Focusing on European countries, this article investigates the link between market-oriented institutions, as measured by the Economic Freedom Index, and the production of energy from renewable sources. A dynamic panel approach shows that this correlation is positive and significant while the subcomponents of the Economic Freedom Index reveal that not all market-oriented institutions have a similar impact. Indeed, long-term price stability and freedom to trade boost the reliance on renewable energies whereas the importance given to markets rather than governments has no significant impact. [less ▲]

To look at energy consumption through a different lens, we have developed the conceptual framework of habitual practices. The objective of the present paper is to propose an empirical application of this framework, with the aim of unravelling the constitutive ‘ingredients’ of energy-consuming practices. Therefore, we investigate whether discussing the relationship of people with their homes could help circumventing the methodological difficulties that inevitably arise when trying to approach less tangible (albeit crucial) elements such as norms and attached meanings. The empirical material comes from group conversations where participants discussed the extent to which a home has to be practical, comfortable and convivial in connection with a series of elements. The results confirm that this methodological setting generated useful insights for a finer understanding of energy-consuming practices and their underlying drivers. A related crucial finding is the role of key appliances – those with more contrasted use and attached meanings – which appear to mediate the interplay between comfort, conviviality, and practicality. A promising avenue for future research would thus be to further investigate the role of those key appliances as potential markers of wider tendencies in energy consumption and useful for designing segmentation strategies.

Lorsque Spacewar!, considéré comme un des premiers jeux vidéo, voit le jour en 1962 dans les salles du Massachussets Institute of Technology, il marque le début d’une longue relation entre ce médium et la science-fiction. À l’heure où l’informatique est encore fort peu micro, la thématique spatiale que ce précurseur exploite présente en effet un avantage certain : celui de déployer à l’écran un « espace dont la principale caractéristique est le vide [...] un lieu qui exige moins de puissance de calcul » (Triclot, 2011). De l’émergence de cette culture hacker dans les années 1960 à la production actuelle, le jeu vidéo a constamment puisé dans les ressorts propres à la science-fiction – que ce soit les accents cyberpunk d’un Deus Ex : Human Revolution (Square Enix, 2011), l’uchronie d’un Wolfenstein : The New Order (Bethesda Softworks, 2014) ou encore la dystopie constitutive d’un Bioshock (2K Games, 2007). Cette richesse spécifique a pourtant été peu interrogée. [less ▲]

Cette thèse analyse l’impact d’une prise en charge posturale associée à l’utilisation d’un coussin triangulaire dynamique sur la position assise, les capacités cognitives, la concentration et le bien-être de l’enfant en début d'école primaire. Elle comporte 4 sections principales. La revue de la littérature présentée dans la première section souligne le rôle de l’école et plus spécifiquement l’impact du mobilier scolaire sur la santé et les apprentissages des élèves. La deuxième section consiste à mettre en place et à étudier les qualités métrologiques d’une batterie de tests permettant d’évaluer la qualité de la position assise, les capacités posturales, le comportement en classe et les capacités cognitives d’enfants du premier cycle du primaire. La troisième section comprend trois études de terrain évaluant l’influence de la prise en charge en milieu scolaire. La partie principale consiste en un suivi longitudinal réalisé au cours des deux premières années primaires. Dans ce cadre, le cousin dynamique a amélioré la qualité de la position assise, les plaintes musculo-squelettiques, les capacités cognitives et le comportement des enfants en classe. Une première étude complémentaire a mis en évidence le caractère instantané de l’effet de la prise en charge et une seconde a confirmé l’impact positif du coussin dans une population présentant des troubles de l’attention. Enfin, la quatrième section comporte deux études réalisées au sein du Laboratoire d’Analyse du Mouvement Humain : une analyse biomécanique de la position assise a précisé l’effet positif et immédiat du coussin dynamique et une évaluation du contrôle moteur lombaire a démontré une meilleure proprioception lombaire chez les enfants habitués à utiliser le coussin. En conclusion, bien que cette recherche ne porte que sur une partie des facteurs entrant en ligne de compte pour le bien-être des élèves en classe ainsi que pour leur réussite scolaire, les différentes analyses et perspectives développées tout au long de cette thèse suggèrent la pertinence d’un coussin dynamique dans la mise en place de campagnes posturales préventives.

Conjugated polymers have been widely studied as flexible, versatile semiconductors in organic electronics. However, the material stability is one of the problems limiting their applications. Thus, understanding the degradation process of conjugated polymers is crucial. In this work, we monitored the chain scission of the model polymer MEH-PPV in solutions under different conditions by assessing its molecular weight using Gel permeation chromatography and optical spectral measurements. We showed that changes in the UV-VIS spectrum can be seen only when the degradation has already progressed substantially. Fluorescence spectrum was found to be almost totally insensitive to the degradation stage of the polymers. We demonstrate that chain scission in solutions happens even in the dark leading to a decrease of about 15% of the molecular weight after just one day of storage. If exposed to room-light, the chain length decreases about 10 times over one day of exposure. Using stronger light intensity or enriching the solution with oxygen accelerates the degradation process dramatically. The rate of the reaction follows approximately a square root dependence with light intensity and oxygen concentration. We conclude that some extent of polymer degradation is difficult to avoid in common laboratory practices since to prevent it one needs to work in oxygen free atmosphere in the dark. Preparation of polymer films from partially degraded solutions might lead not only to losing the connection between the molecular weight and the opto-electronic properties but also to unintentional doping of the semiconductor by products of chains scission reactions.

Immersion is an omnipresent concept in the field of video games: it appears in the players’ debates, in the discourses of the industry, in the press and in the academic research. For developers and journalists, immersion is a recurrent promise repeated at every technological turn: the promise that, one day, technology will allow us to literally enter the fictional worlds. In the academic field, the term is also at the centre of many works: researchers in game studies frequently use the concept of immersion to describe the playing activity as a “diving” into a video game universe. However, this notion gives rise to several epistemological issues. First, the word immersion continues to convey negative preconceptions against play and fiction, keeping alive the idea that they are alienating practices. Secondly, in the video games domain, the concept is extremely vague and shape-shifting. Besides, researchers rarely question the desirability of the immersion state: it is most often postulated as the purpose and as the enviable horizon of any gaming practice. As a consequence, the concepts of immersion, fun, pleasure and even of play end up getting confused and superimposed into the theories. This paper will defend the idea that it is necessary to escape from the theoretical paradigm of “immersion”: on the one hand, because it presents some incompatibility with the theories of play, and, on the other hand, because it prevents us from describing the many other forms of relationship that players can have with games.

Connectivity has become an increasingly used concept in hydrological and sediment research. In order to quantify it, various indices have been proposed since the start of the 21st century including the index of connectivity developed by Borselli et al. (2008). This index is based on a limited number of factors, the most important one being topography. Sediment connectivity indices values are likely to depend on the digital elevation model (DEM) resolution. The aim of this study was, first, to compare the effect of DEM pixel size (between 0.25 and 10 m, using an UAV) in the Belgian loess belt, a lowland area. We show that the index values were lower when the pixel size decreased (a difference of about 20 % in value between 0.25 and 10 m). In addition, the impact of linear features in the watershed (e.g., grass strip, bank and road) was lower with the largest pixel sizes, and the connectivity pattern was affected with a pixel size of 5 m or more. At lower pixel sizes (1 m or below), some more disconnected regions appeared. These corresponded to zones where there had been water stagnation during and after rainfalls, and was corroborated by field observations. This confirmed the need for a proper resolution according to the objectives of the study. The second aim of this study was to deduce a minimum pixel size for connectivity study, helping local erosion or sedimentation location and consequent land management decisions. In our context, 1 m stands as the optimum DEM resolution. This pixel size permitted to locate all “key areas” in terms of erosion. Very high resolutions (<0.5 m) did not generate much more information, and their calculation time was far greater. [less ▲]
