Analyse des pratiques de RSE des clubs sportifs professionnels français

Autrefois réservé à la grande entreprise, le concept de Responsabilité Sociétale des Entreprises (RSE) s'étend aujourd'hui à l'ensemble des organisations. Dans cette optique, cet article s'intéresse aux déterminants et aux modalités de mise en oeuvre des pratiques de RSE dans les clubs sportifs pro- fessionnels français. À partir d'un cadre d'analyse permettant d'associer les approches institutionnelles et stratégiques en matière de RSE, nous montrons la difficulté pour ces organisations « hybrides » de trouver un équilibre entre les logiques d'action qui les animent. Les résultats montrent que les quatre cas de clubs étudiés (de basket-ball et de football) exercent des pratiques de RSE revêtant surtout une forme cosmétique. L'émergence de nouvelles formes de RSE laisse pourtant entrevoir des pratiques plus intégrées à même de réduire la tension entre les logiques économiques et sociales de ces organisations.

Les symbioses industrielles : une nouvelle stratégie pour l'amélioration de l'utilisation des ressources matérielles et énergétiques par les activités économiques

RésuméCette thèse traite d'un domaine d'application de l'écologie industrielle, les symbioses industrielles, comme stratégie d'amélioration de la consommation des ressources matérielles et énergétiques et de la gestion des déchets par les activités économiques. Les symbioses industrielles cherchent à créer de nouvelles collaborations directement entre les acteurs économiques d'un territoire dans le but d'échanger de l'information, des matières premières et des déchets, et d'intensifier les mutualisations de services et d'infrastructures possibles entre entreprises voisines. Ces quatre types de collaboration sont représentés schématiquement dans la figure ci-dessous.Dans ce travail, la détection et la mise en oeuvre de symbioses industrielles sont abordées sous plusieurs angles. Les recherches réalisées concernent le développement de procédures de mise en oeuvre s'adressant aux collectivités publiques, aux institutions académiques et aux bureaux de conseil dans le domaine de l'environnement. Les objectifs des procédures sont de créer une dynamique de collaboration et de confiance entre les acteurs économiques et l'administration publique d'un territoire afin de détecter des symbioses industrielles potentielles. Ces procédures requièrent la gestion de grandes quantités d'informations relatives aux flux de matière et d'énergie.Un travail de terrain, réalisé sur les territoires du canton de Genève et de Lausanne Région et utilisé comme études de cas, a permis de mettre en évidence un grand nombre de symbioses industrielles qui existent déjà en Suisse romande. Plusieurs dizaines d'exemples ont été identifiés principalement dans lesdomaines de la gestion de l'eau, de l'énergie, des produits chimiques et des matériaux de construction. La législation suisse autoriserait cependant la concrétisation de nombreuses autres opportunités. Dans cette recherche, celles-ci sont évaluées techniquement, légalement, économiquement et environnementalement. La création d'un référentiel d'évaluation des opportunités permet de déterminer quelles sont les symbioses industrielles techniquement réalisables et pertinentes dans le contexte suisse et dans quels cas celles-ci représenteraient une réelle plus-value par rapport à l'utilisation actuelle de la ressource et aux filières existantes de collecte et de valorisation des déchets.Finalement, un logiciel, SymbioGIS, destiné à soutenir la détection et l'évaluation de symbioses industrielles potentielles a été développé. Il s'agit d'une interface web accessible pour de nombreux utilisateurs, couplée à une interface de systèmes d'information géographique. En plus de la détection de symbioses industrielles, plusieurs fonctionnalités sont proposées pour faciliter la prise en compte des flux de matière et d'énergie dans les problématiques liées à l'aménagement du territoire et au positionnement des activités économiques.En conclusion, cette recherche met en évidence la nécessité de rapprocher les institutions publiques en charge de la protection de l'environnement, de la promotion économique et de l'aménagement du territoire pour favoriser l'essor des symbioses industrielles comme stratégie pour la gestion des ressources matérielles et énergétiques. Elle propose des pistes pour intensifier les collaborations entre ces domaines et accélérer le partage des connaissances liées aux flux de matière et d'énergie et à leur cheminement au sein des activités économiques afin de rendre le système industriel existant en Suisse romande viable à long terme. Parallèlement, elle étudie les possibilités de transposer ces considérations et les procédures et outils développés dans le contexte économique et social de la région Asie-Pacifique, où se trouvent aujourd'hui de nombreuses activités de production.SummaryIndustrial symbioses: A new strategy for improving how economic activities use material and energy resourcesThis thesis focuses on one application of industrial ecology, industrial symbioses, as a strategy for improving how economic activities consume material and energy resources. Industrial symbioses seek to create new collaborations among economic players with the goal of exchanging information, raw materials, and waste directly among area businesses, and to step up the potential pooling of services and infrastructure among neighboring companies.The identification and implementation of industrial symbioses are studied from several angles. The research first examines the development of implementation procedures for government bodies, academic institutions, and environmental consulting services. The purpose of the procedures is to create a dynamic of collaboration and trust between the economic players and the public officials in a region in order to identify potential industrial symbioses. The procedures necessitate managing large amounts of information about material and energy flows.Fieldwork conducted in the canton of Geneva and the Lausanne region, and used as case studies for the research, highlights a great number of industrial symbioses that already exist in French-speaking Switzerland. Several dozen examples are identified, primarily in the areas of water management, energy, chemical products, and building materials; however, Swiss law would permit many others. The research evaluates these opportunities from a technical, legal, economic, and environmental standpoint. By developing an assessment framework it is possible to determine which industrial symbioses are technically feasible and pertinent in Switzerland, and under what circumstances they would represent real added value compared to the current use of the resource and to existing systems for collecting and reusing waste.Lastly, SymbioGIS software was developed to help identify and assess potential industrial symbioses. The program's Web-based interface can be accessed by multiple users and is coupled with an interface that provides geographic information. In addition to identifying industrial symbioses, several program functionalities make it easier to consider material and energy flows with regard to local development issues and siting economic activities.In conclusion, the research highlights the need to bring together public institutions charged with protecting the environment, promoting economic activity, and overseeing development in order to foster the expansion of industrial symbioses as a strategy for managing material and energy resources. It proposes solutions for stepping up collaboration among these players and accelerating the sharing of knowledge about material and energy flows and their paths within economic activities with the goal of making theexisting industrial system in French-speaking Switzerland viable long-term. Also examined were thepossibilities of transposing these considerations and the study's findings about Switzerland to the economic and social context of the Asia-Pacific region, where much production is now located.

Density of Sand Flies (Diptera: Psychodidae) in Domestic and Wild Animal Shelters in an Area of Visceral Leishmaniasis in the State of Rio Grande do Norte, Brazil

The objective of the present study was to determine the association of sand flies with the presence of domestic and wild animals in the peridomiciliary area. The sand flies were collected using direct aspiration and CDC light traps placed in animal shelters. The results suggest that different sand flies species have different behavioral characteristics in an apparent preference for animal baits and that Lutzomyia longipalpis and Lu. evandroi were the most eclectic species regarding their biotope choice. Lu. longipalpis showed a distinct preference for horses and Lu. evandroi for armadillos.

Contribution to the sand fly fauna (Diptera: Phlebotominae) of Rio Grande do Sul, Brazil and Leishmania (Viannia) infections

American cutaneous leishmaniasis (ACL) is endemic in the State of Rio Grande do Sul, Brazil. As reports of nearby hospitals suggest, the Parque Estadual do Turvo seems to serve as a source for the disease. During three months from November 1996 to February 1997 we collected, in this park, 2,228 sandflies (10 Lutzomyia species and 2 6species). We applied the polymerase chain reaction to 920 females which belong to the following species: Lutzomyia migonei, Lu. pessoai, Lu. fischeri, Lu. misionensis, Lu. lanei, Lu. neivai, Lu. shannoni, and Lu. monticola, in an attempt to verify natural infection by Leishmania (Viannia), the causative agent of ACL. Le. (Viannia) infections were demonstrated by DNA amplification from two Lu. pessoai and one Lu. misionensis female. Lu. pessoai have been found with leptomonas in the gut believed to be Le. (V.) braziliensis in other endemic areas of northeastern and southeastern Brazil. However, Lu. misionensis has never been found carrying a natural infection of Le. (Viannia).

A review of the ticks (Acari, Ixodida) of Brazil, their hosts and geographic distribution - 1. The State of Rio Grande do Sul, Southern Brazil

A review of the ticks (Acari, Ixodida) of the State of Rio Grande do Sul, southern Brazil, was completed as a step towards a definitive list (currently indicated as 12) of such species, their hosts and distribution. The ticks: Argas miniatus (poultry), Ixodes loricatus (opossums), Amblyomma aureolatum (dogs), A. calcaratum (anteaters), A. cooperi (capybaras), A. nodosum (anteaters), A. tigrinum (dogs) (Neotropical) and Rhipicephalus sanguineus (dogs) (introduced, cosmopolitan, Afrotropical) were confirmed as present, in addition to the predominant, Boophilus microplus (cattle) (introduced, pan-tropical, Oriental). Of the further 18 species thus far reported in the literature as present in the state, but unavailable for examination: only Ornithodoros brasiliensis (humans and their habitations) (Neotropical), Ixodes affinis (deer) (Nearctic/Neotropical) and I. auritulus (birds) (Nearctic/Neotropical/Afrotropical/ Australasian) are considered likely; 13 species would benefit from corroborative local data but the majority appear unlikely; reports of A. maculatum (Nearctic/Neotropical, but circum-Caribbean) are considered erroneous; the validity of A. fuscum is in doubt. The very recent, first known report of the tropical Anocentor nitens (horses)(Nearctic/Neotropical), but still apparent absence of the tropical A. cajennense (catholic) (Nearctic/Neotropical) and the sub-tropical/temperate Ixodes pararicinus (cattle) (Neotropical) in Rio Grande do Sul are important for considerations on their current biogeographical distribution and its dynamics in South America. The state has relatively long established, introduced ("exotic"), Old World tick species (B. microplus, R. sanguineus) that continue to represent significant pests and disease vectors to their traditional, introduced domestic animal hosts, cattle and urban dogs. There are also indigenous, New World ticks (A. miniatus, O. brasiliensis, A. aureolatum, A. nitens), as both long established and possibly newly locally introduced species in the state, that should be considered as potential and emergent pests and pathogen vectors to humans and their more recently acquired, introduced domestic animal hosts; rural poultry, dogs and horses.

Monitoring the domiciliary and peridomiciliary invasion process of Triatoma rubrovaria in the State of Rio Grande do Sul, Brazil

The presence of Triatoma rubrovaria in Brazil has only been confirmed in the States of Paraná and Rio Grande do Sul (RS), where it is found naturally infected with Trypanosoma cruzi. In the wild environment it occurs in rocky habitats and has an eclectic diet, feeding from cockroaches, reptiles and mammals. Data from the Chagas Disease Control Program obtained by the Fundação Nacional de Saúde, between 1975 and 1997, indicate a growing domiciliary and peridomiciliary invasion of T. rubrovaria in RS, where it has become the most frequently Triatominae species captured in this state since the control of Triatoma infestans. In order to monitor this process, we analyzed collection data derived from 22 years of control campaigns against T. infestans. Collection data for triatomines from domestic habitats show an inverse relationship, with high numbers of T. infestans and low numbers of T. rubrovaria during 1976-1987, compared to the following ten years, 1986-1997, when the number of T. infestans dropped drastically and that of T. rubrovaria increased. There are no consistent indications of intradomiciliary colonization by T. rubrovaria, since only low numbers of nymphs have been captured in the intradomiciliary ecotopes. Nevertheless, this species appears to have preadaptive characteristics for anthropic ecotopes, and should be kept under constant epidemiological surveillance.

Simulium spp. control program in Rio Grande do Sul, Brazil

Insects of the Simuliidae family have been the object of control in Rio Grande do Sul since the 70s. Their constant attacks became a social-economical problem as well as a problem of Public Health, with serious consequences to men and to the economy of the areas in which the insects develop. At first, the control was done with a chemical larvicide Themephos ABATE 500 E, but an imperfect measuring of outflow to determine the quantity of the product made Simulium spp. resistant to it. From 1983 on, following a study of a new method for the outflow measuring, we started to use a biological larvicide Bacillus thuringiensis serovar israelensis based. The biological control uses the new method in 36.4% of the state area, assisting about 3,500,000 inhabitants.

Nova espécie do complexo oliveirai (nova denominação para o complexo matogrossensis) (Hemiptera, Reduviidae, Triatominae) do estado do Rio Grande do Sul, Brasil

The authors describe a new species of Triatominae (Hemiptera, Reduviidae) from the State of Rio Grande do Sul, Brazil. The study was made with specimens captured in basaltic formations, at an average altitude of 750 m.o.s.l. The new species is included in the oliveirai complex together with other four species T. williami, T. matogrossensis, T. guazu and T. jurbergi). The new species was compared with the most similar one, T. oliveirai, from which the main differences are on the proportions of head, ante and postocular regions, the general color pattern and the male genitalia, specially on the median process of the pygophore, the support of phallosome, the vesica and the process of the endosome.
