In this paper, chaotic dynamics of a mixed Rayleigh–Liénard oscillator driven by parametric periodic damping and external excitations is investigated analytically and numerically. The equilibrium points and their stability evolutions are analytically analyzed, and the transitions of dynamical behaviors are explored in detail. Furthermore, from the Melnikov method, the analytical criterion for the appearance of the homoclinic chaos is derived. Analytical prediction is tested against numerical simulations based on the basin of attraction of initial conditions. As a result, it is (...) found that for ω = ν, the chaotic region decreases and disappears when the amplitude of the parametric periodic damping excitation increases. Moreover, increasing of F 1 and F 0 provokes an erosion of the basin of attraction and a modification of the geometrical shape of the chaotic attractors. For ω ≠ ν and η = 0.8, the fractality of the basin of attraction increases as the amplitude of the external periodic excitation and constant term increase. Bifurcation structures of our system are performed through the fourth-order Runge–Kutta ode 45 algorithm. It is found that the system displays a remarkable route to chaos. It is also found that the system exhibits monostable and bistable oscillations as well as the phenomenon of coexistence of attractors. (shrink)

Letter-position tolerance varies across languages. This observation suggests that the neural code for letter strings may also be subtly different. Although language-specific models remain useful, we should endeavor to develop a universal model of reading acquisition which incorporates crucial neurobiological constraints. Such a model, through a progressive internalization of phonological and lexical regularities, could perhaps converge onto the language-specific properties outlined by Frost.

Cognitive forms vary considerably as a human being detaches herself from what is closest and most personal and moves to communicate — in the broad sense of taking part in a common matter — across increasing relational distances. The article proposes to deal with the variety of cognitive formats which cannot `commonize' cognition to an equal degree, relating them to a set of regimes of engagement with the world that are identified in terms of the dependency between the human agent (...) and her environment. The good that engagement aims to guarantee orients how reality is grasped and specifies the format of what constitutes relevant information. This analysis offers new insight into the composition of communities as well as persons who have to cope with the plurality of cognitive formats and engagements from the very familiar to the most public.

La famille Poincaré trouve ses racines en Lorraine, dans les départements de Meurthe-et-Moselle, de la Meuse et des Vosges. Arrancy-sur-Crusne, Bar-le-Duc, Landaville, Longuyon, Lunéville, Nancy, Neufchâteau, Remenoncourt, Xirocourt sont quelques-unes des communes ayant vu naître des ancêtres des deux Poincaré les plus connus, Henri et Raymond. Cet article propose une histoire de la famille d’Henri Poincaré sur le temps long et prend appui sur une vaste synthèse des informations généalogiques existantes. Dans un premier temps j’explore rapidement les origines anciennes du (...) nom « Poincaré » et certaines branches indirectes de la famille ; j’analyse ensuite de manière plus fine les parcours des acteurs principaux de la branche directe, en particulier ceux du père, de l’oncle et du grand-père paternels d’Henri Poincaré. Je termine ce parcours en me focalisant rapidement sur les mariages et les descendants respectifs d’Henri Poincaré et de sa sœur Aline. Un tel essai est structuré autour d’une double ambition : d’une part, apporter une contribution à la biographie de Poincaré centrée sur la sphère privée ; d’autre part, caractériser finement le milieu social dans lequel Poincaré a pu évoluer au cours de sa vie.

The view of Deitz and Arrington (1984) that Wittgenstein's ordinary language philosophy allows behaviorism to use cognitive terms with a behavioristic system is disputed and an alternative is suggested.

Au-delà des frontières des langues, des cultures juridiques et systèmes de droit, conciliant synchronie et diachronie, le Professeur Mattila nous offre une oeuvre riche en couleurs, rencontres illustres et cas d’espèce. Nul doute qu’il s’agit là d’un ouvrage de référence, à la fois au regard de l’introduction d’une approche heuristique et de la cartographie d’un champ de connaissances commun au juriste et au linguiste. Sa vaste étude des interactions terminologiques et conceptuelles des langues et traditions juridiques européennes propose un tableau (...) minutieux, systématique et argumenté de la situation du langage juridique dans cinq langues. Elle offre une réflexion sur le développement de ces langues, notamment sur le plan international. Travail herculéen s’il en est, il ne pouvait être réalisé que par un humaniste accompli. Heikki Mattila, professeur émérite de jurilinguistique à l’Université de Lapland en Finlande, est juriste, spécialiste multilingue du langage juridique, linguiste .. (shrink)

Résumé Où va la peinture est un livre de Laurent Marissal qui se présente à la fois comme un traité sur la peinture et comme une œuvre peinte. Les actions qu’il relate sont elles-mêmes revendiquées comme des actions picturales. L’article s’interroge sur ces usages hétérodoxes de la notion de « picturalité », tout d’abord au niveau de la mise en forme narrative du livre, puis à celui des actions que cette forme a pour dessein de relater. Une dernière partie (...) étudie la relation du travail de Laurent Marissal avec le courant du narrative art. (shrink)

This is the first volume of a two-volume project whose aim is to publish all the known Middle English manuscript translations of the French Somme le mi, a thirteenth-century manual of religious instruction offering teaching on the Decalogue, the seven deadly sins and their remedies, compiled by the Dominican friar Laurent of Orleans. The project extends and deepens our knowledge of the influence of this popular French text, known today only from the versions entitled The Ayen bite of Inwit (...) and The Book of Vices and Virtues, published in 1866 and 1942, respectively. This volume presents the versions extant in BL MSS Royal 18. A. x and Add. 37677; the second will cover the versions in Cambridge, Corpus Christi College, MS 494, Oxford, Bodleian Library, MS Ashmole 1286, and Oxford, Bodleian Library, MS e Musaeo 23. The texts of both volumes have been prepared with the help of the recently-published edition of the French text, a circumstance from which the earlier English editions were unable to benefit. It is likely that the versions edited here for the first time will make a considerable contribution to our understanding of the processes of textual transmission and to that of translation itself in English literary circles of the fifteenth century.

It is only approximately one year before Sein und Zeit was published that Heidegger read Kant for the first time with attention and interest. Has this late reading had an influence on the treatise that Heidegger was writing? The thesis that we stand for is that Kant’s main influence shall be found in no passage of the treatise in particular, but mostly in the decision of adopting the form of a treatise.

This article argues that many situations in social life can be analyzed by their requirement for the justification of action. It is in particular in situations of dispute that a need arises to explicate the grounds on which responsibility for errors is distributed and on which new agreement can be reached. Since a plurality of mutually incompatible modes of justification exists, disputes can be understood as disagreements either about whether the accepted rule of justification has not been violated or about (...) which mode of justification to apply at all. The article develops a grammar of such modes of justification, called orders of worth (grandeur), and argues that the human capacity for criticism becomes visible in the daily occurrence of disputes over criteria for justification. At the same time, it is underlined that not all social situations can be interpreted with the help of such a sense of justice, which resides on a notion of equivalence. Regimes of love, of violence or of familiarity are systematically distinct from regimes of justification. (shrink)

Malgré l’évidente réticence du parti anticlérical à adopter une nouvelle religion avec un dogme et des sacrements, la promotion philosophico-politique du lien social sous la Troisième République a conduit à revisiter en théorie, sinon en pratique, quelques thèmes majeurs du positivisme religieux. Le parcours ici proposé va de la politique (Ferry, Léon Bourgeois, Jaurès, la libre-pensée) à la philosophie morale et sociale (Jean-Marie Guyau, Alfred Fouillée, Gustave Belot, Émile Boutroux) et de celle-ci à la sociologie (Durkheim) et à l’analyse de (...) la pensée (Alain). L’usage ambigu, sélectif, des textes et des idées de Comte, mélange d’hommage et d’aversion, reflète la liberté d’interprétation qui parvient à féconder une philosophie au-delà de son cadre d’origine. L’enquête privilégie cet axe de recherche et met au jour les transactions par lesquelles s’est monnayé un héritage que l’on aurait tort de croire aujourd’hui disparu. (shrink)

According to Thomas Reid, powers of will and powers of understanding are distinguishable in thought, but conjoined in practice. This paper examines the claim that there is no inert intelligence, the operations of the understanding involving some degree of activity. The question is: whose activity? For it is clear that a great deal of our mental activity is not in our power. We need to distinguish between a weak and a strong sense of ‘power’, and consider our dependence ‘upon God (...) and the laws of nature’ in our mental exertions. (shrink)

The present study is an attempt to relate the multicomponent response of the cytoskeleton (CSK), evaluated in twisted living adherent cells, to the heterogeneity of the cytoskeletal structure - evaluated both experimentally by means of 3D reconstructions, and theoretically considering the predictions given by two tensegrity models composed of (four and six) compressive elements and (respectively 12 and 24) tensile elements. Using magnetic twisting cytometry in which beads are attached to integrin receptors linked to the actin CSK of living adherent (...) epithelial cells, we specifically measured the elastic CSK response at quasi equilibrium state and partitioned this response in terms of cortical and cytosolic contributions with a two-component model (i.e., a series of two Voigt bodies). These two CSK components were found to be prestressed and exhibited a stress-hardening response which both characterize tensegrity behaviour with however significant differences: compared to the cytosolic component, the cortical cytoskeleton appears to be a faster responding component, being a less prestressed and easily deformable structure. The discrepancies in elastic behaviour between the cortical and cytosolic CSK components may be understood on the basis of prestress tensegrity model predictions, given that the length and number of constitutive actin elements are taken into account.

That Jean Gayon never paid attention to Darwin’sDarwin, CharlespangenesisPangenesis might seem like an oddity given that natural selectionSelection and biological heredity were his primary focuses for decades. This lack of interest reveals Gayon’s specific methodological orientation: he aimed at producing rational reconstructionsRational reconstruction of the way a scientific hypothesisHypothesis entered experimentation and subsequently evolved within a specific theoretical pattern. Gayon’s most important achievements, Darwinism’sDarwinismStruggle for Survival (1998) in the first place, were all based on this “structuralist approachStructuralist approach (to history (...) of science)”, where philosophy of science provides a strong problematization and even shapes the historical narrative.

Derrida's treatment of Chinese script as essentially non-phonetic in Of Grammatology has been a recurrent leitmotif among several sinologists and scholars of Chinese origin, particularly in Rey Chow's famous 2001 essay ‘How Inscrutable Chinese Led to Globalized Theory’. Despite forceful refutations of this misconception, the accusation of a fantasizing ‘ethnocentrism thinking itself as anti-ethnocentrism’ has endured and could still be found in a recent 2015 article suggestively titled ‘A Sort of European Hallucination: On Derrida's “Chinese Prejudice”’. This essay will probe (...) into the recurrent accusation of a Derridean hallucination of the other as the other's own hallucination in order to analyse the sustained misreading of Derrida's phrase ‘outside of all logocentrism’ used about the Chinese ideogram.

A semimeasure is a generalization of a probability measure obtained by relaxing the additivity requirement to superadditivity. We introduce and study several randomness notions for left-c.e. semimeasures, a natural class of effectively approximable semimeasures induced by Turing functionals. Among the randomness notions we consider, the generalization of weak 2-randomness to left-c.e. semimeasures is the most compelling, as it best reflects Martin-Löf randomness with respect to a computable measure. Additionally, we analyze a question of Shen, a positive answer to which would (...) also have yielded a reasonable randomness notion for left-c.e. semimeasures. Unfortunately, though, we find a negative answer, except for some special cases. (shrink)
