Algunes aportacions de la psicologia social a la psicologia de la salut ocupacional
2010
L'objectiu d'aquest estudi és presentar una revisió sobre les característiques de la Psicologia de la salut ocupacional 'd'ara endavant, PSO' i algunes de les contribucions principals que la Psicologia social ha fet al seu desenvolupament, com a disciplina científica i cos de coneixements. L'estudi comença amb una presentació d'alguns dels canvis que han tingut lloc en les últimes dècades i que han afavorit l'aparició de la PSO. En el segon punt, s'hi aborda el concepte, els orígens i els objectius de la PSO. A continuació, s'hi revisen els mètodes d'investigació que han utilitzat els acadèmics i professionals de la PSO, i s'hi distingeix entre els mètodes d'investigació quantitatius i qual…
Cognitive processes of emotional regulation, burnout and work engagement
2019
Workers constantly resort to cognitive processes of emotion regulation to deal with emotions they experience in the workplace. These processes belong either to the 'automatic' (preconscious and fast) or the 'elaborative' (conscious and slow) mode. This study aims to determine the role of these variables in the work setting and to analyze their relationship with positive and negative affect, engagement and burnout. Method: 350 employees (54.8% men and 45.2% women) were presented with several instruments measuring burnout, engagement, affect and cognitive emotion regulation strategies in a prospective study. An explanatory model was tested through structural equation modeling analysis. Result…
Preparation and characterization of dummy-template molecularly imprinted polymers as potential sorbents for the recognition of selected polybrominate…
2018
The main aim of this work was to conduct the preliminary/basic research concerning the preparation process of a new dummy molecularly imprinted polymer (DMIP) materials. Developed DMIPs were proposed as a sorption material in solid-phase extraction (SPE) technique for recognition of selected low mass polybrominated diphenyl ethers (PBDEs) – PBDE-47 and PBDE-99. Four new DMIPs were synthesized employing bulky polymerization technique by application of structural analogue of low mass PBDEs - 4,4′-Dihydroxydiphenyl ether, as a dummy template. The DMIPs and corresponding non-imprinted polymers were prepared using different functional monomers: methacrylic acid; methyl methacrylate and different…
La evaluación en Formación Profesional como mejora del proceso enseñanza aprendizaje en la resolución de problemas
2016
Desde nuestra perspectiva profesional concebimos la evaluación como una acción inherente y simultánea al quehacer educativo que posibilita la toma de decisiones para mejorar el rendimiento y la comprensión del alumnado sobre lo que se hace en las aulas de Formación Profesional y cómo se hace. Esta experiencia se contextualiza en el Ciclo Formativo de Grado Superior “Gestión Comercial y Marketing". El proceso de evaluación del proyecto resolución de problemas sobre gestión de stocks se desarrolla en tres momentos: evaluación diagnóstica/inicial, evaluación durante el proceso y evaluación final. Los docentes pretendemos implicar al alumnado de la asignatura Logística Comercial en los procedim…
Global collaborative networks on meta-analyses of randomized trials published in high impact factor medical journals: a social network analysis
2014
Abstract Background Research collaboration contributes to the advancement of knowledge by exploiting the results of scientific efforts more efficiently, but the global patterns of collaboration on meta-analysis are unknown. The purpose of this research was to describe and characterize the global collaborative patterns in meta-analyses of randomized trials published in high impact factor medical journals over the past three decades. Methods This was a cross-sectional, social network analysis. We searched PubMed for relevant meta-analyses of randomized trials published up to December 2012. We selected meta-analyses (including at least randomized trials as primary evidence source) published in…
Experimental increase of worker diversity benefits brood production in ants
2021
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness. However, many extant eusocial species have developed strategies that decrease genetic relatedness in their colonies, suggesting some benefits of the increased diversity. Multiple studies support this hypothesis by showing positive correlations between genetic diversity and colony fitness, as well as finding effects of experimental manipulations of diversity on colony performance. However, alternative explanations could account for most of these reports, and the benefits of diversity on performance in eusocial insects stil…
Indemnización y trabajador en excedencia afectado en expediente de regulación de empleo
2021
espanolEn este trabajo se realiza un analisis de los derechos del trabajador en excedencia voluntaria que se encuentra afectado en un expediente de regulacion de empleo, concretamente, del derecho a recibir la correspondiente indemnizacion por despido colectivo o no. La doctrina judicial y jurisprudencial ha negado que el trabajador excedente incurso en un expediente de regulacion de empleo tenga derecho a la misma. No obstante, ello va unido a la posicion que se tenga sobre la naturaleza juridica de la excedencia voluntaria, aspecto debatido entre la doctrina, tanto cientifica como judicial. En este sentido, una linea doctrinal ha considerado que la excedencia voluntaria tiene un caracter …
A gesture recognition framework for exploring museum exhibitions
2018
In this paper we present a gesture recognition framework for providing the visitors of a museum exhibition with a non intrusive interface for the multimedia enjoyment of digital contents. Early experiments were carried out at the Computer History Museum Exhibition of the University of Palermo.
FISH: Face Intensity-Shape Histogram representation for automatic face splicing detection
2019
Abstract Tampered images spread nowadays over any visual media influencing our judgement in many aspects of our life. This is particularly critical for face splicing manipulations, where recognizable identities are put out of context. To contrast these activities on a large scale, automatic detectors are required. In this paper, we present a novel method for automatic face splicing detection, based on computer vision, that exploits inconsistencies in the lighting environment estimated from different faces in the scene. Differently from previous approaches, we do not rely on an ideal mathematical model of the lighting environment. Instead, our solution, built upon the concept of histogram-ba…
Scientific studies on writing in second language learning (2005-2017)
2019
Este artículo revisa críticamente las líneas temáticas que desde 2005 hasta 2017 se han publicado sobre Second Language Writing (SLW) con el objetivo de presentar un análisis de las tendencias predominantes en las publicaciones indexadas en SCOPUS. Como metodología de estudio se ha procedido a la selección de aquellas contribuciones que han recibido 60 citas o más. De la revisión de literatura científica realizada se concluye que son tres las líneas de investigación mayoritarias: el proceso de composición o redacción del texto escrito; la retroalimentación que el docente ofrece al aprendiz; y la escritura en línea de una L2. Las conclusiones señalan la necesidad de profundizar en la investi…
