[EN] The Ph.D. Thesis "Atomic decompositions and frames in Fréchet spaces and their duals" presented here treats different areas of functional analysis with applications. Schauder frames are used to represent an arbitrary element x of a function space E as a series expansion involving a fixed countable set {xj} of elements in that space such that the coefficients of the expansion of x depend in a linear and continuous way on x. Unlike Schauder bases, the expression of an element x in terms of the sequence {xj}, i.e. the reconstruction formula for x, is not necessarily unique. Atomic decompositions or Schauder frames are a less restrictive structure than bases, because a complemented subspace of a Banach space with basis has always a natural Schauder frame, that is obtained from the basis of the superspace. Even when the complemented subspace has a basis, there is not a systematic way to find it. Atomic decompositions appeared in applications to signal processing and sampling theory among other areas. Very recently, Pilipovic and Stoeva [55] studied series expansions in (countable) projective or inductive limits of Banach spaces. In this thesis we begin a systematic study of Schauder frames in locally convex spaces, but our main interest lies in Fréchet spaces and their duals. The main difference with respect to the concept considered in [55] is that our approach does not depend on a fixed representation of the Fréchet space as a projective limit of Banach spaces. The text is divided into two chapters and appendix that gives the notation, definitions and the basic results we will use throughout the thesis. The first one focuses on the relation between the properties of an existing Schauder frame in a Fréchet space E and the structure of the space. In the second chapter frames and Bessel sequences in Fréchet spaces and their duals are defined and studied. In what follows, we give a brief description of the different chapters: In Chapter 1, we study Schauder frames in Fréchet spaces and their duals, as well as perturbation results. We define shrinking and boundedly complete Schauder xviiframes on a locally convex space, study the duality of these two concepts and their relation with the reflexivity of the space. We characterize when an unconditional Schauder frame is shrinking or boundedly complete in terms of properties of the space. Several examples of concrete Schauder frames in function spaces are also presented. Most of the results included in this chapter are published by Bonet, Fernández, Galbis and Ribera in [13]. The second chapter of the thesis is devoted to study ¿-Bessel sequences, ¿-frames and frames with respect to ¿ in the dual of a Hausdorff locally convex space E, in particular for Fréchet spaces and complete (LB)-spaces E, with ¿ a sequence space. We investigate the relation of these concepts with representing systems in the sense of Kadets and Korobeinik [34] and with the Schauder frames, that were investigated in Chapter 1. The abstract results presented here, when applied to concrete spaces of analytic functions, give many examples and consequences about sampling sets and Dirichlet series expansions. We present several abstract results about ¿-frames in complete (LB)-spaces. Finally, many applications, results and examples concerning sufficient sets for weighted Fréchet spaces of holomorphic functions and weakly sufficient sets for weighted (LB)-spaces of holomorphic functions are collected. Most of the results are submitted for publication in a preprint of Bonet, Fernández, Galbis and Ribera in [12]. / [ES] La presente memoria "Descomposiciones atómicas y frames en espacios de Fréchet y sus duales" trata diferentes áreas del análisis funcional con aplicaciones. Los frames de Schauder se utilizan para representar un elemento arbitrario x de un espacio de funciones E mediante una serie a partir de un conjunto numerable fijado {xj} de elementos de este espacio de manera que los coeficientes de la reconstrucción de x dependen de forma lineal y continua de x. A diferencia de las bases de Schauder, la expresión de un elemento x en términos de la sucesión {xj}, i.e. la fórmula de reconstrucción para x, no es necesariamente única. Las descomposiciones atómicas o los frames de Schauder son un estructura menos restrictiva que las bases, porque un subespacio complementado de un espacio de Banach con base tiene siempre un frame de Schauder natural, que se obtiene a partir de una base del superespacio. Incluso cuando el subespacio complementado tiene una base, no hay una forma sistemática de encontrarla. Las descomposiciones atómicas aparecen en aplicaciones al procesamiento de señales y la teoría de muestreo, entre otras áreas. Recientemente, Pilipovic y Stoeva [55] han estudiado el desarrollo en serie en límites inductivos y proyectivos (numerables) de espacios de Banach. En esta tesis empezamos un estudio sistemático de los frames de Schauder en espacios localmente convexos aunque nuestro interés principal son los espacios de Fréchet y sus duales. La diferencia principal respecto del concepto considerado en [55] es que nuestra aproximación no depende de una representación fijada del espacio de Fréchet como límite proyectivo de espacios de Banach. El texto queda dividido en dos partes y un apéndice que incluye la notación, las definiciones y los resultados básicos que usaremos a lo largo de la tesis. La primera parte se centra en la relación entre las propiedades de un frame de Schauder en un espacio de Fréchet E y la estructura del espacio. En el segundo capítulo se definen y estudian los frames y las sucesiones de Bessel en espacios de Fréchet y sus duales. A continuación, presentamos una breve descripción de los capítulos: En el Capítulo 1, estudiamos los frames de Schauder en los espacios de Fréchet y sus duales así como los resultados de perturbación. Definimos los frames de Schauder contractivos y acotadamente completos en espacios localmente convexos, estudiamos la dualidad de estos dos conceptos y su relación con la reflexividad del espacio. Caracterizamos cuándo un frame de Schauder incondicional es contractivo o acotadamente completo en términos de las propiedades del espacio. También se presentan varios ejemplos de frames de Schauder en espacios de funciones concretos. La mayoría de los resultados incluidos en este capítulo están publicados por Bonet, Fernández, Galbis y Ribera en [13]. El segundo capítulo de la tesis está centrado en el estudio de las sucesiones de ¿-Bessel, ¿-frames y frames respecto de ¿ en el dual de un espacio localmente convexo de Hausdorff E, en particular, para espacios de Fréchet y espacios (LB) completos E, con ¿ un espacio de sucesiones. Investigamos la relación de estos dos conceptos con los sistemas representantes en el sentido de Kadets y Korobeinik [34] y con los frames de Schauder, considerados en el Capítulo 1. Los resultados abstractos presentados aquí, cuando los aplicamos a espacios de funciones analíticas concretos, nos dan muchos ejemplos y consecuencias sobre los conjuntos de muestreo y los desarrollos en serie de Dirichlet. Presentamos varios resultados abstractos sobre ¿-frames en espacios (LB) completos. Finalmente, recogemos muchas aplicaciones, resultados y ejemplos alrededor de los conjuntos suficientes para espacios de Fréchet de funciones holomorfas y conjuntos débilmente suficientes para espacios pesados (LB) de funciones holomorfas. La mayoría de los resultados incluidos en este capítulo están enviados para publicar e / [CAT] La tesi "Descomposicions atòmiques i frames en espais de Fréchet i els seus duals" presentada ací tracta diferents àrees de l'anàlisi funcional amb aplicacions. Els frames de Schauder s'utilitzen per tal de representar un element arbitrari x d'un espai de funcions E com una reconstrucció en sèrie a partir d'un conjunt numerable fixat {xj} d'elements en aquest espai tal que els coeficients de la reconstrucció de x depenen de forma lineal i continua de x. A diferència de les bases de Schauder, l'expressió d'un element x en termes d'una successió {xj}, i.e. la fórmula de reconstrucció per a x, no és necessàriament única. Les descomposicions atòmiques o els frames de Schauder són una estructura menys restrictiva que les bases, donat que un subespai complementat d'un espai de Banach amb base sempre té un frame de Schauder natural, el qual és obtingut a partir d'una base del superespai. Inclòs quan el subespai complementat disposa de una base, no hi ha una forma sistemàtica per tal de trobar-la. Les descomposicions atòmiques apareixen en aplicacions a processat de senyals i teoría de mostreig entre altres àrees. Recentment, Pilipovic i Stoeva [55] han estudiat els desenvolupaments en sèrie en límits inductius o projectius (numerables) en espais de Banach. En aquesta tesi comencem un estudi sistemàtic dels frames de Schauder en espais localment convexos, tot i que el nostre interés està en els espais de Fréchet i els seus duals. La diferència més important amb el concepte estudiat en [55] és que el nostre estudi no depén de una representació fixada del espai de Fréchet com a límit projectiu de espais de Banach. El text està dividit en dos capítols i un apèndix que ens aporta la notació, definicions i els resultats bàsics que utilitzarem al llarg de la tesi. El primer dels capítols està centrat en la relació entre les propietats de un frame de Schauder en un espai de Fréchet E i la estructura del espai. En el segon capítol es defineixen i estudien els frames i les successions de Bessel en espais de Fréchet i els seus duals. En el que segueix, donem una breu descripció dels diferents capítols: En el Capítol 1, estudiem els frames de Schauder en els espais de Fréchet i els seus duals, així com els resultats de pertorbació. Definim els frames de Schauder contractius i fitadament complets en espais localment convexos, estudiem la dualitat d'aquests dos conceptes i la seua relació amb la reflexivitat del espai. Caracteritzem, en quines situacions, un frame de Schauder incondicional és contractiu o fitadament complet en termes de les propietats del espai. També presentem alguns exemples de frames de Schauder concrets en espais de funcions. La majoria dels resultats inclosos en aquest capítol estan publicats per Bonet, Fernández, Galbis i Ribera en [13]. El segon capítol de la tesi està centrat en el estudi de les successions ¿-Bessel, ¿-frames i frames respecte de ¿ en el dual d'un espai localment convex de Hausdorff E, en particular, per a espais de Fréchet i espais (LB) complets E, amb ¿ un espai de successions. Investiguem la relació d'aquests dos conceptes amb sistemes representants en el sentit de Kadets i Korobeinik [34] i amb els frames de Schauder, que han sigut investigats en el Capítol 1. Els resultats abstractes presentats ací, quan els apliquem a espais de funcions analítiques concrets, ens donen molts exemples i conseqüències sobre els conjunts de mostreig i els desenvolupaments en sèrie de Dirichlet. Presentem diversos resultats abstractes sobre ¿-frames en espais (LB) complets. Finalment, recollim moltes aplicacions, resultats i exemples al voltant dels conjunts suficients per a espais de Fréchet de funcions holomorfes i conjunts dèbilment suficients per a espais pesats (LB) de funcions holomorfes. La majoria dels resultats inclosos en aquest capítol estan sotmesos a publicació per Bonet, Fernández, Galbis i Ribera en [12]. / Ribera Puchades, JM. (2015).

Psychotherapy is an interpersonal encounter where a therapist collaborates with clients to facilitate a healing process. Due to the personal nature of the therapeutic encounter, the therapist requires the necessary skills and knowledge, as well as a differentiated sense of self. The importance of supporting the psychotherapy trainee’s own differentiation process seemed to have been neglected in research in recent years. In South Africa there has recently been increasing pressure to select larger groups of trainees which has the risk that the tending to differentiation would further be neglected. The purpose of this research study is to reemphasise the importance of differentiation of self of the psychotherapy trainee by examining my own process of differentiation during my psychotherapy training. This study introduces the reader to these concepts and explores psychotherapy training in general and the Unisa training method specifically. The research design of this study is autoethnography which falls in the realm of social constructionism and the coding method is Thematic Data Analysis. The research findings as reflected in the two global themes namely individuation; and gaining and strengthening authentic relationships, seem to accurately reflect the process of differentiation. The specific training method of the Unisa training team in combination with the way in which I engaged with this process seemed important for the facilitation of this process of differentiation. / Psychology / M.A. (Clinical Psychology)

In this study, the intersections between Equine Assisted Psychotherapeutic interventions and adolescence are explored. Equine Assisted therapeutic work has recently gained much popularity in the field of psychology, due to many reported benefits, which include the value of the use of the horse as a tool in psychotherapy. Adolescence is acknowledged to be a difficult transitional phase, punctuated with many challenges, such as identity development. As this study is conducted by a trainee psychotherapist and researcher, the work also contains a reflexive exploration of these fields, with personal reflections regarding the researcher‟s own experience in the fields. This study is framed as a transtheoretical bricolage, which includes elements of reflexivity, heuristics, transpersonal, and phenomenological research approaches. Data was gathered from individual interviews with co-researchers, focus group interviews, personal reflections, and inclusion of non-verbal information from the horses who formed part of this study. Data analysis was done by means of a Thematic Data Analysis. The research findings reflect themes on different levels, which are: content themes, process themes, meta-reflections on the research process, and a meta-analysis of the research and individual developmental process which took place in the production of this work / Psychology / M.

Lors des années 2000, le paysage télévisuel américain a été profondément bouleversé par l’arrivée d’Internet. Que ce soit dans sa production, sa création ou sa réception, l’évolution rapide des technologies numériques et l’apparition des nouveaux médias ont contraint l’industrie télévisuelle à changer, parfois contre son gré. C’est le cas de la chaîne généraliste américaine NBC, pour qui cette période de transition a été particulièrement difficile à traverser. Au coeur de ce moment charnière dans l’histoire de la télévision aux États-Unis, la sitcom Community (NBC, 2009-2014; Yahoo!Screen, 2015) incarne et témoigne bien de différentes transformations amenées par cette convergence entre Internet et la télévision et des conséquences de cette dernière dans l’industrie télévisuelle. L’observation du parcours tumultueux de la comédie de situation ayant débuté sur les ondes de NBC dans le cadre de sa programmation Must-See TV, entre 2009 et 2014, avant de se terminer sur le service par contournement Yahoo! Screen, en 2015, permet de constater que Community est un objet télévisuel qui a constamment cherché à s’adapter à un média en pleine mutation. Son incapacité à survivre à l’instabilité secouant l’industrie télévisuelle, par l’entremise de la télévision traditionnelle et de la télévision en ligne, souligne ainsi que le passage de la télévision vers cette ère numérique est plus complexe qu’il ne paraît. / During the 2000s, the American televisual landscape was deeply shaken by the arrival of the Internet. The quick growth of digital technologies and the emergence of new types of media forced a reluctant television industry to change; be that in production, creation or reception. This transition from a pre-digital to a digital form of television was particularly difficult for the National Broadcasting Company (NBC). In the midst of this defining moment in American television history came Community (NBC, 2009-2014; Yahoo!Screen, 2015), a sitcom that embodied and reflected the various transformations brought by the convergence of the Internet and television, as well as the consequences this confluence bore to that industry. From being broadcast on NBC’s Must-See TV lineup between 2009 and 2014 to then moving to Yahoo!’s online platform in 2015, Community’s journey in television revealed its multiple attempts at adapting to a media in mutation. Therefore, the inability of the series to survive an unstable television industry through both traditional and online means underlines the complexity pertaining to television’s transition to a digital era.

Skolan ska genomsyras av ett jämställdhetsperspektiv. Granskningar visar dock att det finns brister i skolors jämställdhetsarbete och det finns en rad jämställdhetsproblem i skolan. Många av problemen kan kopplas till könsnormer, varför svenska skolmyndigheter förespråkar ett normmedvetet förhållningssätt. Samtidigt visar granskningar att lärare saknar kunskap om just normer. Syftet med studien är att undersöka normmedvetna grundskollärares uppfattningar om hur ett jämställdhetsperspektiv kan genomsyra undervisningen i enlighet med vad som beskrivs i läroplanen, för att bidra med verktyg för hur lärare kan arbeta med ett jämställdhetsperspektiv på undervisningen. Studien utgår från ett normkritiskt perspektiv och består av kvalitativa intervjuer med sex grundskollärare som uppfattar sig själva som normmedvetna. Resultatet visar flera sätt på vilka normmedvetna lärare beskriver att ett jämställdhetsperspektiv kan genomsyra undervisningen: strategier för att fördela talutrymmet jämställt, reflekterande frågor för att synliggöra egna föreställningar om kön, förslag på övningar för att kritiskt granska normer om kön och etnicitet, konkreta exempel på representation i undervisningsmaterial samt tankar om hur gruppindelning och varierade arbetssätt kan bidra till jämställdhet. Lärarna utgick ofta från ett intersektionellt perspektiv, men en del lärare saknade kunskap om hur olika normer påverkar varandra. Vidare identifieras flera dilemman med ett normmedvetet jämställdhetsarbete: att synliggöra könsskillnader utan att befästa olikheter mellan könen och att normmedvetenhet tycks förutsätta en vilja att kritiskt granska sig själv, något som bygger på intresse samtidigt som det är problematiskt om jämställdhetsfrågan ses som en intressefråga. Därutöver diskuteras dilemmat att konkretisera jämställdhetsuppdraget för att bidra med verktyg och samtidigt belysa risken med att mekanisera jämställdhetsuppdraget. / The school system should be permeated by a perspective of gender equality. However, studies have shown that there are shortcomings in the work being done for gender equality; and the lack of gender equality manifests itself in several issues. Many of these can be attributed to gender norms, which is why Swedish school authorities advocate a norm critical approach. Yet, surveys have shown that teachers are lacking knowledge of gender norms. The purpose of this study is to investigate the views of norm critical elementary school teachers on how a gender equality perspective could permeate teaching in accordance with what is prescribed in the curriculum, in order to provide tools for how teachers could work with gender equality in their teaching. The study is grounded in a norm critical perspective and consists of qualitative interviews with six elementary school teachers perceiving themselves to be norm critical. The results indicate several possible ways of establishing a permeating gender equality perspective on teaching: strategies for dividing the opportunity to speak gender equally; reflective questions for identifying your own notions of gender; suggestions of exercises for challenging norms about gender and ethnicity; practical examples of representation in teaching material as well as ideas about how grouping and varied ways of working can contribute to gender equality. Many teachers were grounded in an intersectional perspective, but some teachers lacked knowledge of how different norms affect each other. Furthermore, several dilemmas of a norm critical gender equality approach were identified: to make gender differences visible without consolidating differences between the genders, and that being norm critical seems to presuppose a willingness to critically question oneself. This willingness presupposes being interested in the topic, but portraying gender equality as a question of interest is problematic. Additionally, the dilemma of turning the gender equality commitment into a set of practical tools while also acknowledging the risk of mechanizing it is discussed.

The Dissertation titled Documentary Approaches in Contemporary Fine Art Moving Image focuses on the practical and theoretical research of documentary approaches to videos and films in the art field. It notices especially the self-reflexive strategies as a consequence of critical approach towards the medium itself and lack of belief in its ability to mediate reality or truth. Attempts to convey reality by audiovisual means are accompanied by the reflection of the way this happens. The Dissertation also reflects on the uncertain relation between the documentary and truth, which has been described in art by the artist and theoretician Hito Steyerl. The examined artworks were made in the period between the beginning of 21st century, when the documentary turn was reflected intensively, and the present time. The selection of examples was strongly influenced by the local study of Israeli art in The Video Archive of the Center for Contemporary Art in Tel Aviv. Motives of conflict, violence and trauma resonating in studied videos and films influenced further selection and analysis of the authors’ documentary methods from a different context. In the selected works I can see particularly various forms of alienation effects and self-reflexive approaches. Using these procedures the artists highlight the constructedness of the audiovisual work and the way it was produced. Recurring formal principles have been stated. Reenactment of real events, revealing the way the work was produced or the artist’s position in the production process; these strategies indicate the uncertain relationship between the documentary work and reality. In the frame of these tendencies also reevaluation of the observational documentary strategies as something seemingly opposite to self-reflexive strategies is reviewed. Theoretical outcomes are continuously accompanied by author’s own art projects concentrated around the form of documentary portrait and its (de)construction. They experiment with the formal principles analyzed on a theoretical level.

The dissertation thesis studies the extension of the context of the term model as a means of interpretation for Czech and Slovak post-conceptual works of art. Based on result of a historical excursion into the history of painting, sculpture and architecture, the thesis offers a new typology of a model which is exemplified on particular work of art of Czech and Slovak post-conceptual era in the first two decades of the 21st century. The historical part of the thesis concludes the following: model in the art is an emancipated form originating from different academic as well as layman discourse; emancipated model has a methaphorical layer and thus it reflects wide historical, cultural and social relations. The categories proposed include: a linear model, a physical model, a cognitive model and an immersive model. The linear model encompases the sketch themes and so-called visualization metaphors (graphs, charts, schemes, etc) and originates as a reaction to information saturation and complicated networks. The physical model is a form to architecture and hobby modelling, it is characterised by a simple, „sketchy“ structure reacting to social themes and individual and collective memory. The cognitive model points to the cognitive turn of the society, it evaluates the materialisation of mental space and explains the emancipated model as an open category. Finally, the immersive model interprets the medium of exhibition as a model form which is articulated by and artisitic manifesto or an architectural interference. Another form of immersion that is being discussed in the chapter about immersive models, is a photographic or 3 D computer illusion as a reaction to society‘s virtualisation. Simultaneously to theoretical-historical research, an artistic research was taking place which became the basis for the creation of different categories and typologies of model. Each proposed category thus includes a so-called author‘s note reflecting the practical part of the dissertation thesis.

Den här studien syftar till att söka förståelse för tatuerade personers individuella uppfattningar kring betydelsen av deras tatueringar, samt kring tatueringar på en generell nivå. Vidare har vi haft för avsikt att undersöka hur tatuerade personer upplever omgivningens uppfattningar och bemötande utifrån tatueringarna. Studien har en kvalitativ ansats med främst ett induktivt förhållningssätt, vilket emellertid även innefattar vissa deduktiva inslag. Vidare intar studien idealism och konstruktivism som ontologiska ståndpunkter med en hermeneutisk och interpretativistisk epistemologi. Insamlandet av empiriskt material har skett genom semistrukturerade intervjuer.   Resultat i studien visar att tatueringar utgör en betydande komponent i en individs identitetsskapande vilket samverkar med individens omgivning. Resultatet visar även att tatueringarna och dess symbolik kopplas till individens relation till omgivningen och dess roll som samhällsvarelse i vilken samhälleliga normer och uppfattningar tillägnas och tolkas. Slutligen visar resultatet att tatueringar och tatuerande som aktivitet kan återspegla det samtida samhället och dess utmärkande drag. / The aim of this study is to seek an understanding of the individual perceptions of tattooed persons about the significance of their tattoos, as well as of tattoos on a general level. Furthermore, we intended to investigate how tattooed people perceive the surroundings' perceptions and attitudes based on the tattoos. The study has a qualitative approach with mainly an inductive approach, which, however, also includes some deductive elements. Furthermore, the study adopts idealism and constructivism as ontological positions with a hermeneutic and interpretivist epistemology. The collection of empirical material has been done through semi-structured interviews. Results in the study show that tattoos are a significant component of an individual's creation of identity which interacts with the individual's surroundings. The result also shows that the tattoos and their symbolism are linked to the individual's relationship to the environment and its role as a social being in which societal norms and perceptions are assigned and interpreted. Finally, the results show that tattoos and tattoos as an activity can reflect the contemporary society and its distinctive features.

Der Zusammenhang von technischer Entwicklung und gesellschaftlicher Modernisierung wird mit Mitteln der systemtheoretischen Soziologie untersucht. Zu diesem Zweck werden die Konzepte "Technik" und "soziale Evolution" reformuliert. "Technik" ist ein spezieller Typ der Grenzbildung von Systemen, die Ereignisse ihrer Umwelt als kausal verknüpft beobachten; Technik wird demnach definiert als fixierte Erwartung, die sich auf kausal verknüpfte Umweltereignisse bezieht. "Soziale Evolution" ist der Typ des Strukturwandels von sozialen Systemen, der sich aus der Selektion und Restabilisierung von Strukturvariationen ergibt. Aus soziologischer Sicht ist jede technische Entwicklung als ein spezifischer Aspekt der sozialen Evolution zu verstehen. Dies wird mit der Konfrontation des Begriff des "Fortschritts" mit dem der "Modernisierung" gezeigt. Eine Gesellschaft versucht durch das Verwenden und das Beschränken von Technik über ihre eigene Evolution zu verfügen. Es erweist sich, daß diese Versuche zwar komplexer, aber nicht unbedingt erfolgreicher werden. Die einer jeden Evolution eigene Entwicklungsoffenheit kann nicht außer Kraft gesetzt werden, auch dann nicht, wenn eine Gesellschaft Evolutionstheorien entwickelt und reflexiv auf sich selbst anwendet. Anders als vormoderne Gesellschaften zeichnet sich die moderne Gesellschaft durch ihre hochgradig frei kontextualisierbare und damit riskante Technik aus. Kontextualisierungen und Entscheidungsnotwendigkeiten im Umgang mit moderner Technik bedingen Reflexivität. Technische Entwicklungen lassen Determinationen und Optionen in gleichem Maße wachsen. Komplex ist die soziale Seite von Technik, nicht die Kompliziertheit ihrer technischen Komponenten. Reflexive Technologiepolitik und Technikfolgenabschätzung sind gezwungen, die soziale Dynamik technischer Entwicklungen zu berücksichtigen. / There are several means to analyse the intrinsic connection of technological development and social evolution in sociology today. The thesis examines technology and its development as part of social evolution from a system-theoretical point of view. Using this approach, terms like "technology" and "social evolution" are reformulated. "Technology" is a particular type of border of social systems, using the mode of causality in observing its environment; thus Technology is defined as the fixation of causal expectations. "Social evolution" is a social systems' structural change by the selection and reinforcement of variations, creating a singular history. In terms of sociology, any technological development is part of a wider developing social context. This is visualized by confronting the terms "progress" and "modernization"; both being concepts of sociology as well as of debates on technology and social development. By using technology, by giving way to innovation, and by limiting the use of technology, a given society tries to monitor and influence its own evolution. The thesis shows that these attempts become more complex, but not necessarily more effective. The fundamental properties of any evolution cannot be annulated --- the social evolution always remains unpredictable, even when evolutionary theories allow reflexive observations. In contrast to its predecessors the modern society constitutes a type of technology which is highly independent of any given social context. But this freedom is risky. Contextualizations and decision-makings imply a higher degree of reflexivity. In the case of technological development, both determinations and options increase at the same time. What is complex in technological development is its social, not its mere technical side. Any reflexive debate on technology has to reflect technology as a social issue.

Ce mémoire, qui s’intéresse aux enjeux de l’imbrication du philosophique et du romanesque chez les penseurs des Lumières françaises, cherchera à mettre de l’avant la contribution originale de Denis Diderot à la réflexion philosophique sur le roman, de même qu’à l’exploration des ressources littéraires permettant de philosopher par le roman. Nous nous proposons, dans un premier temps, d’examiner ce qui relève d'une théorisation explicite de l'écriture des fictions narratives dans l’oeuvre du philosophe langrois. Nous nous attacherons à montrer comment l’approfondissement des thèses de son matérialisme, ainsi que les déceptions consécutives à ses projets de réforme du théâtre, sont venus bouleverser les conceptions esthétiques et morales qui formaient le premier horizon normatif à partir duquel Diderot envisageait les modalités idéales de l'écriture et de la réception romanesques. Puis, dans un deuxième temps, nous chercherons à faire voir comment Diderot, à titre d’auteur de fictions narratives, entreprend une exploration aussi originale que féconde des ressorts proprement philosophiques de l’écriture romanesque. Les dernières sections de notre étude seront consacrées à une lecture approfondie de Jacques le fataliste et son maître. Nous tâcherons d’abord d’en dégager les principales ressources mises au service de la formation d’un lecteur de romans plus lucide et plus critique. Puis, nous chercherons à mettre en lumière de quelle façon cette propédeutique, si elle réussit, doit ultimement conduire le lecteur à entamer un véritable dialogue avec l’oeuvre, tant sur les questions métaphysiques et ontologiques qu’entraîne le « fatalisme » de Jacques, que sur les enjeux moraux qui en découlent. / This thesis, which deals with the interweaving of philosophy and literature in the work of French Enlightenment thinkers, seeks to shed light on Denis Diderot’s unique contributions to philosophical reflection on the novel, as well as to the exploration of the literary resources that make it possible to delve into philosophical issues through the novel. Beginning with an examination of Diderot’s explicit theories about writing narrative fiction, it argues that the outgrowth of his materialism and the disenchantment following his attempts at theatre reform upended the aesthetic and moral basis for the initial normative framework underpinning his analysis of how fiction is ideally written and received. It goes on to examine how Diderot, as a novelist, undertook an innovative and fruitful exploration of the unsuspected philosophical resources that narrative fiction offers. The final sections are devoted to a close reading of Jacques the Fatalist and His Master, beginning with an attempt to identify the main resources it deploys to train more lucid and critical readers of fiction. The thesis then seeks to show how this knowledge base, if successfully transmitted, ultimately leads the reader to engage in a genuine dialogue with the work, both in terms of the metaphysical and ontological issues raised by Jacques’ “fatalism” and the moral issues that ensue.
