Aunque el denominado problema de marco generó múltiples debates a finales del siglo pasado, aún es un problema fundamental para el avance en las Ciencias Cognitivas, en general, y para la Inteligencia Artificial, en particular. En este trabajo, y restringiéndonos al aspecto lógico del problema, postulamos que la discusión actual y subyacente a este aspecto gira en torno a cómo determinar lo que no cambia en términos de acciones y propiedades dentro de un sistema lógico formal. Es sobre este aspecto, (...) y en función de sus dificultades (i) definicional y (ii) resolutiva, que en este trabajo argumentaremos que el denominado “criterio temporal” no solamente puede estimarse como uno los principales requerimientos teóricos para (i) resolverlo sino también para (ii) explicitar más claramente su dificultad principal, a saber, “lo que es relevante” frente al cambio en el tiempo. De esta manera, sostenemos que el razonamiento lógico-temporal resulta necesario para construir cualquier solución íntegramente satisfactoria del aspecto lógico del problema de marco entendido como el modo en que, inmediatamente, determinamos relevancia frente al cambio.

The technical possibilities of biomedicine open up the opportunity to intervene in ageing itself with the aim of mitigating, reducing or eliminating it. However, before undertaking these changes or rejecting them outright, it is necessary to ask ourselves if what would be lost by doing so really has much value. This article will analyse the desirability of ageing from an individual point of view, without circumscribing this question to the desirability or undesirability of death. First, we will present the three (...) most widely used arguments to reject biomedical interventions against ageing. We will argue that only the last of these arguments provides a consistent answer to the question of the desirability of ageing. Second, we will show that the third argument falls prey to a conceptual confusion that we will call the paradox of ageing: although ageing entails negative health effects, it leads to a life stage with valuable goods. Both valuations, one positive and the other negative, refer to two different dimensions of ageing: the chronological and the biological. We will defend that, by not adequately distinguishing these two types of ageing, it does not become apparent that all the valuable goods exclusive to ageing derive only from its chronological dimension. Third, we will argue that, if we just conceive ageing biologically, it is undesirable. We will elaborate on the two kinds of undesirable effects biological ageing has: direct and indirect. Finally, we will respond to potential objections by adducing that these are insufficient to weaken our argument. (shrink)

We have recently stated the reasons why we claim that biological ageing is undesirable. Räsänen has responded to our article by arguing that this process has certain desirable aspects and, therefore, our position is inconsistent. Räsänen develops two arguments to defend his position. We will call the first the argument from the totality of the ageing process and the second the argument from the reduced goods of the ageing process. In this reply, we will give reasons to show that both (...) arguments fail. The first, on the one hand, starts from a dubious conception of ageing and, on the other hand, even accepting this conception, its reformulation is morally empty. The second incurs in an absurd conclusion. (shrink)

This article explores the possibilities of reinforcing ethics education at the university level within the context of new internationalisation processes. The situation in Spain is used as a case study. The article begins with a review of the rationale behind this issue and goes on to analyse the place of the ethical dimension in education in the proposals for adapting Spanish university degree programmes to the European Higher Education Area. Fieldwork carried out at three higher education institutions reveals that, while (...) professors accept the institutional function of the university in ethics education, their hazy conception of the matter weakens the likelihood of a pedagogical approach in‐keeping with the level of importance given to such a function.

The price of copper is unstable but it is considered an important indicator of the global economy. Changes in the price of copper point to higher global growth or an impending recession. In this work, the forecasting of the spot prices of copper from the New York Commodity Exchange is studied using a machine learning method, support vector regression coupled with different model schemas (recursive, direct and hybrid multi-step). Using these techniques, three different time series analyses are built and its (...) performance are compared. The numerical results show that the hybrid direct-recursive obtains the best results.

Resumen Este trabajo reconstruye la caracterización de “positivismo” en tres obras centrales de Horkheimer. Se afirma que, en el uso del término, Horkheimer incurre en una doble equivocidad, pues lo utiliza indistintamente para referirse al positivismo decimonónico y al del siglo XX; además, no reconoce las diferencias internas entre las posiciones de los positivistas contemporáneos. Asimismo, se muestra que muchos rasgos que se consignan como propios del positivismo del siglo XX no tienen justificación en los textos de esa tradición, de (...) manera que la categoría horkheimeriana de “positivismo” se convierte en una entidad interpretativa respecto de la cual la Escuela de Fráncfort se considera antagónica. A partir de lo anterior se realiza una crítica a las interpretaciones del autor.This paper reconstructs the characterization of “positivism” in Horkheimer’s works. We argue that in the use of this term, Horkheimer makes a misinterpretation, then he uses it in order to refer to both nineteenth century positivism and the positivism of the twentieth century; at the same time, he does not recognize the significant contrasts between the positions of the twentieth century positivists. We also show that many of the features Horkheimer sets out for twentieth century positivists find no correlation in texts belonging to this tradition, which makes Horkheimer’s concept of “positivism” an interpretative entity in opposition to Frankfurt School. From the foregoing, we carry out a critique of the interpretations made by the author. (shrink)

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

Blockchain is a pioneering technology that allows the creation of innovative information exchange ecosystems thanks to unique properties, such as immutability, distribution and transparency. By combining this technology with the emergent internet of things (IoT), many innovative business models can be created. The main objective of this work is to present the design and an initial implementation of a decentralized rental system that takes advantage of smart contracts developed on a public blockchain, combined with the potential of the IoT and (...) its intimate relationship with cyber-physical systems. The logic to be implemented in the blockchain is applied in this paper by using the Ethereum programming language, so that the developed application covers the entire car rental process offered in traditional web applications, but adding more autonomy, functionalities and ease of use for both lessees and lessors. Following Ethereum application development guidelines, all business logic is located in the smart contracts implemented in the network, where they can be used to control the car rental system. While this is a work in progress, the results obtained in the first proof of concept have been very promising. (shrink)

With the advance of biomedicine, certain individuals and groups are vulnerable because of their incapacities to defend themselves. The International Bioethics Committee as a UNESCO working group has for the last several years dedicated to deepen this principle of human vulnerability and personal integrity. This book serves to supplement this effort with a religious perspective given a great number of the world's population is affiliated with some religious traditions. While there is diversity within each of these traditions, all of them (...) carry in them the mission to protect the weak, the underprivileged, and the poor. Thus, here presented is a collection of papers written by bioethics experts from six major world religions-Buddhism, Christianity, Confucianism, Hinduism, Islam, and Judaism-who were gathered to discuss the meaning and implications of the principle of vulnerability in their respective traditions.

El artículo aborda la pandemia del covid-19 como elemento contingente y su efecto de develamiento respecto de algunas manifestaciones contemporáneas de la ideología neoliberal en Latinoamérica. De esta forma, en base a conceptos filosóficos y psicoanalíticos de orientación lacaniana planteados fundamentalmente por Slavoj Žižek, se examinan los usos críticos de la noción de ideología en sus diversas manifestaciones: miedo al otro, imposición de la lógica del empresario de sí, destrucción de lazos sociales, extractivismo de recursos naturales y fetichización de los (...) discursos de unidad frente a la pandemia. La hipótesis radica en que la pandemia presenta una oportunidad para repensar la subjetividad contemporánea, mediante la confrontación con el Real que bordea a la simbolización y, en definitiva, a la captura ideológica, a fin de poner en cuestión la afirmación de que no hay alternativa.

The aim of the paper is that of discussing some recent antipositivist theses, with specific reference to the arguments that focus on the alleged incapability of legal positivism to understand and explain the complex normative structure of constitutional states. One of the central tenets of legal positivism (in its guise of “methodological” or “conceptual” positivism) is the theory of the separation between law and morality. On the assumption that in contemporary legal systems, constitutional law represents a point of intersection between (...) law and basic moral values, antipositivists contrast legal positivism with two main arguments. First, on a more general level, the positivist theory of the separation between law and morality is questioned; then, and consequently, the “neutrality thesis” in the juristic study of law is rejected. The author discusses both these antipositivist arguments, and offers a brief defence of methodological positivism. (shrink)

El presente trabajo propone determinadas aproximaciones iusfilosóficas al discurso jurídico, a partir de los estudios realizados por Walter Benjamin sobre Franz Kafka. La investigación se realiza con las herramientas metodológicas que aportan las “teorías críticas del derecho” y los marcos teóricos que indagan la relación “derecho-literatura”. Los textos, discusiones y apuntes realizados por el pensador alemán permiten movilizar un análisis de determinados tópicos y categorías pertenecientes al espacio jurídico. Las investigaciones que realiza en torno a la figura de Kafka ofrecen (...) insumos para indagar la formación, despliegue y conservación del derecho. Desde la obra kafkiana, Benjamin visibiliza y desarticula los conceptos nodales de justicia, ley, poder y violencia, lo que permite dar cuenta de los mecanismos y dispositivos que hacen posible el sustento mitológico del derecho.

Raimo Tuomela, late Professor Emeritus at the Centre for Philosophy of Social Sciences (TINT), University of Helsinki, is widely regarded as one of the most important philosophers of our time. He published extensively on various topics within social philosophy; particularly, on social action, cooperation, group belief, group responsibility, group reasoning, social practices, and institutions. To celebrate his legacy, this volume engages with and delves deeply into his philosophy of sociality. By gathering original essays from a world-class line-up of social ontologists, (...) social action theorists, and social philosophers, this collection provides the first comprehensive and critical treatment of Tuomela's outstanding contribution to social ontology and collective intentionality.

The general concept of a trope – that of a non-shareable character-grounder – admits of a distinction between modifier tropes and module tropes. Roughly, a module trope is self-exemplifying whereas a modifier trope is not. This distinction has wide-ranging implications. Modifier tropes are uniquely eligible to be powers and fundamental determinables, whereas module tropes are uniquely eligible to play a direct role in perception and causation. Moreover, each type of trope theory faces unique challenges concerning character- grounding. Modifier trope theory (...) faces challenges concerning the inscrutability of predication and the incompatibility with bundle theory, whereas module trope theory faces challenges concerning character overdetermination and a collapse into austere nominalism. These differences indicate that the modifier/module distinction divides the advantages of general trope theory and thus presents the trope theorist with a pivotal choice. (shrink)

In this paper I explore Michael Loux’s important distinction between “tropes” and “tropers”. First, I argue that the distinction throws into relief an ambiguity and discrepancy in the literature, revealing two fundamentally different versions of trope theory. Second, I argue that the distinction brings into focus unique challenges facing each of the resulting trope theories, thus calling into question an alleged advantage of trope theory—that by uniquely occupying the middle ground between its rivals, trope theory is able to recover and (...) preserve the insights of these views. Ultimately, the distinction suggests that trope theory is a divided house. (shrink)

The article analyzes the social representations of ICTs’ appropriation for community empowerment by social movements. The study includes two recent Latin American student social movements: the Mexican #YoSoy132 and the Chilean student movement. Discourse analysis was used to examine interviews with participants in these social movements as well as other texts associated with their episodes of collective action. The discourse analysis was focused on four main dimensions of the social representations of ICTs’ appropriation: (1) the interrelationships between the technological and (...) the socio-political and cultural dimensions; (2) the tension between a visibility-centered and an articulating-focused use of ICTs; (3) the tension between the individual and the collective dimensions; and (4) the articulation between ICTs-based collective action and offline one. The findings indicate that the online/offline and the visibility/articulation tensions are relevant dimensions, in an articulated way, of the social representation of ICTs’ appropriation for collective empowerment. The results also indicate that the sociopolitical goals of the social movements are a central mediation for the process of configuration of the social representation, as it is proved by the importance of the individual/collective tension for the process.

Este análisis teórico busca analizar, por una parte, en la inmersión de la obra del pensador galés Raymond Williams y, por otro lado, el acercamiento a lo que podemos denominar como Estudios Culturales Británicos, una propuesta metodológica y política plausible en virtud de pensar nuestro presente con una mirada y una sensibilidad diferente a lo que ampliamente se ha caracterizado como «presentismo» o futuros cancelados. Para ello, retomar la obra de un pensador parcialmente olvidado en las últimas décadas, no solo (...) nos permitirá atisbar posibilidades de pensar futuros diversos, sino que nos obligará a tomar en consideración una caja de herramientas, sugerente, que terminó defendiendo con matices, contradicciones e incorporaciones hasta el final de su vida en 1988.

El objetivo de este artículo es criticar la representación tradicional del trabajo periodístico de Karl Marx, habitualmente olvidado por un canon engañoso que sólo asume sus artículos al precio de convertirlos en una obra menor. Uno de los problemas de esta concepción tradicional es que disocia sus contribuciones teóricas y económicas del desarrollo histórico del pensamiento del autor . Intentaremos señalar la importancia del periodismo maduro de Karl Marx en dos áreas: en la construcción de los conceptos centrales de su (...) crítica contra el capitalismo y en la producción de cartografías políticas para intervenir en el conflicto de clases. Este artículo plantea varias hipótesis y afirmaciones tentativas sobre el periodismo de Karl Marx que pueden servir como punto de partida de una investigación crítica. (shrink)

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most developed countries in the (...) world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.
