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).

Influência das métricas de mídias sociais nas citações dos periódicos brasileiros de Enfermagem indexados na Scopus / The influence of social media metrics on citations of brazilian nursing journals

O uso de mídias sociais por pesquisadores, instituições, publicações e público em geral, assim como a adoção da altmetria para aferição de impacto de produtos científicos em diferentes plataformas online, vem ao encontro do que preconizam as novas propostas para a comunicação científica. A Enfermagem possui uma produção científica por vezes mais acessível à sociedade o que lhe permite alcançar um público mais amplo e diversificado, por vezes não acadêmico, que acessa, lê e discute temas que muitas vezes fazem parte do seu cotidiano. A tese justifica-se pela carência de estudos brasileiros sobre o uso de modelos, métodos e técnicas estatísticas para medir os efeitos da relação e da possibilidade de usar métricas de mídias sociais para prever o volume de citações de artigos científicos da Enfermagem. Estudo exploratório e de abordagem quantitativa que analisa o efeito das interações em mídias sociais nas citações de 4.776 artigos publicados em onze periódicos brasileiros do campo da Enfermagem indexados na Scopus no período de 2015 a 2019. Os dados de impacto sobre os artigos no Mendeley, Twitter e Facebook, foram fornecidos pela PlumX. Também foram coletados dados altmétricos do corpus nas contas das revistas no Facebook e no Twitter. Para predição de resultados foi utilizado o modelo de regressão Binomial Negativo devido à natureza dos dados disponíveis. Foi observado que 99% do corpus estava coberto no Mendeley, 19,6% no Facebook e 12,6% no Twitter. Foi verificada uma correlação moderada (rs = 0,591, p < 0,05) entre o volume de leitores no Mendeley e o volume de citações na Scopus Os resultados demonstraram uma correlação nula entre as interações recebidas pelos artigos no Facebook (rs = - 0,129, p < 0,05) e no Twitter (rs = 0,141, p < 0,05) com as citações recebidas pelos artigos na Scopus. O modelo de regressão demonstrou que para cada aumento no número leitores em um artigo no Mendeley, mantendo-se outros parâmetros fixos, tem-se um aumento aproximado de 0,7% no número de citações deste artigo na Scopus. Já para cada aumento na variável ano, mantendo os outros parâmetros fixos, tem-se aproximadamente 39,8% de aumento no número de citações recebidas por um artigo na Scopus. Foram postados no Facebook pelos periódicos da Enfermagem 31,3% dos artigos publicados em 2019. O modelo de regressão demonstrou que para cada aumento no número de interações em um artigo no Facebook, mantendose os outros parâmetros fixos, tem-se um aumento médio de 2,2% no número de citações na Scopus. Foram divulgados no Twitter 16,9% dos artigos publicados pelos periódicos em 2019. Ficou evidenciada a natureza díspar do tipo de impacto que é mensurado pelas métricas tradicionais, baseadas em citações, e as métricas alternativas, percebidas em mídias sociais. Reafirma-se o que já foi exposto na literatura: a altmetria pode ser utilizada para complementar, mas não para substituir, o impacto medido pelas métricas tradicionais baseadas em citações formais, permitindo observar de forma mais ampliada como se dão os processos da comunicação científica em ambientes online informais.

The use of social media by researchers, institutions, publications and the general public, as well as the adoption of altmetrics to measure the impact of scientific products on different online platforms, is in line with the new proposals for scientific communication. Nursing has a scientific production that is sometimes more accessible to society, which makes it possible to reach a broader and more varied audience, sometimes non-academic, that accesses, reads and discusses topics that are often part of their daily lives. The dissertation is justified by the lack of Brazilian studies about the use of models, methods and statistical techniques to measure the effects of the relationship and the possibility of using social media metrics to predict the amount of citations of scientific articles in Nursing. This is an exploratory study with a quantitative approach, which analyzes the effect of interactions in social media on the citations of 4,776 articles published in eleven Nursing Brazilian journals indexed in Scopus from 2015 to 2019. PlumX provided the impact of data sharing on articles on Mendeley, Twitter and Facebook. Besides, we collected altmetric data of the corpus on Facebook and Twitter accounts of the journals. To predict the results, we used the Negative Binomial regression model due to the nature of the available data. We found that Mendeley covers 99% of the corpus; Facebook, 19.6% and Twitter, 12.6%. We found a moderate correlation (rs = 0.591, p < 0.05) between the amount of Mendeley readers and the amount of Scopus citations. The results showed a null correlation between the interactions received by the articles on Facebook (rs = - 0.129, p < 0.05) and on Twitter (rs = 0.141, p < 0.05) with the citations received by the articles in Scopus. The regression model showed that for each increase in the number of readers of an article on Mendeley, other parameters remaining fixed, there is an approximate increase of 0.7% in the number of citations of this article in Scopus. For each increase in the variable 'year', other parameters remaining fixed, there is an increase of approximately 39.8% in the number of citations received by an article in Scopus. Nursing journals posted on Facebook 31.3% of the articles published in 2019. The regression model showed that for each increase in the number of interactions in an article on Facebook, other parameters remaining fixed, there is an average increase of 2.2% in the number of citations in Scopus. Twitter posted 16.9% of the articles published by journals in 2019. It is evident the unequal nature of the type of impact that is measured by traditional metrics, based on citations, and alternative metrics, noticed on social media. We reaffirm what literature has already exposed: altmetrics can be used to complement, but not to replace, the impact measured by traditional metrics based on formal citations, allowing a broader perspective of how scientific communication processes take place in informal online environments.

Simbiosis entre indicadores bibliométricos y alternativos para un índice métrico integrado / Symbiosis of bibliometric and alternative indicators for an integrated metric index

RESUMEN Resulta un gran desafío encontrar una vía que le otorgue un valor real a las publicaciones científicas desde su impacto y calidad. Esta realidad exige el uso de indicadores bibliométricos y más reciente, algunos alternativos para la evaluación, tanto de los autores como de sus publicaciones. En este sentido se realiza un estudio de ambos sistemas de indicadores y sus metodologías, desde el análisis de debilidades y potencialidades para su integración en un único índice, de modo que permita una evaluación más integral y justa de su impacto en la comunidad científica. Se indagó además sobre la importancia, necesidad y nivel de información que se posee sobre este tema en profesores cubanos de varias universidades, durante el período 2018-2019. El objetivo del presente trabajo es argumentar algunas ideas para el acercamiento gradual del Sistema de Evaluación y Acreditación de la Educación Superior de la República de Cuba (SEAES) a estos indicadores, teniendo en cuenta el nivel de atención que reciben por bases de datos reconocidas globalmente. Los resultados son parte del proyecto de investigación El impacto social de la formación continua como parte de los procesos de mejora de la calidad en la Universidad de Camagüey.

ABSTRACT It is a great challenge to find a way that gives real value to scientific publications based on their impact and quality. This reality has required the use of bibliometric indicators and more recent some alternative ones for the evaluation of both the authors and their publications. In this sense, an analysis of both systems of indicators and their methodologies is carried out, from the analysis of weaknesses and potentialities for their integration in an only index, so that it allows a more comprehensive evaluation. and just about its impact on the scientific community. It also inquired about the importance, need and level of information that is possessed on this subject in Cuban university professors from various universities, during the period 2018-2019. The objective of the present work is to argue some ideas are proposed for the gradual approach of SEAES to these indicators, taking into account the level of attention they receive through globally recognized databases. The exposed results are part of the research project The social impact of continuous training as part of the quality improvement processes at the University of Camagüey.

Objetivo: Caracterizar la producción científica sobre COVID-19 referida a pediatria a partir de las publicaciones registradas en la base de datos Scopus, como herramienta de apoyo a la población pediátrica. Métodos: Se realizó un estudio bibliométrico descriptivo durante el período 2019-julio de 2020. Se utilizó la base datos SCOPUS. Se recuperaron 791 artículos publicados, que se exportaron a una base de datos ad hoc en EndNote X9, para su normalización y luego de un proceso de depuración la muestra final quedó conformada por 681 artículos. Se aplicaron indicadores bibliométricos para el análisis de los datos. Se emplearon los softwares Bibexcel, Vosviewery Microsoft Excel 2019, para el procesamiento, análisis y visualización de los datos. Resultados: Se identificaron los países, autores, revistas y temáticas más productivos. Se analizaron las redes de colaboración nacional e internacional y temática. Se evaluó el impacto científico y social de los artículos, mediante las citas y menciones recibidas. Predominaron las publicaciones en idioma inglés, en revistas anglosajonas con elevada visibilidad internacional e impacto en redes sociales. Conclusiones: Las publicaciones sobre COVID-19 en pediatría en Scopus, muestran un ritmo de crecimiento sostenido, no obstante, se considera insuficiente el número de artículos con tratamientos específicos para la población pediátrica(AU)

Introduction: Scientific production on COVID-19 shows a continuous and exponential growth; however, there are not bibliometric studies that had characterized it, specifically in the field of Pediatrics. Objective: To characterize the scientific production on COVID-19 referred to Pediatrics from the publications recorded in SCOPUS database, as a support tool for the pediatric population. Methods: It was conducted a descriptive bibliometric study in the period 2019 to July, 2020. It was used Scopus database. 791 published articles were recovered, and those were exported to an ad hoc database in EndNote X9 for their normalization; and after a refinement process, the final sample was formed by 681 articles. There were used bibliometric indicators for the data analysis. Softwares as Bibexcel, Vosviewer, and Microsoft Excel 2019 were used for data processing, analysis and visualization. Results: The most productive countries, authors, journals and topics were identified. There were analysed the national and international collaboration networks and the topics.

There was predominance of publications in English language, in Anglo-Saxon journals with high international visibility and impact in social media. Conclusions: Publications on COVID-19 in Pediatrics at SCOPUS show a continuous growth; however, it is consider as insufficient the number of articles on specific treatments for the pediatric population(AU)

Altmetrics: A new paradigm for scholarly communication

Counting citations have been the usual norm to determine the impact of any research and/or scholar. However, with majority of the scholarly activities happening on the World Wide Web, traditional counting of citations is now being termed “slower.” The recent explosion of online data storage for many articles may serve as a pool which uses social media sites to navigate. Altmetrics has been proposed as the new entity which aims to change the focus of the scholarly reward system to value and encourage web-native scholarship. This paper makes an attempt to understand altmetrics.

Objective To comparatively analyze the the relationship between PLoS ALMs,Altmetrics score and the indications for assessing the academic level of individual articles and their efficiency for assessing the academic level of individual articles. Methods The relationship of the viewed, downloaded, discussed, recommended counts and frequency of citation with Altmetrics score, h index, academic track T and their efficiency for assessing a single pa-per were comparatively analyzed with PLoS Biology and PLoS Medicine as an example. Results The viewed, down-loaded and discussed papers were positively related with the frequency of citation and h index, the recommended papers were not related with the h index and academic track T, and the Altmetrics score was moderately related with the red, downloaded and discussed papers, and was weakly related with the frequency of citation. Conclusion PLoS ALMS is a multidimensional assessment. Only it is measured with several indications, can it demonstrate a work’s comprehensive strength.

Analyzing the social impact of orthodontic articles published by Chinese authors in international journals during the past five years / 中华口腔医学杂志

Objective@#To evaluate and analyze the social impact of orthodontic articles published by Chinese authors in international journals during the past five years, using an altmetric tool; and to explore the practical value of altmetrics measures in the evaluation of dental research.@*Methods@#PubMed was searched via the Altmetric Explorer platform to identify orthodontic research articles that were published during 2012-2016, with at least one affiliation from China. Commentaries, news reports and editorials were excluded. By reading titles and abstracts, two authors carried out inclusion and exclusion of literature independently to exclude articles that are not related to orthodontics and retracted articles. Data extraction was performed simultaneously. Any disagreement was resolved by discussion. Linear regressions were used to analyze the association between Altmetric attention score (AAS) and potentially related factors.@*Results@#Among 864 articles identified from PubMed, a total of 206 received an AAS, and 160 articles were included for analyzing. The mean AAS of orthodontic research articles from China was 2.7 (95% confidence interval: 2.0 to 3.4). American Journal of Orthodontics and Dentofacial Orthopedics had the most scored articles (n=24) and the highest total AAS (67.0), while European Journal of Orthodontics had the highest mean AAS (3.8). All the top-3 articles were published in Cochrane Database of Systematic Reviews. Significant positive associations were found among high impact factors (P<0.05), high level of evidence (P<0.001) and the AAS.@*Conclusions@#Publishing more high-impact articles and high level of evidence articles improved the international social impact of orthodontic research from China. As a valuable supplement to citation counts, Altmetric measures had practical values in dental research area.
