Prism Adaptation is a useful method to study the mechanisms of sensorimotor adaptation. After-effects following adaptation to the prismatic deviation constitute the probe that adaptive mechanisms occurred, and current evidence suggests an involvement of the cerebellum at this level. Whether after-effects are transferable to another task is of great interest both for understanding the nature of sensorimotor transformations and for clinical purposes. However, the processes of transfer and their underlying neural substrates remain poorly understood. Transfer from throwing to pointing is (...) known to occur only in individuals who had previously reached a good level of expertise in throwing, not in novices. The aim of this study was to ascertain whether anodal stimulation of the cerebellum could boost after-effects transfer from throwing to pointing in novice participants. Healthy participants received anodal or sham transcranial direction current stimulation of the right cerebellum during a PA procedure involving a throwing task and were tested for transfer on a pointing task. Terminal errors and kinematic parameters were in the dependent variables for statistical analyses. Results showed that active stimulation had no significant beneficial effects on error reduction or throwing after-effects. Moreover, the overall magnitude of transfer to pointing did not change. Interestingly, we found a significant effect of the stimulation on the longitudinal evolution of pointing errors and on pointing kinematic parameters during transfer assessment. These results provide new insights on the implication of the cerebellum in transfer and on the possibility to use anodal tDCS to enhance cerebellar contribution during PA in further investigations. From a network approach, we suggest that cerebellum is part of a more complex circuitry responsible for the development of transfer which is likely embracing the primary motor cortex due to its role in motor memories consolidation. This paves the way for further work entailing multiple-sites stimulation to explore the role of M1-cerebellum dynamic interplay in transfer. (shrink)

ABSTRACT This article examines the impact of Robert Owen’s educational ideas in France. It traces how his ideas attracted the attention of French liberals, particularly Charles de Lasteyrie, Alexandre de Laborde and Joseph-Marie de Gérando, and republicans associated with Marc-Antoine Jullien’s Revue Encyclopédique. The article focuses in particular on the work of one of Owen’s early French followers, the leading radical egalitarian political and social theorist Joseph Rey (1779–1855). The article examines how Owen’s reflections on education served as the (...) foundation for Rey’s own theoretical and practical contributions to educational philosophy and pedagogical reform. Drawing extensively from unpublished archive material, the article describes and analyses Rey’s detailed egalitarian critique of the work of educational theorist Joseph Jacotot, and explores how Rey advanced a far more ambitious philosophy of education that, when translated into practice, eliminated the traditional divide between manual skills and intellectual ability, resulting in a genuinely inclusive and comprehensive educational system.

To Aristotle, spoken words are symbols, not of objects in the world, but of our mental experiences related to these objects. Presently there are two major strands of interpretation of Aristotle’s concept of the linguistic sign. First, there is the structuralist account offered by Coseriu (Geschichte der Sprachphilosophie. Von den Anfängen bis Rousseau, 2003 [1969], pp. 65–108) whose interpretation is reminiscent of the Saussurean sign concept. A second interpretation, offered by Lieb (in: Geckeler (Ed.) Logos Semantikos: Studia Linguistica in Honorem (...) Eugenio Coseriu 1921–1981, 1981) and Weidemann (in: Schmitter (Ed.) Geschichte der Sprachtheorie 2. Sprachtheorien der abendländischen Antike, 1991), says that Aristotle’s concept of the linguistic sign is similar to the one presented in Ogden and Richard’s (The meaning of meaning: A study of the influence of language upon thought and of the science of symbolism, 1970 [1923]) semiotic triangle. This paper starts off with an introductory outline of the so-called phýsei-thései discussion which started during presocratic times and culminated in Plato’s Cratylus. Aristotle’s concept of the linguistic sign is to be regarded as a solution to the stalemate position reached in the Cratylus. Next, a discussion is offered of both Coseriu’s and Lieb’s analysis. We submit that Aristotle’s concept of the linguistic sign shows features of both Saussure’s and Ogden and Richards’s sign concept but that it does not exclusively predict one of the two. We argue that Aristotle’s concept of the linguistic sign is based on three different relations which together evince his teleological as well empiricist point of view: one internal (symbolic) relation and two external relations, i.e. a likeness relation and a relation katà synthéken.

This article focuses on defective conditionals ? namely indicative conditionals whose antecedents are false and whose truth-values therefore cannot be determined. The problem is to decide which formal connective can adequately represent this usage. Classical logic renders defective conditionals true whereas traditional mathematics dismisses them as irrelevant. This difference in treatment entails that, at the propositional level, classical logic validates some sentences that are intuitively false in plane geometry. With two proofs, I show that the same flaw is shared by (...) a family of trivalent logics. I go on to examine the strict conditional and its derivatives. This family is the only one to avoid the faulty inference but it does so without addressing the status of the truth-value assigned to defective conditionals. (shrink)

. Computational chemistry grew in a new era of “desktop modeling,” which coincided with a growing demand for modeling software, especially from the pharmaceutical industry. Parameterization of models in computational chemistry is an arduous enterprise, and we argue that this activity leads, in this specific context, to tensions among scientists regarding the epistemic opacity transparency of parameterized methods and the software implementing them. We relate one flame war from the Computational Chemistry mailing List in order to assess in detail the (...) relationships between modeling methods, parameterization, software and the various forms of their enclosure or disclosure. Our claim is that parameterization issues are an important and often neglected source of epistemic opacity and that this opacity is entangled in methods and software alike. Models and software must be addressed together to understand the epistemological tensions at stake. (shrink)

In a previous article on cosmological arguments, I have put forward a few examples of complete infinite and circular explanations, and argued that complete non-wellfounded explanations such as these might explain the present state of the world better than their well-founded theistic counterparts (Billon, 2021). Although my aim was broader, the examples I gave there implied merely causal explanations. In this article, I would like to do three things: • Specify some general informative conditions for complete and incomplete non-wellfounded causal (...) explanations that can be used to assess candidate explanations and to generate new examples of complete non-wellfounded explanations. • Show that these conditions, which concern chains of causal explanations, easily generalize to chains of metaphysical, grounding explanations and even to chains involving other “determination relations” such as supervenience. • Apply these general conditions to the recent debates against the existence of nonwellfounded chains of grounds and show, with a couple of precise examples, that the latter can be complete, and that just like in the case of causal explanations, non-wellfoundedness can in fact be an aset rather than a liability.

Cet article traite du rapport de l’engagement et de la connaissance sociologique, en prenant pour terrain la problématique des rapports sociaux de sexe et le féminisme. Plus exactement, c’est la question de l’utopie et de sa fonction heuristique et cognitive éventuelle pour la recherche qui fait l’objet de l’étude. Après avoir rappelé et présenté certains des travaux les plus importants sur la question, il est procédé à une tentative d’élucidation des vertus cognitives de l’utopie féministe matérialiste pour les recherches sur (...) le genre, la différence des sexes et la domination masculine. La conclusion revient sur les implications épistémologiques et méthodologiques de cette étude.This article is devoted to the study of the relationship between engagement and sociological knowledge, in the field of research relevant to gender and feminism. More exactly, the question concerns the heuristic and cognitive functions of utopia. Firstly, the author introduces some of the most significant works on the subject. Then, he tries to clarify the cognitive virtues of the feminist utopia for a better understanding of gender, sex difference and male domination. The conclusion reconsiders the epistemological and methodological implications of the study. (shrink)

The key to this study lies in my own identity as a researcher who specializes in the fifteenth century and Franciscan reforms, especially the confrontation in eastern Central Europe between the theory of the via media based on a return to the Martianian Constitutions, and the Observance sub vicariis brought by Giovanni of Capistrano when he crossed the Alps in 1451.2 The major aspect of this is a view on the “pre-history” of the Libellus ad Leonem, which was written in (...) 1513 by Paolo Giustiniani and Pietro Quirini in preparation of the Fifth Lateran Council. This “pre-history” concerns a century of transformations of the links between the Observant reforms, humanist culture and the.. (shrink)

Ramsey’s theorem asserts that every k-coloring of $[\omega ]^n$ admits an infinite monochromatic set. Whenever $n \geq 3$, there exists a computable k-coloring of $[\omega ]^n$ whose solutions compute the halting set. On the other hand, for every computable k-coloring of $[\omega ]^2$ and every noncomputable set C, there is an infinite monochromatic set H such that $C \not \leq _T H$. The latter property is known as cone avoidance.In this article, we design a natural class of Ramsey-like theorems encompassing (...) many statements studied in reverse mathematics. We prove that this class admits a maximal statement satisfying cone avoidance and use it as a criterion to re-obtain many existing proofs of cone avoidance. This maximal statement asserts the existence, for every k-coloring of $[\omega ]^n$, of an infinite subdomain $H \subseteq \omega $ over which the coloring depends only on the sparsity of its elements. This confirms the intuition that Ramsey-like theorems compute Turing degrees only through the sparsity of its solutions. (shrink)

En este artículo me propongo abordar el problema del tiempo en las sociedades contemporáneas desde un diálogo entre las construcciones teóricas de Moishe Postone y Hartmut Rosa y el trabajo de Michel Foucault. Los dos primeros se han centrado en explicar cómo la temporalidad se ha convertido en un tipo de dominación abstracta, impersonal y cuasiobjetiva a partir de conceptos como la densificación temporal, la aceleración o la hibridación. Foucault, en cambio, concibe el tiempo bajo el prisma de la racionalidad (...) política neoliberal, por la cual el tiempo pasa a ser un recurso que debe gestionarse por los sujetos en términos empresariales y que termina por configurar una ética neoliberal de la administración del tiempo. Este diálogo ejemplifica de manera privilegiada la tensión entre la coacción o la presión temporal y la administración estratégica del tiempo propia de las sociedades contemporáneas. (shrink)

The question of the Hegelian heritage within the Marxian dialectic is a classic one that is still an open one, after more than a century of fruitful and various inquiry. In order to tackle the issue from a new perspective, we must first distinguish between, on the one hand, the subjective dialectic, or logic of Marxian thought, which is clearly inherited from Hegel, and, on the other hand, the objective dialectic, or logic of reality itself, which Marx arrived at by (...) way of a frontal opposition to his master, even as he took up the latter’s “rational kernel” in order to invert it, substituting for Hegel’s idealist philosophy of creation a materialist conception of production and replacing the logic of negativity by a logic of produ-activity. Thus conceptualized by Marx, the gnoseological dialectic and dialectical materialism interact rationally. This enables us to renew the foundations of a dialectical materialism. Unrelated to stalinist « diamat », such a conception is well equipped to demonstrate its effectiveness for the knowledge and understanding of realities, both in terms of their irreducible material singularity, apprehended according to their constitutive historicity, and as elements of a certain real totality which is in process.

Computational reproducibility possesses its own dynamics and narratives of crisis. Alongside the difficulties of computing as an ubiquitous yet complex scientific activity, computational reproducibility suffers from a naive expectancy of total reproducibility and a moral imperative to embrace the principles of free software as a non-negotiable epistemic virtue. We argue that the epistemic issues at stake in actual practices of computational reproducibility are best unveiled by focusing on software as a pivotal concept, one that is surprisingly often overlooked in accounts (...) of reproducibility issues. Software is not only about designing and coding but also about maintaining, supporting, distributing, licensing, and governance; it is not only about developers but also about users. We focus on openness debates among computational chemists involved in molecular modeling software packages as empirical grounding for our argument. We then identify and analyse four epistemic characteristics as key to the role of software in computational reproducibility. (shrink)

Although robots can contribute to the understanding of biological behavior, they fail to model the processes by which humans cope with their environment. Both development and learning are characterized by complex relationships that require constant modification. Given present technology, robots can only model behaviors in specific situations and during discrete stages. Robots cannot master the complex relationships that are the hallmark of human behavior.

A function is diagonally non-computable if it diagonalizes against the universal partial computable function. D.n.c. functions play a central role in algorithmic randomness and reverse mathematics.

Patients suffering from depersonalization complain of feeling detached from their body, their mental states, and actions or even from themselves. In this chapter, I argue that depersonalization consists in the lack of a phenomenal feature that marks my experiences as mine, which is usually called “mineness,” and that the study of depersonalization constitutes a neglected yet incomparable probe to assess empirically the scope, role, and even the nature of mineness. Here is how I will proceed. After describing depersonalization (§2) and (...) arguing that it involves a lack of mineness (§3) I will confront a series of objections (§4). I will then spell out what depersonalization can teach us about the scope of mineness (§5), about its role and psychological function (§6) and even about its nature (§7). (shrink)

Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, (...) 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website. (shrink)

ABSTRACT Legal certainty is a central requirement for the rule of law. Legal systems should both enable those subject to law to predict human behaviour and institutional reactions and to prevent an arbitrary use of state power against them. The value of legal certainty is usually conceived as a formal value opposed to the values of freedom or equality. The purpose of this paper is to discuss this idea and to explore a less formal conception of the value of legal (...) certainty. In this sense, I will argue that we need to depart from a purely formal understanding of the requirements imposed by such value and to consider the need to provide them with a substantive content. So, legal certainty is not completely independent of legal substantive justice and it implies that it is impossible to define ex ante which concrete aspects of justice should not be the law’s concern.

The horse was essential to past human societies but became a recreational animal during the twentieth century as the world became increasingly mechanized. As the author reviews here, recent studies of ancient genomes have revisited the understanding of horse domestication, from the very early stages to the most modern developments. They have uncovered several extinct lineages roaming the far ends of Eurasia some 4000 years ago. They have shown that the domestic horse has been significantly reshaped during the last millennium (...) and experienced a sharp decline in genetic diversity within the last two centuries. At a time when no truly wild horses exist any longer, this calls for enhanced conservation in all endangered populations. These include the Przewalski's horse native to Mongolia, and the many local breeds side‐lined by the modern agenda, but yet representing the living heritage of over five millennia of horse breeding.

A better understanding of media effects on immigration attitudes is crucial for policy development and innovation. While many studies have focused on immigration discourses or the salience of this issue in print media and broadcast TV, few have looked at how different “media diets” influence immigration attitudes. Using two-wave panel data composed of 14,480 observations (7,240 individuals) from nine EU countries, this article specifically analyses the role of online and social media news consumption as well as media diet diversity on (...) Europeans’ perceptions of the economic and cultural impact of immigration. The results show that relying primarily on online or social media (compared to print newspapers) to get news, consuming news less frequently, or having a less diverse media diet all significantly and negatively influence people’s perceptions of the impact of immigration. Results and implications are discussed in light of today’s changing media landscape and news consumption habits. (shrink)
