Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates
2012
Marine N<sub>2</sub> fixing microorganisms, termed diazotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen (N<sub>2</sub>) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic …
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…
L'apprentissage/enseignement de la morphologie écrite du nombre en français
1999
In written French forms play an essential role. Numerous morphological marks have no correspondence in oral French. This is the case of plural flexions : -s for the plural of nouns and adjectives and -nt for verbs at the third person of indicative present. Earlier research showed that on the one hand the interpretation of these marks precedes their production and that this nominal flexion proceeding appears earlier and more correctly than adjectival flexion proceeding and verbal flexion (-nt). On the other hand, overgeneralizations were tracked down thanks to this research work : faultly use of flexions especially nominal flexions attributed to verbs (ils timbres). But in these investigatio…
Éducation primaire et croissance économique en Afrique subsaharienne : les conditions d'une relation efficace
1995
This article is looking at the causes of the low effectiveness of educational investment in Subsaharan Africa, both at the micro level (effect on labour productivity), and at the macro level (effect on the rate of economic growth). Several recent empirical studies have shown that education impact is systematically weaker in this region than in the rest of the world, and even sometimes negative, as in the case of agricultural productivity. Two series of causes may explain this lack of impact : first, inappropriate economic policies at the macro level which hamper the role of education, either through negative incentives structures, or because of the absence of provision of associated factors…
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,…
Les scolarités de la maternelle au lycée. Etapes et processus dans la production des inégalités sociales
1993
Marie Duru-Bellat, Jean-Pierre Jarousse, Alain Mingat : Die Schullaufbahnen von der Vorschule bis zum Gymnasium. Etappen und Prozesse in der Entstehung der sozialen Ungleichheit. Die Daten der Schuldemographie zeigen wichtige soziale Unterscheidungen beim Zugang zu identifizierten Schullaufbahnebenen wie Abitur oder Hochschule. Zwar ist dièse transversale Perspektive nützlich, sie ist jedoch unzureichend, um festzulegen, nach welchem "Kalender" und durch welche Mechanismen diese Unterscheidungen nach und nach entstehen. Dieser Artikel möchte die verschiedenen Rollen jeder dieser Unterrichtsebenen bewerten und dabei unterscheiden, was auf soziale Erfolgsunterschiede zuruckzufiihren ist, und …

2006
This work deals about the impacts both on supply and demand of education emerging from socio-political instability and trouble, the Sub Saharan geographical context.

Then, by a historical and socio-political step, the study in the evolution of the school since its creation in the Central Africa case shows that multiple factors impacted within time duration the development of education. Lastly, the analysis of the consequences of the disorders encountered in the since the beginning of the Nineties reveals…
