This paper describes our general framework for the investigation of how human gestures can be used to facilitate the interaction and communication between humans and robots. Two studies were carried out to reveal which “naturally occurring” gestures can be observed in a scenario where users had to explain to a robot how to perform a home task. Both studies followed a within-subjects design: participants had to demonstrate how to lay a table to a robot using two different methods — utilizing (...) only gestures or gestures and speech. The first study enabled the validation of the COGNIRON coding scheme for human gestures in Human–Robot Interaction. Based on the data collected in both studies, an annotated video corpus was produced and characteristics such as frequency and duration of the different gestural classes have been gathered to help capture requirements for the designers of HRI systems. The results from the first study regarding the frequencies of the gestural types suggest an interaction between the order of presentation of the two methods and the actual type of gestures produced. However, the analysis of the speech produced along with the gestures did not reveal differences due to ordering of the experimental conditions. The second study expands the issues addressed by the first study: we aimed at extending the role of the interaction partner by introducing some positive acknowledgement of the participants’ activity. The results show no significant differences in the distribution of gestures between the two explanation methods, in contrast to the previous study. Implications for HRI are discussed focusing on issues relevant for the design of the robot’s communication skills to support the interaction loop with humans in home scenarios. (shrink)

The relationship between students and higher education is seen to have become increasingly transactional. We approach the study of the student–HE relationship in a novel way, by focusing on students’ behaviour post-university, rather than on student narratives. Conceptually, the article builds on multidimensional views of student engagement and the differentiation between psychological transactional contracts – where students who achieve better academic results are more likely to donate – and relational contracts – where students donate more following engagement in social experiences. (...) Making use of longitudinal data on donation behaviour from over 50,000 alumni from an English university over two decades, we find that while students who get better degree outcomes are more likely to donate, the association between participation in social experiences and donations is much stronger. This questions prevalent transactional models of HE and underlines the limitations of purely consumerist views of the relation between students and higher education institutions, even in the marketized UK context.

Boffa non-well-founded set theory allows for several distinct sets equal to their respective singletons, the so-called ‘Quine atoms’. Rieger contends that this theory cannot be a faithful description of set-theoretic reality. He argues that, even after granting that there are non-well-founded sets, ‘the extensional nature of sets’ precludes numerically distinct Quine atoms. In this paper we uncover important similarities between Rieger’s argument and how non-rigid structures are conceived within mathematical structuralism. This opens the way for an objection against Rieger, whilst (...) affording the theoretical resources for a defence of Boffa set theory as a faithful description of set-theoretic reality. (shrink)

In John Etchemendy's book, The Concept of Logical Consequence, several arguments are put forth against the standard model‐theoretic account of logical consequence and logical truth. I argue in this article that crucial parts of Etchemendy's attack depend on a failure to distinguish two senses of logic and two correlative senses of being something a logical question. According to one of these senses, the logic of a language, L, is the set of logical truths of L. In the other sense, logic (...) is a theoretical discipline whose aim is to characterize logical properties and it can be identified with the set of sentences on what, and why, the extension of the set of logical truths of a particular language is. Some particular claims by Etchemendy about the status assigned to the axiom of infinity in the model‐theoretic account are criticized and shown to be erroneous because of that conflation. (shrink)

Theistic modal realism argues for an extension of Lewis's modal realism capable of accommodating a theistic God. By affording elegant solutions to many atheistic challenges, the view is of great theoretical utility for the theist. However, it has been objected that within a Lewisian framework God cannot be causally efficacious on pain of collapsing intuitively distinct modal notions. In this article I explain why these worries are ill-founded and show how God's existence and causal power over the pluriverse can be (...) consistently understood. If successful, the proposal offers a congenial theistic way to adopt modal realism and address the atheological problems. (shrink)

In the field of cybernetic systems and more specifically in robotics, one of the fundamental objectives is the detection of anomalies in order to minimize loss of time. Following this idea, this paper proposes the implementation of a Hybrid Intelligent System in four steps to impute the missing values, by combining clustering and regression techniques, followed by balancing and classification tasks. This system applies regression models to each one of the clusters built on the instances of data set. Subsequently, a (...) variety of balancing techniques are applied to improve the classifier’s ability to discern whether it is in an error or a normal state. These techniques support to obtain better classification ratios in which a robot is close to error and allow us to bring the behavior back to a normal state. The experimentation is performed using a modern and public data set, which has been extracted from a component-based robotic system, in which different anomalies are induced by software in their components.

As it is well known, mobile phones have become a basic gadget for any individual that usually stores sensitive information. This mainly motivates the increase in the number of attacks aimed at jeopardizing smartphones, being an extreme concern above all on Android OS, which is the most popular platform in the market. Consequently, a strong effort has been devoted for mitigating mentioned incidents in recent years, even though few researchers have addressed the application of visualization techniques for the analysis of (...) malware. Within this field, the present work proposes the extension of a new technique called Hybrid Unsupervised Exploratory Plots to visualize Android malware datasets. More precisely, the novel Beta-Hebbian Learning (BHL) method is applied for the first time and validated under the frame of Hybrid Unsupervised Exploratory Plots, in conjunction with clustering methods. The informative visualization achieved provides a picture of the structure of the malware families, allowing subsequent analysis of their organization. To validate the Hybrid Unsupervised Exploratory Plot extension and its tuning, the popular Android Malware Genome dataset has been used in the experimental setting. Promising results have been obtained, suggesting that BHL applied in combination with clustering techniques in Hybrid Unsupervised Exploratory Plots are a viable resource for the visualization of malware families.

The phenomenological reading of psychoanalysis undertook by Michel Henry is surprising in several ways. By inscribing Freud in the philosophical lineage and by affirming that his theses on the unconscious take over (resume), ignoring it, two opposite movements of western metaphysics, Henry intends to show that psychoanalysis has to overcome the primacy of representation in order to get rid of the contradictions that traverse it and that make it a prisoner of a philosophy of consciousness. Without fully rejecting the Freudian (...) theory, the author of the Genealogy of Psychoanalysis reformulates the meaning of the meta-psychological notions according to his theses on the cogito, subjectivity and the auto-affection of the living. In this article we retraced the stakes of this redefinition of drives, affect and the unconscious considering his reflexions on repression. (shrink)

Criticisms of the “container” model of pregnancy picturing female and embryo as separate entities multiply in various philosophical and scientific contexts during the last decades. In this paper, we examine how this model underlies received views of pregnancy in evolutionary biology, in the characterization of the transition from oviparity to viviparity in mammals and in the selectionist explanations of pregnancy as an evolutionary strategy. In contrast, recent evo-devo studies on eutherian reproduction, including the role of inflammation and new maternal cell (...) types, gather evidence in favor of considering pregnancy as an evolved relational novelty. Our thesis is that from this perspective we can identify the emergence of a newhistoricalindividual in evolution. In evo-devo, historical units are conceptualized as evolved entities which fulfill two main criteria, their continuous persistence and their non-exchangeability. As pregnancy can be individuated in this way, we contend that pregnant females are historical individuals. We argue that historical individuality differs from, and coexists with, other views of biological individuality as applied to pregnancy (the physiological, the evolutionary and the ecological one), but brings forward an important new insight which might help dissolve misguided conceptions.

Mainstream game theory explains cooperation as the outcome of the interaction of agents who permanently pursue their individual goals. Amartya Sen argues instead that cooperation can only be understood by positing a type of rule-following behaviour that can be out of phase with the pursuit of individual goals, due to the existence of a collective identity. However, Sen does not clarify the ontological preconditions for the type of social behaviour he describes. I will argue that Sen's account of collective identity (...) can be best interpreted in the light of John Searle's notion of collective intentionality, while Sen's explanation of rule-following behavior and agency is best understood using the critical realist transformational model of social activity.

This book approaches classic epistemological problems from a contextualist perspective. The author takes as his point of departure the fact that we are situated beings, more specifically that every single moment in our lives is already given within the framework of a specific context in the midst of which we understand ourselves and what surrounds us. In the process of his investigation, the author explores, in a fresh way, the works of key thinkers in epistemology. These include Bernard Bolzano, René (...) Descartes, Gottlob Frege, Edmund Husserl, Immanuel Kant and Ludwig Wittgenstein, but also contemporary authors such as Stewart Cohen, Keith DeRose, David Lewis, Duncan Pritchard, Ernest Sosa and Charles Travis. Some of the topics covered are attributions of knowledge, the correspondence theory of truth, objectivity and subjectivity, possible worlds, primary and secondary evidence, scepticism, transcendentalism and relativism. The book also introduces a new contextualist thought-experiment for dealing with moral questions. Contextualism has received a great deal of attention in contemporary epistemology. It has the potential to resolve a number of issues that traditional epistemological approaches cannot address. In particular, a contextualist view opens the way to an understanding of those cognitive processes that require situational information to be fully grasped. However, contextualism poses serious difficulties in regard to epistemic invariance. This book offers readers an innovative approach to some fundamental questions in this field. (shrink)

While the notion of chance has been central in discussions over the probabilistic nature of natural selection and genetic drift, its role in the production of variants on which populational sampling takes place has received much less philosophical attention. This article discusses the concept of chance in evolution in the light of contemporary work in evo-devo. We distinguish different levels at which randomness and chance can be defined in this context, and argue that recent research on variability and evolvability demands (...) a causal understanding of variational probabilities under which development acquires a creative, rather than a constraining role in evolution. We then provide a propensity interpretation of variational probabilities that solves a conceptual confusion between causal properties, variational probabilities and extant variation present in the literature, and explore some metaphysical consequences that follow from our interpretation, specifically with regards to the nature of developmental types. 2.1Mutational randomness 2.2Morphological randomness 2.3Adaptive randomness3Variability and Phenotypic Probabilities 3.1The RNA model as a model for evo-devo4Evolvability and the Probability of Evolving5Variational Propensities in Evo-Devo 5.1Individuating variational propensities 5.2Developmental types6Conclusion.

We describe the role of morphosyntactic categories and syntactic dependencies in the process of semantically interpreting composite expressions. Special attention will be paid to the combinatorial properties conveyed by morphosyntactic categories such as nominals and verbs, as well as by syntactic dependencies like subject, direct object, or nominal modification. The semantic characterisation of these grammatical structures is based on cognitive abilities and abstract conceptualisations. This will provide us with theoretical arguments to review and extend some basic assumptions of Cognitive Grammar (...) and related work. (shrink)

Psychodrama is an effective psychotherapeutic model but interventions with adolescents require age-tailored techniques that maximize engagement and facilitate communication processes. This study describes a novel adaptation of a therapeutic mask technique to psychodrama with adolescents. Over the course of eight group sessions of psychodrama, five adolescents created their own mask and explored its therapeutic use. Their experiences were captured at the end of each session with the Helpful Aspects of Therapy form, and at the end of the study with the (...) Clinical Change Interview. Awareness/insight/self-understanding, empowerment and relief were the most significant aspects experienced by the adolescents, along with perceived increase of calmness and world connection, satisfaction in interpersonal communication and better emotional expression and regulation. The mask technique was experienced as a playful and engaging task that facilitated insight and interpersonal communication. Findings provide preliminary evidence on the clinical utility of mask-based psychodrama with adolescents. (shrink)

Entre os muitos textos em que Leibniz introduz e apresenta o princípio de razão suficiente está, como se sabe, o do parágrafo 7 dos Princípios da Natureza e da Graça. O texto diz: "Jusqu'icy nous n'avons parlé qu'en simples Physiciens : maintenant il faut s'elever à la Metaphysique, en nous servant du Grand Principe, peu employé communement, qui porte que rien ne se fait sans raison suffisante, c'est à dire que rien n'arrive, sans qu'il soit possible à celuy qui connoitroit (...) assés les choses, de rendre une Raison qui suffise pour determiner, pourquoy il en est ainsi, et non pas autrement. Ce principe posé, la premiere question qu'on a droit de faire, sera, Pourquoy il y a plustôt quelque chose que rien? Car le rien est plus simple et plus facile que quelque chose. De plus, supposé que des choses doivent exister, il faut qu'on puisse rendre raison, pourquoy elles doivent exister ainsi, et non autrement". O texto é evidentemente muito denso e inclui uma enorme multiplicidade de aspectos que deveriam ser analisados, por exemplo, o pouco uso que se faz de um princípio que, todavia, está sempre presente em tudo o que pensamos e fazemos; o facto de ter de haver uma razão para haver algo e para haver o que há; o facto de o nada ser mais fácil do que o ente; que se entende, afinal, por razão, que é que queremos dizer quando dizemos que há razão para qualquer coisa; que é que a noção de suficiência acrescenta à noção de razão, etc. O problema é, aliás, bem actual. D. Parfit, em On What Matters, escreve logo na primeira página do primeiro capítulo: "It is hard to explain the concept of reason, or what the phrase 'a reason' means. Facts give us reasons, we might say, when they count in favour of our having some attitude, or our acting in some way. But 'counts in favour of' means roughly 'gives a reason for'. Like some other fundamental concepts, the concept of a reason is indefinable in the sense that it cannot be helpfully explained merely by using words". Ou seja, não é claro a que é que corresponde a noção de razão, e apesar de Parfit ignorar tranquilamente o que a tradição pensou sobre o assunto, pode valer a pena regressar a Leibniz, também porque Leibniz se vangloria com frequência de dizer que o princípio de razão suficiente é o seu princípio.

The main goal of this paper is to contribute to the clarification of the dialectics between compatibilists and incompatibilists on free action. I describe a new incompatibilist position that has been neglected in the literature. I also provide a proper rationale for such a position. First, I present a justification for incompatibilism that is composed of an old idea and a new one. The old idea is the FRAP principle: freedom requires alternative possibilities. Compatibilists and incompatibilists alike usually share a (...) Key Assumption about how the open alternative possibilities allowed by indeterminism are supposed to support the libertarian case: the existence of alternative possibilities should make a metaphysically relevant difference concerning the control and/or the authorship of the agent over the action. The other component in the justification for incompatibilism is the rejection of the Key Assumption. Why to preserve FRAP when the Key Assumption is dropped? The answer has three parts: we have a strong pre-theoretical intuition in favour of FRAP; a crucial anti-libertarian argument, known as the Luck Argument, can be interpreted as showing that FRAP and the Key Assumption cannot both be true; the Luck Argument doesn't work when directed against FRAP itself.

The notion of fitness is usually equated to reproductive success. However, this actualist approach presents some difficulties, mainly the explanatory circularity problem, which have lead philosophers of biology to offer alternative definitions in which fitness and reproductive success are distinguished. In this paper, we argue that none of these alternatives is satisfactory and, inspired by Mumford and Anjum’s dispositional theory of causation, we offer a definition of fitness as a causal dispositional property. We argue that, under this framework, the distinctiveness (...) that biologists usually attribute to fitness—namely, the fact that fitness is something different from both the physical traits of an organism and the number of offspring it leaves—can be explained, and the main problems associated with the concept of fitness can be solved. Firstly, we introduce Mumford and Anjum's dispositional theory of causation and present our definition of fitness as a causal disposition. We explain in detail each of the elements involved in our definition, namely: the relationship between fitness and the functional dispositions that compose it, the emergent character of fitness, and the context-sensitivity of fitness. Finally, we explain how fitness and realized fitness, as well as expected and realized fitness are distinguished in our approach to fitness as a causal disposition. (shrink)

This article provides a critical reexamination of Blaise Pascal’s fragment on the “eternal silence of infinite spaces”, challenging the conventional objections, notably those by Paul Valéry. It presents an analytical journey through the philosophical and existential dimensions of Pascal’s text, exploring the unique interplay between human solitude and cosmic silence. The discussion navigates the intricate relationship between individual perception and the overarching sense of existential dread evoked by the universe’s vastness. This exploration is enriched by contrasting Pascal’s insights with broader (...) philosophical contexts, including references to Kierkegaard and the concept of the ‘music of the spheres’. Ultimately, the paper offers a nuanced interpretation of Pascal’s work, emphasizing its enduring relevance in understanding the human condition within the unfathomable expanse of the universe.

Assuming that Aristotelian ethical thought is specifically related to the problem of stability and permanency of Polis, this paper researches the relationship between the human soul and the ethical-political order. Ethical life is described as an on-going process whereby we learn how to think and desire, due to the experience of each particular situation. Ethics shows the human life as a progressive assimilation of ethical-political order in which one becomes the man one is. But, on the other hand, it also (...) shows that any order owes itself to the character of men who take part in it. Interiorising of customs – the purpose of ethical process of personal constitution – forms the man (character is built from the communitarian experience). The virtuous man’s soul is the strongest guarantee againstruination that always threatens Polis. The affirmation of a good life as a happy life in virtue – as the permanent and stable activity according to virtue – assures political order’s stability and the permanence of the Polis. This leads to a reflection about how much Politics owes Ethics: the possibility of the most esteemed idea in Aristotelian political discourse (the permanence of Polis) depends on the ethical process of human soul’s construction. The soul belongs to the order just as the order belongs to the soul. Seen as a virtue, Justice is a certain configuration of the soul (of desiring, thinking and even of feeling) of a man. The abandonment of that incarnate old conception of Justice is strictly related to the contemporary crisis of Law, whose weaknesses in legitimacy and efficacy are evident. (shrink)

The focus of social simulation on representing the social world calls for an investigation of whether its implementations are inherently value-laden. In this article, I investigate what kind of thing implementation is in social simulation and consider the extent to which it has moral significance. When the purpose of a computational artefact is simulating human institutions, designers with different value judgements may have rational reasons for developing different implementations. I provide three arguments to show that different implementations amount to taking (...) moral stands via the artefact. First, the meaning of a social simulation is not homogeneous among its users, which indicates that simulations have high interpretive malleability. I place malleability as the condition of simulation to be a metaphorical vehicle for representing the social world, allowing for different value judgements about the institutional world that the artefact is expected to simulate. Second, simulating the social world involves distinguishing between malfunction of the artefact and representation gaps, which reflect the role of meaning in simulating the social world and how meaning may or not remain coherent among the models that constitute a single implementation. Third, social simulations are akin to Kroes’ techno-symbolic artefacts, in which the artefact’s effectiveness relative to a purpose hinges not only on the functional effectiveness of the artefact’s structure, but also on the artefact’s meaning. Meaning, not just technical function, makes implementations morally appraisable relative to a purpose. I investigate Schelling’s model of ethnic residential segregation as an example, in which different implementations amount to taking different moral stands via the artefact. (shrink)

Neste artigo analisa‑se a Máxima de La Rochefoucauld “l’esprit est toujours la dupe du coeur”. O esclarecimento da noção de coração passa por uma análise dos mecanismos do inconsciente, pela investigação do que se entende por corpo e da sua relação com o conceito de coração. Estuda‑se a oposição entre espírito e coração, como formas de “legislação” contrárias entre si, e como se produz o seu apaziguamento.

_ Source: _Page Count 21 A historical sequence is said to be hyperfactual whenever it contains facts that have been proved to exist twice, that is, they exist under two alternative courses of events: the factual and the counterfactual. In such cases, we may verify whether multiple courses of action lead to the same outcome. Drawing upon an idea from Nelson Goodman, each section of this article highlights a different type of hyperfactual sequence: those resulting from the turbulence of historical (...) turning points; those resulting from long term historical sequences; and those resulting from competing courses of action. The final section conveys how hyperfactuals represent the resistance of the multiple layers of history to the formalism of subjunctive conditionals. (shrink)

In this paper the use of mathematics in economics will be discussed, by comparing two approaches to mathematics, a Cartesian approach, and a Newtonian approach. I will argue that while mainstream economics is underpinned by a Cartesian approach which led to a divorce between mathematics and reality, the contributions of key authors of the Cambridge tradition, like Marshall, Keynes and Sraffa, are characterised by a Newtonian approach to mathematics, where mathematics is aimed at a study of reality. Marshall was influenced (...) by the Newtonian approach that still characterised many aspects of the Cambridge Mathematical Tripos, where the emphasis was on geometrical and mechanical examples rather than on symbolic (Cartesian) mathematics. Keynes, who criticised (Cartesian) symbolic mathematics, was indeed an admirer of Newton and of his method. Sraffa's mathematical constructions are also in line with the Newtonian approach where arithmetic and geometry were strictly separated, since Sraffa's mathematical constructions typically use arithmetic without engaging in the mixture between geometry and arithmetic that occurs in the Cartesian approach.

Background: Psychedelics are known for their powerful mental effects due to the activation of 5HT-2A receptors in the brain. During the 1950s and 1960s, research was conducted on these molecules until their criminalization. However, their clinical investigation as therapeutic tools for psychiatric disorders has revived the deontological ethics surrounding this subject. Questions arise as research on their therapeutic outcome becomes a reality. We aim to explore deontological ethics to understand the implications of psychedelics for the clinician, patient, and society. Results: (...) A total of 42 articles were considered for this review. Methods: A methodological search of psychedelic studies from 2017 to 2022 was conducted in PubMed, Scopus, EBSCOhost, and ScienceDirect to address the deontological ethics of clinical psychedelic use. Conclusion: Psychedelics need to be culturally contextualized, epistemic harm minimized and represented to ensure informed consent. Open data and commissions are needed to ensure safe and equal distribution. (shrink)

Warming up prior to competition is a widely accepted strategy to increase players’ readiness and achieve high performances. However, pre-match routines are commonly based on empirical knowledge and strongly influenced by models emerging from elite team practices. The aim of the present study was to identify and analyze current pre-match warm-up practices in elite futsal. Forty-three elite players were analyzed during their pre-match warm-up routines during the Portuguese Futsal Cup Final 8. Warm-up tasks were classified according to duration, type of (...) activity, sequence, and structure. External load variables included the total distance covered, total distance covered per minute, running distance per minute, sprinting distance per minute, number of accelerations per minute, and number of decelerations per minute. Results highlighted that warm-up routines lasted for 27.5 ± 9.2 min and included nine major different tasks. Open-skill activities were prioritized by coaches; competitive and non-competitive futsal-specific tasks were included in 90% of the total warm-up routines, with higher focus on non-competitive tasks. The intensity progressively increased during warm-ups, mainly because of the higher number of accelerations and decelerations per minute. Pre-match warm-up routines strongly endorse futsal-specific and representative tasks in order to establish pre-match settings able to prepare players for the upcoming game. When designing pre-match warm-up routines, coaches should be aware that duration, sequence, and type of tasks may affect players’ acute performance and readiness. (shrink)

Hume argued that inductive inferences do not have rational justification. My aim is to reject Hume's argument. The discussion is partly motivated by an analogy with Carroll's Paradox, which concerns deductive inferences. A first radically externalist reply to Hume is that justified inductive inferences do not require the subject to know that nature is uniform, though the uniformity of nature is necessary condition for having the justification. But then the subject does not have reasons for believing what she believes. I (...) defend a moderate externalist account that seeks to partly accommodate that objection to the radical externalist proposal. It is based on an extension of Peacocke's theory of concepts: possession conditions for predicative concepts standing for natural properties include dispositions to project them to new cases in accordance with inductive inferential patterns.
