Autonomie et choix des établissements scolaires
2001
Une évolution majeure des systèmes éducatifs est l'accroissement des prérogatives des établissements scolaires et celui de la possibilité pour les parents de choisir l'établissement de leurs enfants. Cette revue de la littérature de recherche, en France et à l'étranger, aborde les thèmes suivants, successivement pour chacun de ces deux thèmes : Environnement et objectifs politiques de ces décisions, les raisons que la théorie sociologique ou économique donne de les approuver ou de les critiquer, les formes précises qu'elles prennent dans les différents pays développés, leur degré de mise en oeuvre, et enfin ce que l'on peut savoir de leurs effets sur l'efficacité et l'équité des systèmes éd…

Qualité et efficience de l'école primaire française : éléments de comparaisons spatiales et temporelles
2008
08001 - 20 p.; Document de travail de l'IREDU 2008-01; L'objectif principal de ce texte est de présenter des éléments factuels sur les résultats de l'école primaire française. Notre réflexion portera sur deux dimensions complémentaires, à savoir la qualité et l'efficience, celles-ci seront examinées dans une double perspective comparative (temporelle et spatiale). Dans une première partie, nous mobiliserons les données des enquêtes internationales pour apprécier les résultats des élèves français et leur évolution dans le temps sur ces 15 dernières années. La seconde partie sera consacrée aux coûts de l'enseignement primaire et plusieurs aspects seront abordés. Dans un premier temps, l'évolu…
Comparative genomics and protein domain graph analyses link ubiquitination and RNA metabolism.
2006
The human gene parkin, known to cause familial Parkinson disease, as well as several other genes, likely involved in other neurodegenerative diseases or in cancer, encode proteins of the RBR family of ubiquitin ligases. Here, we describe the structural diversity of the RBR family in order to infer their functional roles. Of particular interest is a relationship detected between RBR-mediated ubiquitination and RNA metabolism: a few RBR proteins contain RNA binding domains and DEAH-box RNA helicase domains. Global protein domain graph analyses demonstrate that this connection is not RBR-specific, but instead many other proteins contain both ubiquitination and RNA-related domains. These protei…
Eurosceptic Contagion and European Elections
2021
At the onset, the starting perspective here has been that the main arena for political struggle is the national one. One of the most influential approaches in the study of European and European Union politics has been the second-order election thesis (Reif & Schmitt, 1980). According to this school of thought, elections to the European Parliament have actually functioned as somewhat less important national elections (hence second order, akin to US midterm elections), and the main arena for political conflict over EU policy lies at the national level. This book has so far largely shared these assumptions and premises and has as a consequence focused on the effect of Eurosceptic Parties’ succ…
Low Degree of Separation Does Not Guarantee Easy Coordination
2012
In the times of increased global competition, software companies are forced to search for more effective development practices and often team up with onshore and offshore partners to develop faster and better products. In this paper we empirically explore a highly distributed onshore development project with a complex coordination structure. Our findings demonstrate that onshore development projects are not protected from coordination and communication challenges and task allocation complexities. Previously reported qualitative findings regarding organizational problems in this paper are supplemented with quantitative measurements of the true coordination delays and additional analysis of c…
An Innovative Ambient Identification Method
2020
Ambient modal identification, also known as Operational Modal Analysis (OMA), aims to identify the modal properties of a structure based on vibration data collected when the structure is under its operating conditions, i.e., no initial excitation or known artificial excitation. This procedure for testing and/or monitoring historic buildings, is particularly attractive for civil engineers concerned with the safety of complex historic structures. However, since the external force is not recorded, the identification methods have to be more sophisticated and based on stochastic mechanics. In this context, this contribution will introduce an innovative ambient identification method based on appl…
An integrated methodological approach for optimising complex systems subjected to predictive maintenance
2021
Abstract The present paper addresses the relevant topic of maintenance management, widely recognised as a fundamental issue involving complex engineering systems and leading companies towards the optimisation of their assets while pursuing cost efficiency. With this regard, our research aims to provide companies with a hybrid methodological approach based on Multi-Criteria Decision-Making (MCDM) capable to deal with the main failures potentially involving complex systems subjected to predictive maintenance. Such an approach is going to be integrated within the framework of traditional Failure Mode Effects and Criticality Analysis (FMECA), whose strengths and weaknesses are considered. In pa…
