    Sociologie des techniquesDu point de vue d’une sociologie de la connaissance, la recherche contemporaine en intelligence artificielle tire son originalitĂ© de l’intĂ©rĂȘt portĂ© Ă  la modĂ©lisation de la connaissance ordinaire, ce savoir engagĂ© dans la vie de tous les jours (ex. aller l’épicerie, prendre son petit dĂ©jeuner). Les entreprises Facebook ou Google, le fameux GAFAM ainsi que les services de musique et de vidĂ©os en ligne capturent et modĂ©lisent les faits et gestes du quidam afin de remettre les rĂ©sultats de leurs calculs en jeu dans cette mĂȘme vie courante. La recherche en IA porte Ă©galement sur la mise en forme de savoirs savants et professionnels tout comme durant les annĂ©es 1960 et 1970, mais cette thĂšse ne s’y intĂ©ressera pas. Dans le cadre d’une sociologie des sciences et des techniques, je me questionne sur ce que nous, en tant que civilisation occidentale, faisons du dĂ©veloppement technologique, du monde que nous construisons Ă  l’aide des diverses techniques. Ma prĂ©occupation ne porte pas sur les choix des objets privilĂ©giĂ©s par la recherche des laboratoires publics et privĂ©s, mais sur les usages, les dĂ©bouchĂ©s selon la question trĂšs gĂ©nĂ©rale : en quoi telle technique modifie-t-elle ou non notre façon de vivre ? Or, cette question relĂšve d’un exercice de prospective dans la mesure oĂč bien souvent nous ne possĂ©dons pas assez de recul sur ces techniques. Elle demeure malgrĂ© tout une prĂ©occupation d’arriĂšre-plan de mes questions de recherche. En effet, ces modĂšles d’apprentissage machine, trouveraient-ils leur place au sein d’une civilisation qui n’accorderait pas autant d’importance Ă  l’efficacitĂ©, Ă  la productivitĂ©, Ă  la rentabilitĂ©, Ă  la science ou encore au travail ? Aussi, viennent-ils entĂ©riner l’ordre Ă©tabli ou bien offrent-ils de nouvelles possibilitĂ©s d’existence ? Comprendre minimalement l’artefact d’un point de vue technique et saisir du point de vue de la sociologie la façon dont les chercheurs pensent leurs objets nous Ă©claire sur les catĂ©gories de pensĂ©es principales qui orientent ces usages et le cas Ă©chĂ©ant sur les Ă©ventuels effets sociĂ©taux. En l’occurrence, l’idĂ©e de modĂ©liser de nombreuses activitĂ©s de la vie quotidienne repose sur une reprĂ©sentation Ă  priori de celle-ci de la part de chercheurs localisĂ©s socialement par leur profession et plus gĂ©nĂ©ralement leurs relations sociales diverses. Quelle est cette reprĂ©sentation et comment est-elle opĂ©rationnalisĂ©e dans les modĂšles ? PosĂ©e autrement, de quels rapports au monde tĂ©moignent ingĂ©nieurs et informaticiens par l’intermĂ©diaire de leurs connaissances professionnelles, savantes et ordinaires ? Ainsi, dans cette thĂšse, mon travail se ramĂšne Ă  informer de la dimension sociale propre Ă  la technique Ă©tudiĂ©e. À partir d’entretiens auprĂšs de chercheurs en IA, la question de recherche est la suivante : quels sont les savoirs et raisonnements chez les chercheurs au fondement de l’élaboration des algorithmes relevant de l’intelligence artificielle contemporaine et qui construisent une reprĂ©sentation opĂ©ratoire particuliĂšre de la vie sociale ? ExprimĂ©e en terme sociologique, cette question devient : en quoi les modĂšles d'apprentissage sont-ils un nouveau « modĂšle concret de connaissance » pour les usagers et informaticiens selon le concept dĂ©veloppĂ© par le sociologue Gilles Houles ? Les modĂšles dits d’apprentissage sous-tendent une conception relationnelle de la constitution de la connaissance humaine et d’un rapport Ă  la rĂ©alitĂ© mĂ©diĂ© par l’action comme moyen d’actualisation de cette connaissance. RĂ©sumĂ© simplement, le concept sociologique de « modĂšle concret de connaissance » objective les deux modalitĂ©s d’existence de la vie humaine que nous retrouvons empiriquement sous deux concepts informatiques : symbolique (leur modĂšle mathĂ©matique) et l’action ou « l’agent informatique » ou « celui qui agit », que ce concept soit mobilisĂ© ou non par les chercheurs. En somme, ces modĂšles en relation les uns avec les autres et matĂ©rialisĂ©s dans les objets dits connectĂ©s ou « smart » (ex. tĂ©lĂ©phones, Ă©lectromĂ©nagers) forment un schĂ©ma opĂ©ratoire organisateur de la vie sociale. Ce cĂŽtĂ© opĂ©ratoire repose sur la position de « tiers mĂ©diateur » ou de « mĂ©moire sociale technicisĂ©e » dans les relations humains-humains via machines. Je m'appuierai sur le concept de mĂ©moire sociale et de morphologie sociale dĂ©veloppĂ©e par le sociologue Maurice Halbwachs. Autrement dit, ce rĂ©seau d’objets connectĂ©s et d’ĂȘtres humains se ramĂšne Ă  l’instauration d’un cadre cognitif collectif particulier, issu des reprĂ©sentations sociales de groupes professionnels prĂ©cis, mais mises en jeu dans la vie courante de tous, soit une institutionnalisation en cours. En effet, la diffusion et l’adoption des modĂšles dĂ©coulent d’un processus de reconnaissance publique de savoirs sous-jacents et dĂ©jĂ  institutionnalisĂ©s, pour l'essentiel, les mathĂ©matiques et l’ingĂ©nierie, le savoir implicite des « sciences de la gestion » et un savoir dit « scientifique » par les chercheurs. Plus prĂ©cisĂ©ment, le processus en cours consiste en l’institution d’ĂȘtres humains et de machines apprenantes en liens permanents via les objets connectĂ©s (« Internet of Things »). Au final, elle consiste en une mise en rĂ©seau des « rĂ©gularitĂ©s sociales » obtenues par classifications et rĂ©gressions effectuĂ©es par les dĂ©tenteurs des donnĂ©es. Je parlerai d'une « morphologie sociotechnique » ou d’une « configuration sociotechnique ». À la figure du robot polyvalent anthropomorphique censĂ© condenser toute la mise en pratique du savoir sur l’IA, se substitue celle de relations sociales informatisĂ©es comme lieux du maintien des liens entre ĂȘtres humains par un concentrĂ© de savoirs et idĂ©es hĂ©tĂ©rogĂšnes tels qu'un ĂȘtre humain ayant besoin d'aide ou la nĂ©cessitĂ© de la crĂ©ativitĂ© par exemple. À l’usage, s’établit un type de lien social entre ĂȘtres humains via les machines pris entre la rĂ©duction propre Ă  tout modĂšle de l’objet sur lequel il porte, la flexibilitĂ© qu’offre la possibilitĂ© d’ajustement (le cĂŽtĂ© « learning ») et le sens donnĂ© Ă  l’action par l’utilisateur lambda. L’idĂ©ologie comme « mode de connaissance » du rĂ©seau sociotechnique est partie prenante de cette institutionnalisation en cours. Elle offre un cadre cognitif qui remet en cause la diversitĂ© produite par la division habituelle du travail sĂ©mantique au sein des ensembles sociaux en fournissant un modĂšle de lĂ©gitimitĂ©, soit le discours du « partage ». L’accent mis par cette thĂšse sur les « sciences de la gestion » et la notion de rĂ©seau l’inscrit dans le prolongement des Ă©tudes des trente derniĂšres annĂ©es sur cette « sociĂ©tĂ© informationnelle » de Manuel Castells, une « nouvelle reprĂ©sentation gĂ©nĂ©rale des sociĂ©tĂ©s » en rĂ©seau en suivant Luc Boltanski ou encore « l’esprit gestionnaire » qui s’empara des fonctionnaires d’État selon le sociologue Albert Ogien.From the point of view of a sociology of knowledge, contemporary research in Artificial Intelligence (AI) draws its originality by its interest in the modeling of ordinary knowledge, that knowledge engaged in everyday life. The companies Facebook or Google, the so-called GAFAM, as well as online music and video services, capture and model the facts and gestures of the average person in order to put the results of their calculations back into play in its very everyday life. The research in AI also deals with academic and professional knowledge as it did in the 1960s and 1970s, but this thesis will not focus on it. Within the framework of a sociology of science and technology, I question what We, as the Western civilization, do with technological development, about the world we build with the help of various techniques. My concern is not with the choice of research objects privileged by public and private laboratories, but with the uses, the outlets according to the very general question: In what way does such a technique modify or not our way of living? Now, this question is an exercise in foresight insofar as we often do not have enough hindsight on these techniques. Nevertheless, it remains a background concern of my research. Indeed, would these machine learning models find their place in a civilization that would not give as much importance to efficiency, productivity, profitability, science or work? Also, do they endorse the established social organization, or do they offer new possibilities of existence? Understanding the artifact minimally from a technical perspective and grasping from a sociological point of view the way in which researchers think about their objects sheds light on the main categories of thought that guide these uses and, if applicable, on the possible societal effects. In this case, the idea of modeling many activities of daily life is based on an a priori representation of it by researchers who are socially situated by their profession. What is this representation and how is it operationalized in the models? Put differently, what relationships to the world do engineers and computer scientists have through their professional, academic and ordinary knowledge? Thus, in this thesis, my work comes down to informing the social dimension specific to the studied technique. Based on interviews with AI researchers, the question is as follows: What is the knowledge and reasoning of the researchers at the core of the algorithms of contemporary artificial intelligence and which build a specific operational representation of social life? Expressed in sociological terms, this question becomes: In what way are learning models a new "concrete model of knowledge" for users et researchers according to the concept developed by the sociologist Gilles Houles? The so-called learning models underlie a relational constitution of human knowledge and of a relation to reality mediated by actions as a means of actualization of this knowledge. Summarized simply, the sociological concept of "concrete model of knowledge" objectifies the two modalities of existence of the human life that we find empirically under two computing concepts: symbolic (their mathematical model) and the “action” as "the computing agent" or "the one who acts", whether this concept is used or not by the researchers. In sum, these models in relation to each other and materialized in the notorious connected or "smart" objects (e.g. telephones, household appliances) turn social life into a sociotechnical network. Its operational side relies on the position of "third-party intermediary" or "technical social memory" in human-human relations via machines. I will draw upon the concept of "social memory" and "social morphology" developed by the sociologist Maurice Halbwachs. In other words, this network of connected objects and human beings comes down to the establishment of a particular collective cognitive framework, stemming from the social representations of specific professional groups, but put into play in the everyday life of all, that is to say an institutionalization in progress. Indeed, the diffusion and adoption of the models stem from a process of public recognition of underlying and already institutionalized knowledge, essentially mathematics and engineering, the implicit knowledge of the "management sciences" and a knowledge called "scientific" by researchers. More precisely, the process underway consists in the institution of human beings and learning machines in permanent links via connected objects ("Internet of Things"). In the end, it consists in the networking of "social regularities" obtained by classifications and regressions carried out by the data's owners. I will speak of a "sociotechnical morphology" or a "sociotechnical configuration". The figure of the anthropomorphic multipurpose robot, which is supposed to condense all the practical application of knowledge on AI, is replaced by that of computerized social relations as places where links between human beings are maintained by a concentration of heterogeneous knowledge and ideas, such as a human being in need of help or the need for creativity, for example. In use, a type of social link between human beings via the machines is established, caught between the reduction proper to any modelling of the object on which it concerns, the flexibility offered by the possibility of adjustment (the "learning" side) and the meaning given to the action by the lambda user. Ideology as a "mode of knowledge" of the socio-technical network is part of this ongoing institutionalization. It offers a cognitive framework that challenges the diversity produced by the usual division of semantic labor within social groups by providing a model of legitimacy, namely the discourse of "sharing". The emphasis placed by this thesis on the "management sciences" and the notion of network places it in the continuity of the studies of the last thirty years on this "informational society" of Manuel Castells, a "new general representation of societies" into a network according to Luc Boltanski, or the "managerial spirit" which took hold of the State civil servants according to the sociologist Albert Ogie

    With the appearance of the paradigms of the ambient intelligence and ubiquitaire robotics, we attend the emergence of new ambient intelligent systems to create and manage environments or intelligent ecosystems in a intuitive and transparent way. These environments are intelligent spaces characterized in particular by the opening, the heterogeneousness, the uncertainty and the dynamicitĂ© of the entities which establish(constitute) them. These characteristics so lift(raise) considerable scientific challenges for the conception(design) and the implementation of an adequate intelligent system. These challenges are mainly among five: the abstraction of the representation of the heterogeneous entities, the management of the uncertainties, the reactivity in the events, the sensibility in the context and the auto-adaptationAvec l'apparition des paradigmes de l'intelligence ambiante et de la robotique ubiquitaire, on assiste Ă  l'Ă©mergence de nouveaux systĂšmes intelligents ambiants visant Ă  crĂ©er et gĂ©rer des environnements ou Ă©cosystĂšmes intelligents d'une façon intuitive et transparente. Ces environnements sont des espaces intelligents caractĂ©risĂ©s notamment par l'ouverture, l'hĂ©tĂ©rogĂ©nĂ©itĂ©, l'incertitude et la dynamicitĂ© des entitĂ©s qui les constituent. Ces caractĂ©ristiques soulĂšvent ainsi des dĂ©fis scientifiques considĂ©rables pour la conception et la mise en Ɠuvre d'un systĂšme intelligent adĂ©quat. Ces dĂ©fis sont principalement au nombre de cinq : l'abstraction de la reprĂ©sentation des entitĂ©s hĂ©tĂ©rogĂšnes, la gestion des incertitudes, la rĂ©activitĂ© aux Ă©vĂ©nements, la sensibilitĂ© au contexte et l'auto-adaptation face aux changements imprĂ©visibles qui se produisent dans l'environnement ambiant. L'approche par composition dynamique de services constitue l'une des rĂ©ponses prometteuses Ă  ces dĂ©fis. Dans cette thĂšse, nous proposons un systĂšme intelligent capable d'effectuer une composition dynamique de services en tenant compte, d'une part, du contexte d'utilisation et des diverses fonctionnalitĂ©s offertes par les services disponibles dans un environnement ambiant et d'autre part, des besoins variables exprimĂ©s par les utilisateurs. Ce systĂšme est construit suivant un modĂšle multicouche, adaptatif et rĂ©actif aux Ă©vĂ©nements. Il repose aussi sur l'emploi d'un modĂšle de connaissances expressif permettant une ouverture plus large vers les diffĂ©rentes entitĂ©s de l'environnement ambiant notamment : les dispositifs, les services, les Ă©vĂ©nements, le contexte et les utilisateurs. Ce systĂšme intĂšgre Ă©galement un modĂšle de dĂ©couverte et de classification de services afin de localiser et de prĂ©parer sĂ©mantiquement les services nĂ©cessaires Ă  la composition de services. Cette composition est rĂ©alisĂ©e d'une façon automatique et dynamique en deux phases principales: la phase offline et la phase online. Dans la phase offline, un graphe global reliant tous les services abstraits disponibles est gĂ©nĂ©rĂ© automatiquement en se basant sur des rĂšgles de dĂ©cision sur les entrĂ©es et les sorties des services. Dans la phase online, des sous-graphes sont extraits automatiquement Ă  partir du graphe global selon les tĂąches Ă  rĂ©aliser qui sont dĂ©clenchĂ©es par des Ă©vĂ©nements qui surviennent dans l'environnement ambiant. Les sous-graphes ainsi obtenus sont exĂ©cutĂ©s suivant un modĂšle de sĂ©lection et de monitoring de services pour tenir compte du contexte d'utilisation et garantir une meilleure qualitĂ© de service. Les diffĂ©rents modĂšles proposĂ©s ont Ă©tĂ© mis en Ɠuvre et validĂ©s sur la plateforme ubiquitaire d'expĂ©rimentation du laboratoire LISSI Ă  partir de plusieurs scĂ©narii d'assistance et de maintien de personnes Ă  domicil

    UtilitĂ© des cadres interprĂ©tatifs pour la mise Ă  l’échelle d’innovations de promotion de la santĂ© : Ă©tude d’un cas concernant la petite enfance socialement dĂ©savantagĂ©e

    La mise Ă  l’échelle (scaling up) est un processus qui vise Ă  accroitre l’impact et la pĂ©rennitĂ© des effets d’innovations jugĂ©es prometteuses. Les publications Ă  ce sujet sont en progression importante dans le domaine de la santĂ© depuis une vingtaine d’annĂ©es. Toutefois, ces processus ont Ă©tĂ© Ă©tudiĂ©s de maniĂšre essentiellement technique malgrĂ© l’importance soulignĂ©e dans la littĂ©rature d’y prendre en compte des questions Ă©volutives de sens et de valeurs. Ceci est particuliĂšrement significatif pour les innovations de promotion de la santĂ©, construites sur les capacitĂ©s et collaborations de diffĂ©rents acteurs qui y partagent et nĂ©gocient diverses vues sur les problĂšmes, les actions Ă  entreprendre et leur but. Les contenus de ces innovations sont susceptibles d’évoluer de maniĂšre significative dans la mise Ă  l’échelle, et d’affecter la fonction d’impact et pĂ©rennitĂ© du processus. Peu d’études, cependant, mobilisent des thĂ©ories et mĂ©thodologies explicites Ă  cet Ă©gard. Cette thĂšse s’inscrit dans une vision sociale de la mise Ă  l’échelle et propose d’ajouter le concept de cadre interprĂ©tatif, ou « frame », Ă  son outillage conceptuel ; elle vise Ă  explorer l’utilitĂ© de cette notion au regard de la dynamique sociale de la mise Ă  l’échelle d’innovations complexes de promotion de la santĂ©. La thĂšse poursuit deux objectifs : 1) dĂ©velopper une articulation thĂ©orique de nature sociale pour la mise Ă  l’échelle intĂ©grant la notion de frame ; et 2) explorer l’utilitĂ© des frames comme ‘reprĂ©sentations’ pour documenter l’évolution du contenu des innovations au cours de leur mise Ă  l’échelle. La rĂ©ponse au premier objectif s’appuie sur une perspective de complexitĂ© des interventions en tant que rĂ©seaux dynamiques d’acteurs pour conceptualiser la mise Ă  l’échelle comme une expansion de rĂ©seaux oĂč le framing des questions de santĂ© Ă©volue au travers des relations entre acteurs. L’articulation thĂ©orique dĂ©veloppĂ©e combine la sociologie de l’innovation - thĂ©orie de l’acteur-rĂ©seau - et les perspectives des frames pour envisager ceux-ci en tant que ‘reprĂ©sentations’ ou ‘interactions’. En rĂ©ponse au second objectif, l’approche ‘reprĂ©sentationnelle’ aux frames est appliquĂ©e Ă  l’étude d’un cas de mise Ă  l’échelle d’innovation Ă©ducative Ă  caractĂšre intersectoriel concernant le dĂ©veloppement de jeunes enfants socialement dĂ©savantagĂ©s. Sur la base de documents cadres qui balisent les phases ‘pilote’ et ‘programme Ă  l’échelle’ de l'innovation, une analyse critique de frames est pratiquĂ©e au regard de la capacitĂ© du programme Ă  grande Ă©chelle Ă  supporter l’action sur les inĂ©galitĂ©s sociales de dĂ©veloppement des enfants et l’équitĂ©. Les rĂ©sultats illustrent des diffĂ©rences significatives de dĂ©finitions du ‘problĂšme’ du DJE et de la solution prĂ©conisĂ©e pour le programme Ă  grande Ă©chelle, qui constituent des amĂ©liorations, mais aussi certaines ‘dĂ©tĂ©riorations’ au regard des inĂ©galitĂ©s et de l’équitĂ©. En tant que constructions rĂ©alisĂ©es Ă  partir des ‘produits’ du processus social qui s’opĂšre dans le rĂ©seau intersectoriel des acteurs, les frames comme ‘reprĂ©sentations’ analysĂ©s de maniĂšre critique sont utiles pour expliciter et caractĂ©riser l’évolution des contenus des innovations et leurs consĂ©quences pour la mise Ă  l’échelle. MobilisĂ©s dans un Ă©change constructif avec les acteurs concernĂ©s, les frames pourraient constituer un outil intĂ©ressant pour favoriser la rĂ©flexivitĂ© Ă  l’égard de ces processus et de l’impact et de la durabilitĂ© des effets des innovations portĂ©es Ă  grande Ă©chelle. Cette thĂšse contribue de maniĂšre thĂ©orique Ă  la littĂ©rature de santĂ© publique en clarifiant l’utilitĂ© des frames et la maniĂšre dont ce concept peut ĂȘtre mobilisĂ© pour documenter la dynamique de la mise Ă  l’échelle d’innovations complexes de promotion de la santĂ©.Scaling up is a process that aims to increase the impact and sustainability of the effects of innovations deemed promising. Publications on this subject have markedly increased in the field of health over the past twenty years. However, these processes have essentially been studied in a technical way, despite the importance underlined in the literature to take into account their evolving meanings and values. This is particularly significant for health promotion innovations, built on the capacities and collaborations of different actors who share and negotiate various views on the problems, the actions to be taken and their goal. The contents of these innovations are likely to evolve significantly during scaling up, affecting impact and sustainability goals of the process. Few studies, however, mobilize explicit theories and methodologies in this respect. This thesis is part of a social vision of scaling up, and proposes to add the concept of ‘frame’ to its conceptual tools; it aims to explore the usefulness of this notion with regard to the social dynamics of scaling up health promotion innovations. The thesis pursues two objectives: 1) to develop a theoretical articulation of a social nature for scaling up, integrating the notion of frame; and 2) to explore the usefulness of frames as ‘representations’ to document the evolution of the content of innovations during their scaling up. The response to the first objective is based on a complexity perspective of interventions as dynamic networks of actors to conceptualize scaling up as an expansion of networks where the framing of health issues evolves through the relationships between the actors. The theoretical articulation developed combines the sociology of innovation - actor-network theory - and the perspectives of frames to consider them as 'representations' or 'interactions'. In response to the second objective, the 'representational' approach to frames is applied to the study of a scaling up case concerning an intersectoral educational innovation for the development of socially disadvantaged young children. On the basis of framework documents which mark out the 'pilot' and 'at scale program' phases of the innovation, a critical analysis of frames is carried out with regard to the capacity of the large-scale program to support action on the social inequalities in child development and equity. The results illustrate significant differences in definitions of the ECD ‘problem’ and of the recommended ‘solution’ for the at scale program, which constitute improvements, but also some ‘deteriorations’ with regard to inequalities and equity. As constructions made from the 'products' of the social process that takes place in the intersectoral network of actors, the frames as 'representations' critically analyzed are useful for explaining and characterizing the evolution of the contents of innovations and their consequences for scaling up. Mobilized in a constructive exchange with the actors concerned, the frames could constitute an interesting tool to promote reflexivity with regard to these processes and to the impact and sustainability of the effects of innovations carried out on a large scale. This thesis contributes theoretically to the public health literature by clarifying the usefulness of frames and the way in which this concept can be mobilized to document the dynamics of the scaling up of complex health promotion innovations

    Le financement basĂ© sur la performance au Cameroun : analyse de son Ă©mergence, sa mise en Ɠuvre et ses effets sur la disponibilitĂ© des mĂ©dicaments essentiels

    Full text link
    L'accĂšs aux mĂ©dicaments essentiels (ME) est un Ă©lĂ©ment clĂ© de la qualitĂ© des soins dans un systĂšme de santĂ©. Par ailleurs, le financement basĂ© sur la performance (FBP) attire de plus en plus l'attention des dĂ©cideurs comme une intervention pour amĂ©liorer la prestation des services de santĂ©, y compris l’accĂšs aux ME, dans les pays Ă  faible et moyen revenus (PFMR). MalgrĂ© l’intĂ©rĂȘt croissant de la recherche sur le FBP, trĂšs peu d’étude ont portĂ© sur la mise Ă  l’agenda d’une telle rĂ©forme ou son maintien Ă  l’ordre du jour au fil du temps, encore moins sur l’influence de celle-ci sur l’accĂšs aux ME dans les PFMR. A travers une analyse du programme de FBP au Cameroun, la prĂ©sente thĂšse vise Ă  faire avancer les connaissances en examinant les questions suivantes : qu’est-ce qui explique l’apparition du FBP au niveau de la politique nationale de la santĂ© et quel est l’impact de ce programme sur l’accĂšs aux ME? Le devis de recherche est celui d’une Ă©tude de cas et la dĂ©marche analytique s’appuie sur la combinaison des donnĂ©es qualitatives, Ă  travers des entrevues rĂ©alisĂ©es auprĂšs des acteurs clĂ©s du programme FBP au Cameroun, et quantitatives, issues de l’évaluation d’impact de ce programme. La perspective conceptuelle est celle des cycles de politique, du cadre de transfert des politiques et de la recherche interventionnelle. Les rĂ©sultats sont structurĂ©s en quatre articles scientifiques. La mise du FBP Ă  l’agenda au Cameroun s’est construite Ă  partir des rapports et Ă©vĂ©nements identifiant l'absence d'une politique de financement de la santĂ© adaptĂ©e comme une question importante Ă  laquelle il fallait s'attaquer (article 1). L'Ă©volution du discours politique vers une plus grande responsabilisation a permis de tester de nouveaux mĂ©canismes. Un groupe d'entrepreneurs politiques de la Banque mondiale, par le biais de nombreuses formes d'influence (financiĂšre, conceptuelle, fondĂ©e sur la connaissance et les rĂ©seaux) et en s'appuyant sur plusieurs rĂ©formes en cours, a collaborĂ© avec de hauts fonctionnaires du gouvernement pour mettre le programme FBP Ă  l'ordre du jour. Des organisations non gouvernementales internationales ont Ă©tĂ© recrutĂ©es au dĂ©but du programme pour assurer sa mise en Ɠuvre rapide. Toutefois, il a fallu transfĂ©rer ce rĂŽle aux organisations nationales pour assurer la pĂ©rennitĂ©, l'appropriation et l'intĂ©gration de l'intervention du FBP dans le systĂšme de santĂ© (article 2). L'expĂ©rience de ce transfert montre que les Ă©lĂ©ments favorisant la rĂ©ussite d’un tel processus incluent des directives structurĂ©es, une appropriation et planification conjointe de la transition par toutes les parties, et un soutien post-transition aux nouveaux acteurs. Les donnĂ©es qualitatives suggĂšrent que la mise en Ɠuvre du programme FBP influence l’accĂšs aux mĂ©dicaments essentiels par l’entremise de plusieurs facteurs, notamment une plus grande autonomie des formations sanitaires, une rĂ©gulation appliquĂ©e des Ă©quipes cadre de santĂ©, une plus grande responsabilisation des acteurs du mĂ©dicament et la libĂ©ralisation du systĂšme d’approvisionnement (article 3). Cependant, le programme a eu un impact trĂšs limitĂ© sur la disponibilitĂ© des ME (article 4). L'intervention n’a Ă©tĂ© associĂ©e Ă  aucune rĂ©duction des ruptures de stock de ME, sauf pour la planification familiale (PF), avec une hĂ©tĂ©rogĂ©nĂ©itĂ© des effets entre les rĂ©gions et les zones urbaines et rurales. Ces rĂ©sultats sont la consĂ©quence d'un Ă©chec partiel de la mise en Ɠuvre de ce programme, allant de la perturbation et de l'interruption des services Ă  une autonomie limitĂ©e des formations sanitaires dans la gestion des dĂ©cisions et Ă  un retard considĂ©rable dans le paiement des prestations.Access to essential medicines (EM) is a key element of quality of care in a health system. Accordingly, performance-based financing (PBF) is increasingly attracting the attention of policy makers as a promising intervention to improve health service delivery, including access to essential medicines, in low and middle-income countries (LMICs). Despite the growing interest in PBF research, very few studies have focused on how such a reform has been put on the agenda or how it has been maintained over time, much less how it has influenced access to EMs in low- and middle-income countries. Through an analysis of the PBF program in Cameroon, this thesis aims to advance knowledge by examining the following questions: What explains the emergence of PBF at the level of national health policy and what is the impact of this program on access to EMs? The research design is a case study and the analytical approach is based on a combination of qualitative data, through interviews conducted with key actors of the PBF program in Cameroon, and quantitative data from the impact evaluation of this program. The conceptual perspective is that of policy cycles, the policy transfer framework and intervention research. The results are structured into four scientific articles. Putting the PBF on the agenda in Cameroon was built from reports and events identifying the lack of an appropriate health financing policy as a critical issue that needed to be addressed (article 1). The evolution of political discourse towards greater accountability made it possible to test new mechanisms. A group of political entrepreneurs from the World Bank, through many forms of influence (financial, conceptual, knowledge-based and networked) and building on several ongoing reforms, worked with senior government officials to put the PBF reform on the agenda. International non-governmental organizations were recruited at the beginning of the programme to ensure its rapid implementation. However, this role had to be transferred to national organizations to ensure sustainability, ownership and integration of the PBF intervention into the health system (Article 2). The experience of this transfer shows that the elements for the success of such a process include structured guidelines, joint ownership and planning of the transition by all parties, and post-transition support to new actors. The implementation of the PBF programme influences access to essential medicines through several factors, including greater autonomy of health v facilities, enforced regulation of district medical teams, greater accountability of drug stakeholders and liberalization of the supply system (Article 3). However, the programme had a very limited impact on the availability of EMs (Article 4). The intervention was not associated with any reduction in EM stock-outs, except for family planning (FP), where the reduction was 34% (P = 0.028), with a heterogeneity of effects between regions and urban and rural areas. These poor results were likely the consequence of partial implementation failure, ranging from disruption and discontinuation of services to limited facility autonomy in managing decision‐making and considerable delay in performance payment

    Le BrĂ©sil a initiĂ© deux politiques publiques territoriales pour le dĂ©veloppement rural durable, le Programme National pour le DĂ©veloppement Durable des Territoires Ruraux (PRONAT) et le Programme Territoires de la CitoyennetĂ© (PTC). Ces politiques s’appliquent dans des Territoires Ruraux et visent entre autre, comme condition de leur effectivitĂ©, Ă  rĂ©-Ă©quilibrer les rapports de forces entre les acteurs au sein de la CollĂ©gialitĂ© pour le DĂ©veloppement Territorial (CODETER) de chaque Territoire Rural.

Nous partons de l’idĂ©e que les processus sociaux territorialisĂ©s donnent lieu Ă  des phĂ©nomĂšnes complexes qu’il est pertinent d’apprĂ©hender par l’approche systĂ©mique. Cela nous conduit Ă  proposer un modĂšle conceptuel des territoires ruraux considĂ©rĂ©s par les politiques publiques brĂ©siliennes en matiĂšre de dĂ©veloppement durable territorialisĂ©e, Ă  savoir le concept de systĂšme socioterritorial complexe, puis Ă  considĂ©rer les thĂ©ories des sciences sociales qui peuvent ĂȘtre mobilisĂ©es pour Ă©tayer la reprĂ©sentation de ces systĂšmes sous la forme computationnelle de sociĂ©tĂ©s artificielles. Nous avons Ă©valuĂ© deux courants sociologiques, l’individualisme mĂ©thodologie associĂ© Ă  la rationalitĂ© limitĂ©e Ă  partir de la Sociologie de l’Action OrganisĂ©e, et les SystĂšmes Sociaux de Luhmann plus attachĂ©s Ă  la thĂ©orie de la complexitĂ©. Nous avons dĂ©veloppĂ© un mĂ©tamodĂšle de la thĂ©orie luhmannienne qui s’avĂšre insuffisant pour analyser l’impact des politiques publiques sur le territoire, mais qui peut ĂȘtre vu comme un outil pour la validation de la thĂ©orie de Luhmann. D’autre part, nous avons adoptĂ© le mĂ©tamodĂšle SocLab, une formalisation computationnelle de la Sociologie de l’Action OrganisĂ©e, pour modĂ©liser, analyser et simuler les systĂšmes socioterritoriaux complexes. Pour Ă©valuer les effets des politiques publiques sur les Ă©changes symboliques entre les acteurs dans un modĂšle SocLab, nous proposons un indicateur, le taux de rĂ©ciprocitĂ©, basĂ© sur la thĂ©orie de la rĂ©ciprocitĂ©. Cette dĂ©marche a Ă©tĂ© appliquĂ©e Ă  l’étude de deux terrains, le Territoire Rural Sud de Sergipe et le Territoire Rural du Bas SĂŁo Francisco. Les donnĂ©es nĂ©cessaires Ă  l’élaboration d’un modĂšle SocLab ont Ă©tĂ© collectĂ©es par l’analyse documentaire et la recherche-action pour deux pĂ©riodes de rĂ©fĂ©rence, 2008-2012 et 2013-2017. À partir de l’étude analytique des modĂšles SocLab des deux territoires et de l’analyse des rĂ©sultats de leur simulation (notamment la capacitĂ© d’action, le pouvoir et le taux de rĂ©ciprocitĂ©), nous pouvons dĂ©gager des Ă©vidences pour affirmer que les politiques publiques PRONAT et PTC ont donnĂ© lieu, entre les deux pĂ©riodes considĂ©rĂ©es, Ă  un nouvel Ă©quilibre des rapports de forces entre les reprĂ©sentants de la sociĂ©tĂ© civile et les pouvoirs publics. L’approche SocLab s’est avĂ©rĂ©e effective pour systĂ©matiser la connaissance sur les territoires, mettre en Ă©vidence la structure sociale informelle, quantifier les relations d’échanges symboliques entre les acteurs, et pour tester diffĂ©rentes hypothĂšses sociologiques.Brazil has initiated two territorial public policies for a rural sustainable development, the National Program for Sustainable Development of the Rural Territories (PRONAT) and Citizenship Territory Program (PTC). These public policies aims, as a condition for its effectiveness, the equilibrium of the power relations between actors which participate in the Collegiate for Territorial Development (CODETER) of each Rural Territory. Our research studies the hypotheses that, in the Rural Territories submitted to the PRONAT and PTC public policies, the power and reciprocity relations between actors engaged in the CODETER effectively have evolved in favor of the civil society representatives to the detriment of the public powers, notably the mayors. This research has developed a method for modeling and simulation of power and reciprocity relations in the Rural Territories to assess the impact of the public policies for local development (PRONAT and PTC). We have started from the idea that the territorialized social processes are complex phenomena which can be understood by the systemic approach. This induced us to propose a conceptual model of rural territories considered by Brazilian public policies in terms of territorialized sustainable development, the concept of socioterritorial complex system, as they were established by the Brazilians public policies with focus on territorial sustainable development. Then, to consider the theories of social sciences which can be mobilized to support the representation of these systems in the computational form of artificial societies. We evaluated two sociological currents, the methodological individualism associated with the bounded rationality from the Sociology of the Organized Action, and the Luhmann’s Social Systems more attached to the complexity theory. We have developed a metamodel of the luhmannian theory that showed to be limited to the analyses of the impact of the territorial public policies, but it can be seen as a tool to instantiate parts of the Luhmann theory. On the other hand, we have adopted the metamodel SocLab, a computational formalization of the Sociology of the Organized Action, to model, analyze and simulate complex socio-territorial systems. To evaluate the effects of the public policies on the symbolic exchanges between actors in a SocLab model, we have proposed an indicator, the reciprocity rate, based on the reciprocity theory. This approach has been applied in two case studies, the Southern Rural Territory of Sergipe and the SĂŁo Francisco Rural Territory. The data needed to design the SocLab models were collected using literature review and performing action-research for two referential periods, 2008-2012 and 2013-2017. From the analytic study of the SocLab models of the two territories and the analysis of the results of their simulation (notably the capacity of action, the power and the rate of reciprocity), we can draw evidences to states that the public policies PRONAT and PTC resulted in a new balance of power relations between representatives of civil society and the public authorities between the two periods under review. The SocLab approach showed a strong effectiveness to systematize the knowledge about the territories, highlighting the informal social structure, quantifying symbolic exchange relations between actors, and testing different sociological hypotheses.O Brasil iniciou duas polĂ­ticas pĂșblicas territoriais para o desenvolvimento sustentĂĄvel, o Programa Nacional para o Desenvolvimento SustentĂĄvel de TerritĂłrios Rurais (PRONAT) e o Programa TerritĂłrios da Cidadania (PTC).

    Online shopping or e-shopping has changed the world of business and quite a few people have decided to work with these features. What their primary concerns precisely and the responses from the globalisation are the competency of incorporation while doing their businesses. E-shopping has also increased substantially in Malaysia in recent years. The rapid increase in the e-commerce industry in Malaysia has created the demand to emphasize on how to increase customer satisfaction while operating in the e-retailing environment. It is very important that customers are satisfied with the website, or else, they would not return. Therefore, a crucial fact to look into is that companies must ensure that their customers are satisfied with their purchases that are really essential from the ecommerce’s point of view. With is in mind, this study aimed at investigating customer satisfaction towards e-shopping in Malaysia. A total of 400 questionnaires were distributed among students randomly selected from various public and private universities located within Klang valley area. Total 369 questionnaires were returned, out of which 341 questionnaires were found usable for further analysis. Finally, SEM was employed to test the hypotheses. This study found that customer satisfaction towards e-shopping in Malaysia is to a great extent influenced by ease of use, trust, design of the website, online security and e-service quality. Finally, recommendations and future study direction is provided. Keywords: E-shopping, Customer satisfaction, Trust, Online security, E-service quality, Malaysia

    Langage, engagement et émotions (les ressources de la génération linguistique et de l'intégration émotionnelle dans le discours scientifique)

    L'Ă©motion et le discours scientifique sont traditionnellement deux domaines considĂ©rĂ©s comme incompatibles du fait du caractĂšre subjectif de la premiĂšre et des exigences d'objectivitĂ© et de neutralitĂ© du dernier. La thĂšse propose une Ă©tude des processus en Ɠuvre dans la gĂ©nĂ©ration des Ă©motions en relation avec la constitution du discours, et ensuite des stratĂ©gies ou modes d'intĂ©gration des phĂ©nomĂšnes de manifestations Ă©motionnelles dans le discours final. L'Ă©tude combine une approche psychologique et linguistique des Ă©motions et s'articule autour de la transition entre le domaine mental et celui de la prĂ©paration et de l'expression finale des Ă©motions gĂ©nĂ©rĂ©es dans le discours (lien entre l'Ă©valuation cognitive et l'Appraisal theory en linguistique). Une synthĂšse de grandes typologies des modes d'inclusion, ainsi que des grands types de manifestations de charges Ă©motionnelles-affectives globale est prĂ©sentĂ©e dans la thĂšse. Cette mĂȘme synthĂšse est issue de la recherche et de l'analyse de manifestations d'Ă©motions incluses volontairement ou non dans un corpus d'articles de la presse scientifique anglophone soumise Ă  comitĂ© de relecture. L'un des objectifs Ă©tant de dĂ©terminer si le discours scientifique prĂ©sente des manifestations de subjectivitĂ© des auteurs, et par quels biais ces phĂ©nomĂšnes de subjectivitĂ© et d'Ă©motion s'encodent dans des textes devant, selon les normes et conventions, ĂȘtre aussi objectifs et neutres que possible, quelle que soit la discipline concernĂ©e. A donc Ă©tĂ© soulevĂ©e la question de la part prise par l'Ă©motion dans le discours en gĂ©nĂ©ral, de sa constitution Ă  son expression.Emotion and scientific discourse are, by tradition, considered to be incompatible due to the subjective nature of the former and the objectivity requirements of the latter. The thesis deals with a study of the processes involved in emotion generation in relation with discourse generation. This is followed by the approach of the modes or strategies of inclusion of emotion manifestation phenomena in the final discourse. The study combines a psychological and linguistic approach of emotions, and revolves around the transition stage between the mental domain and that of language elaboration, leading to communicating the previously generated emotions in discourse (link between cognitive appraisal and the Appraisal theory in linguistics). The thesis sums up the broad categories of inclusion modes, as well as the main global emotion/affect load manifestation types. This very synthesis is the result of the research and analysis of emotion manifestations deliberately or accidentally included into a selection of articles sampled out from english-speaking peer-reviewed scientific press. One of the goals was to determine if scientific discourse contains and displays the authors' subjectivity and emotion manifestations, and how these phenomena are encoded in texts that are primarily meant (according to norms and conventions) to be as objective and neutral as possible, regardless of the subject. Thus was raised the question of the importance of the share taken by emotion in any discourse, from its generation to the moment it is uttered.BREST-SCD-Bib. electronique (290199901) / SudocSudocFranceF
