Transitions to sustainable consumption and production patterns now appear as a widely acknowledged necessity for contemporary food systems. Sustainable transition processes raise major issues of social justice as they often exclude some actors and social groups\, as the literature on alternative food networks has amply shown. Based on three case studies anchored in different national contexts (France\, Brazil and Belgium)\, which all emerged at the interface of civil society and public policy\, the aim of this article is to show how their promoters try to tackle together sustainable transitions\, food justice and food democracy\, and thus make food system transitions not only sustainable but also socially just. They adopt on the one hand\, an analytical stance on transitions to more sustainable food practices\, on inequalities of access and on participation\, and on the other hand\, an experimental stance leading them to put to test specific mechanisms to support these transitions\, to alleviate food injustice and to favour participation and thus also food democracy. We show that it is by combining these analytical and experimental stances that these social experiments succeed to different degrees in articulating sustainable transitions\, food justice and food democracy.

In times of social and moral crises\, sport has often been called to boost individual moral development. By the same token\, outdoor activities are viewed as good educational practices to enhance environmental responsibility. However\, the present paper argues that these physical activities are currently following the same technological development trend as the mainstream society\, and challenges this trend itself from the viewpoint of the work of Hans Jonas (1984) by critically asking this question: do outdoor activities really enhance environmental responsibility? The research supporting this paper is based on a qualitative inquiry using interviews with outdoor activities practitioners: mountain guides and white water sports instructors. The findings of this research show that environmental responsibility development depends on the sport contexts. It is fostered in slow and none-technological activities (e.g.\, trekking) and lowered in fast and technological activities (e.g.\, canoeing\, kayaking). The paper concludes with the following paradox reached by the preliminary research results: the birth of modern technology calls for greater need of environmental responsibility (Jonas\, 1984)\, but it may also prevent its development at the same time.

Many conspiracy theories appeared along with the COVID-19 pandemic. Since it is documented that conspiracy theories negatively affect vaccination intentions\, these beliefs might become a crucial matter in the near future. We conducted two cross-sectional studies examining the relationship between COVID-19 conspiracy beliefs\, vaccine attitudes\, and the intention to be vaccinated against COVID-19 when a vaccine becomes available. We also examined how these beliefs predicted support for a controversial medical treatment\, namely\, chloroquine. In an exploratory study 1 (N = 409)\, two subdimensions of COVID-19 conspiracy beliefs were associated with negative attitudes toward vaccine science. These results were partly replicated and extended in a pre-registered study 2 (N = 396). Moreover\, we found that COVID-19 conspiracy beliefs (among which\, conspiracy beliefs about chloroquine)\, as well as a conspiracy mentality (i.e.\, predisposition to believe in conspiracy theories) negatively predicted participants’ intentions to be vaccinated against COVID-19 in the future. Lastly\, conspiracy beliefs predicted support for chloroquine as a treatment for COVID-19. Interestingly\, none of the conspiracy beliefs referred to the dangers of the vaccines. Implications for the pandemic and potential responses are discussed.

Remembering one's past transgressions of a social norm is known as an effective paradigm for enhancing pro-social and ecological behaviours. Our study aimed to show that reminding norm transgressions can arise cognitive dissonance and can lead to behavioural change as induced hypocrisy does. In particular\, we tested whether inconsistency between the self-concept and the remembered past transgressions is or is not likely to encourage behavioural change. To reach this goal\, we conducted an experiment comparing induced hypocrisy\, injunctive inconsistency and descriptive inconsistency with five comparison conditions. The results showed that\, as observed with the induced hypocrisy paradigm\, presenting a salient injunctive norm and its past transgressions enhances psychological discomfort\, actual donation and donation amounts for an ecological association. The discussion addresses applied perspectives and theoretical implications.

Background Bariatric surgery offers an opportunity for physical activity (PA) promotion due to patients’ increased ability to engage in PA. Technology-based PA interventions are promising tools for promoting PA to support patients in this key period. The Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model is a recognized theoretical model for examining technology acceptability. Although a previous study reported that 92% of women with obesity have high acceptability of at least one technology-based PA intervention\, little is known about the factors that lead to different levels of acceptability between technologies and therefore the reasons for choosing a preferred intervention. Objective The purpose of this study was to (1) characterize the acceptability of 3 technology-based PA interventions (ie\, telehealth\, active video game\, mobile app) in the context of bariatric surgery\, and (2) explore patients’ preference motives. This study\, using a qualitative design\, examined the suitability of the UTAUT2 model in this specific context. Methods Participants (n=26) read written French descriptions of the technology-based PA interventions with illustrations and chose their preferred intervention. Semidirective interviews were conducted to explore the reasons for their choice of the preferred intervention\, notably using the UTAUT2 framework. Data were analyzed based on inductive and deductive approaches. Results All participants who preferred a technology-based PA intervention (ie\, active video game\, n=10; mobile app\, n=10; telehealth\, n=6) expressed a behavioral intention to use it. In addition\, some of them expressed a high behavioral intention to use another technology (ie\, active video game\, n=4; mobile app\, n=1; telehealth\, n=7). All the constructs of the UTAUT2 emerged during the qualitative interviews and were specified through subcategories. Additional constructs also emerged\, especially other motivational factors. Conclusions This study showed that\, in the context of technology-based PA interventions for postbariatric patients\, the UTAUT2 is suitable\, although additional motivational factors (which were not considered by the UTAUT2 model) should be considered.

Introduction Fine lavender and lavandin are perfume and medicinal plants originate from the South of France and are widely cultivated for their essential oils. Recently\, cultivated plants suffered from a severe decline in France\, due to the propagation of the yellow decline disease. This disease is caused by the stolbur phytoplasma\, a bacterium transmitted by a sap-sucking insect\, the planthopper. Objectives In order to understand the complex relationships between host plant\, pest\, pathogen and environment responsible for the yellow decline of lavender\, we use a metabolomic approach to highlight changes in chemical emissions from asymptomatic ("healthy") and symptomatic ("infected") plants. Methods Volatile compounds produced by fine lavender and lavandin were collected in the field using a dynamic head-space extraction approach. Afterwards\, compounds trapped on Tenax adsorbent were thermodesorbed and analysed using an automated thermal desorption-gas chromatography-mass spectrometry (ATD-GC-MS). Multivariate statistical analyses was performed using principal component analysis and partial least square discriminant analyses. Results The untargeted screening of volatiles allowed the separation of asymptomatic and symptomatic plants according to their emissions. The approach was sufficiently accurate so as to separate the emissions according to the different stages of infection. Twelve compounds were found to be deregulated metabolites of yellow disease infection\, common to fine lavender (variety 7713) and lavandin (variety abrial). Conclusion The metabolomic approach allowed for the effective identification of chemical variations between infected and healthy plants in a complex field environment.

Dans son désir d’écrire son propre mythe\, Jean-Luc Lagarce investit l’antique cité romaine\, Carthage. Le souci de réalisme du dramaturge se dissout très vite après le titre\, pour laisser place à une fiction plongée dans l’indétermination. Dès lors\, le dramaturge compose\, à partir d’un mythe antique\, une fiction universelle dans l’air du temps. Entre emprunts classiques et discours décousu\, le drame lagarcien jouit d’une identité propre\, résolument contemporaine mais revendiquant néanmoins un héritage.

La présente étude a pour vocation de mettre à jour la teneur des rapports qui se nouent entre les langues et la musique dans l’œuvre de quatre poétesses de la modernité\, toutes plurilingues\, Marina Tsvetaeva\, Alejandra Pizarnik\, Amelia Rosselli et Michèle Finck. Il s’agit de montrer comment la musique intervient dans un contexte où le plurilinguisme apparaît comme une ressource poétique mais aussi comme un vecteur de troubles dans le rapport des poétesses au langage et au réel. Si le plurilinguisme confine parfois à l’alinguisme\, il est à l’origine d’une parole poétique qui porte l’espoir de se constituer en langue propre\, notamment par le recours aux ressources de la musique. Il s’agit aussi d’explorer dans cet article la présence de la métaphore architecturale\, pour montrer comment les poétesses érigent des édifices poétiques fondés sur le son\, à partir des restes de la tour de Babel.

L'évolution de la politique française d’internationalisation de l’enseignement supérieur\, in situ et à l’international\, est significative de profondes transformations du marché mondial de l'enseignement supérieur. La concurrence entre États s’est exacerbée et a généré de nouveaux standards internationaux de certification et une financiarisation croissante des formations. L’espace mondial de l’enseignement supérieur s’est également considérablement reconfiguré : aux anciens pôles occidentaux de formation se sont ajoutés de nouveaux pôles dans les pays émergents. La volonté politique de gagner des parts de ce marché éducatif a enfin donné jour à l’externalisation d’institutions universitaires occidentales dans des pays du Sud. L’article met en évidence deux conséquences majeures de ces processus : d’une part\, une transformation des périmètres du marché mondial d’enseignement supérieur\, d’autre part une reproduction accrue des élites.
The emergence of money: Computational approaches with fully and boundedly rational agents

Année : 2019

We discuss the emergence of money in a Kiyotaki and Wright (J Polit Econ 97:927–954\, 1989) environment through two computational methodologies. One assumes that agents are fully rational and coordinate on Nash equilibria. The other considers boundedly rational agents whose choices are guided by a classifier system à la Marimon et al. (J Econ Dyn Control 14:329–373\, 1990). We apply the two methodologies to study the conditions under which individuals can learn to play speculative strategies—to accept a high-storage-cost good as money. Our analysis suggests that\, while in both types of systems money can emerge along a dynamic path\, boundedly rational agents make conflicting choices at times\, even when the classifier system provides clear information about the likely gains of a trade.
Debunking the granular origins of aggregate fluctuations: from real business cycles back to Keynes

In this work we study the granular origins of business cycles and their possible underlying drivers. As shown by Gabaix (Econometrica 79:733–772\, 2011)\, the skewed nature of firm size distributions implies that idiosyncratic (and independent) firm-level shocks may account for a significant portion of aggregate volatility. Yet\, we question the original view grounded on “supply granularity”\, as proxied by productivity growth shocks – in line with the Real Business Cycle framework–\, and we provide empirical evidence of a “demand granularity”\, based on investment growth shocks instead. The role of demand in explaining aggregate fluctuations is further corroborated by means of a macroeconomic Agent-Based Model of the “Schumpeter meeting Keynes” family Dosi et al. (J Econ Dyn Control 52:166–189\, 2015). Indeed\, the investigation of the possible microfoundation of RBC has led us to the identification of a sort of microfounded Keynesian multiplier.

Dans le domaine des politiques migratoires\, l’ethnographie des administrations des étrangers s’avère particulièrement pertinent. La recherche\, conduite entre 2010 et 2013\, s’appuie sur l’analyse de la littérature grise et sur un travail d’observation dans plusieurs directions territoriales de l’Office française de l’Immigration et de l’Intégration (OFII) et lors des formations dispensées dans le cadre du contrat d’accueil et d’intégration (CAI). Des entretiens ont également été conduits avec des agents de cet office\, des formateurs et des signataires du CAI. Ce papier propose de revenir sur l’enquête ethnographique conduite à l’OFII et de réfléchir à ce que l’ethnographie nous apprend des politiques migratoires. Nous montrerons d’abord que la confrontation des discours juridiques et institutionnels aux pratiques administratives a permis de mettre en évidence la manière dont le CAI est mis en œuvre par les agents de l’OFII et les formateurs. On s’intéressera en particulier à la prescription des formations et à la manière dont le thème de la laïcité est présenté lors de la formation civique. Puis\, nous verrons que l’ethnographie du CAI permet d’analyser la manière dont le dispositif est appréhendé par les signataires et de mieux comprendre les carrières migratoires des étrangers arrivant en France.

Le Digital Markets Act proposé le 15 décembre 2020 par la Commission européenne vise à fournir des outils complémentaires à ceux dont elle dispose au titre de l’application des règles de concurrence. Il ne s’agit pas ici de poursuivre un objectif d’efficacité (dont le critère du bien-être du consommateur pourrait être une matérialisation) mais de garantir la contestabilité des marchés et l’équité et la loyauté de la concurrence sur ces derniers. Cette contribution montre pour quelles raisons la concurrence pour le marché peut être plus difficile à garantir sur les marchés dans lesquels sont actives les grandes firmes du numérique et pour quelles raisons la concurrence dans le marché peut être biaisée par leur puissance économique.

Les élections régionales de 2021 en région Sud-PACA ont au final livré un résultat assez proche des grandes tendances observées au niveau national : en dépit de sondages prometteurs\, le RN a échoué une nouvelle fois à s’emparer d’une région qui lui semblait promise. Cet échec en PACA\, auquel ont fait écho les déconvenues du RN dans plusieurs grandes autres régions que l’on pensait à sa portée\, montre les limites de la stratégie de normalisation du parti voulue par Marine Le Pen et prive cette dernière du grand marchepied électoral qu’elle avait espéré dans la perspective de la présidentielle de 2022. Comme en 2015\, la gauche entame une nouvelle traversée du désert au niveau régional. Absente du conseil depuis six ans\, son poids dans la région a encore baissé en 2021 pour se retrouver à l’étiage. En PACA\, comme dans nombre d’autres régions\, le scrutin régional a mis en évidence les faiblesses organisationnelles de LREM et l’absence d’implantation locale du parti présidentiel\, contraint de forger alliance avec la droite classique\, éléments essentiels d’une très probable candidature d’Emmanuel Macron à un second mandat. A droite\, enfin\, le psychodrame qui s’est joué autour de la constitution de la liste Muselier témoigne des difficultés de LR de se positionner aujourd’hui dans un espace politique entre LREM et le RN. La capacité des Républicains de résoudre cette équation stratégique sera\, à n’en pas douter\, une des clés de la présidentielle et\, pour ce qui concerne PACA\, des législatives.

Over the last decades\, molecular signatures have become increasingly important in oncology and are opening up a new area of personalized medicine. Nevertheless\, biological relevance and statistical tools necessary for the development of these signatures have been called into question in the literature. Here\, we investigate six typical selection methods for high-dimensional settings and survival endpoints\, including LASSO and some of its extensions\, component-wise boosting\, and random survival forests (RSF). A resampling algorithm based on data splitting was used on nine high-dimensional simulated datasets to assess selection stability on training sets and the intersection between selection methods. Prognostic performances were evaluated on respective validation sets. Finally\, one application on a real breast cancer dataset has been proposed. The false discovery rate (FDR) was high for each selection method\, and the intersection between lists of predictors was very poor. RSF selects many more variables than the other methods and thus becomes less efficient on validation sets. Due to the complex correlation structure in genomic data\, stability in the selection procedure is generally poor for selected predictors\, but can be improved with a higher training sample size. In a very high-dimensional setting\, we recommend the LASSO-pcvl method since it outperforms other methods by reducing the number of selected genes and minimizing FDR in most scenarios. Nevertheless\, this method still gives a high rate of false positives. Further work is thus necessary to propose new methods to overcome this issue where numerous predictors are present. Pluridisciplinary discussion between clinicians and statisticians is necessary to ensure both statistical and biological relevance of the predictors included in molecular signatures.
