at late-breaking science sessions of major cardiovascular conferences from 2015 to 2021. The association of trial characteristics with the timing of publication was analyzed. The impact of simultaneous vs nonsimultaneous publication was investigated on the number of 1-year citations and 1-month mentions, and the total citations and mentions at the longest observation follow-up. RESULTS: Of 478 trials included in the analysis, 48.7% were published simultaneously. Simultaneous publications were more likely to be presented in the main conference room (OR, 6.09; 95%CI, 1.34-36.92; P=.029) and were characterized by a shorter review time (OR, 0.95; 95%CI, 0.91-0.96; P<.001). Simultaneous publications were associated with higher 1-year citations (R2, 43.81; 95%CI, 23.89-63.73; P<.001), 1-month mentions (R2, 132.32; 95%CI, 85.42-179.22; P<.001) and total citations (R2, 222.89; 95%CI, 127.98-317.80; P<.001). CONCLUSIONS: Randomized trials presented in the main conference room and with shorter review time were more likely to be published simultaneously. Simultaneous publications were associated with more citations and mentions than nonsimultaneous publications.

Actualizando el sistema; capitalismo cognitivo y semiocapitalismo / Updating the System; Cognitive Capitalism and Semiocapitalism

El conocimiento en las sociedades digitalizadas se torna aceleradamente efímero, obsolescente y competitivo. Así, los roles de sus académicos se ven sometidos a una existencia precaria; se esfuerzan por acumular capital semiótico a través de factores de impacto ­fácilmente cuantificables­ que desdibujan el valor cualitativo de lo cognitivo. Es en esta trama que terminan inscribiéndose las universidades del siglo XXI; la mayéutica de Akádêmos comienza a desdibujarse tras la competitividad burocrático-empresarial del capitalismo cognitivo

Knowledge in digitized societies rapidly becomes ephemeral, obsolescent and competitive. Thus, the roles of its academics are subjected to a precarious existence; they strive to accumulate semiotic capital through impact factors ­ easily quantifiable ­ that blur the qualitative value of the cognitive. It is in this plot that the universities of the XXI century end up registering; Akádêmos's maieutics begins to blur behind the bureaucratic-business competitiveness of cognitive capitalism

Significado de la indexación de la Revista Peruana de Ginecología y Obstetricia a Scopus

La Revista Peruana de Ginecología y Obstetricia (RPGO) ha obtenido su inclusión en la importante base de datos Scopus. En una rápida recopilación de la publicación de la revista, se recuerda la dedicación editorial de sus seis editores, cuatro de los cuales acababan de presidir la Sociedad Peruana de Obstetricia y Ginecología (SPOG). Los momentos iniciales de trabajo editorial fueron realizados manualmente, en máquinas de escribir y visitando la imprenta continuamente, así como a los patrocinadores. El compromiso de los Comités Directivos de SPOG para financiar la publicación y distribución de los ejemplares permitió la gradual indexación a bases de datos locales, regionales e internacionales. Su internalización se amplió desde la publicación de la RPGO en el Open Journal Systems (OJS), sistema informático donde se publica los artículos con puntualidad, calidad, incluyendo sus características editoriales y la Información para los Autores. Ahora la publicación es solo virtual, en español e inglés, con visibilidad e impacto de los artículos desde el inicio de la RPGO en 1955. Con datos actualizados del OJS sobre la RPGO, el número de visitas mensuales a los resúmenes llegan hasta 10 mil y las descargas mensuales de artículos en formato PDF hasta más de 9 mil. Y, en el ámbito de revistas científicas de ginecoobstetricia de América Latina y España en Scopus, destaca el índice h de la RPGO por Google Scholar Metrics, como una de las mejores. Al presente, y frente a los desafíos futuros, la actividad de la RPGO ha sido fortalecida, estableciendo un equipo editorial y herramientas que permiten la ya iniciada profesionalización de los procesos de la actividad editorial.

The Peruvian Journal of Gynecology and Obstetrics (RPGO, for its acronym in Spanish) has obtained its inclusion in the important Scopus database. A quick review of the journal's publication recalls the editorial dedication of its six editors, four of whom had just recently chaired the Peruvian Society of Obstetrics and Gynecology (SPOG, for its acronym in Spanish). The initial editorial work was carried out manually, on typewriters and continuously visiting the printing press, as well as the sponsors. The commitment of the SPOG Steering Committees to finance the publication and distribution of the issues allowed the gradual indexing to local, regional and international databases. Its internalization was expanded since the publication of the RPGO in the Open Journal Systems (OJS), a computer system where articles are published with punctuality, quality, including their editorial characteristics and the Information for Authors. Now the publication is only virtual, in English and Spanish, with visibility and impact of the articles since the beginning of the RPGO in 1955. With updated OJS data on the RPGO, the number of monthly visits to the abstracts reaches up to 10 thousand and monthly downloads of articles in PDF format reach more than 9 thousand. And, in the field of obstetrics and gynecology scientific journals in Latin America and Spain in Scopus, the h index of the RPGO by Google Scholar Metrics stands out as one of the best. At present, and facing future challenges, the activity of the RPGO has been strengthened, establishing an editorial team and tools that allow the already initiated professionalization of the processes of the editorial activity.

Scientific authorship in neurosurgery.

INTRODUCTION: Assessment of scientific bibliographic production is a complex issue, mainly based on the impact factor (IF) of the journals and the h index, that quantifies the number of cites an author receives. In order to estimate the bibliographic production and the influence of co-authorship among Spanish neurosurgeons, we performed a PubMed search aimed to identify all papers published by a sample of neurosurgeons. METHODS: Cross-sectional observational and regional study. We identified a sample of 183 neurosurgeons from Madrid and Castilla y León Autonomous Communities. The bibliometric information was gathered in March 2022 via PubMed free access website. For each author we registered the type of journal, total number of articles, order of appearance in the authors' list, total IF, the proportion of articles signed as first or second author (Personal Authorship Quotient [PAQ]) and the percentage of IF attributable to those articles (Personal Impact Quotient [PIQ]). RESULTS: A total of 3,592 articles from 183 authors were published in 412 different journals, of which only 9.9% were pure neurosurgical journals. Only 17 neurosurgeons (9,3%) had published at least one article as unique author. The average number of articles per neurosurgeon was 20 (median 9) of which 57.7% were published in neurosurgical journals, and 22,2% in Neurocirugía (official publication of the SENEC). The average PAQ was 0.367 (median 0.364) and the average PIQ was 0.317 (median 0.251). Both proportions tended to decrease as the number of publications increased. CONCLUSIONS: On average, Spanish neurosurgeons publish half of their articles in neurosurgical journals, appear as first or second author in one third of the cases, and the IF attributable to these papers comprise 25% of the total IF. The PAQ and PIQ provide bibliometric information that minimizes the enlarging effect on curriculum of massive co-authorship and allow comparisons among authors and different scientific fields.

Conclusions: The volume of information published on COVID-19 and the citations received influenced the impact increase in 2021 JCR.

Relación entre la cuenta de Twitter @ascolcirugia y las publicaciones de la Revista Colombiana de Cirugía durante la pandemia / Relationship between the Twitter account @ascolcirugia and the publications of the Colombian Journal of Surgery during the pandemic

Introducción. Indicadores alternativos basados en la web 2.0 han tomado importancia para medir el impacto de la producción científica. Previamente se han demostrado correlaciones positivas entre indicadores tradicionales y alternativos. El objetivo de este trabajo fue evaluar la relación de estos indicadores en el campo de la cirugía de nuestro país.Métodos. Análisis retrospectivo de las publicaciones de la Revista Colombiana de Cirugía y "tweets" de la cuenta @ascolcirugia entre marzo 2020 y julio 2021. Se evaluaron comparativamente los artículos con y sin publicación en la cuenta @ascolcirugia. Se determinó la correlación entre indicadores alternativos e indicadores tradicionales de las publicaciones de la revista. Resultados. En total se revisaron 149 artículos y 780 "tweets"; tan sólo el 13,4 % (n=20) de los artículos tuvieron visibilidad en la cuenta @ascolcirugia, con una mediana de 2 "tweets" (RIQ 1-2) por artículo, siendo la mayoría de estos sobre temas de COVID-19 (85 % vs 10 %; p<0,001). Los artículos publicados en @ascolcirugia tuvieron una mayor mediana de descargas (220 vs 116; p<0,001) y citaciones (3,5 vs 0; p<0,001) en comparación con los que no fueron publicados.Conclusión. El uso de las redes sociales tiene un efecto positivo en el número de lectores de la Revista Colombiana de Cirugía y el impacto académico de los autores. Aunque existe una buena correlación entre indicadores alternativos y tradicionales en el contexto nacional, la proporción de artículos de la Revista Colombiana de Cirugía publicados en la cuenta @ascolcirugia es baja.

Introduction. Alternative indicators based on web 2.0 have gained great relevance to measure the impact of scientific production. Positive correlations between traditional and alternative indicators have previously been shown. The objective of our article is to evaluate the relationship of these indicators in the field of surgery in our country.Methods. Retrospective analysis of the publications of the Colombian Journal of Surgery and tweets of the Twitter account (@ascolcirugia) during March 2020 and July 2021. Articles with and without tweets in the account @ascolcirugia were comparatively evaluated. The correlation between alternative indicators and traditional indicators of the journal's publications was determined. Results. A total of 149 articles and 780 tweets were reviewed; only 13.4% (n=20) of the articles had visibility at the @ascolcirugia account, with a median of 2 tweets (RIQ 1-2) per article, most of which were on COVID-19 issues (85% vs 10%; p<0.001). The articles published at the @ascolcirugia account had a higher median number of downloads (220 vs 116; p<0.001) and citations (3.5 vs 0; p<0.001) compared to the articles that were not published. Conclusions. The use of social media has a positive effect on the number of readers of the Colombian Journal of Surgery and the academic impact of the authors. Although there is a good correlation between alternative and traditional indicators, in the national context, the proportion of articles of the Colombian Journal of Surgery published at the @ascolcirugia account is low

Métricas de impacto y evaluación de la ciencia / Impact metrics and science evaluation

RESUMEN Los científicos siempre buscaron formas de evaluar los resultados de las investigaciones para reconocer y premiar sus esfuerzos, y para apoyar decisiones en programas y políticas públicas. Las medidas o métricas de impacto de la ciencia se transformaron, en las últimas décadas, en el motor propulsor del ambiente académico. Investigadores, revistas científicas, bases de datos y casas editoriales, instituciones de investigación y agencias de financiación tienen su trabajo gobernado por el impacto de la investigación que producen, publican, indexan, promueven y financian. Se utilizan largamente indicadores bibliométricos para la evaluación de la producción científica, a pesar de la falta de relación inequívoca entre citas y calidad, impacto o mérito científico. Además, cuando se considera la innovación, característica inherente de la investigación científica, la relación es todavía más desconectada. En este artículo se describen los tipos principales de métricas utilizadas para evaluar la producción científica, sus características, potenciales y limitaciones.

ABSTRACT Scientists have always looked for ways to evaluate research results to recognize and reward their efforts, and to support decisions regarding programs and public policies. The metrics of scientific impact have become, in recent decades, the driving force behind the academic environment. The work of researchers, scientific journals, databases and publishers, research institutions, and funding agencies is driven by the impact of the research they produce, publish, index, promote and finance. Bibliometric indicators are widely used for the evaluation of scientific output, despite the lack of a clear relationship between citations and quality, impact, or scientific merit. Furthermore, the relationship is even less evident regarding innovation, which is an inherent characteristic of scientific research. This article describes the main types of metrics used to evaluate scientific output, as well as its features, potentials, and limitations.

Indicadores bibliométricos: impacto y altmetrics para una evaluación amplia y equitativa de las revistas científicas de Colombia / Bibliometrics Indicators: Impact and Altmetrics for an Extensive and Equitable Assessment of Colombian Scientific Journals / Indicadores bibliométricos: impacto e altmetria para uma avaliação ampla e equitativa das revistas científicas colombianas

La medición y análisis de la calidad de las publicaciones científicas es de fundamental importancia para evaluar el progreso e impacto de investigadores, grupos de investigación y revistas científicas en la comunidad académica y la sociedad (1,2). Tradicionalmente, la evaluación se encomendaba a pares de reconocida trayectoria, idoneidad y prestigio. Sin embargo, para eliminar subjetividades, desde hace varios años se ha recurrido a indicadores bibliométricos que propenden por una calificación mensurable, objetiva y multidimensional (1,3). Los indicadores bibliométricos (IB) pueden definirse como cuantificadores de información bibliográfica, disponible en documentos científicos y académicos, susceptible de ser analizada en términos de producción y consumo (1,2). Existe una variada tipología de IB (1,2) en función del objeto a examinar (investigador, revista o grupo de investigación) y que en algunos casos son transversales a este. Así, los indicadores personales (edad, sexo y antecedentes de los autores) solo aplican a investigadores o grupos, mientras que los de productividad e impacto aplican también a revistas. Para estas, el indicador de productividad (cantidad) y, aún más, el de impacto ("calidad") son rutinariamente empleados para clasificarlas y compararlas con el propósito, cada vez más controversial, de medir su pertinencia y relevancia académica y/o social (4).

Measuring and analyzing the quality of scientific publications is fundamentally important for assessing the progress and impact of researchers, research groups and scientific journals in the academic community and society (1,2). Traditionally, this assessment was entrusted to peers with a recognized track record, eligibility and prestige. However, bibliometric indicators have been used for several years to eliminate subjectivity, which aim at a measurable, objective and multi-dimensional qualification (1,3). Bibliometric indicators (BI) can be defined as quantifiers of the bibliographic information available in scientific and academic documents susceptible to being analyzed in terms of production and consumption (1,2). There is a typological variety of BI (1,2) based on the object to be examined (researcher, journal or research group) and, in some cases, they are cross-sectional to it. In this way, personal indicators (age, gender and background of the authors) only apply to researchers or groups, while productivity and impact also apply to journals. For journals, the productivity (quantity) and, more so, impact ("quality") indicators, are routinely used to classify journals and compare them, with the increasingly controversial purpose of measuring their academic and/or social pertinence and relevance (4).

A medição e análise da qualidade das publicações científicas é de fundamental importância para avaliar o progresso e o impacto de pesquisadores, grupos de pesquisa e revistas científicas na comunidade acadêmica e na sociedade (1,2). Tradicionalmente, a avaliação era confiada a pares de reconhecida trajetória, idoneidade e prestígio. No entanto, a fim de eliminar subjetividades, há vários anos são utilizados indicadores bibliométricos que visam uma qualificação mensurável, objetiva e multidimensional (1,3). Indicadores bibliométricos (IB) podem ser definidos como quantificadores de informações bibliográficas, disponíveis em documentos científicos e acadêmicos, passíveis de análise em termos de produção e consumo (1,2). Existe uma tipologia de IB variada (1,2) dependendo do objeto a ser examinado (pesquisador, periódico ou grupo de pesquisa) e que em alguns casos são transversais a ele. Assim, os indicadores pessoais (idade, sexo e formação dos autores) se aplicam apenas a pesquisadores ou grupos, enquanto os de produtividade e impacto também se aplicam a periódicos. Para estes, o indicador de produtividade (quantidade) e, mais ainda, o indicador de impacto ("qualidade") são rotineiramente utilizados para classificá-los e compará-los com o propósito cada vez mais controverso de medir sua pertinência e relevância acadêmica e/ou social (4).

Cuba Publications in the Science Citation Index Expanded: publication characteristics, institutions and journals / Publicaciones de Cuba en el Science Citation Index: características de la publicación, instituciones y revistas

Abstract Introduction: In contrast with other tropical countries, Cuba has been frequently studied from the point of view of scientometrics. It has been reported that Cuban researchers often failed to cite other Cuban researchers or to collaborate with them and that 78 % of the Cuban scientific output is published in Cuban journals and mostly missed by Scopus and the Web of Science. However, there are no recent comprehensive studies of science in Cuba. Objective: To quantify the Cuban scientific output, in all disciplines, until the beginning of 2021. Methods: We analyzed publications from Cuba, dated 1900 to 2021, that reached the index Science Citation Index Expanded. Results: We retrieved a total of 23 576 publications, mostly articles. In this particular database, English is the dominant language, and, over time, articles have become longer and increased the number of authors and references. Numerically, the leading institution is Universidad de La Habana. Research is strongly concentrated around medical subjects. Collaboration teams led by foreign authors have more citations recorded by the database, where the number of Cuban articles has decreased strongly since 2008. Conclusion: Our conclussions only apply to the fraction of Cuban science covered by the Science Citation Index Expanded (under 22 %). We recommend three main improvements: to increase collaboration among Cuban scientists; to expand research areas beyond medical subjects; and to improve the quality of Cuban journals.

Resumen Introducción: A diferencia de otros países tropicales, Cuba ha sido frecuentemente estudiada desde el punto de vista de la cienciometría. Se ha informado que los investigadores cubanos citan poco a otros investigadores cubanos, no colaboraron entre sí, y que el 78 % de la producción científica cubana se publica en revistas cubanas sin llegar a Scopus y la Web of Science. Sin embargo, no existen estudios recientes y generales de la ciencia en Cuba. Objetivo: Cuantificar la producción científica cubana, en todas las disciplinas, hasta inicios de 2021. Métodos: Analizamos publicaciones con dirección autoral de Cuba, fechadas de 1900 a 2021, únicamente en el Science Citation Index Expanded. Resultados: Hallamos 23 576 publicaciones, en su mayoría artículos. En esta base de datos en particular, el inglés es el idioma dominante y, con el tiempo, los artículos se han vuelto más largos y han aumentado el número de autores y referencias. Numéricamente, la institución líder es la Universidad de La Habana. La investigación se concentra fuertemente en temas médicos. Los equipos de colaboración dirigidos por autores extranjeros tienen más citas registradas en esta base de datos estadounidense, donde el número de artículos cubanos ha disminuido fuertemente desde 2008. Conclusión: Nuestras conclusiones solo se aplican a la fracción de la ciencia cubana cubierta por el Science Citation Index Expanded (menos del 22 %) . Recomendamos tres mejoras principales: incrementar la colaboración entre los científicos cubanos; ampliar las áreas de investigación más allá de los temas médicos; y mejorar la calidad de las revistas cubanas.

Caracterización de la publicación científica de docentes de enfermería en una universidad privada: análisis bibliométrico / Characterization of the scientific publications of nursing teachers of a private university: bibliometric analysis / Caracterização da publicação científica de docentes de enfermagem de uma universidade privada: análise bibliométrica

RESUMEN Introducción El número de citas que recibe un artículo publicado es una de las formas en las que se visibiliza la producción científica de una disciplina; en un contexto institucional es un camino a través del cual las universidades dan seguimiento a los artículos publicados por su personal docente.

ABSTRACT Introduction The number of citations that a published article receives is one form to visualize a discipline's scientific production. These citations represent a form for universities to follow up on the articles published by their teaching staff within an institutional context. Objective To characterize the citations of the articles published by nursing teachers of a private university in the city of Medellin, Colombia. Methods This is a descriptive and exploratory study. Articles published by the nursing teachers were reviewed. The study variables included the characteristics of the published articles and the journals where the publications have been cited. Tracking of the citations was conducted on the Google Academic, Science Direct, and Scopus databases. The information was analyzed through univariate descriptive statistics. Results 52 articles were reviewed. From these, 29 have been cited at least once. A total of 188 citations were recorded. Of these, 31 % are concentrated in 3 articles. The most cited articles were those with topics related to addictions, with 21 % of the total citations. The most cited article had 28 citations. Of the total citations, 41.5 % come from gray literature. Discussion The findings related to the bibliographical citations have relevance from various perspectives. The social and academic perspectives allow a different dimension of knowledge to overcome the plain vision of citation counting. Conclusions The level of citations given to the publications of the studied nursing teachers is low. It is important to continue carrying out studies related to publication production tracking.
