This thesis argues for poietic hermeneutics as a work of gathering and re-siting which intervenes in the local material-discursive site. This is an interruptive tactic of the local church, seeking the flourishing of here through transitory, non-hegemonic acts of re-making. In developing this tactic I draw a critique of a practical theology discourse which, I argue, masks acts of making, with a consequent loss of attentiveness to materiality and a normative commitment to the development of practices internal to the church and the practitioner.

L’innovation du lieu hospitalier intéresse le domaine de conception et de création dans une lecture et une démarche esthétique et poïétique. Cette recherche vise à alimenter des réflexions en esthétique et en poïétique, par le biais des interrogations sur la couleur et la lumière. La démarche conceptuelle s’achève par un va-et-vient entre pratique et théorie, entre sensibilité et système nerveux, entre complexité et simplicité. Je cherche à travers cette recherche, à trouver une autre identité aux espaces sanitaires en Tunisie, respectant à la fois, les exigences technico médicales et l’identité patrimoniale. Je pose les problématiques de la démarche et de la méthodologie, de la réflexion et de la lecture, du théorique et d’empirique. Les différentes parties de cette recherche doctorale portent sur la relation entre conceptions couleur et lumière et certaines interrogations en matière de poïétique et d’esthétique. / Innovation hospital design interested field and creation in reading and aesthetic and poietic approach. This research aims to contribute to reflections on aesthetics and poietics, through questions about color and light. The conceptual approach ends with a back and forth between theory and practice, between sensitivity and nervous system, between complexity and simplicity. I'm looking through this research, to find another identity sanitary spaces Tunisia, respecting both the technical requirements and medical heritage identity. I put the problems of the approach and methodology, reflection and reading, the theoretical and empirical. The different parts of this doctoral research focuses on the relationship between color and light designs and some questions for poietic and aesthetic.

Cette recherche s’interroge sur les rapports entre consommation et communication dans les cafés et lessupermarchés. Ces espaces nous les avons qualifié d’interstitiels car ils correspondent à un entre-Deux signifiantdans la vie sociale. On a pu montrer que l’espace se construit à travers les praxis et les imaginaires, qui sepositionnent face aux normes qui en régissent les usages. Aux structures plastiques des espaces correspondentdes négociations qui permettent aux identités sociales de se construire. Cohabitent ainsi quatre dimensions dansles espaces interstitiels : la dimension inter de l’entre-Deux qui articule l’individu à la communauté, la dimensionhyper qui est celle des normes structurants les échanges, la dimension infra qui permet la négociation et enfin ladimension micro qui implique la fabrication des identités sociales et la posture de chercheur adoptée dans cetravail.Cette recherche est aussi l’occasion de présenter une méthode, dénommée microsic, qui se veut une démarcheavec une base ethnographique permettant de déployer des méthodologies à même de capter des situationssociales de nature instables. Nous avons insisté sur la dimension poïétique de toute recherche en anthropologiede la communication, dont la visée est de rendre compte de phénomène qui se dérobent en permanence auregard et dont il faut restituer la complexité. / This research questions the relationship between consumption and communication in cafes and supermarkets.We have termed these spaces interstitial because they correspond to a meaning of an in-Between found insocial life. It has been shown that space is built through the praxis and the imaginary, which position themselvesfacing the standards that govern the practices. To the visual structures of the spaces correspond negotiationsthat enable the building of social identities. Thus four dimensions coexist in the interstitial spaces : the in-Betweeninter dimension that links the individual to the community, the hyper dimension which is the one of the standardsthat structure exchanges, the infra dimension that enables negotiation and finally the micro dimension thatinvolves the making of social identities and the researcher posture adopted in this work.This research is also an opportunity to present a method, called microCs, that aims to be an approach with anethnographic basis enabling the deployment of the appropriate methodologies for capturing inherently unstablesocial situations. We emphasized the poietic dimension of any research in anthropology of communication,whose aim is to account for phenomena that constantly avoid attention and whose complexity we must bring out.

Notre mémoire de recherche-création a pour point de départ deux conceptions sonores filmiques, auxquelles nous avons contribué en tant que monteur et concepteur sonores. Ces films – et leur bande sonore – ont, par leur forme, leur contenu, mais aussi par la dynamique ayant rythmé leur création, redéfini un aspect ou un autre de notre pratique. Ainsi, au moyen d'une auto-poïétique, nous explorons les différentes conditions de la création sonore mises en jeu, qu'elles soient d'ordre technique – le film Saint-Denys Garneau – ou d'ordre esthétique – le film Ma famille en 17 bobines. Dans chaque cas, nous cherchons aussi à explorer les problèmes poétiques et pratiques posés. Au creux de cette conjugaison de ces conditions émergent alors des outils de médiation, des relations humaines, des mouvements esthétiques et des postures d'écoute qui jettent un éclairage inédit sur notre pratique sonore. / This research-creation project finds its roots in two film sound designs to which I contributed as a sound editor or sound designer. These films – and their respective soundtracks –, by their form, their content, but also by the dynamics that pulsed their creation, have redefined certain aspects of my own sound work. In this study, by the means of an autopoietic analysis, I explore the creative conditions at play in the elaboration of my sound designs, as they answer to technical matters – the film Saint- Denys Garneau – or aesthetic matters – the film Ma famille en 17 bobines. In each case, I also seek to deepen poetic and practical problems. From deep in the combination of these conditions emerge mediation tools, human relations, aesthetic movements and modes of listening that shed new light on my sound practice.

L’élaboration de ce travail de thèse s’inscrit dans une démarche universitaire, elle est également pensée de manière simultanée avec la création artistique. Elle s’oriente vers des questionnements liés à une quête personnelle, intime, mais également « traquée » dans une voie plus large qui est celle de la généalogie, de la photographie de famille, de l’image documentaire et des zones d’ombres qui font partie de toute histoire personnelle. Des mécanismes de résistance à l’artification se déploient comme tentative de réponse artistique et de recherche, face à une histoire mutique, un manque de paroles. L’histoire familiale est source de filiations plurielles, de transmissions – verbales ou non –, mais aussi de secrets. Certains vides apparaissent parfois dans des portraits où l’élément absent, par l’insistance de son manque dans la logique du récit, devient obsédant. La spécificité pour les artistes qui s’attachent à ces corpus consiste à collecter, s’approprier et exposer ces images troubles pour les réinvestir dans un circuit artistique, volubile et efficace. Ces nouvelles images, définies comme histoires intimes mais aussi comme un art du témoignage, se transforment alors en une mémoire collective : par un habile téléscopage de sens, l’oeuvre ainsi née de l’image vernaculaire fait irruption par sa plasticité et offre un sens nouveau à la figure effacée ou absente. Cette réflexion théorique et artistique, entreprise sur les relations polysémiques entre photographie documentaire et poïétique de l’effacement, analyse la manière dont l’art agit au coeur des images d’archives. Qu’est-ce qui de l’art– par ses méthodes, ses dispositifs de mise en oeuvre, son inscription sociale et historique–se trouve activé qui permette ainsi de « lire » une image qui refusait de se donner. Réciproquement, quels leviers sont élaborés par les artistes, pour mettre à jour des images qui ne leur appartiennent pas et qui viennent bouleverser notre rapport à l’information initiale ? C’est là tout l’enjeu de cette recherche théorique et plastique qui permet de saisir une mécanique d’artification des images d’archives, à mi-chemin de l’histoire intime et de la mythologie artistique ; ou comment du récit en creux surgissent des images, figures vacillantes entre présence et absence, archives d’un devenir reformulé. / The development of this thesis work falls within an academic approach, andis also simultaneously thought in connection with the artistic creation. It deals with personal and private questioning, but is also « hunted » in a different way regarding yet genealogy, family and documentary pictures and the shadow zones that are part of all personal history. Mechanisms of resistance to arti- fication are deployed as an attempt at an artistic and theoretical response, facing a mute story, a lack of words. The family history is the origin of plural filiations, transmissions–with or without words–but also secrets. Sometimes some empty spaces appear on portraits. The missing element, thus, becomes an obsession due to its lack in the logic of the story. The artists working on those corpuses specifically aim to collect, reclaim and exhibit those blurred pictures in order to re-use them into an artistic, voluble and efficient circuit. These new pictures–private stories and testimony art at once–turn into a collective memory : by a clever telescope of meaning, the work, born out of the vernacular image, breaks through thanks to its plasticity, and offers a new meaning to the erased or absent figure. This theoretical and artistic reflection, based on the polysemous relations between documentary pictures and « erasing poietic », analyses the way that art acts into old archive pictures. How can art give the power to « read » a picture that is invisible ? Which ways, implemented devices, social and histo- ric beliefs allow it ? Conversely, what levers are developed by the artists, to update images that do not belong to them and that change our vision of the initial information ? Here is the challenge of this theoretical and plastic research that let us understand a mechanism of the artifying archival image, midway between private story and artistic mythology ; or how can images or vacilla- ting figures between presence and absence appear from invisible elements, as archives of a reformulated future.

Esta dissertação apresenta a análise de oito produções artísticas contemporâneas que utilizam percursos urbanos como parte constitutiva essencial de suas poiéticas e poéticas. A partir do estudo das modificações espaço-temporais, desde o período industrial, assim como da forma como se estruturaram os deslocamentos no espaço urbano e os novos sentidos que estes adquiriram na atualidade, buscamos compreender os motivos pelos quais a poiética dos percursos persiste até hoje. Verificamos como os artistas contemporâneos, através de seus deslocamentos ou da apropriação das trajetórias de terceiros, ressignificaram os espaços urbanos e os personagens que neles interagem e, a partir dos percursos, teceram novos olhares sobre essa problemática na arte contemporânea. / This dissertation presents the analysis of eight art works by different contemporary artists who utilize urban routes as a constitutive part of their poietics and poetics. By studying spatial and temporal changes since the industrial period, as well as how urban spatial displacements and their present acquired meanings are structured, we seek to comprehend for what motives a poietic of urban routes should persist today. We have noted how contemporary artists have re-signified urban spaces and the people who interact with them by means of their displacements or the appropriation of other people’s daily routes, and, by using routes, they have developed new gazes in relation to these questions of contemporary art.
