Une sélection parmi d'autres : les déterminants du souhait d’études supérieures des bacheliers professionnels
2020
International audience; Depuis le milieu des années 2000 et plus particulièrement depuis 2010, les opportunités d’études supérieures des bacheliers professionnels n’ont cessé de croître. Néanmoins, du projet scolaire à l’obtention d’un diplôme, en passant par l’admission dans une formation, leur parcours semble encore jonché d’obstacles. L’augmentation du taux de poursuite d’études des bacheliers professionnels signifie-t-elle que l’enseignement supérieur se démocratise? Les portes de l’enseignement supérieur sont-elles restées «entrouvertes» aux bacheliers professionnels(Lemêtre, Mengneau & Orange, 2016)?Ce travail explore les enjeux des poursuites d’études supérieures des bacheliers profe…
EARLY DEVELOPMENT ECONOMICS DEBATES REVISITED
2007
Development economics in its early years created the image of a fierce fight between advocates of contrasting theories or approaches—“balanced growth” vs. “unbalanced growth,” or “program loans” vs. “project loans.” This view has the merit of highlighting such conflicts in great detail; yet, it fails to take into account the reality of development economics as it was practiced in the field. This paper reassesses these old conflicts by complementing the traditional focus on theoretical debates with an emphasis on the practice of development economics.A particularly interesting example is the debate between Albert Hirschman, one of the fathers of the “unbalanced growth” approach, and Lauchlin…
Baisse soutenue de l'embauche des jeunes
2014
En Bourgogne, près de 8 300 jeunes ont quitté les classes terminales professionnelles et technologiques du lycée et de l'apprentissage en juin 2012. Sept mois plus tard, 53 pour cent des garçons et 46 pour cent des filles ont trouvé un emploi non aidé. Les effets de la crise perdurent : en 2013 l'économie régionale a perdu 4 200 emplois salariés. Cette dégradation induit une augmentation du chômage des jeunes, quel que soit le mode de formation. Dans un contexte marqué aussi par la réforme de la voie professionnelle, la hiérarchie des diplômes n'est toutefois pas remise en cause. Un niveau d'études plus élevé demeure un atout sur le marché du travail en termes d'accès à l'emploi et de condi…
Maintien de l'emploi des jeunes en Bourgogne début 2014
2015
En Bourgogne, 8 100 jeunes ont quitté les classes terminales professionnelles et technologiques du lycée ou de l'apprentissage en juin 2013. Sept mois plus tard, 54 pour cent des garçons et 48 pour cent des filles occupent un emploi non aidé. Les jeunes bénéficient de l'accalmie perceptible en Bourgogne en fin d'année 2013 et début 2014. Leur situation professionnelle reste stable par rapport à la promotion précédente. Toutefois, la transition sur le marché du travail s'est aggravée après un CAP, quel que soit le mode de formation.
Influence of correlations between stresses on calculated fatigue life of machine elements
1996
The correlation between components of the random stress tensor and its influence on the calculated fatigue life of machine elements were analysed. Three covariance matrices of components of biaxial stress state were considered. They were determined from measurements of strains in an element of a vibrating screen for aggregate, in the back wall of a bus, and in a welded element of excavator fittings. Calculations were made according to four criteria of multiaxial random fatigue. Cycles were counted with the rainflow method, and damage was cumulated with the Palmgren-Miner hypothesis. It was found that convariances of random stress state components strongly influence the calculated fatigue li…
Covariance between components of biaxial stress state in fatigue life calculations
1992
In this paper influence of correlalions between components of random stress tensor on the calculated fatigue life of the machine element has been analysed. Two groups of covariance matrices for components of biaxial stress state were considered. The first group was arbitrarily assumed and the second one was determined on the basis of the measured strains in the element of the vibrating screen for aggregate. Computer simulation was realized with four criteria of multiaxial random fatigue. Cycles were counted with the method of rain flow and damages were cumulated according to Palmgren-Miner hypothesis. It has been shown that covariances between components of stress state tensor strongly infl…
Comparison of the Rain Flow Algorithm and the Spectral Method for Fatigue Life Determination Under Uniaxial and Multiaxial Random Loading
2008
This paper presents the strain energy density parameter used for fatigue life calculation under random loading by two methods. The first method is based on schematization of energy parameter histories with the rain flow algorithm. The other one is based on moments of the power spectral density function of the energy parameter. The experimental data of fatigue tests of 10HNAP steel under constant amplitude and random uniaxial loading with non-gaussion probability distribution, zero mean value, and wide-band frequency spectrum used for comparison of the rain flow algorithm and the spectral method gave satisfactory results. Next, histories of the random stress tensor with normal probability di…
Etalement urbain et consommation d'espace. Etude comparée de Besançon, Belfort et Montbéliard
2007
Urban sprawl constitutes a specific case of urbanization that is currently common in French cities. Arising from significant development of suburbs, it inevitably leads to the increase of built-up surfaces in every periurban area. At the same time, we can assume that urban sprawl induces over-consumption of space. This assumption is tested on the three main towns of Franche-Comté, that are associated with very different geographical, demographic and industrial characteristics (these characteristics are briefly described). The study confirms, in general, the reality of over-consumption of space, dependant on urban sprawl ; it seems generally independent of the individual characteristics of e…
Hemochromatosis Mimicked Gaucher Disease: Role of Hyperferritinemia in Evaluation of a Clinical Case.
2022
Gaucher disease is a disorder of lysosomes caused by a functional defect of the glucocerebrosidase enzyme. The disease is mainly due to mutations in the GBA1 gene, which determines the gradual storage of glucosylceramide substrate in the patient’s macrophages. In this paper, we describe the case of a 38-year-old man who clinically presented with hyperferritinemia, thrombocytopenia, leukopenia, anemia and mild splenomegaly; a diagnosis of hemochromatosis was made 10 years earlier. Re-evaluation of the clinical case led to a suspicion of Gaucher disease, which was confirmed by enzymatic analysis, which was found to be below the normal range, and genetic evaluation, which identified compound h…
Functional and genetic characterization of the non-lysosomal glucosylceramidase 2 as a modifier for Gaucher disease.
2013
Background: Gaucher disease (GD) is the most common inherited lysosomal storage disorder in humans, caused by mutations in the gene encoding the lysosomal enzyme glucocerebrosidase (GBA1). GD is clinically heterogeneous and although the type of GBA1 mutation plays a role in determining the type of GD, it does not explain the clinical variability seen among patients. Cumulative evidence from recent studies suggests that GBA2 could play a role in the pathogenesis of GD and potentially interacts with GBA1. Methods: We used a framework of functional and genetic approaches in order to further characterize a potential role of GBA2 in GD. Glucosylceramide (GlcCer) levels in spleen, liver and brain…
