Description : Qu'arrive-t-il lorsque une population s'empare du musée, se l'approprie et en fait un espace de rencontre, de débat, de partage ? L'idée d'un musée plus proche des populations s'est développée en France et dans le monde à partir des années 1970, sous l'appellation éco-musée,musée-communautaire. Parmi ses objectifs : replacer l'homme au centre du musée, renforcer son appartenance au territoire et permettre aux habitants de devenir acteur de la préservation de leur patrimoine dans un contexte de mutation rapide des modes de vie. C'est à ce musée-participatif que l'atelier sera consacré à travers plusieurs exemples guyanais et brésiliens. Comment construire un musée participatif ? Quelle médiation utiliser ? Comment susciter l'adhésion de la population locale ? Et, une fois mise en place, comment utiliser le musée ?

Résumé : International audience
The purpose of this study was to examine self-efficacy and self-esteem as predictors of claimed and behavioral self-handicapping, and to compare the relationship between behavioral and claimed self-handicaps and athletic performance. A total of 31 basketball players participated in the study. Claimed self-handicaps were significantly negatively correlated with self-esteem whereas behavioral self-handicapping was significantly negatively correlated with self-efficacy. Performance was negatively correlated with behavioral self-handicapping, but was not correlated with claimed self-handicapping. These findings reinforce the conceptual distinction between claimed and behavioral self-handicaps by demonstrating that the two strategies are indeed related to different factors and that they have different consequences for performance.

Résumé : International audience
The way faults control upward fluid flow in nonmagmatic hydrothermal systems in extensional context is still unclear. In the Eastern Pyrénées, an alignment of twenty-nine hot springs (29 ∘ C to 73 ∘ C), along the normal Têt fault, offers the opportunity to study this process. Using an integrated multiscale geological approach including mapping, remote sensing, and macro-and microscopic analyses of fault zones, we show that emergence is always located in crystalline rocks at gneiss-metasediments contacts, mostly in the Têt fault footwall. The hot springs distribution is related to high topographic reliefs, which are associated with fault throw and segmentation. In more detail, emergence localizes either (1) in brittle fault damage zones at the intersection between the Têt fault and subsidiary faults or (2) in ductile faults where dissolution cavities are observed along foliations, allowing juxtaposition of metasediments. Using these observations and 2D simple numerical simulation, we propose a hydrogeological model of upward hydrothermal flow. Meteoric fluids, infiltrated at high elevation in the fault footwall relief, get warmer at depth because of the geothermal gradient. Topography-related hydraulic gradient and buoyancy forces cause hot fluid rise along permeability anisotropies associated with lithological juxtapositions, fracture, and fault zone compositions.

Résumé : International audience
The purpose of the present experiment was to examine whether the use of self-handicapping strategies influences participants' anxiety levels before athletic performance. Seventy-one competitive basketball players participated in the study. A repeated measures design was used, such that state cognitive and somatic anxiety intensity and direction were measured before and after participants were given the opportunity to self-handicap. Overall, participants reported their cognitive anxiety to be more facilitating after they had the opportunity to self-handicap. Thus, participants who were given the opportunity to self-handicap (i.e., use claimed and behavioral self-handicaps), reported greater increases in perceptions of cog-nitive anxiety as facilitating their performance. This study shows the importance of looking at anxiety direction, and not just anxiety intensity, when examining self-handicapping's effects on anxiety. Implications for sport psychologists are proposed.

Résumé : International audience
Objectives: The purpose of the present study was to examine the mediational role of self-confidence and anxiety in the relationship between self-esteem and claimed self-handicapping in an achievement context. Design: To test this mediational role, the three-step procedure advocated by Baron and Kenny (1986) was used. Method: After hearing and reading about specific conditions of performing that were intended to favor invoking excuses for future poor performance, 68 competitive basketball players completed measures of self-esteem, anxiety (cognitive and somatic), self-confidence, and claimed self-handicapping. Then, they warmed-up and carried out a basketball task. Results: Self-esteem negatively predicted cognitive anxiety and positively predicted self-confidence. In turn, self-confidence negatively predicted claimed self-handicapping and mediated the relationship between self-esteem and claimed self-handicapping. Cognitive and somatic anxieties did not mediate the relationship between self-esteem and claimed self-handicapping. Together, these results suggest that individuals with low self-esteem use more claimed self-handicaps because they have lower self-confidence. Conclusion: These findings shed light on the psychological processes that lead people with low self-esteem to use strategies of claimed self-handicaps.

Résumé : International audience
The aim of the present study was to determine whether the use of claimed and behavioural self-handicaps and theircorrelates differed across experimentally manipulated motivational climates. Fifty-six competitive basketball playersparticipated in the study. A crossover design was used, such that all participants completed the experimental task (i.e., atest of basketball skill) in both mastery and performance climates. Analyses of variance showed that claimed self-handicapswere used more in the performance than the mastery condition but only for the men. In addition, greater behavioral self-handicapping occurred in the performance than the mastery climate. Contrary to expectation, neither type of self-handicapwas related to performance on the basketball task in either climate. These findings reinforce the conceptual distinctionbetween claimed and behavioural self-handicaps and suggest that individual and environmental factors may differentiallyinfluence each type of handicap.

Résumé : International audience
The way faults control upward fluid flow in extensive hydrothermal systems without an abnormal heat source such as volcanic or plutonic activity is still unclear. In the Eastern Pyrénées, an alignment of 29 hot springs (from 29 • C to 73 • C) along the Têt normal Fault offers the opportunity to study this process. Using an integrated multi-scale geological approach including mapping, remote sensing, macro and microscopic analyses of fault zones, we show that hot springs locate close to high topographic reliefs related to fault throw and segmentation. Emergences are always in crystalline rocks at gneiss-metasediments contacts, mostly in the Têt Fault footwall. In more details, they localize either (1) in brittle fault damage zones at the intersection between the Têt Fault and subsidiary faults, and (2) into hercynian ductile faults where dissolution cavities run along shear zones. Using these observations and 2D preliminary numerical simulations, we propose a hydrogeological model of upward hydrothermal flow. Meteoric fluids infiltrate at high altitude in the fault footwall relief where they acquire temperature because of the geothermal gradient. Hydraulic gradient and buoyancy forces allow them to upflow along fault-related permeability anisotropies. The identification and prioritization of the features controlling this kind of system have important implications for geothermal exploration and for the understanding of fluid-flow into the brittle Earth's crust in general.

Central Africa hosts the world's second largest tropical forest after the Amazonian basin. However, as compared to its Amazonian counterpart, the Central Africa forests receive much less rain (∼1500 mm/year in mean spread over two rainy seasons in March-May and September-November, and two dry seasons). They also experience a slower deforestation rate, so that the main threat for the next decades might come from climate variations. Nonetheless, their response to the annual cycle of solar radiation and rainfall/clouds is still poorly known. Analysing high resolution remote sensing data of Enhanced Vegetation Index, rainfall, cloudiness, and solar radiation for a target region located between 0 and 5°N and 12–19°E, we explore the climatic drivers of the forests greenness mean annual cycle. Three main points emerge; first, the diurnal cycle is a key-scale for understanding the mean annual cycles of rainfall and incoming solar radiation at surface, then how climate shapes the greenness mean annual evolution; second, neither the two dry seasons nor the two rainy seasons resemble each other in terms of cloud cover, solar radiation and rainfall, and their links with greenness levels; third, whereas the first rainy season (March-May) appears optimal for greenness especially because of favorable light conditions, water availability is the main controlling factor during the main dry season and at the start of the first vegetative season (February). Regarding the little dry season (mid-June-mid-August) and the second rainy season (September-October), light availability might be the main limiting factor. These findings pave the way for further studies of the climate interannual variability and change impacts on the Central Africa forests, taking into account time-scale interactions.
