Carbon storage in soils by ancient and modern wheat varieties
2022
Les émissions anthropiques de gaz à effet de serre sont le principal moteur du changement climatique. Le plan Climat, issu de la COP 21 tenue à Paris en 2015, vise à atteindre la neutralité carbone à l'horizon 2050. Pour atteindre cette neutralité carbone, les gaz à effet de serre doivent d'abord être stabilisés, puis fortement réduits au cours du siècle prochain. Dans cette dynamique, l'initiative « 4 pour 1000 » fixe comme objectif d'atteindre un taux de croissance annuel du stock de carbone dans les sols de 0,4% par an. Ce stockage additionnel devrait compenser les émissions de CO2 dans l'atmosphère liée aux activités humaines. Les sols agricoles sont identifiés comme un compartiment de …

School environment, what effects on "individual" aspirations? The case of post-secondary education"
2007
The object of this study is to analyze differences in aspirations and choice of course of study at the outset of higher education. More particularly it aims to determine if the "individual" choices, which have an impact on the construction of educational inequalities, depend on school environment. Since the diversified character of school environment is an established fact in France, the first part of this work, based on a review of the sociology of education literature, draws attention to contextual dimensions as possible factors influencing educational and vocational aspirations. This question, which has remained unexplored at this level of the educational system in France, is dealt with …

De quelques difficultés à cumuler ses savoirs sur les phénomènes éducatifs : l'exemple de la démocratisation de l'enseignement

The stake here is to boost the scientific character of results in educational research, and therefore its legitimacy and its influence upon educational policies. The authors stress the importance of the historical context of data, the leading part of conceptualization, so that the structural changes of schooling may be grasped, and also the impact of technical measures upon factual knowledge. Finally, the issue of data, a difficult one in that field like in other ones, is illustrated by the analysis of the relation between "ZEP" (…
Reproduction behaviors : permanencies and changes : for a contextual and dynamic approach of the fertility
2015
Current levels of African fertility are, for most observers, the expression of a continuation of traditional values of ancestral essence. For those observers, the traditional values continue to determine reproductive behavior, despite the economic, political and social changes. Based on the case of the Republic of Congo, dynamic and contextual analysis of these behaviors, reveal that these are rather clear break from the current level of fertility; they suggest significant unmet need for birth control. It is possible that a Malthusian reflex develops gradually, which does not exclude the need for children, contrary to some theories. These behaviors are characterized by profound changes resu…
Augmented context based on prediction for efficient knowledge reuse of business knowledge in design
