Dissertations / Theses on the topic 'Moral Observation'

Dans cette thèse, on s’intéresse aux contrats de partenariat public-privé (PPP). Un PPP est un contrat à long terme entre une entité publique et une partie privée, aussi appelée consortium, dans lequel le public externalise la construction et/ou la gestion d’un bien public. Le consortium prend le risque et la responsabilité de gérer le projet. Le public s’engage en contre partie à lui verser une rente. Cependant, les efforts du consortium pour améliorer la valeur sociale du projet ne sont pas observables par le public. C’est un problème de principal agent avec aléa moral où le principal est le public et l’agent est le privé. On suppose que le public paie le consortium continûment et l’effort de l’agent affecte le drift de la valeur sociale du projet. On suppose que le public est neutre au risque et le consortium est adverse au risque. Dans le chapitre 2 de la thèse, on considère un contrat perpétuel entre une entité publique et un consortium. On caractérise le contrat optimal dans ce cadre d’aléa moral. On utilise une formulation forte : on considère différentes filtrations correspondant à différents niveaux d’informations comme dans le contexte de contrôle stochastique avec observation partielle. Dans cette approche, on utilise des méthodes de martingale et de contrôle stochastique. Dans le chapitre 3, on considère un problème du partenariat public-privé avec horizon aléatoire, dans lequel le public a la possibilité d’arrêter le contrat à une date aléatoire et donne une compensation au consortium. On résout ce problème de contrôle stochastique avec un problème d’arrêt optimal dans ce cadre d’aléa moral. Dans ce chapitre, on utilise la formulation faible : on suppose que le consortium change la distribution de la valeur sociale du projet en changeant son drift et cela revient à considérer une nouvelle mesure de probabilité qui dépend de l’effort de l’agent. Dans le chapitre 4, on s’intéresse aussi au problème de partenariat public-privé avec un horizon aléatoire mais en utilisant la formulation forte. Puis, on traite la cadre de partage de risque : on suppose que le public et le consortium ont les mêmes informations. On analyse numériquement la valeur d’information. Dans le chapitre 5, on étudie l’existence d’une solution de l’équation d’Hamilton-Jacobi-Bellman qui apparaît dans notre étude théorique. Puis, on développe des résultats numériques pour la résolution numérique d’une équation Hamilton Jacobi-Bellman et l’inéquation variationnelle dans le cadre de notre étude numérique
In this thesis, we are interested in the contract with moral hazard for public private partnerships (PPP). PPP is defined as a long-term contract between a private party and a public entity, for the construction and/or the management of an asset or public service, in which the consortium takes the risks and a responsibility to manage the project. The public undertakes to pay him a rent. However, the effort that the consortium does to improve the social value of the project is not observable by the public. It is a principal-agent problem with moral hazard, in which the principal is the public and the agent is the consortium. We assume that the public pays the consortium continuously and the effort of the consortium affects the drift of the social value of the project. We assume that the agent is risk averse and the public is risk-neutral. In chapter 2 of the thesis, we consider a perpetual contract between a public entity and a consortium. We characterize the optimal contract in this moral hazard framework. We use the strong formulation : we consider different filtrations corresponding to the different level of information as in the context of stochastic control under partial observation. In this approach, we use martingale methods and stochastic control techniques. In chapter 3, we consider a public-private partnership problem with a random horizon, in which the public has the possibility to stop the contract at a fixed or a random time and gives compensation to the consortium. We solve this optimal stochastic control with optimal stopping problem in this context of moral hazard. We use the weak approach, that is the agent changes the distribution of the social value of the project by changing the drift and this amounts to considering a new probability that depends on the effort of the consortium. In the chapter 4, we also consider the problem of public-private partnership with a random horizon but using the strong formulation. Then, we deal with the risk-sharing framework, we assume that the public and the consortium have the same information. We analyze numerically the value of information. Chapter 5 focuses on the existence of a solution of the Hamilton Jacobi-Bellman equation that appears in our theoretical study. Then, we detail the numerical results for the numerical resolution of a Hamilton Jacobi-Bellman equation and variational inequality as part of our numerical study

Ce doctorat en philosophie explore le problème de l'incertitude normative, c'est-à-dire le problème éthique complexe qui consiste à savoir ce que nous devrions faire lorsque nous sommes incertains de ce que nous devrions faire. Nous menons notre thèse dans la tradition oubliée de la philosophie des sciences, celle de l'opérationnalisation. Cette dernière est une approche analytique approfondie qui permet de définir un cadre d’analyse pour conduire des études appliquées d'un un concept dont les implications empiriques ne sont, à l’origine, ni prouvées ni claires. Dans notre cas d'évaluation ou de choix éthique, l'opérationnalisation comprend deux dimensions principales : (1) fournir un cadre pour le raisonnement, la comparaison des valeurs des options et la prise de décision par des individus ou des groupes ; (2) fournir des preuves empiriques pour démontrer la pertinence du concept pour la recherche appliquée et les investigations scientifiques ultérieures. Nous divisons notre thèse en deux grandes parties suivant ces dimensions. Dans une introduction préalable, nous discutons l'incertitude normative et ses relations avec d'autres concepts éthiques et méta-éthiques. La première partie fournit un cadre complet pour comparer les valeurs des options, raisonner et prendre des décisions individuelles dans un contexte d'incertitude normative, en fonction des types et de la quantité d'informations dont dispose le décideur. La deuxième partie montre comment nous pouvons utiliser l’éthique et la philosophie du langage dans les méthodes d'enquête et établir l'incertitude normative comme un fait empirique en combinant ces deux disciplines. La conclusion résume les principales contributions de notre thèse
This Ph.D. in philosophy explores the normative uncertainty problem, i.e. the complex ethical problem of what should we do when uncertain about what we should do? We conduct our thesis in the tradition of the long-forgotten philosophy of science tradition of operationalization. The latter is a thorough analytical approach that allows for applied investigations of a concept whose empirical implications are neither proven nor clear. In the case of an ethical evaluation or choice problem, operationalization includes two main dimensions: (1) providing a framework for reasoning, comparing the values of options, and decision-making by individuals or groups; (2) providing empirical evidence to demonstrate the concept’s relevance for applied research and further scientific investigations. We divide our thesis into two main parts based on these dimensions. A preceding introduction addresses normative uncertainty and its relations to other ethical and meta-ethical concepts. Part I provides a comprehensive framework for comparing the values of options, reasoning, and making individual decisions under normative uncertainty, depending on the types and amount of information available to the decision-maker. Part II demonstrates how we may employ humanities in survey methods and establish normative uncertainty as an empirical fact by combining both disciplines. The conclusion summarizes our thesis’ main contributions

In negotiating research relationships with Aboriginal and Torres Strait Islander peoples, the question of colonisation runs deep. Often, as a gesture to counter the colonising effects of the research gaze, ‘participation’ is hailed as a methodological solution, as a means of healing and transforming power relations. In practice however, the ethical implications of research activities remain complex and contested (Cornwall, 2008, p.276). Much is written about why participatory methods offer remedial qualities of empowerment to counter colonialism in research, but there is little discussion of what happens when participatory research with Indigenous Australians does not operate as a smooth process of reclamation. Often, researchers avoid accounting for resistance to participation because this is viewed as a personal ‘failure’ to accurately represent the interests of a colonised group. The basis of these assumptions comes from a moral compulsion to alter power relations towards social justice: such logic cannot accept that ‘oppressed’ peoples would reject opportunities for empowerment. Yet, international literature (Kothari, 2001) shows that subjectivities comprising participatory research must be carefully considered when constructing research relationships. Drawing from a case study of my own participatory research experience with an Aboriginal community development organisation in Western Sydney, I consider how a non–Indigenous researcher might approach an understanding of their ethics when attempting to ‘decolonise’ their research. I reflexively investigate my own practice to offer a discussion of the ways in which researchers can understand how they come to determine what is ethical and what is not. My account begins with a description of a case study involving multiple forms of participation over a three–year period, which I explore as a series of ‘invited spaces’ (Cornwall, 2004). Drawing from my case study, I incorporate Foucault’s ethics (2005) by discussing how ethics codes create subjectivities, which not only shape the participants in the research, but also shape the kind of ‘selves’ researchers seek to become through participatory research. I consider the contingencies that have led to the construction of a remedial role for participatory methods in research involving Indigenous Australians by critically analysing the discourses within the National Health and Medical Research Council’s ethics guidelines. This research offers a multi–layered approach to reflexivity, by attending to transparency, interpersonal relationships, and a collective evaluation of the process with participants (Nicholls, 2009). Collective reflection about (re)presenting research findings to a variety of audiences highlights the importance of examining one’s own motives as crucial to ‘ethical’ practice. Researchers seeking to achieve a form of participation without resistance set themselves an impossible task. Resistance is not to be feared, but is to be expected within the mechanics of power relations amongst subjectivities within ‘communities’. Incorporating resistance into accounts of participatory research enables an ability to acknowledge ‘internal conflicts and contradictions’ (Fawcett and Hearn, 2004, p. 211) without deeming participation a failure. I argue that participation is a liminal space between trust and resistance, containing tensions and productive possibilities. By attending to one's ethics (Foucault, 2005), participatory researchers might now understand fluidity, uncertainty, and dynamism within research relationships as a rich source of reflexive work towards countering the colonising gaze.

The purpose of this study was: (a) to determine if a significant difference exists between leadership behavior of principals in effective schools when compared to leadership behavior of principals in less effective schools as perceived by teachers, (b) to determine if a significant difference exists in teacher morale in effective schools when compared to less effective schools, and (c) to determine if a significant difference exists in the comparison of the correlations between leadership behaviors of principals and factors contributing to teacher morale in effective schools when compared to less effective schools. A total of 158 teachers returned completed questionnaires. Leadership behavior of principals and teacher morale were measured by 83 teachers in effective schools and 75 teachers in less effective schools using the Leader Behavior Description Questionnaire, Form XII (LBDQ) and the Purdue Teacher Opinionnaire (PTO). A significant difference was found between effective schools and less effective schools in the leader behavior persuasiveness. Significant differences were also found in the correlations between teacher rapport with principal and initiation of structure and consideration. No significant differences were found in the total mean scores of leader behavior, total mean scores of teacher morale, or the correlation between the total mean scores of leader behavior and teacher morale. No significant differences were found in leader behavior dimensions of representation, demand reconciliation, tolerance of uncertainty, initiation of structure, tolerance of freedom, role assumption, consideration, production emphasis, predictive accuracy, integration, or superior orientation. No significant differences were found in teacher morale dimensions of teacher rapport with principal, satisfaction with teaching, rapport among teachers, teacher salary, teacher load, curriculum issues, teacher status, community support of education, school facilities and services, or community pressures. No significant differences were found in the correlations between teacher rapport with principal and representation, demand reconciliation, tolerance of uncertainty, persuasiveness, tolerance of freedom, role assumption, production emphasis, predictive accuracy, integration, superior orientation; rapport among teachers and demand reconciliation, initiation of structure, role assumption, integration; curriculum issues and tolerance of freedom; teacher status and consideration; or school facilities and services and production emphasis. Recommendations based on the findings were given.

Subtropical mode water is a voluminous body of water in the ocean whose main feature is the homogeneity in both vertical structure and horizontal extension. The subtropical mode water (STMW) of the southwest Atlantic is formed between the months of July and October near the Brazil-Malvinas confluence and along the Brazil Current recirculation gyre. The formation region extends on the order of 3000 km zonally, from 20°W to 50°W, and 1000 km meridionally, from 30°S to 40°S, and it is typically about 170 m thick. In situ data from pressure-equipped inverted echo sounders (PIES) installed in the western portion of the basin, along 34.5°S, are available from 2009 to the present. These data after processed and calibrated can provide an unprecedented description of the STMW involving processes since its formation at the surface until the final stage of its residence in the interior of the ocean. Temperature and salinity data estimated by the PIES are based on empirical look-up tables that relate the acoustic travel time with the baroclinic structure of the ocean. This technique is known as the Gravest Empirical Mode (GEM), and here it is used to detect profiles containing homogeneous segments of temperature and salinity that characterize the mode water. The GEM method was seasonally corrected to reconstruct surface variability necessary for STMW formation. The interannual covariance between STMW layer thickness and the Brazil Current was calculated, but no significant correlation at that time scale was observed. The mode water layer detected was about 220 m ± 55 m thick on all sites, agreeing with previous studies.
A água modal subtropical é um grande volume de água no oceano cuja característica principal é a homogeneidade nas estruturas vertical e horizontal. A água modal subtropical do sudoeste do Atlântico é formada entre os meses de julho e outubro perto da confluência Brasil-Malvinas e ao longo da recirculação da Corrente do Brasil. A região de formação se estende na ordem de 3000 km zonalmente, de 20°W a 50°W e 1000 km meridionalmente, de 30°S a 40°S, e tipicamente tem cerca de 170 m de espessura. Dados in situ de ecossondas invertidas com sensor de pressão (PIES) instaladas na porção ocidental da bacia, ao longo de 34,5°S, estão disponíveis a partir de 2009 até o presente. Estes dados após o processamento e calibração podem fornecer uma descrição sem precedentes da Água Modal Subtropical do Atlântico Sul envolvendo processos desde sua formação na superfície até o estágio final de sua permanência no interior do oceano. Os dados de temperatura e salinidade estimados pelos PIES são baseados em tabelas de referência (look-up tables) que relacionam o tempo de retorno do sinal acústico com a estrutura baroclínica do oceano. Esta técnica é conhecida como o Gravest Empirical Mode (GEM),e aqui é usado para detectar perfis contendo segmentos homogêneos de temperatura e salinidade que caracterizam a água modal. Foi aplicada uma correção sazonal ao método GEM para reconstruir a variabilidade da superfície necessária para a formação STMW. A covariância interanual entre a espessura da camada STMW e a corrente do Brasil foi calculada, mas não foi observada correlação significativa naquela escala de tempo. A camada de água em modo detectada foi de cerca de 220 m ± 55 m de espessura em todos os sites, concordando com estudos prévios.

The purpose of the study is to investigate violin teachers’ view of and use of bowing technique in their teaching. The study´s research questions concern how do violin teachers represent their view of bow technique? And how do violin teachers design their teaching in bow technique? The study is qualitative, and data has been collected through semi structured interviews with four different violin teachers at music and cultural schools. The theoretical starting point of the study is social semiotic perspective. The interviews were recorded by audio and video and were then transcribe and analyzed. The analysis was conducted with tools from the chosen theoretical framework. In the study's results, the violin teachers' view of bow technique is described and how they design their teaching in bow technique. The themes presented are string techniques such as tone formation, bow technique such as posture, bow technique such as instrument technology, material resources in teachingandbodily and sounding resources in teaching. The result shows many differences but also similarities in the interviewed violin teachers' statements, but all highlight the significance of the bow technique in teaching and its function. In the final chapter of the study, the result is discussed in relation to previous literature and research, and to the social semiotic perspective of the study. The themes presented are teaching from a social semiotic perspectiveand bow technique linked to posture and tone formation. The method discussion, the importance of work and continued research is also mentioned.

Cette thèse a pour objet d’étudier la création à Lyon de l’association « La Sauvegarde de l’enfance » sous le régime de Vichy. L’étude de cet « objet » a nécessité de désenclaver la période, afin de mettre davantage en évidence le rôle majeur des années de l’Entre-deux guerres dans l’élaboration d’un dispositif de prise en charge de l’enfance irrégulière et endanger moral. Et par conséquent d’inscrire cette étude dans la double continuité : années 30/Vichy, Vichy/Reconstruction. Ce temps étudié, met en évidence le rôle central que va jouer, tout au long des années 1935-1949, la neuropsychiatrie infantile dans l’élaboration du dispositif de prise en charge de l’enfance. Cela dans un contexte de forte médicalisation desquestions sociales. Au travers de cet objet historique, « La Sauvegarde de l’enfance », nous avons pu étudier au plus près la construction d’un rapport complexe entre l’Etat en pleine affirmation de son autorité, de renforcement de ses pouvoirs et l’Association comme expression de la société civile. Ce rapport complexe, fait de tensions, d’injonctions, et de reconnaissance mutuelle, s’inscrit dans une tradition élaborée dans le dernier tiers du XIXe siècle qui est celle du « concordat social », de la nécessité d’un compromis qui produit ce que Pierre Rosanvallon nomme « le jacobinisme amendé ». La Sauvegarde de l’enfance à Lyon, sera, entre 1943 et 1949, l’expression de cet amendement du jacobinisme. Cette étude a enfin permis de montrer, dans un contexte historique singulier, le rôle important des acteurs individuels ou collectifs, acteurs qui le plus souvent s’inscrivent au sein de réseaux et qui élaborent des stratégies. Ainsi au coeur de l’Occupation allemande, sous l’Etat Français de Vichy dans sa période la plus noire, des acteurs associatifs et politiques se donnent des marges de manoeuvres, négocient. Cette France au plus près du terrain a pu exprimer et réaliser ses vues, du moins les négocier, grâce à un contexte qui, paradoxalement, ne faisait pas de la protection de l’enfance une priorité de l’Etat. C’est là, au cours de cette séquence historique majeure, que les politiques de protection de l’enfance entrent dans un âge nouveau, que s’élabore un dispositif : fait d’un discours, d’une législation, d’institutions, de professionnels notamment
The purpose of this PhD dissertation is to study the creation process of the association « Sauvegarde de l’enfance » (protection/safeguard of childhood) in Lyon under the Vichy regime. This PhD disseration has required to open the period to the years which have preceded and followed the Vichy regime in order to evidence among others the major contribution of the inter-war period to the development of a scheme aiming at taking care of children in an irregular situation and in moral danger. And as a result to place this study in the double continuity : 30s/Vichy and Vichy/postwar reconstruction. The studied period highlighths the central role played by child neuropsychiatry through the years 1935-1949 in the development of the childcare system/scheme, in a context of heavy medicalisation of social matters. Through the historical object « The Protection/safeguard of childhood » it has been possible to study closely the development of a complex relation between the State - in a period where its authority grew significantly and got strengthened - and the associations / « the Association » as representative of the civil society. This complex relation, made of tensions, injonctions and mutual recognition, ties in a tradition developed during the last third of the 19th Century, the tradition of « social concordat », of the necessity of a compromise which developed into what Pierre Rosanvallon calls « the amended jacobinism ». The « Sauvegarde de l’enfance » in Lyon will be between 1943 and 1949 the expression of this amendment to jacobinism. This study has eventually allowed to show in a special historical context the important role of individual and collective actors, who most often relate to networks and work out strategies. Thus in the darkest period of the German occupation under the Vichy State its, associative and political actors negotiate. This France in contact with day-to-day realities has had the possibility to express and achieve its visions/intentions/aims/targets, at least negotiate them, thanks to a context where the State paradoxically did not prioritize the protection of childhood. It is in this period, during this major historical sequence, that policies aiming at protecting childhood entered into a new period ; this is when a care scheme has developped, made especially of an argumentation, a legislation and institutions

At the heart of this thesis is the work of Simone Weil; at its centre is a critique of Iris Murdoch's The Sovereignty of Good . Murdoch was greatly inspired by Simone Weil and also wrote in the tradition of Anglo-Saxon philosophy; a thorough critique of her book therefore provides an opportunity to discuss critical concepts in Weil's work in a context meaningful to philosophers in the analytic tradition. I demonstrate the prima facie implausibility of Murdoch's portrayal of a moral agent as a psychologically isolated rather than socially situated human being; I then critique her views by appealing both to psychological evidence and to insights owing to linguistic philosophy. I show, in contrast, that on Well's conception humans are socially and politically situated thinking beings endowed with a faculty of attention and capable of consent. I further show how Weil's view of human relationships acknowledges the harm and isolation that people can experience, and only experience, as social beings, and which are constitutive of the phenomenon that she calls "affliction". As an experience of the lack of a referring context, affliction cannot be either acknowledged or named. The insight of linguistic philosophy that meaning is tied to context proves helpful to understanding this. Finally, I extend the notion of context beyond the social and argue for a four-stage schematism in the thought of Simone Weil; this schematism begins with the individual, passes on to the social world, then to the natural world viewed as necessity, and then to God

The United Nations works towards sustainable development for present and future generations and therefore set their target for 2030 to attain seventeen goals, not only to help future generations meet their own needs, but also to help this present generation to be sustainable. In view of all that, one realizes that world leaders released a new, holistic paradigm shift known as systemic thinking. The new paradigm falls back to the ancient old tension between parts and the whole. Nowadays, 21st leaders reject the emphasis on the parts with its linear, rational and competitive edge. At this time in history, the new paradigm embraces a nonlinear, integrative, intuitive and holistic view of life with a moral vision at the tail end. As a result, a strong emphasis on the earth as a living being called world leaders to emphasize the moral calling of humans towards the planet. At it's heart, the calling is spiritual in order to keep the planet sustaining itself at all costs. Therefore, leaders tune themselves in to sense the future- that's to say they continuously solve complex problems fast and secure with simple solutions. Forecasts of the future is derived from sensing, experience and observation of best future possibilities. Presencing means leaders envision the future and then act on what they sense. Sources of leadership vision are foresight that leads to insight and action. Before any of the above will be effective, some preparation has to be done. Preparing the mind, heart and will to open and to resist judgementalism, cynicism and fear lays the groundwork for implementing sustainable development principles. Sensing requires stillness or mindfulness; becoming quiet to wait for the right moment to act. Strong and impulsive reactions to promote the egoistic self should be quenched by asking oneself “Who am I?”, “What is my task?” .This study examined the role of motion leadership towards sustainable development in Canadian secondary schools in Alberta Province. A qualitative investigation at three independent schools in the province of Alberta near the greater Calgary area was done. Data were gathered by means of face-to-face, in-depth interviews. Each interview lasted thirty minutes. Each school’s principal, assistant-principal and a teacher have been interviewed. Data were also gathered through document analysis from the Alberta education websites. The findings revealed that, to a greater or lesser extent, motion leadership is present throughout. Findings showed that openness in the schools are present and that leaders do try to get rid of their blind spots. Participants were in favour of mindfulness sessions at their schools and work towards a borderless migration to spread the sustainable development principles. The study, in the light of the new paragdigm, recommends that firstly, motion leaders need to remain clear on their moral vision, namely to serve the planetary wellbeing through sustainable development principles. Secondly, the study recommends that every motion leader has to help to turn the beam of observation on themselves in order to see that they are part of a holistic system and part of the problem the system might encounter. Thirdly, both parents and the wider community should be intricately involved in learning to become system citizens.

Department of Defense for the establishment of the new age elite national army, with the government reform, continue to promote the strength of structural adjustment; This research studies at this stage, "the Pristine of the Program" organizational change, members of the organization in response to sudden changes of environment, the condition of derivative Significant supporting measures, how to impact morale characterization,to developing continuation programs as a manager, or adjust the leadership method of reference. In this study, the quality management group of the Air Force Logistics repair factory for the study, the use of Participant observation, supplemented by Free representation method, summarized in the following conclusions: 1.The organizational change morale characterization upward; however, when it is involved morale dimensions and management related topics, showing that affect the morale of members is reduced, formed to enhance the morale of obstacles. 2.Environment variation, and the relative supporting measures impact , the morale ‘s characterization is upward; except to the extent that the work situations involving external environmental factors (such as major government policy), and the organization's internal management capacity, the bureaucracy relations and other issues, the lower the morale of the members of the organization. 3.High team spirit organization,in the face of rapid changes of external environment and internal organization of the operational functions is imperfect,management capability can not be convinced of the context,the members still peers to help one another、to encourage, the operation of the organization is still not affected; except to the extent that organizations morale shaken symptoms become apparent,the morale of the obstacles become increasingly serious, must immediately confront and take improvement measures. According to the above results, four suggestions are addressed: 1.That motivates employees to participate in change and policies to promote opinions communication process. 2.To create a happy working environment, to terminate the ex-tide, and the members of the organization are willing for organizational effectiveness. 3.The human resources management system refined, emphasis on employee performance measurement and future development. 4.Management Leadership ability to re-learn, put in to develop the process of education and experience.

De part sa capacité de très haute résolution angulaire, l'interférométrie optique est une technique d'observation parfaitement adaptée pour l'étude des zones les plus internes d'objets complexes tels que les étoiles jeunes et leur environnement proche, les noyaux actifs de galaxie ou les binaires en interactions. Bien qu'étant entrée dans l'aire de l'imagerie avec des instruments de nouvelle génération tels que PIONIER au VLT Interferometer, ou MIRC à CHARA (combinant 4 ou 6 télescopes), l'interférométrie optique est forte- ment handicapée par les perturbations atmosphériques. Les suiveurs de franges sont des instruments développés spécifiquement dans le but de compenser ces perturbations, permettant ainsi d'augmenter la sensibilité des interféromètres d'un facteur 10 à 1000. Dans la première partie de ma thèse, je présente le résultat d'études visant à définir un concept optimal de suiveur de frange de seconde génération pour le VLTI. Je démontre en premier lieu l'intérêt du filtrage spatial monomode pour le suivi de frange, ainsi que l'importance capitale de l'Optique Adaptative pour l'interférométrie, y compris pour des télescopes de 1 à 2 mètres de diamètre. Je dé- termine ensuite la meilleure méthode de mesure de la position des franges et la configuration de recombinaison des télescopes offrant le meilleur compromis entre sensibilité et robustesse du suivi de frange. Ces études ont finalement menées au concept de suiveur de frange POPS proposé à l'ESO par l'IPAG. Dans la seconde partie de ma thèse, je me suis intéressée aux binaires en interaction, objets en mesure d'apporter des réponses à un vaste champs d'études, du fait de la diversité des processus physiques en jeu. Leur étude à très haute résolution angulaire, permise par l'interférométrie optique, se montre parfaitement complémentaire des techniques classiques employées jusque là. Je me suis intéressé au cas du système SS Leporis, observé avec les instruments AMBER et PIONIER du VLTI. Nous avons obtenu les premières reconstructions d'images d'une binaire en interaction avec le VLTI. Ces observations nous ont permis d'avoir une nouvelle vision de ce système méconnu, ouvrant par la même la voie à l'étude des binaires en interaction au VLTI.
