<p>Numerosos investigadores afirman que la docencia es una profesión altamente estresante, por lo que se convierte en un escenario idóneo para la aparición de burnout (agotamiento emocional, despersonalización y baja autorrealización). No obstante, la atención y estudio de los investigadores acerca del burnout en el campo de la Educación Superior ha sido menor en detrimento de otros niveles y etapas, pese a los cambios y transformaciones que ha experimentado la Educación Superior en los últimos años y que justifican la necesidad de investigación en esta línea. Esta revisión bibliográfica ha tenido como objetivo describir los diferentes objetivos, métodos, instrumentos y variables de investigaciones en este escenario, y así conocer el estado de la cuestión respecto al docente de universidad. Posteriormente, se ha realizado un análisis de las mismas para extraer los datos más importantes de cada investigación y que pueden ser de ayuda para el avance del conocimiento en esta área. Se concluye con una problemática que va acrecentándose y que dificulta el desarrollo profesional del docente de universidad. </p>
Early arrival to breeding grounds is a life history trait in birds that can result in fitness benefits. We studied the relationship between arrival date and breeding success of individuals in a central Iberian population of white stork Ciconia ciconia , between 1999 and 2005, and the ways in which other potential factors, such as age or sex, affect this relationship. Our results showed that age was the factor most closely related to arrival date and breeding success. Older individuals returned earlier to the breeding grounds, achieved larger clutch sizes and produced more chicks than younger birds. After controlling statistically for age effect, breeding probability (laid eggs or not) and laying date were still significantly explained by arrival date. A higher probability of failure to reproduce (no eggs laid) was found in birds arriving later than in those arriving early. However, clutch size and nestling success (number of nestlings in the nest 40 days after hatching) were not correlated with arrival date. Food availability in the study area throughout the breeding cycle, due to a nearby rubbish dump, could be the factor mitigating differences in clutch size and nestling success related to individual arrival date.
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.
