Área de Ciencias, PerúEste artículo analiza la producción científica sobre ALFIN (2001-2020) en las áreas de Bibliotecología y Ciencias de la Información. A partir de Latindex, se identificaron todas las revistas de ByCI. Luego se verificó, si dichas revistas, estaban contenidas en las siguientes bases de datos: Web of Science (Core Collection y Scielo Citation Index), Scopus, Lens y Dimensions. Para la recuperación de registros sobre ALFIN y realizar el análisis bibliométrico, se eligió la base de datos Lens, por tener la mayor cobertura de revistas de ByCI en Latindex. Se evaluaron la tendencia y el crecimiento de la producción científica según autores y año de publicación; se analizó la productividad de los autores mediante la Ley de Lotka y la dispersión de la literatura según la Ley de Bradford. Se determinó el grado, índice y coeficiente de colaboración y se identificaron las redes de colaboración según autores. Los resultados muestran que la producción científica sobre ALFIN en Latinoamérica, alcanzó un pico entre los años 2017 y 2018, presentando un decrecimiento a partir del año 2019. Asimismo, se observó que la producción, colaboración entre autores y la cantidad de revistas es predominantemente brasileña.This article analyzes the scientific production on ALFIN (2001-2020) in the areas of Library and Information Science. All BIC journals were identified from Latindex. Then it was verified whether these journals were contained in the following databases: Web of Science (Core Collection and Scielo Citation Index), Scopus, Lens and Dimensions. The Lens database was chosen for retrieving records on ALFIN and performing the bibliometric analysis, as it has the highest coverage of BIC journals in Latindex. The trend and growth of scientific production were evaluated according to authors and year of publication; the productivity of authors was analyzed using Lotka’s Law and the dispersion of the literature according to Bradford’s Law. The degree, index, and coefficient of collaboration were determined and collaboration networks were identified according to authors. The results show that scientific production on ALFIN in Latin America, reached a peak between 2017 and 2018, presenting a decrease from 2019 onwards. It was also observed that the production, collaboration among authors, and the quantity of journals is predominantly Brazilian

¿Eres autor de un artículo científico? ¡Combate los vicios de autoría!
Full text linkThe benefits of scientific collaboration through co-authorship are widely recognized, which has driven a growing trend in the number of authors per document. However, the increase in collaboration has been accompanied by a set of research misconduct, where individuals included as authors in a publication do not actually meet the required criteria for authorship. This article details the criteria that every person must meet to be considered an author of a publication according to the International Committee of Medical Journal Editors. It is the responsibility of the authors, and not the editors of the journal to which the document is submitted, to determine and verify that all persons named as authors meet the four criteria. Finally, the question of whether technology assisted by artificial intelligence (AI) can be considered the author is addressed
Cuartiles : una mirada a los indicadores bibliométricos para revistas científicas
No full textEvento organizado por la Dirección de Gestión del Conocimiento - Biblioteca, realizado el día 02/Nov/22.
Participaron: Cesar H. Limaymanta (Perú) - Ponente;
Moderaron: Alonso Suarez Espinoza (Perú).
Universidad Peruana de Ciencias Aplicadas. Lima, Perú.El Sistema de Bibliotecas de la UPC organiza la videoconferencia titulada "Cuartiles : una mirada a los indicadores bibliométricos para revistas científicas", que está a cargo del expositor Dr. Cesar H. Limaymanta, investigador Renacyt y docente de Bibliometría, Estadística e Investigación (UNMSM, UPC).
En este evento se expondrán los principales indicadores bibliométricos que se utilizan para clasificar revistas según cuartiles. Esto porque existe confusión sobre cuáles son los más relevantes para las instituciones evaluadoras; debido a la variedad existente. El ponente compartirá las particularidades de cada indicador (SJR, Factor de impacto, CiteScore y Journal Citation Indicator) para clasificar revistas científicas en cuartiles. El evento culmina con el análisis de algunas declaraciones sobre el uso responsable de las métricas para la evaluación
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
