Ce mémoire propose une analyse du rôle qu’exerce le collectionneur d’art, un acteur ayant une capacité accrue à agir concrètement sur une part importante du monde artistique. La capacité des collectionneurs à agir comme mécènes pour certains artistes, à acheter leurs œuvres, à les vendre, à les exposer, sont autant d’actions qui ont un impact direct sur la carrière des artistes. Plus le collectionneur est reconnu comme une instance capable de légitimer le travail d’un artiste, plus il peut voir sa sphère d’influence devenir importante. Pour adéquatement saisir les effets qu’ont ces actions sur l’entièreté du monde artistique, nous avons choisi de prendre comme objet d’étude une figure particulière qui exemplifie le méga-collectionneur, Charles Saatchi. En assumant lui-même, tour-à-tour, plusieurs rôles dans le monde de l’art, il est reconnu comme un agent apte à reconnaître la légitimité d'une proposition artistique. La première partie de ce mémoire nous permet d'observer l'élaboration d'une véritable tradition du collectionnement et ses principaux acteurs derrière celle-ci. Dans un deuxième temps, le mémoire présente les théories qui expliquent l'avènement du pouvoir prépondérant reconnu au méga-collectionneur. Sont ainsi observés les principes de coopération, propres aux « mondes de l'art », ainsi que les phénomènes de médiation. Finalement, nous étudions, décrivons et définissons les actions et les interactions des divers acteurs et agents qui participent au réseau dont Saatchi est le centre afin de cerner la place qu’il occupe dans le champ culturel, donc sa propre légitimité et sa capacité à reconnaître et à consacrer d’autres acteurs. / This thesis proposes an analysis of the role exerted by the new art collector, an agent with an increased capacity to act on an important part of the art world. The ability of collectors to act as patrons for artists, to purchase their works, to sell and expose them, are all actions that have a direct impact on the careers of artists. The more a collector is recognized as an authority able to legitimize the work of an artist, the more he can see its sphere of influence grow. To adequately perceive the effects of these actions on the art world, we have selected a particular figure that exemplifies the new supercollector, Charles Saatchi. By assuming several roles in the art world, he is perceived as an agent capable of recognizing the legitimacy of an artistic proposal. The first part of this thesis will observe the development of a tradition of collecting and the key agents behind it. Subsequently, this research presents the theories that explain the advent of the all encompassing power of the supercollector. Therefore, the theory of cooperation, specific to the « art worlds », and the phenomena of mediation are observed. Finally, we study, describe and define the actions and interactions of the various agents involved in the network of Saatchi. This will allow us to identify his place in the cultural field, so his own legitimacy and ability to recognize and bestow legitimacy to other actors.

Réalisé en cotutelle avec l'Université de Grenoble. / La complexité des mondes virtuels ne cesse d’augmenter et les techniques de modélisation classiques peinent à satisfaire les contraintes de quantité nécessaires à la production de telles scènes. Les techniques de génération procédurale permettent la création automatisée de mondes virtuels complexes à l’aide d’algorithmes, mais sont souvent contre-intuitives et par conséquent réservées à des artistes expérimentés. En effet, ces méthodes offrent peu de contrôle à l’utilisateur et sont rarement interactives. De plus, il s’agit souvent pour l’utilisateur de trouver des valeurs pour leurs nombreux paramètres en effectuant des séries d’essais et d’erreurs jusqu’à l’obtention d’un résultat satisfaisant, ce qui est souvent long et fastidieux. L’objectif de cette thèse est de combiner la puissance créatrice de la génération procédurale avec un contrôle utilisateur intuitif afin de proposer de nouvelles méthodes interactives de modéli- sation de mondes virtuels. Tout d’abord, nous présentons une méthode de génération procédurale de villages sur des terrains accidentés, dont les éléments sont soumis à de fortes contraintes de l’environnement. Ensuite, nous proposons une méthode interactive de modélisation de cascades, basée sur un contrôle utilisateur fin et la génération automatisée d’un contenu cohérent en regard de l’hydrologie et du terrain. Puis, nous présentons une méthode d’édition de terrains par croquis, où les éléments caractéristiques du terrain comme les lignes de crêtes sont analysés et déformés pour correspondre aux silhouettes complexes tracées par l’utilisateur. Enfin, nous proposons une métaphore de peinture pour la création et l’édition interactive des mondes virtuels, où des tech- niques de synthèse d’éléments vectoriels sont utilisées pour automatiser la déformation et l’édition de la scène tout en préservant sa cohérence. / The complexity required for virtual worlds is always increasing. Conventional modeling tech- niques are struggling to meet the constraints and efficiency required for the production of such scenes. Procedural generation techniques use algorithms for the automated creation of virtual worlds, but are often non-intuitive and therefore reserved to experienced programmers. Indeed, these methods offer fewer controls to users and are rarely interactive. Moreover, the user often needs to find values for several parameters. The user only gets indirect control through a series of trials and errors, which makes modeling tasks long and tedious. The objective of this thesis is to combine the power of procedural modeling techniques with intuitive user control towards interactive methods for designing virtual worlds. First, we present a technique for procedural modeling of villages over arbitrary terrains, where elements are subjected to strong environmental constraints. Second, we propose an interactive technique for the procedural modeling of waterfall sceneries, combining intuitive user control with the automated generation of consistent content, in regard of hydrology and terrain constraints. Then, we describe an interactive sketch-based technique for editing terrains, where terrain features are extracted and deformed to fit the user sketches. Finally, we present a painting metaphor for virtual world creation and editing, where methods for example-based synthesis of vectorial elements are used to automate deformation and editing of the scene while maintaining its consistency.

Poetics of space in The Alexandria Quartet is created by multilevel structures. This poetics is closely connected to the main space of the story - Alexandria, which is at the same time one of the novel's topics. Each level is suggested in connection to various theoretical conceptions which are subsequently used for my own analysis. Alexandria is initially an aesthetic coulisse of the story which is portrayed by descriptive passages. Strongly subjective and lyrical descriptions of the city establish overall impression of the story and potentially support reader's experiential illusion. Alexandria and its specificity is further modulated and thematised by its special macroscopic conditions which border Alexandria as an autonomous fictional space with its own rules within the novel's fictional world. Part of poetics of the space in this novel is also portraying spatio-temporal aspect of the reality (chronotope) no only on the level of the story, but also on the level of storytelling. Alexandria is further explicit rhetoric and also through semantic indexation personified and enters semantic relations with the main characters and events. Each level is complementary to another and all are part of the semantic gesture of the novel. Alexandria becomes a separate symbol, mythical entity which importance is...

So far the academical reception of Czech chronicle by Václav Hájek of Libočany was criticized for not being considerate of the early modern period literary context. It can be concluded from this paper's analysis of previous critiques and interpretations of Hájek's chronicle and from the excerption of key aspects of the theory of fictional worlds, that there is a lack of knowledge about the early modern period discoursive praxis, which defined the fictionality of text(s), as well as about formal and methodical aspects of this kind of work. Only through a thorough inspections of these two aspects it is possible to understand Czech chronicle and similar works as both historiographical sources and components of literary progress. This paper is comprised of selection of theoretical tools meant to identify the distinctions between fictional and non-fictional narratives, of overview of Hájek's chronicle's reception in compendia and editorial comments, and finally of a synthesis of theoretical conclusions and practical classifications of Hájek's chronicle, meaning this paper evaluates their expressive value regarding the current (non-)fictional state of Czech chronicle.

Le clown, personnage culturel et social, se construit par l'interaction avec son public et son milieu d'intervention. Le fait que le clown corresponde si durablement dans les représentations à la caricature d'un personnage de cirque, amène à se demander si le clown n'est pas victime de son image, pourtant si positive il fut un temps. Ce constat amène à réfléchir directement sur l'identité des clowns et leur réalité actuelle. Comprendre comment et pourquoi les clowns ont évolué ces dernières années revient à questionner à la fois les éléments de permanence et d'unicité qui les constituent mais aussi les facteurs de variations et de variabilité de leur travail artistique. L'analyse des transformations passées et en cours de la figure du clown à travers un état des lieux sur la figure du clown puis la construction identitaire des nouveaux clowns et enfin leurs formes diverses et récentes, donne au sujet une profondeur et une compréhension plus vaste. Ce travail, relevant d'une approche sociologique, a pour objectif de rendre compte d'une identité, d'une profession et d'un art qui entrent en lien avec des enjeux sociaux, politiques et économiques des sociétés contemporaines et occidentales. Questionner les ressources que le clown met en œuvre à l'heure actuelle pour survivre est une façon de comprendre son identité sociale et par là, la société dans laquelle il vit. L'existence sociale des nouveaux clowns est en rapport constant avec les arts frères que sont la danse, le théâtre, le cirque, mais aussi avec les mondes des amuseurs publics que constituent par exemple les humoristes desquels ils se nourrissent et avec lesquels ils se confrontent dans un même temps. / The clown, a cultural and social character, is shaped in interaction with his public and his environment. Yet, the fact that the figure of the clown is consistently associated with the caricatural representation of the circus character leads to question if the clown could be a victim of his own image, which was once so positive. Furthermore, this highlights the relevancy of reflecting directly on the identity of the clowns and their present reality. Understanding how and why the clown has evolved in recent years requires identifying the elements of durability and uniqueness which establish the clown, but also of the variations and variability of the artistic work. The analysis of both past and present transformations through an overview of the figure of the clown and the identity-building of the “new clowns” and finally, their diverse and recent forms, allows for a deeper and wider understanding of the subject. The objective of this thesis is, through a sociological approach, to highlight an identity, a profession and an art form and it's relation to social, political and economic issues in contemporary western societies. To question the resources that the clown must presently mobilize to survive allows an understanding of his social identity and thus also of the society in which he lives. The social existence of the “new clowns” is in constant interaction with related artistic disciplines such as dance, theater, and circus, but also with the worlds of public entertainers, for example humorists, in whom they find inspiration at the same time as grounds to confront ideas.

The thesis analyzes the possibilities of application of the fictional worlds theory as a possible basis for a different literary-theoretical approach to the study of literary texts. Not being a mere literature research, the thesis inquires into issues which are necessarily connected with the fictional worlds theory and which have been so far rarely dealt with, if discussed at all. It contributes to the discussion on advantages and drawbacks of the mimetic approach and of the fiction theory, it analyzes the possible applicability of the fictional worlds theory in literary history, it attempts to determine the correlation between the Seymour Chatman's textual types and the fiction theory nomenclature, and last but not least the thesis deals with the possibilities of this theory in the fictional worlds of lyrical poetry.

Souvent, lorsque les locuteurs d'une langue n'ont pas accès à l'item conventionnel pour étiqueter un objet ou un événement, ils étendent, consciemment ou inconsciemment, le sens d'un autre item lexical disponible. Ce phénomène se produit particulièrement au cours de la phase d'acquisition lexicale des jeunes enfants. Lorsqu'une telle sur-extension sémantique va au-delà de la catégorie d'objet ou d'événement conventionnellement dénotée par l'item lexical produit, il s'agit d'une sur-extension catégorielle et l'énoncé produit est d'allure métaphorique: par exemple, « déshabiller la pomme » pour l'action peler une pomme est un énoncé d'allure métaphorique. Tout d'abord, cette thèse a permis de développer SLAM, un système de résolution lexicale automatique des métaphores produites en situation de manque du mot. SLAM s'appuie, d'une part, sur l'analyse syntaxique de grands corpus et, d'autre part, sur la structure Petit Monde Hiérarchique des réseaux lexicaux de synonymie. Par exemple, à partir des énoncés « elle déshabille* la pomme » ou « les bras* de l'arbre », SLAM permet d'obtenir les interprétations suivantes: respectivement, « elle pèle une pomme » et « les branches de l'arbre ».Ensuite, cette thèse a permis d'étudier spécifiquement la dynamique d'acquisition du lexique des verbes qui se stabilise après celui des noms. D'une part, des outils méthodologiques pour l'étude inter-linguistique de la dynamique d'acquisition du lexique des verbes ont été élaborés: (a) un cadre méthodologique pour la construction de procédures d'identification des sur-extensions sémantiques catégorielles des verbes; (b) une méthodologie pour le repérage des stimuli visuels d'action sans biais culturel. D'autre part, les liens entre la structure des réseaux lexicaux de synonymie et la dynamique d'acquisition du lexique des verbes en français et en mandarin ont été mis au jour. Après avoir pointé des différences dans la dynamique d'acquisition du lexique des verbes par les jeunes enfants natifs du français et du mandarin, cette étude a servi à construire le score REFLEX, mesure du degré d'acquisition du lexique des verbes, qui permet de catégoriser automatiquement les jeunes enfants vs adultes en français et en mandarin. / When speakers have no access to the conventional label for an object or an event, they tend to extend, consciously or not, the meaning of another available lexical label. This phenomenon often occurs during the lexical acquisition stage of young children. When a such overextension goes beyond the conventional object or event category denoted by the produced label, it is a categorical overextension and the produced utterance is metaphorical: for instance, ``to undress an apple'' for the action to peel an apple is metaphorical.During this thesis, I developed SLAM, a computational system that automatically gives lexical solutions to metaphors filling a lexical gap. SLAM is based on a syntactic analysis of large corpora and on the Hierarchical Small World structure of synonymy networks. For instance, when the produced utterances are ``elle déshabille* une pomme'' ( ``she undresses* an apple'') or ``les bras* de l'arbr'' (``the arms* of the tree''), SLAM gives the interpretations here after: respectively, ``elle pèle une pomme'' (``she peels an apple'') and ``les branches de l'arbre'' (``the branches of the tree'').Then, I studied the dynamics of verb lexicon acquisition that is longer than noun lexicon acquisition. On the one hand, I built methodological tools for inter-linguistic studies of the dynamics of verb lexicon acquisition: (a) a methodological frame to build procedures to identify categorical overextensions of verbs; (b) a methodology to detect visual stimuli containing actions without cultural bias. On the other hand, I highlighted the links between the structure of synonymy networks and the dynamics of verbs lexicon acquisition in french and mandarin. This study has indicated differences in dynamics of verb lexicon acquisition between french and mandarin native speakers. Finally, I built REFLEX, a score that indicates the degree of verb lexicon acquisition and automatically categorizes young children vs adults in french and mandarin.

Selon nous, la face cachée des Rougon-Macquart réside dans l’articulation de deux histoires : l’une légitime, affichée, déclarée - l’histoire naturelle et sociale d’une famille sous le Second Empire - l’autre cachée, illégitime, non déclarée - l’histoire culturelle et intellectuelle également sous le Second Empire. Cette histoire a culturelle a pu être mise en place car elle repose sur les deux aspects développés par cet auteur : l’aspect social en découpant la société en cinq mondes et l’aspect naturel ou héréditaire (la reproduction). En effet, avec cette histoire culturelle, nous retrouvons ce même découpage en cinq mondes : le monde des arts et des lettres, le monde des sciences, le monde des sciences humaines, le monde de l’information et de la communication et un monde à part (la mythologie et la religion). Cette histoire culturelle a également été envisagée sous l’angle de la reproduction textuelle et non plus sexuelle avec la mise en place d’une véritable machinerie à reproduire les textes-sources (ou textes insérés). La bande-reproductrice ou la bande-annonce qui définit le type de texte ; l’annonce (ou le texte reproduit). Le roman expérimental résiderait davantage dans la mise en place de cette autre histoire qui, de manière souterraine, a permis à Zola de réfléchir sur les différentes méthodes de composition et d’écriture qu’impliquent cette reproduction textuelle comme l’acte de reproduire. Si nous avons défini ces cinq mondes culturels , nous nous sommes davantage attachées à étudier le monde de l’information et de la communication, et en particulier le monde journalistique. Une telle approche nécessite sa prise en compte pour redéfinir tant l’esthétique zolienne que naturaliste. / According to our view, the hidden of the Rougon-Macquart lies in expression of two histories : a legitimate one, which is stated, declared – the natural and social history of family under the Second Empire – and the other one, which is hidden, illegitimate and undeclared – the cultural and intellectual history under the Second Empire as well. The set up of this cultural history was made possible because it relies on the two aspects developpedby this autor :the social aspect by dividing society into five worlds and the natural or hereditary one (reproduction). Indeed, with this cultural history, wie find the same division :the world of Arts and literature, the world of sciences, the world of human sciences, the world of information and of communication and a world apart (mythology and religion). This cultural history was also considered from the angle of textual reproduction, and not fromthe angle of sexual reproduction with the setting up of an authenthic machinery able to reproduce the source texts (or inserted texts). This machinery includes an announcer or reproducer, the announce or reproduction verb in charge of defining the source text ; the reproductive or announcing substance which definies the sort of text ; the announce (or the reproduced text).The experimental novel would more streuously reside in the setting up of this other history which in an underlying way enabled Zola to ponder on the different compsition and writing methods wich this textual reproduction involves as the act of reproducing. If we have defined these five cultural worlds, we have even more studied the world ofinformation and of communication, and the journalistic world in particular. This sort of approach requieres to take it into account in order to redefine Zola’s and Naturalim’s aesthetics.

This work is divided into two major topics: many-worlds (or multiverse) theories in cosmology and Richard Dawids string theory-based epistemology, or non-empirical confirmation theory, as he calls it. The former is discussed in part I and the latter in part II of this dissertation. These topics are not intertwined in this work, as are not the essays that compose each chapter: in part I, first chapter, probability arguments that are presented in the literature as indications a multiverse must exist are accessed, whereas the second chapter is concerned with analyzing the metaphysical view that motivates many-world theory building, namely, the need to find unconditioned explanations in physics. Non-empirical confirmation theory is built upon three arguments, the No Alternatives Argument, the Meta-Inductive Argument from the Success of Other Theories in the Research Program and the Unexpected Explanatory Coherence Argument. Each compose a chapter in part II of this work, as they encode different philosophical issues that require for their assessment different tools from the philosophers arsenal. Skeptical conclusions are drawn at the end of each chapter. The wide spectrum of questions this work touches are designed to give at least slight indication that critical exploration of foundational theories made upon grounds familiar to philosophers can be found as internal to scientific practice itself, if that practice is concerned with the discovery, refinement and revision of fundamental theories. / Este trabalho divide-se em dois grandes tópicos: teorias de muitos mundos (ou multiverso) em cosmologia e a epistemologia não-empírica, embasada na teoria das cordas, de Richard Dawid. O primeiro é discutido na parte I e o segundo compõe a parte II deste trabalho. Tais tópicos não estão ligados, e a problemática desenvolvida em cada capítulo deste trabalho é, em larga medida, independente das demais: no primeiro capítulo da parte I argumentos probabilísticos indicados a literatura em prol da existência de muitos mundos são analisados, enquanto no segundo capítulo os pressupostos metafísicos que motivam a construção de teorias de muitos mundos em cosmologia, a saber, o fundamentalismo que busca explicações não-condicionadas para os fenômenos com os quais lida a física, são discutidos. A teoria da confirmação não-empírica de Dawid, tema da segunda parte deste trabalho, tem por base três argumentos, a saber, o argumento das alternativas inexistentes, o argumento meta-indutivo do sucesso de outras teorias no programa de pesquisa e o argumento da coerência explanatória inesperada. Cada um destes argumentos é tema de um capítulo neste trabalho, posto que desvelam problemáticas filosóficas distintas que requerem, por sua natureza, ferramentas de análise diferentes. Conclusões céticas são indicadas ao final de cada capítulo. O amplo espectro de questões que aborda este trabalho é desenhado com o propósito de fornecer ao menos vaga indicação de que a exploração crítica de teorias fundamentais, levadas a cabo a partir de vieses familiares ao filósofo, pode ser vista como interna à própria prática científica, se esta prática é preocupada com a descoberta, refinamento e revisão de teorias fundamentais.

It takes Bakhtin s dialogical theory as it basis, more specifically the concepts of architectonics and authorship (which implies those of chronotope and exotopy, as well as some proposals of authors from Film Theory, especially Robert Stam. Having a practical character, it aims to examine in which way the movie is architectonically organized for senses creation based on the articulation of different chronotopical perspectives. We discuss how the cinematographic work in analysis works with time, as well as the way this reveals the specificity of the authorial project, in order to show in which aspects this work of Iñárritu is emblematic regarding the possibility of creating simultaneity amid a chronological scenes succession. The work resorts to the concept of spheres-worlds, which refers to the ambience in which live the characters, spheres that join in terms of what we call a shattered mirror . As for the adopted proceedings, we describe the characters and their relationships and existences, considering more carefully three insertions of the same accident, vital for the narrative, and we evaluate the points of view of key characters regarding the accident, aiming at revealing the dynamics of architectonics concerning the enunciatively project of the author and the production of senses in the studied film narrative / Este trabalho caracteriza-se como uma análise dialógica da arquitetônica do filme Amores Perros (Iñarritu, México, 2000). Tem como referencial a teoria dialógica de Mikhail Bakhtin, mais especificamente os conceitos de arquitetônica e autoria (que envolvem o cronotopo e a exotopia), bem como o de teóricos de Teoria de Cinema, notadamente, Robert Stam. De caráter prático, busca examinar de que maneira se organiza arquitetonicamente o filme na criação de sentidos, a partir da articulação de diferentes perspectivas cronotópicas. Problematizamos a maneira como a obra cinematográfica, em análise, lida com o tempo, assim como a maneira como isso revela a especificidade do projeto autoral, a fim de demonstrar em que aspectos essa obra de Iñárritu é emblemática em relação à possibilidade de criar simultaneidade em meio a uma sucessão cronológica de cenas. O trabalho recorre ao conceito de esferas-mundo que remete às ambiências em que vivem as personagens, esferas que se integram nos termos do que denominamos espelho estilhaçado . Quanto aos procedimentos adotados, são descritas as personagens e suas relações e vivências, considerando, mais detidamente, as três inserções de um mesmo acidente, vital para a narrativa, e avaliamos os pontos de vista de personagens-chave quando do acidente, buscando verificar as dinâmicas da arquitetônica quanto ao projeto enunciativo do autor e à produção de sentidos na narrativa fílmica em questão
