La relación laboral especial y régimen de protección social del servicio del hogar
2016
El presente estudio tiene por objeto el análisis del trabajo doméstico desarrollado en el ámbito de un hogar familiar profesionalmente por las personas dedicadas al servicio y cuidado del mismo. El trabajo al servicio de un hogar familiar, como realidad social, permite abordar un enfoque polivalente, jurídico, social y económico. Una triple realidad que será examinada en el presente trabajo y que condensa los aspectos más relevantes de una actividad marcada por su singularidad, por cuanto la misma es desarrollada en un ámbito tan particular como es un hogar familiar. Desde un punto de vista jurídico, la prestación de servicios remunerados realizada por los trabajadores al servicio del hogar…
Spanish Validation of the Leader Empowering Behavior Questionnaire (LEBQ)
2019
The concept of empowering leadership has attracted widespread academic and practical interest and different questionnaires have been developed to measure it. However, there are no instruments to measure empowering leadership in the Spanish language. This article presents the translation, adaptation, and validation of a scale to measure this construct. In addition, it analyzes the relationship between managers’ empowering leadership and employees’ job satisfaction. In turn, the study analyzes whether employees who participate in a greater number of continuous improvement programs have supervisors who favor more empowering behaviors. A total of 739 participants with various occupations from d…
Nano-structured materials in new and existing buildings: to improved performance and saving of energy
2009
Improving well-being in buildings, in relation to energy conservation, represents a great challenge. In southern Italy a basic problem is that of keeping buildings cool in the summer months. This problem affects not only newly-erected buildings, but also the large number of existing buildings, some of which are of historical importance. Nano-technology represents an excellent opportunity to harness the salvage of existing buildings to the living requirements of contemporary society. The use of nano-structured materials in newly-erected buildings will lead to improved performance and a considerable saving of energy. Above all, the use of nano-structured materials in existing buildings will p…
Design, assembly and characterization of silicide-based thermoelectric modules
2016
ID: 1143 In: Energy conversion and management, 13-21. Summary: Highlights•Novel silicide-based thermoelectric modules were experimentally investigated.•The modules produced high power of 1.04 W at 405 °C and 3.24 W at 735 °C.•An estimated module efficiency of 5.3% represent the highest reported for silicide systems.AbstractSilicides have attracted considerable attention for use in thermoelectric generators due mainly to low cost, low toxicity and light weight, in contrast to conventional materials such as bismuth and lead telluride. Most reported work has focused on optimizing the materials properties while little has been done on module testing. In this work we have designed and tested mod…
History and Environmental Impact of Mining Activity in Celtic Aeduan Territory Recorded in a Peat Bog (Morvan, France)
2003
The present study aims to document historical mining and smelting activities by means of geochemical and pollen analyses performed in a peat bog core collected around the Bibracte oppidum (Morvan, France), the largest settlement of the great Aeduan Celtic tribe (ca. 180 B.C. to 25 A.D.). The anthropogenic Pb profile indicates local mining operations starting from the Late Bronze Age, ca. cal. 1300 B.C. Lead inputs peaked at the height of Aeduan civilization and then decreased after the Roman conquest of Gaul, when the site was abandoned. Other phases of mining are recognized from the 11th century to modern times. They have all led to modifications in plant cover, probably related in part to…
Structural Source of the Trap of ICT Advancement - Lessons from World ICT Top Leaders
2014
In light of the significant consequence of the trap of dramatic advancement of information and communication technology (ICT) in the global economy, both nations and firms that have been compelling their productivity decline. This resulted in great stagnation of ICT advanced economies and therefore its structural sources were analyzed. Based on an empirical analysis tracing, the trend in marginal productivity of ICT and its subsequent prices among the top ICT leaders in the world over the last two decades correlating with the effects of ICT, two faces of ICT advancement were identified. On one side, advancement of ICT contributes to its prices increase by new functionality development, its …
Hybrid moving bed biofilm reactors: a pilot plant experiment.
2008
The growing increment of the urbanization and on the other hand, the even more strict effluent limits imposed by the Water Framework Directive for the receiving water body quality state have lead to a need of upgrading several existing WWTP. With this respect HMBBR systems are an innovative solution since allow to upgrade existing high loaded WWTP without building new tanks. However, some uncertainties in their design, maintenance as well as performance have to be addressed due to their recent acquisition compared with well consolidated technologies such as activated sludge systems. In this light, a data gathering campaign on a HMBBR pilot plant has been performed. The aim was to detect the…
U.I.R.D.A. – Unbuilt Italian Rationalism Digital Archive
2018
For twenty years, the architecture of Italian rationalism through the digital modelling has been investigated. Very often, the production of a model and the consequent representation of tridimensional views, in many case studies, as outcome of the research on architecture have been considered. Actually, the digital model, intended as a critical tool, has to be conceived as a ‘starting point' for graphic analysis of architecture and not as the outcome. Indeed, it is associated to other graphics, sometimes not ‘deducted' from the model, useful for the understanding/translation of architecture. The construction of the model is not the construction of a simple image, operation, which is often c…
Strengthening Safety Compliance in Nuclear Power Operations: A Role-Based Approach
2014
Safety compliance is of paramount importance in guaranteeing the safe running of nuclear power plants. However, it depends mostly on procedures that do not always involve the safest outcomes. This article introduces an empirical model based on the organizational role theory to analyze the influence of legitimate sources of expectations (procedures formalization and leadership) on workers' compliance behaviors. The sample was composed of 495 employees from two Spanish nuclear power plants. Structural equation analysis showed that, in spite of some problematic effects of proceduralization (such as role conflict and role ambiguity), procedure formalization along with an empowering leadership s…
