La présente étude, faisant objet d’une thèse de doctorat, a trait à l’étude des expressions idiomatiques en lien avec la représentation spatiale en italien. Ce travail a pour objectif d’étudier et d’analyser ces expressions idiomatiques dans la langue italienne, en nous intéressant aux implications que cela peut avoir sur la représentation de l’espace en italien. L’étude que nous nous proposons de mener a pour objet la compréhension de ces structures figées en italien et de leurs équivalents en français. L’analyse des effets des expressions idiomatiques dans le discours du langage quotidien, rendue possible par l’élaboration d’un corpus de 25 romans graphiques, a été l’occasion de mieux comprendre la productivité de ces locutions figées. / This study as a doctoral thesis, deals with the analysis of the idiomatic expressions and spatial reference in the Italian and French languages. This research was aimed at describing the meanings of an idiom's element that plays important role in idiom interpretation and use, by raising the question of various non-literal forms evolves with a particular context as graphic novels. This work focuses on a systemic analysis of idiom types, the evidence relating to one major classes of idiom comprehension models: non-composition models, which assume the compositional meanings of phrases and sentences are routinely generated and used in the development of 25 graphic novels; the items are considered as one opportunity to better understand the structure of the idiom.

<p>Successful navigation requires an accurate mental spatial representation of the environment that can be updated during movement. Experiments with animals and humans have demonstrated the existence of two forms of spatial representation: egocentric (observer-centered) and allocentric (environment-centered). Unfortunately, specifically how humans use these two systems is not well understood. The current dissertation was focused on providing evidence differentiating human use of egocentric and allocentric spatial reference frames, specifically examining the characteristics and contributions from body-based sources. Two empirical chapters are presented that include experiments involving two common spatial tasks. In Chapter 2, updating of feature relations within a room-sized environment was examined by having observers provide directional judgments to learned features with respect to an imagined orientation that was either congruent or incongruent with their physical orientation. The information available for updating the physical orientation was manipulated across experiments. Performance differences between congruent and incongruent conditions demonstrated the reliance on egocentric representations for updating, and differentiated body- and knowledge-based components of the egocentric updating process. The specificity of the body-based component was examined in Chapter 3 by having observers detect changes made to a tabletop spatial scene following a viewpoint shift resulting from their movement, scene rotation or both. The relation between the extent of observer movement and the magnitude of the experienced viewpoint shift was manipulated. Change detection performance was best when the extent of observer movement most closely matched the viewpoint shift, and declined as the match declined. Thus, body-based cues contributed specific information for updating self-to-feature relations that facilitated scene recognition. Throughout the course of the research program it has become clear that humans rely on egocentric representations to complete these tasks, and sensory and motor modalities involved in self-motion are integrated for updating spatial relations of novel environments.</p> / Doctor of Philosophy (PhD)

<p>When an observer detects changes in a scene from a viewpoint that is different from the learned viewpoint, viewpoint change caused by observer’s locomotion would lead to better recognition performance compared to a situation where the viewpoint change is caused by equivalent movement of the scene. While such benefit of observer locomotion could be caused by spatial updating through body-based information (Simons and Wang 1998), or knowledge of change of reference direction gained through locomotion (Mou et al, 2009). The effect of such reference direction information have been demonstrated through the effect of a visual cue (e.g., a chopstick) presented during the testing phase indicating the original learning viewpoint (Mou et al, 2009).</p> <p>In the current study, we re-examined the mechanisms of such benefit of observer locomotion. Six experiments were performed using a similar change detection paradigm. Experiment 1 & 2 adopted the design as that in Mou et al. (2009). The results were inconsistent with the results from Mou et al (2009) in that even with the visual indicator, the performance (accuracy and response time) in the table rotation condition was still significantly worse than that in the observer locomotion condition. In Experiments 3-5, we compared performance in the normal walking condition with conditions where the body-based information may not be reliable (disorientation or walking over a long path). The results again showed a lack of benefit with the visual indicator. Experiment 6 introduced a more salient and intrinsic reference direction: coherent object orientations. Unlike the previous experiments, performance in the scene rotation condition was similar to that in the observer locomotion condition.</p> <p>Overall we showed that the body-based information in observer locomotion may be the most prominent information. The knowledge of the reference direction could be useful but might only be effective in limited scenarios such as a scene with a dominant orientation.</p> / Master of Science (MSc)

Das Ziel der Dissertation ist, den Gebrauch von sekundären Raumdeixes (‚vor‘, ‚hinter‘, ‚rechts / links von‘) und Referenzrahmen (absolut, intrinsisch, relativ) von deutschen, englischen, italienischen und polnischen Muttersparcher_innen für die Beschreibung von statischen Raumrelationen zu untersuchen. Zwei Experimente pro Sprache wurden durchgeführt. Das erste Experiment untersuchte Seitenzuweisung. Die Proband_innen sahen ein Objekt von der Vorderseite (kanonische Position) und Rückseite (nicht-kanonische Position). Das Ergebnis bestätigt, dass die Proband_innen der vier Sprachen die Außenperspektive für die Seitenzuweisung des kanonisch stehenden vis-à-vis Objektes meistens benutzen. Einige Variationen haben die Pol_innen und Italiener_innen gezeigt, vor allem bei der Zuweisung von der rechten und linken Seite. Dabei wiesen die Deutschen und Italiener_innen signifikante Unterschiede auf. Mit dem Mouse Tracking habe ich die Interpretation von statischen Raumrelationen von zwei Komplexitätsgraden untersucht. Die einfachen Raumrelationen enthielten entweder ein extrinsisches oder intrinsisches Referenzobjekt (belebt; unbelebt) und eine Flasche als lokalisiertes Objekt. Die komplexeren Raumrelationen wurden um einen Agenten ergänzt und mit der indirekten Rede eingebettet. Das erlaubte die Erforschung von Origo-Shift. In allen Raumrelationen wurden die Proband_innen gebeten, die Lokalisation von der Flasche zu beschreiben. Die Deutschen und Italiener_innen zeigten signifikante Unterschiede bei der Interpretation von einfachen belebten und unbelebten intrinsischen Raumrelationen. Bei der Interpretation von komplexeren intrinsischen Raumrelationen haben die polnischen Muttersprachler_innen die Origo am häufigsten zum Agenten verschoben und von seinem Blickwinkel bezüglich des relativen Bezugsrahmens die Relationen beschrieben. Im Allgemeinen, für die Interpretation von komplexeren Raumrelationen ist die Wahl des intrinsischen Bezugsrahmens im Vergleich zu einfacheren Raumrelationen signifikant gesunken. Das heißt, die meisten Proband_innen haben die Origo zum Agenten verschoben und von seinem Blickwinkel die Raumrelationen bezüglich der Spiegelstrategie interpretiert. / The aim of this dissertation is to investigate the use of reference frames (absolute, relative, intrinsic) and secondary local deixes (‘in front of’, ‘behind’, ‘to the right / left of’) by German, English, Italian, and Polish native speakers to describe static spatial relations. Two experiments per language were carried out. The first experiment investigated side assignment. Participants saw the object from the front (the canonical position) and the back (the noncanonical position). The results confirm that for side assignments to a canonical positioned vis-à-vis object most speakers of the four languages use the outside perspective. However, some variations occurred for Polish and Italian, especially while identifying the right and left sides showing significant differences between German and Italian. Using mouse tracking, I tested the interpretation of static spatial relations of two kinds of complexity. The simple spatial relations included either extrinsic or intrinsic reference objects (animate; inanimate) and a bottle as localized object. The complex spatial relations were supplemented by an agent and embedded by indirect speech. This allows the investigation of origo shift. In all situations, participants were asked to describe the location of the bottle. German and Italian showed significant differences in interpreting simple animate and inanimate intrinsic relations. Interpreting the intrinsic complex relations, Polish speakers shifted the origo to the agent most frequently and described the relations from his point of view. All in all, for the complex relations, the choice of the intrinsic reference frame decreased significantly compared to the simple relations. That is, most participants shifted the origo to agents’ point of view and interpreted the spatial relations applying the reflection strategy.

Les maladies infectieuses représentent aujourd’hui un problème majeur de santé publique. Devant l’augmentation des résistances bactériennes, l’émergence de nouveaux pathogènes et la propagation rapide de l’épidémie, le suivi et la surveillance de la transmission de la maladie devient particulièrement importants. Face à une telle menace, la société doit se préparer à l'avance pour réagir rapidement et efficacement si une telle épidémie est déclarée. Cela nécessite une mise en place des dispositifs de suivi et de prévention. Dans ce contexte, nous nous intéressons, dans le présent travail, à l’élaboration d’un Système d’Information Décisionnel Spatio-temporel pour le suivi et la surveillance du phénomène de propagation de l’épidémie de la grippe saisonnière au sein de la population de la ville d’Oran (Algérie). L’objectif de ce système est double : il consiste, d’une part, à comprendre comment l’épidémie se propage par l’utilisation du réseau social Small World (SW) et du modèle à compartiments d’épidémie SEIR (Susceptible-Exposed-Infected-Removed), et d’autre part, à stocker dans un entrepôt les données multiples tout en les analysant par un outil d’analyse en ligne de donnée Spatiale dit SOLAP (Spatial On-Line Analytical Processing). / Today, infectious diseases represent a major public health problem. With the increase of bacterial resistance, the emergence of new pathogens and the rapid spread of epidemic, monitoring and surveillance of disease transmission becomes important. In the face of such a threat, the society must prepare in advance to respond quickly and effectively if an outbreak is declared. This requires setting up monitoring mechanisms and prevention.In this context, we are particularly interested by development a Spatiotemporal decision support system for monitoring and preventing the phenomenon of seasonal influenza epidemic spread in the population of Oran (city at Algeria).The objective of this system is twofold: on one hand, to understand how epidemic is spreading through the social network by using SEIR (Susceptible-Exposed-Infected-Removed) compartmental model within Small World network, and on the other hand, to store multiple data in data warehouse and analyzing it by a specific online analysis tool Spatial OLAP (Spatial on-line Analytical Processing).
