Poïétique de la création sonore au cinéma : la figure de l’artiste-poïéticien

Nous proposons, dans ce mémoire, d’explorer les possibilités pratiques et pédagogiques d’une approche autopoïétique de la création sonore au cinéma. Notre principal souci sera de saisir les modalités de l’ascèse propre aux artistes qui se livrent à une telle activité, comprise comme un « apprentissage de soi par soi » (Foucault), afin de faire celui qui peut faire l’œuvre (processus de subjectivation), et le rôle descriptif et opératoire de cet exercice - en tant qu’effort pour penser de façon critique son propre savoir-faire -, dans le faire-œuvre et l’invention de possibles dans l’écriture audio-visuelle cinématographique. Pour ce faire, d’une part, nous étudierons, à partir de témoignages autopoïétiques, le rapport réflexif de trois créateurs sonores à leur pratique et leur effort pour penser (et mettre en place) les conditions d’une pratique et d’une esthétique du son filmique comme forme d’art sonore dans un contexte audio-visuel, alors qu’ils travaillent dans un cadre normalisant : Randy Thom, Walter Murch et Franck Warner. D’autre part, nous recourrons à différentes considérations théoriques (la théorie de l’art chez Deleuze et Guattari, la « surécoute » chez Szendy, l’histoire de la poïétique à partir de Valéry, etc.) et pratiques (la recherche musicale chez Schaeffer, la relation maître-apprenti, les rapports entre automatisme et pensée dans le cinéma moderne chez Artaud et Godard, etc.), afin de contextualiser et d’analyser ces expériences de création, avec l’objectif de problématiser la figure de l’artiste-poïéticien sur un plan éthique dans le sillage de la théorie des techniques de soi chez Foucault.

Effects of modality, urgency and situation on responses to multimodal warnings for drivers

Signifying road-related events with warnings can be highly beneficial, especially when imminent attention is needed. This thesis describes how modality, urgency and situation can influence driver responses to multimodal displays used as warnings. These displays utilise all combinations of audio, visual and tactile modalities, reflecting different urgency levels. In this way, a new rich set of cues is designed, conveying information multimodally, to enhance reactions during driving, which is a highly visual task. The importance of the signified events to driving is reflected in the warnings, and safety-critical or non-critical situations are communicated through the cues. Novel warning designs are considered, using both abstract displays, with no semantic association to the signified event, and language-based ones, using speech. These two cue designs are compared, to discover their strengths and weaknesses as car alerts. The situations in which the new cues are delivered are varied, by simulating both critical and non-critical events and both manual and autonomous car scenarios. A novel set of guidelines for using multimodal driver displays is finally provided, considering the modalities utilised, the urgency signified, and the situation simulated.

Humor político audiovisual en Colombia: de los gloriosos años noventa en televisión a internet como alternativa

El humor político alrededor del mundo ha sido un recurso para criticar el poder y la esfera política con la mordacidad que otros escenarios no permiten y con lenguajes que generan empatía con el público. En la capacidad de criticar a todos los poderes –y poderosos- por igual, sin condescendencias, recae la credibilidad de esa crítica, la cual se debe poder hacer sin censura en una sociedad pluralista y democrática. En Colombia, el humor político en televisión emergió y vivió su época dorada en la década de los noventa, hasta que su principal exponente, Jaime Garzón, fue asesinado. Este trabajo de grado buscó indagar por qué, a pesar de que nuevos productos de crítica política con humor surgieron en el país, hoy no hay ese tipo de oferta en la televisión abierta nacional. La respuesta a ese interrogante se pudo encontrar en múltiples factores, como un nuevo modelo económico en la industria de la televisión, un ambiente político polarizado y la ausencia o falta de promoción de talentos detrás de los libretos. Asimismo, en medio de esta coyuntura, se plantea que internet ha sido un vehículo para expresar, incluso de manera anónima, lo que miembros de la sociedad creen que anda mal con el poder y la política.

El grito de Calibán. Del cinematógrafo al proyecto teleSur: la construcción de lo latinoamericano en la comunicación audiovisual regional

This essay analyzes on the importance of TeleSur TV Station (founded in 2005), in the historical context of the development of audio-visual means of communication in Latin America, as well as the debates about the influence of mass media in the process of cultural identity raising-up. It proposes the thesis that the project of Tele- Sur plays a key role in the shaping of a new international order on communication that allows the protection of the cultural diversity of Latin American nations and democratizes the world’s information flows in the neoliberal globalization stage.

In Your Face! Investigating Facework, Criticism, and Humour with Corpora in Electoral Debates

In political debates, the media[tisation] can determine the use of language with the aim to increase their spectacularisation and polarisation, possibly by means of criticism and humour, respectively. These linguistic strategies are often used in order to shape what was defined by Goffman as one’s face. Politicians, in particular, can recur to facework in a double sense: shaping their own face positively and/or that of their opponents negatively. Starting from the sociologic theory of face by Goffman and Levinson, with the help of corpus analysis tools, this research investigated the ways in which various forms of criticism and forms of humour were conducted in 3 electoral debates on a national scale (Germany, Ireland, and New Zealand) and 1 debate for the municipal election in Rome. The transcripts were revised after automatic transcriptions were extracted or found online, of which the audio-visual content is available on the Internet. The CADS research aimed to investigate the role that criticism and humour played within each participant’s discourse, and to identify differences and similarities among the strategies used by political leaders and moderators in different countries, and in different cultural, political, and media contexts.

Experimental and numerical characterization of flame instability in hydrogen-containing flames

In the framework of the energy transition, the acquisition of proper knowledge of fundamental aspects characterizing the use of alternative fuels is paramount as well as the development of optimized know-how and technologies. In this sense, the use of hydrogen has been indicated as a promising route for decarbonization at the end-users stage in the energy supply chain. However, the elevated reactivity and the low-density at atmospheric conditions of hydrogen pose new challenges. Among the others, the dilution of hydrogen with carbon dioxide from carbon capture and storage systems represents a possible route. However, the interactions between these species have been poorly studied so far. For these reasons, this thesis, in collaboration between the University of Bologna and Technische Universität Bergakademie of Freiberg in Saxony (Germany), investigates the laminar flame of hydrogen-based premixed gas with the dilution of carbon dioxide. An experimental system, called a heat flux burner, was adopted ad different operating conditions. The presence of the cellularity phenomenon, forming the so-called cellular flame, was observed and analysed. Theoretical and visual methods have allowed for the characterization of the investigated flames, opening new alternatives for sustainable energy production via hydrogen transformation.

Methods for automatic and assisted image annotation

Personal memories composed of digital pictures are very popular at the moment. To retrieve these media items annotation is required. During the last years, several approaches have been proposed in order to overcome the image annotation problem. This paper presents our proposals to address this problem. Automatic and semi-automatic learning methods for semantic concepts are presented. The automatic method is based on semantic concepts estimated using visual content, context metadata and audio information. The semi-automatic method is based on results provided by a computer game. The paper describes our proposals and presents their evaluations.

Expert opinion on best practice guidelines and competency framework for visual screening in children

PURPOSE: Screening programs to detect visual abnormalities in children vary among countries. The aim of this study is to describe experts' perception of best practice guidelines and competency framework for visual screening in children. METHODS: A qualitative focus group technique was applied during the Portuguese national orthoptic congress to obtain the perception of an expert panel of 5 orthoptists and 2 ophthalmologists with experience in visual screening for children (mean age 53.43 years, SD ± 9.40). The panel received in advance a script with the description of three tuning competencies dimensions (instrumental, systemic, and interpersonal) for visual screening. The session was recorded in video and audio. Qualitative data were analyzed using a categorical technique. RESULTS: According to experts' views, six tests (35.29%) have to be included in a visual screening: distance visual acuity test, cover test, bi-prism or 4/6(Δ) prism, fusion, ocular movements, and refraction. Screening should be performed according to the child age before and after 3 years of age (17.65%). The expert panel highlighted the influence of the professional experience in the application of a screening protocol (23.53%). They also showed concern about the false negatives control (23.53%). Instrumental competencies were the most cited (54.09%), followed by interpersonal (29.51%) and systemic (16.4%). CONCLUSIONS: Orthoptists should have professional experience before starting to apply a screening protocol. False negative results are a concern that has to be more thoroughly investigated. The proposed framework focuses on core competencies highlighted by the expert panel. Competencies programs could be important do develop better screening programs.

Combining sparse and dense methods in 6D Visual Odometry

Exploration of the visual system : Part 2. In vivo analysis methods : virtual-reality optomotor system, fundus examination and fluorescent angiography

The mouse has emerged as an animal model for many diseases. At IRO, we have used this animal to understand the development of many eye diseases and treatment of some of them. Precise evaluation of vision is a prerequisite for both these approaches. In this unit we describe three ways to measure vision: testing the optokinetic response, and evaluating the fundus by direct observation and by fluorescent angiography.

Reproducibility of species lists, visual cover estimates and frequency methods for recording high mountain vegetation

Question: When multiple observers record the same spatial units of alpine vegetation, how much variation is there in the records and what are the consequences of this variation for monitoring schemes to detect change? Location: One test summit in Switzerland (Alps) and one test summit in Scotland (Cairngorm Mountains). Method: Eight observers used the GLORIA protocols for species composition and visual cover estimates in percent on large summit sections (>100 m2) and species composition and frequency in nested quadrats (1 m2). Results: The multiple records from the same spatial unit for species composition and species cover showed considerable variation in the two countries. Estimates of pseudoturnover of composition and coefficients of variation of cover estimates for vascular plant species in 1m x 1m quadrats showed less variation than in previously published reports whereas our results in larger sections were broadly in line with previous reports. In Scotland, estimates for bryophytes and lichens were more variable than for vascular plants. Conclusions: Statistical power calculations indicated that, unless large numbers of plots were used, changes in cover or frequency were only likely to be detected for abundant species (exceeding 10% cover) or if relative changes were large (50% or more). Lower variation could be reached with the point methods and with larger numbers of small plots. However, as summits often strongly differ from each other, supplementary summits cannot be considered as a way of increasing statistical power without introducing a supplementary component of variance into the analysis and hence the power calculations.
