En représentant la promesse de répliquer certaines fonctions écosystémiques et de permettre la vie dans l’invivable, certaines technologies spatiales nourrissent un imaginaire de la catastrophe qui laisse penser que tout puisse continuer comme avant. Au travers d’une enquête sur des systèmes de support de vie biorégénératifs développés dans le contexte des programmes spatiaux habités, cet essai examine un mode d’existence capsulaire qui nie les planétarités concrètes en proposant d’habiter des sphères à l’atmosphère contrôlée. Il étudie aussi quelques trajectoires singulières qui (...) font imploser le paradigme capsulaire en prêtant attention aux alliances et affects partagés entre les vivants. (shrink)

Human beings adapt the spontaneous pace of their actions to interact with the environment. Yet, the nature of the mechanism enabling such adaptive behavior remains poorly understood. The aim of the present contribution was to examine the role of attention in motor timing using time series analysis, and a dual task paradigm. In a series of two studies, a finger-tapping task was used in sensorimotor synchronization with various tempi and motor complexity. Time series analyzes indicated that two different timing strategies (...) were used depending on the speed constraints. At slow tempi, tapping sequences were characterized by strong negative autocorrelations, suggesting the implication of cognitive predictive timing. When moving at fast and close-to-spontaneous tempi, tapping sequences were characterized by less negative autocorrelations, suggesting that timing properties emerged from body movement dynamics. The analysis of the dual-task reaction times confirmed that both the temporal and spatial constraints impacted the attentional resources allocated to the finger-tapping tasks. Overall, our work suggests that moving fast and slow involve distinct timing strategies that are characterized by contrasting attentional demands. (shrink)

In this discussion piece, eight scholars in geography, urban planning, and agri-food studies from the United States (US) and France engage in a bi-national comparison to deepen our collective understanding of food and land justice. We specifically contextualize land justice as a critical component of food justice in both the US and France in three key areas: access to land for cultivation, urban agriculture, and non-agricultural forms of food provisioning. The US and France are interesting cases to compare, considering the (...) differences and similarities in their colonial and agricultural histories, persistent and systemic race and class-based inequities in land access, and the roles of public bodies and social movements. In this paper, we synthesize literature, share reflections, and offer directions for future scholarship, including a broader comparative research agenda. An important difference we found is in the degree of scholarly attention to race and how it mediates access to land. We also observe that few scholars articulate a clear definition of justice in their work, nor do they share a common justice framework. We hope that this paper contributes to a more robust food and land justice framework for the use of scholars, practitioners and activists. (shrink)

Ce livre est la version remaniée d'une thèse dont l'Auteure est désormais maître de conférence à l'EPHE et travaille également à l'Institut Européen en Sciences des Religions récemment fondé sur la recommandation de Régis Debray. Isabelle Saint-Martin évoque un monde en voie de disparition, celui des images pieuses qui ont contribué à la formation religieuse des chrétiens de la génération de nos grands et arrière-grands-parents.

Dans la « campagne participative » nationale de Ségolène Royal et de son association « Désirs d'avenir », le formatage des activités par les interfaces numérisées joue un rôle crucial dans l'appropriation de pratiques politiques innovantes, ainsi que dans le régime d'implication des militants. L'épaisseur sémiotique de la campagne influence la dynamique organisationnelle. Elle contribue à légitimer les positions de la candidate; elle facilite également la rectification de ses propos. Ces pratiques reposent sur des micro-dispositifs logiciels très rustiques, souvent (...) des offres grand-public gratuites.In the "participatory campaign" National Ségolène Royal and its association 'desires for the future ", the formatting of activities by Digital interfaces plays a crucial role in the appropriation of innovative policy practices, as well as involvement in the scheme activists.

In the French presidential election, both candidates tried to keep their domestic life separate from their campaign. Ségolène Royal is not married to François Hollande, the father of her four children. When asked whether they were a couple, Royal replied, “Our lives belong to us.” Similarly, in response to rumors that President-elect Nicholas Sarkozy’s wife had left him, a spokesman for Sarkozy said, “That’s a private matter.” The French have a long tradition of respecting the privacy of their politicians’ (...) personal lives, and French public opinion is more broad-minded than in the United States, where an unwed mother of four would have no chance of being nominated for the presidency by a major party. Indeed, last month, Randall Tobias, the top foreign aid adviser in the US State Department, resigned after acknowledging that he had used an escort service described as providing “high-end erotic fantasy” – although Tobias said he only had a massage.

The article presents an analysis of the ways in which knowledge is displayed, contested and renegotiated in the 2007 French presidential debate between Ségolène Royal and Nicolas Sarkozy. Knowledge displays can be achieved through a series of ‘neutral’ resources, such as informing, explanation or comment, or through face-damaging resources, such as questioning an unknowledgeable interlocutor to prove his inferior epistemic status and boost one’s own. The article focuses on this latter type of knowledge display where a knowledgeable participant engages (...) in question–answer sequences with an unknowledgeable respondent in front of a third party. The article also undertakes an analysis of the multimodal strategies employed by the participant to discredit the opponent. The article intends to contribute to the existent literature on epistemic stance by offering a prototypical example of incongruence between the epistemic status of the questioner and the epistemic stance he adopts.
