This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

The paper presents color as a case study for the analysis of phenomena that pertain to several levels of reality and are typically framed by different sciences and disciplines. Color, in fact, is studied by physics, biology, phenomenology, and esthetics, among others. Our thesis is that color is a different entity for each level of reality, and that for this reason color generates different observables in the epistemologies of the different sciences. By analyzing color as a paradigmatic case of an (...) entity naturally spreading over different levels of reality, the paper raises the question as to whether making explicit the usually implicit ontological assumptions embedded within the different observables exploited by the different sciences may eventually clarify some of the difficulties of developing a comprehensive theory of color.

A recent report from the UN makes the case for “global data literacy” in order to realise the opportunities afforded by the “data revolution”. Here and in many other contexts, data literacy is characterised in terms of a combination of numerical, statistical and technical capacities. In this article, we argue for an expansion of the concept to include not just competencies in reading and working with datasets but also the ability to account for, intervene around and participate in the wider (...) socio-technical infrastructures through which data is created, stored and analysed – which we call “data infrastructure literacy”. We illustrate this notion with examples of “inventive data practice” from previous and ongoing research on open data, online platforms, data journalism and data activism. Drawing on these perspectives, we argue that data literacy initiatives might cultivate sensibilities not only for data science but also for data sociology, data politics as well as wider public engagement with digital data infrastructures. The proposed notion of data infrastructure literacy is intended to make space for collective inquiry, experimentation, imagination and intervention around data in educational programmes and beyond, including how data infrastructures can be challenged, contested, reshaped and repurposed to align with interests and publics other than those originally intended.

Octavio Paz fue un lúcido intérprete de su siglo. Este trabajo explora aspectos decisivos de su propia definición como poeta y ensayista, así como de su trayectoria creativa y crítica, altamente representativa de las transformaciones del artista y el escritor contemporáneos. Los ecos de sus experiencias, prácticas de sociabilidad y lecturas, unidos a su sensibilidad y lucidez, hicieron que ya desde sus primeros textos en prosa Octavio Paz contribuyera a la reconfiguración del ensayo como género. Proponemos leer algunos textos del (...) escritor mexicano en diálogo con las reflexiones de varios de los grandes refundadores del ensayo y la crítica en el siglo XX. Su búsqueda de una comunicación profunda entre poesía e historia, su esfuerzo por repensar críticamente la tradición, su exigencia de autenticidad y libertad en el quehacer del escritor, son algunos de los elementos que dieron lugar en sus ensayos a una nueva poética del pensar y a una nueva relación entre conciencia y transparencia.

Leading invasion biologists sometimes dismiss critics and criticisms of their field by invoking “the straw man” fallacy. Critics of invasion biology are also labelled as a small group of “naysayers” or “contrarians”, who are sometimes engaging in “science denialism”. Such unfortunate labels can be seen as a way to possibly suppress legitimate debates and dismiss or minimize reasonable concerns about some aspects of invasion biology, including the uncertainties about the geographic origins and complex environmental impacts of species, and the control (...) programs against species perceived as “invasive”. In assessing the quality of the debate in this area, we examine the validity of the use of various strategies, including the “straw man” concept, and explore a range of potential logical fallacies present in some recent prominent discussions about invasion biology and so-called “invasive” species. The goal is to add some clarity to the concepts involved, point out some problematic issues, and improve the quality of the debates as the discussions move forward. (shrink)

The Author argues for a non-semantic theory of intentionality, i.e. a theory of intentional reference rooted in the perceptive world. Specifically, the paper concerns two aspects of the original theory of intentionality: the structure of intentional objects as appearance (an unfolding spatio-temporal structure endowed with a direction), and the cognitive processes involved in a psychic act at the primary level of cognition. Examples are given from the experimental psychology of vision, with a particular emphasis on the relation between phenomenal space (...) and colour appearances. (shrink)

Cyclin‐dependent kinases are Ser/Thr protein kinases best known for their cell cycle roles, where CDK1 triggers mitotic onset in all eukaryotes. CDKs are also involved in various other cellular processes, some of which, such as transcription and centrosome duplication, are coupled to cell cycle progression. A new study suggests that the mitotic CDK network is active at low levels in non‐dividing, differentiating precursors of multiciliated cells, and that it drives ciliogenesis. Manipulating the activity of CDK1 or PLK1 altered transitions between (...) the amplification, growth, and disengagement phases, in a manner analogous to the control of passage through different phases of mitosis. How the dynamics of the mitotic kinase network are controlled in these post‐mitotic cells, and whether other cell cycle regulators are also involved, remains unknown. In the present mini‐review we suggest that the redeployment of cell cycle regulators to control steps of differentiation in non‐dividing cells might be a more general, hitherto under‐recognized, feature of cell regulation.

The article presents the preliminary results of the author’s study of the unedited homily De transfiguratione et eleemosyna, ascribed to John Chrysostom. The question of the manuscript tradition is first discussed. The article shows that Maurice Sachot is right when he indicates only the manuscript Romanus Angelicus gr. 125 as a manuscript witness of this homily and that the other two witnesses indicated by Pinakes are erroneous. Then, the descriptions of the folios that preserve the homily are analysed in the (...) light of a new examination of them. This re-examination shows that hitherto several sources that inspired the compiler have gone unnoticed. This is followed by a brief summary of the contents of the homily and an analysis of the passages in which almsgiving is mentioned.Contribution: The article offers a re-examination of the folios 353v–361 from the manuscript Romanus Angelicus gr. 125, the first presentation of the content of the homily De transfiguratione et eleemosyna, and tries to shed light on the association of the theme of the Transfiguration with almsgiving.

Involutive Stone algebras were introduced by R. Cignoli and M. Sagastume in connection to the theory of $n$-valued Łukasiewicz–Moisil algebras. In this work we focus on the logic that preserves degrees of truth associated to S-algebras named Six. This follows a very general pattern that can be considered for any class of truth structure endowed with an ordering relation, and which intends to exploit many-valuedness focusing on the notion of inference that results from preserving lower bounds of truth values, and (...) hence not only preserving the value $1$. Among other things, we prove that Six is a many-valued logic that can be determined by a finite number of matrices. Besides, we show that Six is a paraconsistent logic. Moreover, we prove that it is a genuine Logic of Formal Inconsistency with a consistency operator that can be defined in terms of the original set of connectives. Finally, we study the proof theory of Six providing a Gentzen calculus for it, which is sound and complete with respect to the logic. (shrink)

Cyber risk has become one of the greatest threats to firms in recent years. Accordingly, boards of directors must be continually vigilant about this danger. They have a duty to ensure that the companies adopt appropriate cybersecurity measures to manage the risk of cyber fraud. Boards should also ensure that the firm disclose material cyber risk and breaches. We examine how the board’s gender composition can influence the extent of such disclosure, based on a sample of the companies listed on (...) the S&P/TSX 60 Index over the period 2014–2018. Results show evidence of a positive association between the presence and level of cybersecurity disclosure and board gender diversity. However, the board must boast a critical mass of at least three women before this positive impact can be observed. Our findings contribute to the debate on the importance of gender diversity by adding the concept of the positive influence of heterogeneity on cyber disclosure. We also augment the literature on the critical mass of women in boardrooms by providing empirical evidence that three or more women constitute the threshold for better governance. Our study has important implications for investors, stakeholders and regulators. If investors wish to increase cybersecurity disclosure, they should ask for more diversified boards. Our findings support regulators in their efforts to increase women’s representation on boards by providing empirical evidence of better outcomes with this type of board composition. (shrink)

The contributors to this volume examine recent controversies about the importance of common sense psychology for our understanding of the human mind. Common sense provides a familiar and friendly psychological scheme by which to talk about the mind. Its categories tend to portray the mind as quite different from the rest of nature, and thus irreducible to physical matters and its laws. In this volume a variety of positions on common sense psychology from critical to supportive, from exegetical to speculative, (...) are represented. Among the questions posed are: Is common sense psychology an empirical theory, a body of analytic knowledge, a practice or a strategy? If it is a legitimate enterprise can it be naturalized or not? If it is not legitimate can it be eliminated? Is its fate tied to our understanding of consciousness? Should we approach its concepts and generalizations from the standpoint of conceptual analysis or from the philosophy of science? (shrink)

_El espejo enterrado_ (1992) ocupa un lugar clave en la producción ensayística del escritor mexicano Carlos Fuentes y lo confirma como uno de los más notables intelectuales de nuestro tiempo. La obra y la serie documental a ella vinculada se reprodujeron ampliamente para contribuir a la reflexión en torno al significado de los quinientos años del primer viaje de Colón a través del Océano Atlántico, así como también para pensar la posibilidad de una comunidad iberoamericana apoyada en una historia, una (...) lengua, una tradición cultural y un imaginario compartidos. Este ensayo de interpretación de la vida de América y España se piensa a su vez como una biografía de nuestra cultura y una autobiografía intelectual del propio autor. Fuentes encontró en un año tan significativo como 1992 una oportunidad dorada para escribir la biografía de una cultura que consideró unida por el que llamó “Territorio de la Mancha”, repensar la relación entre España y América y emprender una nueva valoración de su perfil, su destino y su aporte al concierto de las naciones en una nueva etapa del orden mundial.

Starting from the cyclic principle in the process of a society's development, invoking „the end of history" that Hegel mentions, adding the paradoxical principle of Huntington's civilizations, of a unity in diversity, through which we can have a clear and universal image of the conflicts, as actions generated by a cultural-religious interaction, and passing these through the filter of the noble origin of the Occidental civilization, we renew a typology of the inter-societies conflict and we keep the possibility of finding (...) some methods for settling them.

En este artículo, nos proponemos revisar la consigna “Socialismo o Barbarie” en el marco del pensamiento de Rosa Luxemburgo y de Cornelius Castoriadis en vistas a resignificar la acción política en el contexto del neoliberalismo contemporáneo. Consideramos al neoliberalismo, más que como un régimen político o económico, como una “forma de vida” que impacta sobre los modos de ser, de actuar y de pensar de nosotros, hombres y mujeres del siglo XXI. Esta nueva configuración del capitalismo, que se afianza con (...) sus guerras y su creciente pobreza, que deja “a la intemperie” a jóvenes, niños, mujeres, ancianos, hace del neoliberalismo una nueva figura de la barbarie. Por ello, se hace necesario volver a pensar la acción política, el quién, el cómo y el dónde ejercerla en vistas a “transformar la sociedad” y hacer de ella un espacio-tiempo habitable. (shrink)

This book investigates whether treaty interpretation at the ECtHR and WTO, which are sometimes perceived as promoting 'self-contained' regimes, could constitute a means for unifying international law, or, conversely, might exacerbate the fragmentation of international law. In this regard, the practice of the ICJ on treaty interpretation is used for comparison, since the ICJ has made the greatest contribution to the development and clarification of international law rules and principles. Providing a critical analysis of cases at the ICJ, ECtHR and (...) WTO, both prior to and since the adoption of the 1969 Vienna Convention on the Law of Treaties, the book reveals how the ECtHR and WTO apply the general rules of treaty interpretation in patterns which are similar to those used by the ICJ to address difficulties in interpreting the text of treaties. Viewed in the light of the ECtHR's and WTO's interpretative practices, both the VCLT's general rules of interpretation and the ICJ's interpretative practice serve to counteract the fragmentation of international law..
