It is often acknowledged that mindfulness facilitates emotion regulation on a long-term scale. Only few empirical studies support the hypothesis that even a brief mindfulness induction among subjects without previous experience of meditation allows an effective reduction of both positive and negative emotions. To the best of our knowledge, this hypothesis has never been tested when comparing mindfulness to other regulation strategies known to be effective. The current study investigates the effects of mindfulness, reappraisal and expressive suppression during the regulation (...) of positive emotions. Forty-five participants without previous meditation experience watched four positive video clips while applying a specific regulation strategy: mindful attention, reappraisal, expressive suppression or no strategy. Video clips were matched for intensity and positive emotions index. Each of them was evaluated on two dimensions, valence and arousal. Moreover, participants’ facial expressions were recorded during the presentation of the video clips. Results showed that participants report less positive affect in reappraisal and mindful attention conditions compared to expression suppression and a control condition; and the facialexpression – activation of AU12 and AU6 – varies with the regulation strategy applied. Results demonstrate the effectiveness of mindfulness in decreasing both the evaluative judgment of positive video clips and the related facial expression, among participants without previous mindfulness experience.

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 presents a version of hylomorphism that intends to solve problems faced by contemporary hylomorphism. After showing that attempts to understand form as sets or relation of essential properties fail at taking into account the dynamic development of substances, the paper suggests another version of hylomorphism able to solve these difficulties. A functionalist version of hylomorphism is then defended: the best way to understand how form can be present throughout all the developmental stages of a substance is to understand (...) it as a certain kind of function.

Misunderstanding of the dynamical behavior of the ventilatory system, especially under assisted ventilation, may explain the problems encountered in ventilatory support monitoring. Proportional assist ventilation (PAV) that theoretically gives a breath by breath assistance presents instability with high levels of assistance. We have constructed a mathematical model of interactions between three objects: the central respiratory pattern generator modelled by a modified Van der Pol oscillator, the mechanical respiratory system which is the passive part of the system and a controlled ventilator (...) that follows its own law. The dynamical study of our model shows the existence of two crucial behaviors, i.e. oscillations and damping, depending on only two parameters, namely the time constant of the mechanical respiratory system and a cumulative interaction index. The same result is observed in simulations of spontaneous breathing as well as of PAV. In this last case, increasing assistance leads first to an increase of the tidal volume (VT), a further increase in assistance inducing a decrease in VT, ending in damping of the whole system to an attractive fixed point. We conclude that instabilities observed in PAV may be explained by the different possible dynamical behaviors of the system rather than changes in mechanical characteristics of the respiratory system.

Durant la fin des années 1940, les sections de sport et le comité national olympique soviétique intègrent les fédérations et le Comité international olympique, ce qui leur permet de prendre part aux compétitions et à la communauté mondiale des sportifs. Très vite, les championnes d’URSS remportent de francs succès. La participation soviétique y a une double fonction dans la « politique extérieure de l’image » (R. Frank). D’une part, elle donne à voir les succès en matière d’égalité femmes-hommes. D’autre part, (...) elle permet d’obtenir des médailles, essentielles à la mesure de la suprématie soviétique en matière de sport. Cet article étudie la manière dont l’administration et les médias soviétiques ont construit – en pratique et en représentations – la supériorité sportive féminine soviétique en interaction avec l’étranger. Loin d’être isolés, les acteurs du sport soviétique s’adaptent aux règlements internationaux, aux réactions que les performances des athlètes d’URSS suscitent et aux controverses qui surgissent dans la presse de l’adversaire.

Peter John Olivi’s relationship to Bonaventure is intriguing.1 Outwardly, they both appear as the leading figures of two different trends of Franciscan politics: Olivi usually being qualified as a “radical” inspiring the dissidence of the Spirituals, while Bonaventure would represent a central and balanced attitude regarding Franciscan poverty. Likewise, as far as their apocalyptical expectations are concerned, Olivi is certainly an overt and avowed Joachite, whereas Bonaventure supposedly makes a more detached use of Joachim of Fiore’s works. Recent studies of (...) Olivi’s philosophical approaches present him as anticipating themes soon to be developed by Duns Scotus rather than associate him with the Bonaventurian... (shrink)

CorpusReader permet à la fois de construire cette annotation contextualisante puis d'en extraire des sous-ensembles et des quantifications pour des (...) analyses quantitatives. (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.

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.

In this paper, I examine Plato’s and Aristotle’s contrasted treatment of the “Good itself ” and its relation to the human good. Contrary to a common view, Aristotle does not attack the very concept of a Good itself, but rather Plato’s interpretation of it as the Idea of the Good. One of his central criticisms is that such an Idea would have no practical use. By an analysis of the Philebus, I try to show why and how this Idea does (...) have such a use in Plato, but in a way which could not satisfy his pupil, because for Aristotle, the Good itself must be an ultimate end which must have a direct efficiency on the whole world, without any need of the mediation of knowledge. In the Metaphysics, Aristotle shows that such an end can be identified with a purely active intelligence, which he names God. Although this Good itself is absolutely necessary and thus cannot be a “practical good” in Aristotle’s terms, its contemplation by human intelligence can be, because it is for its part contingent. I conclude in assessing the main consequences of Plato’s and Aristotle’s different views of the Good itself on their philosophy as a whole. (shrink)

In this paper we show that the membership problem for second order non-linear Abstract Categorial Grammars is decidable. A consequence of that result is that Montague-like semantics yield to a decidable text generation problem. Furthermore the proof we propose is based on a new tool, Higher Order Intersection Signatures, which grasps statically dynamic properties of λ-terms and presents an interest in its own.

Intuitive predictions and judgements under uncertainty are often mediated by judgemental heuristics that sometimes lead to biases. Our micro-developmental study suggests that a presumption of rationality is justified for adult subjects, in so far as their systematic judgemental biases appear to be due to a specific executive-inhibition failure in working memory, and not necessarily to a lack of understanding of the fundamental principles of probability. This hypothesis was tested using an experimental procedure in which 60 adult subjects were trained to (...) inhibit the classical conjunction bias on a frequency judgement task derived from Tversky and Kahneman's work. Pre- and post-test performance was assessed via a probability judgement task. The data indicated a training effect, suggesting that subjects traditionally labelled as "irrational" with respect to the classical rules of inductive reasoning are in fact "inefficient inhibitors". These findings are discussed in terms of a polymorphous view of rationality. (shrink)

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 paper analyzes Paul of Venice’s theory of measurement of natural properties and changes. The main sections of the paper correspond to Paul’s analysis of the three types of accidental changes, for which the Augustinian philosopher sought to provide rules of measurement. It appears that Paul achieved an original synthesis borrowing from both Parisian and Oxfordian sources. It is also argued that, on top of this theoretical synthesis, Paul managed to elaborate a quite original theory of intensive properties that marks (...) him out not only from the nominalist framework of his Parisian sources but also from the usual realist treatments of the problem. Finally, it is shown that, to a certain extent, Paul undertook to apply the mathematical and logical tools inherited from the Calculatores tradition to empirical problems of natural philosophy, leading to reevaluate his role in the evolution of scientific thought in early 15th-century Italy.

A new class of values combining marginalistic and egalitarian principles is introduced for cooperative TU-games. It includes some modes of solidarity among the players by taking the collective contribution of some coalitions to the grand coalition into account. Relationships with other class of values such as the Egalitarian Shapley values and the Procedural values are discussed. We propose a strategic implementation of our class of values in subgame perfect Nash equilibrium. Two axiomatic characterizations are provided: one of the whole class (...) of values, and one of each of its extreme points. (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.

La philosophie française actuelle se réduit souvent à de l’historiographie ou à de l’exégèse de textes, s’exposant ainsi au reproche de stérilité. Certes, la philosophie ne doit pas céder à une telle tendance sous peine de se discréditer ou de disparaître. Cependant, à l’inverse, l’histoire de la théorie et l’exégèse sont nécessaires à la théorie non seulement pour produire de nouvelles hypothèses mais aussi pour les justifier, ceci étant vrai pour toutes les disciplines scientifiques.

The doctrine of the “just price” is more than often described as the core of the “economic” thinking of the Scholastics (de Roover 1958; Baldwin 1959; Wilson 1975; Worland 1977). In fact, one could hardly contest that the notion occupies a place of high importance in the economic reflections of the Medieval Doctors. It is of no doubt that their study of economic reality led them to call up very frequently the said notion of “just price”. Yet the insistence with (...) which modern historiography has itself treated this – central but particular – element of the Scholastic economic thinking conceals, to our opinion, some of its important sights and interests. An “objective” approach of the scholastic theory seems to command such an interpretation. But why is the phrase “just price” so often used and developed by the Doctors? Such a simple question cannot be answered simply by focusing on the notion. From a more “methodological” point of view, just price appears only like the final result of a complex argumentation. Little attention has been given to the fact that (1) the issue at stake is less a problem of correctness in limited bargaining than a general question of social justice; (2) the method used to deal with this vast subject in the field of economic relations is a systematic “contractual” analysis. The second point forms the main theme of this paper. (shrink)

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)

On n'a jamais bien jugé l'empirisme, supposant d'emblée qu'il était l'opposé du rationalisme. En fait, qu'il s'agisse de l'empirisme ou du rationalisme, on déploie dans chaque cas une chaîne de séquences dont il s'agit de rendre les termes solidaires: rationalisme ═ a priorisme ═ principes généraux abstraits ═ raison universelle ═ idéalisme ═ la vérité est raison pure empirisme ═ a postériorisme ═ pas de principes généraux abstraits ═ pas d'ordre rationnel ═ positivisme ═ réalisme.

New and recent axioms for cooperative games with transferable utilities are introduced. The non-negative player axiom requires to assign a non-negative payoff to a player that belongs to coalitions with non-negative worth only. The axiom of addition invariance on bi-partitions requires that the payoff vector recommended by a value should not be affected by an identical change in worth of both a coalition and the complementary coalition. The nullified solidarity axiom requires that if a player who becomes null weakly loses (...) from such a change, then every other player should weakly lose too. We study the consequence of imposing some of these axioms in addition to some classical axioms. It turns out that the resulting values or set of values have all in common to split efficiently the worth achieved by the grand coalition according to an exogenously given weight vector. As a result, we also obtain new characterizations of the equal division value. (shrink)

Using the matching bias example, the aim of the present studies was to show that adults' reasoning biases are due to faulty executive inhibition programming. In the first study, the subjects were trained on Wason's classical card selection task; half were given training in how to inhibit the perceptual matching bias (experimental group) and half in logic without the inhibition component (control group). On the pre- and post-tests, their performance was assessed on the Evans conditional rule falsification task (with a (...) negation in the antecedent of the rule), a task that also involves matching bias. In addition, subjects were tested for perceptual field dependence/independence using the Embedded Figures Test. The results brought out a specific inhibition training effect, as well as a clear-cut relationship in the experimental group between receptiveness to training and perceptual field independence. In the second study, the training paradigm was the same except that on the pre- and post-tests, the negation was in the consequent of the conditional rule (in this case, the perceptual matching response corresponds to the logical response). The subjects succeeded on the pre-test, and the matching-bias inhibition training had a negative effect on post-test performance. This specific negative priming effect confirms the inhibitory impact of our experimental training and outlines the dissociation of inhibition and logical components. (shrink)

This paper investigates the late medieval controversy over the causal role of substantial forms in the generation of new substances. At the beginning of the fourteenth century, when there were two basic positions in this debate (section II), an original position was defended by Walter Burley and Peter Auriol, according to which accidents alone—by their own power—can generate substantial forms (section III). The paper presents how this view was received by the next generation of philosophers, i.e., around 1350 (section IV), (...) and how, even though some of the initial theoretical motivations for this view were quickly abandoned, the view was still defended by several philosophers in the fifteenth and sixteenth centuries (section V). It is finally shown that this theory, still discussed by Suárez and early modern scholastics, and despite being generally rejected, contributed in its own way to the evolution of hylomorphism in the late Middle Ages and, to a certain extent, its gradual decline (section VI).

This paper offers an overview of the history of the axiom forma dat esse, which was commonly quoted during the Middle Ages to describe formal causality. The first part of the paper studies the origin of this principle, and recalls how the ambiguity of Boethius’s first formulation of it in the De Trinitate was variously interpreted by the members of the School of Chartres. Then, the paper examines the various declensions of the axiom that existed in the late Middle Ages, (...) and shows how its evolution significantly follows the progressive decline of the Aristotelian model of formal causality.

This paper aims at tracking down, by looking at late medieval and early modern discussions over the ontological status of artifacts, the main steps of the process through which nature became theorized on a mechanistic model in the early 17th century. The adopted methodology consists in examining how inventions such as mechanical clocks and automata forced philosophers to modify traditional criteria based on an intrinsic principle of motion and rest for defining natural beings. The paper studies different strategies designed in (...) the transitional period 1300–1600 for making these inventions compatible with classical definitions of nature and artifacts. In the first part of the paper, it is shown that, even if virtually all medieval philosophers acknowledged an ontological distinction between artifacts and natural beings, these different strategies demonstrate a growing concern about the consistency of the art/nature distinction. The next part of the paper studies how mechanical clocks, even before the Scientific Revolution, served as theoretical models for applying mechanistic views to different objects (be they cosmological, physical or biological). The epistemological function of clocks appears to stem from different factors (like the specific manufacturing of late medieval clocks as well as the evolution of 16th-century mechanics) that are listed in this second part of the paper. These factors, combined with the definitional issues raised by automata, explain that clocks became the symbol of a new approach to natural philosophy, characterized by the collapse of the art/nature distinction and the “mechanization of nature”.

Since its inception, philosophy has aroused both fascination and hostility. What is it about philosophy that provokes such contrasting emotions? Plato’s works offer a valuable opportunity to explore this question, not only because of the dialogue form, which makes it possible to present a range of attitudes toward the practice of philosophy, but also because of Plato’s persistent efforts to define, describe, and defend philosophy as a radically unique activity. In this paper, the author collects and organizes the evidence in (...) order to show that, although Plato presents a wide array of motives for hostility toward philosophy, these are all grounded upon some form of ignorance that is a source of pain. The author also shows how, in well-disposed individuals, a special kind of ignorance can become a source of love rather than hatred, and how these people experience a special kind of pleasure—the very pleasure of practicing and loving philosophy.

We study the finitely repeated prisoner’s dilemma in which the players are restricted to choosing strategies which are implementable by a machine with a bound on its complexity. One player has to use a finite automaton while the other player has to use a finite perceptron. Some examples illustrate that the sets of strategies which are induced by these two types of machines are different and not ordered by set inclusion. Repeated game payoffs are evaluated according to the limit of (...) means. The main result establishes that a cooperation at almost all stages of the game is an equilibrium outcome if the complexity of the machines the players may use is limited enough and if the length T of the repeated game is sufficiently large. This result persists when more than T states are allowed in the player’s automaton. We further consider a variant of the model in which the two players are restricted to choosing strategies which are implementable by perceptrons and prove that the players can cooperate at most of the stages provided that the complexity of their perceptrons is sufficiently reduced.

We introduce a new allocation rule, called the sequential equal surplus division for rooted forest TU-games. We provide two axiomatic characterizations for this allocation rule. The first one uses the classical property of component efficiency plus an edge deletion property. The second characterization uses standardness, an edge deletion property applied to specific rooted trees, a consistency property, and an amalgamation property. We also provide an extension of the sequential equal surplus division applied to the problem of sharing a river with (...) bifurcations. (shrink)

This collection is the first book-length study to re-evaluate all of James Joyce's major fictional works through the lens of cognitive studies. Cognitive Joyce presents Joyce's relationship to the scientific knowledge and practices of his time and examines his texts in light of contemporary developments in cognitive and neuro-sciences. The chapters pursue a threefold investigation—into the author's "extended mind" at work, into his characters' complex and at times pathological perceptive and mental processes, and into the elaborate responses the work elicits (...) as we perform the act of reading. This volume not only offers comprehensive overviews of the oeuvre, but also detailed close-readings that unveil the linguistic focus of Joyce's drama of cognition. (shrink)
