Exploring the relationships between high involvement work system practices, work demands and emotional exhaustion: a multi-level study.
2016
This study explores the impact of enacted high involvement work systems (HIWS) practices on employee emotional exhaustion. This study hypothesized that work overload and job responsibility mediate the relationship between HIWS practices (ability, motivation, opportunity and work design HIWS practices) and employee emotional exhaustion. A total of 360 employees (nested within 49 work units) rated their feelings of work overload, job responsibility and emotional exhaustion. The line managers from these work units rated the enacted HIWS practices. Results indicate that ability- and motivation HIWS practices are positively related to work overload, and ability-, motivation- and work design HIWS…
Suddenly Working From Home!
2022
Abstract. The Corona crisis and the lockdown in the spring of 2020 had various effects on working life in Europe. In this three-wave study, we assessed the trajectories of job demands and resources of 302 employees 2 weeks before the lockdown, over 1 week after lockdown start, and 6 weeks following the beginning of the lockdown. We applied a pre-post follow-up design with 129 employees who switched to telecommuting and a control group of 173 employees who remained in their on-site workplace. Results from the repeated-measures MANCOVA indicate that, despite various general changes to job characteristics because of the Corona crisis, telecommuting changes contributed to significant changes on…
Profiling development of burnout over eight years: relation with job demands and resources
2020
The aim of the present study was twofold: First, to profile the long-term development of burnout symptoms (exhaustion, cynicism and reduced professional efficacy), and second, to investigate the associations of developmental burnout profiles with job demands and resources. The study focused on Finnish white-collar professionals (N = 169) who participated in a survey five times during eight years (in 2006, 2008, 2010, 2012, and 2014). At each measurement time, the participants filled in the same scales of burnout, job demands and job resources. Using Latent Profile Analysis (LPA), three developmental profiles of burnout symptoms were identified: 1) Stable, low burnout (78%), 2) Exhaustion in…
Objective work–nonwork conflict: From incompatible demands to decreased work role performance
2011
Research on work–nonwork conflict (WNC) is based on the assumption that incompatible demands from the work and the nonwork domain hamper role performance. This assumption implies that role demands from both domains interact in predicting role performance, but research has been largely limited to main effects. In this multi-source study, we analyze the incompatibility of demands by testing the interaction of work and nonwork demands on task performance and organizational citizenship behavior (OCB). The sample consisted of 61 employees of a German hospital and we used three independent sources of data: self-ratings of work demands, partner-ratings of nonwork demands, and colleague-ratings of …
La alteridad en el discurso de la ciencia ficción : identidad y desarraigo en Beforeigners (HBO: 2019- )
2021
La representación del miedo hacia el Otro ha sido una de las temáticas más recurrentes en el género de la ciencia ficción. En esta línea, esta investigación articula un análisis de la serie noruega Beforeigners en torno al discurso de la identidad. Desde una perspectiva cualitativa, se ha realizado un análisis textual que ha puesto de manifiesto que en la serie prevalecen los valores comunitarios y solidarios. En la discusión se han contrapuestos los resultados con otras series del género y se ha evidenciado que la serie rompe con las narrativas típicas de la ciencia ficción. Asimismo, se destaca el tono crítico de la serie hacia las políticas de inmigración de la Unión Europea. The portray…
Privacy-Preserving Overgrid: Secure Data Collection for the Smart Grid
2020
In this paper, we present a privacy-preserving scheme for Overgrid, a fully distributed peer-to-peer (P2P) architecture designed to automatically control and implement distributed Demand Response (DR) schemes in a community of smart buildings with energy generation and storage capabilities. To monitor the power consumption of the buildings, while respecting the privacy of the users, we extend our previous Overgrid algorithms to provide privacy preserving data aggregation (PP-Overgrid). This new technique combines a distributed data aggregation scheme with the Secure Multi-Party Computation paradigm. First, we use the energy profiles of hundreds of buildings, classifying the amount of &ldquo
Refractory organic pollutants and toxicity in pulp and paper mill wastewaters
2015
This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry. The aim is to review the versatile pollutants and the analysis methods for their determination. Among other pollutants, biocides, extractives, and lignin-derived compounds are major contributors to harmful effects, such as toxicity, of industrial wastewaters. Toxicity of wastewaters from pulp and paper mills is briefly evaluated including the methods for toxicity analyses. Traditionally, wastewater purification includes mechanical treatment followed by chemical and/or biological treatment processes. A variety of methods are available for the purification of industrial w…
Flexible Data Driven Inventory Management with Interactive Multiobjective Lot Size Optimization
2021
We study data-driven decision support and formalise a path from data to decision making. We focus on lot sizing in inventory management with stochastic demand and propose an interactive multi-objective optimisation approach. We forecast demand with a Bayesian model, which is based on sales data. After identifying relevant objectives relying on the demand model, we formulate an optimisation problem to determine lot sizes for multiple future time periods. Our approach combines different interactive multi-objective optimisation methods for finding the best balance among the objectives. For that, a decision maker with substance knowledge directs the solution process with one’s preference inform…
Adaptive plasticity of blue tits(Parus caeruleus)and great tits(Parus major)breeding in natural and semi‐natural insular habitats
2004
The breeding performance and foraging of blue and great tits, and the abundance of arthropods living on the trees of an oak-wood and of a coniferous reafforestation were studied in Sicily, in order to: 1) compare breeding parameters in natural and semi-natural habitats within the same area; 2) estimate the degree of overlap in peak resource and peak demand of young tits, and the overlap of nestling diet of the two species in the two habitats. Both species had earlier laying dates, laid more eggs and raised more fledglings in the oakwood than in the reafforestation; they achieved the same fledging success within the same habitat type. These differences are probably due to the earlier and hig…
Santé : des métiers encore protégés
1994
International audience; Les métiers de la santé se caractérisent par des effectifs en croissance, une féminisation importante et des emplois protégés. Parmi les actifs occupés en Bourgogne, les professionnels de la santé occupent une place à part, avec un ensemble organisé de formations spécifiques qui permettent, dès l'obtention du diplômes, d'exercer le métier appris et d'avoir la reconnaissance d'un statut précis. Dans le secteur de la santé, on observe une relation relativement étroite entre les composantes formation, emploi et statut social.
