The main thesis defended in this paper is that Hildebrand’s distinction between what we could call quiddities—or “quasi-essences,” endowed with chaotic and accidental unity—and genuine essences possessing an intrinsically necessary unity, grounds the radical distinction between analytic and synthetic a priori knowledge. This thesis has not been expressly emphasized by Hildebrand himself. In order to prove it, we: (1) relate the three types of unities distinguished by Hildebrand with the three kinds of judgments discriminated by Kant; (2) outline what we (...) can call the “crux of empiricism”; (3) analyze four characteristic examples of synthetic a priori judgements; and (4) elaborate a provisional typology of synthetic a priori propositions, trying to include in it Hildebrand’s favorite examples.

¿Cuál es la mejor imagen para representar la actividad filosófica? García Morente analiza tres esculturas: Le penseur de Rodin, Il pensieroso de Miguel Ángel y la escultura de El doncel de Sigüenza que se encuentra en la catedral de esta ciudad. Esta última, afirma Morente, refleja mejor que ninguna otra la naturaleza de la filosofía. En este ensayo se rechaza esta opinión de Morente y se proponen otras dos representaciones de la actividad filosófica, en este caso pinturas, que simbolizan (...) más adecuadamente el acto de filosofar, entendido como un diálogo socrático inacabable.

La división de los deberes morales en estrictos y amplios se corresponde con la distinción entre las dos clases de contradicción que pueden darse al universalizar las máximas. Por tanto, su omisión dificul ta una correcta interpretación del imperativo categórico.

Popper acepta que es imposible realizar una falsación práctica definitiva, pero cree que esto no afecta a la posibilidad de una falsación en sentido lógico y, por tanto, no pone en cuestión el criterio de demarcación. Frente a esta convicción aquí se propone que la imposibilidad de efectuar una falsación definitiva modifica necesariamente la noción de demarcación de Popper.

Tras caracterizar brevemente el formalismo ético que constituye el núcleo de la ética de Kant y recordar la convicción kantiana de que el imperativo categórico no es sino la aclaración del principio moral que la razón vulgar prefilosófica posee, se intenta mostrar como algunas tesis que se siguen del sistema moral de Kant entran en contradicción con certezas de ese saber moral vulgar. Estas tesis son cuatro: la no existencia de voliciones indiferentes, la carencia de auténticos preceptos positivos que expresen (...) deberes y no sólo prohibiciones, la equivalente gravedad de todo acto indebido y la no aceptación de lo meritorio, pero no obligado.

In the Middle Age it was tried to show that índex of five predicables that Porfirio proposes in Isagoge was suitable and complete. More recently it is affirmed that chis índex is incomplete, and thal can add a new predicable that also Aristotle would have considered: the accidents per se.

El objeto de este trabajo es exponer la enseñanza de los comentarios neoplatónicos griegos sobre el carácter completo del catálogo aristotélico de las categorías en sí mismo considerado. Esta enseñanza puede contribuir a la clarificación del debate actual sobre el problema de la naturaleza de las categorías y su número. Se analizan y discuten los comentarios a las Categorias debidos a Porfirio, Dexipo, Ammonio, Simplicio, Olimpiodoro, Elías y Filopón.

Esta introducción presenta los estudios del volumen como respuestas a la primera de las tres preguntas fundamentales de la ontología: ¿Qué hay?, ¿Qué es el ser?, ¿Por qué hay algo y no más bien nada? A pesar de que la tercera cuestión ha sido considerada como la más originaria, la admiración de la que nace alcanza su plenitud cuando el filósofo se pregunta, además, por qué las cosas son así y no de otro modo. Pero esta nueva pregunta solo puede (...) surgir cuando el filósofo detiene su mirada ante la irreductible variedad de lo real, es decir, cuando se ocupa con los problemas fundamentales de la teoría de las categorías.

Nietzsche uses many of the arguments used by himself against metaphysics in general to criticize the Cartesian cogito. The affinity indicated by Descartes himself between cogito and conscience means that the study focuses on the Nietzschean analysis of the problem of conscience, paying special attention to its anthropological implications. Faced with Cartesian reasoncentrism, Nietzsche maintains that, given that conscience is not an entity removed from the natural world, it is possible to present a strictly naturalist anthropology, eliminating the need to (...) resort to dualist hypothesis drawn from metaphysics or theology.

Delimitando el problema mente-cerebro como específicamente moderno, diverso del de las relaciones cuerpo-alma, el autor realiza una fenomenología del darse de lo físico y de lo mental como pórtico necesario para indagar el tipo de relaciones que cabe concebir entre esos dos ámbitos fenoménicos. El recorrido de las diversas teorías se hace agrupándolas en dos enfoques generales: las teorías dualistas y las teorías monistas. A la exposición de cada una se acompañan las objeciones principales que cabe alzar contra ellas. Al (...) final del recorrido, el autor ofrece un argumento contra el materialismo monista, que, sin ser definitivo, parece abonar la mayor plausibilidad de la hipótesis dualista. (shrink)

We investigate whether age profiles of ethnobiological knowledge development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. Life history models predict complementary knowledge profiles developing across the lifespan for women and men as they experience changes in embodied capital and the needs of dependent offspring. We evaluate these predictions using an ethnobiological knowledge assessment tool developed for an off-grid pastoralist population known as Choyeros, from Baja California Sur, Mexico. Our results indicate that (...) while individuals acquire knowledge of most dangerous items and edible resources by early adulthood, knowledge of plants and animals relevant to the age and sex divided labor domains and ecologies (e.g., women’s house gardens, men’s herding activities in the wilderness) continues to develop into middle adulthood but to different degrees and at different rates for men and women. As the demands of offspring on parents accumulate with age, reproductive-aged adults continue to develop their knowledge to meet their children’s needs. After controlling for vision, our analysis indicates that many post-reproductive adults show the greatest ethnobiological knowledge. These findings extend our understanding of the evolved human life history by illustrating how changes in embodied capital and the needs of dependent offspring predict the development of men’s and women’s ethnobiological knowledge across the lifespan.

This article connects the insights of post-realist scholarship about radical indeterminacy and its consequences for the legitimacy of adjudication to the current legitimacy crisis of the international investment regime. In the past few years, numerous studies have exposed serious shortcomings in investment law and arbitration including procedural problems and the substantive asymmetry of the rights protected. These criticisms have prompted a broad consensus in favor of amending the international investment regime and multiple reform proposals have appeared that appeal to the (...) rule of law ideal as an instrument for increasing the acceptability of the international investment system. This article argues that the reliance of such proposals on jurisprudential approaches that fail to adequately accommodate the post-realist indeterminacy critique and take seriously the role of ideology in adjudication renders reform efforts unable to solve the legitimacy problems of the investment regime. The conclusions suggest the need to abandon implausible claims to depoliticization and face the methodological challenges posed by the promise of ideologically balanced assessments advanced by some rule of law theorists. The article finally points at the urgency to reform traditional approaches to doctrinal work in order to increase awareness of critical challenges and open up doctrinal methods to alternative methodological avenues.

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)

Atrial fibrillation is the most common cardiac arrhythmia in clinical practice. It often starts with asymptomatic and short episodes, which are difficult to detect without the assistance of automatic monitoring tools. The vast majority of methods proposed for this purpose are based on quantifying the irregular ventricular response during the arrhythmia. However, although AF totally alters the atrial activity reflected on the electrocardiogram, replacing stable P-waves by chaotic and time-variant fibrillatory waves, this information has still not been explored for automated (...) screening of AF. Hence, a pioneering AF detector based on quantifying the variability over time of the AA morphological pattern is here proposed. Results from two public reference databases have proven that the proposed method outperforms current state-of-the-art algorithms, reporting accuracy higher than 90%. A less false positive rate in the presence of other arrhythmias different from AF was also noticed. Finally, the combination of this algorithm with the classical analysis of RR series variability also yielded a promising trade-off between AF accuracy and detection delay. Indeed, this combination provided similar accuracy than RR-based methods, but with a significantly shorter delay of 10 beats. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anthropological Perspectives in Psychiatric NosologyJuan J. López-Ibor Jr. (bio) and María-Inés López-Ibor (bio)KeywordsDSM, etiology, Aristotelian causes, social dramasPsychiatry and clinical psychology, as we learn in this paper, are disciplines in need of an ontological perspective. Very few branches of contemporary learning share this characteristic. Probably only theoretical physic and theology—as the rest have long ago given up trying to define and understand the essence of their object, for example, (...) life in the case of biology or mind in psychology. Consequently, the paper by Pérez-Álvarez, Sass and García-Montes, “The Ontology of Mental Disorders in Constructivist Perspective,” (2008) should be welcomed and indeed included in the reading lists for trainees in psychiatry and clinical psychology.The authors propose an approach to the understanding of mental disorders that is extremely attractive and well articulated, and which also has practical implications for clinicians. It is not just another “philosophical divertimento” devoid of scientific and practical importance. Let us analyze the article in an orderly way.Less DsmThe authors of the target paper disapprove of the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III/IV approach to defining illnesses by starting from the symptoms that are present—on the grounds that this may lead clinicians to assume that their sole role is to identify, fight, and suppress the symptoms by whichever procedure. They propose an alternative that is dear to myself because it follows the path of the so-called “anthropological” psychiatry of Binswanger, von Gebsattel, Erwin Strauss, Zutt, López-Ibor, Sr., and others. In essence, this is a phenomenological approach to the meaning of mental diseases, one that emphasizes how the illness is revealed to the patient him- or herself.The target article’s criticism of DSM should be considered in the context of the abuses committed on its behalf. The DSM is not a textbook of psychiatric disorders, nor does it contain a definition of the diseases. The DSM does not tell what a disease is (Klerman et al. 1984)—something that is impossible with a classification system based on the manifestations of the diseases, the signs and symptoms. The DSM, as its title states, is just a diagnostic and statistical manual, which does not contain anything about the origin of [End Page 259] any disease nor an explanation of why it exists or what it means. The DSM is, in fact, just a tool to determine whether a disease is present, and therefore to facilitate communication between professionals and with other individuals, without saying anything about the disease’s aitia—a key term (associated with notions of essence as well as cause) to be discussed below. In theory, most clinicians should understand these limitations; it may be, however, that this is not really the case for many who read or use the DSM. In the world there are around 200,000 psychiatrists; since 1980 the number of DSM copies sold is in the order of several hundred thousand.The misuse of a classification system is even more noticeable in the International Classification of Diseases (ICD)-10 Research Version. The instructions for the use of this version recommend that the first step is to make an inventory of all the symptoms present, and then to construct a diagnosis based on them. This how all computer-assisted systems work. This procedure can, however, only be valid if the clinician has already reached a diagnostic conclusion by other means—a diagnosis then to be confirmed for research purposes. It may be that this is one of the reasons why the ICD-10 Research Version has almost never actually been used for research.Furthermore, the concept of symptoms in psychiatry applies only to organic mental disorders (Schneider 1959), conditions in which the patient’s attitude and way of experiencing the symptoms do not play the kind of role that they play in schizophrenia and other mental disorders. The quotation from the important paper by Sass and Parnas in this context is most appropriate. It is indeed that case that “subjective experience can play an important causal role in the progressive experiential transformations of a developing schizophrenic illness... (shrink)

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

Which is the best icon of philosophical activity? The Spanish philosopher Garcia Morente analyses three sculptures: Le penseur by Rodin, Il pensieroso by Michelangelo and a sculpture known as El Doncel de Siguenza, in the cathedral of this Castilian town. Morente asserts that the latest reflects better than anyone else the nature of philosophy. In this paper the Morente’s view is rejected and another two ways of representing the philosophical activity are suggested: two ancient paintings that represent more properly the (...) philosophical labour, understood as an unending Socratic dialogue.
