Features of threatening cues and the associated context influence the perceived imminence of threat and the defensive responses evoked. To provide additional knowledge about how the directionality of a threat (i.e. directed-towards or away from the viewer) might impact defensive responses in humans, participants were shown pictures of a man carrying a gun (threat) or nonlethal object (neutral) directed-away from or towards the participant. Cardiac and electrodermal responses were collected. Compared to neutral images, threatening images depicting a gun directed-towards the (...) participant induced sustained bradycardia and an increased electrodermal response, interpreted as immobility under attack. This defensive immobility reaction is evoked by high perceived threat and inescapable situations and indicates intense action preparation. Pictures of guns directed-away from the participant induced shorter bradycardia and no significant modulation of the electrodermal response compared to neutral pictures, which might be consistent with the perception of a less threatening situation. The results show that the directionality of threat stimuli is a key factor that prompts different patterns of defensive responses. (shrink)

It is assumed that social bonds in humans have consequences for virtually all aspects of behavior. Social touch-based contact, particularly hand caressing, plays an important role in social bonding. Pre-programmed neural circuits likely support actions (or predispositions to act) towards caressing contacts. We searched for pre-set motor substrates towards caressing by exposing volunteers to bonding cues and having them gently stroke a very soft cloth, a caress-like movement. The bonding cues were pictures with interacting dyads and the control pictures presented (...) non-interacting dyads. We focused on the readiness potential, an electroencephalographic marker of motor preparation that precedes movement execution. The amplitude of the readiness potential preceding the grasping of pleasant emotional-laden stimuli was previously shown to be reduced compared with neutral ones. Fingers flexor electromyography measured action output. The rationale here is that stroking the soft cloth when previously exposed to bonding cues, a compatible context, would result in smaller amplitudes of readiness potentials, as compared to the context with no such cues. Exposure to the bonding pictures increased subjective feelings of sociability and decreased feelings of isolation. Participants who more frequently engage in mutual caress/groom a “significant other” in daily life initiated the motor preparation earlier, reinforcing the caress-like nature of the task. As hypothesized, readiness potentials preceding the caressing of the soft cloth were significantly reduced under exposure to bonding as compared to control pictures. Furthermore, an increased fingers flexor electromyographic activity was identified under exposure to the former as compared to the latter pictures. The facilitatory effects are likely due to the recruitment of pre-set cortical motor repertoires related to caress-like movements, emphasizing the distinctiveness of neural signatures for caress-like movements.

Binge-purge eating disorders, such as bulimia nervosa and binge eating disorder, may share some neurobiological features. Electroencephalography is a non-invasive measurement modality that may aid in research and diagnosis of BP-ED. We conducted a systematic review of the literature on EEG findings in BP-ED, seeking to summarize and analyze the current evidence, as well as identify shortcomings and gaps to inform new perspectives for future studies. Following PRISMA Statement recommendations, the PubMed, Embase, and Web of Science databases were searched using (...) terms related to “electroencephalography” and “binge-purge” eating disorders. Of 555 articles retrieved, 15 met predefined inclusion criteria and were included for full-text analysis. Eleven studies investigated EEG by means of event-related potentials in BP-ED individuals: 7 using eating disorder-related stimuli and 4 using non-eating disorder-related stimuli. These studies found significant differences in the N200, P200, P300, and LPP components in BP-ED participants compared to controls, indicating that this population exhibits impairments in selective attention, attentional allocation/processing, and allocation of motivational or emotion-based attention. Five studies investigated EEG using frequency analysis; reporting significant differences in beta activity in fronto-temporal and occipito-temporo-parietal areas in BP-ED individuals compared to controls, revealing a dysfunctional brain network. However, the small number of studies, the heterogeneity of samples, study paradigms, stimulus types, and the lack of an adequate assessment of neuropsychological parameters are some limitations of the current literature. Although some EEG data are promising and consistent with neuroimaging and neuropsychological findings in individuals with BP-ED, future studies need to overcome current methodological shortcomings.

Proximity and interpersonal contact are prominent components of social connection. Giving affective touch to others is fundamental for human bonding. This brief report presents preliminary results from a pilot study. It explores if exposure to bonding scenes impacts the activity of specific muscles related to physical interaction. Fingers flexion is a very important component when performing most actions of affectionate contact. We explored the visuo-motor affective interplay by priming participants with bonding scenes and assessing the electromyographic activity of the fingers (...) flexor muscle, in the absence of any overt movements. Photographs of dyads in social interaction and of the same dyads not interacting were employed. We examined the effects upon the electromyographical activity: during the passive exposure to pictures, and during picture offset and when expecting the signal to perform a fingers flexion task. Interacting dyads compared to matched non-interacting dyads increased electromyographic activity of the fingers flexor muscle in both contexts. Specific capture of visual bonding cues at the level of visual cortex had been described in the literature. Here we showed that the neural processing of visual bonding cues reaches the fingers flexor muscle. Besides, previous visualization of bonding cues enhanced background electromyographic activity during motor preparation to perform the fingers flexion task, which might reflect a sustained leakage of central motor activity downstream leading to increase in firing of the respective motor neurons. These data suggest, at the effector level, an implicit visuo-motor connection in which social interaction cues evoke intrinsic dispositions toward affectionate social behavior. (shrink)

Of recent time, there has been a concern about ethical leadership and ethics in business. Research on leadership did not pay a lot of attention to fairness and many authors have studied the relationship between leader fairness and factors such as outcome satisfaction and trust in leader for instance. For the moment, there is no study that focused on the direct relationship between transformational leadership and fairness. That’s why; in this paper our aim is to study the relationship between transformational (...) leadership and the employees’ perceptions of fairness, mainly the three types of fairness which are distributive, procedural, and interactional in French firms. A questionnaire survey was sent to employees working in the industry and service sectors. A sample of 100 respondents was collected. We found a partial relationship between employees’ perceptions of fairness and transformational leadership. More specifically, we found that procedural and interactional fairness are strongly associated with transformational leadership. (shrink)

The Phaedo and the Symposium are dialogues in which Plato's conception of philosophy is not dissociated of orphic elements and mythical constructions. I propose that the themes of the pre-existence of the soul and the immortality of the soul in the Phaedo and myths told by Aristophanes and Diotima in the Symposium, examined together, provide rich material for understanding the nature and limits of knowledge and philosophy in Plato. I also suggest, before this interpretation, a reading of the "sudden vision (...) of beauty in itself," in Symposium 210e, which takes into account these limits. Knowledge is, from this reading, a dynamic search, much more than intuition of the forms. (shrink)

RESUMO Este artigo contempla nosso estudo de práticas socioculturais que demonstram que/como o sujeito contemporâneo dialoga online com enunciados advindos de acontecimentos do universo off-line. Nosso corpus apresenta postagens circuladas publicamente em páginas diversas no Facebook em que se lê: “É verdade esse bilete”. A afirmativa, proveniente de um bilhete escrito por uma criança em sua esfera familiar e divulgado em redes sociais, foi apropriada por múltiplos interlocutores no ciberespaço a fim de produzir efeitos de humor e dizeres contraditórios em (...) diferentes instâncias discursivas. Para a análise, recorremos a elementos constitutivos do dialogismo de proposição bakhtiniana; aos conceitos de meme e remix e às discussões foucaultianas acerca da vontade de verdade. Nossas interpretações apontam que é possível rastrear, nas réplicas ativas analisadas, posições axiológicas que nos remetem ao sujeito contemporâneo, o qual, usando a ironia e efeitos de humor, constitui/compartilha enunciados no intuito de estabelecer sua vontade de verdade na ágora digital. ABSTRACT This paper presents a study of sociocultural practices that exemplify how subjects interact online with offline events. We analyse selected posts collected from social media profiles supported by Facebook. Each excerpt shows the affirmative “It’s true this notte,” a rough translation of a written message addressed by a four-year-old Brazilian boy to his mother stating that there would “supposedly” be a school holiday the following day. The note went viral after his teacher posted it publicly on her social media timeline and the reassuring assertion was appropriated multiple times in the cyberspace so as to as trigger a humour effect in different discourse instances. Grounded on the concepts of meme; remix; Bakhtinian dialogism and Foucauldian’s ideas on truth, we perform a discursive analysis. Our results point to track marks of axiological positions of contemporary subjects that resort to irony to construct/share utterances in order to establish their will to truth in the digital landscape.

O texto aborda a relação da educação escolar e o catolicismo no espaço rural, especialmente, no rio Mapuá, no município de Breves, arquipélago de Marajó, estado do Pará. Tem-se por objetivo identificar a presença do catolicismo na escola do campo e a relação com a formação dos alunos ribeirinhos. Especificamente, a perspectiva é discutir a influência dos rituais religiosos e artefatos sagrados no processo educativo e na cultura escolar do campo. É uma investigação de natureza qualitativa, fundamentada na incursão bibliográfica (...) e pesquisa de campo, cujos dados empíricos foram coletados por meio de observações etnográficas, entrevistas semiestruturadas e fotografias. Em termos teóricos o estudo busca amparo em escritos de autores do campo da Antropologia, Ciência da Religião e da Educação, tendo como recorte o ensino religioso. Os resultados indicam que a educação escolar e o catolicismo no rio Mapuá entrelaçam-se por meio de rituais e artefatos sagrados que narram saberes, tradições, afetos, significados e simbologias que na percepção dos depoentes ajudam a forjar a formação escolar dos sujeitos e, por conseguinte, à cultura escolar.

Este texto, bem como as pesquisas que realizamos, tem como meta dar visibilidade às leituras literárias destinadas ao público infantil e juvenil, que enfatizem o tema étnico-racial, ou ainda, títulos que incluam a real participação de personagens negras, costumes afro-brasileiros e informações culturais produtoras de identificação entre o leitor e a narrativa, contribuindo, assim, com as mudanças atuais na história da educação brasileira. Neste texto, apresentamos seis títulos da Editora SM, que, em seu catálogo editorial para 2008/2009, dos 173 títulos (...) publicados, 20 títulos trazem a presença da cultura africana e afro-brasileira. Dos 20, optou-se pela análise de cinco títulos. Da análise desses títulos, constatou-se, acima de tudo, que um dos caminhos para o entendimento e a consciência acerca da pluralidade cultural está também na apropriação da leitura literária produtora de identidade e inclusão social.

Rédigé par deux féministes qui avaient vingt ans dans les années 1970, dont l’une est devenue biologiste et l’autre spécialiste des relations de pouvoir entre les sexes, cet article postule que l’humanité est en train de vivre un nouveau tournant dans cette histoire, en ce que la fin de la domination masculine est désormais envisageable. Or si l’égalité femmes-hommes est aujourd’hui plus légitime que jamais, elle suscite toujours des oppositions farouches – alors même que les certitudes établies sur « les (...) deux sexes » vacillent au gré des progrès de la science et de la médecine. Cette nouvelle étape exige de celles et ceux qui veulent voir progresser ce chantier de rompre avec les travers issus du temps de la marginalité, et d’acquérir les connaissances scientifiques et historiques dont le manque pourrait faire le jeu de leurs opposant·es.

Violence is often understood as a phenomenon characterized by direct physical harm customarily motivated by willful malice. In his 2017 World Day of Peace Message, Pope Francis challenges this narrow definition, noting that violence is not confined to physical harm but also includes environmental devastation, which, as he points out, disproportionately harms the most vulnerable members of the planet. Following this claim, this article probes the interrelationship between care for creation, nonviolence, and racial justice, highlighting the significance of this intersectionality (...) within Catholic social teaching. It reflects on Francis’s reading of Gospel nonviolence and his notion of integral ecology, and concludes with a case study that demonstrates the practical application of Francis’s social teachings on creating a more just, nonviolent, and sustainable world.

La France a connu, dans la seconde moitié du XVIe siècle, près de quarante années de conflits civils et religieux, dans lesquels les femmes, toutes sortes de femmes, ont été très présentes. Comme cibles des crimes de guerre bien entendu, mais aussi comme comploteuses, comme espionnes, comme propagandistes, comme négociatrices des paix ­ et même comme combattantes, à la défense des villes ou des châteaux, « pique à la main ». Cette activité des femmes, que soulignent toutes les sources, s'explique (...) par divers phénomènes sociaux, politiques et culturels propres à la Renaissance ­ notamment la vigueur du débat sur le rapport des femmes au pouvoir (la dernière guerre civile ayant divisé partisans et détracteurs de la loi salique). Histoire patente, passionnante, et pourtant effacée : absente des livres d'Histoire, éradiquée de la mémoire des Français. C'est qu'elle touche à la guerre, à la paix, à la violence, à la vie de la cité : au cœur de la domination masculine. (shrink)

Elian Cuvillier Cet article propose une manière d’appréhender le langage apocalyptique propre à Jean de Patmos à travers l’analyse de deux types de données : temporelles et spatiales. Il montre sa fécondité herméneutique et ainsi sa potentielle actualité pour appréhender le temps et l’espace qui sont les nôtres. La lecture de l’Apocalypse ouvre l’espace et le temps d’une imagination créatrice qui se veulent résolument en écart de l’angoisse et de l’enfermement caractérisant à maints égards notre monde présent.

Publication d'un miroir à boîte, provenant d'une tombe fortuitement découverte à Lamia en 1983. Le type du miroir et l'étude iconographique et comparative de la représentation en relief du couvercle se rapportant à une scène dionysiaque mettent en évidence son caractère attique, ainsi que sa datation aux environs du dernier quart du ive s. av. J.-C. Les éléments iconographiques analysés ici sont rapprochés de parallèles provenant tant de la sculpture et de la céramique que des terres cuites et des bronzes. (...) On constate que certains types et motifs de cette nouvelle représentation remontent à la dernière phase du ν s. av. J.-C, ce qui prouve, une fois encore, l'importance de l'influence du langage artistique de cette période sur les arts mineurs en général, et sur l'évolution de la toreutique en particulier. Ainsi sont mis en lumière des rapports étroits entre l'imagerie du ive s. avancé et celle des dernières décennies du ve s., phénomène qui va se poursuivre par la suite avec des variations. Les questions de la composition et de la signification de la scène sont brièvement traitées. (shrink)

De modo semelhante aos rompantes etnocêntricos de uma cultura humana frente a outras, as relações entre humanos e primatas não humanos incluem um estranhamento pontuado por atração e repulsa, identificação e diferença. Ciência, arte e mitologia são a expressão viva e atualizada disso. Desde 1960, a primatologia destaca-se nesse cenário por contribuir significativamente na revisão das definições sobre o comportamento dos primatas e, consequentemente, na redefinição do humano ao apresentar a polêmica proposição de existência de "culturas" entre animais não humanos. (...) Assim, a aproximação entre humanos e primatas não humanos parece inexorável e irreversível. Isso implica, por exemplo, em cogitar se esse processo engendra, ou não, a constituição de novas alteridades a partir de um novo outro (não humano), carregado de significados. Isso incluiria, por exemplo, a reformulação de representações e de categorias de classificação, bem como o aprofundamento do debate sobre os direitos dos animais não humanos. Ao dirigir tal tipo de desafio a situações de pesquisa antropológica deve-se ter aguda consciência de que o registro etnográfico das relações entre humanos e os outros primatas será uma construção empírica, perceptual e teórica. Dado o tipo particular de relação estabelecida entre humanos e outros primatas, pautada em um universo fronteiriço de incômodas semelhanças e diferenças, constituem-se aí coletivos híbridos em que o alcance e a profundidade das interações possíveis ainda são desconhecidos. The relations between humans and non-human primates resemble the ethnocentric reaction of one human culture in relation to others, and include an estrangement marked by attraction and rejection, identification and differentiation. Art, science and myths are the vivid and updated expression of these phenomena. Since the 1960's primatology stands out in that scenario for contributing significantly to the revision of the definitions about the behavior of primates and, consequently, for the redefinition of human beings, and for making the controversial proposal of the existence of non-human animal "cultures". Then, the close connection between humans and non-human primates seems relentless and irreversible - and raises the question on whether or not these processes engender a new kind of otherness deriving from a non-human other that is full of meaning. This would include, for example, the reformulation of the representations and categories of classification, as well as deepening the debate about the rights of non-human animals. When the challenge is taken up in situations of anthropological research that address the relationships between human beings and the other primates, the ethnographic register that describes the relations between human beings and other primates will be an equally sharp empirical, perceptual and theoretical construction. Given the peculiar type of relationship established between human beings and other primates, implemented in a frontier universe of uncomfortable similarities and differences, they constituted a hybrid collective where interactions are possible but we do not know exactly how complex or how depth they are.

This work scrutinizes different elements of a philosophical disagreement about the understanding of justice between John Rawls and Gerald Cohen. Rawls uses the original position device where representative members of society hypothetically meet to select the best principles for their social cooperation. More convincing seems Cohen s conceptual analysis method which proposes an unveiling of the concept of justice in order to judge what is just.".

Resenha do livro de Dermeval Saviani, Escola e Democracia.

Platão, ao tratar da negação no diálogo Sofista, afirma que sempre que enunciamos o que não é, não enunciamos algo contrário ao que é, mas algo diferente. A negação significa cada parte da natureza da diferença em antítese ao que é. Tal tratamento da negação resulta da necessidade de resolver alguns problemas colocados pelo eleatismo. Propõe-se indicar esses problemas e examinar o tratamento que Platão dá ao nãoser como diferença.

No Teeteto, em uma tentativa de denir o conhecimento, Platão trata da unidade e da complexidade segundo um modelo de análise dos complexos em elementos simples não analisáveis. Wittgenstein, no parágrafo 46 das Investigações Filosócas, cita esse argumento do Teeteto, introduzindo uma crítica à sua própria noção de objeto, no Tractatus. Nosso tema será um exame das noções de elemento e composto, apresentadas no Teeteto e retomadas no Sosta, tendo como horizonte a aproximação, feita por Wittgenstein, entre o objeto do (...) Tractatus e o elemento do Teeteto. (shrink)

Les paysannes ont-elles une histoire? Leur parcours semble défier l'évolution « classique » de l'émancipation féminine. Elles échappent à la chronologie élaborée au cours de ces dernières années par l'histoire des femmes, elles restent en marge des grands moments fondateurs. Ni les luttes politiques autour de l'éducation des filles, ni l'émergence du féminisme – fait principalement urbain – ni celle du syndicalisme et des premiers jalons de la législation sociale n'influencent leur condition...
