L'économie matérielle de la France (1830-2015). L'histoire d'un parasite ?
2018
This article explores the long-term dynamics of material use in France over a period of 185 years. It is based on material flow accounts that are perfectly consistent with the standards of Material Flows Analysis at the national economic scale. This work - which covers domestic extraction, imports and exports - is the first long-term study of material flows for France, with annual and national data for most of the period. Our database allows us to study the evolution of French metabolism during the industrialization of the country, together with the increasing dependence on abiotic materials. We highlight a singular metabolic trajectory: that of a state that benefits from successive world-s…
Évaluations scolaire et pédagogique du travail des collégiens : comparaisons selon les effets simples et intéractifs des caractéristiques personnelle…
2014
L'évaluation scolaire - par les professeurs - est relativement subjective (Gimmonet, 2007). Elle diffère de l'évaluation pédagogique (tests) selon les caractéristiques de l'élève, de l'enseignant et du système scolaire. A ce propos, il n'existerait pas d'étude comparative des deux évaluations selon les effets des caractéristiques de l'élève et du climat social de la classe. Pourtant, il importe de déterminer le rôle des deux groupes de variables et leurs interactions dans l'explication des évaluations scolaire et pédagogique. Ce travail analyse les différences entre ces dernières en fonction des effets simples et interactifs des caractéristiques de l'élève et du climat social de la classe. …

Horizons de justice de l'école, en France et aux États-Unis
2010
Social inequalities of educational careers are stronger in France than in the US, while most of the other indicators of equity are roughly equal. This can be related to the existence of paths in the French educational system, which do not exist in the more comprehensive american systems. More deeply, it can be related to the fact that equity in the US is conceived as fairness of the process of empowerment of students while it is conceived in France as the independence of the educational merit with the social capital.
Intraocular pressure and central corneal thickness in an old French population: The MONTRACHET study
2013
Purpose: To describe the distribution of intraocular pressure (IOP) and central corneal thickness (CCT) in an old French population. Methods: About 9000 individuals 65 years and older were included in the 3C cohort study since 1999 in 3 French cities (Bordeaux, Dijon and Montpellier). In Dijon, an additional ophthalmic examination was performed 10 years after the initial inclusions to assess the relation between systemic age-related diseases and eye diseases in the MONTRACHET Study (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases). In this population-based stuy a thorough eye examination and a questionnaire were undertaken in each participant. Intraocular pressure (IOP) 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.
On-Demand Security Framework for 5GB Vehicular Networks
2023
Building accurate Machine Learning (ML) at-tack detection models for 5G and Beyond (5GB) vehicular networks requires collaboration between Vehicle-to-Everything (V2X) nodes. However, while operating collaboratively, ensuring the ML model’s security and data privacy is challenging. To this end, this article proposes a secure and privacy-preservation on-demand framework for building attack-detection ML models for 5GB vehicular networks. The proposed framework emerged from combining 5GB technologies, namely, Federated Learning (FL), blockchain, and smart contracts to ensure fair and trustedinteractions between FL servers (edge nodes) with FL workers (vehicles). Moreover, it also provides an ef…
