L'organisation de l'université française à la lumière de ses processus de certification
1984
International audience; L'assimilation de l'école à la firme multiproduit autonomie soulève de nombreuses difficultés contextuelles. Malgré tout, l'utilisation au cas de l'établissement scolaire des outils classiques de la théorie économique de la production est susceptible de rendre compte des conséquences de ses pratiques éducatives sur un mode de fonctionnement. En faisant référence à ce cadre d'analyse, le propos de l'auteur est de révéler ici l'organisation actuelle de l'université française en examinant le rôle des divers acteurs dans le processus de production de diplômés et de vérifier, en définitive, l'existence d'un assortiment entre les établissements et leurs publics étudiants, …

Performances linguistiques des enseignants et qualité d'apprentissage des élèves au primaire
2011
In a broad sense Education for All (EFA) is a hazardous Issue for to the least developed countries, and yet it adds, almost always, for these countries to provide additional difficulty for initial learning periods when majority in pupils has to assume the route from the local language to the teaching one. Besides, adapting in this context the provision of education has often done under the financial constraint. The hiring for supplementary teachers, as to reach EFA goal, less paid in comparison to their older colleagues. So now the teacher staff is consequently represented by new teachers with fewer initial education and pedagogical training, but definitely closer to the communities. The re…
Développement et caractérisation d’électrodes pour l’électrolyse alcaline de l’eau
2020
Splitting water into hydrogen and oxygen by electrolysis using electricity from intermittent ocean current, wind, or solar energies is one of the easiest and cleanest routes for high-purity hydrogen production and an effective way to store the excess electrical power without leaving any carbon footprints. The key dilemma for efficient large-scale production of hydrogen by splitting of water via the hydrogen and oxygen evolution reactions is the high overpotential required, especially for the oxygen evolution reaction. Hence, engineering highly active and stable earth-abundant oxygen evolution electrocatalysts with three-dimensional hierarchical porous architecture via facile, effective and …

Les limites de la théorie du salaire d'efficience
1998
Efficiency wage theory, evolved by the "new keynesians", is part of a research programme concerned with explaining "involuntary" unemployment as part of the "general equilibrium". So, these works are a synthesis attempt of neo-classical and keynesian analyses in the employment area. Indeed, the authors place their analysis in a walrasian framework, but they integrate a keynesian concept to complete their models. In order to achieve their purpose, the efficiency wage theorists formulate two propositions on which their argument is based: 1° the relation supposed rising between the rate of wage and the productivity of wage earners, 2° the determination of the rate of wage outside the market. W…
Genetic variability at αs2-casein gene in Girgentana dairy goat breed
2014
Casein genes are highly polymorphic and the high degree of variability has qualitative and quantitative effects on milk composition thereby affecting chemical, physical and technological properties of goat milk. The aim of this work was to evaluate the genetic polymorphisms of the αs2-casein (CSN1S2) gene in the endangered Girgentana dairy goat breed in order to assess the genotypes distribution, as it is known genotype influences technological and nutritional milk properties. The study was performed on 207 sample of Girgentana goat breed, analysed with different PCR protocols. The most frequent alleles was A (0.722), followed by F (0.225), C (0.051) and E (0.002) while B, D and 0 alleles w…
Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment
2018
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ+ℓ−c¯c is studied. A data set with an integrated luminosity of 36.1 fb−1 of pp collisions at √s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→c¯c signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(pp→ZH)×B(H→c¯c) is 2.7 (3.9+2.1−1.1) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
