Propuesta de diseño del sistema de gestión de fatiga por riesgo psicosocial para los trabajadores en modalidad de trabajo por turnos en la planta de Esenttia
No full textLa fatiga que se da como resultado del trabajo en turnos impacta la respuesta cognitiva y física ante situaciones de demanda, resultando en mayores tiempos de respuesta, así como la reducción de la conciencia situacional, con el consecuente aumento del riesgo de ocurrencia de errores operativos y accidentes laborales.
De otra parte, una inadecuada gestión de la fatiga puede causar alteración en la salud de los trabajadores, asociando la fatiga crónica con el aumento de probabilidad de aparición de enfermedades cardiovasculares, trastornos metabólicos, ansiedad y depresión, junto con la afectación de las relaciones interpersonales.
El propósito principal de este trabajo es realizar la propuesta del diseño del sistema de gestión de fatiga asociada al riesgo psicosocial para los trabajadores en modalidad de trabajo por turnos de la empresa Esenttia, como alternativa para la prevención de accidentes y mejorar la salud de los trabajadores.
Para su desarrollo, como método de investigación se optó por un enfoque mixto, utilizando la investigación cualitativa y cuantitativa para el desarrollo de los objetivos y la comprensión del fenómeno de la fatiga, así como sus causas.
El trabajo incluyó la elaboración de una línea base del estado actual de la fatiga en los trabajadores, mediante la aplicación y revisión de herramientas de diagnóstico para identificar el síntoma subjetivo de fatiga y para evaluar la calidad del sueño, así como el análisis de los resultados de la batería de riesgo psicosocial; de igual manera se definió la metodología para el diseño del sistema mediante la investigación y análisis de la información, para finalmente presentar la propuesta de diseño incluyendo su cronograma de implementación.
La importancia de este trabajo de investigación radicó principalmente en la elaboración de una propuesta de diseño con abordaje sistémico e interdisciplinario de la gestión del riesgo de fatiga, con integración al sistema de gestión de seguridad y salud en el trabajo, así como hacer relevante a nivel de la organización la importancia de la buena gestión del riesgo de fatiga como contribuyente para mantener unas condiciones adecuadas de salud en los trabajadores y la reducción de la probabilidad de ocurrencia de accidentes asociados.Fatigue that results from shift work negatively impacts cognitive and physical responses to demanding situations, leading to slower reaction times and reduced situational awareness. This increases the risk of operational errors and occupational accidents.
Moreover, inadequate fatigue management can significantly affect workers’ health, as chronic fatigue is associated with a higher likelihood of cardiovascular diseases, metabolic disorders, anxiety, depression, and impaired interpersonal relationships.
The goal of this study makes the design proposal of a fatigue management system associated with psychosocial risk for shift workers at the company Esenttia. This proposal aims to prevent accidents and improve workers’ health.
A mixed-method research approach was adopted, combining qualitative and quantitative methods to achieve the objectives and gain a comprehensive understanding of fatigue and its causes. The study included the development of a baseline assessment of workers' current fatigue status through the application and review of diagnostic tools to identify subjective fatigue symptoms and evaluate sleep quality. Additionally, the results of the psychosocial risk assessment battery were analyzed. Based on research and analysis, a methodology was defined for the system’s design proposal, which includes an implementation schedule.
The relevance of this research lies in the development of a design proposal with a systemic and interdisciplinary approach to fatigue risk management. It is integrated into the Occupational Health and Safety Management System and highlights the organizational importance of effective fatigue risk management as a key factor in maintaining workers’ health and reducing the likelihood of associated accidents.Introducción

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
