La fiducie a été introduite en droit français par une loi du 19 février 2007. Définie par l’article 2011 du Code civil, elle permet à une personne de transférer temporairement des éléments de son patrimoine vers un patrimoine fiduciaire qui est à la fois distinct du sien et de celui du fiduciaire qui en a la charge. Mécanisme sui generis relevant tant du droit des personnes que du droit des biens, la fiducie a été conçue par le législateur comme un mécanisme efficace de gestion et de sûreté. Près de dix ans après sa promulgation, sa pratique demeure pourtant confidentielle. Cette marginalité s’explique notamment par un régime juridique rigide et inadapté aux spécificités entrepreneuriales. Caractérisés tant par leur qualité de dirigeants que de propriétaires, les entrepreneurs sont pourtant les destinataires naturels de la fiducie. Ils cumulent en effet des considérations personnelles et professionnelles auxquelles l’opération fiduciaire répond utilement dans des juridictions étrangères. L’insuffisance du régime français de la fiducie est d’autant plus patente que les entrepreneurs disposent d’autres mécanismes d’affectation et/ou de rétention de propriété. Aussi, pour développer la fiducie, il apparaît nécessaire d’en libérer le potentiel en la rénovant au service des entrepreneurs. / The fiducie is a trust-like device that was introduced into French law by a statute of February 19th, 2007. Defined by Article 2011 of the Civil Code, it allows a grantor to temporarily transfer property to a fiduciaire that will not personally benefit from it. The fiducie is a sui generis device that was conceived for asset management and securitization purposes. Yet, nearly ten years after its enactment it remains rarely used. This scarcity can be explained by both the rigidity of its legal regime and its inadequacy for French entrepreneurs. As people who carry out managerial duties in firms that they partially or totally own, entrepreneurs should be particularly interested in using the fiducie for they face personal and professional issues which can be tackled by trust law in foreign jurisdictions. The inadequacy of its current regime is all the more problematic as French law offers various mechanisms that can produce similar legal consequences. Therefore, in order to develop the fiducie, one must renovate its regime with the objective of being useful to entrepreneurs.

Abstract A Kleinian Analysis of Organisations: Implications for Employee Health and Well-Being. This dissertation considers research that was conducted into the impact of organisational style of operation upon the health and well-being of individual employees. A Kleinian analysis of organisations, from a psychoanalytic perspective, highlights the defining characteristics of different organisations within the study. The intent of the thesis is to argue that the different types of organisations impact upon the health and well-being of their employees. Six organisations were studied using both qualitative and quantitative methods. Extensive interviews were conducted with 120 employees from those organisations. A Kleinian Analysis Questionnaire and a Kleinian Analysis Rating Scale (new psychoanalytic techniques aimed at promoting dialogue with employees) assisted in the analysis and positioning of the organisations. The findings suggested that organisations can be distinguished in Kleinian terms and that these differences produce a range of health effects for employees. In the qualitative parts of this research extensive discussions took place with the employees of organisations considered to be in either the Depressive position or the Paranoid – Schizoid positions. Using the Kleinian Analysis Questionnaire (KAQ), a great deal was revealed about the emotional lives of their organisations and the impact of these realities on their own individual emotional lives and on their mental and physical health. Organisational employee assistance programs (EAPs) were considered in terms of how support was extended to employees within the studied organisations and how the efficacy and utilization of EAPs were affected by organisational classification of either Depressive or Paranoid-Schizoid. A range of quantitative measures were employed in the study and included the broad health measures SF-36, the Satisfaction With Life Scale (SWLS), the Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW) and the Work Environment Scale (WES). Employees in the Depressive organisations described their workplaces as open, encouraging, creative, flexible and democratic in process. They described how the stated values and mission statements of their organisations were consistent with their own personal values and how their work as described by Gabriel (2002) enhanced their sense of self esteem and self image. There were abundant examples of their organisations providing support, described in psychoanalytic terms as ‘containment’. The quantitative results, in part, supported the qualitative results by demonstrating that the employees of Depressive organisations had a better rate of recovery from psychological issues arising from personal and workplace matters. In contrast, employees from Paranoid – Schizoid organisations described their workplaces as defensive, blaming, scapegoating, rigid and concrete, where organisational behaviour was often inconsistent with the organisation’s stated values and mission statements. They described some of the competitive activity as inconsistent with their own personal values and at times giving rise to anxiety. This discord had reflections on the emotional health of individuals. This was borne out in the quantitative aspects of the study which also found that the mental health of individuals and their rate of recovery from psychological issues were adversely affected by the lack of ‘containment’ afforded to them by their organisations. The results strongly demonstrated the value of EAPs as mechanisms of support for employees and revealed differences in the impact upon health and well-being of employees between the two Kleinian organisational types in addition to differences in the levels of utilization and involvement.

L’analyse statique est une tâche essentielle dans l’optimisation des requêtes et la vérification de la base de graphes RDF. Nous étudions des techniques d’analyse statique pour SPARQL, le langage standard pour l’interrogation des données du Web sémantique. Plus précisément, nous étudions le problème d’inclusion des requêtes et de l’analyse de l’indépendance entre les requêtes et la mise à jour de la base de graphes RDF.Nous sommes intéressés par le développement de techniques grâce à des réductions au problème de la satisfaisabilité de la logique.Nous nous traitons le problème d’inclusion des requêtes SPARQL en présence de l’opérateur OPTIONAL. L’optionalité est l’un des constructeurs les plus compliqués dans SPARQL et aussi celui qui rend ce langage plus expressif que les langages de requêtes classiques, comme SQL.Nous nous concentrons sur la classe de requêtes appelée "well-designed SPARQL", proposées dans la littérature comme un fragment du langage avec de bonnes propriétés en matière d’évaluation des requêtes incluent l’opération OPTIONAL. À ce jour, l’inclusion de requête a été testée à l’aide de différentes techniques: homomorphisme de graphes, bases de données canoniques, techniques de la théorie des automates et réduction au problème de la validité d’une logique. Dans cette thèse, nous utilisons la dernière technique pour tester l’inclusion des requêtes SPARQL avec OPTIONAL utilisant une logique expressive appelée «logique K». En utilisant cette technique, il est possible de régler le problème d’inclusion des requêtes pour plusieurs fragment de SPARQL, même en présence de schémas. Cette extensibilité n’est pas garantie par les autres méthodes.Nous montrons comment traduire a graphe RDF en un système de transitions, ainsi que une requête SPARQL en une formula K. Avec ces traductions, l’inclusion des requêtes dans SPARQL peut être réduite au test de la validité d’une formule logique. Un avantage de cette approche est d’ouvrir la voie pour des implémentations utilisant solveurs de satisfiabilité pour K.Nous présentons un banc d’essais de tests d’inclusion pour les requêtes SPARQL avec OPTIONAL. Nous avons effectué des expériences pour tester et comparer des solveurs d’inclusion de l’état de l’art.Nous présentons également un aperçu préliminaire du problème d’indépendance entre requête et mise à jour. Une requête est indépendante de la mise à jour lorsque l’exécution de la mise à jour ne modifie pas le résultat de la requête. Bien que ce problème ait été intensivement étudié pour des fragments de calcul relationnel, il n’existe pas de travaux pour le langage de requêtes standard pour le web sémantique. Nous proposons une définition de la notion de l’indépendance dans le contexte de SPARQL et nous établissons des premières pistes de analyse statique dans certains situations d’inclusion entre une requête et une mise à jour. / Static analysis is a core task in query optimization and knowledge base verification. We study static analysis techniques for SPARQL, the standard language for querying Semantic Web data. Specifically, we investigate the query containment problem and the query-update independence analysis. We are interested in developing techniques through reductions to the validity problem in logic.We address SPARQL query containment with optional matching. We focus on the class of well-designed SPARQL queries, proposed in the literature as a fragment of the language with good properties regarding query evaluation. SPARQL is interpreted over graphs, hence we encode it in a graph logic, specifically the modal logic K interpreted over label transition systems. We show that this logic is powerful enough to deal with query containment for the well-designed fragment of SPARQL. We show how to translate RDF graphs into transition systems and SPARQL queries into K-formulae. Therefore, query containment in SPARQL can be reduced to unsatisfiability in K.We also report on a preliminary overview of the SPARQL query-update problem. A query is independent of an update when the execution of the update does not affect the result of the query. Determining independence is especially useful in the contest of huge RDF repositories, where it permits to avoid expensive yet useless re-evaluation of queries. While this problem has been intensively studied for fragments of relational calculus, no works exist for the standard query language for the semantic web. We report on our investigations on how a notion of independence can be defined in the SPARQL context

Les structures en béton et béton armé de grandes dimensions, en particulier les enceintes de confinement, peuvent être sujettes à de la fissuration localisée suite à leur vieillissement ou dans le cas d’une forte sollicitation (APRP, par exemple). Afin d’optimiser les actions de maintenance, il est nécessaire de disposer d’un modèle prédictif de l’endommagement du béton. Ce phénomène se produit à une échelle matériau relativement petite et un modèle prédictif nécessite un maillage fin et une loi de comportement non linéaire. Hors ce type de modélisation ne peut être directement appliquée sur une structure de génie civil de grande échelle, le calcul étant trop lourd pour les machines actuelles.Une méthode de calcul est proposée, qui concentre l’effort de calcul sur les zones d’intérêt (parties endommagées) de la structure en éliminant les zones non endommagées. L’objectif est ainsi d’utiliser la puissance de calcul disponible pour la caractérisation des propriétés des fissures notamment. Cette approche utilise la méthode de condensation statique de Guyan pour ramener les zones élastiques à un ensemble de conditions aux limites appliquées aux bornes des zones d’intérêt. Lorsque le système évolue, un système de critères permet de promouvoir à la volée des zones élastiques en zones d’intérêt si de l’endommagement y apparaît. Cette méthode de condensation adaptative permet de réduire la dimension du problème non linéaire sans altérer la qualité des résultats par rapport à un calcul complet de référence. Cependant, une modélisation classique ne permet pas de prendre en compte les divers aléas impactant le comportement de la structure : propriétés mécaniques, géométrie, chargement… Afin de mieux caractériser ce comportement en tenant compte des incertitudes, la méthode de condensation adaptative proposée est couplée avec une approche de collocation stochastique. Chaque calcul déterministe nécessaire pour caractériser les incertitudes sur les grandeurs d’intérêt de la structure est ainsi réduit et les étapes de prétraitement nécessaires à la condensation sont elles-mêmes mutualisées via une deuxième collocation. L’approche proposée permet ainsi de produire pour un coût de calcul limité des densités de probabilités des grandeurs d’intérêt d’une grande structure. Les stratégies de résolution proposées rendent accessibles à l’échelle locale une modélisation plus fine que celle qui pourrait s’appliquer sur l’ensemble de la structure. Afin de bénéficier d’une meilleure représentativité à cette échelle, il est nécessaire de représenter les effets tridimensionnels des hétérogénéités. Dans le domaine du génie civil et nucléaire, cela concerne au premier chef les câbles de précontrainte, traditionnellement représentés en unidimensionnel. Une approche est donc proposée, qui s’appuie sur un maillage et une modélisation 1D pour reconstruire un volume équivalent au câble et retransmettre les efforts et rigidités dans le volume de béton. Elle combine la représentativité d’un modèle 3D complet et conforme des câbles lorsque le maillage s’affine et la facilité d’utilisation et paramétrage d’un modèle 1D. L’applicabilité des méthodes proposées à une structure de génie civil de grande échelle est évaluée sur un modèle numérique d’une maquette à l’échelle 1/3 de l’enceinte de confinement interne d’un réacteur de type REP 1300 MWe à double paroi. / Large-scale concrete and reinforced concrete structures, and in particular containment buildings, may undergo localized cracking when they age or endure strong loadings (LOCA for instance). In order to optimize the maintenance actions, a predictive model of concrete damage is required. This phenomenon takes place at a rather small material scale and a predictive model requires a refined mesh and a nonlinear constitutive law. This type of modelling cannot be applied directly on a large-scale civil engineering structure, as the computational load would be too heavy for the existing machines.A simulation method is proposed to focus the computational effort on the areas of interest (damaged parts) of the structure while eliminating the undamaged areas. It aims at using the available computing power for the characterization of crack properties in particular. This approach uses Guyan’s static condensation technique to reduce the elastic areas to a set of boundary conditions applied to the areas of interest. When the system evolves, a set of criteria allows to promote on the fly the elastic areas to areas of interest if damage appears. This adaptive condensation technique allows to reduce the dimension of a nonlinear problem without degrading the quality of the results when compared to a full reference simulation.However, a classical modelling does not allow to take into account the various unknowns which will impact the structural behaviour: mechanical properties, geometry, loading… In order to better characterize this behaviour while taking into account the various uncertainties, the proposed adaptive condensation method is coupled with a stochastic collocation approach. Each deterministic simulation required for the characterization of the uncertainties on the structural quantities of interest is therefore reduced and the pre-processing steps necessary to the condensation technique are also reduced using a second collocation. The proposed approach allows to produce for a reduced computational cost the probability density functions of the quantities of interest of a large structure.The proposed calculation strategies give access at the local scale to a modelling finer than what would be applicable to the full structure. In order to improve the representativeness at this scale, the tridimensional effects of the heterogeneities must be taken into account. In the civil and nuclear engineering field, one of the main issues is the modelling of prestressing tendons, usually modelled in one dimension. A new approach is proposed, which uses a 1D mesh and model to build a volume equivalent to the tendon and redistribute the forces and stiffnesses in the concrete. It combines the representativeness of a full conform 3D modelling of the tendon when the mesh is refined and the ease of use of the 1D approaches.The applicability of the proposed methodologies to a large-scale civil engineering structure is evaluated using a numerical model of a 1/3 mock-up of a double-wall containment building of a PWR 1300 MWe nuclear reactor.
