There is ample evidence from literature and clinical practice indicating mathematical difficulties in individuals with ADHD, even when there is no concomitant diagnosis of developmental dyscalculia. What factors underlie these difficulties is still an open question. Research on dyscalculia and neurotypical development suggests visual perception of numerosity (the number sense) as a building block for math learning. Participants with lower numerosity estimation thresholds (higher precision) are often those with higher math capabilities. Strangely, the role of numerosity perception in math skills (...) in ADHD has been neglected, leaving open the question whether math difficulties in ADHD also originate from a deficitary visual number sense. In the current study we psychophysically measured numerosity thresholds and accuracy in a sample of children/adolescents with ADHD, but not concomitant dyscalculia (N = 20, 8–16 years). Math abilities were also measured by tasks indexing different mathematical competences. Numerosity performance and math scores were then compared to those obtained from an age-matched control group (N = 20). Bayesian statistics indicated no difference between ADHD and controls on numerosity perception, despite many of the symbolic math tasks being impaired in participants with ADHD. Moreover, the math deficits showed by the group with ADHD remained substantial even when numerosity thresholds were statistically regressed out. Overall, these results indicate that math difficulties in ADHD are unlikely to originate from an impaired visual number sense. (shrink)

Gothic literature—a genre brimming with madness, supernaturalism, and psychological terror—offers innumerable case studies potentially representing how psychiatric patients perceive their treatment from healthcare professionals. Charlotte Perkins Gilman’s famous 1892 short story “The Yellow Wallpaper” offers a poignant example of this through its fictional narrator, a diarist many interpret to be suffering from postpartum depression. The fiction here does not stray far from reality: Gilman orchestrated her diarist’s experience to mirror her own, as both real author and fictional character suffocated from (...) a melancholy only made worse by their physicians’ insistence on following the “Rest Cure.” While this instruction to cease all work and activity was a prevalent depression treatment at the time, Gilman, through “The Yellow Wallpaper,” reveals how the intervention ultimately harmed more than helped because it overlooked her—and, by extension, her fictional diarist’s— unique needs and identities. Today, while the ineffective Rest Cure no longer exists, applying observations from “The Yellow Wallpaper” to clinical research calls attention to underrepresentation in treatment development, a costly problem that could be mitigated by mindful incorporation of intersectionality theory into study designs.

Network analysis views complex systems as networks with well-defined structural properties that account for their complexity. These characteristics, which include scale-free behavior, small worlds and communities, are not to be found in networks such as random graphs and lattices that do not correspond to complex systems. They provide therefore a robust ground for claiming the existence of “complex networks” as a non-trivial subset of networks. The theory of complex networks has thus been successful in making systematically explicit relevant marks of (...) complexity in the form of structural properties, and this success is at the root of its current popularity. Much less systematic has been, on the other hand, the definition of the properties of the building components of complex networks. The obvious assumption is that these components must be nodes and links. Generally, however, the internal structure of nodes is not taken into account, and links are serendipitously identified by the perspective with which one looks at the network to be analyzed. For instance, if the nodes are Web pages that contain information about scientific papers, one point of view will match the relevant links with hyperlinks to similar Web pages, and another with citations of other articles. We intend to contribute here a systematic approach to the identification of the components of a complex network that is based on information theory. The approach hinges on some recent results arising from the convergence between the theory of complex networks and probabilistic techniques for content mining. At its core there is the idea that nodes in a complex network correspond to basic information units from which links are extracted via methods of machine learning. Hence the links themselves are viewed as emergent properties, similarly to the broader structural properties mentioned above. Indeed, beside rounding up the theory, this approach based on learning has clear practical benefits, in that it makes networks emerge from arbitrary information domains. We provide examples and applications in a variety of contexts, starting from an information-theoretic reconstruction of the well-known distinction between “strong links” and “weak links” and then delving into specific applications such as business process management and analysis of policy making.

Physical appearance influences our perceptions, judgments, and decision making about others. While the current literature with regard to the perceptions and judgments of nondisabled people’s attractiveness is robust, the research investigating the perceived physical attractiveness and judgments of physically disabled individuals is scarce. Therefore, in the current study, we investigated whether people with physical disabilities are perceived by the opposite sex as more or less attractive relative to nondisabled individuals. Our results, based on over 675 participants, showed a positive effect (...) for women’s attractiveness ratings of men with physical disabilities, but not men’s attractiveness ratings of physically disabled women. Moreover, social desirability bias was positively associated with attractiveness ratings of physically disabled individuals, meaning those with higher tendency to be viewed favorably by others rated physically disabled individuals more attractive. Finally, our results revealed that attractiveness ratings of individuals with physical disabilities are positively associated with extroversion and empathy in both men and women, and positively with agreeableness and negatively with neuroticism in women. In conclusion, our study showed women rate men with physical disabilities as higher on attractiveness than nondisabled men, which is also influenced by their social desirability bias. (shrink)

The goal of this article is to take a step toward the resolution of the problem of finding an analytic sequent calculus for the logic of proofs. For this, we focus on the system Ilp, the intuitionistic version of the logic of proofs. First we present the sequent calculus Gilp that is sound and complete with respect to the system Ilp; we prove that Gilp is cut-free and contraction-free, but it still does not enjoy the subformula property. Then, we enrich (...) the language of the logic of proofs and we formulate in this language a second Gentzen calculus Gilp∗. We show that Gilp∗ is a conservative extension of Gilp, and that Gilp∗ satisfies the subformula property. (shrink)

We survey the literature that has explored the implications of decision-making under ambiguity for financial market outcomes, such as portfolio choice and equilibrium asset prices. This ambiguity literature has led to a number of significant advances in our ability to rationalize empirical features of asset returns and portfolio decisions, such as the failure of the two-fund separation theorem in portfolio decisions, the modest exposure to risky securities observed for a majority of investors, the home equity preference in international portfolio diversification, (...) the excess volatility of asset returns, the equity premium and the risk-free rate puzzles, and the occurrence of trading break-downs.

A cavallo tra i due concili di Costanza e Basilea, che hanno fortemente influito sul giudizio della Chiesa in relazione alle donne visionarie, si staglia la figura di Francesca Bussa dei Ponziani. Le visioni politiche di Francesca rappresentano un fulgido esempio di come i modelli brigidini e cateriniani siano stati ripresi e rimodellati su un nuovo, mutato contesto storico. La sua consolidata autorità le consentì di ammonire a più riprese papa Eugenio IV riguardo alla sua partecipazione al concilio (...) di Basilea, intervenendo attivamente nello scenario religioso e politico romano.

La tâche de cette contribution est de situer le traité de Philon d’Alexandrie Alexander vel De ratione quam habere etiam bruta animalia dans le panorama des options philosophiques antiques concernant le statut des animaux et d’interpréter les thèses spécifiques de l’auteur. Dans un premier temps, les positions de Philon et d’Alexandre, les protagonistes du traité, seront brièvement examinées. Ensuite, nous tenterons de retracer leur contexte philosophique : les thèses de Philon, qui exclut les animaux de la rationalité et de la (...) pertinence éthique, semblent faire écho aux positions stoïciennes et se démarquer de la tradition aristotélicienne et platonicienne, cette dernière étant assumée par Alexandre. Dans la dernière partie, l’analyse de cette hypothèse sera étendue à d’autres aspects du corpus philonien, liés surtout aux instances bibliques. Le but est de vérifier si, en dernière analyse, Philon peut être associé au stoïcisme impérial en ce qui concerne la domination homme-animal et au-delà. (shrink)

The volume Socrates and the Socratic Dialogue, recently edited by Ch. Moore and A. Stavru (Brill, 2018), favours the pluralistic approach to the sources that has gained increasing acceptance over the last decades, and thus shares the choice not to limit the study of Socrates to the canonical ‘quartet’ Aristophanes, Plato, Xenophon, and Aristotle. Indeed, the volume partly continues an existing trend, but at the same time proves to reinforce it by further refining and scrutinising this field of research. The (...) very welcome result is a collection of essays that provides a rich and nuanced picture of Socrates from the Old Comedy to Neoplatonism, based on Socratic literature as well as non-Socratic material – the latter including both non-Socratic authors and non-Socratic passages by Socratic authors. Because of the variety of themes and the number of contributions, which present a vast range of methodological approaches, the work offers a privileged point of view for investigating the ongoing advancements in our understanding of Socratism. Rather than providing a thorough presentation of all chapters, which would inevitably oversimplify their content, this paper attempts to highlight – also through the comparison with the existing literature – the main results of the analysis conducted and their specific contribution to the field.

The purpose of this randomized controlled study was to investigate the effects of a 12-week coordinative ability training program on adolescents’ cognitive functioning, using evaluation tests of visuospatial perception, attention, and working memory. We randomly assigned 60 public school students (14–15 years) to either an experimental coordinative abilities training (∼40 min twice/week) group (n= 30) or a control group (n= 30) who received general psycho-physical wellness training (∼40 min., twice a week). At baseline and after training we used two standardized (...) motor tests and a single cognitive measure (Corsi’s Block-tapping test) to assess students’ visuospatial perception, attention, and working memory. We found a significant Time x Group interaction for the Throwing and Catching Test and Corsi’s Block-Tapping test, reflecting a meaningful experimental group improvement (p< 0.001), and there were no significant pre-post changes found in the control group. Thus, a 12-week program of coordinative abilities was able to improve not only coordination skills but aspects of cognitive functioning relevant to academic achievement. (shrink)

The main purpose of Le Nouveau Cynée, published by Emeric Crucé in 1623, is to find a better way to establish an enduring peace in the whole world. This pacifist utopia is very interesting, because it contains for the first time the idea of avoiding war, by establishing an international arbitration court settled in Venice. The court is an assembly with representatives of all States, even the Turkish Empire. The assembly is called to discuss any kind of controversy which may (...) rise among the States and to vote for a solution. The Crucé’ work had a remarkable success immediately. It inspired many authors to reflect upon peace, but it then soon afterwards disappeared. (shrink)

During his multiannual reflection Sismondi seems reluctant to define his concept of city, while devoting most of his energy to the importance of cities self-government – starting with his famous Histoire des Républiques italiennes au Moyen Age. This essay tries to frame his reflection in the intersection between his economic and constitutional proposals. In the background stands a continuous dialogue with Adam Smith, revisited through the relationship that the canton of Geneva has had during the Restoration with its rural population.

Pregnancy is a one of the most complex phenomena of life and is essential to the life cycle of mammals. Pregnancy is also a crucial aspect of humans’ life and experience. But what is pregnancy? This question has received little attention in philosophy until recently, when it got picked up by metaphysicians and philosophers of science. However, the philosophical discussion is still in its infancy. This article provides a survey of the recent debate on the metaphysics of pregnancy. It explores (...) the relation between the pregnant organism and the gestated one, motivating the further study of pregnancy from a philosophical perspective (§1, §2). It summarises the three main models of pregnancy present in the literature, the containment view (§3), the parthood view (§4) and the splitting process view (§5) with their advantages and shortcomings. Then, it explores a recent debate on whether pregnancy is a disease (§6). Lastly, it considers how one can decide between these models, for instance by favouring a given view of biological individuality over another (§7). The article concludes that none of the views is fully satisfactory, and thus inviting to continue the research on pregnancy from a metaphysical and philosophical perspective. (shrink)

One central tenet of the Modern Evolutionary Synthesis , and the consensus view among biologists until now, is that all genetic mutations occur by “chance” or at “random” with respect to adaptation. However, the discovery of some molecular mechanisms enhancing mutation rate in response to environmental conditions has given rise to discussions among biologists, historians and philosophers of biology about the “chance” vs “directed” character of mutations . In fact, some argue that mutations due to a particular kind of mutator (...) mechanisms challenge the Modern Synthesis because they are produced when and where needed by the organisms concerned. This paper provides a defense of the Modern Synthesis’ consensus view about the chance nature of all genetic mutations by reacting to Jablonka and Lamb’s analysis of genetic mutations and the explicit Lamarckian flavor of their arguments. I argue that biologists can continue to talk about chance mutations according to what I call and define as the notion of “evolutionary chance,” which I claim is the Modern Synthesis’ consensus view and a reformulation of Darwin’s most influential idea of “chance” variation. Advances in molecular genetics are therefore significant but not revolutionary with respect to the Modern Synthesis’ paradigm. (shrink)

In this paper, we present a simple sequent calculus for the modal propositional logic S5. We prove that this sequent calculus is theoremwise equivalent to the Hilbert-style system S5, that it is contraction-free and cut-free, and finally that it is decidable. All results are proved in a purely syntactic way.

Biochemical kinds present an interesting case study in the philosophical literature on natural kinds and functions, as they fall between chemical kinds, defined by their intrinsic microstructural properties, and biological kinds, which involve functional and evolutionary considerations. Here we examine how the distinct chemical and functional properties of biochemical kinds are unified, as well as their identity criteria. We contend that unification principles are crucial for explaining the clustering of properties shared by members of natural kinds and for establishing identity (...) criteria for such kinds. We consider whether there are specific properties that characterize biochemical kinds. This entails investigating the relationship between biochemical functions and structure. We focus on proteins, particularly on vitamin B12, as a representative example of a biochemical kind. We conclude that if there are unification principles for biochemical kinds, these principles exist at the level of biochemistry itself. This supports the naturalness of biochemical kinds as genuine categories and provides identity conditions for such kinds. (shrink)

In Poggiolesi we have introduced a rigorous definition of the notion of complete and immediate formal grounding; in the present paper our aim is to construct a logic for the notion of complete and immediate formal grounding based on that definition. Our logic will have the form of a calculus of natural deduction, will be proved to be sound and complete and will allow us to have fine-grained grounding principles.

We give an introductory tutorial to assumption-based argumentation (referred to as ABA) – a form of argumentation where arguments and attacks are notions derived from primitive notions of rules in a deductive system, assumptions and contraries thereof. ABA is equipped with different semantics for determining ‘winning’ sets of assumptions and – interchangeably and equivalently – ‘winning’ sets of arguments. It is also equipped with a catalogue of computational techniques to determine whether given conclusions can be supported by a ‘winning’ set (...) of arguments. These are in the form of disputes between (fictional) proponent and opponent players, provably correct w.r.t. the semantics. Albeit simple, ABA is powerful in that it can be used to represent and reason with a number of problems in AI and beyond: non-monotonic reasoning, preferences, decisions. While doing so, it encompasses the expressive and computational needs of these problems while affording the transparency and explanatory power of argumentation. (shrink)

Typical theory of mind tasks assess children’s ability to attribute a false belief in order to predict or explain an action. According to these standard tasks, young children do not represent the independent (mistaken) beliefs of others until the fourth year—yet long before this, children are able to track speakers’ intentions in order to learn new words. Might communication be a privileged domain for theory of mind? In the present study we explored pre‐schoolers’ ability to track a false belief in (...) order to acquire a novel word. A puppet labeled a novel object in a false belief condition (contents of a box had been switched without her knowledge), and a true belief condition (contents switched in her presence). Children were significantly better at tracking the puppet’s false belief in the word‐learning task than in a standard false belief test. Possible reasons for this advantage are discussed, and the suggestion made that representation of mental states may emerge precociously in the service of communication. (shrink)

The goal of this article is to introduce a philosophical analysis of a widely neglected condition which affects between 3% and 18% of the population. People affected by this condition experience a lower level of wellbeing than the average population and are discriminated against in both their professional and their personal life. I will argue that this form of discrimination should be taken more seriously in philosophical debate and that social, legal and medical measures ought to be taken in order (...) to improve the quality of life of people affected by this condition.

Die Autorin analysiert die politische Konzeption des Messias als König und Gesetzgeber bei Maimonides in seinen Briefen, in Pereq Heleq sowie in Mishneh Torah. Besonderes Augenmerk liegt auf folgenden Schwerpunkten: a) die Konzeption des König-Philosophen bei Platon und Aristoteles; b) die karäischen Einflüsse auf Pereq Heleq sowie die Einflüsse der Mu'taziliten und der Ash'ariten durch die karäische Vermittlung; c) die individuelle und gemeinschaftliche Dimension des ́olam ha-ba im Werk Maimonides'; d.) die Beziehung zwischen Philosophie und Gesetz im Mishneh Torah und (...) deren eschatologische Konzeption im Vergleich zu Al-Farabis politischen und religionsphilosophischen Werken. Die Analyse basiert auf einer ausführlichen Lektüre der jüdischen, arabischen und judäoarabischen Quellen. Ziel der Autorin ist es, eine Lücke zu schließen in der politisch-philosophischen Kette zwischen Platon, Aristoteles, Al-Farabi und Maimonides in Bezug auf den messianischen König. Anhand der Denkstrukturen der jüdisch-islamischen Epoche zwischen dem 8. und dem 12. Jahrhundert wird der politische Charakter des König-Messias sowie seine spezifische Darstellung im intellektuellen Milieu von Maimonides konstruiert. (shrink)

L’article analyse les témoignages stoïciens qui définissent la divinité comme «intellect» et comme «âme du monde», et qui permettent de déterminer les contenus de la pensée divine comme logoi, c’est-à-dire certains «discours» ou «raisonnements». En premier lieu, on examine les mots νοερόν, et νοητόν pour établir à quelles réalités les Stoïciens confèrent les caractères d’intelligence et d’intelligibilité et comment ils décrivent la pensée scientifique à laquelle ils comparent la pensée divine. En second lieu, on examine la théorie des raisons séminales (...) et ses relations historiques avec le problème des objets de la pensée divine. Enfin, on tente de montrer que les Stoïciens, tout en suivant la théologie démiurgique du Timée, unifient ce que Platon a tenu bien séparé : le Démiurge lui-même, l’âme du monde, le «vivant intelligible».
