El punto de partida wittgensteiniano del Tractatus según el cual el mundo y el lenguaje poseen una estructura común, y la expresión del pensamiento es perceptible mediante las proposiciones lingüísticas, mediante signos lingüísticos que proyectan las situaciones a través del sentido de las proposiciones, es revisada en las Investigaciones Filosóficas, en las que Wittgenstein subraya quela relación entre una palabra y su significado no se da en la teoría, sino en la práctica, en los usos lingüísticos de la palabra. La (...) técnica filosófica de los juegos del lenguaje sirve como terapia al librarnos de las confusiones filosóficas causadas por la consideración del lenguaje al margen de los contextos y actividades vitales, al margen de las formas de vida. A partir de esta idea se reflexiona sobre algunos importantes aspectos en los que la filosofía del lenguaje incide en el ámbito jurídico: la validez normativa, la tipología de las normas, la jerarquía normativa, la lógica normativa y la semiótica normativa.

The Coronavirus Covid 19 pandemic has produced terrible effects in the world economy and is shaking social and political stability around the world. The world of sport has obviously been severely affected by the pandemic, as authorities progressively canceled all level of competitions, including the 2020 Olympic Games in Tokyo. In Spain, the initial government-lockdown closed the Sports High-performance Centers, and many other sports facilities. In order to support athlete's health and performance at crises like these, an online questionnaire named (...) RECOVID-19, was designed to assess how athletes were living their lives during such periods of home confinement. The main purpose of the questionnaire was to assess the impact of prolongued confinement on athlete's psychological, emotional, and behavioral performance. One thousand, two hundred forty-eight athletes participated in the survey. They had the fllowing characteristics:, who compete at National and International level. Results showed that during the confinement period, those athletes who lacked motivation reported a higher level of stressful thoughts, more behavioral problems, and greater emotional upheaval. However, those athletes who accepted confinement measures as necessary, and were in favor of respecting the rules of social isolation, fostered positive emotional states such as feelings of friendship. In addition, the availability of some sport equipment together with the ability to continue some training, were protective factors against emotional stress, lack of motivation and behavioral problems; and they were associated with greater respect for, and adherence to, confinement rules. Gender differences, tested by multigroup analysis, revealed that coping activities were more often associated to negative emotional states among women, whereas the ongoing availability of training information and future conditions were equally protective factors for both genders. This study also showed that receiving coaching, support and completing frequent training routines seem to be valuable tools to prevent or reduce some of the harmful effects of isolation on athlete's emotional well-being. The conclusions derived from this research would possibly help sport authorities to design supporting policies and plans to support athletes and trainers in future disruptive health crises. (shrink)

This research aimed to examine the agreement between body mass index -based nutritional status and perceived nutritional status overall and by socio-demographic factors and to state the association between the accuracy of weight perception and weight control practices in the Chilean adult population. A population-based cross-sectional study was carried out with 5,192 Chilean adult participants from the Chilean National Health Survey 2016–2017. Agreement between BMI-based weight status and body weight perception for the total sample and across subgroups was determined using (...) the weighted kappa coefficient. The agreement between BMI-based and perceived nutritional status of the total sample was fair. A higher rate of weight perception accuracy was identified in women, younger respondents, and participants with higher education, a higher income, and from urban areas than their counterparts. Respondents with overweight or obesity tended to underestimate their nutritional status. Actions to lose weight were higher in those who had the right perception of their overweight/obesity condition and those who overestimated their body weight, regardless of their nutritional status. In all groups, weight loss behaviors were more related to the perceived than the BMI-based nutritional status. The consequences of accurate perception of the nutritional status are discussed including its effects on body weight and mental health. (shrink)

As ideias estão em Deus e são compreendidas por seus limites em relação à sua essência ilimitada. A originalidade do ser de Tomás de Aquino pode ser testada se comparada com as múltiplas teorias a respeito da ideia que se desenvolveram ao longo dos séculos na investigação filosófica. Das ideias subsistentes de Platão à ideia como subsistência em Hegel, os percursos aristotélico e tomista revelam-se opções intelectuais moderadas no âmbito gnosiológico, em razão de suas conquistas metafísicas. Deixando de lado os (...) problemas gnosiológicos em favor de uma abordagem metafísica do problema da ideia, pode-se perceber que, para Tomás, tanto o valor do conceito na ordem gnosiológica, quanto a subsistência da ideia na ordem metafísica, se resolvem apenas em ordem ao ser. A terceira das Quaestiones Disputatae De Veritate aborda diretamente o problema e traz sua formulação definitiva no pensamento de Tomás. Todas as perfeições das ideias estão em Deus formaliter, pertencem à sua essência, mas a ideia da essência divina somente Deus a conhece, pois identifica-se com seu ser, o Ipsum Esse Subsistens.

Background: The coronavirus disease 2019 pandemic is impacting the delivery of healthcare worldwide, creating dilemmas related to the duty to care. Although understanding the ethical dilemmas about the duty to care among nurses is necessary to allow effective preparation, few studies have explored these concerns. Aim: This study aimed to identify the ethical dilemmas among clinical nurses in Spain and Chile. It primarily aimed to (1) identify nurses’ agreement with the duty to care despite high risks for themselves and/or their (...) families, (2) describe nurses’ well-being and (3) describe the associations between well-being and the duty to care. Research design: Cross-sectional self-reported anonymous data were collected between May and June 2020 via electronic survey distribution (snowball sampling). Ethical considerations: The Institutional Ethical Review Committees in both countries approved the study (CHUC_2020_33 and 27/2020). Findings: In total, 345 clinical nurses answered the primary question about the duty to care for the sick. Although in the total sample 77.4% agreed they have a duty to care for the sick, significant differences were found between the Spanish and Chilean samples. Overall, 53.6% of the nurses reported low levels of well-being; however, among those reporting low well-being, statistically significant differences were found between Spanish and Chilean nurses as 19.4% and 37.8%, respectively, disagreed with the statement regarding the duty to care. Discussion: Participants in both countries reported several ethical dilemmas, safety fears, consequent stress and low well-being. These results suggest that prompt actions are required to address nurses’ ethical concerns, as they might affect their willingness to work and psychological well-being. Conclusion: Our findings shed light on the ethical dilemmas nurses are facing related to the duty to care. Not only has the coronavirus disease 2019 pandemic given rise to ethical challenges, but it has also affected nurses’ well-being and willingness to work during a pandemic. (shrink)

This book introduces readers to central concepts and ideas in Mexican philosophy. Couched in stories and anecdotes from the author's life, the book offers these concepts and ideas as orientations, recommendations, or exhortation for navigating today's world. The structure and the style of the book aims at making these accessible to both specialists and non-specialist or anyone who may have had some experience with contemporary forms of marginalization, alienation, objectification, or any of the various forms of dread and accidentality familiar (...) to modern life. This, the author thinks, is most of us. Narrowing down the scope of the tradition, the author draws from the history of Mexican philosophy in the 20th century, as it is at this time that Mexican philosophy comes into its own. The book begins with two short introductions, one is an introduction philosophy in Mexico, the other to Mexican philosophy. Here, readers are introduced to Alfonso de la Veracruz, who offered the first philosophy course in the Americas in 1540 in the monastery of a small town in Michoacán, Mexico. From there, it presents four main themes from Mexican philosophy that recur in the philosophical literature. The remainder of the book serves as a "guide" for living a better, more fulfilling life. The main characters in what the author considers an uncontroversial retelling of Mexican philosophy are Antonio Caso, Samuel Ramos, Emilio Uranga, Leopoldo Zea, Jorge Portilla, Rosario Castellanos, Elsa Cecilia Frost, and, of course, persons in the author's own life.

The objective of the present review on the evolution of Green Chemistry, since its emergence until 2016, aimed an integrated vision of its progress along the three phases of its development: emergence, divulgation and consolidation. The methodology involved the analysis of a selection of bibliography on the evolution of GC collected from issues of the ACS symposia series; editorials in specialized GC journals; and commemorative birthday papers/editorials of these journals and of the GC itself. The analysis allowed to identify and (...) discuss the characteristics and conceptions of GC agents about fundamental concepts and procedures, in order to visualize and better understand the state of knowledge and the subject areas that make up the field. The main alterations identified in the evolution of GC were: it acquired a better defined identity, with more participation of academy and increased scope; was progressively framed in sustainability; has been aspiring to a holistic frame and to a change on the nature of the innovation for its implementation, from incremental to transformative. The analysis suggests that for supporting expansion and consolidation of GC the following aspects deserve attention: full validation of chemical greenness by metrics; better characterization of the frontiers of GC research areas/themes; increased integration between academy and industry; and penetration in chemistry curricula. Its basic philosophy being the practice of a chemistry more focused on the environment preservation, GC means a new stage in nature and in the history of Chemistry. (shrink)

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.

Resumen: Este artículo sostiene que la regla en el mundo social es el cambio, en todas las escalas de tiempo, sin ciclos ni periodicidades. Por consiguiente, el tema que emerge inmediatamente es la irregularidad del mundo. Si esto es cierto, deben ser posibles unas ciencias sociales irregulares. El mejor antecedente para una idea semejante se encuentra en la comprensión del propio Mandelbrot acerca de los fractales y multifractales. Las ciencias sociales tratan radicalmente, de fenómenos irrepetibles, singulares. Estos han sido llamados (...) como eventos raros. De esta suerte, una nueva epistemología emerge y es posible. Al final se muestra que existen nexos fuertes entre las ciencias sociales con la biología y la ecología. Pero en ese punto, el texto termina abierto.: This paper claims that change is the rule in the social world, in all scales of time, without cycles or periodic dynamics. Hereafter, the topic that immediately arises is the irregularity of the world. If this is true, then irregular social sciences are to be possible. The best antecedent of such an idea is to be found in Mandelbrot’s own understanding of fractals and multifractals. Thus, the social sciences radically deal with phenomena that are in no way repeated, for they are singular. Such events have been called as rare events. In thus tenure, a brand-new epistemology arises and is possible. At the end, some connections between the social sciences and biology and ecology are depicted. That, however, is where this text ends and remains open. (shrink)

No cartesianismo contemporâneo, devido à retomada da teoria da livre criação das verdades eternas, alguns intérpretes trazem ao debate internacional um interessante viés interpretativo do pensamento de Descartes. Segundo eles, ao apresentar a indiferença da vontade como atributo de Deus, Descartes instaura uma concepção totalmente perigosa, da qual derivam a incompatibilidade entre a indiferença divina e o sistema cartesiano, deflagrando, enfim, um irracionalismo radical.

We obtain, for the first time, a modular many-valued semantics for combined logics, which is built directly from many-valued semantics for the logics being combined, by means of suitable universal operations over partial non-deterministic logical matrices. Our constructions preserve finite-valuedness in the context of multiple-conclusion logics, whereas, unsurprisingly, it may be lost in the context of single-conclusion logics. Besides illustrating our constructions over a wide range of examples, we also develop concrete applications of our semantic characterizations, namely regarding the semantics (...) of strengthening a given many-valued logic with additional axioms, the study of conditions under which a given logic may be seen as a combination of simpler syntactically defined fragments whose calculi can be obtained independently and put together to form a calculus for the whole logic, and also general conditions for decidability to be preserved by the combination mechanism.

Many experts have warned that environmental degradation is increasing the likelihood of future pandemics like COVID-19, as habitat loss and poaching increase close contact between wildlife and people. This fact has been framed as a reason to increase wildlife conservation efforts. We have many good reasons to step up conservation efforts, but arguments for doing so on the basis of pandemic prevention are rhetorically, ethically, and empricially flawed.

Cet article propose une interprétation de la philosophie de la Nouvelle Académie différente de celle qui a été défendue par J. Annas. Il nous semble que la prise en compte de l'ensemble des témoignages concernant cette école suggère une réalité plus complexe que celle que recouvre le concept de scepticisme, au moins dans sa version néopyrrhonienne. Nous croyons qu'Arcésilas et Carnéade n'ont pas délimité un Platon sceptique, mais qu'ils ont accepté à leur manière l'ensemble de l'héritage platonicien. La force de (...) la tradition apparaît donc plus forte dans l'histoire de l'Académie que ne l'admettent généralement les interprètes. The purpose of this article is to give an interpretation of the New Academy's philosophy quite different from the one defended by J. Annas. In our opinion the reading of the whole testimonies relating to this school suggests a greater complexity than what is embraced by the concept of skepticism, at least in its neopyrrhonian version. We believe that Arcesilas and Carneades, instead of confining Plato whithin the limits of skepticism, have accepted - in their own way - the whole Platonician legacy. Thus the burden of tradition seems more important in the history of the Academy than it is generally admitted. (shrink)

It is proposed that subconscious retro-predictions in conjunction with brain state update cycles are instrumental in the physiological generation of conscious sensations and perceptions, and in all abstract thought. In this paper the hypothesis is supported by conducting a detailed a re-evaluation of the self-referential statements in Set Theory and Formal Logic known as antinomies. This study concludes that the recursive behavior exhibited by abstract enigmas such as "Russell’s Paradox" is analogous to the oscillations typical of bistable perceptual phenomena.

The notion of stimulus meaning, a key notion for Quine's Indeterminacy of Translation thesis, has undergone an essentiaJ change fi'om the beginning of the nineties. Then, this essay offers an expository work oj this change (its origin and motivations) and its final result. Th~ main aim of this essay is to show the validity of the reasons that forced Quine to modify his stimulus meaning notion and the failure of its substitutes (global stimulus, stimulus range, and perceptual similarity) to solue (...) the problems they were thought to give an account of. Moreover, these new notions make the Indeterminacy Thesis, mainly the Inscrutability of Reference Thesis, face new problems and, if I'm right, unsolvable ones. (shrink)

We study the general problem of strengthening the logic of a given matrix with a set of axioms, using the idea of rexpansion. We obtain two characterization methods: a very general but not very effective one, and then an effective method which only applies under certain restrictions on the given semantics and the shape of the axioms. We show that this second method covers a myriad of examples in the literature. Finally, we illustrate how to obtain analytic multiple-conclusion calculi for (...) the resulting logics. (shrink)
