Antecedents of intensified job demands : evidence from Austria
2019
Purpose In order to understand the driving forces behind intensified job demands (IJDs), the purpose of this paper is to examine demographic factors, structural work-related factors, personal and job resources as antecedents of IJDs. Design/methodology/approach The study is based on cross-sectional (n=4,963) and longitudinal (n=2,055) quantitative data sets of Austrian employees. Data sets were analyzed via regression analyses. Findings The results showed that IJDs, as assessed through five sub-dimensions: work intensification, intensified job-related, career-related planning and decision-making demands, intensified demands for skills and for knowledge-related learning, remained fairly sta…
Élaboration du plan de gestion de l’espace naturel sensible des versants de Vuillafans et Châteauvieux-les-Fossés
2014
The value of the “Espace Naturel Sensible des versants de Châteauvieux et Vuillafans” is based on a natural habitats mosaic that support an originality and a diversity of flora and entomological that we want to preserve. However, in dry grasslands which are habitats of the European community, we can see gradually the emergence of shrub and reforestation due to the difficult to mechanize hills and very fragmented private lands that favored the abandonment of agricultural practices on the slopes. To efficiently program the management of this area, a management plan, which is now a recognize tools for managers of natural areas, was written. To achieve the management plan objectives, the privat…
Security, QoS and self-management within an end-to-end Cloud Computing environment
2015
Today, Cloud Networking is one of the recent research areas within the Cloud Computing research communities. The main challenges of Cloud Networking concern Quality of Service (QoS) and security guarantee as well as its management in conformance with a corresponding Service Level Agreement (SLA). In this thesis, we propose a framework for resource allocation according to an end-to-end SLA established between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) within a Cloud Networking environment (Inter-Cloud Broker and Federation architectures). We focus on NaaS and IaaS Cloud services. Then, we propose the self-establishing of several kinds of SLAs and the self-managemen…
Process intensification in a photocatalytic membrane reactor: Analysis of the techniques to integrate reaction and separation
2017
Abstract Different methods to integrate reaction and separation in a membrane reactor are studied in the present work, with the aim being to highlight the pros and cons of the different alternatives and the effects of the intervening parameters. The coupling of the two processes can take place inside a single apparatus or using separate units. If a single apparatus is utilized, the coupling is more direct, but separate units offer higher degrees of freedom for the design with more opportunities to optimize the system without constraints. However, when using separate units, the integration of the two unit operations depends largely on the parameters intervening in the coupling procedure. The…
The Importance of Recovery from Work in Intensified Working Life
2021
This chapter focuses on intensified working life via the intensified job demands (IJDs) model from the perspective of recovery from work by paying particular attention to the potentially mediating and buffering roles of recovery in the linkages between IJDs and their consequences. In empirical analyses, we examined the buffering role of psychological detachment from work during off-job time in the relationship between intensified job demands and job performance and meaning of work. We found that high psychological detachment, as a recovery experience, buffered against work intensification over time in relation to job performance and meaning of work. Thus, good detachment from work during of…
Introduction du séminaire. Le projet ANR Peerless : viabilité d’une gestion écologique renforcée de la santé des plantes dans les paysages agricoles
2017
Prod 2017-344a SPE équipe EA GESTAD INRA; International audience; L’enjeu du projet PEERLESS (Appel d’offre ANR agrobiosphere, 2012) est de proposer une gestion viable des populations de ravageurs dans les agroécosystèmes par une approche intégrative combinant différentes échelles spatiales, des cultures pérennes et annuelles et les interactions trophiques entre plusieurs ravageurs et leurs ennemis naturels. La régulation des bioagresseurs par les auxiliaires naturellement présents dans les cultures est le service ecosystèmique que l’on souhaite renforcer afin de diminuer la dépendance des systèmes de production agricole aux pesticides. Bien que ces auxiliaires des cultures soient souvent m…

Gestion extensive des surfaces fourragères : menaces et risques de disparition des pratiques bénéfiques pour l’environnement
2014
EA EcolDur; Cet article présente les principaux résultats d’une étude commanditée par le ministère de l’Agriculture, de l’Agroalimentaire et de la Forêt dans le cadre de la préparation de la mise en œuvre des Mesures agro-environnementales et climatiques (MAEC) de la Politique agricole commune pour la période 2014-2020. L’étude a visé à identifier les pratiques de gestion extensive des surfaces fourragères fournissant des services environnementaux, à évaluer les risques de disparition de ces pratiques et déterminer le coût de leur maintien pour un agriculteur. Après une réflexion sur la définition de la gestion extensive en agriculture à différentes échelles spatiales (parcelle, exploitatio…
Harnessing the biodiversity value of Central and Eastern European farmland
2015
A large proportion of European biodiversity today depends on habitat provided by low‐intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly the central and eastern new member states have retained relatively large areas of species‐rich farmland, but despite increased investment in nature conservation here in recent years, farmland biodiversity trends appear to be worsening. Although the high biodiversity value of Central and Eastern European farmland has long been reported, the amount of research in the international literature focused on farmland biodiversity in this region remains comparatively ti…
