The emergence of a `new' discourse on science in connection with events to do with the environment, food safety or public health has caused questions to be raised concerning the suitability of the triangular communication model generally applied to scientific popularization, i.e. in which there is an `intermediary' discourse plying between science and the general public. This `traditional' discourse would appear, then, to co-exist alongside the new discourse. The pragmatic functions of these two separate discourses on science are compared here (...) by looking at the linguistic and discursive variations which characterize their communicative and cognitive dimensions. In the new discourse on science, which has come to light over the past few years, the strict task of `popularizing' appears to have been dropped in favour of explaining the social stakes of the issues in question: thus the typically didactic and scientific nature of the cognitivo-discursive category, explanation can be seen to make way for a different type of explanation, which uses an interdiscursive memory bank built upon the productions of the mass media destined for the general public.

L’auteure exemplifie la notion de petit corpus à partir d’exemples de corpus « au vol » avant de montrer l’intérêt de saisir les premières tentatives de désignation d’un événement lorsqu’il surgit dans l’actualité médiatique (en 1.). Plusieurs petits corpus, réunis au fil d’instants discursifs qui s’inscrivent dans le traitement de la crise des migrants en Europe, permettent ensuite de mettre au jour le profil sémantique de mots représentatifs de cette crise à partir du repérage des constructions syntaxiques et des mots (...) qui leur sont associés en discours dans le contexte sociopolitique de 2015 à 2016 (en 2.). Ce qui permet de dégager un nouveau petit corpus, transversal aux précédents, autour de l’inscription d’une émotion, la peur, telle qu’elle est représentée dans le traitement médiatique de cette crise (en 3.).

RESUME Dans cet article, on aborde le champ de la vulgarisation scientifique en mettant l'accent sur les différentes sphères d'activité langagière qui s'y croisent. On rappelle d'abord le modèle classique et linéaire de la diffusion scientifique avant de montrer le déplacement qui s'est ensuite produit avec l'intervention des médias traditionnels, qui, notamment lors d'événements scientifiques, ont fait dialoguer différentes communautés langagières. On aborde enfin les changements apportés par les nouveaux outils technologiques dans des formes de participation et de prise de (...) parole qu'autorise l'internet.ABSTRACT This paper deals with the field of popular science with a focus on the different linguistic spheres that intersect it. It starts by reviewing the classical linear model of scientific dissemination. The authors then show the displacement that took place with the involvement of traditional media that established a dialogue between different language communities, in particular for scientific events. Finally, the changes to forms of participation and speech resulting from new technological tools and made possible by the Internet are presented.RESUMO O presente artigo aborda o campo da divulgação científica através das diferentes esferas de atividade linguageira que nele se cruzam. Evocaremos incialmente o modelo clássico e linear da divulgação científica, antes de apresentarmos o deslocamento produzido, em seguida, pela mídia tradicional, que possibilitou o diálogo entre diferentes comunidades linguageiras, especialmente em acontecimentos científicos. Mostraremos finalmente as modificações trazidas pelas novas ferramentas tecnológicas nas formas de participação e de tomada da palavra proporcionadas pela Internet. (shrink)

"Saturne, c'est ici l'Absolu de Hegel, un Absolu pensé si seul qu'il ne vit que de la perpétuelle dévoration de ses propres enfants, craignant d'être détrôné de son absoluité s'il n'absorbe pas, à mesure qu'il la produit, sa propre altérité. C'est cette solitude de Dieu qui est ici interrogée, en suivant au sein de l'oeuvre hégélien l'évolution, puis le plein déploiement conceptuel de la notion de Singularité, qui n'est autre que le nom divin par excellence. Si Dieu, l'Absolu, est pour (...) Hegel la Singularité même, ce n'est que parce qu'il est le mouvement de réflexion réciproque de l'Universel et du Particulier : l'Esprit est la réflexion du Logique dans la Nature, et de la Nature dans le Logique. Hegel ou Le Festin de Saturne se présente alors comme une enquête destinée à dévoiler le meurtre rituel dont la Singularité est le nom dans le Système hégélien. Or, cette Singularité, que nous sommes habitués à entendre individuelle, s'y révèle être boulimique ou, justement, saturnienne. S'ouvrant sur la faillite spéculative des singuliers sensibles au début de la Phénoménologie de l'Esprit, le présent ouvrage ne pourra se conclure qu'avec le triomphe de la Singularité dialectique ne laissant rien - pas même ou surtout pas son Autre - hors d'elle-même, lorsque ce triomphe sera mesuré à l'aune de la conceptualité chrétienne dont se revendique le protestant Hegel, mais qu'il trahit sur un point capital en voulant l'accomplir. Mais Saturne, c'est aussi le "soleil noir" des alchimistes, que l'on a pu associer au soleil obombré au moment de la mort du Christ : quoi de plus naturel, dès lors, que d'en faire l'astre tutélaire d'un système qui se construit tout entier autour d'un "Vendredi saint spéculatif"? Car, comme Dante dut traverser les neuf cercles de l'Enfer avant d'espérer pouvoir s'élever au Purgatoire, puis au Paradis, l'homme pensant doit traverser le Système de la Science, en subir peut-être les glaçantes tentations, en méditer en tous cas la fascinante rigueur conceptuelle, pour pouvoir ensuite espérer voir scintiller devant lui les lueurs matinales d'un inattendu "dimanche de Pâques spéculatif"."--Page 4 of cover.

The stratum-specific treatment effect function is a random variable giving the average treatment effect (ATE) for a randomly drawn stratum of potential confounders a clinician may use to assign treatment. In addition to the ATE, the variance of the stratum-specific treatment effect function is fundamental in determining the heterogeneity of treatment effect values. We offer a non-parametric plug-in estimator, the targeted maximum likelihood estimator (TMLE) and the cross-validated TMLE (CV-TMLE), to simultaneously estimate both the average and variance of the stratum-specific (...) treatment effect function. The CV-TMLE is preferable because it guarantees asymptotic efficiency under two conditions without needing entropy conditions on the initial fits of the outcome model and treatment mechanism, as required by TMLE. Particularly, in circumstances where data adaptive fitting methods are very important to eliminate bias but hold no guarantee of satisfying the entropy condition, we show that the CV-TMLE sampling distributions maintain normality with a lower mean squared error than TMLE. In addition to verifying the theoretical properties of TMLE and CV-TMLE through simulations, we highlight some of the challenges in estimating the variance of the treatment effect, which lack double robustness and might be biased if the true variance is small and sample size insufficient.

“Neural coding” is a popular metaphor in neuroscience, where objective properties of the world are communicated to the brain in the form of spikes. Here I argue that this metaphor is often inappropriate and misleading. First, when neurons are said to encode experimental parameters, the neural code depends on experimental details that are not carried by the coding variable. Thus, the representational power of neural codes is much more limited than generally implied. Second, neural codes carry information only by reference (...) to things with known meaning. In contrast, perceptual systems must build information from relations between sensory signals and actions, forming an internal model. Neural codes are inadequate for this purpose because they are unstructured and therefore unable to represent relations. Third, coding variables are observables tied to the temporality of experiments, whereas spikes are timed actions that mediate coupling in a distributed dynamical system. The coding metaphor tries to fit the dynamic, circular, and distributed causal structure of the brain into a linear chain of transformations between observables, but the two causal structures are incongruent. I conclude that the neural coding metaphor cannot provide a valid basis for theories of brain function, because it is incompatible with both the causal structure of the brain and the representational requirements of cognition.

Essai général sur le philosophe et prosateur chinois Tchouang-Tseu dont l'oeuvre se situe à l'origine du taoïsme philosophique et religieux. Ses leçons métaphysiques, son ironie contre toute forme d'autorité s'épanouissent sous forme de dialogues, fables et historiettes que l'auteur interprète et commente pour en dégager les enjeux.

Inner speech has been shown to vary in form along several dimensions. Along condensation, condensed inner speech forms have been described, that are supposed to be deprived of acoustic, phonological and even syntactic qualities. Expanded forms, on the other extreme, display articulatory and auditory properties. Along dialogality, inner speech can be monologal, when we engage in internal soliloquy, or dialogal, when we recall past conversations or imagine future dialogues involving our own voice as well as that of others addressing us. (...) Along intentionality, it can be intentional (when we deliberately rehearse material in short-term memory) or it can arise unintentionally (during mind wandering). We introduce the ConDialInt model, a neurocognitive predictive control model of inner speech that accounts for its varieties along these three dimensions. ConDialInt spells out the condensation dimension by including inhibitory control at the conceptualization, formulation or articulatory planning stage. It accounts for dialogality, by assuming internal model adaptations and by speculating on neural processes underlying perspective switching. It explains the differences between intentional and spontaneous varieties in terms of monitoring. We present an fMRI study in which we probed varieties of inner speech along dialogality and intentionality, to examine the validity of the neuroanatomical correlates posited in ConDialInt. Condensation was also informally tackled. Our data support the hypothesis that expanded inner speech recruits speech production processes down to articulatory planning, resulting in a predicted signal, the inner voice, with auditory qualities. Along dialogality, covertly using an avatar’s voice resulted in the activation of right hemisphere homologues of the regions involved in internal own-voice soliloquy and in cerebellar deactivation, consistent with internal model adaptation. Switching from first-person to third-person perspective resulted in activations in precuneus and parietal lobules. Along intentionality, compared with intentional inner speech, mind wandering with inner speech episodes was associated with greater bilateral inferior frontal activation and decreased activation in left temporal regions. This is consistent with the reported subjective evanescence and presumably reflects condensation processes. Our results provide neuroanatomical evidence compatible with predictive control and in favor of the assumptions made in the ConDialInt model. (shrink)

Romain Rolland (1866-1944), écrivain, dramaturge, historien et musicologue, est l'auteur d'une oeuvre considérable et variée. La Grande Guerre fut pour lui l'occasion d'une méditation sur la violence et la haine, et le désastre qui s'abattit sur l'Europe, méditation qui aboutira à la rédaction d'Au-dessus de la mêlée (1914). Ce manifeste pacifiste, lucide et passionné, contribua à l'obtention, par l'auteur déjà célèbre de Jean-Christophe, Beethoven, La vie de Tolstoï, Danton, Les Loups, etc, du prix Nobel de littérature (1915). Son oeuvre (...) se caractérise par la recherche d'une harmonie universelle, de paix et de justice. Empédocle (1918) et L'éclair de Spinoza (1924) sont une expression "enthousiaste" de gratitude envers deux immenses penseurs, compagnons de route de Rolland, qui en a subi la profonde et durable influence. Il s'y révèle un styliste de grande classe, poète original en même temps que rigoureux penseur et pédagogue. (shrink)

Ce livre a été publié en 1929. Il est le premier tome de l'Essai sur la mystique et l'action de l'Inde vivante, le deuxième tome étant La vie de Vivekananda et l'évangile universelpublié en 1930. Il présente la vie et la pensée d'un des plus grands sages de l'Inde : Ramakrishna. Ramakrishna est un saint du Bengale né en 1836 à Calcutta et mort dans cette même ville en 1886. Ramakrishna enseignait que toutes les religions recherchent le même but : (...) l'union avec Dieu. Proche de l'Islam, du Christianisme et bien que profondément hindou, il a cherché à faire une synthèse des religions. Son message demeure plus que jamais d'actualité. (shrink)

The neural coding metaphor is so ubiquitous that we tend to forget its metaphorical nature. What do we mean when we assert that neurons encode and decode? What kind of causal and representational model of the brain does the metaphor entail? What lies beneath the neural coding metaphor, I argue, is a bureaucratic model of the brain.

Psychiatry is becoming a cognitive neuroscience. This new paradigm not only aims to give new ways for explaining mental diseases by naturalizing them, but also to have an influence on different levels of psychiatric norms. We tried here to verify whether a biological paradigm is able to fulfill this normative goal. We analyzed three main normative assumptions that is to say the will of giving psychiatry a valid nosology, a rigorous definition of what is a mental disease, and new tools (...) for destigmatizing mentally ill patients. Although these different kinds of normativity are very heterogeneous, we must conclude that, in all these cases, biological psychiatry is a failure, in part because of a lack of epistemological conceptualization.

This paper shows that low-level generalisations in argument structure constructions are crucial to understanding the concept of alternation: low-level generalisations inform and constrain more schematic generalisations and thus constructional meaning. On the basis of an analysis of the causative alternation in English, and more specifically of the theme, I show that each construction has its own schematic meaning. This analysis is conducted on a dataset composed of 11,554 instances of the intransitive non-causative construction and the transitive causative construction. The identification (...) of lower-level generalisations feeds into the idea that language acquisition is organic and abstractions are formed only gradually from exposure to input. So far, most of the literature on argument structure constructions has focused on the verb itself, and thus fails to capture these generalisations. I make up for this deficit through an in-depth analysis of the causative alternation. (shrink)

Avec l'extension du domaine du risque, consecutive aux avancees technologiques de tous ordres et a l'amplification des echanges a l'echelle planetaire, chacun porte desormais une responsabilite etendue, dans l'espace et le temps. Cette situation inedite, generatrice de nouveaux questionnements ethiques, met en lumiere un paradoxe: bien qu'essentielle dans un tel contexte, la notion de responsabilite semble avoir perdu de son sens et de sa clarte, comme dissimulee derriere la multiplicite de ses occurrences. Il devient ainsi decisif d'interroger a nouveau ce (...) concept: qu'est-ce que la responsabilite? Comment prendre une decision responsable face aux dilemmes moraux, juridiques, economiques, environnementaux, politiques, sociaux et societaux? Analysant a la fois les fondements philosophiques de la responsabilite et ses recentes metamorphoses, cet essai introduit autant a l'ethique appliquee, notamment dans le domaine des affaires et du management, qu'il suggere une nouvelle forme de sagesse pratique, singuliere et incarnee, centree sur l'exercice quotidien de vertus adaptees aux enjeux du monde contemporain.

Written in the early 1990s by a winner of the Nobel Prize in Literature.

This is a new release of the original 1930 edition.

To make the voice heard of those for whom the written word is not part of their cultural tradition is Romaine Moreton’s project as Aboriginal poetess and performer. We publish here two poems from her collection Post Me to the Prime Minister. Flowing by the beat of the bongo, originally written in English, manoeuvering between the written language of the colonisator and the music of the colonised, they forcefully express Romaine Moreton’s struggle : the combat of a people for the (...) right to represent itself and to be the author of its own existence.

Integrated information theory postulates that a conscious experience depends on a repertoire of hypothetical experiences. This makes consciousness depend on the context that constrains the set of possibilities and on the scenarios imagined by the external observer, and not only on the system itself.

Dans le contexte de la réaction romaine aux guerres de religion françaises, Giovanni Botero, premier théoricien de la raison d’État, effectue une opération originale : il place la question économique au cœur même de la pensée politique et de la théorie de l’État. L’enjeu est de définir une pensée de l’État entièrement fondée sur une idée de puissance qu’il oppose explicitement au concept de souveraineté. Contre la nouvelle théorisation juridico-politique d’origine française qui ne cesse de se répandre en Europe, Botero (...) propose ainsi un modèle politique qui allie l’analyse machiavélienne des rapports de forces et l’étude des conditions du développement économique des États.

The Zhuangzi is one of China's greatest literary and philosophical masterpieces, yet its complexities make it a challenging read. This English translation leads you confidently through the comic scenes and virtuoso writing style, introducing all the little stories Zhuangzi invented and unpicking its philosophy through close commentaries and helpful asides. In Graziani's translation, the co-founder of Daoism emerges as a remarkable thinker. It is a must-read for anyone coming to Chinese philosophy or the Zhuangzi for the first time, and one (...) that reminds us of the importance of thinking beyond our limited, everyday perspectives.

Transcranial alternating-current stimulation in the frequency range of 1–100 Hz has come to be used routinely in electroencephalogram studies of brain function through entrainment of neuronal oscillations. It turned out, however, to be highly non-trivial to remove the strong stimulation signal, including its harmonic and non-harmonic distortions, as well as various induced higher-order artifacts from the EEG data recorded during the stimulation. In this paper, we discuss some of the problems encountered and present methodological approaches aimed at overcoming them. To (...) illustrate the mechanisms of artifact induction and the proposed removal strategies, we use data obtained with the help of a schematic demonstrator setup as well as human-subject data.

The role of the major histocompatibility complex (MHC) in mate choice in humans is controversial. Nowadays, the availability of genetic variation data at genomic scales allows for a careful assessment of this question. In 2008, Chaix et al. reported evidence for MHC‐dependent mate choice among European American spouses from the HapMap 2 dataset. Recently, Derti et al. suggested that this observation was not robust. Furthermore, when Derti et al. applied similar analyses to the HapMap 3 European American samples, they did (...) not see a significant effect. Although some of the points raised by Derti et al. are relevant, we disagree with the reported absence of evidence for MHC‐dependent mate choice within the HapMap samples. More precisely, we show here that the MHC dissimilarity among HapMap 3 European American spouses is still extreme in comparison to the rest of the genome, even after multiple testing correction. This finding supports the hypothesis of MHC‐dependent mate choice in some human populations. (shrink)

In these three Indian biographies dating from the 1920s, Romain Rolland introduces the French reader to Gandhi's political struggle and to the spiritual careers of Ramakrishna and his disciple Vivekananda, while revealing the deep meaning of his attraction to Hindu India at this time of his life.

Focusing on the reception of Maine de Biran by Alexis Bertrand in his thesis, L’aperception du corps humain par la conscience (1880), I will demonstrate how the “corps propre” (one’s own body) becomes a key concept in order to re-orientate the French spiritualist movement. To do so, Bertrand’s neo-Biranism uses a new methodology with phenomenological issues. The image of the body, the primitive space or the engagement within the world becomes new research themes for spiritualism. His interpretation of Biran’s philosophy (...) leads him to criticize mechanistic epistemology, and especially the concept of reflex. In this context, Bertrand proposes an animist metaphysics, aiming to reconcile his Biranism with the advances of science. As a consequence, the history of the concept of one’s own body must take into account metaphysical perspectives and not only scientific and experimental researches. (shrink)
