The recent global outspread of the COVID-19 pandemic has influenced the lives of people across multiple countries including athletes, coaches, and supporting staff. Along with everybody else, coaches found themselves constrained to an at-home self-isolation, which limited their ability to normally engage with their profession and to interact with their athletes. This situation may also have impacted their own psychological well-being. With this study, we explored coaches’ perceptions of stress in relation to their emotion regulation strategies depending upon their gender (...) and competitive level. A sample of 2272 Italian coaches were surveyed during the period of lockdown. Mean values for perceived stress and emotion regulation strategies were compared to normative data of the two instruments as reported in the original studies. Furthermore, two Multivariate analyses of variance were completed to observe the potential differences in the coaches’ emotion regulation strategies and perception of stress. Finally, a blockwise regression analysis was run to assess how coaches’ emotion regulation strategies impacted upon their perception of stress. Both women and men reported higher levels of perceived stress than those reported in the normative data. Similarly, average scores for emotion regulation strategies were significantly different from those reported for normative data, in particular, coaches reported slightly higher use of emotion regulation strategies than participants in the original study. Significant gender-based differences emerged in terms of emotional regulations, with men adopting more suppression than women. No differences by competitive level were found. In terms of perceived stress, male coaches and elite coaches showed to be more in control of the situation than female coaches and non-elite coaches, respectively, while women experienced more negative stress than men. The blockwise regression evidenced how reappraisal resulted to be predictive in helping coaches to reduce their perception of stress, while suppression predicted higher stress perceptions. (shrink)

When we use secure computer systems, we engage with carefully orchestrated and ordered interactions called “security ceremonies”, all of which exist to assure security. A great deal of attention has been paid to improving the usability of these ceremonies over the last two decades, to make them easier for end-users to engage with. Yet, usability improvements do not seem to have endeared end users to ceremonies. As a consequence, human actors might subvert the ceremony’s processes or avoid engaging with it. (...) Here, we consider whether beautification could be one way of making ceremonies more appealing. To explore beautification in this context, we carried out three studies. Study 1 surveyed 250 participants to derive a wide range of potential dimensions of “beautiful ceremonies”. These statements were sorted into dominant themes and converted into statements, which fed into the second study, with 309 respondents, to reveal the dominant dimensions constituting beauty. Study 3 asked 41 participants to carry out a Q-sort, which revealed the ways that people combine the identified dimensions when characterising security ceremonies as “beautiful”. These studies have allowed us to pin down the perceived dimensions of beauty in the context of security ceremonies, and also to understand how people combine these dimensions in different ways in judging security ceremonies to be beautiful, confirming the old adage of beauty being “in the eye of the beholder”. We conclude by highlighting the constraints imposed by the overarching requirement for security to be maintained in the face of any usability improvements and beautification endeavours. (shrink)

This work presents the concepts of translation and conservative translation between logics. By using algebraic semantics we introduce several conservative translations involving the classical propositional calculus and the many-valued calculi of Post and Lukasiewicz.

During a Barolo en primeur tasting session, a seasoned wine taster is assailed by a procedural unease which leads him to question the foundations on which his work rests. Sparked off by his reading of Michel Le Gris’ pamphlet Dionysos crucifié, the taster’s objections and perplexities are directed towards teasing out the rules and coordinates of a tasting aesthetic which has become tamed and domesticated, at the service of a narcissistic “tyranny of instant gratification”. Such an approach translates into wines (...) that are beaten into submission by interventionist winemakers, wines that derive from a tasting model that has been pre-emptively cleansed of tension or dissonance so as to exalt products that are easy, reassuring, docile to marketing logic, and increasingly similar. What sort of doubts, what interpretative friction can hope to reacquaint wine criticism with its true and original aims? What relations between the tongue that tastes and the tongue that speaks can respond to the needs of a new approach to wine appreciation, a ‘tasting different’? (shrink)

This work presents some basic results on a theory of translations between logics and a short revision about Łukasiewicz's logics. Then, it is shown, using facts about algebraic semantics, that there is a conservative translation from every finite Łukasiewicz's logic into classical logic. However, this is not a constructive result.

Aristotle�s account on natural slavery is neither misleading nor paradoxical, but plausible even though controversial, unlike many commentators think of. On his view natural masters are essentially the virtuous people, viz. those who have been perfected in their process of growing, and natural slaves are essentially the vicious people, viz. those who have been injured or corrupted in some way in their growing up so as to suffer from a lack of autonomous practical rationality. Of course, many barbarians are in (...) this state, but there is no need to presume that all of them are. More to the point, some Greeks will be in this state, especially the many and he who the many have a high regard for. Because of this state, slavery is for the better allowing a slave�s life to become more worthwhile as an instrumental part of the master�s living a good life. Particularly, nature requires that some humans will be able to attain happiness some other will not. Masters and slaves are linked through the rational pursuit of happiness by the political community where they play different roles but equally required. Thus, master and slave will form a single system whose working unity does confirm that a clear separation between that which dominates and that is being dominated must always take place for natural things to be according the best standard.

‘Nomofanie’ sta per “manifestazioni del nómos”. Nel libro si presentano configurazioni concettuali, problemi teoretici e contesti empirici che sono altrettanti dispositivi nomofanici, cioè produttivi di varie e molteplici manifestazioni di quel nómos che la filosofia del diritto è chiamata ad indagare. Quattro i filosofi più richiamati: Aristotele, Tommaso d’Aquino, Kant e Hegel, che costituiscono una sorta di “quadratura” per pensare alcune questioni critiche del vivere-insieme anche nelle società presenti.

This article explores the transformative power of art circulation by analysing surprising narratives of abducted fountains across the early modern Mediterranean area under the political influence of the Spanish Empire. The object of this study will be the stories of Italian fountains stolen by Spanish viceroys or rescued during naval skirmishes between the Holy League and the Ottoman Empire. These narratives reveal a widespread desire for fountains throughout the Mediterranean, which generated a sequence of geographical relocations and cultural translations. My (...) aim is to conceptualise the desire for Italian fountains as an engine for continental circulation, taking into consideration several cases of stolen, abducted, or captive works of sculpture whose stories navigate the dubious boundaries of historical truth and resemble more popular episodes of thefts of relics or the kidnapping and trafficking of enslaved people. Sometimes demonstrable facts, sometimes charming legends linked to the suggestive power of water, these episodes disclose the life of monumental art in motion and subvert the widespread reading of fountains as site-specific objects.

In this paper we present a new hierarchy of analytical tableaux systems TNDC n, 1≤n<ω, for da Costa's hierarchy of propositional paraconsistent logics Cn, 1≤n<ω. In our tableaux formulation, we introduce da Costa's “ball” operator “o”, the generalized operators “k” and “(k)”, for 1≤k, and the negations “~k”, for k≥1, as primitive operators, differently to what has been done in the literature, where these operators are usually defined operators. We prove a version of Cut Rule for the TNDC n, 1≤n<ω, (...) and also prove that these systems are logically equivalent to the corresponding systems Cn, 1≤n<ω. The systems TNDC n constitute completely automated theorem proving systems for the systems of da Costa's hierarchy Cn, 1≤n<ω. (shrink)

In the end of the section 219a 10-21 of the 11th chapter of Physics IV Aristotle defines the ‘before and after’ in movement as follows: «The ‘before and after’ in motion is identical ὅ ποτε ὂυ with motion, yet differs from it τò εἶυατ αύτῷ, and is not identical with motion t (11. 19-21)». These lines convey the answer to the question whether the ‘before’ and after’ are the same thing as movement or not: in one sense, ὅ ποτε ὂυ, (...) they are, in another sense, τò εἶυαι, they are not. But, first and foremost, the opposition of ὅ ποτε ὂυ to то τò εἶυαι is very useful to Aristotle to solve the main aporia of the chapter about the contradictory – at a first sight – and concurrent diversity and identity of the instant, τò υῠυ. Therefore, this aporia will be solved, if only ὅ ποτε ὂυ and то τò εἶυαι mean two really opposing points of view. But what are these points of view? What do they really mean? As it is well known, the phrase ὅ ποτε ὂυ is one of the most enigmatic in the Aristotelian corpus, and yet one of the most important in his physical research because concerns the nature and definition of time. The lower was the agreement among the scholars, with greater force the debate has flared up. An alternative way for attempting to successfully tackle the problem is take in consideration the occurrence of the same phrase in other works than Physica, since the other occurrences of it in the 11th and 14th chapter of the same book are of no help. It is present in only two other works: On Generation and Corruption, I, 3, 319b 3 and Parts of Animals, II, 2, 649a 15; II, 3, 649b 24. In both works we are led to take ὅ ποτε ὂυ as being associated to such terms as ύποκεἰμενον and ύπóκειται. So, Aristotle seems to point out a contrast between a formal respect and a material respect by the opposition of τò εἶυαι to ὅ ποτε ὂυ. The reading of all passages from Physics – particularly, 219a 20-21 – wherein ὅ ποτε ὂυ occurs provides further confirmation of this contrast. As matter of fact, in all three works τò εἶυαι was employed by Aristotle for the same purpose: to set out the difference between a substratum of its own and its ability to actually exist just as substratum underlying worldly things. This difference implies that a substratum cannot but be limited by or relating to time. A condition which is emphasized by the presence of the term ποτε. In conclusion, each instant comes out from the division by the ‘before and after’ of movement’s substratum. If this substratum is found to exist in time, the ‘before and after’ turns out to be ‘what that is now and then’ (ὅ ποτε ὂυ), which, reversely, is the same as the ‘before and after’ in the movement. The occurrences of the incomplete phrase (as ὅ ποτε plus other verbal voices than ὂυ) in other works substantiate this view. (shrink)

In the present article, we introduce an ethical evaluation methodology for clinical cases. Although rejecting proceduralism as a system, we develop a procedure that eventually could be formalized as a flow chart to help carry out an ethical evaluation for clinical cases. We clarify the elements that constitute an ethical evaluation: aim, integration, and how the action is performed. We leave aside the aspect of intentions, focusing on the object of a medical action, arguing that the internal aim of a (...) clinical action carries a moral value per se. Our evaluation system takes into account only objects and circumstances and their intrinsic morality, since we are dealing with the evaluation of a clinical case, and not with a personal and complete clinical action.

In this paper we introduce the concept of conservative translation between logics. We present some necessary and sufficient conditions for a translation to be conservative and study some general properties of logical systems, these properties being characterized by the existence of conservative translations between the systems. We prove that the class constituted by logics and conservative translations between them determines a co-complete subcategory of the bi-complete category constituted by logics and translations.

Este artículo discute el comentario de Alejandro a Aristóteles, Metafísica V.8 1017b23-26. Allí Aristóteles sostiene que la sustancia se dice de dos maneras: (i) el sustrato último, y (ii) la estructura y la forma de cada cosa. En cuanto al primer significado, el comentador apropiadamente pone énfasis en el hecho de que hay una perfecta biunivocidad entre ser sustancia y ser sustrato. Esta biunivocidad, sugiere Abbate, puede verse en las tres entidades que, según el mismo Aristóteles, desde las Categorías –una (...) fórmula reescrita por Alejandro que puede llamarse, en orden creciente, materia, compuesto y forma. De hecho, tales entidades muestran cómo ser el sustrato último significa no ser predicado de nada, un carácter que la forma se realiza por completo cuando es absolutamente inmaterial, en la medida en que no está constituida por referencia de una cosa a otra, menos aún cuál es su sustrato, esto es, la forma como esencia. En cuanto al segundo significado, el comentador parece individualizar tres acepciones diferentes, según las cuales la forma puede llamarse 1) solamente puede ser tal como una forma natural que es inmanente a los cuerpos; 2) como simplemente separada, en un sentido pasivo, de la materia la que se encuentra constitutivamente vinculada. Ésta es la razón por la cual no puede subsistir separadamente, si no virtualmente; como una forma eterna de los cuerpos divinos, no subsistente en relación a cualquier sustrato. De acuerdo con la última acepción, la forma como un motor divino indica una separación completa: tanto la individualidad de una sustancia primera como la trascendencia como una forma pura en acto. Es una sustancia suprasensible, que está separada tanto como el primer motor. Abbate concluye argumentando que Alejandro, por ende, nos autoriza a pensar que el primer carácter, esto es, el carácter que más que cualquier otro acepta la distinción entre aquello que es sustancia y todo lo que no es sustancia, si es cierto que las sustancias más elevadas, las inmateriales, se distinguen de las sustancias materiales en llevar al máximo cumplimiento este carácter.

In this paper we want to analyze some philosophical and epistemological connections between a new kind of technology recently developed within robotics, and the previous mechanical approach. A new paradigm about machine-design in robotics, currently defined as ‘Embodied Intelligence’, has recently been developed. Here we consider the debate on the relationship between the hand and the intellect, from the perspective of the history of philosophy, aiming at providing a more suitable understanding of this paradigm. The new bottom-up approach to design (...) is deeply rooted in a new kind of empiricism, which tries to overcome issues connected with the previous approach strongly committed with the Artificial Intelligence (AI) debate and its origin. Since Turing’s time, the AI debate showed a rationalistic bias which remained undisputed until now. The paradigm shift we are witnessing nowadays is a reply to that bias in order to achieve not only a better way to design robots, but also to understand some underlying epistemological remarks.

In 1999, da Silva, D'Ottaviano and Sette proposed a general definition for the term translation between logics and presented an initial segment of its theory. Logics are characterized, in the most general sense, as sets with consequence relations and translations between logics as consequence-relation preserving maps. In a previous paper the authors introduced the concept of conservative translation between logics and studied some general properties of the co-complete category constituted by logics and conservative translations between them. In this paper we (...) present some conservative translations involving classical logic, Lukasiewicz three-valued system L3, the intuitionistic system I1 and several paraconsistent logics, as for instance Sette's system P1, the D'Ottaviano and da Costa system J3 and da Costa's systems Cn, 1≤ n≤ω.
