During the transit of students in the acquisition of competencies that allow them a good future development of their profession, they face the constant challenge of overcoming academic subjects. According to the learning theory, the probability of success of his studies is a multifactorial problem, with learning-teaching interaction being a transcendental element (Muñoz-Repiso and Gómez-Pablos in Edutec. Revista Electrónica de Tecnología Educativa 52: a291-a291 (2015), [1]. This research describes a predicative model of academic performance using neural network techniques on a real data set.
El derecho laboral está caracterizado por desarrollar dentro de sus principios, la igualdad y la justicia como elementos propositivos basados en la argumentación de las normas laborales que constituyen fundamentos para promover la eficiencia productiva y la justicia social. En este orden de ideas, el objetivo del presente artículo de reflexión, es analizar bajo una metodología cualitativa con enfoque documental, los diferentes pronunciamientos dados por los Altos Tribunales colombianos frente a algunos eventos en donde a los trabajadores se les brindó estabilidad reforzada y las consecuencias de no cumplir con los procedimientos establecidos para desvincular a estos de sus trabajos. Concluyendo que fue posible evidenciar a partir de las sentencias analizadas sobre estabilidad laboral reforzada, el garantismo brindado por esta vía a los diferentes trabajadores, lo cual implica que los empleadores se vean obligados a cumplir con unos formalismos particulares al momento de terminar relaciones laborales en los sujetos de especial protección.
In the present work, the dimensions of the psychosocial risk assessment instrument are defined considering internal, individual, double presence and external factors for work environments. Those corresponding to internal, individual and double presence factors are not subject to a process of validation of content since they come from the ISTAS 21 model validated by the Trade Union Institute of Labor, Environment and Health of Spain. The variables corresponding to external factors are obtained from the Social Determinants of Health Model of the World Health Organization. These measurement tools are used for companies with a high number of workers, so a large amount of data is generated. The construct validity of the external factors is carried out by calculating the sample adequacy measure of Kaiser-Meyer-Olkin together with the Bartlett sphericity test and the communalities analysis. Of the internal and individual variables there are twenty dimensions and of the external variables, are reduced to 14.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
