Analyse des besoins des employeurs français au regard des compétences en langues vivantes étrangères : synthèse d'enquête
2015
15043; Le rapport d'enquête « Analyse des besoins des employeurs français au regard des compétences en langues vivantes étrangères » constitue l'un des principaux résultats du projet LEMP (Langues et employabilité), conduit en 2014-2015 par un consortium (Ministère de l'Education nationale, de l'Enseignement supérieur et de la Recherche, CIEP, Céreq-IREDU, Onisep, CCI France) avec un partenaire associé (Agence Erasmus+ France | Education Formation). Ce projet est cofinancé par la Commission européenne. Dans ce cadre, plusieurs enquêtes ont été menées et croisées. Via un questionnaire en ligne, le premier volet de l'étude, quantitatif,a permis d'apporter des éclairages sur les modes d'évalua…
Geomaterials in green building practices: comparative characterization of commercially available clay-based plasters
2013
Three pre-mixed powdered clay-based (earthen) plasters produced in Europe and specifically designed for wall undercoating were analyzed in this paper. These materials are commercially available and successfully employed in green building practices all over the world. Their compositional and textural characteristics, as well as plastic behaviour were investigated through a multi-analytical approach: X-ray powder diffraction (XRPD), polarized light microscopy (PLM), X-ray fluorescence spectrometry (XRFS), scanning electron microscopy equipped with an energy dispersive spectrometer (SEM-EDS), mercury intrusion porosimetry (MIP), grain-size distribution (GSD) and semi-empirical tests (Atterberg…
Experimental analysis of a thermoactive underground railway station
2022
Little is known about the real energy potential of thermoactive underground infrastructures, such as railway stations, that can act as a heating/cooling provider for the built environment. This study presents the results of thermomechanical full-scale in situ testing and numerical analysis of a thermoactive underground train station. The thermal performance and related geostructural impact of a portion of the new underground energy infrastructure (UEI) installed at the Lancy-Bachet train station in Geneva (Switzerland) are analyzed. Heating and cooling tests simulating real operative geothermal conditions are considered. Particular attention is given to ((i) the monitored wall-tunnel hydrot…
L'intelligence de l'enfant : l'empreinte du social
2007
07069; L'intelligence en général, l'intelligence de l'enfant en particulier, sont des questions vives, éternellement en débat. Est-il légitime d'évaluer l'intelligence par un chiffre de QI ? L'intelligence est-elle innée ou acquise ? Quel est le rôle de la famille, de l'école, de la société et de la culture dans la genèse de l'intelligence ? Quels enjeux autour de l'inégalité des capacités intellectuelles? Cet ouvrage fait suite à un premier volume qui présentait les nouvelles avancées de la psychologie cognitive. Il réunit un large éventail de travaux qui analysent le rôle de l'environnement dans la définition et le développement de l'intelligence ; ils pointent aussi les multiples enjeux,…
Participer pour rendre le travail possible. Les staffs en unités de soins palliatifs
2018
Répondant à un mandat médical particulier — soigner sans guérir —, les professionnels de soins palliatifs font d’une partie du « sale boulot » hospitalier leur cœur de métier. Dans l’incapacité d’y faire face seuls mais aussi pour lutter contre la souffrance au travail, les médecins attendent des personnels paramédicaux qu’ils participent à l’élaboration du soin à travers des réunions pluridisciplinaires nommées « staff ». Cette participation modifie la division du travail habituellement en vigueur à l’hôpital, et entraîne des « charges de la participation » supplémentaires pour les paramédicaux. Mais dans le même temps, les staffs permettent aux paramédicaux de s’approprier les cadres cult…
TERRE project: interplay between unsaturated soil mechanics and low-carbon geotechnical engineering
2020
The geotechnical construction industry is a major component of the overall construction sector and is strategically important in infrastructure development (transportation, flood and landslide protection, building foundations, waste disposal). Although industry and research in the overall construction sector have been investing significantly in recent years to produce innovative low-carbon technologies, little innovation has been created in geotechnical construction industry, which is lagging behind other construction industry sectors. This paper discusses the interplay between low-carbon geotechnical engineering and unsaturated soil mechanics based on the research carried out within the pr…
Simplified model for compressive response of RC column footing with square cross-section
2017
Abstract In this paper, a simplified calculus model for the prediction of the compressive response of RC column footing with a square cross-section is presented. As it is well-known RC concrete footing are designed adopting uniform contact pressures on the substrate and assuming a strut and tie model in deep members and a cantilever beam or slab model in flexible members. Deep and flexible members are distinguished in literature only based on the tangent of the angle expressed as the ratio between the depth and the shear span of the footing. In this paper, several subgrade contact pressures distribution for column footings (rigid or soft soils) were considered in developing a mechanical 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…
Forest operations in coppice: Environmental assessment of two different logging methods
2016
Wood is a renewable resource and it actively contributes to enhance energy production under a sustainable perspective. However, harvesting, transport and use of wood imply several consequences and impacts on environment. There are different ways for managing forests dedicated to wood production and a sustainable approach is fundamental to preserve the resource. In this context, Life Cycle Assessment (LCA) is a useful tool for estimating the environmental impacts related to renewable resources. Traditional coppice is a common approach for forest management in several areas, including southern Europe and, specifically, Italy, Spain and the Balkans. Due to different terrain conditions, differe…
A novel approach to current transformer characterization in the presence of harmonic distortion
2009
The current transformer (CT) performance under distorted waveform conditions is usually characterized by means of the frequency-response test. In this paper, a new way to characterize CTs, closer to real operation conditions, is proposed. The harmonic phase-angle and ratio errors are measured using a nonsinusoidal current composed of fundamental and one harmonic with adjustable phase shift. The new method was tested by determining the performance of two metering class CTs commonly used by the Italian power company. The errors measured using the proposed approach are larger than the ones obtained with the frequency response. This result suggests that the frequency-response approach for the e…
