ABSTRACT

Se han propuesto varios indicadores bibliométricos para evaluar el desempeño de los investigadores a nivel mundial, uno de ellos es el índice h que considera tanto el número de publicaciones como las citas recibidas, y posiciona a los investigadores según una escala propuesta por Jorge Hirsch en investigador exitoso (h=20), excelentes científicos (h=40) y como un individuo singular (h=60). El objetivo del estudio fue evaluar el desempeño de investigadores paraguayos de las disciplinas de medicina, bioquímica y biología a través del Índice h de Hirsch comparando Google Scholar y Scopus. Es un estudio descriptivo con enfoque cuantitativo. Se incluyeron todos los investigadores paraguayos de las áreas mencionadas cuyos datos se encontraban disponibles en Google Scholar y/o Scopus. Para la identificación inicial de los investigadores se recurrió al cvpy disponible en la página web del CONACYT, Paraguay, y se utilizó el software Publish or Perish. Se identificaron 158 investigadores, de ellos ocho están posicionados en la escala de Hirsch. El 13 % de los investigadores tuvieron un índice h igual o mayor a 10 en Google Scholar y Scopus, correspondiendo al área de medicina el valor más alto, 54 en Google Scholar y 47 en Scopus. El desempeño de los investigadores por el índice h está por debajo de la región. Existe necesidad de mayor inversión en las revistas científicas nacionales para su indexación en bases de datos que colecciona revistas de mayor impacto.


Several bibliometric indicators have been proposed to evaluate the performance of researchers worldwide, one of them is the h index that takes into account both the number of publications and citations, and ranks researchers according to a scale proposed by Jorge Hirsch in successful researcher (h=20), excellent scientists (h=40) and as a singular individual (h=60). The objective of the study was to evaluate the performance of Paraguayan researchers from the disciplines of medicine, biochemistry and biology through the Hirsch h-Index comparing Google Scholar and Scopus. All Paraguayan researchers from the aforementioned areas whose data were available in Google Scholar and/or Scopus were included. It is a descriptive study with a quantitative approach. For the initial identification of the researchers, the cvpy available on the CONACYT, Paraguay website was used, and the Publish or Perish software was used. 158 researchers were identified, eight of them are positioned on the Hirsch scale. 13% of researchers had an h index equal to or greater than 10 in Google Scholar and Scopus, with the highest value corresponding to the area of ​​medicine, 54 in Google Scholar and 47 in Scopus. Researchers mostly publish in low-impact national journals with few citations. The performance of the researchers by the h-index is below the region. There is a need for greater investment in national scientific journals for their indexing in databases that collect journals with higher impact.

ABSTRACT

@#This paper aims to explore the feasibility of establishing a representative work screening method based on the academic recognition of the paper. Through comparative analysis of the strong and weak points of representative method, h-index core method, the subjective selection results by faculty applying for higher professional titles, and the academic recognition method established in this research (Q1 Journal-Percentile in Subject Area-Category Normalized Citation Impact, Q1-PSA-CNCI), representative works were introduced into the Z-index to form the Zh, Zr and Zq-index, and the correlations between the indicators were analyzed. Compared with other methods, the number of representative works obtained by the Q1-PSA-CNCI method is more reasonable. There was significant correlation among the indicators (P < 0.05), with no significant difference in the Zq-index among faculty evaluated for different professional titles (P > 0.05). Studies have shown that the Q1-PSA-CNCI method could help to screen representative works and was more reasonable than the number of representative works selected based on the other two methods, so Zq-index could be used as an indicator for representative work evaluation to provide reference for the qualitative evaluation of papers. It is more reasonable to improve the review process with the participation of "small peers".

ABSTRACT

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.

ABSTRACT

The h-index is frequently used to measure the performance of single scientists in Korea (and beyond). No single indicator alone, however, is able to provide a stable and complete assessment of performance. The Stata command bibrep.ado is introduced which automatically produces bibliometric reports for single researchers (senior researchers working in the natural or life sciences). The user of the command receives a comprehensive bibliometric report which can be used in research evaluation instead of the h-index.

ABSTRACT

OBJECTIVES: The purpose of this study is to analyze the co-author networks in the Journal of the Korean Academy of Child and Adolescent Psychiatry, a representative journal published by a branch of the domestic psychiatric academy, in order to present the current state of the co-authoring of and developments in child and adolescent psychiatry. METHODS: We visualized and estimated the basic characteristics of the co-author networks shown by 564 authors who wrote 251 papers published in the Journal of the Korean Academy of Child and Adolescent Psychiatry between 2005 and 2015, in order to assess their network characteristics, author centrality, and relevance to research performance. RESULTS: The co-author networks in the Journal of the Korean Academy of Child and Adolescent Psychiatry showed the characteristics of a small world and scale-free network. There was a correlation between the author centrality within the network and the research performance of the authors, but less correlation was shown between the centrality and mean paper citation counts. CONCLUSION: The network structure in the Journal of the Korean Academy of Child and Adolescent Psychiatry showed similarity to the co-authoring of other branches. However, given that the mean paper citation counts were less correlated with the author centrality than those in other branches, it may be necessary to promote an increase in the mean paper citation counts.

ABSTRACT

Traditionally, the success of a researcher is assessed by the number of publications he or she publishes in peer-reviewed, indexed, high impact journals. This essential yardstick, often referred to as the impact of a specific researcher, is assessed through the use of various metrics. While researchers may be acquainted with such matrices, many do not know how to use them to enhance their careers. In addition to these metrics, a number of other factors should be taken into consideration to objectively evaluate a scientist′s profile as a researcher and academician. Moreover, each metric has its own limitations that need to be considered when selecting an appropriate metric for evaluation. This paper provides a broad overview of the wide array of metrics currently in use in academia and research. Popular metrics are discussed and defined, including traditional metrics and article-level metrics, some of which are applied to researchers for a greater understanding of a particular concept, including varicocele that is the thematic area of this Special Issue of Asian Journal of Andrology. We recommend the combined use of quantitative and qualitative evaluation using judiciously selected metrics for a more objective assessment of scholarly output and research impact.

ABSTRACT

Hemolysis frequently causes preanalytical errors in laboratory measurements. We aimed to develop a quality improvement indicator for evaluating the extent of inappropriate procedures causing hemolysis in clinical samples collected in medical care units. We defined the threshold value of the hemolysis index (H index) causing significant interference with analyte measurement and analyzed the H index values of clinical samples in relation to the threshold. The H index threshold value causing a 10% bias in the measurement of lactate dehydrogenase was found to be 25. The monthly mean H index and monthly frequency of samples with an H index >25 were significantly different among the types of ward (P=0.001, respectively), and significantly decreased after replacement of a laboratory centrifuge lacking temperature control (20.6±0.58 vs 23.30±1.08, P=0.01; 23.4±1.69% vs 32.6±1.78%, P=0.01). The monthly mean H index and the monthly frequency of samples with an H index above a threshold value may be useful quality improvement indicators for detection of inappropriate procedures in the acquisition and handling of blood samples in medical care units.

ABSTRACT

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.

ABSTRACT

Objective To assess the academic influence of research on blood pressure in the world and its frontiers. Methods Papers on blood pressure published from 2004 to 2008 and from 2009 to 2013 in China and foreign coun-tries were retrieved from Web of Science. Their academic influencing power was assessed and their evolution in the past 10 years was displayed by Citespace. Results The world outputs in research on blood pressure increased steadily from 2004 to 2014. The competitive force of the USA-led developed Western countries was strong and stable. The out-puts in research on blood pressure in China increased rapidly, but its influencing power was relatively low. Although progress was made at micro and macro levels,greater advances were achieved at gene,molecular and big data levels in the past 10 years. Conclusion The USA and European countries-led development in research on blood pressure is steady, and it is urgent for China to reduce its gap with USA and European countries.

ABSTRACT

Objective: To conduct a critical analysis of the two main bibliometric indexes used by science: the impact factor and the H index. Method: Research was conducted on PubMed using the keywords: impact factor, Bibliometrics and H index. Results: The citations of articles tend to follow a curve in which the articles published in a given year increase sharply to a peak occurring between two and six years after its publication. From this peak citations decline over time. Conclusion: The analysis of the scientific merit should not be based on only in bibliometric measure, but in the association of various parameters. The impact factor and the H index is mainly based on the number of citations of scientific papers, and this parameter, although important, should not be used alone, nor overvalued in the evaluation of teaching merit.


Objetivo: Realizar análise crítica dos dois principais índices bibliométricos utilizados pela ciência: o fator de impacto e o índice H. Método: Foi realizada pesquisa no Pubmed utilizando as palavras-chave: impact factor, bibliometrics, H index. Resultados: As citações dos artigos tendem a seguir uma curva em que os artigos publicados em determinado ano aumentam agudamente para um pico que ocorre entre dois e seis anos após sua publicação. A partir deste pico, as citações declinam ao longo do tempo. Conclusão: A análise do mérito científico não deve ser baseada em apenas uma medida bibliométrica, mas em associação de medidas. O FI e o índice H se baseiam fundamentalmente no número de citações dos artigos científicos, e este parâmetro, apesar de importante, não deve ser utilizado sozinho e tampouco supervalorizado na avaliação do mérito docente.

ABSTRACT

Objective To assess the academic influence of schistosomiasis control and research institutions in China. Meth-ods The papers (including original articles and reviews) pertaining to schistosomiasis in Science Citation Index Expanded (SCIE)of Web of Science(WOS)during the period from 2002 to 2012 were searched. The number of published papers,h index and citation frequencies of the papers of Chinese institutes and authors were analyzed by a bibliometric method,and the academic influences of the institutes and authors were assessed according to the number of published papers and h index. In addition,the scientific knowledge network map was plotted by using the CiteSpace II software to analyze the inter-institution academic collabora-tion network. Results From 2002 to 2012,totally 610 papers pertaining to schistosomiasis were published by Chinese scholars, accounted for 16.7%of the published papers in global,and the quantity increased year by year. The number of published papers and h index of the National Institute of Parasitic Diseases(NIPD),China Center for Disease Control and Prevention(China CDC) were 114 and 27,respectively,both of which were ranked at the first position among all the Chinese institutes,and in the academ-ic collaboration network,the NIPD played a central and dominate part. Xiao-Nong Zhou with the h index of 17 became the out-standing academic leader in the research field of schistosomiasis control. Conclusions Both number of published papers in SCIE and h index of the Chinese institutes for schistosomiasis control are far inferior to the leading institutions in the world. It suggests that when strengthening the research and control of schistosomiasis,we should pay an attention to the output and sharing of the control experience and achievements.
