    Psychopathologie de l’habit quotidien

    No full text
    International audienceThere are relatively few psychological studies on this practice. Other disciplines can help us identify how the psyche is involved. Browsing through scientific and human literature allows us to glimpse the limits of each model and to open up to other considerations.Clothing is caught in the traditional articulation between nature and culture, in the question of its meaning as well as its enjoyment, in the perspective of confinement or liberation of bodies. And it participates in the eminent issue for the subjectivity of what is shown and hidden.This therefore invites us to outline what suffering this can cause, but also what people manage to do with it to bear their difficulties and maintain a little bit of holding.Il y a relativement peu d’études de psychologie sur la pratique de l’habillage. Les autres disciplines peuvent nous aider à repérer comment le psychisme est impliqué. Parcourir la littérature scientifique et humaine permet d’entrevoir les limites de chaque modèle et d’ouvrir à d’autres considérations.Le vêtement est pris dans l’articulation traditionnelle entre nature et culture, dans la question de son sens comme de sa jouissance, dans la perspective d’enfermement ou de libération des corps. Et il participe à l’enjeu éminent pour la subjectivité de ce qui se montre et se cache.Dès lors, cela nous invite à esquisser de quelles souffrances il peut être la matière mais aussi à estimer ce que les uns et les autres réussissent à en faire de manière à porter leurs difficultés et avoir un peu de tenue

    Participatory and multi-disciplinary science dataset and surveys for the assessment of the microbiological and behavioural factors influencing fresh fruits and vegetables' waste at home

    International audienceFresh fruits and vegetables (FFV) represent the largest part of food waste at the consumer level. This waste directly results from FFV physiological and microbiological spoilage, itself intricately linked to behavioural factors such as consumer practices, including purchase, storage and hygiene practices, but also consumers’ perceptions towards spoilage. Based on a dual approach combining microbiological and behavioural sciences, we examined the link between FFV waste produced by 49 volunteering French households, measured using connected bins, the microbial ecology of their storage compartments, using culture-dependent and -independent approaches, and their consumer behaviour, cleaning and storage practices, through in-depth interviews and a dedicated survey. An exploratory qualitative survey carried out on 17 individuals followed by two quantitative data collections on 1048 and 815 representative French consumers enabled us to identify anti-FFV waste practices and to cluster consumers according to their anti-FFV waste behaviours. Spoilage dynamics of commonly consumed FFV, according to storage temperature, microbial contamination level and the presence or absence of surface wounds, were also performed in controlled conditions. This citizen-science-based dataset covers a wide array of microbiological and behavioural factors related to domestic FFV waste, as well as real measurements of waste volumes thanks to the innovative use of connected bins. Altogether, this data could provide interesting insights into more effective and accessible guidelines for FFV waste reduction at the consumer level, and thus to a potential reduction of global food waste and its related costs

    Biopouvoir en culture de l’écran

    No full text
    International audienceLa notion de biopouvoir défi nie par Foucault comme le contrôle de la vie par une forme de pouvoir souvent (mais pas seulement) incarnée par l’État, a fait preuve de sa pertinence lors de la pandémie de COVID-19. Cet ouvrage analyse plus particulièrement les formes multiples du biopouvoir, les résistances et les adhésions qu’il peut susciter. Il tente de comprendre leur mise en œuvre dans la culture de l’écran telle que vécue par nos sociétés contemporaines. Littératures anglophones et productions télévisuelles, de Margaret Atwood à Don DeLillo, de Desperate Housewives à Westworld, côtoient ainsi des analyses des systèmes de gestion d’épidémie, de reconnaissance faciale, et des figures tutélaires de la fiction comme le monstre ou le zombie. Le livre permet de réfléchir aux formes du biopouvoir, dans ses manifestations corporelles, sociales, numériques, et culturelles, à la fois sous l’angle de la discipline et de la biopolitique

    Revue sur les stockage d'énergie thermique horizontal enterré à faible profondeur (HUTES)

    No full text
    International audienceUnderground thermal energy storage (UTES) are widely recognised as one of the most promising technologies for building applications due to their high energy efficiency and low operating costs. In recent years, horizontal underground thermal energy storage (HUTES) have gained recognition as effective solutions for storing intermittent renewable energy. In these systems, heat exchangers play a crucial role as heat-conducting media, with a predominantly horizontal distribution. Many notable studies have been conducted in recent years. However, most existing reviews have focused on vertical UTES, addressing their design, performance and applications, as well as horizontal ground heat exchangers integrated into geothermal heat pump systems, named as Horizontal Ground source Heat Pump. A systematic synthesis analysing the thermodynamic performance of HUTES, enabling the use of energy from renewable resources, is therefore essential. This review aims to summarise the experimental benches and analytical and numerical models of shallow HUTES with linear, spring and spiral loops, as well as their advantages and disadvantages. Evaluations and comparisons between different configurations of HUTES are presented. Particular attention is paid to the various internal and external factors influencing the thermal properties of HUTES: geometric parameters, thermophysical properties of different materials, operating and climatic conditions. Finally, conclusions are drawn on the choices to be made in order to develop the most efficient HUTES. Finally, this review offers suggestions for future developments and recommendations for research directions related to HUTES, providing avenues for further research.Le stockage souterrain d'énergie thermique (UTES) est largement reconnu comme l'une des technologies les plus prometteuses pour les applications dans le bâtiment en raison de son rendement énergétique élevé et de ses faibles coûts d'exploitation. Ces dernières années, le stockage souterrain horizontal d'énergie thermique (HUTES) s'est imposé comme une solution efficace pour stocker l'énergie renouvelable intermittente. Dans ces systèmes, les échangeurs de chaleur jouent un rôle crucial en tant que moyens de conduction thermique, avec une distribution principalement horizontale. De nombreuses études notables ont été menées ces dernières années. Cependant, la plupart des analyses existantes se sont concentrées sur les UTES verticaux, abordant leur conception, leurs performances et leurs applications, ainsi que sur les échangeurs de chaleur horizontaux intégrés dans les systèmes de pompes à chaleur géothermiques, appelés « pompes à chaleur géothermiques horizontales ». Une synthèse systématique analysant les performances thermodynamiques des HUTES, permettant l'utilisation d'énergie provenant de ressources renouvelables, est donc essentielle. Cette revue vise à résumer les bancs d'essai expérimentaux et les modèles analytiques et numériques des HUTES peu profonds avec des boucles linéaires, à ressort et en spirale, ainsi que leurs avantages et leurs inconvénients. Des évaluations et des comparaisons entre différentes configurations de HUTES sont présentées. Une attention particulière est accordée aux différents facteurs internes et externes qui influencent les propriétés thermiques des HUTES : paramètres géométriques, propriétés thermophysiques des différents matériaux, conditions d'exploitation et climatiques. Enfin, des conclusions sont tirées sur les choix à faire afin de développer les HUTES les plus efficaces. Enfin, cette étude propose des suggestions pour les développements futurs et des recommandations pour les orientations de recherche liées aux HUTES, ouvrant ainsi la voie à de nouvelles recherches

    Practical management of rheumatic immune-related adverse events occurring with immune checkpoint inhibitors: A narrative review

    No full text
    International audienceImmune checkpoint inhibitors (ICIs) have dramatically changed the management of cancer and their indications are expanding, leading to an increase in immune-related adverse events (irAEs). Recently, attention has focused on previously underestimated rheumatic irAEs, including inflammatory arthritis (IA), polymyalgia rheumatica-like phenotypes and Sicca syndrome, but also fasciitis, and rare but severe immune mediated myositis, with a possible association with myasthenia-like symptoms or myocarditis. Rheumatic irAEs may have a prolonged course and affect a patient's quality of life. Patients with IA or systemic autoimmune disease prior to ICI initiation are also at risk of flares. Current management of rheumatic toxicities relies on the opinion of experts, mostly based on the management of the classical rheumatic conditions they mimic. Due to the lack of high-quality data in the literature, few recommendations are available, with remaining concerns regarding the impact of immunosuppressive drugs on cancer response. The aim of this article is to provide practical guidelines to help rheumatologists and oncologists in their daily practice to deal with ICI related inflammatory rheumatic conditions, from the introduction of an ICI in the case of preexisting autoimmune disease, to the occurrence of rheumatic toxicity, as well as discussions concerning ICI rechallenge after a severe rheumatic irAE
