Successful surgical treatment of patients with focal drug-resistant epilepsy remains challenging, especially in cases for which it is difficult to define the area of cortex from which seizures originate, the seizure onset zone. Various diagnostic methods are needed to select surgical candidates and determine the extent of resection. Interictal magnetoencephalography with source imaging has proven to be useful for presurgical evaluation, but the use of ictal MEG data remains limited. The purpose of the present study was to determine whether pre-ictal (...) variations of spectral properties of neural activity from ictal MEG recordings are predictive of SOZ location.We performed a 4 h overnight MEG recording in an 8-year-old child with drug-resistant focal epilepsy of suspected right fronto-temporal origin and captured one ~45-s seizure. The patient underwent a right temporal resection from the anterior temporal neocortex and amygdala to the mid-posterior temporal neocortex, sparing the hippocampus proper. She remains seizure-free 21 months postoperatively. The histopathological assessment confirmed frank focal cortical dysplasia type IIa in the MEG-defined SOZ, which was based on source imaging of averaged ictal spikes at seizure onset. We investigated temporal changes together with spatial differences in spectral parameters of background brain activity, namely the aperiodic broadband offset and slope, and assessed how they confounded the interpretation of apparent variations of signal power in typical electrophysiological bands. Our data show that the SOZ was associated with a higher aperiodic offset and exponent during the seizure compared to control regions. Both parameters increased in all regions from 2 min before the seizure onwards. Regions anatomically closer to the SOZ also expressed higher values compared to contralateral regions, potentially indicating ictal spread. We also show that narrow-band power changes were caused by these fluctuations in the aperiodic component of ongoing brain activity. Our results indicate that the broadband aperiodic component of ongoing brain activity cannot be reduced to background noise of no physiological interest, and rather may be indicative of the neuropathophysiology of the SOZ. We believe these findings will inspire future studies of ictal MEG cases and confirm their significance. (shrink)

In french and english speaking countries, the articulation between epistemological beliefs, conceptions of teaching and learning and pedagogical practices of secondary school teachers in the natural sciences and humanities has been little studied (Araújo-Oliveira, 2012 ; Bartos et Lederman, 2014 ; Wanlin et al., 2019). Yet, while teachers display predominantly constructivist beliefs about teaching and learning, their teaching practices remain rather passive (OECD, 2019). Like in Therriault et al. (2018-2023), this article explores the characteristics of epistemological beliefs, conceptions of teaching (...) and learning, and teaching practices among a population of 112 secondary school teachers (beginners, intermediate and experienced) in the humanities and natural sciences in French-speaking Belgium. In a second step, we explore the articulations between these three theoretical constructs either from statistical analyses or from a more interpretative perspective. Quantitative analysis of the data (PCA, factorial ANOVA, correlations and Chi-square) show that teachers’ epistemological beliefs are rather refined, that there is an effect of professional seniority on these beliefs and that there is a link between refined epistemological beliefs and traditional conceptions of teaching and learning. Finally, teachers’ self-reported practices appear to be insensitive to the discipline being taught. (shrink)

The articulation between epistemological beliefs, conceptions of teaching and learning, and teaching practices of secondary school science and humanities teachers has been little studied, particularly in the francophone world (Araújo-Oliveira, 2012, 2019 ; Bartos & Lederman, 2 014 ; Wanlin et al., 2019). Yet, while teachers display predominantly constructivist beliefs about teaching and learning, their actual teaching practices remain rather passive (TALIS international survey - OECD, 2019). After characterizing these three theoretical constructs in a sample of 215 Quebec secondary school (...) teachers (beginners, intermediate and experienced) in the humanities and social sciences and natural sciences, the article explores their articulations either through statistical analysis or by putting them into perspective in an interpretative phase of the research. The results are based on the quantitative analysis of teachers’ responses to a three-part closed online questionnaire. Statistical analyses (PCA, factorial ANOVA, correlations and Chi-square tests) show that teachers’ epistemological beliefs are rather refined, that there is an effect of seniority in the profession and an effect of the discipline taught on these beliefs, as well as a link between refined epistemological beliefs and traditional conceptions of teaching and learning. Finally, teachers’ self-reported practices appear to be insensitive to the discipline being taught. (shrink)

Tous ceux qui s’intéressent à la vie et à l’œuvre de Descartes connaissent l’épisode rapporté par Adrien Baillet dans sa Vie de monsieur Descartes et évoqué par Descartes lui-même dans une lettre à son ami Villebressieu en 1631 : vers la fin des années 1620, le jeune Descartes participa à Paris chez le nonce apostolique, le cardinal Guidi di Bagno, à une « assemblée de personnes savantes et curieuses », parmi lesquelles le cardinal de Berulle et Mersenne. L’orateur était..

This book provides a comprehensive commentary of the Philebus designed to shed light on the nature and function of the good in Plato’s philosophy as a whole. Topics discussed include dialectic, pleasure, epistemology, and the relations between metaphysics and ethics.

In this collection of essays, Bromberger explores the centrality of questions and predicaments they create in scientific research. He discusses the nature of explanation, theory, and the foundations of linguistics.

This opinion paper takes aim at an error made recently by Clarivate Analytics in which it sent out an email that congratulated academics for becoming exclusive members of academia’s most cited elite, the Highly Cited Researchers. However, that email was sent out to an undisclosed number of non-HCRs, who were offered an apology shortly after, through a bulk mail, which tried to down-play the importance of the error, all the while praising the true HCRs. When Clarivate Analytics senior management was (...) contacted, the company declined to offer an indication of the number of academics who had been contacted and erroneously awarded the HCR status. We believe that this regrettable blunder, together with the opacity offered by the company, fortify the corporate attitude about the value of the journal impact factor, and what it represents, namely a marketing tool that is falsely used to equate citations with quality, worth, or influence. The continued commercialization of metrics such as the JIF is at the heart of their use to assess the “quality” of a researcher, their work, or a journal, and contributes to a great extent to driving scientific activities towards a futile endeavor.

Neuroconstructivism: How the Brain Constructs Cognition proposes a unifying framework for the study of cognitive development that brings together (1) constructivism (which views development as the progressive elaboration of increasingly complex structures), (2) cognitive neuroscience (which aims to understand the neural mechanisms underlying behavior), and (3) computational modeling (which proposes formal and explicit specifications of information processing). The guiding principle of our approach is context dependence, within and (in contrast to Marr [1982]) between levels of organization. We propose that three (...) mechanisms guide the emergence of representations: competition, cooperation, and chronotopy; which themselves allow for two central processes: proactivity and progressive specialization. We suggest that the main outcome of development is partial representations, distributed across distinct functional circuits. This framework is derived by examining development at the level of single neurons, brain systems, and whole organisms. We use the terms encellment, embrainment, and embodiment to describe the higher-level contextual influences that act at each of these levels of organization. To illustrate these mechanisms in operation we provide case studies in early visual perception, infant habituation, phonological development, and object representations in infancy. Three further case studies are concerned with interactions between levels of explanation: social development, atypical development and within that, developmental dyslexia. We conclude that cognitive development arises from a dynamic, contextual change in embodied neural structures leading to partial representations across multiple brain regions and timescales, in response to proactively specified physical and social environment.

Over the last 40 years or so, there has been an explosion of cultural evolution research in anthropology and archaeology. In each discipline, cultural evolutionists investigate how interactions between individuals translate into group level patterns, with the aim of explaining the diachronic dynamics and diversity of cultural traits. However, while much attention has been given to deterministic processes, we contend that current evolutionary accounts of cultural change are limited because they do not adopt a systematic stochastic approach. First, we show (...) that, in contrast with the intense debates in ecology and population genetics, the importance of stochasticity in evolutionary processes has generated little discussion in the sciences of cultural evolution to date. Second, we speculate on the reasons, both ideological and methodological, why that should be so. Third, we highlight the inadequacy of genetically-inspired stochastic models in the context of cultural evolution modelling, and ask which fundamental stochastic processes might be more relevant to take up. We conclude that the field of cultural evolution would benefit from a stochastic revolution. For that to occur, stochastic models ought to be developed specifically for cultural data and not through a copy-pasting of neutral models from population genetics or ecology. (shrink)

This research investigates the potential for a “fair” co-branding operation. A major corporate brand is fictitiously allied with a Fair Trade labelling organization brand. The sample for the study is composed of 540 respondents, representative of the French population. By considering commercial brands and Fair Trade labels as dissimilar in terms of customers’ perceived Fair Trade orientations, this article studies how this lack of similarity impacts perceived congruence between both entities and how prior brand attitudes and congruence influence customers’ evaluation (...) of the co-branded product. The results of this research demonstrate that: Consumer prior brand attitudes toward the partner brands influence very little customers’ evaluation. Perceived similarity of the partner brands has a strong influence toward congruence of the co-branding operation. Results also indicate that congruence has a strong influence upon customers’ evaluation. An inverted U-shaped relationship exists between perceived similarity and relevancy of the alliance, and between expectancy and customers’ evaluation. The results obtained through the test of a partial least square model, and inverted U-shaped hypothesis, represent a new insight into co-branding theory. The high discursive power of fair co-branding is a key issue: the corporate brand provides the alliance with its leading position, while the Fair Trade brand provides the ethical attribute. (shrink)

This paper studies ‘minority’ initiatives to organize sports games. A meta-analysis of published data in the literature identifies the formal appearance taken by each of these initiatives under the Olympic model. But it also conduces to build a number of indicators to answer a series of questions about their logic and strategies. All the initiatives studied are based on an ambivalent posture that, while based on the denunciation of a discriminating space, claim access to it. By an astonishing paradox, ‘non-normative’ (...) actors are driven to reclaim a model that, under cover of Universal, aims to establish a norm that is situated and dated. In practice, they use two types of strategies: a strategy for participation in the Olympics to transform them into a space which represents a fight against exclusion, or a strategy to create alternative events. Whatever the strategy, these initiatives are implemented according to their objectives. Differentiated in their forms—participatory or autonomy—they are also in their purpose. The comparison of these initiatives shows that ultimately, beyond strategies and logic inherent in different social, historical and organizational contexts, the mobilizations of the actors reveal the same ambivalence about the sports model conveyed by the Olympic institution.

We introduce three natural collective variants of the well-known axiom of desirability, which require that if the contributions of a first coalition are at least as large as the contributions of a second coalition, then the payoff in the first coalition should be as large as the payoff in the second coalition. These axioms are called coalitional desirability and average coalitional desirability. The third variant, called uniform coalitional desirability, applies only to coalitions with the same size. We show that coalitional (...) desirability is very strong: no value satisfies simultaneously this axiom and efficiency. To the contrary, the combination of either average coalitional desirability or uniform coalitional desirability with efficiency and additivity characterizes the equal division value. (shrink)

This paper examines the discussion about false pleasures in the "Philebus" (36 c3-44 a11). After stressing the crucial importance of this discussion in the economy of the dialogue, it attempts to identify the problematic locus of the possibility of true or false pleasures. Socrates points to it by means of an analogy between pleasure and doxa. Against traditional interpretations, which reduce the distinction drawn in this passage to a distinction between doxa and pleasure on the one hand and their object (...) on the other, it is argued that, rather, Socrates distinguishes between the mere fact of having a doxa or a pleasure, on the one hand, and the content of these acts, on the other hand. Consequently, the possibility for a pleasure to be false does not concern its relation to an object, but the affective content which defines it. In order to show how the affective content of a pleasure can be false, it is necessary to examine the three species of false pleasures described by Socrates in their relation to appearance and imagination. Appearance is not identical with perception for Plato: it consists in a mixture of perception and doxa. As for imagination, it consists in "illustrating" a doxa present in the soul by means of a "quasi-perception". It is the presence of a doxa in each of these processes which makes it possible for them to be true or false, while mere perception cannot be either true or false. It is then argued that according to the "Philebus" pleasure can be false precisely because its affective content is not a mere perception, but either an appearance or an imagination. (shrink)

We provide characterizations of the equal division values and their convex mixtures, using a new axiom on a fixed player set based on player nullification which requires that if a player becomes null, then any two other players are equally affected. Two economic applications are also introduced concerning bargaining under risk and common-pool resource appropriation.

The Analytic/Synthetic distinction did not originate in Kant, but in Port-Royal's logical theory. The key for the doctrine is the explicite recognition of two different kinds of relative clauses, e.g. explicative and determinative. In the middle eighteenth century the distinction becomes a topic within the grammars. Although we can find by grammarians different criteria for the distinction, these criteria (for which we can find medieval sources) are for the main predictable from the original theory of ideas, which was presented in (...) Port-Royal's logical writings. The topic of the two relative clauses (somewhat broader than the analytic/synthetic distinction) can be used to give empirical criteria for analyticity and also for revisiting Quine's criticism of the topic. Analyticity yet appears as a master piece of classical linguistic philosophy and not as being the empty dogma of modern empiricism. (shrink)

Cet article analyse les emplois schelérien et heideggérien de l’expression « logique du coeur ». Il revient sur l’origine de cette expression – forgée par Scheler, qui l’attribue à tort à Pascal en soulignant son opposition à la raison cartésienne – avant de reconstruire l’usage qu’en fait Heidegger. Trois phases sont mises au jour : Heidegger fait l’économie de cette expression dans ses jeunes années afin de prendre ses distances avec la doctrine schelérienne et pascalienne des sentiments ; il y (...) recourt dans les années trente et quarante pour signaler que cette doctrine est déterminée par la « logique » métaphysique cartésienne, qu’il oppose à deux logiques du coeur non métaphysiques (celles du λόγος grec héraclitéen et parménidien et du Λόγος johannique) ; dans les années cinquante, Heidegger abandonne pourtant cette expression au motif que toute logique – moderne (cartésienne) comme grecque et biblique – demeure métaphysique.

Although Pascal is a thinker of the figure of Christ, he seems to neglect the other Persons of the Trinity, in particular the Holy Spirit. This article examines the place Pascal gives to the third Person of the Trinity. It shows that, for Pascal, the Holy Spirit plays an important role in the conversion of man, insofar as he spreads in his heart the grace of Christ sent by the Father. Finally, this study comes to a difficult fragment of Pascal’s (...) in which he asks whether all Holy Scripture is dictated by the Holy Spirit, in order to propose a new reading. (shrink)

The Newell Test is an ambitious and promising project, but not without pitfalls. Some of the current criteria are not theoretically neutral, whereas others are unhelpful. To improve the test, the learning and development criteria are reviewed and revised, which suggests adding a maturation criterion as well. Such changes should make the Newell Test more general and useful.

El artículo estudia el fragmento de una carta de Prisciliano recogida en el "Commonitorium de errore priscillianistarum et origenistarum" de Pablo Orosio, para recolocar el fragmento en el contexto orosiano. Posteriormente se estudia el fragmento en el contexto de las fuentes priscilianas, para ver si se puede hacer un acercamiento con las ideas de los "Tratados de Wurzburg", y las de E.-Ch.Babut y E. Spät principalmente.

Si le xixe siècle fut le temps de l’émergence de la figure de la “ grande voyageuse ”, on ne saurait surestimer cette innovation. La hiérarchie des genres de récits de voyage, l’importance du contre-exemple britannique, la condamnation morale de la voyageuse solitaire manifestent assez le sentiment de l’illégitimité du voyage féminin. Pourtant, pèlerines, valétudinaires et touristes se multiplièrent dans un siècle qui fut aussi celui de l’invention du voyage de noces. Cet article tente de prendre la mesure de l’ensemble (...) des normes qui ont alors commandé les pratiques, nombreuses et variées, du voyage féminin. (shrink)

Increasingly, frontiers between business and philanthropy seem to be blurred. Reward-Based Crowdfunding platforms contribute to this blurring of lines since they propose funders to support both for-profit and philanthropic projects. Our empirical paper explores the case of Ulule, the leading crowdfunding platform in Europe. Our results, based on a statistical analysis of more than 3000 projects, show that crowdfunding platforms foster specific kinds of relationships relying on reciprocal giving, beyond the usual opposition between altruistic and selfish motivations. We use the (...) work of Marcel Mauss to account for this process of reciprocal giving, and we argue that Maussian theory of gift can be used more generally to describe funding activities in the context of early stage entrepreneurship.

Outline of the historiographic discussion on 18th-century linguistic theories.

La connaissance est traditionnellement envisagée comme un processus mettant en rapport un sujet et un objet. Le processus peut être doublement orienté selon que l'on considère la réception de l'information par l e sujet, ou la représentation de l'objet qui peut avoir différentes modalités, parmi lesquelles je compte l'assertion de quelque chose quant à l'objet. Je schématise ces deux orientations de la façon suivante: I = K1 R = K2Prendre connaissance d'un manuel de mathématiques, être ébloui par une lumière vive, (...) n'est pas identique à résoudre un problème de mathématiques, ou à savoir que la voiture qui vient en face n'a pas mis ses feux de croisement. Il y a bien lieu de distinguer deux types de connaissances: K1 et K2; je ne me préoccuperai pas de la question générale de l'identité des éléments de chacune et j'utiliserai les mêmes symboles S et O.

"La grande question métaphysique aujourd'hui, en matière de langage, est de savoir si un modèle computationnel suffit à expliquer le comportement linguistique humain. Est-ce que la faculté de langage de chacun d'entre nous et plus spécialement sa compétence linguistique, s'explique parce que nous avons des algorythmes implémentés dans notre tête? Cette question appartient de plein droit à la philosophie de la linguistique. Elle a une vaste portée. En aval, elle concerne la représentation d'une bonne partie du comportement humain, selon le (...) modèle qu'en donnent les cognitivistes de stricte obédience. En amont, elle concerne tout simplement le vieux débat de théorie de la connaissance entre le rationalisme et l'empirisme. L'objet de ce livre est une critique fouillée du rationalisme dans ses fondements linguistiques. Il prend donc la forme d'une analyse de la nature du savoir linguistique et de celle du langage.... Il s'agit de constituer les bases d'une nouvelle version de l'empirisme que nous pouvons baptiser externalisme. Les résultats développés dans ce livre concernent principalement la théorie de la science et celle du langage. La thèse ultime de l'externalisme c'est que l'esprit lui-même est d'essence historique et empirique." Extrait de l'introduction. (shrink)
