Contexte. Au Québec, l'abandon scolaire représente un problème important en raison des conséquences que cela engendre ainsi que de sa prévalence relativement élevée, comparativement aux autres provinces canadiennes. Il est donc important d'étudier le phénomène, d'en comprendre les facteurs de protection et de vulnérabilité, afin permettre à une plus grande proportion d'élèves d'obtenir leur diplôme d'études secondaires. Objectif. Selon la littérature, un faible quotient intellectuel (QI) est un facteur de risque important du décrochage scolaire. Le but de cette étude est donc d'étudier l'effet modérateur de la relation élève-enseignant sur le lien entre le QI et le décrochage scolaire chez les adolescents au secondaire. Méthode. Les données proviennent de l'étude Stratégie d'Intervention Agir Autrement (SIAA), qui avait pour principal objectif d'évaluer l'effet de la mise en œuvre de la SIAA sur la réussite des élèves ainsi que de la capacité des écoles à leur offrir une éducation optimale. Lors de ce projet, une importante quantité d'informations a donc été mesurée selon un devis longitudinal prospectif. La collecte de données à été menée sur une période de sept ans auprès d'élèves de niveau secondaire faisant partie de deux cohortes distinctes. Ces derniers ont répondu aux protocoles d'entrevue une fois par année. D'une année à l'autre, les mêmes mesures, à quelques détails près, étaient colligées, à l'exception du QI qui n'a été mesuré qu'à la première année de chaque cohorte. À l'aide de ces données recueillies, des analyses de régression logistique ont été effectuées. Résultats. Les analyses permettent de confirmer que les variables prédictrices utilisées contribuent à prédire le décrochage scolaire. Cependant, les résultats suggèrent que les relations élève-enseignants ont un apport non significatif au modèle de prédiction. Conclusion. Ces deux variables ne modèrent donc pas le lien entre le QI et le décrochage scolaire dans cette étude., Context. In Quebec, dropping out of school is a major problem because it tend to lead to important consequences and for its higher prevalence in comparison with other Canadian provinces. It is therefore important to study the phenomenon, to understand the factors of protection and vulnerability in order to allow a greater proportion of students to obtain their secondary school diploma. Objective. According to previous studies, a low intelligence quotient (IQ) is an important risk factor of school dropout. The purpose of this study is to investigate the moderating effect of the student-teacher relationship on the relation between the IQ and the high school dropout for adolescents. Method. This project is a secondary analysis from the SIAA (Stratégie d'Intervention Agir Autrement) study who's main objective was to assess the impact of SIAA implementation on student achievement and the ability of schools to provide optimal education. During this project, a significant amount of information was measured according to a prospective longitudinal estimate. The data collection was conducted over a seven-year period with high school students in two distinct cohorts. Students responded to the interview protocols once a year. The same measures, with few minor differences, were compiled except for the IQ which was only measured the first year of each cohort. Using this data, logistic regression analyzes were performed. Results. The analysis confirm that the predictive variables used help in predicting school dropout. However, the results suggest that warm or conflicting student-teacher relationships have an insignificant contribution to the prediction model. Conclusion. These two variables do not moderate the link between IQ and school dropout in this study.

In this paper we analyse the location dynamics of French agriculture from 1990 to 2006. We apply this analysis for the main agricultural sectors at the department level. We show that spatial dynamics are mainly related to region and not to agricultural sectors. We show also that agglomeration effects may exist between departments and led to form clusters. The “Grand Ouest” French region is the unique area which benefits from a local positive dynamic for several sectors of production., Dans cet article nous analysons les dynamiques de localisation de la production agricole en France entre 1990 et 2006. L’analyse menée pour les principaux secteurs agricoles au niveau départemental montre que les dynamiques spatiales sont globalement régionales et que des effets d’agglomération existent entre les départements. Le Grand Ouest de la France est le seul espace qui bénéficie d’une dynamique locale positive dans plusieurs secteurs de production.

The formation of anomalies in the calcification of the shell in the flat oyster Ostrea edulis , is not a recent phenomenon. The authors used spat of oyster from France and Greece cultured in the Arosa Estuary, Galicia, Spain, through the punt or floating park system very spread in the Galician estuary. The calculation of different indices of condition show us that the formation of blisters increases the grade of the shell concavity and it does not affect the meat content of the oyster. The studies of crystallization in the calcareous layers that form the blisters, prove the "calcite", as the only type of crystal and the existence of disorder and disorientiation in the growing of the crystals., La formation d'anomalies dans la calcification des coquilles d'huîtres plates Ostrea edulis n'est pas un phénomène récent. Pour leur étude nous avons utilisé de jeunes huîtres originaires de France et Grèce, élevées dans la Ria de Arosa (Galice) à partir de radeaux flottants ou « bateas » très répandus dans cette région. Le calcul des indices de condition a démontré que la formation de chambres provoque un accroissement du degré de concavité de la coquille mais n'affecte pas le rendement en chair de l'huître. Les études de cristallisation du carbonate calcique dans les couches calcaires formant les chambres, démontrent que la calcite est le seul type cristallin et que la croissance des cristaux n'a plus d'orientation privilégiée.

Abstract The objective of this study was to search for polymorphisms in the coding region of the estrogen receptors 1 and 2 (ESR1 and ESR2 )and to analyze the effects of these variants and the well known intronic ESR1 Pvu II polymorphism on litter size in a Chinese-European pig line. We identified five silent single nucleotide polymorphisms (SNP) in the ESR1 cDNA: c.669T > C (exon 3), c.1227C > T (exon 5), c.1452C > T (exon 7), c.1665T > C and c.1755A > G (exon 8). One pair of these SNP (c.1665T > C and c.1755A > G) co-segregated in the analyzed line, and the SNP c.669T > C showed the same segregation pattern as the Pvu II polymorphism. These polymorphisms were tested in this study, although the c.1452C > T SNP within exon 7 was not analyzed due to its low informativeness. In the ESR2 cDNA, one missense SNP was found within exon 5, which caused an amino acid substitution in the coded protein: "c.949G > A (p.Val317Met)" and was tested on sow litter size. Information on 1622 litter records from 408 genotyped sows was analyzed to determine whether these SNP influenced the total number of piglets born (TNB) or the number of born alive (NBA). The polymorphisms ESR1: [Pvu II; c.669T > C], ESR1: [c.1665T > C; c.1755A > G] and ESR2: c.949G > A showed no statistically significant association with litter size. However, the ESR1: c.1227T allele was significantly associated with TNB. The additive substitution effect was estimated to be 0.40 piglets born per litter (P < 0.03), and no dominance effects were observed. This SNP could be useful in assisted selection for litter size in some pig lines, as a new genetic marker in linkage disequilibrium with the causative mutation.

Abstract Background The aim of this work was to study the effects on litter size of variants of the porcine genes RBP4, ESR1 and IGF2, currently used in genetic tests for different purposes. Moreover, we investigated a possible effect of the interaction between RBP4-MspI and ESR1-PvuII polymorphisms. The IGF2-intron3-G3072A polymorphism is actually used to select lean growth, but other possible effects of this polymorphism on reproductive traits need to be evaluated. Methods Detection of polymorphisms in the genomic and cDNA sequences of RBP4 gene was carried out. RBP4-MspI and IGF2-intron3-G3072A were genotyped in a hyperprolific Chinese-European line (Tai-Zumu) and three new RBP4 polymorphisms were genotyped in different pig breeds. A bivariate animal model was implemented in association analyses considering the number of piglets born alive at early (NBA12) and later parities (NBA3+ ) as different traits. A joint analysis of RBP4-MspI and ESR1-PvuII was performed to test their possible interaction. In the IGF2 analysis, paternal or maternal imprinting effects were also considered. Results Four different RBP4 haplotypes were detected (TGAC, GGAG, GAAG and GATG) in different pig breeds and wild boars. A significant interaction effect between RBP4-MspI and ESR1-PvuII polymorphisms of 0.61 ± 0.29 piglets was detected on NBA3+. The IGF2 analysis revealed a significant increase on NBA3+ of 0.74 ± 0.37 piglets for the paternally inherited allele A. Conclusions All the analyzed pig and wild boar populations shared one of the four detected RBP4 haplotypes. This suggests an ancestral origin of the quoted haplotype. The joint use of RBP4-MspI and ESR1-PvuII polymorphisms could be implemented to select for higher prolificacy in the Tai-Zumu line. In this population, the paternal allele IGF2-intron3-3072A increased litter size from the third parity. The non-additive effects on litter size reported here should be tested before implementation in other pig breeding schemes.
