Interannual memory effects for spring NDVI in semi-arid South Africa
2008
[1] Almost 20 years of Normalized Difference Vegetative Index (NDVI) and precipitation (PPT) data are analysed to better understand the interannual memory effects on vegetation dynamics observed at regional scales in Southern Africa (SA). The study focuses on a semi-arid region (25°S–31°S; 21°E–26°E) during the austral early summer (September–December). The memory effects are examined using simple statistical approaches (linear correlations and regressions) which require the definition of an early summer vegetation predictand (December NDVI minus September NDVI) and a consistent set of potential predictors (rainfall amount, number of rainy days, rainfall intensity, NDVI and Rain-Use-Efficie…
L'efficacité des privatisations françaises : une vision dynamique à travers la théorie de la gouvernance
2004
International audience; A reading of the process of privatization through the corporate governance theory leads to propose a model taking into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After replicating some traditional tests, we test this model on a sample of French privatized firms and on a seven years horizon. The positive effect traditionally attributed to privatizations is not confirmed. The importance of the effect is subordinated to some of the suggested variables.; Une lecture du processus de privatisation à travers la théorie de la …
Les activités de rééducation GAPP à l'école primaire : analyse du fonctionnement et évaluation des effets
1991
Alain Mingat : Die Umschulungsaktivitäten der GAPP (Gruppen zur psychopädagogischer Hilfe) in der Grundschule. Die GAPP wurden vor za. 20 Jahren geschaffen mit dem Zweck, die Schüler zu unterstützen, die vorübergehende Schwierigkeiten zur guten Eingliederung in die Schule aufweisen. Diese Einrichtung wurde bisher lediglich diskursiv analysiert. Der vorliegende Artikel zeigt, dass starke Unterschiede im Funktionieren der Dienstleistungen bestehen (Mittelzuweisung durch die Verwaltung, Umschulungspraxis, allgemein und zwischen den einzelnen GAPP-Einrichtungen) mit der Konsequenz, dass die Zulassungsentscheidungen sehr ungenau sind : das erleichtet nebenbei die Bewertung der Auswirkungen. Dies…
Évaluation de l'efficacité externe de la formation des agriculteurs
1997
Alain Mingat und Nelly Stephan, Bewertung der externen Effektivität landwirtschaftlicher Ausbildung. In diesem Beitrag soill die externe Effektivität der Ausbildung der Landwirte bewertet werden. Dabei soll festgestellt werden, ob besser ausgebildete Landwirte effizienter als weniger gut ausgebildete sind. Die durchgeführte Untersuchung erlaubte die Wirksamkeit der Ausbildung in zwei Phasen zu untersuchen : zum Zeitpunkt der Niederlassung in einem landwirtschaftlichen Betrieb, wo der Landwirt die Ausrichtung seines Betriebs festlegt, und während dieser Niederlassung, urn die Fähigkeit zur Führung dieses Betriebs zu bewerten. Auch wenn die Anhebung des technischen Ausbildungsniveaus ein wich…
Les aides-éducateurs à l'école primaire : entre polyvalence et spécialisation, quelle efficacité pédagogique ?
2001
This paper examines the situation of classroom assistants who were recruited three years ago in French schools. This research took place in 150 schools (academy of Burgundy) in which two age groups (8 and 10) were assessed both at the begining and the end of the school year. It concerned a large sample of classroom assistants (150) whose timetables have been collected to know precisely how their time is used in schools and how it may influence students achievement. First of all, the main results show that classroom assistants take part in a lot of varied activities, especially in academic fields. Secondly, those activities tend to have a positive impact on students achievement, particularly…
Efficacité interne de l'enseignement primaire aux pays de la Communauté Economique des Pays des Grands Lacs (CEPGL) : question approfondie sur le Rwa…
2011
This PhD study has been achieved with objective to carry out the level of internal efficiency of the primary education in the CEPGL countries and the progress reaches toward the education for all after the period of ethnic and armed conflicts. In addition, specifically for Rwanda, to underline the individual, families and school factors explanatory of the repetition and drop-out in the primary schools. The data of our analysis come from different reports of ministries, international organizations and publications of researchers. The analysis of the primary education inside CEPGL countries, by the indicators that document education supply and demand, show that, after the period of conflicts,…
Cost and Financing of Education and its Impact on Coverage and Quality of Services and Efficiency and Equity in Sub-Saharan African Countries
2007
07052; In this chapter, we take mostly an international comparative perspective limited to Sub-Saharan African countries. First, we analyse first the macro picture and the public finance dimension, analyzing the systemic choices made in the distribution of public resources across levels and types of education. Second, we move to unit cost estimates and the factors accounting for their level in a given country and to their variation across the different countries of the region. Finally, we examine the implication of the choices made in the financial dimension upon outcomes (coverage and quality of educationl services), birnging issues of efficiency and equity into the analysis.

Actes des XIXè journées de l'AES; International audience; Depuis la réforme de 1991, la formation initiale des enseignants du primaire en Tunisie dure deux années au cours desquelles les élèves-enseignants sont astreints à un régime d'internat. Le financement de la formation des maîtres est assuré par les fonds publics, d'importantes aides sont octroyées aux élèves-enseignants. Leurs performances pédagogiques sont satisfaisantes, mais l'insertion des diplômés commence à être plus difficile.
