With respect to De Dreu and Gross's article, we comment on the psychological functions for attack and defense, focusing on associations between individual differences in psychopathic personality traits and the behavioral patterns observed in attack-defense conflicts. We highlight the dimensional nature of psychopathy and formulate hypothetical associations between distinct traits, their different behavioral outcomes, and associated brain mechanisms.

Nos onze capítulos que compõem o presente volume, encontramos assim um mapa conceptual da Filosofia que cobre não só as suas disciplinas principais, mas também muitas das suas áreas mais especializadas. Cada capítulo é autónomo, pode ser compreendido sem se recorrer a outros capítulos. O desafio que todos os autores enfrentaram foi o de apresentar uma determinada disciplina filosófica com clareza, rigor e concisão – três características difíceis de conciliar, sobretudo quando se aspira ainda a uma grande abrangência temática. No final de cada capítulo, o leitor poderá encontrar informação bibliográfica actualizada e apropriada para aprofundar o seu estudo. (shrink)

Até o início da idade moderna,Deus ocupava o centro do universo.Os humanistas da renascença elaboraram uma nova imagem do mundo,cujo senhor era o homem.A natureza foi devassada e 'desencantada':uma nova aliança substituiu a antiga.Parece que se materializaram os 'não-lugares' de todas as utopias.Contudo,todas elas padeciam de grave doença:não conseguiam discernir possibilidades reais de impossibilidades.

RESUMO: Interrogando-se sobre o lugar da filosofia de Theodor W. Adorno no âmbito do pensamento crítico contemporâneo, o presente artigo procura dar conta dos revezes da recepção político-filosófica da dialéctica negativa e discutir a sua relevância actual. Defender-se-á que a politização do pensamento adorniano é possível, muito embora as suas valências críticas não se restrinjam a essa possibilidade. Hoje, a dialéctica negativa funcionaria também como antídoto contra os atalhos tomados pelas correntes "voluntarista", "messiânica" e "ontológica" da filosofia, à entrada do (...) século XXI. Contudo, atendendo a que a relação entre teoria e prática é complexa em Adorno, a sua relevância actual ressaltaria em relação com as reacções críticas que o movimento do "realismo especulativo" tem suscitado. Em diálogo com alguns dos seus interlocutores, sugere-se que o desenvolvimento de uma "dialéctica constelar" depende da introdução de um elemento destotalizador no seio do diagnóstico radical - a um só tempo materialista e transcendental - da dialéctica negativa. ABSTRACT: Questioning the place of Theodor W. Adorno's philosophy within contemporary critical thought, this article attempts to account for the politico-philosophical reception of Adorno's negative dialectics and to discuss its present-day relevance. I argue that it is possible to politicize Adorno's work, although its critical valences go far beyond this possibility. Today, negative dialectics would provide an antidote against the shortcuts taken by 'voluntarist', 'messianic' and 'ontological' turns/trends in twenty-first-century philosophy. However, in view of the complexity of Adorno's appraisal of the interplay between theory and praxis, the current relevance of his thought gains plausibility by being linked with critical responses to 'speculative realism'. In dialogue with some of its interlocutors, I suggest that developing a 'constellative dialectics' depends on the introduction of a detotalizing element within the radical - at once materialistic and transcendental - diagnosis of negative dialectics.

O presente artigo tem como objetivo discutir o conceito de “literatura da mulher” a partir da leitura de duas importantes autoras do século XX: a filósofa francesa Simone de Beauvoir e a poeta, tradutora e crítica literária brasileira Ana Cristina Cesar. Ainda que distantes entre si, encontramos na produção intelectual de ambas as autoras diversas aproximações possíveis que nos permitem refletir a respeito das relações entre gênero e literatura a partir de noções como alteridade e representação, contribuindo para o debate (...) em torno deste conceito.Palavras-chave: Literatura. Gênero. Mulher. Simone de Beauvoir. Ana Cristina Cesar. AbstractThis paper intends to discuss the concept of “women’s literature” from the analysis of two important authors of the 20th century: the French philosopher Simone de Beauvoir and the Brazilian poet, translator and literary critic Ana Cristina Cesar. Although distant from each other, we find in the intellectual production of both authors several possible approximations that allow us to reflect on the relations between gender and literature based on notions such as alterity and representation, contributing to the debate surrounding this concept.Keywords: Literature.

O presente artigo consiste no registro de memórias de um diretor e de uma diretora que atuaram em escolas públicas de M inas Gerais, e na análise de suas narrativas. O objetivo foi captar suas representações sobre as práticas administrativas e pedagógicas rememoradas dos anos de exercício profissional. Com a metodologia da história oral, nossa investigação buscou construir uma interpretação a respeito de atitudes, posturas e práticas enraizadas nos rituais da escola contemporânea. Pudemos observar que no período estudado havia uma (...) política extremamente centralizada, cujas diretrizes eram difundidas pelos órgãos centrais da administração burocrática. O trabalho de gestão das unidades escolares era pautado, principalmente, pelo controle do cumprimento das normas estabelecidas pela política pública de educação. (shrink)

The importance of an author can be evaluated by the extent to which his theoretical contribution transforms a certain area of knowledge: major researchers create new vistas. This certainly applies to Lev Vygotsky (1896–1934), one of the most brilliant authors of contemporary psychology. His work, owing to its originality, is of epistemological interest to several areas of knowledge. In fact, Vygotsky was at the center of a historical time of change in twentieth-century Russia, in which Mikhail Bakhtin, Roman Jakobson, Serguei (...) Eisenstein, Alexander Luria, and Yuri Lotman took part. Their theoretical proposals had repercussions in several areas of knowledge: in literature, semiotics, film, and .. (shrink)

A ambiguidade do humor torna-o capaz de desvendar a verdade para lá da peta, do ópio, do fingimento, da falsidade – cada um destes sinónimos de mentira está presente, com subtis gradações, nos periódicos de José Daniel Rodrigues da Costa. O próprio conceito de mentira suscita reflexão e é questionado na sua relação com a verdade: “Com toda a certeza, se não for mentira.” O exagero das petas com que “tempera” as verdades chama a atenção dos leitores para a “verdade (...) encoberta” sob as convenções das práticas sociais, numa dialéctica do ser com o dever ser, do moral com o amoral, na fronteira entre o lícito e o ilícito nas últimas décadas do Estado absolutista e no dealbar do liberalismo. O estudo do humor, dos seus limites e do seu lugar nos periódicos na viragem do século XVIII para o XIX é uma das muitas formas da história das ideias. (shrink)

Hipólito da Costa (1774-1823) foi o redactor do primeiro periódico liberal de língua portugue­sa, o Correio Braziliense, e é considerado o patriarca do jornalismo brasileiro. Exilado em Lon­dres, desenvolveu no Correio um corpus doutrinal que culminou num Projecto de Constituição para o Brasil, tributário dos valores do modelo constitucional inglês. Anti-absolutista, anti-es­clavagista e anti-democrático, o seu liberalismo tem a marca do gradualismo como método pre­ferencial de evolução política e social.

The evolution and biodiversity of ageing have long fascinated scientists and the public alike. While mammals, including long‐lived species such as humans, show a marked ageing process, some species of reptiles and amphibians exhibit very slow and even the absence of ageing phenotypes. How can reptiles and other vertebrates age slower than mammals? Herein, I propose that evolving during the rule of the dinosaurs left a lasting legacy in mammals. For over 100 million years when dinosaurs were the dominant predators, (...) mammals were generally small, nocturnal, and short‐lived. My hypothesis is that such a long evolutionary pressure on early mammals for rapid reproduction led to the loss or inactivation of genes and pathways associated with long life. I call this the ‘longevity bottleneck hypothesis’, which is further supported by the absence in mammals of regenerative traits. Although mammals, such as humans, can evolve long lifespans, they do so under constraints dating to the dinosaur era. (shrink)

Despite recent progress in the identification of genes that regulate longevity, aging remains a mysterious process. One influential hypothesis is the idea that the potential for cell division and replacement are important factors in aging. In this work, we review and discuss this perspective in the context of interventions in mammals that appear to accelerate or retard aging. Rather than focus on molecular mechanisms, we interpret results from an integrative biology perspective of how gene products affect cellular functions, which in (...) turn impact on tissues and organisms. We review evidence suggesting that mutations that give rise to features resembling premature aging tend to be associated with cellular phenotypes such as increased apoptosis or premature replicative senescence. In contrast, many interventions in mice that extend lifespan and might delay aging, including caloric restriction, tend to either hinder apoptosis or result in smaller animals and thus may be the product of fewer cell divisions. Therefore, it appears plausible that changes in the number of times that cells, and particularly stem cells, divide during an organism's lifespan influence longevity and aging. We discuss possible mechanisms related to this hypothesis and propose experimental paradigms. BioEssays 30:567–578, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

Neste artigo, buscaremos refletir sobre como Hannah Arendt concebe um certo tipo de educação ao mesmo tempo _conservadora_ e _revolucionária_. Este será, assim como a indicação de que pensar sobre a questão educacional das crianças e jovens diz respeito a uma crise mais geral na modernidade, um ponto de tensionamento rumo à hipótese segundo a qual é possível refletir sobre como inserir os imigrantes, refugiados ou apátridas em um local ao qual se dirigiram e que lhes é estranho. Para tanto, (...) o fio condutor desta argumentação será o conceito de natalidade, pois consideramos ser a partir dele que Arendt evoca a radicalidade da qual todos os seres humanos são portadores, isto é, a potencialidade de começar algo novo. Assim, articulam-se os tensionamentos entre conservar um mundo que é precedente aos que lhe são recém-chegados, tanto as crianças como os migrantes, ao mesmo tempo em que estes adicionam algo de si mesmo neste mundo para os que ainda estão por vir.

In this paper, I intend to explore the 16th century Italian work entitled Divisione della filosofia (1895) by the writer Benedetto Varchi, by reflecting on concepts raised and discussed throughout the history of philosophy, such as art and science, while making a thorough analysis of the text and the conceptions exposed by the historian. From a historical-philosophical point of view, I intend to investigate a varchian corpus from the Renaissance period, thus, I examine the statements and inferences of the Florentine (...) writer, in order to make explicit his vision concerning the division and hierarchization of the areas of theoretical and practical knowledge of Philosophy. I then conclude how the classification that summarizes more than two thousand years of notions coming from Greek, medieval and renaissance philosophies could help in the formulation of the functions of knowledge and how they relate to the practical life of individuals in the Renaissance period.

O presente artigo explora as manifestações básicas do conceito de justiça em Jr. 1-25, atendendo à interacção entre justiça social, realeza e profetismo no contexto do Próximo Oriente antigo. É contextualmente analisado o principal léxico pertencente aos campos semânticos da justiça e da injustiça, em sentido estrito, incluindo as categorias sociais directamente envolvidas (estrangeiro, viúva, órfão, pobre, oprimido, necessitado, etc.). Nos termos do iaveísmo hierosolimita e da ideologia régia davídica, Jeremias desenvolve um discurso de denúncia social relativamente genérico sobretudo direccionado (...) para a realeza, exortando-a a cumprir o seu papel de garante do funcionamento e implementação da justiça na sociedade. É contra Joaquim que a polémica jeremiana atinge o seu auge, criando uma imagem de anti-rei que inverte totalmente o paradigma de realeza humana e divina exemplarmente retratada nos salmos reais. O direito consuetudinário do Código da Aliança, e sobretudo a tradição profética (Amós, Miqueias e Isaías) e sapiencial (Salmos e Provérbios), e não o Deuteronómio, devem fornecer o quadro interpretativo preferencial para o conceito de justiça social em Jeremias.

A investigação de um domínio amplo da realidade, como a evolução dosseres vivos, pode dar origem a diferentes “teorias”, cada uma consoantecom uma particular perspectiva que se considere. Para que se proceda auma análise detalhada dos pressupostos e conceitos que baseiam umadeterminada visão, o método axiomático parece ser a melhor das opções.Neste artigo, são discutidas algumas teorias da biologia evolutiva de umponto de vista axiomático, mostrando-se de que forma se pode apresentarum “predicado de Suppes” para a teoria sintética da evolução, (...) comodetalhado em outro local . Estaformulação é utilizada, dentre outras coisas, para se discutir a noção deaptidão darwiniana, bem como para explorar as relações entre a teoriadarwiniana da seleção natural e a genética de populações.The investigation of a wide field of knowledge, as evolution of living beings,may originate different “theories”, each one acting as a particularperspective we have about the domain. In order to proceed a philosophicalanalysis of the underlying assumptions of a particular view, it seems thatthe use of the axiomatic method is still the better way. Here, we discuss some theories of evolutionary biology from an axiomatic point of view, bymeans of a Suppes predicate for the synthetic theory of evolution, alreadydetailed in MAGALHÃES and KRAUSE . This formulation is hereused, among other things, to deal with the concept of Darwinian fitness, soas to explore the relationships between Darwinian theory and populationgenetics. (shrink)

Neste trabalho apresentamos os resultados de uma pesquisa desenvolvida por uma aluna de graduação durante a realização de seu estágio docência. O objetivo da pesquisa foi investigar a relação entre trabalho e ensino de matemática em uma escola do campo na região sudeste do estado do Pará, na região norte do Brasil. A metodologia utilizada foi de inspiração etnográfica e os dados foram registrados no caderno de campo da pesquisadora. Também constitui material de análise as produções dos alunos e as (...) observações realizadas em sala de aula. Ao longo do texto apresentamos o contexto de realização da pesquisa, listando, de maneira breve, as principais características do curso de graduação no qual a pesquisadora está matriculada, bem como o contexto geográfico da comunidade onde está localizada a escola no qual a pesquisa foi realizada. Em seguida apresentamos nossa compreensão de duas noções centrais para nossa análise: conhecimento e trabalho. A primeira é tomada de um referencial teórico produzido no interior da Educação Matemática brasileira, conhecido como Modelo dos Campos Semânticos e a segunda é assumida em consonância com um referencial teórico marxista. Após o referencial teórico apresentamos a metodologia da pesquisa, destacando de modo geral as atividades que foram realizadas no estágio docência que se configurou como locus da produção dos dados da pesquisa. Nas análises, apresentamos as compreensões elaboradas pela pesquisadora a partir da articulação do referencial teórico com as atividades desenvolvidas durante o estágio. Colocamos em evidência que a compreensão de trabalho apresentada pelos alunos da escola investigada leva em consideração apenas o aspecto financeiro de algumas atividades realizadas por eles em seu dia a dia. Essa compreensão é colocada em contraste com a definição de trabalho apresentada pelos referenciais teóricos adotados. Por fim, tecemos algumas considerações sobre o uso de categorias tomadas da vida cotidiana nos processos de ensino e aprendizagem de Matemática. Apontamos que essa perspectiva teórica abre a possibilidade de uma ação didática que coloca em evidência a não centralidade da Matemática nos processos de produção de conhecimento, bem como viabiliza a utilização de outras categorias no processo de produção de conhecimento de modo não hierárquico em relação à ciência ocidental.

Neste trabalho apresentamos uma experiência de estágio realizada em uma escola indígena Kyikatêjê, na região norte do Brasil e analisamos aspectos dessa experiência a partir dos conceitos de autoridade e espaço comunicativo transcultural. Para tanto, descrevemos de modo breve o contexto no qual a pesquisa de estágio ocorreu, destacando os objetivos do estágio, o período de realização e os professores envolvidos. Nesse relato, situamos o ponto de interesse que motivou a escrita do presente trabalho. Indicado nosso objeto de estudos, apresentamos (...) duas seções teóricas que caracterizam a perspectiva com a qual trabalhamos. Na primeira, expomos o conceito de autoridade, entendida a partir do Modelo dos Campos Semânticos. Apresentamos como esse conceito está relacionado à justificação utilizada na produção de conhecimento. Ao fazer isso, afirmamos que nosso interesse se dirige aos aspectos epistemológicos da experiência realizada. Na sessão seguinte, apresentamos o conceito de espaço comunicativo transcultural, como sendo aquelas situações de interação onde duas ou mais culturas se encontram e que a alteridade do espaço constituído nesse encontro, possibilita o compartilhamento de legitimidades entre elas. Após apresentar os conceitos teóricos é apresentada a experiência de estágio de modo a colocar em evidência a relação entre o estagiário, os professores e os alunos e não os conteúdos trabalhos. Na última seção essa experiência de estágio é analisada à luz dos conceitos apresentados. Apontamos na conclusão que o comportamento dos alunos advém de legitimidades constituídas na cultura da qual fazem parte, mas esse comportamento não indica necessariamente uma abertura para o processo de aprendizagem. Apontamos, também, que a criação de um espaço comunicativo que mobiliza as legitimidades da cultura Kyikatêjê na aula de Matemática, privilegiando os modos de produzir conhecimento dessa cultura, oportunizou uma mudança no processo de produção de conhecimento dos alunos.

We explore Peirce’s pragmatic conception of sign action, as a distributed and emergent view of cognition and exemplify with the emergence of classical ballet. In our approach, semiosis is a temporally distributed process in which a regular tendency towards certain future outcomes emerges out of a history of sign actions. Semiosis self-organizes in time, in a process that continuously entails the production of more signs. Emergence is a ubiquitous condition in this process: the translation of signs into signs cannot be (...) inferred from the properties of the components of a semiotic triad alone, but has to take into account a complex interaction between a micro-semiotic and macro-semiotic level of description. This interaction can be understood as an interplay of potentialities and tendencies, or upward constitutive determinative relations and downward selective determinative relations. According to this view, emergence is a central defining condition of processes of meaning. Ballet is a sign in action. The emergence of classical ballet is a self-regulatory process, in which a system of different kinds of cognitive artifacts (musical, bodily/motor, spatial/architectonic) and agents obtained a stable semiotic relation throughout many phases of development between the 16th and the 19th Century. One case is the development of the verticality of dance in classical ballet as a semiotic relation connecting proscenium arch stages, dancing bodies, and audiences. This development is micro-semiotically determined by the spatial constraints of the proscenium arch stage, and macro-semiotically determined by a historical construction of the dancing body as a sign within a network of semiotic chains, such as the intersemiotic regulation of body of the dancer by principles coming from painting. This is not only the emergence of actual meaning, but also the emergence of an open-ended field of potential and general meanings, an autonomous tendency of development. To say that ballet, as sign action, emerges, is to say that cognitive artifacts such as dancer’s bodies, stages and audience’s point of view, musical compositions, costumes, all sorts of supporting institutions, etc, constitute a niche for sign action, interacting according to tendencies of development that didn’t exist before.

Journal Name: Semiotica Issue: Ahead of print.

The main purpose of this work is to provide a semiotic ontology for redescription of active cognitive externalism, recently developed by the paradigm 4E (embodied, embedded, enactive, extended cognition). In our approach, distributed cognitive systems (DCSs) are described as semiosis, signs in action. We explored the relationship between semiosis and cognition, as conceived by C. S. Peirce, in association with the notion of distributed cognitive system (DCS). We introduce Peircean externalist approach with an emphasis on the notion of temporal distribution (...) of semiosis, and describe DCSs, and their elements, as “sign in action”. To develop this argument, we describe an example of DCS -- verbal-musical improvisation of repente, repentismo, or viola singing. It is a phenomenon of verbal-musical improvisation that takes the form of a challenge in versified oral poetry. We describe the phenomenon as the embodiment of the formal structure of a cognitive task and an inferential process. This embodiment corresponds to a semiotization of the repente performances as DCSs. The temporally distributed tendency of repentismo organizes the DCS as a system that performs metasemiotic experiments on the action of signs. (shrink)

In the last 10 years, emotional intelligence has become a current issue of research in psychology, and there are indicators to consider that emotional intelligence should be analyzed to help the coach to behave effectively during competitions. According to Boardley’s (2018) revised model of coaching efficacy, coaches’ emotional intelligence is predictive of their efficacy beliefs, which, in turn, is predictive of coaching behavior. However, little is known about the mediating effects of coaching efficacy dimensions on the relationships between coach’s emotional (...) intelligence and reactive behaviors in competitive settings. Thus, the purpose of this study is to examine mediating effects of coaching efficacy dimensions on the relationship between emotional intelligence and coaches’ reactive behaviors during a game using a multimethod approach. Participants were 258 coaches of youth football players aged 9 to 17 years old. Observations in situ using Coaching Behavior Assessment System were carried on 258 football games during two seasons. At the end of each game, coaches completed the Wong and Law Emotional Intelligence Scale and the Coaching Efficacy Scale. Structural equation modelling analyses revealed that motivation efficacy and character building mediated the relationship between regulation of emotion and positive and negative coaches’ reactions during game. Specifically, motivation efficacy mediated the association between regulation of emotion and positive coaches’ reactions, and the relationship between regulation of emotion and negative coaches’ reactions were mediated by motivation efficacy and character building. In addition, coaching level moderated the relationships between emotional intelligence, self-efficacy and coaches’ reactive behaviors. Findings of the present study showed that coaching efficacy dimensions (i.e., motivation efficacy and character building) that have the capacity to influence their confidence in ability to affect the psychological mood and positive attitude of athletes, transfer the effects of emotional intelligence (i.e., regulation of emotion) on coaches’ verbal reactions during a youth soccer game. Specifically, a coach who feels competent to regulate their own emotions would perceive high beliefs of efficacy to motivate and to build character of their athletes, and this insight has an impact on their positive verbal reactions in response to athletes’ performances.

The purpose of the present study is to examine the attitudes of Portuguese chartered accountants with respect to questions of ethical nature that can arise in their professional activity. Respondents were asked to respond to the Ethics Position Questionnaire developed by Forsyth (Journal of Personality and Social Psychology 39(1), 175–184, 1980), in order to determine their idealism and relativism levels. Subsequently, they answered questions about five scenarios related to accounting practices, with the objective of measuring their ethical judgments. Based on (...) the idealism and relativism levels of our respondents, they were classified into one of four groups, representing different ethical ideologies (absolutism, exceptionism, subjectivism, and situationism). The results indicated that age was the major determinant of relativism. Contrary to previous research, older respondents revealed themselves significantly more relativistic than younger ones. Gender seems to be the most important determinant of ethical judgments; against expectations, men evidenced significantly stricter judgments than women in two of the five scenarios. Findings also indicated that respondents’ ethical judgments did not differ significantly based on their ethical ideology, supporting the idea that ethical ideology is not an important determinant of ethical judgments.

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without previous use (...) of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

Rescue workers have a stressful and risky occupation where being engaged is crucial to face physical and emotional risks in order to help other persons. This study aims to estimate work engagement levels of rescue workers (namely comparing nurses, firefighters, and police officers) and to assess the validity evidence related to the internal structure of the Portuguese versions of the UWES-17 and UWES-9, namely, dimensionality, measurement invariance between occupational groups, and reliability of the scores. To evaluate the dimensionality, we compared (...) the fit of the three-factor model with the fit of a second-order model. A Portuguese version of the instrument was applied to a convenience sample of 3,887 rescue workers (50% nurses, 39% firefighters, and 11% police officers). Work engagement levels were moderate to high, with firefighters being the highest and nurses being the lowest engaged. Psychometric properties were evaluated in the three-factor original structure revealing acceptable fit to the data in the UWES-17, although the UWES-9 had better psychometric properties. Given the observed statistically significant correlations between the three original factors, we proposed a 2nd hierarchal structure that we named work engagement. The UWES-9 first-order model obtained full uniqueness measurement invariance, and the second-order model obtained partial (metric) second-order invariance. (shrink)

A better understanding of the relative age effect in youth will increase the awareness of the need for reducing the bias of selection. Thus, we investigated the RAE in youth female and male soccer and futsal players in Portugal, using nationwide data. Birthdates of 5,306 female and 126,285 male soccer players, and 2,437 female and 23,988 male futsal players, registered in Portugal during the season 2019–2020, and Portuguese National teams were analyzed. Data were categorized into age groups and certification levels (...) [no certification, basic football training center, football school, and training institution] of the respective clubs/academies. Birthdates were stratified from the start of the selection year using quartiles and semesters. Differences between the observed and expected birthdate distributions were analyzed using chi-square statistics, and RAEs were calculated using odds ratios. In both soccer and futsal, female players, in the age category U9, RAEs were found. In male soccer, differences in the birthdate distribution were observed in all age categories with significant OR between all comparisons. In contrast, an over-representation of young male futsal players was observed only in the age categories U7 and U9. The stratification by certification level showed a significant RAE for all certification levels in male soccer players. In contrast, in male futsal players, the RAE was significant only in clubs and academies with the highest level. For National teams, the RAE was more pronounced in male soccer, particularly in the U16 and U17. Data showed a RAE in female and male youth soccer and futsal, particularly in male, younger age categories, and in clubs and academies having a higher certification level, which could be accompanied by a loss of valuable elite players during the youth phase of their careers. Thus, adjustments in the systems and structure of talent identification are recommended to prevent RAE-related discrimination in youth soccer and futsal. (shrink)

Drawing on feminist and queer epistemologies, this article is concerned with the post-feminist media’s construction of girls’ sexual subjecthood. Broadly defined as a biopolitical ideal, post-feminism is here related to a set of principles of the neoliberal art of government. It will be argued that these principles ethically sustain the exponential mainstreaming of a post-feminist hermeneutics of adolescence and its programme of governmentality. The article also links post-feminism to a particular methodology of subjectification, ultimately locating its hermeneutics of adolescence within (...) the pornographic and pharmacological imperatives of contemporary capitalism. On the empirical level, the analysis explores how techno-scientific discourses and bodily figurations (namely brains and hormones) enter the discursive apparatus of a Portuguese girls’ magazine, giving ideological ground to a distinctive production of adolescent body-subjects. Post-feminist media markets are finally discussed as a significant segment of the capitalist industrialisation of sexual difference that frames the general problematic of this study. (shrink)

This paper addresses the problems of justifying and explaining beliefs about facts in the context of civil trials. The first section contains some remarks about the nature of adjudicative fact-finding and highlights the communicative features of deciding about facts in judicial context. In Sect. 2, some difficulties and the incompleteness presented by Bayesian and coherentist frameworks, which are taken as methods suitable to solve the above-mentioned problems, are pointed out. In the third section, the purely epistemic approach to the justification (...) and the explanation of beliefs about facts is abandoned and focus is given to the dialectical nature of civil procedure, where the parties and, particularly, the judge have to make their reasoning clear enough to allow a fruitful and efficient debate about facts. For this purpose, a communication/argumentation system is put forward, consisting of fourteen intertwined rules of discourse. The system embodies the fundamental epistemic principle according to which belief is updated given new evidence, is tailored for abductive inferences and is structured on fundamental concepts of civil procedural law. The fourth section presents an empirical application of the system to a real case. (shrink)

This study attempts to analyse the relationship between two key psychological variables associated with performance in sports - Self-Determined Motivation and Competitive Anxiety - through Bayesian Networks analysis. We analysed 674 university students/athletes from 44 universities that competed at the University Games in México, with an average age of 21 years (SD = 2.07) and with a mean of 8.61 years’ (SD = 5.15) experience in sports. Methods: Regarding the data analysis, first a CHAID algorithm was carried out to determine (...) the dependence links between variables, and then a Bayesian networks was developed. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantiations were performed with hypothetical values applied to the “bottom” variables. Results showed two probability trees that have extrinsic motivation and amotivation at the top, while the anxiety/activation due to worries about performance was at the bottom of the probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating their scarce influence on anxiety about competition generated by the intrinsic motivation, and the complex probabilistic effect of introjected and identified regulation regarding the appearance of anxiety due to worry about performance.
