The article, as part of a broader reflection on the criticism of the right to development and its impact on the modes of legal and political subjectivation of children and adolescents, questions the child's condition as a subject without speech, or a speech conditioned to criteria of maturation, dictated by the adult referential, in a field, moreover, limited to what is said to be pertinent to their manifestation. Guided by the thought of exteriority, we return to the Foucauldian debate on (...) the relation between truth and justice, in light of the monstrous unspeakability of legal and judicial practices and the ubuesco of state power. We will analyze, through the contributions of classic cynicism, supported by Foucault, and Sloterdijk, Nieheus-Pröbsting, the resistant practices - beyond language – available to children and adolescents, and rethink these power struggles in the context of human rights and the possibility of justice, through the thought of Derrida, Rancière, Butler and Foucault. Our text will develop along the following axes of analysis: 1. Contextualizing the Foucaultian debate on truth and justice and the place of the “sayable”; 2. Considering the sayability at the heart of law, childhood and monstrosity; 3. Framing the struggle between ubuesco power and cynic resistance, and 4. Speculating on our notions of “child” and the possibility of justice. (shrink)

The negative impact of the COVID-19 pandemic on individuals’ psychosocial functioning was widely attested during the last year. However, the extent to which individual differences are associated with adaptive and maladaptive outcomes during quarantine in Italy remains largely unexplored. Using a person-oriented approach, the present study explored the association of personality profiles, based on three broad individual dispositions and two self-efficacy beliefs in the emotional area, with adaptive and maladaptive outcomes during the first Italian lockdown. In doing so, we focused (...) also on how different age groups differently faced the pandemic. The study was conducted through an online survey from May to June 2020 and included 1341 participants living in Italy, divided into two groups: 737 young adults aged 18–35 and 604 adults aged 36–60 years old. Latent Profile Analysis identified three personality profiles: resilient, vulnerable, and moderate. A subsequent path analysis model showed that the resilient profile was positively associated with prosocial behavior as an indicator of adaptive outcome, and negatively associated with three maladaptive outcomes: interpersonal aggression, depressive symptoms, and anxiety problems. Contrarily, the vulnerable profile resulted negatively associated with prosocial behavior and positively associated with the three maladaptive outcomes. Finally, regarding age group differences, young adults belonging to the vulnerable profile showed a greater association especially with interpersonal aggression, depression, and anxiety problems, as compared to adults belonging to the same profile. Overall, the results of the present study highlighted the importance to analyze individual functioning during an isolation period by using a person-oriented approach. Findings evidenced the existence of three different profiles and subsequent path analysis revealed, especially for the vulnerable profile and young adults, a greater maladaptive consequence of the quarantine. The practical implications will be discussed. (shrink)

This paper presents an intuitive explanation about why and how Rawlsian Theory of Justice (Rawls in A theory of justice, Harvard University Press, Harvard, 1971) provides the foundations to a solution for algorithmic bias. The contribution of the paper is to discuss and show why Rawlsian ideas in their original form (e.g. the veil of ignorance, original position, and allowing inequalities that serve the worst-off) are relevant to operationalize fairness for algorithmic decision making. The paper also explains how this leads (...) to a specific MinMaxfairness solution, which addresses the basic challenges of algorithmic justice. We combine substantive elements of Rawlsian perspective with an intuitive explanation in order to provide accessible and practical insights. The goal is to propose and motivate why and how the MinMaxfairness solution derived from Rawlsian principles overcomes some of the current challenges for algorithmic bias and highlight the benefits provided when compared to other approaches. The paper presents and discusses the solution by building a bridge between the qualitative theoretical aspects and the quantitative technical approach. (shrink)

Evidence is accumulating that individual and environmental factors in childhood and adolescence should be considered when investigating adult health and aging-related processes. The data required for this is gathered by comprehensive long-term longitudinal studies. This article describes the protocol of the Zurich Longitudinal Studies, a set of three comprehensive cohort studies on child growth, health, and development that are currently expanding into adulthood. Between 1954 and 1961, 445 healthy infants were enrolled in the first ZLS cohort. Their physical, motor, cognitive, (...) and social development and their environment were assessed comprehensively across childhood, adolescence, and into young adulthood. In the 1970s, two further cohorts were added to the ZLS and assessed with largely matched study protocols: Between 1974 and 1979, the second ZLS cohort included 265 infants, and between 1970 and 2002, the third ZLS cohort included 327 children of participants of the first ZLS cohort. Since 2019, the participants of the three ZLS cohorts have been traced and invited to participate in a first wave of assessments in adulthood to investigate their current health and development. This article describes the ZLS study protocol and discusses opportunities, methodological and conceptual challenges, and limitations arising from a long-term longitudinal cohort recruited from a study about development in early life. In the future, the ZLS will provide data to investigate childhood antecedents of adult health outcomes and, ultimately, will help respond to the frequent call of scientists to shift the focus of aging research into the first decades of life and, thus, to take a lifespan perspective on aging.

The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its corollary process theory, active inference; and (2) if so, to assess which philosophical stance - in relation to the ontological and epistemological status of representations - is most appropriate. We focus on non-realist (deflationary and fictionalist-instrumentalist) approaches. We consider a deflationary account of mental representation, according to which the explanatorily relevant contents of neural (...) representations are mathematical, rather than cognitive, and a fictionalist or instrumentalist account, according to which representations are scientifically useful fictions that serve explanatory (and other) aims. After reviewing the free-energy principle and active inference, we argue that the model of adaptive phenotypes under the free-energy principle can be used to furnish a formal semantics, enabling us to assign semantic content to specific phenotypic states (the internal states of a Markovian system that exists far from equilibrium). We propose a modified fictionalist account: an organism-centered fictionalism or instrumentalism. We argue that, under the free-energy principle, pursuing even a deflationary account of the content of neural representations licenses the appeal to the kind of semantic content involved in the aboutness or intentionality of cognitive systems; our position is thus coherent with, but rests on distinct assumptions from, the realist position. We argue that the free-energy principle thereby explains the aboutness or intentionality in living systems and hence their capacity to parse their sensory stream using an ontology or set of semantic factors.

Italian Sounding—i. e., the Italian appearance of a product or service brand irrespective of its country of origin—represents a global market phenomenon affecting a wide range of economic sectors, particularly the agro-food sector. Although its economic impact has been repeatedly stressed from different points of view, systematic scientific knowledge regarding its social–psychological bases is lacking. Three studies carried out in three different countries address this literature gap. Different consumer groups are targeted regarding major product categories pre-selected categories, which are the (...) major Italian food goods within the specific country according to piloting. In each study, the main independent variable has been manipulated by presenting real product images, whose “Italianness” degree is effectively manipulated by the main study variable across three or four levels. Main hypotheses are tested via a survey with the specific product images administered to samples in Italy, China, and the USA. Across the three studies, results show that Made in Italy products, compared to the other ones, are advantaged in terms of the main dependent variables: reputation profile, general reputation, attitude, and willingness to pay. Moreover, Italian Sounding products are endowed with corresponding significant advantages when compared to the Generic Foreign by non-Italian samples. Results reveal the specific social–psychological profile of Italian Sounding products in terms of either weaknesses or strengths when compared to both Made in Italy products and Generic Foreign ones, differently in the eyes of Italian and non-Italian consumers across different countries. Finally, consistently across the three studies, the extent to which a food product is perceived to be Italian increases consumers' WTP for that product, and this effect is consistently mediated by the product's reputation.

Platelets have important hemostatic functions in repairing blood vessels upon tissue injury. Cytokines, growth factors, and metabolites stored in platelet α‐granules and dense granules are released upon platelet activation and clotting. Emerging evidence indicates that such platelet‐derived signaling factors are instrumental in guiding tissue regeneration. Here, we discuss the important roles of platelet‐secreted signaling factors in skeletal muscle regeneration. Chemokines secreted by platelets in the early phase after injury are needed to recruit neutrophils to injured muscles, and impeding this early (...) step of muscle regeneration exacerbates inflammation at later stages, compromises neo‐angiogenesis and the growth of newly formed myofibers, and reduces post‐injury muscle force production. Platelets also contribute to the recruitment of pro‐regenerative stromal cells from the adipose tissue, and the platelet releasate may also regulate the metabolism and proliferation of muscle satellite cells, which sustain myogenesis. Therefore, harnessing the signaling functions of platelets and the platelet secretome may provide new avenues for promoting skeletal muscle regeneration in health and disease. (shrink)

The purpose of this scoping review is to investigate the value of creative arts therapies in healthy older adults. This article aims to shed light on current knowledge concerning the effectiveness of art therapies for the prevention of common age-related conditions using the definition of art therapy provided by the American Art Therapy Association, as well as Cohen’s conceptual framework for the psychological conceptualization of the relationship between the arts and health in later life. The objective is to carefully capture (...) subthreshold situations of distress, which are often not taken into account and primarily involve psychological aspects that are crucial in the multidimensional perspective of healthy aging. Twelve articles were selected and examined following an initial electronic search on 3 databases. A thematic analysis of the results identified four major themes: improving cognitive performance and proprioception; enhancing self-identity and meaningful life; reducing feelings of loneliness and depressive symptoms; and the importance of socialization. All these aspects constitute the basis for preventing psychological distress and enhancing mental well-being for healthy aging. (shrink)

Es conocido el efecto de espectacularización derivado del proceso de colonialización-mundialización de la cultura: una vez que la actividad local ingresa en la economía política mundial de la cultura, cada acontecimiento se vuelve espectáculo , con su doble aspecto de “estrellato” y “museificación”. En efecto, ante la multiplicación de modos de vida que circulan en las redes telecomunicacionales, Estados e industrias culturales buscan por un lado preservar formas sociales y culturales que se consideran en peligro y, por otro, difundir y (...) explicar esas mismas formas. En este marco, el museo ha aparecido últimamente como uno de los dispositivos privilegiados para afrontar este doble propósito. Analizaré aquí un museo que se resiste a petrificar aquello que pretende cuidar, así como a extraer el núcleo de su razón de ser únicamente de las motivaciones económicas asociadas a la inversión en cultura. Me refiero al Museo-Taller Ferrowhite, ubicado en Ingeniero White, provincia de Buenos Aires. Propongo que se trata de un museo que se sabe un artefacto cultural hiper complejo, capaz de identificar la tensión que él mismo encarna, como institución estatal, al intentar contar la (su) historia y proponer un sentido para el rescate de esa historia en el presente.

Resenha do livro Filosofia da Ancestralidade de Eduardo David de Oliveira.

Synaptophysin (Syp) was the first synaptic vesicle (SV) protein to be cloned. Since its discovery in 1985, it has been used by us and by many laboratories around the world as an invaluable marker to study the distribution of synapses in the brain and to uncover the basic features of the life cycle of SVs. Although single gene ablation of Syp does not lead to an overt phenotype, a large body of experimental data both in vitro and in vivo indicate (...) that Syp (alone or in association with homologous proteins) is involved in multiple, important aspects of SV exo‐endocytosis, including regulation of SNARE assembly into the fusion core complex, formation of the fusion pore initiating neurotransmitter release, activation of SV endocytosis and SV biogenesis. In this article, we summarise the main results of the studies on Syp carried out by our and other laboratories, and explain why we believe that Syp plays a major role in SV trafficking.

Based on the theoretical reconstruction of neglected post-WWI writings and political action of W. E. B. Du Bois, this volume offers a normative account of transnational cosmopolitanism. Pointing out the limitations of Kant's cosmopolitanism through a novel contextual account of Perpetual Peace, Transnational Cosmopolitanism shows how these limits remain in neo-Kantian scholarship. Inés Valdez's framework overcomes these limitations in a methodologically unique way, taking Du Bois's writings and his coalitional political action both as text that should inform our theorization and (...) normative insights. The cosmopolitanism proposed in this work is an original contribution that questions the contemporary currency of Kant's canonical approach and enlists overlooked resources to radicalize, democratize, and transnationalize cosmopolitanism.

This paper is the result of my participation in a discussion event of Problema. Anuario de filosofía y teoría del derecho entitled “The Construction of Precedent in Civil Law: Debates, Concepts and Challenges”. Several colleagues with a vast knowledge on the subject of judicial precedent participated in this seminar, which also delved into the widely debated aspects of judicial precedent focused on the case of Chile. The entire discussion aimed at proposing solutions, as well as shedding some light on some (...) of its important aspects.Starting from such transcendental concepts as, rationality and argumentative use, it is possible to find certain problems arising from the improper use of the above concepts, which in turn leads us to stare decisis, a term that if used incorrectly may result in an act against the internal independence of judges.

El presente trabajo es el resultado de mi participación en el evento de discusión de la revista Problema. Anuario de Filosofía y Teoría del Derecho, que llevó por nombre “La construcción del precedente en el Civil Law: debates, conceptos y desafíos”, en el cual participaron varios colegas con un amplio conocimiento en el tema del precedente judicial; de igual forma, ahonda en los temas de mayor debate dentro de lo referente al precedente judicial, enfocado al caso chileno. Todo ello, con (...) la finalidad de proponer algunas soluciones al respecto, así como dilucidar ciertos aspectos importantes dentro del precedente. Partiendo de conceptos tan trascendentes como la prescriptibilidad, la racionalidad y el uso argumentativo, se logra llegar a ciertas problemáticas provocadas por el mal uso de los conceptos previamente mencionados, que a su vez nos conduce al stare decisis, término que mal utilizado puede resultar en un acto contrario a la independencia interna de la cual gozan los jueces.

In this paper we propose a pragmatic approach to the evolution of language based on analysis of a particular element of human communication: discourse coherence. We show that coherence is essential for effective communication. Through analysis of a collection of neuropsychological and neurolinguistic studies, we maintain that the proper functioning of executive processes responsible for planning and executing actions plays a key role in the construction of coherent discourses. Studies that tested the discursive and conversational abilities of bonobos have showed (...) that apes are unable to construct a flow of discourse governed by coherence, and therefore, apes’ conversational interactions are quite different from those of humans. We then propose that the emergence of coherence in communication occurred after the split between great apes’ and humans’ lines of descendants and that this emergence might have been the result of a specific gradual development in the course of hominin evolution of the executive functions.

High blood pressure (HBP) is a multifactorial clinical condition characterized by high and sustained levels of blood pressure (BP), and the presence of elevated BP in childhood is predictor of hypertension in adult life. Studies have shown a positive correlation between sodium chloride ingested in the diet and blood pressure values. This study aims to evaluate the consumption of added salt before and after awareness of risk, by high school students. This occurred for three days in the refectory, where students (...) received illustrative brochure with information about sodium intake; exhibition of a poster illustrating foods with their respective equivalent amount of sodium and sodium chloride, exemplifying the maximum recommended amount of consumption per day. For five days, before and after gaining awareness, it the amount of consumption of sachets of salt was accounted. Statistical analyzes were performed by Student's Test, with a confidence interval of 95%. During the study period were served on average 128.3 meals. Before the awareness of sodium consumption of risks, of 820mg and 330mg sodium salt was consumed an average per individual, and thereafter, 640mg and 260mg, respectively (p=0,043). Simple Nutrition Education Strategies in short term were effective for improving the consumption of added salt in adolescents. (shrink)

Trata-se de investigar os tipos de tropas, tal como apresentados por Maquiavel, procurando compreender as características que destacam as tropas próprias. Feito isso, assumiremos o debate entre o que é público e o que é particular, tal como posto na Arte da Guerra, relacionando-o ao tema da guerra. Tal objetivo diz respeito à investigação anunciada por Maquiavel e que relaciona a vida civil à vida militar. Procurar-se-á mostrar a perspectiva do autor sobre o uso público da guerra tanto quanto as (...) consequências desastrosas de seu uso particular. Pretende-se, em tal percurso, evidenciar a guerra como ponto central do pensamento maquiaveliano, diretamente relacionada aos fundamentos da política, assim como o interesse de Maquiavel em pensar os problemas de seu tempo e abordá-los por uma perspectiva filosófica. A pesquisa se restringe a investigar o tema a partir do Príncipe, dos Discursos sobre a Primeira Década de Tito Lívio e da Arte da Guerra. (shrink)

Entendemos os eventuais problemas em discutir subjetividades a partir dos escritos de dois pensadores tão diferentes como Foucault e Winnicott, mas nesse estudo, o objetivo é fornecer um possível contraponto _winnicottiano_ para as análises realizadas por Foucault a respeito da subjetividade na racionalidade neoliberal. Nossa proposta é pensar a constituição da subjetividade na racionalidade política neoliberal, que conforme verificamos, constrói indivíduos psiquicamente voltados para certo individualismo em detrimento da ética e da alteridade. Após uma discussão sobre a dinâmica da formação (...) do capital humano, conforme apresentado por Foucault, e da apresentação das noções fundamentais acerca dessa constituição específica da subjetividade, realizamos um contraponto apresentando os pontos fundamentais da teoria do amadurecimento de Winnicott para pensar a respeito de possíveis consequências psíquicas que a racionalidade neoliberal, produtora de sujeitos voltados para a competição, impõe a essas estruturas subjetivas.

Parmenides and Melissus employ different deductive styles for their different kinds of argumentation. The former’s poem flows in an interesting sequence of passages: contents foreword, methodological premises, krisis, conclusions and corollaries. The latter, however, organizes an extensive process of deduction to show the characteristics of what is. In both cases, the strength of their argument rests on their deductive form, on the syntactical level of their texts: the formal structure of their reasonings help to identify the features and logical intersections (...) of their thoughts. On the one hand, Parmenides uses modal reasoning, enforcing the employment of the principle of the excluded middle. On the other hand, Melissus radicalizes the use of modal reasoning and employs counterfactual statements in order to develop his doctrine of what is. Despite their differences, both deserve a place in the Stone Age of logic and theory of argumentation due to their common ambition to demonstrate what is. (shrink)

In recent years, Reichenbach's 1920 conception of the principles of coordination has attracted increased attention after Michael Friedman's attempt to revive Reichenbach's idea of a "relativized a priori". This paper follows the origin and development of this idea in the framework of Reichenbach's distinction between the axioms of coordination and the axioms of connection. It suggests a further differentiation among the coordinating axioms and accordingly proposes a different account of Reichenbach's "relativized a priori".

This edited book deepens the engagement between 21st century philosophy of mind and the emerging technologies which are transforming our environment. Many new technologies appear to have important implications for the human mind, the nature of our cognition, our sense of identity and even perhaps what we think human beings are. They prompt questions such as: Would an uploaded mind be 'me'? Does our reliance on smart phones, or wearable gadgets enhance or diminish the human mind? and: How does our (...) deep reliance upon ambient artificial intelligence change the shape of the human mind? Readers will discover the best philosophical analysis of what current and near future 21st technology means for the metaphysics of mind. Important questions are addressed on matters relating to the extended mind and the distributed self. Expert authors explore the role that the ubiquitous smart phone might have in creating new forms of self-knowledge. They consider machine consciousness, brain enhancement and smart ambient technology, and what they can tell us about phenomenal consciousness. While ideas of artificial general intelligence, cognitive enhancements and the smart environment are widely commented on, serious analysis of their philosophical implications is only getting started. These contributions from top scholars are therefore very timely, and are of particular relevance to students and scholars of the philosophy of mind, philosophy of technology, computer science and psychology.

Admiration and adoration have been considered as emotions with the power to change people, yet our knowledge of the specific nature and function of these emotions is quite limited. From an interdisciplinary perspective, we present a prototype approach to admiration and what has variously been labelled adoration, worship, or reverence. Both admiration and adoration contribute to the formation of personal and collective ideals, values, and identities, but their workings differ. We offer a detailed theoretical account of commonalities and differences in (...) the appraisal patterns and action tendencies associated with the two emotions. This analysis reveals that admiration motivates the internalisation and emulation of ideals embodied by an outstanding role model. Adoration motivates adherence to the teachings and expectations of a meaning maker and benefactor perceived as superhuman or sacred. Thus, the primary function of admiration is to promote individual learning and change, whereas adoration primarily serves to bind communities together. (shrink)

This highly multidisciplinary collection discusses an increasingly important topic among scholars in science and technology studies: objectivity in science. It features eleven essays on scientific objectivity from a variety of perspectives, including philosophy of science, history of science, and feminist philosophy. Topics addressed in the book include the nature and value of scientific objectivity, the history of objectivity, and objectivity in scientific journals and communities. Taken individually, the essays supply new methodological tools for theorizing what is valuable in the pursuit (...) of objective knowledge and for investigating its history. The essays offer many starting points, while suggesting new avenues of research. Taken collectively, the essays exemplify the very virtues of objectivity that they theorize—in reading them together, the reader can sense various anxieties about the dangerously subjective in our age and locate commonalities of concern as well as differences of approach. As a result, the volume offers an expansive vision of a research community seeking a communal understanding of its own methods and its own epistemic anxieties, struggling to enunciate the key problems of knowledge of our time and offer insight into how to overcome them. -/- (Contributors: Alex Csiszar, Scott Edgar, Peter Galison, Ian Hacking, Sandra Harding, Moira Howes, Paolo Savoia, Judy Segal, Joan Steigerwald, and Alison Wylie).

One of the criteria to a strong principle in natural sciences is simplicity. This paper claims that the Free Energy Principle (FEP), by virtue of unifying particles with mind, is the simplest. Motivated by Hilbert’s 24th problem of simplicity, the argument is made that the FEP takes a seemingly mathematical complex domain and reduces it to something simple. More specifically, it is attempted to show that every ‘thing’, from particles to mind, can be partitioned into systemic states by virtue of (...) self-organising symmetry break, i.e. self-entropy in terms of the balance between risk and ambiguity to achieve epistemic gain. By virtue of its explanatory reach, the FEP becomes the simplest principle under quantum, statistical and classical mechanics conditions. (shrink)

This aim of this paper is two-fold: it critically analyses and rejects accounts blending active inference as theory of mind and enactivism; and it advances an enactivist-dynamic understanding of social cognition that is compatible with active inference. While some social cognition theories seemingly take an enactive perspective on social cognition, they explain it as the attribution of mental states to other people, by assuming representational structures, in line with the classic Theory of Mind. Holding both enactivism and ToM, we argue, (...) entails contradiction and confusion due to two ToM assumptions widely known to be rejected by enactivism: that social cognition reduces to mental representation and social cognition is a hardwired contentful ‘toolkit’ or ‘starter pack’ that fuels the model-like theorising supposed in. The paper offers a positive alternative, one that avoids contradictions or confusion. After rejecting ToM-inspired theories of social cognition and clarifying the profile of social cognition under enactivism, that is without assumptions and, the last section advances an enactivist-dynamic model of cognition as dynamic, real-time, fluid, contextual social action, where we use the formalisms of dynamical systems theory to explain the origins of socio-cognitive novelty in developmental change and active inference as a tool to demonstrate social understanding as generalised synchronisation.

The organization of the Herodotian narrative is based overall in the characterization of the despotism, however this can only mean something in Herodotus‟ work if opposed to the Greek ways of political organization and mainly in relation to democracy. However, the fact that the barbarians‟ despotism takes higher evidence in the work is enough to make the theme of tyranny dominate over the poliada organization? Could not we assume that the distinction of tyranny would not be only one way to (...) show the Greeks their own particularity? In this case, the exotic one, marvelous and the admirable one would lie in the fact that the Greeks organized a completely singular way of political organization, stranger to all the other known peoples.

Pretende-se investigar, a partir especialmente dos primeiros capítulos dos Discursos sobre a Primeira Década de Tito Lívio, de Maquiavel, a confluência e divergência de aspectos tradicionais sobre a constituição de Roma em sua fase republicana.
