Variables antropométricas en bipedestación en una población de trabajadores y trabajadoras en Latinoamérica: una búsqueda sistemática.
No full textAnthropometry plays a fundamental role in public health since it takes advantage of anthropometric data for the design of the workplace and personal protective equipment (PPE), which are key within the work environment; however, there are few studies on respect in Latin America. The methodology used was a systematic review of the standing anthropometric variables in a population of workers in Latin America, between May and October 2024. Of the results obtained, 3485 cases or related studies were reviewed. with anthropometry in the industrial environment and nine (9) were selected, who were those who met the inclusion and exclusion schemes, which gave an approximation or important contributions in this research in the prosecution of anthropometric studies that allow the design of jobs and improvement in terms of health and welfare of workers.La antropometría juega un papel fundamental en la salud pública puesto que se aprovecha de los datos antropométricos para el diseño del centro de trabajo y equipos de protección personal, que son claves dentro del medio ambiente de trabajo, sin embargo, existen pocos estudios al respecto en Latinoamérica. La metodología utilizada fue una revisión sistemática de las variables antropométricas en bipedestación en una población de trabajadores en Latinoamérica, entre mayo y octubre 2024. De los resultados obtenidos, se revisaron 3485 casos o estudios relacionados con antropometría en el medio industrial y se seleccionaron Nueve (9), que fueron los que cumplieron con los esquemas de inclusión y exclusión, destacando que dieron una aproximación o aportes importantes en esta investigación en la prosecución de estudios antropométricos, que permitan el diseño de los puestos de trabajo y la mejora en cuanto a la salud y bienestar de los trabajadores
Alcances de la Inteligencia Artificial (IA) y la Big Data en el Contexto Global.
No full textThe expansion of computer science and technological advances resulted in the birth of artificial intelligence based on BIG DATA and the processing of large amounts of data. Machines and technologies burst the paradigm shift of the last century, influencing knowledge and the industrial field. The present article, product of a research, aims to analyze what would be the scope of Artificial Intelligence (AI) and BIG DATA, allowing an improvement of living conditions in the global context. Methods, a documentary type research of secondary sources was carried out, level: descriptive research, taking what was investigated in the different documents to make a position on the researched topic Results: AI and BIG DATA are closely related being both interdependent, the scopes cover wide sectors of the world, such as: the industrial sector, health, finance, education and entertainment. Conclusions: AI should be used as a tool for human beings, but not to replace human intelligence, the scopes cover broad sectors in the global context, which should be monitored to allow equity, privacy and data protection in a framework of academic integrity.La expansión de la informática y los avances tecnológicos dieron como resultado el nacimiento de la inteligencia artificial tomando como apoyo la BIG DATA y el procesamiento de una gran cantidad de datos.

No full textGoing 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
Prediction of anthropometric variables in standing position in Venezuelan direct labor workers
No full textThe present research aims to predict anthropometric variables in workers of direct industrial labor force in bipedestation, with mathematical models or algorithms such as linear or multiple regression models, which facilitate the measurement process reducing costs and time in the research. The methodology was applied to a population sample of 185 workers (131M,54W) of Venezuelan industrial direct labor, located in the industrial zones of Aragua state, being its research level correlational-transversal-epidemiological. The research made use of the statistical procedure of linear and multiple regressions with the support of the mini tab-17 statistical package. From the statistical assumptions, the obtained functions of simple and multiple regression in the anthropometric variables in bipedestation, show us significant models (Average 95 %) for a P-value<0, 05 by age group and sex, which will allow to reduce the costs and time in the anthropometric measurements of the industrial direct labor workers in Venezuel
