L'accès aux emplois en entreprise des docteurs scientifiques : les impacts des collaborations industrielles
2000
This thesis studies the entrance to firms of the science Ph.D graduates, notably as industrial researcher. Particularly, the impacts of collaborations between the academic sphere and the industry are examined. In this perspective, the first part is dedicated to the elaboration of a frame of analysis. This one establish links between the process of production of the knowledge, the training and the access to the labour market. The analysis of the preparation of the doctorate allows to define both the attributes common to all science Ph.D graduates, and the specific characteristics engendered by the existence of industrial collaborations. The study of the determinants of the access to employme…
Filles et garçons à l'école, approches sociologiques et psycho-sociales. 2e partie : La construction scolaire des différences entre les sexes
1995
International audience; Après avoir examiné, dans une première partie, les différences de scolarisation entre garçons et filles et tenté de rapporter ces différences à des attitudes en grande partie générées dans la famille et l'environnement social, il est temps d'analyser plus précisément cette socialisation qui prend place dans le contexte scolaire, par laquelle l'école participe à la construction des différences entre les sexes. Dans la classe, où ils passent une grande partie de leur temps et se forgent progressivement une image d'eux-mêmes, les enfants reçoivent, au-delà des interactions strictement pédagogiques, une grande quantité d'informations sur les comportements adéquats pour l…

HOLONIC PRODUCTION SYSTEM TO OBTAIN FLEXIBILITY FOR CUSTOMER SATISFACTION
2008
The Holonic Production System (HPS) can be a valid choice to overcome the problems of traditional production sys-tems’ architectures, thanks to its capability to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination. The HPS is made of holons seen as functional production units which are simultaneously autonomous and cooperative. Although the holonic approach could represent a valid solution in order to pursue the necessary levels of agility of production systems, they have been scarcely implemented in practice and even less studied from a business studies perspective. The purpose of this discussion paper is to show the bene…
A method for detecting malfunctions in PV solar panels based on electricity production monitoring
2017
In this paper a new method is developed for automatically detecting outliers or faults in the solar energy production of identical sets (sister arrays) of photovoltaic (PV) solar panels. The method involves a two-stage unsupervised approach. In the first stage, "in control" energy production data are created by using outlier detection methods and functional principal component analysis in order to remove global and local outliers from the data set. In the second stage, control charts for the "in control" data are constructed using both a parametric method and three non-parametric methods. The control charts can be used to detect outliers or faults in the production data in real-time or at t…
Genome-wide association study for milk production traits in an economically important local dairy sheep breed
2021
In this study, we conducted a genome-wide association study (GWAS) for five milk production traits in the Valle del Belice sheep. Repeated measurements for milk yield (MY), fat percentage and yield (F% and FY) and protein percentage and yield (P% and PY) on 481 ewes, were available for the analysis. The animals were genotyped using the Illumina Ovine 50k BeadChip. Weighted deregressed breeding values (DEBVw) were used as phenotypes for GWAS analysis. A total of 23 genome-wide significant SNPs were identified: 3 associated with MY, 9 with FY, and 11 with P%. Several SNPs mapped within known candidate genes or previously reported QTL for milk production traits in livestock species. Additional…
Urban smart mobility in the scientific literature — bibliometric analysis
2018
Abstract This article aims at identification of the main trends in scientific literature characterising urban smart mobility, on the basis of bibliometric analysis of articles published in the ISI Web of Science and Scopus databases. The study period was set from 2000 to 2017. Authors used a basic technique of the bibliometric analysis of the scientific literature characterising urban smart mobility with the support of the VOSviewer software. The analysis included the number of publications, citation analysis, research area analysis and the most frequent keywords. The analysis led to taking notice of current research trends dealing with the urban smart mobility. The core of the paper is a t…
Evaluación de los recursos naturales para un uso y gestión sostenible de la producción agraria en una cuenca del centro-sur de Córdoba (Argentina)
2001
The economical and social development in the Center-South of Cordoba, (Argentina) depends on the agriculture. However, due to low production and severe soil erosion, the farms are not longer economically feasible. This situation implies that the agriculture in the region might not be sustainable in the long run. This study assessed the potential production of the natural resources in the Santa Catalina basin, in order to improve their use and management. The estimated potential production is 300 % higher than the actual production. In addition, the basin is severely affected by water erosion. A new and more sustainable production structure was proposed for the basin, which increases from tr…
The spatial dimension of the French private rental markets: Evidence from microgeographic data in 2015
2021
International audience; This article draws on data collected by local rental observatories in 12 French urban units in 2015 to analyze the spatial dimension of hedonic rental prices in the private rental market through (i) the spatial heterogeneity between urban units and (ii) the wide variety of contextual and locational characteristics (socio-economic, environmental (dis)amenity, and accessibility) and flexible specifications to capture their potential non-linear influence on rent. Based on a joint test of equality of coefficients across all urban units, we find that hedonic prices differ for 75% of the characteristics, thereby justifying a detailed analysis of heterogeneity.

Trayectorias Económicas de las Regiones Españolas en un Escenario Post-crisis: Efectos de Vecindad, Especialización y Aglomeración.
2019
Over the last decade, the Spanish regions have undergone deep economic transformations that have gone hand in hand with changes in the production model. After the bursting of the housing bubble, growth has resumed through a recovery of the international competitiveness and a reorientation towards the foreign market. This new model has a clear territorial dimension visible in terms of unequal regional growth showing specific patterns and driving to a new territorial configuration. In order to define this nee configuration, we shall apply a spatial shift-share analysis to the Spanish regions for the periods 2008-13 (recession) and 2013-17 (recovery) aiming to split growth into its composing e…
