This work presents an hydrodynamical model of heat stroke, which is a physiopathological state of stress, due to an exposure of animals to an ambient temperature of approximatively 40°C during two hours. The evolution of body temperature during this stress process is characterised by three phases. A first phase of increase is followed by a plateau which occurs before a second phase of increase which can be lethal. The model is based on the analogy of a boat progressively caught in (...) a whirlpool. The evolution of the degree of freedom lost by the boat is mathematically analysed and this study leads to the same three phases. The theoretical curves calculated during this study are well in agreement with the experimental curves obtained with animals. This analogy is compared to a previous one which has been made during another experiment with animals constrained by chemical intoxications. It seems that stress can be considered as a vital vorticity and that hydrodynamic models are powerful tools in understanding this physiopathological state. (shrink)

Cet article retrace une étape essentielle dans l'histoire de la télévision européenne de service public : la transformation des représentations de son public - d'un public avide de savoir, à la fois de droite et de gauche, elle est passée à un public populaire qui vient en nombre chercher le loisir immédiat, une nouvelle forme de la «populace» d'Ancien Régime. Ce changement a précédé la mesure d'audience qui l'incarne et le confirme aujourd'hui. Le passage d'un public à l'autre pose un (...) défi à la pensée de la culture populaire, emprisonnée l'élitisme traditionnel, le néo-élitisme «de gauche» qui s'avance masqué , un néo-populisme qui donne le primat au texte et un déni du public populaire traité comme une fiction . Contre une pensée globale du populaire qui traite ensemble « le » public populaire et « la » télévision, il faut dépasser les hiérarchies culturelles implicitement ou explicitement à l'oeuvre dans les paradigmes dominants.This article recalls a major episode in the history of European public service television: the transformation of the representations of the public - from a "popular" audience, eager to be educated which came both from the right and the left, which still had a revolutionary people in view, the public became a popular audience eagerly seeking disreputable leisure in throngs: a return of the Ancient Regime's rabble. This episode constitues a challenge for theories of popular culture, all too often imprisonned traditional elitism, neo-elitism which claims than a non manipulated popular audience would have a "better taste", a neo-elitism, a neo-populism which rehabilitates the popular audience by dissolving it into the texts , and finally a denial of popular audiences treated as a "fiction" . Against a global view of television and its audience, it is necessary to go beyond the cultural hierarchies implicitly or explicitly at work in the dominant paradigms. (shrink)

Cet article s'attache à analyser la violente controverse qui s'est développée, sur plusieurs années, autour de la diffusion d'images de la mort d'un enfant palestinien par la deuxième chaîne française en septembre 2000. Originale de par ses publics et les vecteurs de mobilisation , cette controverse révèle une forme de débat public complexe, où l'identité sociale et professionnelle des acteurs en cause est redessinée par la circulation des représentations et des arguments.This article seeks to analyze violent controversy that has developed (...) over many years around the dissemination of images of the death of a Palestinian child by the second French channel in September 2000. Original by its audiences and vector mobilization , this controversy reveals a complex form of public debate, where social and professional identity of the actors involved is redesigned by the circulation of representations and arguments.

Breastfeeding advocates and global health agencies have been sounding alarms about the dangers of digital marketing practices of the formula-feeding industry. This study comprised a feminist discourse analysis of materials produced (blog, social media posts, comments) in a paid partnership between baby formula brand Enfamil and an influencer, Marilou Bourdon from Trois fois par jour. Our analysis reveals a sophisticated marketing campaign that co-opts feminist critiques of breastfeeding promotion discourse while carefully avoiding explicitly violating the International Code of Marketing (...) of Breast-milk Substitutes. Underlying this campaign is a rhetoric reliant on pathos to assuage maternal guilt and shame for feeding formula. (shrink)

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.
