Gallicagram est un nouvel outil de lexicométrie, fondé notamment sur les archives océrisées de la Bibliothèque nationale de France et sur celles du journal Le Monde ; il dénombre dans le corpus choisi et pour une période donnée les occurrences d’un mot ou d’un syntagme, et offre différents modes de visualisation des données obtenues. Ce logiciel mérite à plusieurs titres d’être investi par les chercheurs : outre le volume des données qu’il exploite, suffisant pour fonder des analyses lexicométriques depuis le (...) XVIIe siècle jusqu’à nos jours, Gallicagram a sur son concurrent immédiat, Ngram Viewer, l’avantage d’une transparence très supérieure et d’une structure plus constante au cours du temps. L’article présente Gallibase, son extension qui lui applique les outils de la statistique textuelle – en particulier les analyses factorielles et arborées. Il illustre son potentiel et insiste sur l’intérêt spécifique des corpus de presse, qui permettent des études sur périodes courtes. (shrink)

Résumé Dans l’Histoire d’une Grecque moderne de Prévost (1740), plusieurs traits de style apparentent l’écriture romanesque à la galanterie littéraire, emblématisée au siècle précédent par Racine ou Lafayette ; c’est le cas en particulier de l’association à l’article indéfini des expressions qui désignent le personnage féminin. Trait de genre (la nouvelle historique et galante), mais aussi d’époque (le long XVIIe siècle), ce tour devient sous la plume de Prévost un marqueur de son style d’auteur. Toutefois, sous l’apparence de la continuité, (...) la valeur et le sens de ce legs stylistique se voient reconfigurés de fond en comble : Prévost orchestre un véritable détournement du style galant. En récupérant l’un des traits par lesquels la langue galante signalait sa littérarité et en l’accommodant à ses propres enjeux romanesques, au risque d’en modifier la signification en profondeur, Prévost offre un cas d’école pour s’interroger sur la propriété des faits de style.

L'article explore la notion wébérienne de «domination rationnelle» comme outil pour analyser les rapports entre les efforts de gestion des populations indigènes par l'État colonial, et le développement d'une forme spécifique de rationalité scientifique, prenant pour objet ces populations: les savoirs anthropologiques. En s'appuyant sur le cas de l'Afrique coloniale française, on s'efforce de montrer comment les dimensions d'instrumentation (avec la production d'instruments d'identification et de compréhension) et de légitimation sont essentielles dans l'émergence de savoirs sur les sociétés et les (...) cultures indigènes, d'abord au sein des appareils administratifs, mais aussi dans les institutions savantes métropolitaines. L'appui au développement de la science de l'homme se fait dans le cadre de projets de « rationalisation » de la colonisation qui rapprochent des savants et des réformateurs liés à l 'École coloniale, voulant redéfinir la profession d'administrateur colonial comme «spécialiste des indigènes».

Laughter and yawning can both occur spontaneously and are highly contagious forms of social behavior. When occurring contagiously, laughter and yawning are usually confounded with a social situation and it is difficult to determine to which degree the social situation or stimulus itself contribute to its contagion. While contagious yawning can be reliably elicited in lab when no other individuals are present, such studies are more sparse for laughter. Moreover, laughter and yawning are multimodal stimuli with both an auditory and (...) a visual component: laughter is primarily characterized as a stereotyped vocalization whereas yawning is a predominantly visual signal and it is not known to which degree the visual and auditory modalities affect the contagion of laughter and yawning. We investigated how these two sensory modalities contribute to the contagion of laughter and yawning under controlled laboratory conditions in the absence of a social situation that might confound their contagion. Subjects were presented with naturally produced laughter and yawning in three sensory modalities, and we recorded their reaction to these stimuli. Contagious responses differed for laughter and yawning: overall, laughter elicited more contagious responses than yawning, albeit mostly smiling rather than overt laughter. While the audio-visual condition elicited most contagious responses overall, laughter was more contagious in the auditory modality, and yawning was more contagious in the visual modality. Furthermore, laughter became decreasingly contagious over time, while yawning remained steadily contagious. We discuss these results based on the ontogenetic and phylogenetic trajectories of laughter and yawning. (shrink)

Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

Deep learning and other black-box models are becoming more and more popular today. Despite their high performance, they may not be accepted ethically or legally because of their lack of explainability. This paper presents the increasing number of legal requirements on machine learning model interpretability and explainability in the context of private and public decision making. It then explains how those legal requirements can be implemented into machine-learning models and concludes with a call for more inter-disciplinary research on explainability.

Although "intrasexual selection" has been accepted as the mechanism by which males evolve elaborate secondary sexual traits which are used in aggressive contests, the importance of "intersexual selection" as a mechanism by which males have acquired exaggerated traits to display to females during courtship was less readily accepted. In spite of this scepticism, several genetic models have supported the latter idea, and many empirical studies showed that females were generally more discriminating in mate choice than males, because of differences in (...) relative investment between sexes. Nowadays, this idea is reinforced by various concepts (parental investment, potential reproductive rate, environmental potential for polygamy...) which stress that the strength of sexual selection is related to many interdependent factors, such as mating systems, resource distribution (food, habitat, mate), life history and other ecological characteristics. The case of Salmonids is presented here to show how novel information on sexual selection has contributed to the understanding of the plasticity of breeding patterns in the context of evolutionary biology.

During the past few years, the IRBIT domain has emerged as an important add‐on of S‐adenosyl‐L‐homocystein hydrolase (AHCY), thereby creating the new family of AHCY‐like proteins. In this review, we discuss the currently available data on this new family of proteins. We describe the IRBIT domain as a unique part of these proteins and give an overview of its regulation via (de)phosphorylation and proteolysis. The second part of this review is focused on the potential functions of the AHCY‐like proteins. We (...) propose that the IRBIT domain serves as an anchor for targeting AHCY‐like proteins towards cytoplasmic targets. This leads to regulation of (i) intracellular Ca2+ via the inositol 1,4,5‐trisphosphate receptor (IP3R), (ii) intracellular pH via the Na+/HCO3− cotransporters (NBCs); whereas inactivation of the IRBIT domain induces (iii) nuclear translocation and regulation of AHCY activity. Dysfunction of AHCY‐like proteins will disturb these three important functions, with various biological implications. BioEssays 30:642–652, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared against (...) experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

Benoit Mathot À partir du cadre théorique de la décoïncidence proposé par le philosophe François Jullien, cet article explore les enjeux d’humanisation des soins médicaux, ainsi que l’introduction de la dimension spirituelle dans la prise en charge des patients. Il revient enfin sur le dialogue possible entre ces réflexions contemporaines et les considérations du théologien luthérien Paul Tillich sur la santé.

Humanitarian organisations often work alongside those responsible for serious wrongdoing. In these circumstances, accusations of moral complicity are sometimes levelled at decision makers. These accusations can carry a strong if unfocused moral charge and are frequently the source of significant moral unease. In this paper, we explore the meaning and usefulness of complicity and its relation to moral accountability. We also examine the impact of concerns about complicity on the motivation of humanitarian staff and the risk that complicity may lead (...) to a retreat into moral narcissism. Moral narcissism is the possibility that where humanitarian actors inadvertently become implicated in wrongdoing, they may focus more on their image as self-consciously good actors than on the interests of potential beneficiaries. Moral narcissism can be triggered where accusations of complicity are made and can slew decision making. We look at three interventions by Médecins Sans Frontières that gave rise to questions of complicity. We question its decision-guiding usefulness. Drawing on recent thought, we suggest that complicity can helpfully draw attention to the presence of moral conflict and to the way International Non-Governmental Organisations can be drawn into unintentional wrongdoing. We acknowledge the moral challenge that complicity presents to humanitarian staff but argue that complicity does not help INGOs make tough decisions in morally compromising situations as to whether they should continue with an intervention or pull out.

This paper studies how in his Theory of Moral Sentiments Adam Smith answered to Mandeville on the role of pride and vanity in the economic and social dynamics of commercial societies. We show why vanity supersedes pride in his analysis and how he offers a more positive view of these two passions. We study in particular the economic and social consequences of pride and vanity and describe the psychological foundations of excessive self-esteem that these passions entail.

J'ai choisi de travailler un portrait de Bachelard pour retrouver son humanité, sa qualité de coeur, d'âme, ce qui est trop souvent absent dans les ouvrages traitant de ses travaux, ses livres. Fils de cordonnier, le chant des outils, le parfum des cuirs, l'attitude de l'artisan appliqué à faire et à parfaire son travail : le quotidien resta vivant en sa mémoire. Il n'avait pas oublié d'où il venait, l'admiration vient de là. Son humanité porte aussi la mort prématurée de (...) son épouse, Jeanne, le 20 juin 1920. Marié le 8 juillet 1914, mobilisé le 2 août de la même année jusqu'au 16 mars 1919, il a vécu 38 mois dans les tranchées. De leur union est née une fille, Suzanne. On peut dire qu'en dépassant ses peines, son deuil, il est devenu un fin guetteur de la beauté de vivre et du monde. La poésie a été pour lui une matière lui donnant de vibrer et respirer l'Univers. "La sagesse, dit-on, a pour origine et pour creuset de savoir lutter". Au long de son oeuvre, Bachelard a plaidé pour "la liberté, les hautes valeurs morales". En écrivant "Le visage de Bachelard", peu à peu, s'est instauré un dialogue, s'est imposée une façon de maïeutique ouvrant à des réflexions sur la vie, l'amitié, l'amour, agressivité, égocentrisme, haine, racisme, "la mauvaise foi" selon Sartre, "l'illusion" selon Pascal. En outre, il ressort en rapprochant plusieurs de leurs pensées que Gaston Bachelard et Léonard de Vinci étaient et restent en parenté de génie. Benoît Aubierge. (shrink)

During the course of evolution, variations of a protein sequence is an ongoing phenomenon however limited by the need to maintain its structural and functional integrity. Deciphering the evolutionary path of a protein is thus of fundamental interest. With the development of new methods to visualize high dimension spaces and the improvement of phylogenetic analysis tools, it is possible to study the evolutionary trajectories of proteins in the sequence space. Using the data-driven high-dimensional scaling method, we show that it is (...) possible to predict and represent potential evolutionary trajectories by representing phylogenetic trees into a 3D projection of the sequence space. With the case of the aminodeoxychorismate synthase, an enzyme involved in folate synthesis, we show that this representation raises interesting questions about the complexity of the evolution of a given biological function, in particular concerning its capacity to explore the sequence space.

The following article is the result of a collaboration between a painter and a woman philosopher. They worked previously on an experimental documentary film about objects and art objects, which was realized at Palais de Tokyo. The painter had illustrated in black and white fictions of philosophy, written during a festival on lost films organized by UNdocumenta in South Korea, and then he made photographs of oil paintings of the English translation. This article about painting and philosophical ethics is their (...) first common text. It aims to show that there is no interdiscipline or passage known between the philosophical work and the painting. The philosopher can not imitate the recognition of the painter nor the painter to repair the philosophical non-encounter. The question then is: What can ethics in this non-symmetrical space? Rather than being a product of philosophy, it is what organizes this space between recognition and non-encounter. It is an ethics for philosophy, rather than the other way around. Ethics force to greet the other philosophers without the grudge of the loss necessary to the invention and allows the painter to know the distances that make him feel the recognition. This ethical space is unknown and can not be covered by the artist's philosophy of access or pre-nomination by indexes. Ethics is this unknown, i.e. it is a sense-without-sign, it is without rules-said but process of indexation and acceptance of the loss. (shrink)

Cet article, en se référant à un passage des Confessions de Jean-Jacques Rousseau, tente d’analyser le surgissement dans l’écriture d’une œuvre d’architecture. On propose de nommer ce processus « architecturographie ».

Dans The Subjection of Women (1869), Mill fait bien plus que prôner l’égalité civique des hommes et des femmes : il entreprend une véritable révolution épistémologique pour déconstruire les représentations naturalisantes du caractère féminin. S’il compare d’abord la condition des femmes à celle des esclaves, c’est pour ensuite l’en distinguer, car la persistance de l’inégalité des sexes est en contradiction avec les principes juridiques des sociétés modernes. Il est donc attentif à la situation singulière du problème de l’assujettissement des femmes (...) : il ne s’agit pas de chercher à faire une « révolution sociale au nom d’un droit abstrait », mais de déraciner les préjugés qui expliquent la permanence archaïque de l’inégalité des sexes. C’est l’occasion d’une réflexion sur la construction de la domination patriarcale comme habitude sociale, par l’influence de l’éducation sur le caractère féminin. (shrink)

Grâce à une célèbre expérience de pensée impliquant un choix à effectuer entre deux paquets de cartes, Peirce estime avoir avancé un argument concluant en faveur de la thèse de l’enracinement social de la logique. Puisque cet argument repose sur une conception fréquentiste des probabilités, il va s’agir d’interroger cette conception et de se demander s’il est possible de défendre l’idée qu’il est rationnel pour un individu de fonder ses actions sur des estimations de probabilités sans avoir à endosser la (...) thèse peircienne de l’enracinement social de la logique. Après avoir souligné la réalité du problème soulevé par Peirce grâce à cette expérience de pensée et montré que le fréquentisme ne peut le résoudre, on se demandera si une conception propensionniste des probabilités pourrait y parvenir.
