El tema vertebrador como se indica en el título es el sentido de la vida. Se ofrece una serie de reflexiones sobre la relación de la persona con la matematización de la cultura. El conocimiento científico del mundo no es banal, sino que a partir de él la persona en su «voluntad de sentido» mira a esa realidad con la que interactúa. Adentrarnos en el significado de algunos fenómenos matemáticostecnológicos relacionados con la inteligencia artificial, captar los mensajes sociales que se (...) producen y penetrar en su sentido profundo puede ofrecernos claves para la comprensión (y auto-comprensión) de la persona en su estar en la sociedad actual.

En estos últimos años es reconocida la influencia de la dimensión emocional en el desarrollo del aprendizaje en el aula. Sin embargo, parece necesario un mayor desarrollo de los descriptores básicos: actitudes, emociones, creencias y valores en disciplinas concretas. El artículo aborda el tema de los valores y actitudes de las Matemáticas y de forma específica el valor de la belleza. Se argumenta sobre la importancia del juicio estético como una componente importante en el buen resolutor de problemas, explicitando sus (...) implicaciones para la educación matemática de los estudiantes.

The aim of the present study is to analyze individual differences in academic self-efficacy within a population of Unaccompanied Foreign Minors from the European cities of Ceuta and Melilla. Variables describing educational level and length of stay were considered in a sample of 377 individuals being cared for in different youth centers. Of these, 63.4% belonged to the group who had stayed at the center for less than 9 months and 36.6% reported a length of stay of more than 9 (...) months. The age of participants ranged between 8 and 17 years old. Once the quality parameters of the instrument were elaborated, reliability and validity was confirmed through Confirmatory Factor Analysis using Structural Equation Modeling methodology. Data collection was then initiated. The results overall indicate that 87.6% of those who completed the questionnaire reported a higher level of self-efficacy with regards to working with any classmate, whilst at the same time seeing themselves as capable of achieving good marks. ANOVA results indicated significant differences with respect to educational level and length of stay. In this regard, students who had received professional training and had been at the Center for more than 9 months, were the ones who developed greater academic self-efficacy for spending more time working when tasks were judged to be difficult. The results obtained demonstrate that any intervention will be positive as long as it promotes different institutions to develop strategies that cater to a length of stay of more than 9 months and target education, academic self-efficacy, socialization and strengthening the future workforce. Such interventions can be directed through new European, Spanish or local level policies. It is clear that institutions still have a lot of work left to do. (shrink)

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

El objetivo de esta investigación es determinar si existe influencia en los alumnos al elegir una carrera profesional por parte de los padres al manifestar estos un deseo diferido por obtener un título profesional y establecer el grado de satisfacción de los alumnos con su carrera elegida. La investigación se realizó dos etapas, la primera detecta si existe el deseo diferido de los padres por obtener un título profesional y la influencia de este sobre los alumnos. La segunda midió la (...) satisfacción de los alumnos con la carrera y el grado de influencia de los padres. El 79.31% de los padres presentan el deseo diferido por obtener un título profesional, de los cuales el 67% de ellos a influenciado alguno de sus hijos con su deseo, la satisfacción de los alumnos con su carrera está directamente relacionada con la influencia de los padres y con el semestre que cursa. Se concluye que el deseo diferido de los padres por obtener un título profesional existe en la mayoría de ellos y este se refleja en sus consejos para la selección de la carrera por parte del alumno y su grado de satisfacción.

​This paper examines the life and work of the Novohispanic philosopher Sor Juana Inés de la Cruz, who used a great deal of irony to respond to what, we argue, were gender-based microaggressions in 17th century New Spain. The case of Sor Juana is particularly interesting not only because it suggests that microaggressions are not the product of our time, as has been suggested in the literature, but also because it reveals some of the advantages as well as limitations (...) of using irony when one is subject to microaggression. The case of Sor Juana also provides insights regarding the difficulties of using irony to address microaggressions that take place in the classroom. (shrink)

Despite recent efforts by the Artificial Intelligence (AI) community to move towards standardised procedures for documenting models, methods, systems or datasets, there is currently no methodology focused on use cases aligned with the risk-based approach of the European AI Act (AI Act). In this paper, we propose a new framework for the documentation of use cases that we call use case cards, based on the use case modelling included in the Unified Markup Language (UML) standard. Unlike other documentation methodologies, we (...) focus on the intended purpose and operational use of an AI system. It consists of two main parts: firstly, a UML-based template, tailored to allow implicitly assessing the risk level of the AI system and defining relevant requirements, and secondly, a supporting UML diagram designed to provide information about the system-user interactions and relationships. The proposed framework is the result of a co-design process involving a relevant team of EU policy experts and scientists. We have validated our proposal with 11 experts with different backgrounds and a reasonable knowledge of the AI Act as a prerequisite. We provide the 5 use case cards used in the co-design and validation process. Use case cards allows framing and contextualising use cases in an effective way, and we hope this methodology can be a useful tool for policy makers and providers for documenting use cases, assessing the risk level, adapting the different requirements and building a catalogue of existing usages of AI.

It has often been noted that Leo Strauss developed his understanding of political philosophy through a critical engagement with Heidegger. Yet most analyses focus on Strauss’s American works while neglecting his earlier response during the crisis years of the Weimar Republic. The article seeks to overcome this limitation by ‘deconstructing’ Strauss’s American definitions of political philosophy in light of both his Weimar understanding of politische Wissenschaft and his 1922 discovery of Heidegger’s Aristotle. I argue that Strauss’s conception of political philosophy (...) originated in Heidegger’s subversion of the traditional distinction between theory and praxis. I thus propose a way to read Strauss from the start following his own changing views of that distinction. (shrink)

This work documents the ethical dilemmas faced by anthropologists and researchers in general when investigating Amerindian communities.

Based on the theoretical reconstruction of neglected post-WWI writings and political action of W. E. B. Du Bois, this volume offers a normative account of transnational cosmopolitanism. Pointing out the limitations of Kant's cosmopolitanism through a novel contextual account of Perpetual Peace, Transnational Cosmopolitanism shows how these limits remain in neo-Kantian scholarship. Inés Valdez's framework overcomes these limitations in a methodologically unique way, taking Du Bois's writings and his coalitional political action both as text that should inform our theorization (...) and normative insights. The cosmopolitanism proposed in this work is an original contribution that questions the contemporary currency of Kant's canonical approach and enlists overlooked resources to radicalize, democratize, and transnationalize cosmopolitanism.

IntroductionStress is associated with disease and reduced leukocyte telomere length. The objective of this research is to determine if self-perceived stress is associated with telomere length in Costa Rican adults and the gender differences in this association. Findings may help explain how some populations in apparent socioeconomic disadvantage and with limited access to specialized medical services have a remarkably high life expectancy.MethodologyData come from the pre-retirement cohort of the Costa Rican Longevity and Healthy Aging Study, a population based survey conducted (...) in the households to 2,327 adults aged 53 to 66 years. The DNA to measure LTL was extracted from blood cells in laboratories of the University of Costa Rica whereas the Blackburn laboratory at the University of California performed the telomere length measurement applying the quantitative polymerase chain reaction. The relationship between telomere length and perceived stress was measured using least-squares multiple regression. Perceived stress was measured by a set of questions about family, job, finances and, health reasons to be stressed. Models included the control variables: age and sex of the participant, whether he or she resides in the Nicoya area, a “blue zone” known for its high longevity, and the aforementioned sociodemographic, health and lifestyles characteristics.ResultsStress perception and LTL are significantly different by sex. Women perceived higher stress levels than men in almost all aspects studied, except work. Women have significantly longer telomeres. Shorter telomeres are significantly associated with caregiving stress in men and with parental health concerns in women. Counter-intuitive telomere lengthenings were observed among women who feel stressed about caring for family members; and among men who feel stressed due to their family relationships as well as concerns about their own health.DiscussionResults confirm that people with self-perceived stress due to caregiving or health issues have shorter telomeres. The relationship between stress and telomere length differs between men and women. Gender relations exert a strong modifier effect on the relationship between stress and LTL: gender is related to perceived stress, telomere length, and apparently also to the way stress and LTL are related.

This is the first publication on complete and stand alone arithmetization of bivalent logic.

We propose a semiotic framework to underpin a posthumanist philosophy of education, as contrasted to technological determinism. A recent approach to educational processes as semiotic phenomena lends itself as a philosophy to understand the current interplay between education and technology. This view is aligned with the transhumanist movement to defend techno-scientific progress as fundamental to human development. Particularly, we adopt a semiotic approach to education to tackle certain tensions in current debates on the human. Transhumanism scholars share the optimistic belief (...) that there is no limit to how the ethical use of technology can help alleviate suffering and increase our health and wisdom. From this perspective, it appears possible to acquire capacities that require rethinking the notion of human altogether. For others, this undermining of essentialist concepts of humanity entails serious risks, especially related to ethical egalitarianism. We adopte the perspective of edusemiotics, a framework that brings together semiotics, educational theory and philosophy of education. As a theoretical-practical framework, edusemiotics affords a hermeneutic and semiotic method for our approach. Peirce’s logic of signs is used to analyze socio- educational interactions as environmental. We observe two lines of thought. On the one hand, technological transhumanism enhances Cartesian mind–body dualism. On the other hand, philosophical posthumanism seeks to overcome this dichotomy. The former proposal construes human transformation as an artifactualization derived from techno-scientific enhancements. The latter position proposes an integrative posthumanism, capable not only to include edusemiotic theory but also to rethink the concept of learning as mutual to that of human. (shrink)

The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its corollary process theory, active inference; and (2) if so, to assess which philosophical stance - in relation to the ontological and epistemological status of representations - is most appropriate. We focus on non-realist (deflationary and fictionalist-instrumentalist) approaches. We consider a deflationary account of mental representation, according to which the explanatorily relevant contents of neural (...) representations are mathematical, rather than cognitive, and a fictionalist or instrumentalist account, according to which representations are scientifically useful fictions that serve explanatory (and other) aims. After reviewing the free-energy principle and active inference, we argue that the model of adaptive phenotypes under the free-energy principle can be used to furnish a formal semantics, enabling us to assign semantic content to specific phenotypic states (the internal states of a Markovian system that exists far from equilibrium). We propose a modified fictionalist account: an organism-centered fictionalism or instrumentalism. We argue that, under the free-energy principle, pursuing even a deflationary account of the content of neural representations licenses the appeal to the kind of semantic content involved in the aboutness or intentionality of cognitive systems; our position is thus coherent with, but rests on distinct assumptions from, the realist position. We argue that the free-energy principle thereby explains the aboutness or intentionality in living systems and hence their capacity to parse their sensory stream using an ontology or set of semantic factors.

I defend the hypothesis that the semantic paradoxes, the paradoxes about collections, and the sorites paradoxes, are all paradoxes of reference fixing: they show that certain conventionally adopted and otherwise functional reference-fixing principles cannot provide consistent assignments of reference to certain relevant expressions in paradoxical cases. I note that the hypothesis has interesting implications concerning the idea of a unified account of the semantic, collection and sorites paradoxes, as well as about the explanation of their “recalcitrance”. I also note that (...) it does not necessarily imply that one should not expect the sometimes hoped for “unique” solution to a paradox of these kinds. (shrink)

“Hay momentos en la vida en los que la cuestión de saber si se puede pensar distinto de como se piensa o percibir distinto de como se ve es indispensable para seguir contemplando o reflexionando” (Foucault, 2003, p. 8). Esta declaración foucaultiana es la que impulsa la voluntad genealógica que presenta este ensayo, así como su pretensión proyectiva para pensar hoy la educación. El momento filosófico crítico consiste en volver sobre las prácticas que día a día llevamos a cabo y (...) configuran nuestras vidas y nuestras instituciones. Este es necesario para realimentar y reorientar la savia de las instituciones, y especialmente la savia de nuestras instituciones académicas, suelo en el cual se teje la sustancia ética que posteriormente dará lugar a la articulación social. Si se aplica el elemento crítico que la actividad filosófica supone a la experiencia de la educación, entendiendo por ella la correlación dentro de una cultura entre campos de saber, tipos de normatividad y formas de subjetividad, podemos preguntarnos: qué es la educación y qué función desempeña hoy con respecto al ejercicio mismo del pensamiento en un contexto atravesado por las nuevas tecnologías y la IA.

Explorar la posibilidad de una nueva micropolítica crítica del signo a partir de Foucault, inspirada en la genealogía nietzscheana, y examinar las políticas y estrategias de alfabetización mediática e informacional necesarias para desarrollar competencias digitales en la transformación del ecosistema mediático es una tarea fundamental del quehacer filosófico actual. La pregunta por la posibilidad de la verdad retorna en un contexto en el que el pluralismo semiótico y la conducción mediática son dos elementos que rigen y ordenan la sociedad actual, (...) sociedad que se caracteriza por la abundancia de información y la omnipresencia de los medios de comunicación como tecnologías de poder. Desgranar su significado y vínculo nos conduce directamente al estudio del poder y el signo en relación con los efectos de la verdad de la posverdad. En este marco conceptual, la obra de Foucault proporciona herramientas teóricas valiosas para afrontar esta problemática. (shrink)

La sociedad del siglo XXI ha sufrido una mutación histórica en lo que respecta a los métodos de producción y los impactos derivados de la generación de información. Este período se caracteriza por su inmersión en el entorno digital, donde los individuos, como ciudadanos, se encuentran bajo la manipulación, por un lado, de sus datos mediante técnicas de vigilancia y, por otros, expuestos a cámaras de resonancia mediática. Este panorama plantea desafíos significativos en cuanto a la manera en que interactúan (...) con la información y cómo esta afecta sus vidas.

Quien enseña sin emancipar no solo embrutece, predicaba Joseph Jacotot, sino que también adoctrina. Pasado un siglo y medio desde entonces, el filósofo y esteta francés emérito de la Universidad de París VIII y European Graduate School Jacques Rancière, en un ejercicio característico de la filosofía de la educación, publica en 1987 El maestro ignorante a partir de la experiencia de Jacotot.

Concern about air-quality in urban areas has led to the implementation of Low Emission Zones as one of many other initiatives to control it. Recently in Spain, the enactment of a law made this mandatory for cities with a population larger than 50k inhabitants. The delimitation of these areas is not without controversy because of possible negative economic and social impacts. Therefore, clear assessments of how these initiatives decrease pollutant concentrations are to be provided. Madrid Central is a major initiative (...) of Madrid city council for reducing motor traffic and the associated air pollution in the city centre. This Low Emission Zone starts at the end of 2018, but the first fully-operational period corresponds to the second quarter of 2019. In this work, a methodology based on the Gaussian Process to analyse the evolution of Nitrogen Dioxide inside Madrid Central is undertaken. A Gaussian Process is a stochastic process suitable for interpretable model selection and predictions. Due to its probabilistic nature it provides error estimation at predictions. After the activation of Madrid Central, a relevant reduction of Nitrogen Dioxide has been observed. However, the role of the meteorology during this period must be ascertained to correctly evaluate the role of the activation of the Low Emission Zone against a prone weather. In this work, a model based on the Gaussian Process is trained with meteorological information to predict the concentration of Nitrogen Dioxide at Madrid Central, $[NO_{2}]$. This probabilistic description allows extracting statistical information on the reduction affected by the meteorological scenario and separately by the Madrid Central activation. (shrink)

This article presents an analysis of contractual relations in sport from the standpoint of the Croatian legislative system. Due to the complexity of the subject matter, the author considers only a small fragment of it - the significance and the role of sport in Croatian society and the law of contracts „as a cornerstone on which „sports law“ has been built and which is of primary importance in most areas where there is an interface between sport and the law, irrespective (...) of whether the sport is being played at an elite level or at a more humble one“. Bearing in mind the limited extent of this article, the autor tries to provide some clarifications and some guidance on how to deal with the designation and the determination of the applicable law for contracts in the sporting context. Considering that there are different legal regimes which may come into play with regard to the designation of the law applicable to contracts in the sporting context, the author first presents the determination of the applicable law according to the Rome I Regulation and then according to the Croatian Arbitration Act, Swiss Private International Law Act and the CAS Code of Sports-related Arbitration, as the most common in sports practice. Then, the author deals with contracts concluded with minor athletes and the determination of the law applicable to some preliminary questions. Finally, the author presents her perception of the problems encountered and some suggestions for the improvement of the existing legal framework. (shrink)

BackgroundThis article aims to contribute to a better conceptualization of pain and suffering by providing non-essential and non-naturalistic definitions of both phenomena. Contributions of classical evidence-based medicine, the humanistic turn in medicine, as well as the phenomenology and narrative theories of suffering and pain, together with certain conceptions of the person beyond them are critically discussed with such purpose.MethodsA philosophical methodology is used, based on the review of existent literature on the topic and the argumentation in favor of what are (...) found as better definitions of suffering and pain.ResultsPain can be described in neurological terms but cognitive awareness, interpretation, behavioral dispositions, as well as cultural and educational factors have a decisive influence on pain perception. Suffering is proposed to be defined as an unpleasant or even anguishing experience, severely affecting a person at a psychophysical and existential level. Pain and suffering are considered unpleasant. However, the provided definitions neither include the idea that pain and suffering can attack and even destroy the self nor the idea that they can constructively expand the self; both perspectives can b e equally useful for managing pain and suffering, but they are not defining features of the same. Including the existential dimension in the definition of suffering highlights the relevance of suffering in life and its effect on one’s own attachment to the world. An understanding of pain and suffering life experiences is proposed, meaning that they are considered aspects of a person’s life, and the self is the ever-changing sum of these experiences.ConclusionsThe provided definitions will be useful to the identification of pain and suffering, to the discussion of how to relieve them, and to a better understanding of how they are expressed and experienced. They lay the groundwork for further research in all these areas, with the twofold aim of a) avoiding epistemological mistakes and moral injustices, and b) highlighting the limitations of medicine in the treatment of suffering and pain.

How was historical time conceptualized in intellectual cultures diverging from the competitive opposition of "Old" and "New"? This book introduces a broad panorama of 18th-century Central European scholarship in its institutional and epistemological.

Admiration and adoration have been considered as emotions with the power to change people, yet our knowledge of the specific nature and function of these emotions is quite limited. From an interdisciplinary perspective, we present a prototype approach to admiration and what has variously been labelled adoration, worship, or reverence. Both admiration and adoration contribute to the formation of personal and collective ideals, values, and identities, but their workings differ. We offer a detailed theoretical account of commonalities and differences in (...) the appraisal patterns and action tendencies associated with the two emotions. This analysis reveals that admiration motivates the internalisation and emulation of ideals embodied by an outstanding role model. Adoration motivates adherence to the teachings and expectations of a meaning maker and benefactor perceived as superhuman or sacred. Thus, the primary function of admiration is to promote individual learning and change, whereas adoration primarily serves to bind communities together. (shrink)

In this paper, I respond to what I have called an epistemological objection to a dialetheist approach to the doctrine of the Incarnation, of which one example is Beall’s contradictory Christ. I discuss Anderson’s book Paradox in Christian theology, in which the author claims to account for the rationality of the doctrine of the Incarnation as a merely apparently contradictory doctrine, and I present my model, based on Anderson’s model, according to which the doctrine has the possibility to be rational (...) by understanding it as genuinely contradictory. I show that this model fits perfectly well with the criteria that, according to Anderson, any model for the rationality of a paradoxical doctrine should meet. Beall does not address the problem of the rationality of the doctrine in his works about the contradictory Christ, and he asserts that he is not interested in it. However, I think that if he wants to make his theory more robust, less suspicious, and more convincing for theologians, philosophers, and ordinary people, he should consider this problem. (shrink)

This article proposes a method for the semi-automatic extraction of resemblance metaphor terms from a manually annotated corpus of marine biology texts in English and Spanish. The corpus was first searched for target domain terms as well as for lexical markers indicative of metaphors. The combination of these search strategies for metaphor extraction resulted in a set of English-Spanish term pairs. After analysing and comparing these metaphor candidates, a quantitative analysis provided comparative statistical data regarding marine biology metaphor. Finally, the (...) metaphorical nature of marine biology terms was verified in three ways. The first verification strategy entailed an adapted version of the Metaphor Identification Procedure (CitationPragglejaz Group, 2007). The second involved the analysis of contextual data extracted from the corpus, and the third involved the analysis of visual images from an online marine biology database and from the Google search engine.

This edited book deepens the engagement between 21st century philosophy of mind and the emerging technologies which are transforming our environment. Many new technologies appear to have important implications for the human mind, the nature of our cognition, our sense of identity and even perhaps what we think human beings are. They prompt questions such as: Would an uploaded mind be 'me'? Does our reliance on smart phones, or wearable gadgets enhance or diminish the human mind? and: How does our (...) deep reliance upon ambient artificial intelligence change the shape of the human mind? Readers will discover the best philosophical analysis of what current and near future 21st technology means for the metaphysics of mind. Important questions are addressed on matters relating to the extended mind and the distributed self. Expert authors explore the role that the ubiquitous smart phone might have in creating new forms of self-knowledge. They consider machine consciousness, brain enhancement and smart ambient technology, and what they can tell us about phenomenal consciousness. While ideas of artificial general intelligence, cognitive enhancements and the smart environment are widely commented on, serious analysis of their philosophical implications is only getting started. These contributions from top scholars are therefore very timely, and are of particular relevance to students and scholars of the philosophy of mind, philosophy of technology, computer science and psychology.
