Social process of adaptation to environmental changes: How eastern african societies intervene between crops and climate

2014

Abstract Studies on climate change can only be conducted on a long time scale, and observing how societies adapt their sowing practices to climate variability is challenging and costly. As an alternative, a space and time substitution design was used, changes in space corresponding to that induced in time by environmental change. On the eastern slope of Mount Kenya, the Tharaka community, originating from the lowlands (750 m), moved up to the midlands (950 m) with their lowland-adapted resources, whereas the Mwimbi, originating from wetter upland (1100 m), moved down to the midlands with their highland-adapted genetic resources. A weather station was installed at 950 and 1100 m, and a logis…

GeneSys-Beet: A model of the effects of cropping systems on gene flow between sugar beet and weed beet

2008

A weedy form of the genus Beta, i.e. Beta vulgaris ssp. vulgaris (hence ''weed beet'') frequently found in sugar beet is impossible to eliminate with herbicides because of its genetic proximity to the crop. It is presumed to be the progeny of accidental hybrids between sugar beet (ssp. vulgaris) and wild beet (ssp. maritima), or of sugar beet varieties sensitive to vernalization and sown early in years with late cold spells. In this context, genetically modified (GM) sugar beet varieties tolerant to non-selective herbicides would be interesting to manage weed beet. However, because of the proximity of the weed to the crop, it is highly probable that the herbicide-tolerance transgene would b…

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…

La réussite en éducation musicale : des facteurs individuels aux facteurs contextuels

2007

This study aim to improve knowledge about individual and contextual factors of success in music education during elementary level's first year. There are three main subjects : acquisitions' social inequalities, teacher-effect and children' interest about in class musical activities. Two musical tests (one at the beginning of the year, another at the end) were administrated to 1184 students living in Burgondy. Questionnaries completed by various actors (teachers and students) gave a lot of data. Data were analysed with multivariate models. Our results demonstrated that 1°) musical practices develop abilities and explain social origin's effect on musical acquisitions at the beginning of the y…
