The influence of parent's body mass index on peer selection: An experimental approach using virtual reality

Relatively little is known about the influence of psychosocial factors, such as familial role modeling and social network on the development and maintenance of childhood obesity. We investigated peer se- lection using an immersive virtual reality environment. In a virtual schoolyard, children were confronted with normal weight and overweight avatars either eating or playing. Fifty-seven children aged 7–13 participated. Interpersonal distance to the avatars, child's BMI, self-perception, eating behavior and parental BMI were assessed. Parental BMI was the strongest predictor for the children's minimal distance to the avatars. Specifically, a higher mothers' BMI was associated with greater interpersonal distance and children approached closer to overweight eating avatars. A higher father's BMI was associated with a lower interpersonal distance to the avatars. These children approached normal weight playing and overweight eating avatar peers closest. The importance of parental BMI for the child's social approach/ avoidance behavior can be explained through social modeling mechanisms. Differential effects of pa- ternal and maternal BMI might be due to gender specific beauty ideals. Interventions to promote social interaction with peer groups could foster weight stabilization or weight loss in children.

Putting Up a Big Front: Car Design and Size Affect Road-Crossing Behaviour

Previous research suggests that people tend to see faces in car fronts and that they attribute personality characteristics to car faces. In the present study we investigated whether car design influences pedestrian road-crossing behaviour. An immersive virtual reality environment with a zebra crossing scenario was used to determine a) whether the minimum accepted distance for crossing the street is larger for cars with a dominant appearance than for cars with a friendly appearance and b) whether the speed of dominant-looking cars is overestimated as compared to friendly-looking cars. Participants completed both tasks while either standing on the pavement or on the centre island. We found that people started to cross the road later in front of friendly-looking low-power cars compared to dominant-looking high-power cars, but only if the cars were relatively large in size. For small cars we found no effect of power. The speed of smaller cars was estimated to be higher compared to large cars (size-speed bias). Furthermore, there was an effect of starting position: From the centre island, participants entered the road significantly later (i. e. closer to the approaching car) and left the road later than when starting from the pavement. Similarly, the speed of the cars was estimated significantly lower when standing on the centre island compared to the pavement. To our knowledge, this is the first study to show that car fronts elicit responses on a behavioural level.

Le collectif contrarié : analyse des manifestations du sujet national et de sa remise en cause dans l'oeuvre de Robert Morin

La nation s’est affirmée à partir de la fin du 18e siècle comme l’un des grands paramètres de la modernité. Sa remise en cause, tout spécialement dans les dernières décennies du siècle dernier, est à la fois partie prenante et symptomatique de l’actuel phénomène d’effritement des identités collectives. Le Québec n’échappe pas à ce courant de fond, comme en témoigne l’œuvre du vidéaste et cinéaste Robert Morin, qui propose une galerie de personnages en manque d’attaches et souvent réduits à leur propre subjectivité. Dans un contexte de questionnement généralisé des concepts de nation et de collectivité, ces individualités se sentent isolées et tentent désespérément de réactualiser les liens qui les unissent à leurs semblables, mais sans grand succès. La communauté revêt ainsi une dimension nostalgique, parcourant l’œuvre de Morin dans son entièreté et se manifestant de différentes manières, tant à l’écran qu’à travers son approche du médium qui reste grandement tributaire des pratiques filmiques et vidéographiques des années ’60 et ’70. Écartelé entre la prise de conscience de son isolement et son désir d’appartenir à une entité collective, qu’elle soit nationale ou autre, le sujet délié que l’on retrouve chez Morin, comme cette thèse tente de le démontrer, subit ce phénomène de déliaison et lutte simultanément pour l’enrayer.

Agents et modèles de l'adaptation publicitaire en agence de communication marketing

L’industrie de la publicité doit se renouveler sans cesse pour suivre la réalité en constante évolution des entreprises et de leurs consommateurs, afin de produire des messages qui toucheront, séduiront, puis convaincront les publics visés. Différents facteurs socioéconomiques, politiques mais également technologiques incitent les annonceurs à orchestrer de vastes campagnes multilingues et multiculturelles, où est présentée une idée unique, conforme à l’identité de la marque, qui sera adaptée dans différents marchés. Il s’agit d’une stratégie très différente de celle de la création de campagnes propres à chaque culture, par des agences locales. Le choix de l’adaptation, motivé par des raisons économiques bien sûr, mais également stratégiques, entraîne une évolution de la perception de l’acte traduisant et de ses acteurs au sein du milieu du marketing et de la publicité. Alors que nous assistons à un rapprochement des industries du marketing et de la traduction, principalement dans les marchés secondaires comme le Québec, ce projet doctoral propose une réflexion traductologique sur la place que peut occuper l’adaptation dans une stratégie en publicité marketing, et sur les différentes fonctions que peut remplir un traducteur intégré à une équipe de spécialistes de la communication. Par ailleurs, de la réception du mandat d’adaptation à l’agence de marketing jusqu’à la diffusion du message dans la culture cible, nous explorons dans notre travail les différentes avenues que peut prendre le processus d’adaptation publicitaire. Cette thèse par articles comprend six publications en traductologie, publiées ou acceptées par des comités scientifiques, qui étudient la question de l’adaptation publicitaire sous un angle traductologique, mais ce travail multidisciplinaire s’inspire aussi des contributions des experts des études sur l’adaptation, la culture ainsi que la communication publicitaire. D’abord, le premier chapitre définit les notions de traduction, d’adaptation et d’appropriation auxquelles nous référerons tout au long de la thèse, et les situe dans le contexte de la communication promotionnelle internationale, notamment. Le deuxième chapitre dresse un portrait pratique et théorique de l’adaptation publicitaire, et porte sur les relations de travail entre le traducteur et les autres professionnels de l’agence. Nous y énumérons notamment les raisons de la progression du marché mondial de l’adaptation, comparativement à celui des multiples créations locales. Ensuite, le chapitre 3 définit les défis variés de l’adaptation publicitaire, et en présente une classification inspirée par la taxonomie de la théorie fonctionnaliste en traductologie, formée de quatre problèmes et deux difficultés traductionnels. Le chapitre 4 présente une réflexion sur les mécanismes intellectuels de l’adaptation publicitaire et sur les différentes lectures que le traducteur doit faire du texte source pour produire un message efficace, respectivement la lecture analytique (rationnelle et raisonnée), puis la lecture empathique, où il anticipe la réaction émotive des cibles. Le cinquième chapitre se concentre sur un aspect de la traduction audiovisuelle presque exclusive à l’industrie publicitaire : la double version, où le traducteur traduit non pas des dialogues apposés à l’image originale, mais plutôt le scénario dans son entièreté, afin de produire un nouveau message vidéo avec des acteurs appartenant à la culture cible. Enfin, notre sixième chapitre est une étude de cas menée en agence de publicité, qui analyse la pratique professionnelle de traducteurs dans leur environnement de travail, les mandats qui leur sont confiés ainsi que les ressources dont ils disposent. Ensemble, ces six chapitres visent à mieux faire connaître la démarche intellectuelle de l’adaptation publicitaire, à comprendre comment différents facteurs influencent le rôle du traducteur au sein d’une agence, à déterminer comment mieux préparer les professionnels de demain à exceller dans le marché très prometteur du marketing international, et à contribuer à l’avancement de la réflexion traductologique par l’étude d’un type de traduction spécialisée qui se démarque par ses pratiques et ses défis aussi intéressants qu’uniques.

Repenser l’histoire de la jouabilité : l’émergence du jeu de stratégie en temps réel

L’objectif de cette thèse est de réfléchir aux enjeux d’une histoire du jeu de stratégie en temps réel (STR). Il s’agit de mieux comprendre les contextes dans lesquels le genre prend sens pour historiciser son émergence et sa période classique. Cette thèse cherche à documenter, d’une part, la cristallisation du STR en tant qu’objet ayant une forme relativement stable et en tant que corpus précis et identifié et, d’autre part, l’émergence des formes de jouabilité classiques des STR. La première partie est consacrée à décrire l’objet de cette recherche, pour mieux comprendre la complexité du terme « stratégie » et de la catégorisation « jeu de stratégie ». La seconde partie met en place la réflexion épistémologique en montrant comment on peut tenir compte de la jouabilité dans un travail historien. Elle définit le concept de paradigme de jouabilité en tant que formation discursive pour regrouper différents énoncés actionnels en une unité logique qui n’est pas nécessairement l’équivalent du genre. La troisième partie cartographie l’émergence du genre entre les wargames des années 1970 et les jeux en multijoueur de la décennie suivante. Deux paradigmes de jouabilité se distinguent pour former le STR classique : le paradigme de décryptage et le paradigme de prévision. La quatrième partie explique et contextualise le STR classique en montrant qu’il comporte ces deux paradigmes de jouabilité dans deux modes de jeu qui offrent des expériences fondamentalement différentes l’une de l’autre.

Virtual reality exposure therapy: 150-degree screen to desktop PC

Virtual reality exposure therapy (VRET) developed using immersive or semi-immersive virtual environments present a usability problem for practitioners. To meet practitioner requirements for lower cost and portability VRET programs must often be ported onto desktop environments such as the personal computer (PC). However, success of VRET has been shown to be linked to presence, and the environment's ability to evoke the same reactions and emotions as a real experience. It is generally accepted that high-end virtual environments ( VEs) are more immersive than desktop PCs, but level of immersion does not always predict level of presence. This paper reports on the impact on presence of porting a therapeutic VR application for Schizophrenia from the initial research environment of a semi-immersive curved screen to PC. Presence in these two environments is measured both introspectively and across a number of causal factors thought to underlie the experience of presence. Results show that the VR exposure program successfully made users feel they were present in both platforms. While the desktop PC achieved higher scores on presence across causal factors participants reported they felt more present in the curved screen environment. While comparison of the two groups was statistically significant for the PQ but not for the IPQ, subjective reports of experiences in the environments should be considered in future research as the success of VRET relies heavily on the emotional response of patients to the therapeutic program.

RESILIÊNCIA EM GESTÃO DE PESSOAS: UM ESTUDO A PARTIR DA APLICAÇÃO DO QUESTIONÁRIO DO ÍNDICE DE RESILIÊNCIA: ADULTOS EM GESTORES DE UMA ORGANIZAÇÃO DE GRANDE PORTE

O contexto atual das organizações é permeado por pressões, crises e incertezas, características da era da globalização, que requer capacidade humana para adaptações. O enfrentamento constante às situações instáveis necessita, em qualquer nível relacional, do que se tem nomeado resiliência. Atualmente, o uso deste termo vem se expandindo devido à sua aplicabilidade no estudo da capacidade humana de resistir à situação de intensa pressão. O termo resiliência foi desenvol vido a partir de estudos de população em estado de risco e vulnerabilidade, e atualmente tem pautado algumas discussões no campo organizacional. Com base neste conceito, objetiva -se, neste trabalho, estudar a resiliência em gestores de pessoas, em uma organização de grande porte com fins lucrativos, da área de Serviços em São Paulo, a partir da aplicação do Questionário do Índice de Resiliência: Adultos - Reivich-Shatté/Barbosa (2006). A metodologia de pesquisa adotada é de cunho exploratório e descritivo. O instrumento utilizado propiciou mensurar os sete fatores constitutivos da resiliência no comportamento humano, sendo eles: administração das emoções, controle de impulsos, otimismo com a vida, aná lise do ambiente, empatia, auto-eficácia e alcançar as pessoas. Os resultados obtidos demonstram que é possível estudar a resiliência em gestores de pessoas, a partir da utilização do instrumento proposto. Este trabalho permitiu também associar os fatores que constituem a resiliência a algumas competências essenciais necessárias para o gestor de pessoas realizar adequadamente suas atividades, sem negligenciar os aspectos de liderança associados à sua atuação.(AU)

Combining data driven programming with component based software development:with applications in geovisualisation and dynamic data driven application systems

Software development methodologies are becoming increasingly abstract, progressing from low level assembly and implementation languages such as C and Ada, to component based approaches that can be used to assemble applications using technologies such as JavaBeans and the .NET framework. Meanwhile, model driven approaches emphasise the role of higher level models and notations, and embody a process of automatically deriving lower level representations and concrete software implementations. The relationship between data and software is also evolving. Modern data formats are becoming increasingly standardised, open and empowered in order to support a growing need to share data in both academia and industry. Many contemporary data formats, most notably those based on XML, are self-describing, able to specify valid data structure and content, and can also describe data manipulations and transformations. Furthermore, while applications of the past have made extensive use of data, the runtime behaviour of future applications may be driven by data, as demonstrated by the field of dynamic data driven application systems. The combination of empowered data formats and high level software development methodologies forms the basis of modern game development technologies, which drive software capabilities and runtime behaviour using empowered data formats describing game content. While low level libraries provide optimised runtime execution, content data is used to drive a wide variety of interactive and immersive experiences. This thesis describes the Fluid project, which combines component based software development and game development technologies in order to define novel component technologies for the description of data driven component based applications. The thesis makes explicit contributions to the fields of component based software development and visualisation of spatiotemporal scenes, and also describes potential implications for game development technologies. The thesis also proposes a number of developments in dynamic data driven application systems in order to further empower the role of data in this field.

Serious games for energy social science research

This paper proposes a set of criteria for evaluation of serious games (SGs) which are intended as effective methods of engaging energy users and lowering consumption. We discuss opportunities for using SGs in energy research which go beyond existing feedback mechanisms, including use of immersive virtual worlds for learning and testing behaviours, and sparking conversations within households. From a review of existing SG evaluation criteria, we define a tailored set of criteria for energy SG development and evaluation. The criteria emphasise the need for the game to increase energy literacy through applicability to real-life energy use/management; clear, actionable goals and feedback; ways of comparing usage socially and personal relevance. Three existing energy games are evaluated according to this framework. The paper concludes by outlining directions for future development of SGs as an effective tool in social science research, including games which inspire reflection on trade-offs and usage at different scales.

Facilitating intuitive-guided learning in a serious game through integration with a learning content management system

Increased global uptake of entertainment gaming has the potential to lead to high expectations of engagement and interactivity from users of technology-enhanced learning environments. Blended approaches to implementing game-based learning as part of distance or technology-enhanced education have led to demonstrations of the benefits they might bring, allowing learners to interact with immersive technologies as part of a broader, structured learning experience. In this article, we explore how the integration of a serious game can be extended to a learning content management system (LCMS) to support a blended and holistic approach, described as an 'intuitive-guided' method. Through a case study within the EU-Funded Adaptive Learning via Intuitive/Interactive, Collaborative and Emotional Systems (ALICE) project, a technical integration of a gaming engine with a proprietary LCMS is demonstrated, building upon earlier work and demonstrating how this approach might be realized. In particular, how this method can support an intuitive-guided approach to learning is considered, whereby the learner is given the potential to explore a non-linear environment whilst scaffolding and blending provide guidance ensuring targeted learning objectives are met. Through an evaluation of the developed prototype with 32 students aged 14-16 across two Italian schools, a varied response from learners is observed, coupled with a positive reception from tutors. The study demonstrates that challenges remain in providing high-fidelity content in a classroom environment, particularly as an increasing gap in technology availability between leisure and school times emerges.

Becoming Other: Virtual Realities in Contemporary Science Fiction

The purpose of this thesis was to explore the boundary between human and other created by virtual worlds in contemporary science fiction novels. After a close reading of the three novels: Surface Detail, Existence, and Lady of Mazes, and the application of contemporary literary theories, the boundary presented itself and led to the discovery of where the human becomes other. The human becomes other when it becomes lost to the virtual world and no longer exists or interacts with material reality. Each of the primary texts exhibits both virtual reality and humanity in different ways, and each is explored to find where humanity falls apart. Overall, when these theories are applied to real life there is no real way to avoid the potential for fully immersive virtual worlds, but there are ways to avoid their alienating effects.
