Purpose: This study is aimed to preliminary investigate whether transcranial alternating current stimulation could affect explosive power considering genetic background in sport subjects.Methods: Seventeen healthy sports volunteers with at least 3 years of sports activities participated in the experiment. After 2 weeks of familiarization performed without any stimulation, each participant received either 50 Hz-tACS or sham-tACS. Before and after stimulation, subjects performed the following tests: the squat jump with the hands on the hips ; countermovement jump with the hands on (...) the hips ; countermovement jump with arm swing ; 15-s Bosco’s test; seated backward overhead medicine ball throw ; seated chest pass throw with a 3-kg rubber medicine ball; and hand-grip test. Additionally, saliva samples were collected from each participant. Genotyping analysis was carried out by polymerase chain reaction.Results: No significant differences were found in sport performance of subjects after 50 Hz-tACS. Additionally, we did not find any influence of genetic background on tACS-related effect on physical performance. These results suggest that tACS at gamma frequency is not able to induce an after-effect modulating sport performance. Further investigations with larger sample size are needed in order to understand the potential role of non-invasive brain stimulation techniques in motor performances.Conclusions: Gamma-tACS applied before the physical performance fails to improve explosive power in sport subjects.

The time marked by the clock hands, the so-called “objective time,” is deeply different from the one perceived by the individual. Starting from this hypothesis, directly connected to the subjective modality of “living” the time and defined as time perspective, we will try to understand how much it affects the various domains of people's lives, attitudes, and experiences. Therefore, the research investigates whether all our decisions can be influenced by one or more time perspectives beyond our awareness. Last, but not (...) least, we will try to understand if some time perspectives in specific contexts are more functional and adaptive than others. (shrink)

For many years, psychological–clinical research has been aiming at studying the Mafia from different viewpoints: the man of honor's inner world, relational and psychopathological structures of his family matrices, connections between inner and social worlds, interiorized and social rules. Today, however, a complex phenomenon has come to light, which concerns the great connection between the Mafia and financial crime, and for us as researchers it is very interesting and complicated to analyze, because it involves the study of psychological peculiarities that (...) can be specifically found in the numerous illegalities. The crossbreeding of the various criminalities, which are always more interacting and merging and less isolated, makes this picture even more complex. (shrink)

Dans mon article, je vais essayer de développer une analyse de deux des plus importants chapitres du De anima d'Aristote : les chapitres 4 et 5 du livre III, où Aristote propose son traitement de la question de l'intellect. Sans entrer dans les détails de l'histoire de l'interprétation de ce texte, je propose d'identifier l'intellect dit ‘passif’ avec quelques traits distinctifs de la puissance de la phantasia ou imagination, et ce que l'on appelle ‘l'intelligence productive’ avec l'environnement cosmique, qui, en (...) vertu de ses régularités, produit les habitats qui vont agir sur la puissance sensorielle de l'être humain et qui, dans la production des expériences sensorielles de l'être humain, fera passer son esprit du statut d'intellect passif à celui d'intellectus in habitu.

The recent in vitro derivation of gamete‐like cells from mouse embryonic stem (mES) cells is a major breakthrough and lays down several challenges, both for the further scientific investigation and for the bioethical and biolegal discourse. We refer here to these cells as gamete‐like (sperm‐like or oocyte‐like, respectively), because at present there is still no evidence that these cells behave fully like bona fide sperm or oocytes, lacking the fundamental proof, i.e. combination with a normally derived gamete of the opposite (...) sex to yield a normal individual. However, the results published so far do show that these cells share some defining features of gametes. We discuss these results in the light of the bioethical and legal questions that are likely to arise would the same process become possible with human embryonic stem (hES) cells. (shrink)

The usual representation of quantum algorithms, limited to the process of solving the problem, is physically incomplete. We complete it in three steps: extending the representation to the process of setting the problem, relativizing the extended representation to the problem solver to whom the problem setting must be concealed, and symmetrizing the relativized representation for time reversal to represent the reversibility of the underlying physical process. The third steps projects the input state of the representation, where the problem solver is (...) completely ignorant of the setting and thus the solution of the problem, on one where she knows half solution. Completing the physical representation shows that the number of computation steps required to solve any oracle problem in an optimal quantum way should be that of a classical algorithm endowed with the advanced knowledge of half solution.

A great deal of "epistemological" thought is dedicated to the question of the origin of the ideas that form our ordinary conception of reality.1 How do we obtain our view of the world as a whole composed of discrete substances, endowed with space-time extension, which are the substrata of specific qualities, linked to each other by different kinds of relation?This is a question that is certainly less problematic in contexts of thought that defend "pluralist" ontologies—where being is thought to amount (...) to a plurality of discrete and self-subsistent entities.

"El método seguido puede llamarse con una sola palabra comparativo. He tratado, en efecto, de que las ideas y los hechos procedan a la par, ayudándome también a veces del estudio de los vocablos, con los cuales las unas y los otros han sido expresados; he hecho que caminasen de frente los varios pueblos que concurrieron más eficazmente al desenvolvimiento de las instituciones jurídicas y sociales, así como también a los diferentes sistemas escogidos por los autores, y he procurado, por (...) fin, poner de relieve la correlación constante entre la vida económica, jurídica y moral en los distintos períodos de la historia y el concierto admirable que siempre se manifiesta entre las varias partes del organismo social. Presento este ensayo tal como ha llegado a ser después de varios años de trabajo y estudio, debiendo limitarme a hacer observar que, por razón de la lógica que lo rige, las varias partes de que consta se suponen recíprocamente por modo tal, que los primeros capítulos son la preparación indispensable para la inteligencia de los siguientes, y los últimos sirven de ilustración y complemento a los primeros. Por mi parte habré alcanzado el objeto que me proponía si logro infundir en alguno de mis lectores la profunda convicción que tengo de que el estudio del mundo social y humano ofrece tantos goces y no menores maravillas al sociólogo, como al físico y al naturalista el estudio del mundo material y orgánico, y que las investigaciones libros y sin prejuicios acerca de las instituciones primitivas de la sociedad, lejos de conmover las eternas convicciones del género huma-no, logran al fin confirmarlas científicamente".

A interpretação da filosofia de Nāgārjuna como um niilismo metafísico radical é comum tanto entre os autores antigos quanto nos estudos budológicos contemporâneos. Uma primeira leitura da doutrina da vacuidade proposta por esse autor, com efeito, parece levar à conclusão de que nada existe em última análise e, portanto, a realidade em si seria equivalente a um puro não-ser. Uma tal metafísica do nada, entretanto, seria duplamente problemática: primeiramente, ela parece sofrer de graves incovenientes lógico-conceituais; em segundo lugar, ela colocaria (...) Nāgārjuna fora da ortodoxia budista, por ser o niilismo uma doutrina explicitamente reprovada pelo Buda histórico. Uma leitura mais atenta e completa dos textos a nossa disposição, entretanto, nos leva a concluir que a filosofia do fundador da escola Madhyamaka não pode ser considerado como um niilismo metafísico, mas sim, ao invés disso, como uma tentativa de evitar e de eliminar qualquer metafísica, tanto afirmativa quanto negativa, em total acordo com o programa filosófico – já presente no ensinamento do Buda – do “caminho do meio”, equidistante das categorias do ser e do não-ser.

With regards the crucial issue of the existence of the self, within canonical texts of the Buddhist Abhidharma schools we find passages that are frequently at odds with one another. Sometimes the Buddha defends or respects the belief in the self and in personal continuity; at other times he seems to deny that beyond the psycho-physical factors to which our existential experience can be reduced there is an ātman that contains, owns or controls these same factors; in further cases still, (...) he states that the use of the metaphysical categories of “being” and “non-being” must be avoided – thus, about the self (or everything else), it is inappropriate to say that it exists or that it does not exist. Faced with these divergences (or contradictions) within contemporary Buddhist studies, we can detect two main tendencies. Some scholars start from the assumption that the Buddha’s teaching is or should be coherent and univocal, and, therefore, propose readings of his original message that are supposed to iron out or conciliate any inconsistencies. Others believe that the inconsistencies are actually irreconcilable and, therefore, maintain that the Abhidharma canons are a composite and stratified redaction in which the opposite views of different writers overlap and intersect. Against these historiographical approaches, the purpose of the present paper is to show that the three aforementioned modes of the Buddha’s teaching are, in fact, both alternative and irreconcilable. This, however, far from presenting a puzzle to be solved or explained (by resorting to suppositions of which, in the canons, we have no explicit confirmation), is nothing more than a feature of the Buddha’s Dharma, which appears to be a teaching that develops different pedagogical/soteriological modes for different purposes, and which is conceived for the spiritual growth of followers with different intellectual and psychological profiles.

125. The madman. Have you not heard of that madman who lighted a lantern at the bright sunshine of the morning, ran to the market, and began ceaselessly screaming: "I seek God! I seek God!"?This present essay is a shortened and adapted version of the first chapter of a large book of mine devoted to a comparison between ancient Greece and Christianity, shortly to be published in English by Michigan State University Press. Its theoretical core is the idea of mediation, (...) that is to say, the intangible connective element acting as a medium capable of linking humans to the world and the divine sphere that made the world possible in ancient times2.

This short essay explores the importance of fear and violence in the genesis and life of constitutions, with a particular focus on the case of secession. Secession has been seen as a taboo and until recently constitutions tried to avoid mentioning it, considering such a phenomenon as an extra legal fact. A turning point has been represented by the famous Reference of the Canadian Supreme Court on Québec. Finally, in the last part of this work I shall try to present (...) some arguments in favour of the explicit constitutionalization of a secession clause in multi-national federalisms. (shrink)

L’auteur propose ici un commentaire sur les points les plus importants de son entretien de février 2003 avec Paul Ricœur consacré aux rapports entre herméneutique et psychanalyse. Bien que le philosophe se situe dans une réelle continuité par rapport à sa contribution de 1965, il enrichit toutefois sa réflexion philosophique sur la psychanalyse en proposant plusieurs innovations, en ce qui concerne plus particulièrement les thèmes du récit, du soi et de l’éthique. Dans les conclusions de son commentaire, l’auteur souligne l’importance (...) des concepts d’“irreprésentable” et d’“intraduisible”: non seulement, en effet, ces concepts sont dans la ligne de nombreuses contributions de la psychanalyse contemporaine, mais la profondeur de la réflexion ricœurienne augmente en outre leur potentiel théorique et même clinique.
