Le travail, au-delà de l'évaluation : normes et résistances
2018
National audience; Certains milieux de travail connaissent une véritable inflation des normes. Leurs finalités sont multiples : instaurer de la transparence, garantir au « client » un service de qualité, orienter et contrôler les comportements, responsabiliser les acteurs et les inciter à « l'excellence », mieux évaluer le personnel. En constituant un véritable corset, voire un carcan, ces normes peuvent empêcher les salariés de réaliser un travail de qualité, être une source de démotivation - voire de souffrance au travail - et fragiliser les collectifs de travail en place. Elles peuvent aussi générer des actions de résistance, individuelles et/ou collectives. Damien Collard invite le lect…
Evaluation of the electrochemical anion recognition ofNO3−-imprinted poly(Azure A) inNO3−/Cl−mixed solutions by ac-electrogravimetry
2016
Abstract During the reversible electrochemical reactions of the intrinsically conducting polymer (ICP) films, ions are inserted in them to balance the inner charge site of the polymer. For this reason, doped ICP films with anions or cations can be good candidates for the electrochemical removal of contaminant ions from wastewater. In this work, a polymer of a phenothiazine derivative (poly(Azure A or PAA)) was electrosynthesized by cyclic voltammetry in aqueous solutions using nitrate ions as a structural template. After that, PAA film was repeatedly cycled in identical conditions in a monomer-free solution. The electrochemical anion recognition of the nitrate-imprinted poly(Azure A) ( N O …
Dynamic preparation of TiO2 films for fabrication of dye-sensitized solar cells
2006
Preparation of nanocrystalline porous titanium dioxide (TiO2) films with roll-to-roll compatible methods was studied. Gravure printing was used for spreading TiO2 paste and paper calendering for pressing TiO2 nanoparticle films. Influence of different preparation methods on performance of fabricated dye-sensitized solar cells (DSSCs) was investigated. The attained light into electricity conversion efficiency was compared with DSSCs fabricated on conductive plastic substrates by doctor-blading spreading with subsequent static pressing. The latter method achieved a light conversion efficiency as high as 5.1%. The efficiency of the cells with a gravure printed TiO2 film was found to be rather …

On Severi Type Inequalities for Irregular Surfaces
2017
Let X be a minimal surface of general type and maximal Albanese dimension with irregularity q ≥ 2. We show that K2 X ≥ 4χ(OX) + 4(q − 2) if K2 X < 9 2 χ(OX), and also obtain the characterization of the equality. As a consequence, we prove a conjecture of Manetti on the geography of irregular surfaces if K2 X ≥ 36(q−2) or χ(OX) ≥ 8(q−2), and we also prove a conjecture that the surfaces of general type and maximal Albanese dimension with K2 X = 4χ(OX) are exactly the resolution of double covers of abelian surfaces branched over ample divisors with at worst simple singularities.
External knowledge sourcing in different national settings: a comparison of electronics establishments in Britain and France
2004
04001; International audience; In a detailed comparison of matched samples of electronics establishments in Britain and France, this paper finds that the two samples of establishments were operating in distinctively different national labour markets for engineers and scientists, reflecting structural differences in national higher education systems and a far higher level of individual mobility between enterprises in Britain than is found in France. These differences were found to have very little effect on quantitative measures of establishments' external research interactions which tended to reflect other national-institutional differences such as continued government support for public la…
Contribution pour une connaissance praticable du travail émotionnel des télé-conseillers
2013
Dans les centres d’appels, les télé-conseillers sont tenus d’émettre des comportements prescrits par le management dans le but d’augmenter la satisfaction de la clientèle. Toutefois, lors des conversations, ils n’arrivent pas toujours à cacher leurs vraies émotions. Ce comportement risque d’entraîner des pertes de clientèle. En se fondant sur le cadre théorique du travail émotionnel, la présente étude a pour finalité de cerner les principales causes des comportements adéquats ou déviants des télé-conseillers lors des conversations téléphoniques. Cet article montre que ce sont principalement les situations d’interaction (charge de travail, heure de l’appel) ainsi que les règles établies par …
A GIS-MCDM-based road network planning for tourism development and management in Arasbaran forest, Iran.
2019
It is very important for managers to plan a road network that meets all the requirements for tourism development and management. The aim of this study was to evaluate and modify an existing road network for tourism purposes in the Arasbaran protected area. First, the map layers of effective criteria were prepared in GIS and were standardized by a fuzzy logic approach and finally combined considering their relative importance weights obtained through pair-wise comparison technique. A suitability map was then acquired. After that, 14 different scenarios of road network were designed to access the recreational area using PEGGER extension in ArcView. Then, they were evaluated in terms of techni…
