Résumé : This thesis falls within the scope of social and human geography and more exactly of« disability studies ». Understanding the disability like a « social object », the thesis analyzes the societal consideration of disabled people in non-urbanized areas with a high issue of touristic, recreational and patrimonial development. In the first place, it's the recent construction of disability as a social object that is discussed by reminding the history of the societal consideration of the disabled person in our occidental world. The French model and his fundamental rule of global accessibility for ail the domains of the social life are explained and the « Nature and Disability » thematic is more precisely analyzed as a development of an active living ideal for people who are in a disability situation. Secondly, the thesis develops this thematic on the particular field of the Reunion Island and tries to answer to a question which is both simple and complicated: « Today, how we live with a disability on the Reunion Island? ». ln a last time and on the basis of this study of the disability inside a Reunion Island society with accelerated transformations, the thesis specifies the current tendencies with the emergence of new public policies for the welcome of disabled people on natural and touristic areas of the island. To conclude and referring to an original survey, the thesis suggests some tools of evaluation and decision-making aids to these areas.
Cette thèse s'inscrit dans le champ de la géographie humaine et sociale et plus précisément dans celui des « disability studies ». En positionnant le handicap comme une « figure du social », la thèse analyse la prise en compte sociétale des personnes à mobilité réduite (PMR) dans des environnements non urbanisés, à très fort enjeu de développement touristique, récréatif et patrimonial. Dans un premier temps, c'est la construction récente du handicap en tant que figure du social qui est abordée, en rappelant l'historique de la considération de la personne handicapée dans nos sociétés occidentales. Le modèle français et son principe fondamental d'accessibilité généralisée à tous les domaines de la vie sociale sont détaillés et la thématique « Nature et Handicap » est analysée plus précisément, en tant que développement d'un idéal de vie active pour les personnes en situation de handicap. Dans un second temps, la thèse développe cette thématique sur le terrain particulier de l'Île de La Réunion et tente de répondre à une question à la fois simple et complexe : « comment vit-on avec une déficience aujourd'hui à La Réunion ? ». Dans un dernier temps et sur la base de cette analyse du handicap au sein d'une société réunionnaise aux mutations accélérées, la thèse précise les tendances actuelles avec l'apparition de nouvelles politiques publiques d'accueil des PMR dans les espaces naturels et touristiques de l'île. S'appuyant sur une enquête originale, la thèse propose enfin des outils d'évaluation et d'aide à la décision spécifiques à ces espaces.

Résumé : International audience
This study aims to describe current risk management practices and policies across the world in relation to personal exposures from devices emitting radiofrequency fields, environmental exposures from fixed installations and exposures in the work environment. Data from 86 countries representing all WHO regions were collected through a survey. The majority of countries (76.8 %) had set exposure limits for mobile devices, almost all (90.7 %) had set public exposure limits for fixed installations and 76.5 % had specified exposure limits for personnel in occupational settings. A number of other policies had been implemented at the national level, ranging from information provisions on how to reduce personal exposures and restrictions of usage for certain populations, such as children or pregnant women to prevention of access around base stations. This study suggests that countries with higher mobile subscriptions tend to have set radiofrequency exposure limits for mobile devices and to have provisions on exposure measurements about fixed installations.

Résumé : Pour la bibliothèque La Pérouse, l’année 2010 a confirmé les mutations profondes qui bouleversent les bibliothèques et centres de documentation depuis plusieurs années. Le formidable progrès que représente l’accès à la documentation en ligne a modifié les comportements des chercheurs et des étudiants, contraignant les bibliothèques et centres de documentation à s’adapter. En 2010, la BLP s’est donc attachée à : - Enrayer la désertification de notre site, pourtant si agréable et confortable, en proposant de nouveaux usages sur place, plus ouverts et plus conviviaux, - Tenir compte des nouveaux comportements en proposant de nouveaux services dédiés à chacun de nos publics, s’appuyant sur une enquête de besoins et sur une analyse de type marketing, - Amorcer une reconversion des personnels pour mieux prendre en charge ces nouveaux services. Le développement de l’open access est une chance pour la BLP qui a su développer très tôt son archive ouverte Archimer, dont une nouvelle version a vu le jour en 2010. (...)

Résumé : P>The distribution of the archaeal communities in deep subseafloor sediments [0-36 m below the seafloor (mbsf)] from the New Caledonia and Fairway Basins was investigated using DNA- and RNA-derived 16S rRNA clone libraries, functional genes and denaturing gradient gel electrophoresis (DGGE). A new method, Co-Migration DGGE (CM-DGGE), was developed to access selectively the active archaeal diversity. Prokaryotic cell abundances at the open-ocean sites were on average similar to 3.5 times lower than at a site under terrestrial influence. The sediment surface archaeal community (0-1.5 mbsf) was characterized by active Marine Group 1 (MG-1) Archaea that co-occurred with ammonia monooxygenase gene (amoA) sequences affiliated to a group of uncultured sedimentary Crenarchaeota. However, the anoxic subsurface methane-poor sediments (below 1.5 mbsf) were dominated by less active archaeal communities, such as the Thermoplasmatales, Marine Benthic Group D and other lineages probably involved in the methane cycle (Methanosarcinales, ANME-2 and DSAG/MBG-B). Moreover, the archaeal diversity of some sediment layers was restricted to only one lineage (Uncultured Euryarchaeota, DHVE6, MBG-B, MG-1 and SAGMEG). Sequences forming two clusters within the Thermococcales order were also present in these cold subseafloor sediments, suggesting that these uncultured putative thermophilic archaeal communities might have originated from a different environment. This study shows a transition between surface and subsurface sediment archaeal communities.

Résumé : Plant leaf litter generally decomposes faster as a group of different species than when individual species decompose alone, but underlyingmechanisms of these diversity effects remain poorly understood. Because resource C : N: P stoichiometry (i.e. the ratios of these key elements) exhibits strong control on consumers, we supposed that stoichiometric dissimilarity of litter mixtures (i.e. the divergence in C : N: P ratios among species) improves resource complementarity to decomposers leading to faster mixture decomposition. We tested this hypothesis with: (i) a wide range of leaf litter mixtures of neotropical tree species varying in C : N: P dissimilarity, and (ii) a nutrient addition experiment (C, N and P) to create stoichiometric similarity. Litter mixtures decomposed in the field using two different types of litterbags allowing or preventing access to soil fauna. Litter mixture mass loss was higher than expected from species decomposing singly, especially in presence of soil fauna. With fauna, synergistic litter mixture effects increased with increasing stoichiometric dissimilarity of litter mixtures and this positive relationship disappeared with fertilizer addition. Our results indicate that litter stoichiometric dissimilarity drives mixture effects via the nutritional requirements of soil fauna. Incorporating ecological stoichiometry in biodiversity research allows refinement of the underlying mechanisms of how changing biodiversity affects ecosystem functioning.

Résumé : Tout en étant une des régions les plus pauvres du Pérou, le sud andin est la destination touristique nationale par excellence où se trouve le sanctuaire archéologique de Machu Picchu, un des sites du patrimoine mondial les plus prisés au monde. Le boom du développement touristique des années 1990 à rapidement transformé la région de Cuzco en une destination écotouristique et de tourisme culturel. Cette étude présente le développement du tourisme dans la région en général, ainsi que les effets sur quelques communautés spécifiques s’étant intégrées au système touristique international grâce au développement du chemin de l’inca, une randonnée de quatre jours servant de porte d’entrée à Machu Picchu. Les hommes des communautés paysannes des hauts plateaux andins avoisinant Ollantaytambo ont été sollicités pour transporter l’équipement nécessaire au service des randonneurs étrangers. Ces habitants représentaient une main d’œuvre accessible, abordable, voire exploitable, capable physiquement de transporter des poids lourds en haute altitude. Aujourd’hui, la Fédération des Porteurs Daniel Estrada est composée de 6200 porteurs provenant de différentes communautés de la vallée. Essentiellement quechuas, ces communautés rurales marginalisés survivent sur des terres arides ; leur niveau d’éducation ne dépasse souvent pas le primaire ; les villages ne disposent pas d’eau potable, de services d’égouts, d’électricité, de téléphone, d’accès à des services de santé ; les habitations sont faites d’adobe. Étant donné la vulnérabilité de ces populations, l’intégration à un système offrant de nouvelles possibilités de revenus s’avérait souhaitable, malgré les conditions d’emploi déplorables.
While one of the poorest regions of Peru, the Andean south is a national tourist destination and the site of the archaeological sanctuary and one of the most popular sites in the world, Machu Picchu. The boom of tourism development in the 1990s quickly transformed the Cuzco region to an ecotourism and cultural tourism destination. This paper presents the development of tourism in the region in general, as well as the effects for some communities as they are integrated into the international tourism system through the development of the Inca Trail, a four-day hike which leads to Machu Picchu. Men in the peasant communities in the Andean highlands surrounding Ollantaytambo are asked to carry the equipment needed by foreign hikers during the ascent. These people represent an available and affordable workforce, physically capable of carrying heavy weight at high altitudes. Today, the Daniel Estrada Federation of Carriers is composed of 6200 carriers from different communities in the valley. Mainly Quechua, these marginalized rural populations survive in an arid environment; their education often does not exceed the primary level; the villages lack drinking water, sewage services, electricity, telephones, and access to health services; and the houses are made of adobe. Given the vulnerability of these populations, the integration of a system offering new revenue opportunities proved desirable, in spite of the deplorable employment conditions.

Résumé : International audience
Background: Two antifibrotic drugs, pirfenidone and nintedanib, are approved by the European Medicines Agency and the US Food and Drug Administration for the treatment of idiopathic pulmonary fibrosis (IPF). In this analysis, treatment patterns of European patients with IPF were investigated to understand antifibrotic prescribing and identify unmet needs in IPF treatment practice. Methods: Between February and March 2016, respiratory physicians from France, Germany, Italy, Spain, and the UK participated in an online questionnaire designed to collect information on IPF treatment patterns in patients under their care. Patients were categorized as treated (received approved antifibrotics) or untreated (did not receive approved antifibrotics, but may have received other unapproved therapies). Classification of IPF diagnosis (confirmed/suspected) and severity ('mild'/'moderate'/'severe') for each patient was based on the individual physician's report. Patients' perspectives were not recorded in this study. Results: In total, 290 physicians responded to the questionnaire. Overall, 54% of patients with IPF did not receive treatment with an approved antifibrotic. More patients had a confirmed IPF diagnosis in the treated (84%) versus the untreated (51%) population. Of patients with a confirmed diagnosis, 40% did not receive treatment. The treated population was younger than the untreated population (67 vs 70 years, respectively; p = 0.01), with more frequent multidisciplinary team evaluation (83% vs 57%, respectively; p = 0.01). A higher proportion of untreated patients had forced vital capacity > 80% at diagnosis versus treated patients. Of patients with 'mild' IPF, 71% did not receive an approved antifibrotic versus 41% and 60% of patients with 'moderate' and 'severe' IPF, respectively. Conclusions: Despite the availability of antifibrotic therapies, many European patients with confirmed IPF do not receive approved antifibrotic treatment. Importantly, there appears to be a reluctance to treat patients with 'mild' or 'stable' disease, and instead adopt a 'watch and wait' approach. More education is required to address diagnostic uncertainty, poor understanding of IPF and its treatments, and issues of treatment access. There is a need to increase physician awareness of the benefits associated with antifibrotic treatment across the spectrum of IPF severity.

Résumé : Plant litter diversity effects on decomposition rates are frequently reported, but with a strong bias towards temperate ecosystems. Altered decomposition and nutrient recycling with changing litter diversity may be particularly important in tree species-rich tropical rainforests on nutrient-poor soils. Using 28 different mixtures of leaf litter from 16 Amazonian rainforest tree species, we tested the hypothesis that litter mixture effects on decomposition increase with increasing functional litter diversity. Litter mixtures and all single litter species were exposed in the field for 9 months using custom-made microcosms with soil fauna access. In order to test the hypothesis that the long-term presence of tree species contributing to the litter mixtures increases mixture effects on decomposition, microcosms were installed in a plantation at sites including the respective tree species composition and in a nearby natural forest where these tree species are absent. We found that mixture decomposition deviated from predictions based on single species, with predominantly synergistic effects. Functional litter diversity, defined as either richness, evenness, or divergence based on a wide range of chemical traits, did not explain the observed litter mixture effects. However, synergistic effects in litter mixtures increased with the long-term presence of tree species contributing to these mixtures as the home field advantage hypothesis assumes. Our data suggest that complementarity effects on mixed litter decomposition may emerge through long-term interactions between aboveground and belowground biota.

Résumé : The Atlantic coast of Martinique shows the typical characteristics of the tropical regions with a coral facies, and especially: a) a wide variety of sedentary animal species, especially coral fishes, of smaller sizes and numbers, thus forming smaller populations than those living under other latitudes ; b) the presence, between the shore and the reef barrier, of a shallow strip of soft bottoms, without any natural shelter, well protected, but with difficult access for off-shore species, and with a poor fauna. It is the major explanation for the weakness of the performances on this restricted continental shelf where, in addition, the fishing effort keeps growing. The complex relief of the reef makes the use of the trawl nets impossible and very difficult that of filtering nets, like bottom gillnets, which proved difficult to handle on the reef areas, as observed through this campaign. For these reasons, the Atlantic coast of Martinique is bound to an artisanal exploitation, whose expansion is very limited by the natural ecologic conditions. [...]
La côte atlantique martiniquaise présente les caractéristiques typiques des régions tropicales à faciès corallien et essentiellement: a) une grande variété d'espèces animales sédentaires, et en particulier de poissons récifaux, de tailles généralement réduites et de faible abondance numérique, constituant des populations bien moins denses que celles qui existent sous d'autres latitudes; b) la présence, entre le rivage et la barrière corallienne, d'une bande peu profonde de fonds doux, dépourvue d'abris naturels, bien protégée, mais peu accessible aux espèces du large et où le règne animal est pauvre. C'est là l'explication majeure de la faiblesse des rendements obtenus sur ce plateau continental restreint sur lequel, en outre, l'effort de pêche ne cesse d'augmenter. Le relief complexe du récif y rend impossible l'utilisation des arts traînants et très difficile celle des engins filtrants comme les filets calés, dont cette campagne nous a montré le peu de maniabilité sur les secteurs coralliens. Pour ces raisons, la zone littorale atlantique martiniquaise est vouée exclusivement à une exploitation de type artisanal, dont les possibilités d'expansion sont très limitées par les conditions écologiques naturelles. D'après l'examen des données recueillies, l'état des stocks halieutiques littoraux, tant en poissons qu'en crustacés semble encore assez satisfaisant dans l'ensemble. Cependant, il faut souligner le fait que l'accroissement de l'effort et du nombre des pêcheurs « occasionnels », et l'exploitation en général encore très anarchique des ressources, auxquels on assiste à l'heure actuelle en dépit de la législation existante, risquent, si l'on n'y prend garde, de conduire à brève échéance à une surexploitation des fonds côtiers. Il est facile, pour les professionnels, d'éviter l'appauvrissement qui menace ces lieux de pêche, s'ils prennent conscience, dès à présent, de la nécessité d'appliquer spontanément et sans contraintes un certain nombre de mesures de protection indispensables. Enfin, de premières observations nous laissent supposer que les conditions de milieu, existant au-delà de la barrière corallienne, sont favorables à la prolifération d'une faune benthique, mais surtout pélagique, abondante et de bonne qualité. C'est donc vers le large, ou, dans un premier temps, le semi-large qu'il convient d'orienter les actions en vue d'assurer l'essor de la pêche atlantique martiniquaise.

Résumé : The Nephrops trawl fishery is one of the most important fisheries in the Bay of Biscay. The fishery management essentially relies on conservation measures, a total at I owed catch (TAC) for Nephrops together with a mini mum landing size (MLS) and minimum trawl mesh size (70 mm stretched mesh). These measures have failed to prevent high discard levels of many species that characterize the fishery. Nephrops trawlers thus discard about half of their Nephrops catches in numbers (a third in weight) of which only 30% survive. Nephrops discards mainly occur in younger Nephrops age groups below the MLS. This is a waste for the already overexploited Nephrops stock as well as for the fleet. Based on a bio-economic simulation model, the paper analyses the consequences of several scenarios of improving Nephrops selectivity. The potential impacts of these scenarios on Nephrops biomass, landings, discards and economic indicators (e.g. rent) are examined and a cost-benefit analysis of each scenario is carried out. We show that a better exploitation pattern would benefit fisheries that have high level of discards. Reducing non-commercial Nephrops discards leads to positive net present values of rent with better value realized from the production potential and limited short-term losses for the fishing units. By taking account of the economic dynamics of increasing effort however, we show that selectivity measures are insufficient. Regulating access to the fishery is also required to ensure the sustainability of the fishery and a better exploitation of the production potential. (C) 2008 Elsevier B.V. All rights reserved.

Résumé : International audience
OBJECTIVES: Semen composition is influenced by HIV-1 infection, yet the impact of semen components on HIV infection of primary target cells has only been studied in samples from HIV-uninfected donors. DESIGN: We compared the effect of seminal plasma from chronically HIV-infected (SP+) versus uninfected donors (SP-) on HIV-1 infection of PBMCs and CD4+T cells. METHODS: Primary cells were infected with HIV-1 in the presence of SP+ or SP- and analyzed for infection level, metabolic activity, HIV receptor expression, proliferation and activation. SP+ and SP- were compared for infection-enhancing peptides, cytokines and prostaglandin E2 levels. RESULTS: SP- efficiently enhanced HIV-1 R5 infection of CD4+ T cells, whereas SP+ enhancing activity was significantly reduced. RANTES concentrations were elevated in SP+ relative to SP-, while the concentrations of infectivity-enhancing peptides (SEVI, SEM1, SEM2) were similar. CCR5 membrane expression levels were reduced on CD4+T cells shortly post-exposure to SP+ compared with SP- and correlated to R5-tropic HIV-1 infection levels, and CCR5 ligands' concentrations in semen. SP+ and SP- displayed similar enhancing activity on PBMC infection by X4-tropic HIV-1. Addition/depletion of RANTES from seminal plasmas modulated their effect on PBMC infection by R5-tropic HIV-1. CONCLUSIONS: Semen from HIV-infected donors exhibit a significantly reduced enhancing potential on CD4+ T cell infection by R5-tropic HIV-1 when compared with semen from uninfected donors. Our data indicate that elevated seminal concentrations of RANTES in HIV+ men can influence the ability of semen to enhance infection.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives 4.0 License, where it is permissible to download and share the work provided it is properly cited.

Résumé : International audience
Semantic web standards, tools, ontologies and related technologies have considerably matured in the recent years. Nowadays, accessing a wide catalogue of biological, social, environmental, and ecological data sources helps stakeholders working on biodiversity to answer their complex questions. Will the real time access to web resources effectively support the definition of strategies to conserve and manage biodiversity? How might semantic web technologies help us to handle the complex and heterogeneous big data related to biodiversity? The workshop aims to identify the key challenges faced by the bioinformatics community, discuss potential solutions and identify the opportunities emerging from the trans-disciplinary interactions between Plant Science and Informatics experts. Therefore, we expect the bioinformatics experts to explain how they apply semantic web standards and tools to their scientific topic, from biology, agriculture, agro-ecology, genomics, environmental studies, to social sciences, citizen sciences. Research papers presenting various aspects of semantic web technologies applied to biodiversity data, ranging from position papers to implemented systems descriptions and their evaluation, will be selected. We are particularly interested in the use of the semantic technologies to design and develop systems that supports research on agricultural and wild biodiversity conservation and management for food security. Examples may include strategies for resilience to climate change pressures, sustainability of productive ecosystems, ecosystems services monitoring or territories management, rather than systems supporting only research on climate patterns or soil erosion.

Résumé : International audience
French Guiana is a South American French territory, where HIV prevalence consistently exceeds 1% in the adult population. In the only correctional facility, HIV prevalence fluctuates at around 4%.
After describing the population of HIV-positive inmates, we aimed to evaluate mortality after release from the correctional facility, and to identify its predictive factors.
Outside North American settings, data on treatment outcome and vital status of HIV-positive former inmates are scarce. There were no data in French Guiana. Filling this gap represents a basis for potential improvements.
All HIV-infected adults released from an incarceration of 30 days or more, between 2007 and 2013, were enrolled in a retrospective cohort study. Mortality was described over time, one to seven years following release, using Kaplan-Meier estimates. Factors associated with mortality were identified through a non-parametric survival regression model.
147 former inmates were included. The male to female ratio was 4.4. The median age was 37.3 years. The majority were migrants, 25.8% were homeless, 70.1% suffered from substance abuse, with 34.0% of crack-cocaine users. On admission, 78.1% had an early HIV-stage infection (CDC-stage A), with a median CD4 count of 397.5/mm3, 34.0% had one comorbidity, mainly hypertension. Upon release, 50.3% were on ART. Reasons for not being treated were not fulfilling the criteria for 74.6%, and refusing for 15.1%. Before release, 84.5% of the patients on ART had a viral load≤200cp/ml. After release, 8.2% of the cohort had died, with a crude incidence of 33.8/1000 person-years. All recorded deaths were males, with an incidence of 42.2/1000 person-years. Comparing with the age-specific mortality rates for males in French Guiana, the standardized mortality ratio was 14.8. In multivariate analysis, factors associated with death were age and CD4 count before release.
Despite access to ART while incarcerated, with good virological outcome, the post-release mortality was very high for males, almost 15 times what is observed in the general male population living in French Guiana, after age standardization. Access to ART in correctional facilities may be a necessary, but not sufficient condition to protect male inmates from death after release.

Résumé : Exploitation of Trochus niloticus is important for Pacific islanders. The shell yields valuable mother of pearl of wich 2.000 tons were exported from New Caledonia in 1978. Knowledge of the exploitable stock requires a good estimate of the surface area occupied by this gastropod which colonises dead coral reefs. Because trochus environments in New Caledonia are very extensive and access is difficult, synoptic methods of estimation are called for. High resolution remote sensing appears to be a particularly suitable method. Simulation of images to be obtained from the French SPOT satellite was carried out in New Caledonia in decemlber 1983. This paper deals with the method used to process the digital high resolution images that will be produced by SPOT. Results are presented as thematic maps of the main reef environment types, with their respective surface areas. Among hard reef bottom covers, the trochus environment was finely analysed and areas identified were compared with ground truth observations and with areial photograph interpretation. The potential usefulness of high resolution SPOT images is confirmed for thematic mapping and evaluation of shallow living reef resources.

Résumé : There is increasing evidence from previous studies, and from fishers' observations, that coastal dolphins use fishing nets as an easily accessible feeding source, damaging or depredating fish caught in the nets. This study investigates the impact of dolphin depredation on artisanal trammelnets by analysing the catch composition of 614 artisanal fishing operations in the Bonifacio Strait Natural Reserve (France). Common bottlenose dolphins (Tursiops truncatus) attacked, on average, 12.4% of the nets and damaged 8.3% of the catch. However, attacked nets were characterized by statistically significantly higher catch per unit effort than unattacked ones. Catch composition also differed significantly after dolphin attacks; bentho-pelagic fish were more represented and reef-associated fish less represented. Our results suggest that (i) dolphins are attracted by high fish densities in the fishing area and/or nets, and (ii) their attacks induce specific fish-avoidance behaviour, according to the fish position in the water column. Although dolphins depredate a small part of the catch, damage to nets, not yet assessed in this area, could weaken the benefits that reserves can provide to artisanal fisheries.

Résumé : En Haïti, rien ne semble être planifié et pensé sur le long terme, raison sans doute pour laquelle l’entrepreneuriat ne joue pas un rôle prépondérant dans le développement de l’économie du pays (Financial Times, 2015). Cette vision sur le court terme qui est celle de la majorité de la population -à savoir les pauvres- n’est cependant pas une vérité absolue puisque le groupe largement minoritaire de la population, les riches ou encore l’élite économique, compte des entrepreneurs au sens des pays riches, c'est-à-dire des personnes ayant une vision de l’entreprise sur le long terme avec pour perspective la croissance de l’entreprise et l’enrichissement personnel, parfois « saupoudré » ,ici et là, d’une touche sociale par rapport à la montée en puissance du phénomène Responsabilité Sociale des Entreprises (RSE). Ce numéro spécial sur l’entrepreneuriat en Haïti se veut force de propositions (pratiques) pour que l’entrepreneuriat ait droit de cité comme force motrice du développement d’Haïti. Si comme le dit l’entrepreneur Jerry Tardieu : investir et s’investir en Haïti est un acte de foi, que faire pour faire pour que l’entrepreneuriat soit un moteur de développement durable en Haïti ? Telle est la question centrale de ce numéro spécial. L’entrepreneuriat en Haïti a longtemps été marqué – notamment dans la partie formelle – par la dominance du commerce opéré pour une large part par des immigrés moyen-orientaux (Syriens, Libanais, etc.) et de grandes entreprises étatiques. L’économie haïtienne a entamé depuis les trois dernières décennies un élargissement de son entrepreneuriat à travers la privatisation des monopoles d’Etat et, récemment, se précise l’engouement des jeunes pour la création d’entreprises. Si pour certains analystes comme Lundahl (2010), l’entrepreneuriat communautaire a échoué en Haïti, il n’en demeure pas moins que la micro finance a connu un développement tel, qu’elle a démocratisé l’accès au financement et permis le développement d’une multitude de micro-entreprises (Paul, Daméus & Garrabé, 2011). In Haiti, nothing seems to be planned in advance. Everything seems to happen by chance, hence the reason why entrepreneurship is a heavy weight in the GDP of the country (Financial Times, 2015). This non strategic and short term vision of entrepreneurship in Haiti is peculiar to the vast majority of the population, that is to say the poor. However, this does not happen across the board as the rich (the minority of population) also called the ‘elite’ have a perception of entrepreneurship similar to developed countries where entrepreneurship is seen as a long term strategy with so called Corporate Social Responsibilities (CSR). This special issue about Haiti is to find practical solutions to ensure that entrepreneurship can play a major role in the economic development of the country. Jerry Tardieu, a Haitian entrepreneur, claimed that investing in Haiti is a proof of faith in the country’s potential. What can be done to turn entrepreneurship into a sustainable tool for the development of Haiti? This is the central research question of this special issue. For a while, leading entrepreneurs in Haiti were from the Middle East (Syria, Liban, etc) and public companies. However, over the last three years, entrepreneurs in Haiti have come from different backgrounds. Also, more and more young people are getting into entrepreneurship and many public companies have been privatised. Despite the fact that for some analyst’s entrepreneurship in Haiti has totally failed (Lundahl, 2010), the development of micro finance over the last few years has democratized access to funding, enabling development of a multitude of micro-enterprises (Paul & Dameus Garrabé, 2011) (Paul, Daméus & Garrabé, 2011). En Haití, nada parece estar planificado y pensado en el largo plazo, probablemente es la razón por la cual la iniciativa empresarial no está jugando un papel importante en el desarrollo de la economía (Financial Times, 2015). Esta visión a corto plazo es el de la mayoría de la población. Sin embargo, no es una verdad absoluta ya que el grupo de población en gran minoría, los ricos o la élite económica, los empresarios responsables de los efectos de los países ricos es decir, las personas con una visión de negocio a largo plazo con la perspectiva del crecimiento de la empresa y de enriquecimiento personal, aunque a veces 'salpicado aquí y allá de un toque social, en comparación con el aumento del fenómeno de la Responsabilidad Social Corporativa (RSC). Este número especial sobre el emprendimiento en Haití quiere suscitar propuestas (prácticas) para que la iniciativa empresarial llega a ser citada como una fuerza impulsora en el desarrollo de Haití. Si, como lo dice el empresario Jerry Tardieu, invertirse e invertir en Haití es un acto de fe, ¿que hacer para que el espíritu empresarial sea un motor para el desarrollo sostenible en Haití? Esta es la pregunta central de este número especial. Emprendimiento en Haití durante mucho tiempo ha sido etiquetado - sobre todo en la parte formal - por el predominio del comercio operado en gran parte por inmigrantes de Oriente Medio (Siria, Líbano, etc.) y las grandes empresas estatales. La economía haitiana ha comenzado las últimas tres décadas la expansión de la iniciativa empresarial a través de su privatización de los monopolios estatales y, desde hace poco, la moda de los jóvenes emprendedores. Aunque segun algunos analistas como Lundahl (2010), el emprendimiento comunitario no sucede Haití, el hecho es que las microfinanzas ha experimentado un desarrollo tal, se ha democratizado el acceso a la financiación, como permite el desarrollo de una multitud de microempresas (Paul & Dameus Garrabé, 2011).

Résumé : International audience
Off road wheelchair riding, a “ hiking boots” : body experience and identity reconfigurations. Feel sensations during the practice of nature sport is not new. However, a disabled person feels similar sensations to an abled person, through access to the mountain with an Off Road Wheelchair Riding (ORWC), is part of a normalization process. This activity appeared in France in the early 1990’s. It allows people who have lost all or part of their mobility, to be able to access to high mountains. The interviewees are quadriplegic and paraplegic after an accident. Their speeches reveal the body uses in ORWC for reliving the sensations in mountain environment. The reconquest of natural areas is the social limitations to overcome, to escape a negative social assignment of the disabled person, but also to regain a self-identity.
La question de l’expérience corporelle lors d’une pratique sportive de pleine nature est récurrente. Cependant, qu’une personne handicapée expérimente sensations similaires à un individu « valide », en accédant à la montagne en Fauteuil Tout Terrain (FFT), participe d’un processus de normalisation. Cette activité, apparue en France au début des années 1990, permet aux personnes qui ont perdu la totalité ou une partie de leur mobilité, d’accéder à la haute montagne. Les enquêtés, accidentés tétraplégiques ou paraplégiques, révèlent des usages du corps en FTT pour revivre des sensations en milieu montagnard. La reconquête des espaces naturels représente les limites sociales à surmonter permettant d’échapper à une assignation sociale négative de la personne handicapée, mais également de reconstituer une identité à soi.

Résumé : International audience
The diversity of chemicals used in hospitals (detergents-disinfectants, alcohol-based hand sanitizers, drugs, etc.) and recent developments in indoor air quality regulation of public access buildings require a better understanding of chemical risks in this particular environment. We developed a methodology for semi-quantitative chemical risk assessments in this environment to prioritize inhalation risks by sector and chemical. This methodology is based on a similar approach in the workplace that defines classes of exposures and of hazards. Their combination produces a risk matrix. Four criteria were used to determine the exposure classes: quantity and frequency of the chemical's use, volatility (vapor pressure), and the type of collective protective equipment associated with each area. The hazard class is also derived from four criteria: classification as carcinogenic, mutagenic, or toxic to reproduction, the existence of a toxicity reference value, occupational exposure limit values, and risk phrases (official risk descriptions, on labels, data sheets, etc). This methodology was tested in the Rennes University Hospital (Rennes, France) in five different hospital areas, with a specific survey undertaken to collect data about chemicals in each area. The results show the spatial specificity of chemical risks. Among the various sites analysed, the chemical risks of two require priority attention: the parasitology-mycology laboratory and patients' rooms. Because of their wide use in the hospital and the volatility of some of their components (alcohols), detergents-disinfectants contribute to increasing risk levels in all areas. The model is therefore discriminatory in terms of areas and substances.
