Résumé : International audience
Seven male subjects volunteered to participate in an investigation of whether the diurnalincrease in core temperature influences the effects of pre-cooling or passivewarm-up on muscular power. Morning (07:00-09:00 h) and afternoon (17:00-19:00 h) evaluation of maximal power output during a cycling sprint was performed on different days in a control condition (room at 21.8 °C, 69% rh), after 30 min of pre-cooling in a cold bath (16 °C), or after 30 min of passivewarm-up in a hot bath (38 °C). Despite an equivalent increase from morning to afternoon in core temperature in all conditions (+0.4 °C, P < 0.05), power output displayed a diurnalincrease in control condition only. A local cooling or heating of the leg in a neutral environment blunted the diurnal variation in muscular power. Because pre-cooling decreases muscle power, force and velocity irrespective of time-of-day, athletes should strictly avoid any cooling before a sprint exercise. In summary, diurnal variation in muscle power output seems to be more influenced by muscle rather than core temperature.

Résumé : International audience
La partie française de l’île de Saint-Martin est une collectivité d’Outre-mer et se caractérise par une situation de multilinguisme (français-anglais-espagnol-créole). Ce contexte pose la question des stratégies pédagogiques et didactiques in situ. Les lycées de la partie française s’efforcent d’appliquer les réformes de l’Hexagone dont celle du « Nouveau Lycée » de la rentrée 2010, en particulier l’accompagnement personnalisé. Cette étude a pour but d’étudier comment les langues en présence participent aux interactions au cours des séances d’accompagnement personnalisé et en quoi l’alternance codique peut favoriser une dynamique pédagogique et relationnelle plus spécifique à Saint-Martin. Pour ce faire, nous prendrons l’exemple de deux corpus réalisés à partir d’une observation des échanges entre des groupes. L’observation du rôle des alternances codiques, révélateurs identitaires des pratiques langagières plurilingues, s’avère capitale pour comprendre les ressorts d’une interaction entre apprenants confrontés à la réalisation d’une tâche donnée par un enseignant.

Résumé : International audience
To investigate thermal response, hydration behaviour and performance over flatwater kayaking races in tropical conditions (36.8°C and 68 % rh). Five internationally-ranked subjects participated in the 2012 Surfski Ocean Racing World Cup in Guadeloupe to the “Ze Caribbean Race 2012” [i.e., a 35-km downwind race]. Core temperature (T°C) and heart rate (HR) were measured using portable telemetry units whereas water intake was deduced from backpacks absorption. The kayakers were asked to rate both their comfort sensation and thermal sensation on a scale before and after the race. The performance was related to an increase in T°C, high HR and low water intake (WI); and (2) high values of final T°C were related to high pre T°C and greater increases in T°C being obtained with low pre T°C and (3) WI being related to high pre T°C. The present study demonstrated that the fastest kayakers were those able to paddle at the highest intensities, increasing their T°C and drinking little water without any interference from thermal sensations. Water intake was positively related to pre-race T°C, which reinforces the importance of beginning surfski races with a low T°C. This study demonstrated that well-trained kayakers drinking ad libitum were able to anticipate their intensity/heat storage ratio to prevent heat illness and severe dehydration and maintain high performance.

Résumé : The physiological ageing, the chronic conditions and the psycho-social environment are source of vulnerability to the old subject. These factors impact on the oral pathologies while the oral affections can deteriorate them on the contrary and lead the patient in the spiral of the decompensation. The clinical examination has to consist of a global approach of the eldely person, what confers it a specific character. Within the framework of this article, we propose a methodology of diagnostic survey bringing to light the necessity of interdisciplinary collaboration between the medical participants
Le vieillissement physiologique, les pathologies chroniques et l’environnement psychosocial sont source de vulnérabilité chez le sujet âgé. Ces facteurs impactent les pathologies bucco-dentaires alors que les affections orales peuvent à l’inverse les aggraver et conduire le patient dans la spirale de la décompensation. L’examen clinique doit consister en une approche globale de la personne âgée, ce qui lui confère son caractère spécifique.

Résumé : Aim The aim of the present study was to examine whether listening to music during warming-up might influence short-term maximal performance (STMP), cognitive anxiety, self-confidence, and enjoyment during Ramadan, and whether these affects might predict STMP. Methods Nine male physical education students (age: 21 ± 1.1 years; height: 1.8 ± 0.04 m; body mass: 83 ± 5 kg) volunteered to participate in the present study. A within-subjects design consisted of four experimental sessions: Two sessions occurred one week before Ramadan and two others took place during Ramadan. They were scheduled at 5 p.m. and were conducted as follows: After a 10-minute warm-up either with or without listening to music, each participant performed a 5-m multiple shuttle run test, after which he was asked to answer items intended to assess his affective state during the experimental task. Results Our findings revealed that STMP was lower during Ramadan than before Ramadan in the no-music condition. Additionally, it was found that STMP was higher in the music condition than in the no-music condition during Ramadan, and that STMP measured before Ramadan did not differ from that measured during Ramadan in the music condition. Regarding affects, the findings revealed that enjoyment was lower during Ramadan than before Ramadan in the music condition, and that cognitive anxiety was lower in the music condition than in the no-music condition before Ramadan. Self-confidence was not influenced by the experimental conditions. Conclusion This study showed that listening to music during warming-up not only would be beneficial for STMP in Ramadan fasters, but also would counteract the negative effects of Ramadan observance on STMP.

Résumé : International audience
Coral reef fisheries support the development of local and national economies and are the basis of important cultural practices and worldviews. Transitioning economies, human development, and environmental stress can harm this livelihood. Here we focus on a transitioning social-ecological system as a case study (Moorea, French Polynesia). We review fishing practices and three decades of effort and landing estimates with the broader goal of informing management. Fishery activities in Moorea are quite challenging to quantify because of the diversity of gears used, the lack of centralized access points or markets, the high participation rates of the population in the fishery, and the overlapping cultural and economic motivations to catch fish. Compounding this challenging diversity, we lack a basic understanding of the complex interplay between the cultural, subsistence, and commercial use of Moorea's reefs. In Moorea, we found an order of magnitude gap between estimates of fishery yield produced by catch monitoring methods (2 t km −2 ∼ year −1) and estimates produced using consumption or participatory socioeconomic consumer surveys (∼24 t km −2 year −1). Several lines of evidence suggest reef resources may be overexploited and stakeholders have a diversity of opinions as to whether trends in the stocks are a cause for concern. The reefs, however, remain ecologically resilient. The relative health of the reef is striking given the socioeconomic context. Moorea has a relatively high population density, a modern economic system linked into global flows of trade and travel, and the fishery has little remaining traditional or customary management. Other islands in the Pacific in similar contexts in Polynesia such as Hawaii, that continue to develop economically, may have small-scale fisheries that increasingly resemble Moorea. Therefore, understanding Moorea's reef fisheries may provide insight into their future.

Résumé : International audience
The natural river water certified reference material SLRS-5 (NRC-CNRC) was routinely analysed in this study for major and trace elements by ten French laboratories. Most of the measurements were made using ICP-MS. Because no certified values are assigned by NRC-CNRC for silicon and 35 trace element concentrations (rare earth elements, Ag, B, Bi, Cs, Ga, Ge, Li, Nb, P, Rb, Rh, Re, S, Sc, Sn, Th, Ti, Tl, W, Y and Zr), or for isotopic ratios, we provide a compilation of the concentrations and related uncertainties obtained by the participating laboratories. Strontium isotopic ratios are also given. Le matériau de référence certifié d'eau de rivière naturelle SLRS-5 (NRC-CNRC) est analysé régulièrement comme contrôle qualité par dix laboratoires français étudiant les éléments majeurs et en trace dans les solutions naturelles.

Résumé : International audience
BACKGROUND: Environmental exposures, including dietary contaminants, may influence the developing immune system. This study assesses the association between maternal pre-parturition consumption of seafood and wheeze, eczema, and food allergy in preschool children. Fish and shellfish were studied separately as they differ according to their levels of omega-3 polyunsaturated fatty acids (which have anti-allergic properties) and their levels of contaminants. METHODS: The PELAGIE cohort included 3421 women recruited at the beginning of pregnancy. Maternal fish and shellfish intake was measured at inclusion by a food frequency questionnaire. Wheeze, eczema, and food allergy were evaluated by a questionnaire completed by the mother when the child was 2 years old (n = 1500). Examination of the associations between seafood intake and outcomes took major confounders into account. Complementary sensitivity analyses with multiple imputation enabled us to handle missing data, due mostly to attrition. RESULTS: Moderate maternal pre-parturition fish intake (1 to 4 times a month) was, at borderline significance, associated with a lower risk of wheeze (adjusted OR = 0.69 (0.45-1.05)) before age 2, compared with low intake (< once/month). This result was not, however, consistent: after multiple imputation, the adjusted OR was 0.86 (0.63-1.17). Shellfish intake at least once a month was associated with a higher risk of food allergy before age 2 (adjusted OR = 1.62 (1.11-2.37)) compared to low or no intake (< once/month). Multiple imputation confirmed this association (adjusted OR = 1.52 (1.05-2.21)). CONCLUSIONS: This study suggests that maternal pre-parturition shellfish consumption may increase the risk of food allergy. Further large-scale epidemiologic studies are needed to corroborate these results, identify the contaminants or components of shellfish responsible for the effects observed, determine the persistence of the associations seen at age 2, and investigate potential associations with health effects observable at later ages, such as allergic asthma.

Résumé : International audience
Introduction: The aims of this literature review were to characterize the communications presented during six Association for Research on Intervention in Sport (ARIS) French-speaking congresses from 2000 to 2010 and to compare the research trends between French and English research traditions. The definition of pedagogy is close to the notion of intervention and attempts to study, in an interacting or isolated way, three key components – the educator (professor, coach, teacher's educator), the participants (students, children, adults) and the curriculum/knowledge in specific contexts. The theoretical framework is centred on the social construction of the scientific knowledge. Method: All the communications of the six ARIS congresses (n ¼ 836), reflecting the multiple facets of educational research were analysed. The quantitative treatment of the data, with the assistance of Sphinx software, consisted of univariate (frequencies, percentages) and bi-variate (chi-square statistic) analyses to identify possible significant relations between variables such as the congress, country and sex of author(s), institution, and so on. Findings: The results highlight the commonalties and differences between French and English research about intervention/pedagogy. We notice the continuing expansion of the field of intervention/pedagogy in the Francophone and the Anglophone worlds. But the low participation of the practitioners shows how intricate it is to move educational research closer to everyday practice. The results show that the contexts studied within ARIS are mainly school physical education and teacher's education, then coaching and other contexts. The majority of studies are centred on one component of pedagogy, but rarely on the interactions between the educators and the participants. The Francophone research is essentially descriptive and heuristic, using mostly qualitative methods (interviews and observations). This orientation of Francophone studies towards heuristic research seems to contrast with Anglophone research, even though qualitative research has recently come to dominate. Conclusion: The ARIS researchers have a common object of study (intervention/ pedagogy), share the same ideas and aims, learn how to do it better as they interact regularly and develop a shared repertoire of knowledge, theories and methods. We see here signs of an undeniable wealth of knowledge and the combination of different theories and methods leading to a better understanding of educational phenomena.

Résumé : International audience
These authors contributed equally to this work. Abstract. Human behaviors are increasingly recognized to play a key role in the spread of infectious diseases. Although a set of social and cognitive determinants has been consistently found to affect the adoption of health protective behaviors aiming to control and prevent a variety of infections, little is currently known about the ecological drivers of these behaviors in epidemic settings. In this article, we took advantage of the outbreak of chikungunya, a reemerging mosquito-borne disease, that occurred in French Guiana in 2014–15 to test empirically the assumption proposed by Zielinski-Gutierrez and Hayden that the proximity of the disease and perceptions of the natural environment may considerably shape public response to an emerging health threat. To achieve this, a cross-sectional survey was conducted among high school students of the region (N = 1462) at an early stage of the epidemic. Surprisingly, spatial analysis of the collected data leads to counterintuitive results as the participants who lived in the most affected area expressed less concern about the disease and practiced preventive behaviors less frequently than did other participants. These paradoxical results may be attributed to the possible activation of risk denial processes which have previously been observed in the risk perception literature, and described by several social and psychological defensiveness theories.

Résumé : International audience
The parasports movement is marked, in France and since the 1980s, by a diversification of practices, notably with the gradual development of physical nature activities (Marcellini and Villoing, 2014). The access to natural spaces (mountainous, maritime, aerial) has become possible through technological progress and an always growing yearning for disabled people to access these spaces which are reputed as being inaccessible. Off-Road Wheelchair (ORWC), which started in France in 1991, is an example of the practices which are born from the initiative of enthusiasts who, after an accident, 'mess around in their workshop' with sporting equipment in order to rediscover their former practice. The pioneers of ORWC, to whom we gave voice (2 life history interviews) in this work, found in this practice a way to reclaim their former sensations in a mountainous milieu, but also a more touristic activity through expeditions to foreign countries. This activity was able to develop thanks to a collaboration between these 'enthusiasts', the 'handymen', local federal and political protagonists, and finally some industrialists. The aim of this work is to present conditions of institutionalization and 'sportivization' of ORWC (Guay, 1993) in France, seemingly turning it nowadays into a true tool of social participation.
Le mouvement handisport connaît, en France, depuis les années 1980, une diversification de ses pratiques, notamment avec l'arrivée progressive des activités physiques de pleine nature (Marcellini et Villoing, 2014). L'accès aux espaces naturels (montagneux, maritimes, aériens) est aujourd'hui devenu possible grâce aux progrès technologiques, et à une aspiration de plus en plus grande des personnes handicapées à accéder à des espaces réputés inaccessibles. La pratique du fauteuil tout terrain (FTT), apparue en France en 1991, est un exemple de pratiques nées de l'initiatives de passionnés qui, après un accident, bricolent 'au fond de leur garage' du matériel sportif afin de retrouver une pratique d'avant. Les pionniers du FTT, à qui nous avons donné la parole (2 entretiens d'histoire de vie) dans ce travail, ont trouvé dans cette pratique un moyen de retrouver des sensations passées en milieu montagnard mais également une activité touristique via des expéditions dans des pays étrangers. Cette activité va se développer grâce à la collaboration entre ces 'passionnés', ces 'bricoleurs', des acteurs fédéraux et politiques locaux, puis des industriels. Ce travail a pour objet de présenter les conditions d'institutionnalisation et de 'sportivisation' (Guay, 1993) du FTT en France qui semble être devenu aujourd'hui un véritable outil de participation sociale.

Résumé : International audience
BACKGROUND: Women of reproductive age can be exposed to endocrine-disrupting chemicals (EDCs) at work, and exposure to EDCs in pregnancy may affect fetal growth. OBJECTIVES: We assessed whether maternal occupational exposure to EDCs during pregnancy as classified by application of a job exposure matrix was associated with birth weight, term low birth weight (LBW), length of gestation, and preterm delivery. METHODS: Using individual participant data from 133,957 mother-child pairs in 13 European cohorts spanning births from 1994 through 2011, we linked maternal job titles with exposure to 10 EDC groups as assessed through a job exposure matrix. For each group, we combined the two levels of exposure categories (possible and probable) and compared birth outcomes with the unexposed group (exposure unlikely). We performed meta-analyses of cohort-specific estimates. RESULTS: Eleven percent of pregnant women were classified as exposed to EDCs at work during pregnancy, based on job title. Classification of exposure to one or more EDC group was associated with an increased risk of term LBW [odds ratio (OR) = 1.25; 95% CI: 1.04, 1.49], as were most specific EDC groups; this association was consistent across cohorts. Further, the risk increased with increasing number of EDC groups (OR = 2.11; 95% CI: 1.10, 4.06 for exposure to four or more EDC groups). There were few associations (p < 0.05) with the other outcomes; women holding job titles classified as exposed to bisphenol A or brominated flame retardants were at higher risk for longer length of gestation. CONCLUSION: Results from our large population-based birth cohort design indicate that employment during pregnancy in occupations classified as possibly or probably exposed to EDCs was associated with an increased risk of term LBW.

Résumé : International audience
Résumé : La prise en compte du plurilinguisme et des langues des élèves dans le système éducatif français est un véritable enjeu sociétal auquel l’école est confrontée. Entre les langues vivantes régionales, étrangères et celles issues de l’immigration, que fait concrètement l’école pour prendre en considération la diversité linguistique des élèves et des contextes d’enseignement ? Entre un enseignement conduit exclusivement dans une langue, des espaces spécifiques octroyées à certaines langues et des approches dites plurielles (Candelier, 2008), l’école propose différents dispositifs et conceptions de gestion du plurilinguisme, tels que le CASNAV (Centre Académique pour la Scolarisation des enfants Allophones Nouvellement Arrivés et des enfants issus de familles itinérantes et de Voyageurs), les cours de langues vivantes étrangères et régionales, les classes bilingues ou les sections européennes pour ne citer que ceux-là. Dans le contexte éducatif actuel où les différents acteurs (enseignants, inspecteurs, élèves, parents) oscillent entre plusieurs idéologies linguistiques allant du monolinguisme imposé au plurilinguisme, de l’égalité à l’inégalité des langues, du maintien de la diversité linguistique à sa disparition (Armand, 2016), nous présentons deux expérimentations auxquelles nous avons participé. Le premier concerne le dispositif de classes bilingues français-créole mis en place à partir de 2012 à l’école primaire en Guadeloupe. Le second dispositif est une recherche-action-formation menée en 2014 avec les enseignants des classes bilingues sur la co-construction de démarches portfolio contextualisées. Ces deux expérimentations tentent d’articuler l’utilisation des langues et la prise en compte du bi-plurilinguisme dans le but d’atteindre les différents objectifs nationaux fixés par les programmes scolaires en vigueur. En nous appuyons sur ces deux expériences, nous proposons des pistes de réflexion visant une approche didactique contextuelle du plurilinguisme en éducation et en formation. Cette dernière s’appuie, d’une part, sur trois principes en lien avec les classes bilingues : un contrat de communication de type linguistique, une trifocalisation de l’alternance codique et une rhétorique polylectale (Anciaux, 2016), et d’autre part, sur des diverses activités autour des biographies langagières et du rapport aux langues développés dans le cadre de démarches portfolio plurilingues.Références bibliographiques : Anciaux, F.

Résumé : International audience
Objective Large-scale prospective studies do not support an association between neuroticism and extroversion with cancer incidence. However, research on other personality constructs is inconclusive. This longitudinal study examined the associations between four personality measures, Type 1, "suppressed emotional expression"; Type 5, "rational/antiemotional"; hostility; and Type A with cancer incidence. Methods Personality measures were available for 13,768 members in the GAZEL cohort study (baseline assessment in 1993). Follow-up for diagnoses of primary cancers was obtained from January 1, 1994 to December 31, 2009. Associations between personality and cancer incidence were evaluated using Cox proportional hazards analyses and adjusted for potential confounders. Results During a median follow-up of 16.0 years (range, 9 days-16 years), 1139 participants were diagnosed as having a primary cancer. The mean duration between baseline and cancer diagnosis was 9.3 years. Type 1 personality was associated with a decreased risk of breast cancer (hazard ratio per standard deviation = 0.81, 95% confidence interval = 0.68-0.97, p = .02). Type 5 personality was not associated with prostate, breast, colorectal, or smoking-related cancers, but was associated with other cancers (hazard ratio per standard deviation = 1.17, 95% confidence interval = 1.04-1.31, p = .01). Hostility was associated with an increased risk of smoking-related cancers, which was explained by smoking habits, and Type A was not associated with any of the cancer endpoints. Conclusions Several personality measures were prospectively associated with the incidence of selected cancers. These links may warrant further epidemiological studies and investigations about potential biobehavioral mechanisms.

OBJECTIVE: The aim was to examine the relationship between physical activity pattern and dietary profile. Although some clustering of the variables related to these major determinants of cardiovascular risk has been demonstrated, they have not been extensively studied together. PARTICIPANTS, DESIGN, AND SETTING: Two hundred two female university students from the main Guadeloupe (French West Indies) campus participated. They self-administered a validated Food Frequency Questionnaire and the 1-yr recall Modifiable Activity Questionnaire. Principal-component analysis was performed on the scores and the variables related to the physical activity pattern and dietary profile. RESULTS: A model including 10 variables explained 84.9% of the total variance. The physical activity pattern was not associated with the dietary profile, apart from fruit intake. The physical activity level was homogeneously low (median 1.58, first and last quartile cutoffs 1.54 and 1.66, respectively). There was no correlation between the physical activity level and the Food Frequency Questionnaire score (r=-.005). CONCLUSIONS: The absence of a strong relationship between the food and physical activity profiles is interpreted as a possible reflection of a dysregulation of the quality of food intake in this population with a sedentary lifestyle.

Résumé : International audience
Based on both experimental and clinical data, tamoxifen has been proposed to have cardiovascular benefits, although the mechanism(s) contributing to that protective effect are still poorly understood. In vitro experiments demonstrated that tamoxifen elicits its transcriptional effect through estrogen receptor (ER) α, but other targets can participate in its actions. However, although tamoxifen selectively activates the activating function (AF)-1 of ERα, we recently showed that this ERα subfunction is dispensable for the atheroprotective action of 17β-estradiol (E2), the main ligand of ERs. The goal of the present work is to determine to which extent ERα and its AF-1 mediate the vasculoprotective action of tamoxifen. Our data confirm that tamoxifen exerts an atheroprotective action on low density lipoprotein receptor (LDL-r(-/-)) female mice, but, in contrast to E2, it fails to accelerate reendothelialization after carotid electric injury. Tamoxifen and E2 elicit differences in gene expression profiles in the mouse aorta. Finally, the atheroprotective action of tamoxifen is abrogated in ERα(-/-)LDL-r(-/-) mice and in LDL-r(-/-) mice selectively deficient in ERαAF-1 (ERαAF-1(0/0)LDL-r(-/-)). Our results demonstrate, for the first time to our knowledge, that tamoxifen mediates its actions in vivo through the selective activation of ERαAF-1, which is sufficient to prevent atheroma, but not to accelerate endothelial healing.
