Evaluación de las revistas científicas colombianas del área de Ciencias Médicas y de la Salud por medio del Índice de Osk / Evaluation of Colombian medical and health sciences journals using the Osk Index

Este estudio tuvo como objetivo la evaluación de las revistas científicas colombianas del área de Ciencias Médicas y de la Salud a través del sistema de medición integral de revistas científicas colombianas que se sustenta en el Índice de Osk. Se analizaron las 33 revistas científicas colombianas de Ciencias Médicas y de la Salud indexadas en el Índice Bibliográfico Nacional Publindex en la convocatoria 768 del año 2016, de las cuales solo se tuvieron en cuenta las ediciones y las citas comprendidas entre el periodo del 01 de enero al 31 de diciembre del año 2017. La revista que mayor valor presentó fue Biomédica, con un índice para el año 2017 de 314,30, seguida de la Revista Colombiana de Cardiología con 206,81, y en tercer lugar la Revista de Salud Pública con 201,15, las cuales se agrupan en el nivel O1. En el otro extremo y agrupándose de mayor a menor en el nivel O4 se encuentran la revista Duazary (41,78), la Revista Facultad de Odontología Universidad de Antioquia (38,19) y Vitae (35,12). A modo de conclusión, se hace preciso revisar el modelo actual de clasificación de las revistas en Colombia Publindex, teniendo en cuenta las particularidades encontradas durante la revisión. Es por eso que se recomienda la implementación de un modelo o sistema de medición integral, como es en este caso el Índice de Osk(AU)

The purpose of the study was to evaluate Colombian medical and health sciences journals using a comprehensive measurement system for Colombian scientific journals based on the Osk Index. An analysis was conducted of 33 Colombian medical and health sciences journals indexed in the National Bibliographic Index Publindex as of call for papers number 768 of 2016, from which only editions and citations from 1 January to 31 December 2017 were considered. The publication with the highest score was Biomédica, with an index of 314.30 for the year 2017, followed by Revista Colombiana de Cardiología with 206.81 and Revista de Salud Pública with 201.15, all three of them in level O1. On the opposite end, and grouped from highest to lowest in level O4 are the journals Duazary (41.78), Revista Facultad de Odontología Universidad de Antioquia (38.19) and Vitae (35.12). Conclusions point to the need to review the classification model currently applied to Colombian journals, Publindex, bearing in mind the particular features revealed by the study. It is therefore recommended to implement a comprehensive measurement model or system, as is the case with the Osk Index(AU)

Resumen La gerontología es comprendida como un enfoque interdisciplinario que aborda el proceso de envejecimiento y vejez. El presente artículo caracteriza la evolución de la investigación en el campo gerontológico durante los últimos 44 años a través de un análisis bibliométrico de los trabajos de mayor impacto en el área. Se revisaron 94 publicaciones de la colección principal de la Web of Science (WoS) de Thomson Reuters en el periodo 1975-2018. Se analizan las publicaciones y su evolución longitudinal, el acoplamiento de documentos clásicos, áreas de investigación, autores y co-autorías, revistas y países. Se concluye que Estados Unidos es el país que reúne la mayor cantidad de publicaciones, citas y revistas de difusión de textos clásicos.

Abstract Gerontology is understood as an interdisciplinary approach that addresses the process of aging and old age. The present article characterizes the evolution of research in the gerontological field during the last 44 years through a bibliometric analysis of the works of greatest impact in the area. Ninety-four publications were reviewed from the main collection of the Web of Science (WoS) by Thomson Reuters in the period 1975-2018. The publications and their longitudinal evolution, the coupling of classic documents, research areas, authors and co-authors, journals and countries are analyzed. It is concluded that the United States is the country with the largest number of publications, citations and journals disseminating classical texts.

One hundred citation classics in benign anorectal disease: a bibliometric analysis of seven decades (1950-2019) / Cem clássicos de citações em doença anorretal benigna: uma análise bibliométrica de sete décadas (1950-2019)

ABSTRACT Background & aim Bibliometric analysis is used to explore the historical development in a particular field. The aim is to identify and analyse most cited papers in benign anorectal disease in the last 7 decades (1950-2018). Method Thomson Reuters Web of Science database was used to find the top 100 cited articles in benign anorectal conditions. Papers were independently extracted by two investigators. The top 100 cited articles were identified and ranked according to number of citations. The articles were then sorted by author, journal, institution, country and publication date. The study subject was divided into 5 groups. Results The most frequently cited article received 1307 citations whereas the least cited received 154 citations. The earliest recorded article was published in 1960 and the most recent was from 2010. More than half of the articles addressed faecal incontinence and sphincter related literature (n = 54). The articles were published in 29 different journals. A majority (69%) of manuscripts originated from the USA (n = 35; 9221 citations) and UK (n = 34; 7796 citations). The origin of these top 100 classic papers was from 53 different institutions. St. Mark's Hospital in the UK had the highest number of articles (n = 21), followed by Cleveland clinic (n = 5) and University of Minnesota (n = 5). Conclusion The most highly cited manuscripts in benign anorectal disease cover a wide range of topics. Faecal incontinence and sphincter related articles had the highest number of citations. This review serves as a reference for researchers to find the influential papers in this field.

Evaluating Journal Impact Factor: a systematic survey of the pros and cons, and overview of alternative measures

Journal Impact Factor (JIF) has several intrinsic flaws, which highlight its inability to adequately measure citation distributions or indicate journal quality. Despite these flaws, JIF is still widely used within the academic community, resulting in the propagation of potentially misleading information. A critical review of the usefulness of JIF is needed including an overview of the literature to identify viable alternative metrics. The objectives of this study are: (1) to assess the usefulness of JIF by compiling and comparing its advantages and disadvantages; (2) to record the differential uses of JIF within research environments; and (3) to summarize and compare viable alternative measures to JIF. Methods: Three separate literature search strategies using MEDLINE and Web of Science were completed to address the three study objectives. Each search was completed in accordance with PRISMA guidelines. Results were compiled in tabular format and analyzed based on reporting frequency. Results: For objective (1), 84 studies were included in qualitative analysis. It was found that the recorded advantages of JIF were outweighed by disadvantages (18 disadvantages vs. 9 advantages). For objective (2), 653 records were included in a qualitative analysis. JIF was found to be most commonly used in journal ranking (n = 653, 100%) and calculation of scientific research productivity (n = 367, 56.2%). For objective (3), 65 works were included in qualitative analysis. These articles revealed 45 alternatives, which includes 18 alternatives that improve on highly reported disadvantages of JIF. Conclusion: JIF has many disadvantages and is applied beyond its original intent, leading to inaccurate information. Several metrics have been identified to improve on certain disadvantages of JIF. Integrated Impact Indicator (I3) shows great promise as an alternative to JIF. However, further scientometric analysis is needed to assess its properties.(AU)

Citación de fuentes documentales y escogencia de informantes: un estudio cualitativo de las razones expuestas por investigadores venezolanos / Citation of documentary sources and choice of informants: a qualitative study of the reasons given by venezuelan researchers

Resumen La presente investigación se propuso interpretar las razones que expone un grupo de investigadores para citar y descartar fuentes de información documentales y vivas. Para cumplir dicho propósito se realizó un estudio desde un enfoque cualitativo. Como técnicas se utilizaron la entrevista y el grupo focal de discusión. Los participantes en la investigación fueron doce investigadores activos, quienes aportaron la información en función de su experiencia y percepción subjetiva de la realidad. Los resultados se contrastaron con los criterios de fiabilidad y calidad de las fuentes de información expuestos en la literatura especializada. Entre los hallazgos más relevantes destaca la coincidencia en razones objetivas de selección y la diferencia entre las razones subjetivas de cada investigador. Por último, se presentan algunas recomendaciones para la selección de fuentes impresas y digitales, así como para la escogencia de fuentes vivas (informantes clave y expertos).

Abstract: The current investigation intends to interpret the reasons exposed by a group of researchers to cite and discard sources of live and documentary information. To achieve this goal, a study from a qualitative focus was carried out. Interviews and focal groups of discussion were used as techniques. The participants in the research were 12 active researchers, who provided the information based on their experience and subjective perception of reality. The results were contrasted with the reliability and quality criteria of the information sources exposed in the specialized literature. Among the most relevant findings, the coincidence in objective reasons of choice and the difference among the subjective reasons of each researcher stand out. Finally, some recommendations are presented for the selection of printed and digital sources, as well as for the choice of live sources (key informants and experts).

Researcher and Author Impact Metrics: Variety, Value, and Context

Numerous quantitative indicators are currently available for evaluating research productivity. No single metric is suitable for comprehensive evaluation of the author-level impact. The choice of particular metrics depends on the purpose and context of the evaluation. The aim of this article is to overview some of the widely employed author impact metrics and highlight perspectives of their optimal use. The h-index is one of the most popular metrics for research evaluation, which is easy to calculate and understandable for non-experts. It is automatically displayed on researcher and author profiles on citation databases such as Scopus and Web of Science. Its main advantage relates to the combined approach to the quantification of publication and citation counts. This index is increasingly cited globally. Being an appropriate indicator of publication and citation activity of highly productive and successfully promoted authors, the h-index has been criticized primarily for disadvantaging early career researchers and authors with a few indexed publications. Numerous variants of the index have been proposed to overcome its limitations. Alternative metrics have also emerged to highlight ‘societal impact.’ However, each of these traditional and alternative metrics has its own drawbacks, necessitating careful analyses of the context of social attention and value of publication and citation sets. Perspectives of the optimal use of researcher and author metrics is dependent on evaluation purposes and compounded by information sourced from various global, national, and specialist bibliographic databases.

Latin American scientific contribution to ecology

ABSTRACT Latin America embodies countries of special interest for ecological studies, given that areas with great value for biodiversity are located within their territories. This highlights the importance of an evaluation of ecological research in the Latin America region. We assessed the scientific participation of Latin American researchers in ecological journals, patterns of international collaboration, and defined the main characteristics of the articles. Although Latin American publications have increased in fourteen years, they accounted up to 9% of publications in Ecology. Brazil leaded the scientific production in Latin America, followed by Argentina and Mexico. In general, Latin American articles represented a low percentage of most journals total publication, with particularly low expression in high impact-factor journals. A half of the Latin American publications had international collaboration. Articles with more than five authors and with international collaboration were the most cited. Descriptive studies, mainly based in old theories, are still majority, suggesting that Ecology is in a developing stage in Latin America.

Bibliometry of the Revista de Biología Tropical / International Journal of Tropical Biology and Conservation: document types, languages, countries, institutions, citations and article lifespan / Bibliometría de la Revista de Biología Tropical: tipos de documento, idiomas, países, instituciones, citas y longevidad de los artículos

Abstract:The Revista de Biología Tropical / International Journal of Tropical Biology and Conservation, founded in 1953, publishes feature articles about tropical nature and is considered one of the leading journals in Latin America. This article analyzes document type, language, countries, institutions, citations and -for the first time- article lifespan, from 1976 through 2014. We analyzed 3 978 documents from the Science Citation Index Expanded. Articles comprised 88 % of the total production and had 3.7 citations on average, lower than reviews. Spanish and English articles were nearly equal in numbers, and citation for English articles was only slightly higher. Costa Rica, Mexico, and the USA are the countries with more articles, and the leading institutions were Universidad de Costa Rica, Universidad Nacional, Universidad Nacional Autónoma de Mexico and Universidad de Oriente (Venezuela). The citation lifespan of articles is long, around 37 years. It is not surprising that Costa Rica, Mexico, and Venezuela lead in productivity and cooperation, because they are mostly covered by tropical ecosystems and share a common culture and a tradition of scientific cooperation. The same applies to the leading institutions, which are among the largest Spanish language universities in the neotropical region. American output can be explained by the regional presence of the Smithsonian Tropical Research Institute and the Organization for Tropical Studies. Tropical research does not have the rapid change typical of medical research, and for this reason, the impact factor misses most of citations for the Revista, which are made after the two-year window used by the Web of Science. This issue is especially damaging for the Revista because most journals that deal with tropical biology are never checked when citations are counted by the Science Citation Index. Rev. Biol. Trop. 64 (3): 1223-1235. Epub 2016 September 01.

ResumenLa Revista de Biología Tropical/International Journal of Tropical Biology and Conservation, fundada en 1953, publica artículos de fondo sobre la naturaleza tropical y es considerada una de las revistas líderes en América Latina. Este artículo considera tipos de documentos, idioma, países, instituciones, citas y, por primera vez, longevidad de artículos. Analizamos 3 978 documentos entre 1976 y 2014, del Science Citation Index Expanded (base de datos de la Web of Science). Los artículos representan 88 % de la producción total y reciben en promedio 3.7 citas (las revisiones reciben más). Los artículos en español e inglés son casi iguales en número y citas recibidas (ligeramente más en los artículos en inglés). Costa Rica, México y EE.UU. son los países con más artículos y las principales instituciones son: Universidad de Costa Rica, Universidad Nacional (Heredia), Universidad Nacional Autónoma de México y Universidad de Oriente (Venezuela). Los artículos siguen siendo citados, en promedio, durante 37 años. No es de extrañar que Costa Rica, México y Venezuela dominen la productividad y la cooperación, porque están cubiertos en su mayoría por ecosistemas tropicales, comparten una cultura y tienen una tradición de cooperación científica. Lo mismo ocurre con las instituciones líderes, que están entre las mayores universidades de lengua española en la región neotropical. La alta producción estadounidense se explica por la presencia regional del Instituto Smithsoniano de Investigaciones Tropicales y la Organización para Estudios Tropicales. La investigación tropical no tiene el rápido avance típico de la investigación médica, por lo que el factor de impacto falla al dejar por fuera la mayor parte de las citas que recibe la Revista, las cuales se producen después de los dos años que cubre Web of Science. Esto es particularmente desventajoso, porque Science Citation Index Expanded, al contar las citas, no revisa la mayoría de las revistas que se ocupan de la biología tropical.

Estilos de citas y referencias bibliográficas en revistas odontológicas SciELO: un elemento crítico de la escritura científica / Styles for citations and referencing in dental SciELO journals: a critical element of scientific writing

Uno de los problemas más comunes en las revistas científicas, es el incumplimiento de los estilos al hacer citas y escribir las referencias bibliográficas, debido al descuido o bien al desconocimiento de los diferentes sistemas existentes y sus características. El objetivo fue revisar los estilos de citas y referencias utilizados por revistas odontológicas indexadas en la red SciELO, con el fin describir los más utilizados y evidenciar las diferencias existentes entre las revistas. Fueron revisados 100 artículos pertenecientes a 20 revistas diferentes, seleccionados aleatoriamente por afijación proporcional. El estilo más utilizado para las citas y referencias bibliográficas correspondió al sistema Vancouver. Sólo una revista, International Journal of Odontostomatology publica sus artículos bajo el sistema Harvard. Estos estilos sirven como un sello de las revistas, pero constituyen una carga de trabajo adicional significativa, ya que la atención a los detalles que se requieren para asegurar que las citas y referencias se ajusten a los estilos individuales de las revistas es fundamental. Cualquiera sea el estilo de la revista, es importante utilizarlo de una manera consistente. La responsabilidad de la exactitud en las citas y referencias bibliográficas es de los autores, por lo que deben preocuparse de ello al redactar el artículo, en su revisión final previo al envío, así como en las pruebas de imprenta.

One of the most common problems in scientific journals, it is the failure of the styles to make citations and references due to carelessness or ignorance of the different systems and their characteristics. The aim was to review the different styles of citations and references used by dental journals indexed in SciELO, to describe the most used and highlight the differences between journals. One hundred articles randomly selected by proportional allocation, belonging to 20 different journals were reviewed. The most commonly used format for citations and references corresponded to the Vancouver system. Only a journal, International Journal of Odontostomatology publishes his articles under the Harvard system. These styles serve as a hallmark for journals, but they are a significant additional workload as the attention to detail required to ensure that citations and references fit individual styles of the journals is fundamental. Whatever the style of the journals, it is important to use it in a consistent manner. The responsibility for the accuracy in citations and references belongs to the authors, so they should worry about it in drafting version, its final revision, as well as proofs of the article.

Finlay HMC. 14.1 percent of the contributions with citations (21) were published with institutional collaboration, from 14.1 percent of the total number of female authors. There were 7 main authors who predominated out of 9. Conclusions: The articles by male researchers of Dr. Luis Díaz Soto and Dr. Carlos J. Finlay central military hospitals were identified as success factors for the 149 original articles published in the RCMM, out of a total of 90 authors who ranked RCMM(AU)

The h-Index in academic morphology / El Índice h en la morfología académica

The h-index is an objective and easily calculable measure that can be used to evaluate both the relevance and amount of scientific contributions of an individual author and field. The aim was to examine how the h-index of academic morphologists in Chile relates with academic rank. A descriptive and correlational study was design. We accessed the Chilean Society of Anatomy professor list in January of 2015, for analysis of academic morphologists' h-indexes using the Scopus database, and data was organized by academic rank. Also, m-Quotient was calculated. Institutional productivity was measured, and institutions were ranked on the basis of cumulative h-index, m-Quotient and the total number of publications and citations. For all morphologists analyzed, the mean h-index was 2.9±2.94 (range 0­12). The mean h-indexes were 1.9±2.135 for instructors, 2.5±2.54 for assistant, 5.1±2.89 for associate and 4.7±3.92 for professors. There was a significant relationship between h-index and academic rank (P<0.001). The m-Quotient were significantly different between assistant/associate and professors (P<0.001). By academic degree, the mean h-indexes were 1.0±1.92 for Bachelor, 1.6±2.0 for specialists, 2.3±2.26 for masters and 4.9±3.4 for Ph.D. The total number of publications for Chilean morphologist was 1343 publications (13.85±18.392), with 5321 citations (54.86±106.392). The top 3 institutions were Universidad de La Frontera, Universidad de Chile and Pontificia Universidad Católica de Chile. Multivariate logistic regression analysis demonstrated that h-index (P<0.001) and number of publications (P<0.001) were the best predictors of academic rank. There exists a significant relationship between h-index and academic rank, with h-index increasing with academic rank. It is a reliable tool for quantifying academic productivity within morphology, easily calculable and may be useful when evaluating decisions regarding advancement within academic morphology departments. These results should serve as benchmarks for future studies.

El índice h es una medida objetiva y fácilmente calculable que se puede utilizar para evaluar la importancia y cantidad de contribuciones científicas de un autor y área del conocimiento. El objetivo fue evaluar el índice h de morfólogos académicos en Chile, y su relación con la jerarquía académica. Se diseño un estudio descriptivo correlacional. Se accedido a la lista de profesores de la Sociedad Chilena de Anatomía en enero del 2015; para el análisis del índice h de los académicos morfólogos se utilizó la base de datos Scopus, y los datos fueron organizados por jerarquía académica. Además, se calculó cociente m. Se midió la productividad institucional clasificándose sobre la base de índice h y cociente m acumulados, y el número total de publicaciones y citaciones. Para todos morfólogos analizados, la Media del índice h fue de 2,9±2,94 (rango 0­12). Según jerarquía académica, se observaron índices h de 1,9±2,135 para instructores, 2,5±2,54 para asistentes, 5,1±2,89 para asociados y 4,7±3,92 para profesores titulares. Hubo una relación significativa entre el índice h y jerarquía (P<0,001). Los Cocientes m fueron significativamente diferentes entre los profesores asistente/asociado (mayor) y titulares (P<0,001). Según el grado académico, la Media de los índices h fueron 1,0±1,92 para licenciados, 1,6±2,0 para especialistas, 2,3±2,26 para magíster y 4,9±3,4 para los Ph.D. El número total de publicaciones para los morfólogos chilenos fue 1.343 (13,85±18,392), con 5.321 citas (54,86±106.392). Las 3 mejores instituciones fueron Universidad de La Frontera, Universidad de Chile y Pontificia Universidad Católica de Chile. El análisis de regresión logística multivariante demostró que el índice h (P<0,001) y el número de publicaciones (P<0,001) fueron los mejores predictores de jerarquía académica. Existe una relación significativa entre el índice h y jerarquía, al aumentar el índice h aumenta la jerarquía. El índice h es una herramienta fiable para cuantificar la productividad académica dentro de la morfología, fácilmente calculable y puede ser útil en la evaluación de las decisiones relativas a la promoción dentro de los departamentos académicos en el área morfológica. Estos resultados deben servir como puntos de referencia para futuros estudios.

Preserving the Integrity of Citations and References by All Stakeholders of Science Communication

Citations to scholarly items are building bricks for multidisciplinary science communication. Citation analyses are currently influencing individual career advancement and ranking of academic and research institutions worldwide. This article overviews the involvement of scientific authors, reviewers, editors, publishers, indexers, and learned associations in the citing and referencing to preserve the integrity of science communication. Authors are responsible for thorough bibliographic searches to select relevant references for their articles, comprehend main points, and cite them in an ethical way. Reviewers and editors may perform additional searches and recommend missing essential references. Publishers, in turn, are in a position to instruct their authors over the citations and references, provide tools for validation of references, and open access to bibliographies. Publicly available reference lists bear important information about the novelty and relatedness of the scholarly items with the published literature. Few editorial associations have dealt with the issue of citations and properly managed references. As a prime example, the International Committee of Medical Journal Editors (ICMJE) issued in December 2014 an updated set of recommendations on the need for citing primary literature and avoiding unethical references, which are applicable to the global scientific community. With the exponential growth of literature and related references, it is critically important to define functions of all stakeholders of science communication in curbing the issue of irrational and unethical citations and thereby improve the quality and indexability of scholarly journals.

Reference Accuracy: Authors', Reviewers', Editors', and Publishers' Contributions

Scientific authors are responsible for the accuracy of their writings and references to others' works. However, relying on authors is not enough when it comes to processing their manuscripts. Joint efforts of authors, peer reviewers, editors, and publishers throughout the publishing process may prevent most reference errors. This article analyzes essential aspects of bibliographic management and focuses on the importance of validating references by all stakeholders of scholarly publishing.

Científicos cubanos de la biomedicina más productivos en el período 1996-2011 según Medline / Cuban most productive biomedicine scientists in Medline in the period 1996-2011

Cuba es un país caracterizado por poseer un gran número de investigadores y profesores, pero no por la cantidad de artículos científicos que publica. El objetivo de este trabajo es caracterizar la producción científica de las ciencias médicas cubanas a partir de la obra de sus autores más productivos y evaluar su experiencia como autor. Se utiliza el asistente de búsqueda GoPubMed y, a partir de la palabra Cuba, se toman los 20 autores cubanos más productivos a los que se les caracteriza su productividad en las bases PubMed y Scopus, además de su índice H. Paralelamente se realiza una encuesta a cada autor por correo electrónico. Entre las variables recogidas más importantes están el tiempo transcurrido desde la graduación hasta la salida del primer artículo, idiomas que prefiere publicar y conocimientos y uso adecuado de herramientas bibliométricas de estos autores. Hay una correspondencia entre el total de los trabajos referidos por cada autor y el total de trabajos recuperados por Scopus. Las correlaciones estadísticamente significativas fueron el número de años transcurridos desde la graduación hasta la fecha de publicación del primer artículo con el total de trabajos referidos por el autor y el total de trabajos recuperados en la base Scopus. Existe correlación significativa entre PubMed y GoPubMed; sin embargo, no resulta significativa entre PubMed y Scopus. A mayor número de trabajos recuperados por Scopus hay un incremento en el número de citas reflejadas en esta base. Los autores más productivos no aprovechan las posibilidades que brinda el conocimiento de los que lo citan y el índice H para trazar estrategias para su desarrollo científico; prefieren escribir en idioma inglés y no tienen uniformidad en la forma en que firman sus trabajos.

Cuba is a country with a large number of researchers and academics but without great quantity of published papers.The aim of this paper is to characterize the scientific production in the Cuban medical sciences throughout the most productive authors and to evaluate their experience in this topic. GoPubMed data base was employed using Cuba as filter Word. The productivity of the twenty most productive Cuban authors in PubMed, GoPubMed and Scopus databases was determined including H index. A questionnaire was sent to each author by email. Among the most important collected variables are the time between their graduation and the appearance of their first paper, favourite publishing language, and knowledges and use of bibiiometric tools. There is a relationship between the total paper published by the author and the number of paper recovered by Scopus. A statistically significant correlation was produced between PubMed and GoPubMed but Scopus. More quantity of recovered papers from Scopus database produced more citations in such database. The most productive authors do not take advantage on the knowledge that the citation offers to make scientific developmental strategies. They prefer to publish in English language and they don't have a unique way to sign their papers.

Articles with short titles describing the results are cited more often

OBJECTIVE: The aim of this study was to evaluate some features of article titles from open access journals and to assess the possible impact of these titles on predicting the number of article views and citations. METHODS: Research articles (n = 423, published in October 2008) from all Public Library of Science (PLoS) journals and from 12 Biomed Central (BMC) journals were evaluated. Publication metrics (views and citations) were analyzed in December 2011. The titles were classified according to their contents, namely methods-describing titles and results-describing titles. The number of title characters, title typology, the use of a question mark, reference to a specific geographical region, and the use of a colon or a hyphen separating different ideas within a sentence were analyzed to identify predictors of views and citations. A logistic regression model was used to identify independent title characteristics that could predict citation rates. RESULTS: Short-titled articles had higher viewing and citation rates than those with longer titles. Titles containing a question mark, containing a reference to a specific geographical region, and that used a colon or a hyphen were associated with a lower number of citations. Articles with results-describing titles were cited more often than those with methods-describing titles. After multivariate analysis, only a low number of characters and title typology remained as predictors of the number of citations. CONCLUSIONS: Some features of article titles can help predict the number of article views and citation counts. Short titles presenting results or conclusions were independently associated with higher citation counts. The findings presented here could be used by authors, reviewers, and editors to maximize the impact of articles in the scientific community.

Índice-H dos artigos citantes: uma contribuição para a avaliação da produção científica de pesquisadores experientes / H-index of the citing articles: a contribution to the evaluation of scientific production of experienced researchers

INTRODUÇÃO: Há um crescente interesse e necessidade em avaliar a qualidade da produção científica dos pesquisadores. Para tal, as métricas mais importantes são: número de citações, número médio de citações por artigo indexado e o índice-H. Contudo, essas métricas apresentam limitações na avaliação do potencial de impacto das publicações de um pesquisador, especialmente dentre aqueles mais produtivos. OBJETIVO: Propor e demonstrar a utilização de uma nova métrica científica - índice-H dos artigos citantes, que permite refinar a discriminação do impacto das publicações de pesquisadores experientes sobre o conhecimento existente em sua área. MÉTODOS: Foram analisados dados da Web of Science de 13 dentre os pesquisadores doutores brasileiros mais produtivos na área de exercício físico e esporte, incluindo: número de artigos publicados, número de citações, número médio de citações por artigos, índice-H e o índice-H dos artigos citantes, ou seja, o índice-H obtido a partir da ordenação decrescente dos artigos que citaram artigos publicados pelo pesquisador. Dados de quatro outros pesquisadores - brasileiros e estrangeiros - foram usados como marcos de referência para comparações. RESULTADOS: Os índice-H do pesquisador e o dos artigos citantes são associados (r = 0,92; p > 0,01), porém, quando são analisados os seis pesquisadores mais produtivos, com índices-H acima de 7, a associação entre os dois índices-H desaparece (r = 0,35; p = 0,49). CONCLUSÃO: O índice-H dos artigos citantes pode contribuir para diferenciar a produção científica de pesquisadores com um grande número de artigos publicados. Sugere-se a adoção de sua mensuração pelas agências brasileiras e estrangeiras de fomento e de avaliação da produção científica.

BACKGROUND: there has been an increasing interest and need in evaluating the quality of scientific papers written by researchers. Therefore, the most important measurements used are the number of citations, the average number of citations per article published in indexed journals and the H-index. Those bibliometric indicators present, however, limitations when assessing the potential impact of the publications of a given researcher, particularly among the most productive ones. OBJECTIVE: To propose and to demonstrate the use of a new scienciometric strategy - the H-index of the citing articles-, that allow to better discriminate the impact of a given researcher to the body of knowledge in the respective research area. METHODS: Research data - Web of Science - from 13 of the most productive Brazilian PhD researchers in the field of exercise and sport sciences were analyzed, including: number of publications, number of citations, average number of citations per article, H-index and the proposed H-index of citing articles (the H-index extracted from the ranking of articles that cited the papers published by a given researcher). Data from four other researchers - Brazilian and foreign - were used as reference for comparisons. RESULTS: The researcher's H-index and the H-index of the citing articles were associated (r=.92; p>.01). However, when the six most productive authors were analyzed with H-index above 7, the association between the two indexes disappears (r=.35; p=.49). CONCLUSIONS: The H-index of the citing articles can be useful to discriminate the scientific production of authors with a high number of published papers. It is suggested that this algorithm should be adopted by Brazilian and foreign financing and scientific production evaluation agencies.

Citations to papers from Brazilian institutions: a more effective indicator to assess productivity and the impact of research in graduate programs

A recent assessment of 4400 postgraduate courses in Brazil by CAPES (a federal government agency dedicated to the improvement of the quality of and research at the postgraduate level) stimulated a large amount of manifestations in the press, scientific journals and scientific congresses. This gigantic effort to classify 16,400 scientific journals in order to provide indicators for assessment proved to be puzzling and methodologically erroneous in terms of gauging the institutions from a metric point of view. A simple algorithm is proposed here to weigh the scientometric indicators that should be considered in the assessment of a scientific institution. I conclude here that the simple gauge of the total number of citations accounts for both the productivity of scientists and the impact of articles. The effort spent in this exercise is relatively small, and the sources of information are fully accessible. As an exercise to estimate the value of the methodology, 12 institutions of physics (10 from Brazil, one from the USA and one from Italy) have been evaluated.
