Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. (...) 1) Some theories posit that symbolic language originated in a gestural modality, as in “sign languages”. However, this overlooks work on emerging sign and spoken language showing that gestures and speech shape signs differently. 2) In modality-dependent theories, some emphasize the role of iconic sounds, though these lack the efficiency of arbitrary symbols. Other theorists suggest that ontogenesis serves to identify human-specific mechanisms underlying an evolutionary shift from pitch varying to orally-modulated vocalizations (babble). This shift creates numerous oral features that can support efficient symbolic associations. We illustrate this principle using a sound-picture association task with 40 learners who hear words in an unfamiliar language (Mandarin) with and without a filtering of oral features. Symbolic associations arise more rapidly and accurately for sounds containing oral features compared to sounds bearing only pitch features, an effect also reported in experiments with infants. The results imply that, beyond a competence to learn and use symbols, the rise of symbolic language rests on the types of signs that a modality of expression affords. (shrink)

Research on bilingualism has grown exponentially in recent years. However, the comprehension of speech in noise, given the ubiquity of both bilingualism and noisy environments, has seen only limited focus. Electroencephalogram studies in monolinguals show an increase in alpha power when listening to speech in noise, which, in the theoretical context where alpha power indexes attentional control, is thought to reflect an increase in attentional demands. In the current study, English/French bilinguals with similar second language proficiency and who varied in (...) terms of age of L2 acquisition from 0 to 15 years completed a speech perception in noise task. Participants were required to identify the final word of high and low semantically constrained auditory sentences such as “Stir your coffee with a spoon” vs. “Bob could have known about the spoon” in both of their languages and in both noise and quiet during electrophysiological recording. We examined the effects of language, AoA, semantic constraint, and listening condition on participants’ induced alpha power during speech comprehension. Our results show an increase in alpha power when participants were listening in their L2, suggesting that listening in an L2 requires additional attentional control compared to the first language, particularly early in processing during word identification. Additionally, despite similar proficiency across participants, our results suggest that under difficult processing demands, AoA modulates the amount of attention required to process the second language.

A One Health approach holds great promise for attenuating the risk and burdens of emerging infectious diseases (EIDs) in both human and animal populations. Because the course and costs of EID outbreaks are difficult to predict, One Health policies must deal with scientific uncertainty, whilst addressing the political, economic and ethical dimensions of communication and intervention strategies. Drawing on the outcomes of parallel Delphi surveys conducted with policymakers in Singapore and Australia, we explore the normative dimensions of two different precautionary (...) approaches to EID decision-making—which we call regimes of risk management and organizing uncertainty, respectively. The imperative to act cautiously can be seen as either an epistemic rule or as a decision rule, which has implications for how EID uncertainty is managed. The normative features of each regime, and their implications for One Health approaches to infectious disease risks and outbreaks, are described. As One Health attempts to move upstream to prevent rather than react to emergence of EIDs in humans, we show how the approaches to uncertainty, taken by experts and decision-makers, and their choices about the content and quality of evidence, have implications for who pays the price of precaution, and, thereby, social and global justice.

Friendship was an important topic for classical philosophers; the analysis, Value, And duties of friendship all received considerable attention. But friendship has been a relatively dormant topic among more recent philosophers. This paper (a) presents an analysis of friendship and explains its core elements, (b) discusses several different models for explaining the value of friendship, And (c) argues that there are special duties of friendship and that these aren't based solely on utilitarian considerations.

Dopamine is critically important in the neural manifestation of motivated behavior, and alterations in the human dopaminergic system have been implicated in the etiology of motivation-related psychiatric disorders, most prominently addiction. Patients with chronic addiction exhibit reduced dopamine D2 receptor (DRD2) availability in the striatum, and the DRD2 TaqIA (rs1800497) and C957T (rs6277) genetic polymorphisms have previously been linked to individual differences in striatal dopamine metabolism and clinical risk for alcohol and nicotine dependence. Here, we investigated the hypothesis that the (...) variants of these polymorphisms would show increased reward-related memory formation, which has previously been shown to jointly engage the mesolimbic dopaminergic system and the hippocampus, as a potential intermediate phenotype for addiction memory. To this end, we performed functional magnetic resonance imaging (fMRI) in 62 young, healthy individuals genotyped for DRD2 TaqIA and C957T variants. Participants performed an incentive delay task, followed by a recognition memory task 24 h later. We observed effects of both genotypes on the overall recognition performance with carriers of low-expressing variants, namely TaqIA A1 carriers and C957T C homozygotes, showing better performance than the other genotype groups. In addition to the better memory performance, C957T C homozygotes also exhibited a response bias for cues predicting monetary reward. At the neural level, the C957T polymorphism was associated with a genotype-related modulation of right hippocampal and striatal fMRI responses predictive of subsequent recognition confidence for reward-predicting items. Our results indicate that genetic variations associated with DRD2 expression affect explicit memory, specifically for rewarded stimuli. We suggest that the relatively better memory for rewarded stimuli in carriers of low-expressing DRD2 variants may reflect an intermediate phenotype of addiction memory. (shrink)

The Mental Health Literacy Scale is the most widely used and strong theory-based measurement tool to gain an understanding of mental health knowledge and ability. This study aimed to test the psychometric properties of the Chinese version of the Mental Health Literacy Scale and to document the norm and its influential factors of mental health literacy among nurses. The MHLS was translated following Brislin’s translation model and tested with a sample of 872 clinical registered nurses. The Jefferson Scale of Empathy-Health (...) Professionals, Patient Health Questionnaire-2, and Generalized Anxiety Disorder-2 were administered to assess convergent validity. The minimum average partial test, parallel analysis and confirmatory factor analysis supported 4 first-order 2 second-order structure. The 4 factors were named “knowledge of mental disorder,” “ability to seek information and help,” “recognition of mental disorder,” and “acceptance of patients with mental illness,” with factor 1-3 were summarized into MHLS-Core and factor 4 as MHLS-SA. The MHLS-C was moderately negatively correlated with the PHQ-2 and GAD-2 and highly positively correlated with JSE-HP. The Cronbach’s α was 0.85 for the overall scale and 0.89 and 0.93 for two subscales. The test-retest reliability was good, with intraclass correlation coefficients of 0.80 for the whole scale, and 0.79 and 0.94 for two subscales. As an approximately normal distribution, the 50th percentile for the MHLS-C was 99, with 50th percentiles of 74 and 20 for MHLS-Core and MHLS-SA. Higher position, higher professional credentials, higher hospital hierarchy, other specialist hospital, psychiatric hospital and unmarried status were positive predictors. The 29-item MHLS-C, with two subscales of MHLS-Core and MHLE-SA, is a stable and validated tool to measure mental health literacy. MHLS-Core could be used independently to measure the core content of mental health literacy. It may be applicable for Chinese health professionals, but need further validation among the general public. MHL curriculum and a targeted culturally appropriate program for acceptance for health professionals, especially for those in general hospitals and with less working tenure, may be recommended.

On connaît peu la pensée chinoise contemporaine. Annie Boisclair s'intéresse ici tout particulièrement au philosophe Mou Zongsan (1909-1995) au parcours singulier. D'origine modeste, il quitte le milieu rural de Shandong pour aller étudier à l'université de Pékin en 1929. Juste avant la prise du pouvoir par les communistes en 1949, Mou fuit à Taïwan puis, plus tard, à Hong Kong. Il enseignera dans diverses universités et les turbulences sociales et politiques de la Chine seront intimement liées à l'approfondissement de (...) sa connaissance de la tradition intellectuelle chinoise qu'il mettra en relation avec les courants philosophiques occidentaux. C'est le dialogue entre les deux traditions et leur fécondation mutuelle que Annie Boisclair fait apparaître en suivant la pensée du philosophe. De tous les penseurs de ce courant, peu ont eu autant d'influence que Mou Zongsan. Mou supposait que les Chinois subiraient une perte d'identité culturelle s'ils ne valorisaient que le savoir étranger et, en même temps, que la civilisation chinoise ne survivrait pas à un enfermement sur elle-même. La pensée de Mou intégrait déjà plusieurs traditions fondamentales chinoises comme le confucianisme, le taoïsme et le bouddhisme, il était donc naturel d'y inclure des courants de philosophie occidentale. Rarement traduit en français, l'auteure propose en annexe de l'ouvrage quelques pages du philosophe. (shrink)

Le fragment d'épinétron 907 du Musée d'Eleusis représente une Amazone sonnant de la trompette et appelant ses compagnes aux armes ; elle est entourée de lettres jusqu'à présent considérées comme dépourvues de sens : TOTOTETO(T)H. Ces syllabes appartiennent en réalité à une notation musicale de type « solfégique » qui ne nous était connue jusqu'ici que par des théoriciens postérieurs au IIe siècle ap.

En 1981-82 Foucault a consacré son enseignement au Collège de France à la question du souci de soi antique. À ce cours, publié en 2001, il a donné le titre énigmatique d’«Herméneutique du sujet».

Mon but consiste donc à montrer que si (...) le dernier Foucault s’est concentré sur le souci de soi antique, c’était en vue d’opposer une résistance à la tendance contemporaine à l’herméneutique de soi.

On one of the reliefs in the famous Passage of the Theoria Apollo is depicted holding aloft a cithara, all of whose parts, detached from the wall, are today broken (left upright strut above the crosspiece and the whole right-hand section of the instrument). If a reconstruction drawing of how the complete cithara originally looked is made on the basis of the surviving elements, it can be seen that it is more squat and less high than similar instruments generally are, (...) a large number of which are depicted on red-figure vases, with the dates usually proposed by sculpture experts to place the Theoria relief in a chronological context. The cithara that we see is closer in its proportions to the slightly earlier ones which appear on black-fîgure pottery at around 490 B. C. The form and type of the Theoria cithara thus argue in favour of a high date for the whole monument. (shrink)

La voix féminine dans l’œuvre lyrique mozartienne chante sur un unique registre, le registre aigu. Tous les personnages féminins possèdent une voix unique : celle du soprano ; par contre, la voix masculine, elle, chante sur deux registres : aigu et grave. Cette séparation sexuée des voix qui apparaît pour la première fois dans l’histoire de l’opéra avec Mozart délimite nettement, côté masculin, des rôles bien séparés : ceux des fils - ténor, registre aigu - et ceux des pères - (...) basse, registre grave -. Par contre, côté féminin, les rôles sont confondus ; jeunes filles, épouses, sœurs, mères, duègnes, non seulement possèdent une commune tessiture mais s’expriment musicalement, très souvent, de la même manière : la grande aria virtuose. C’est à travers le personnage de la mère et en particulier celui de la Reine de la Nuit dans La Flûte enchantée, que nous avons tenté de comprendre le pourquoi de cette voix unique de la féminité selon Mozart. Le fil de cette voix féminine est noué avec le fil d’une autre voix qui résonne dans la correspondance mozartienne, celle de la mère de Mozart, Anna-Maria. La mise en relation de l’œuvre et de la biographie détient, peut-être, la clé - musicale - de l’énigme. (shrink)

La notion de « populisme » s'est complètement transformée au cours du temps. Valorisant hier le populaire, elle le stigmatise aujourd'hui. Les usages actuels du «populisme du FN» en témoignent. S'ils font désormais consensus pour désigner dans les groupes populaires les principaux soutiens du parti frontiste, c'est au prix d'une naturalisation des interprétations du succès politique du FN oubliant le rôle des élites politiques et sociales, au prix également d'un changement de perspective sur l'autoritarisme et la signification concrète de l'appel (...) au peuple dans l'histoire sociale de la construction des démocraties.The meaning of the notion of "populism" has thoroughly changed over time. While in the past it was used in order to celebrate people's, it nowadays is used in order to stigmatize it. Current uses of the notion of the "populism of the Front National" give testimony to this change, for they help put forward the idea that the main constituency of this party is made of the "lower classes". But this hypothesis has a high analytical cost, for it implies that the interpretation of the political success of the Front National is then seen as taken-for-granted. Hence, nothing is said anymore about the role played in this success by social and political elites. Moreover, putting the blame of the renewal of hatred-prone "populism" on people's politics is a way to dangerously shift the perspective on the social history of the process of the building of modern democracies by erasing the role played by people's mobilizations.

ANNIE HOURCADE SCIOU | : Cette étude entend montrer que la bientraitance correspond à une démarche volontaire d’assumer notre responsabilité vis-à-vis de la vulnérabilité de l’autre et en constitue la réponse la plus adaptée. La vulnérabilité, en effet, revêt une dimension essentiellement relationnelle et non substantielle. Comme en témoigne l’étymologie du terme, être vulnérable, c’est être susceptible d’être blessé, à la différence de la fragilité, qui, pour sa part, correspond à une faiblesse intrinsèque. La vulnérabilité, dans sa dimension relationnelle, (...) peut être rapprochée de la dépendance. En ce sens, plus que la bienfaisance qui s’inscrit dans une visée téléologique, celle qui consiste à produire le bien de l’autre, la bientraitance porte sur la manière d’agir sur l’autre en situation de vulnérabilité, sur la nature même de la relation dont nous sommes directement parties prenantes. | : This study aims to show that « bientraitance » constitutes a voluntary approach to undertake our responsibility for the other’s vulnerability and is the more appropriate response to it. Vulnerability takes on a relative and non substantial dimension, as shown by its etymology. As a matter of fact, being vulnerable means being exposed to the possibility of been harmed, unlike fragility which, as far as it is concerned, is an intrinsic deficiency. Vulnerability, in its relational dimension, may be compared to dependence. Unlike beneficence, which is part of a teleological perspective, which aims to produce the other’s good, « bientraitance » concerns how we act on the other in situation of vulnerability, on the very nature of the relationship in which we are directly implicated.

Spatial and temporal heterogeneity are often described as important factors having a strong impact on biodiversity. The effect of heterogeneity is in most cases analyzed by the response of biotic interactions such as competition of predation. It may also modify intrinsic population properties such as growth rate. Most of the studies are theoretic since it is often difficult to manipulate spatial heterogeneity in practice. Despite the large number of studies dealing with this topics, it is still difficult to understand how (...) the heterogeneity affects populations dynamics. On the basis of a very simple model, this paper aims to explicitly provide a simple mechanism which can explain why spatial heterogeneity may be a favorable factor for production. We consider a two patch model and a logistic growth is assumed on each patch. A general condition on the migration rates and the local subpopulation growth rates is provided under which the total carrying capacity is higher than the sum of the local carrying capacities, which is not intuitive. As we illustrate, this result is robust under stochastic perturbations. (shrink)

The authors propose a reflection on the construction of professional identity in a context of institutional crisis.

Therefore, the teacher has to build its (...) identity from a set of rational narrative experience of professional practice.contrastée des attentes et des représentations d'étudiants en formation initiale à l'enseignement secondaire en fonction de leur engagement ou non dans un établissement scolaire Cet article présente les résultats d’une recherche menée auprès d’enseignants du niveau secondaire au Québec, plus spécifiquement dans la région de la Mauricie.

This now-classic work challenges what Ryle calls philosophy's "official theory," the Cartesians "myth" of the separation of mind and matter. Ryle's linguistic analysis remaps the conceptual geography of mind, not so much solving traditional philosophical problems as dissolving them into the mere consequences of misguided language. His plain language and esstentially simple purpose place him in the traditioin of Locke, Berkeley, Mill, and Russell.

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

Mastery imagery (i.e., images of being in control and coping in difficult situations) is used to regulate anxiety. The ability to image this content is associated with trait confidence and anxiety, but research examining mastery imagery ability's association with confidence and anxiety in response to a stressful event is scant. The present study examined whether trait mastery imagery ability mediated the relationship between confidence and anxiety, and the subsequent associations on performance in response to an acute psychological stress. Participants (N= (...) 130; 55% male;Mage= 19.94 years;SD= 1.07 years) completed assessments of mastery imagery ability and engaged in a standardized acute psychological stress task. Immediately prior to the task, confidence, cognitive and somatic anxiety intensity, and interpretation of anxiety symptoms regarding the task were assessed. Path analyses supported a model whereby mastery imagery ability mediated the relationship between confidence and cognitive and somatic anxiety interpretation. Greater mastery imagery ability and confidence were both directly associated with better performance on the stress task. Mastery imagery ability may help individuals experience more facilitative anxiety and perform better during stressful tasks. Improving mastery imagery ability by enhancing self-confidence may help individuals successfully cope with anxiety elicited during stressful situations. (shrink)

Les rencontres avec les travaux d'Anne-Françoise Schmid que présente cet ouvrage, mettent la philosophie générique au coeur des pratiques contemporaines des sciences, ouvrant ainsi une nouvelle voie pour la création épistémologique. Comment produire une description non disciplinaire des sciences? Qu'est-ce qui permet aux sciences d'être conceptives? - De quoi a-t-on besoin pour une science sans exclusions? Quels sont les nouveaux opérateurs de rigueur des sciences contemporaines? Les travaux d'Anne-Françoise Schmid montrent que les objets contemporains des sciences ne se prêtent pas (...) à des définitions standard, et que les convergences de perspectives disciplinaires ne permettent pas non plus d'assurer un point de vue théorique unifié, mais seulement des trajectoires particulières et multiples. Il n'y a pas d'objet sans rapport à l'objet. Ce rapport n'est pas simplement une mise en contexte, elle met en jeu l'intime et l'intention des chercheurs. Les disciplines cachent cet aspect. Sa philosophie travaille à la mise en lumière des opérations qui permettent l'ouverture d'un espace générique : c'est-à-dire un espace qui ne dépend pas d'une seule discipline et qui est condition d'une nouvelle mise en relation des concepts d'humain et de sciences. Les contributions de cet ouvrage mettent en évidence des nouvelles logiques de découpage, de réarticulation et d'invention de concepts dans une grande diversité de champs disciplinaires. Ce livre offre une entrée dans un espace générique. Le générique permet de voir ainsi ce que l'on ne voit pas avec l'épistémologie classique."--Page 4 of cover. (shrink)

The article Deflating the "DBS causes personality changes" bubble, written by Frederic Gilbert, J. N. M. Viaña and C. Ineichen, was originally published electronically on the publisher’s internet portal on 19 June 2018 without open access.

To conclude that there is enough or not enough evidence demonstrating that deep brain stimulation causes unintended postoperative personality changes is an epistemic problem that should be answered on the basis of established, replicable, and valid data. If prospective DBS recipients delay or refuse to be implanted because they are afraid of suffering from personality changes following DBS, and their fears are based on unsubstantiated claims made in the neuroethics literature, then researchers making these claims bear great responsibility for prospective (...) recipients' medical decisions and subsequent well-being. Our article “Deflating the ‘DBS causes personality’ bubble” reported an increase in theoretical neuroethics publications suggesting putative DBS-induced changes to personality, identity, agency, autonomy, authenticity and/or self and a critical lack of supporting primary empirical studies. This special issue of Neuroethics brings together responses to our initial publication, with our own counter-responses organized according to common themes. We provide a brief summary for each commentary and its main criticisms as well as a discussion of the way in which these responses can: 1) help clarify the meaning of PIAAAS, suggesting supplementary frameworks for understanding the impact of DBS on PIAAAS; 2) provide further empirical evidence of PIAAAS by presenting results from the researchers’ own work; and/or 3) offer a critique of our research approach and/or findings. Unintended postoperative putative changes to PIAAAS remain a critical ethical concern. It is beyond dispute that we need to develop reliable empirical and conceptual instruments able to measure complex cognitive, affective, and behavioural changes in order to investigate whether they are attributable to DBS alone.

In his treatment of Marius in the Bellum Jugurthinum Sallust lays considerable stress on fortune2 and Marius' belief in divine assistance. I shall offer an analysis of these concepts in two sections: their use by Sallust himself in relation to Marius; their use in the earlier tradition about Marius.I. Though he is frequently mentioned in the earlier chapters of the B.J., our first formal introduction to Marius is in chapter 63. This chapter is of crucial importance. For it is the (...) response given by the haruspex to Marius when he chances to be making a sacrifice at Utica that prompts him to ask for leave to go and stand for the consulship, an office for which he has an ingens cupido. Because of the aristocratic superbia of his commander Metellus he is ‘snubbed’ by him and thenceforth ‘cupidine atque ira grassari; neque facto ullo neque dicto abstinere quod modo ambitiosum foret'.

A new realislic local model of light propagation and detection is described. The authors propose a novel stochastic model of low-intensity photon detection in which background noise is added to a part of the photon prior to absorption. In this model, in agreement with Planck, there is no quantization of the propagating field. The model has some similarities to theories advanced by E. Santos and T. Marshall in the last decade, but also has substantial deviations from these. A mechanism, conserving (...) energy and momentum, is proposed by which a sudden collapse of the wave-packet is avoided. The experimental Bell inequality violation of Aspect. Grangier and Roger [Phys. Rev. Lett.47, 460 (1981)]is discussed. The authors have carried out a computer simulation of a radio frequency (RF) analogue of the Einstein-Podolsky-Rosen thought experiment to illustrate how the manipulation of certain factors, especially signal to noise ratio, detector threshold and characteristics of the noise, enables the same Bell inequality to be either satisfied or violated by a realistic local model. Building on arguments by Santos. [Phys. Rev. A46. 3646 (1992)],the appropriateness of this Bell lest is discussed. Neither the authors' stochastic-optical model, nor their RF analogue, involves an enhancement assumption of the type defined by Clauser and Horne [Phys. Rev. D10, 526 (1974)]. (shrink)
