Aristóteles parece negar el estatuto ontológico de los artefactos que no serían sustancias. Se analizan los textos básicos al respecto y sus principales interpretaciones. Se discute la opinión de R. Katayama, para mostrar que acierta en remarcar la importancia de la separabilidad de los compuestos, pero se equivoca en la noción de separación. Se sostiene que las formas no son separables de sus compuestos tanto naturales como artefactos, pero los primeros poseen un tipo de separación de otras formas o especies (...) que no poseen los segundos y, por ello, son substancias. Aristotle seems to deny the ontological status of artifacts which are not substances. In this paper I discuss the basic regarding this topic and its main intepretations. I discuss R. Katayama's opinion to show that he is right to underline the importance of the trait of separation, but he is wrong regarding the the notion of separation. My thesis is that neither the forms of natural things nor those of artifacts are separable from the composites, but the former possess a different kind of separation from other forms or species, which the latter do not possess. Hence, the former are substances. (shrink)

El objetivo del trabajo consiste en revisar dos versiones del argumento que concibe a la averiguación de la verdad como un factor que confi ere legitimidad al ejercicio de la función jurisdiccional penal: la de Ferrajoli y la de Laudan. Se sostiene que su estudio minucioso puede proporcionar bases racionales para decidir sobre la conveniencia de suscribir un garantismo extremo o uno de carácter más mesurado. Esta decisión cobra relevancia en el contexto de la discusión acerca de cuáles son las (...) características más apropiadas de los modelos teóricos del proceso penal. (shrink)

El artículo revisa las aportaciones más trascendentes que Jordi Ferrer ha hecho a la tradición racionalista de la prueba jurídica y evalúa críticamente el limitado papel que, desde su óptica, le corresponde desempeñar a la epistemología en la discusión general sobre los estándares de prueba apropiados para las distintas ramas del derecho. Más específicamente, se analiza la irrelevancia que Ferrer parece atribuir a dicha disciplina –o el silencio que debe guardar–, respecto del establecimiento del estándar de prueba deseable en materia (...) penal. Se concede que, en efecto, le corresponde al pueblo tomar la decisión de qué estándar implementar. No obstante, se sostiene, ello no impide que la epistemología incida en el proceso de formación de dicha decisión mediante la realización de observaciones, el ofrecimiento de argumentos y la propuesta de metodologías adecuadas, con miras a que aquella se tome en un contexto mejor informado y sea lo más racional posible. Se ilustra esta posición haciendo referencia al proyecto de epistemología jurídica de Larry Laudan. (shrink)

Purpose This study aims to understand the allure and danger of fake news in social media environments and propose a theoretical model of the phenomenon. Design/methodology/approach This qualitative research study used the uses and gratifications theory approach to analyze how and why people used social media during the 2016 US presidential election. Findings The thematic analysis revealed people were gratified after using social media to connect with friends and family and to gather and share information and after using it as (...) a vehicle of expression. Participants found a significant number of fake news stories on social media during the 2016 US presidential election. Participants tried to differentiate between fake news and real news using fact-checking websites and news sources and interacted with the social media users who posted fake news and became part of the echo chamber. Behaviors like these emerged in the analysis that could not be completely explained by UGT and required further exploration which resulted in a model that became the core of this study. Research limitations/implications This is a small-scale exploratory study with eight diverse participants, findings should not be generalized to larger populations. Time-specific self-reporting of information from social media and fake news during the 2016 US presidential election. Upgrading public policies related to social media is recommended in the study, contributing to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Practical implications Upgrade in public policies related to social media is recommended in the study and contributes to burgeoning policy discussions and provides recommendations for both purveyors of social media and public policymakers. Social implications Social media users are spending increased time on their preferred platforms. This study increases the understanding of the nature, function and transformation of virtual social media environments and their effects on real individuals, cultures and societies.What is original/of value about the paper?This exploratory study establishes the foundation on which to expand research in the area of social media use and fake news. Originality/value This exploratory study establishes the foundation to expand research in the area of social media use and fake news. (shrink)

There are many real-world applications like healthcare systems, job monitoring, well-being and personal fitness tracking, monitoring of elderly and frail people, assessment of rehabilitation and follow-up treatments, affording Fall Detection (FD) and ADL (Activity of Daily Living) identification, separately or even at a time. However, the two main drawbacks of these solutions are that most of the times, the devices deployed are obtrusive (devices worn on not quite common parts of the body like neck, waist and ankle) and the poor (...) battery life. Thus, this work proposes a low-power classification algorithm based on an Ensemble of KNN and K-Means algorithms (EKMeans) to identify Falls and High-Intensity ADL events such as running, jogging and climbing up stairs. The input of EKMeans are triaxial accelerometer data gathered from wrist-wearable devices. The proposal will be validated on the Fall&ADL publicly available datasets UMAFall, UCIFall and FallAllD, considering two kinds of activity labelling: Two-Class and Multi-Class. An exhaustive comparative study between our proposal, and the baseline algorithms KNN and a feed-forward Neural Network (NN) is deployed, where EKMeans outperformed clearly the Specificity (ADL classification) of the KNN and NN for the three datasets. Finally, a comparative battery consumption study has been included deploying the analyzed algorithms in a WearOS smartwatch, where EKMeans drains the battery from 100% to 0% in 27.45 hours, saving 5% and 21% concerning KNN and NN, respectively. Keywords: Human Activity Recognition, ADL Identification, Fall Detection TS Clustering, TS Classification, Wearable Devices, Low-Power HAR. (shrink)

This paper addresses a variant of the job shop scheduling problem with total tardiness minimization where task durations and due dates are uncertain. This uncertainty is modelled with intervals. Different ranking methods for intervals are considered and embedded into a genetic algorithm. A new robustness measure is proposed to compare the different ranking methods and assess their capacity to predict ‘expected delays’ of jobs. Experimental results show that dealing with uncertainty during the optimization process yields more robust solutions. A sensitivity (...) analysis also shows that the robustness of the solutions given by the solving method increases when the uncertainty grows. (shrink)

The main objective of this research is to identify the current panorama of scientific production associated with governance in university institutions. A bibliometric analysis was developed in Scopus using R Core Team 2022-Bibliometrix and Vosviewer software. The results highlight the countries with the highest productivity in the topic of study, with the most representative authors favoring the understanding of governance. The main thematic clusters stand out. It recognizes the role of university governance and its migration to direct spaces and the (...) transition from a face-to-face model. (shrink)

En el libro V de la República Platón intenta distinguir a los verdaderos filósofos de un grupo de personajes que son solo parecidos a los filósofos, pero que en realidad no lo son. Platón utiliza diferentes términos para referirse a estos pseudo-filósofos pero el más recurrente es el de philotheámones (φιλοθεάμονες). Los estudiosos de Platón han tenido muy diversas interpretaciones sobre la identidad de estos personajes. En este trabajo defiendo que dentro del grupo en cuestión están los sofistas, una interpretación (...) cuya intuición principal fue defendida por Vegetti (2000) pero criticada recientemente por Meinwald (2017). Aquí ofrezco tanto razones textuales como filosóficas y contextuales a favor de esta interpretación. (shrink)

I discuss Aristotle’s opening argument against Platonic Forms in _Metaphysics_ A.9, ‘the Razor’, which criticizes the introduction of Forms on the basis of an analogy with a hypothetical case of counting things. I argue for a new interpretation of this argument, and show that it involves two interesting objections against the introduction of Forms as formal causes: one concerns the completeness and the other the adequacy of such an explanatory project.

We outline a theory of the cognitive role of belief in absolute necessity that is normative and intended to be metaphysically neutral. We take this theory to be unique in scope since it addresses simultaneously the questions of how such belief is (properly) acquired and of how it is (properly) manifest. The acquisition and manifestation conditions for belief in absolute necessity are given univocally, in terms of complex higher-order attitudes involving two distinct kinds of supposition (A-supposing and C-supposing). It is (...) subsequently argued that the proposed acquisition and manifestation conditions are rationally interdependent, and that such harmony affords explanations of connections between different facets of belief in necessity that otherwise remain mysterious.

Republic 596a introduces a One over Many principle that has traditionally been considered as an argument for the existence of Forms, according to which, one Form should be posited for each like-named plurality. This interpretation was challenged by (Smith, J. A. 1917. “General Relative Clauses in Greek.” Classical Review 31: 69–71.), who interpreted it rather as a statement that each Form is unique and correlated to a plurality of things that have the same name as it. (Sedley, D. 2013. “Plato (...) and the One-over-Many Principle”, in Chiaradonna & Galluzzo 2013, 113–37.) has offered a forceful defence of Smith’s interpretation. I argue that Sedley’s defence fails and that the traditional interpretation should be preferred. (shrink)

In the first argument of Metaphysics Μ.2 against the Platonist introduction of separate mathematical objects, Aristotle purports to show that positing separate geometrical objects to explain geometrical facts generates an ‘absurd accumulation’ of geometrical objects. Interpretations of the argument have varied widely. I distinguish between two types of interpretation, corrective and non-corrective interpretations. Here I defend a new, and more systematic, non-corrective interpretation that takes the argument as a serious and very interesting challenge to the Platonist.

In this paper I examine Crispin Wright's modal anti-realism as based on the availability of a certain attitude of Caution towards judgements of necessity. I think that Wright's account should be attractive in several ways for modal theorists with an anti-realist bend. However, the attitude of Caution to which it appeals has attracted some controversy. Wright himself has later come to doubt whether Caution is ultimately coherent. Here I first address Wright's worries concerning the coherence of Caution and show that (...) they are unfounded. But then I argue that although the attitude of Caution is coherent, it cannot provide a suitable basis for a non-eliminativist account of necessity. I offer two different objections against Caution. I argue that Wright's appeal to Caution, if successful, would show not only that modal judgement is non-objective but also that it is dispensable. Thus, I claim that appeal to Caution would seem to serve more as a threat against a non-eliminativist account of necessity, rather than as a potential adequate basis for it. However, I argue that Wright's appeal to Caution is unsuccessful, for there is no genuine Caution: Caution is a mere verbal attitude. (shrink)

Aristotle formulates in _Metaphysics_ M.9 an aporia about Forms, according to which, those who introduce Forms make them universal substances and, at the same time, separate entities and, hence, particulars. But, he claims, it is not possible that both attributes, being a universal and being a particular, inhere in the same thing. The interpretation that scholars have offered of this objection is external, in that they hold that it derives from Aristotle’s own conception of separation: only what is particular is (...) separate. Here I defend an internal interpretation which claims that the objection derives from an assumption about the explanatory role of Forms that Aristotle attributes to the Platonists. (shrink)

En Metafísica M.2 Aristóteles desarrolla diversas objeciones en contra de la introducción platónica de objetos matemáticos como substancias no-sensibles, separadas de las sensibles. Su primera objeción es de carácter doble. En primer lugar, Aristóteles argumenta que la postulación de objetos geométricos separados produce una acumulación absurda. En segundo lugar, sugiere que este argumento geométrico se puede extender al caso de las unidades y los números. En este trabajo me ocupo de explicar esta extensión aritmética. Los especialistas han interpretado esta extensión (...) de una manera que denomino “maximalista”. Aquí defiendo una interpretación distinta, “minimalista”. (shrink)

En este trabajo examino la “elección imposible” que Sócrates le plantea a Teeteto y que parece consistir en elegir entre: aceptar (a) que el juicio falso es imposible, o (b) que es posible conocer y no conocer el mismo objeto (Teeteto 196c7-d2). De acuerdo con la interpretación tradicional de esta elección, Sócrates afirma que es necesario aceptar una de las dos opciones: (b). En consecuencia, Sócrates desarrollaría el Aviario como un modelo de explicación del error en el que es posible (...) conocer y no conocer lo mismo. Aquí argumento en contra de esta lectura. Según mi interpretación, lo que dice Sócrates es que se deben rechazar los dos términos de la “elección imposible”, (a) y (b), y, por ende, el Aviario presenta un modelo en el que el juicio falso es posible sin tener que aceptar que es posible conocer y no conocer lo mismo.

Under what conditions would it be paradoxical to consider the possibility of false judgment? Here we claim that in the initial puzzle of Theaetetus 187e5–188c9, where Plato investigates the question of what could psychologically cause a false judgment, the paradoxical nature of this question derives from certain constraints and restrictions about causal explanation, in particular, from the metaphysical principle that opposites cannot cause opposites. Contrary to all previous interpretations, this metaphysical approach does not attribute to Plato any controversial epistemological assumptions (...) and fits better with the text and its role within the dialectic of the dialogue.

En este trabajo realizo un examen crítico del reciente libro de Silvana Gabriela Di Camillo sobre la crítica de Aristóteles a la teoría platónica de las Ideas. El libro de Di Camillo es un trabajo muy serio cuya lectura recomiendo ampliamente. Sin embargo, considero que cuatro de las principales tesis que la autora defiende tienen varias dificultades y mi objetivo aquí es presentar argumentos detallados en contra de ellas: la interpretación de la distinción entre argumentos más y menos rigurosos del (...) tratado Sobre las Ideas; la tesis de que la separación es el blanco esencial de las críticas aristotélicas a las Ideas; la interpretación de las opciones que Platón tiene para responder al argumento del tercer hombre, y la tesis de que la separación de las Ideas debe entenderse como homonimia.

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

Some philosophers think that anti-realism about de re necessity entails anti-realism about the individuation and identity of objects. In this paper I address one argument for this view, due to Sidelle, according to which the only way in which a de re modal conventionalist can avoid being refuted by a well-known argument based on the contingency of conventions is by also accepting conventionalism about objects. I show that Sidelle’s argument is not successful and, in this way, I also show that (...) the combination of de re modal anti-realism and realism about objects is at least not threatened from this direction.

The majority of people show persistent poor performance in reasoning about “stock-flow problems” in the laboratory. An important example is the failure to understand the relationship between the “stock” of CO2 in the atmosphere, the “inflow” via anthropogenic CO2 emissions, and the “outflow” via natural CO2 absorption. This study addresses potential causes of reasoning failures in the CO2 accumulation problem and reports two experiments involving a simple re-framing of the task as managing an analogous financial budget. In Experiment 1 a (...) financial version of the task that required participants to think in terms of controlling debt demonstrated significant improvements compared to a standard CO2 accumulation problem. Experiment 2, in which participants were invited to think about managing savings, suggested that this improvement was fortuitous and coincidental rather than due to a fundamental change in understanding the stock-flow relationships. The role of graphical information in aiding or abetting stock-flow reasoning was also explored in both experiments, with the results suggesting that graphs do not always assist understanding. The potential for leveraging the kind of reasoning exhibited in such tasks in an effort to change people's willingness to reduce CO2 emissions is briefly discussed. (shrink)

Según la versión estándar del juego de la imitación, la determinación del sexo de los participantes no desempeña ningún papel en el testeo de la inteligencia de máquina. Desafortunadamente, tal simplificación soslaya la teoría de la mente que fundamenta dicho juego.

En efecto, tal como sostengo, la determinación del sexo de los participantes no debe obviarse: la mente de una mujer y su (...) inteligencia son imitables y no dependen de realización física específica. Esto ocurre porque el funcionalismo de Turing supone un vínculo entre imitación, engaño y aprendizaje, tres claves para que el proyecto de la Inteligencia Artificial tenga éxito. (shrink)

Background: Authors are required to describe in their manuscripts ethical approval from an appropriate committee and how consent was obtained from participants when research involves human participants.Objective: To assess the reporting of these protections for several study designs in general medical journals.Design: A consecutive series of research papers published in the Annals of Internal Medicine, BMJ, JAMA, Lancet and The New England Journal of Medicine between February and May 2003 were reviewed for the reporting of ethical approval and patient consent. (...) Ethical approval, name of approving committee, type of consent, data source and whether the study used data collected as part of a study reported elsewhere were recorded. Differences in failure to report approval and consent by study design, journal and vulnerable study population were evaluated using multivariable logistic regression.Results: Ethical approval and consent were not mentioned in 31% and 47% of manuscripts, respectively. 88 papers failed to report both approval and consent. Failure to mention ethical approval or consent was significantly more likely in all study designs than in randomised controlled trials . Failure to mention approval was most common in the BMJ and was significantly more likely than in The New England Journal of Medicine. Failure to mention consent was most common in the BMJ and was significantly more likely than in all other journals. No significant differences in approval or consent were found when comparing studies of vulnerable and non-vulnerable participants.Conclusion: The reporting of ethical approval and consent in RCTs has improved, but journals are less good at reporting this information for other study designs. Journals should publish this information for all research on human participants. (shrink)
