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)

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)

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)

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.

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.

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)

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.

Background: The high level of satisfaction of users of a health service is largely due to the fact that they receive excellent care from healthcare professionals. Compassionate care is an essential component of excellent care. But what do nurses understand compassion to be? Research objectives: To analyse the concept of compassion from the perspective of nurses in the Andalusian Public Health System, Spain. Research design: This is a qualitative study following the grounded theory model. Four focus groups and 25 in-depth (...) interviews were conducted. Participants and research context: A total of 68 nursing professionals working in the Andalusian Public Health System (Spain) participated. Theoretical sampling was used, with participants being recruited using the snowball technique. Ethical considerations: This research was approved by the Research Ethics Committee of the Centro-Almería Health District (CEICA 27/9/17). Findings: From the analysis of the data, four themes emerged that helped to understand the concept of compassion according to nurses: ‘Negative perception of the term compassion’, ‘Compassion and empathy as synonyms’, ‘Beyond empathy’, and ‘Effects of having a compassionate attitude’. Discussion: Nurses perceive the concept of compassion differently to each other and even contradictorily. This concept is imbued with cultural elements, which adds confusion to understanding it, and is even perceived as something negative similar to pity. Conclusion: Nurses confuse the concepts of empathy and compassion as if they were synonymous. Before considering training in compassion for healthcare professionals, it is essential to clarify the concept of compassion through educational interventions. (shrink)

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

I provide a variation on ideas presented by Walton and Currie, elaborating the view that fictive utterances are characterized by a specific form of illocutionary force in the family of directives – a proposal or invitation to imagine. I make some points on the relation between the proposal and the current debates on intentionalist and conventionalist views, and I discuss interesting recent objections made by Stacie Friend to the related, but crucially different, Gricean view of such force advanced by Currie (...) and others.

This article critically examines the domination exerted by big digital companies on the current social, economic, and political context of modern societies, with a particular focus on the implications for the proper functioning of democracy. The objective of this article is to introduce and develop the concept of datafeudalism, expose its emergence for the proper functioning of modern societies and democracy, and to propose courses of action to reverse this situation. To achieve this purpose, firstly, the evolution from surveillance capitalism (...) to datafeudalism will be discussed. Secondly, the structures and operating logic of data feudalism will be analyzed. Thirdly, the harmful impacts of datafeudalism on the proper functioning of the democratic systems of the European Union will be examined. Finally, an attempt will be made to outline courses of action that will make it possible to reverse the situation of economic, social and political tyranny exercised by big digital companies through datafeudalism.

María Lugones was a feminist philosopher whose work spanned four decades, two continents, and multiple languages. Over the course of her career, her writing made major contributions to feminist ethics, the philosophy of race, lesbian epistemology, and decolonial thought. She passed away on July 14, 2020, after many years of poor health, leaving behind an influential legacy and a substantial body of unpublished work.

I defend a Deferred Ostension view of quotation, on which quotation-marks are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. On this view, the quoted material works like Nunberg’s indexes in his account of deferred ostensión in general. The referent is obtained through some contextually suggested relation; in the default case the relation will be … instantiates the linguistic type __, but there are other possibilities. In this way, the (...) deferred ostension view deals with a problem I pointed out for the identity proposal in my earlier work, that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens (see the examples on p. 261 of García-Carpintero 1994).

Resumen Nombrar implica ejercer el poder sobre lo nombrado, involucra coacción y coerción social. La atribución de nombres, adjetivos, designaciones, favorece la taxonomía cognitiva, pero también socio-ideológico-cultural. Cuando una Institución al servicio del Estado nomina, esas denominaciones tienen consecuencias en los sujetos nombrados. En México, a través de las prácticas semiótico- discursivas se llevó a cabo esta edificación del concepto de discapacidad con importantes implicaciones. El objetivo de este artículo es describir la construcción discursiva, a través de la historia de (...) la nominación de la discapacidad para vincular este hecho con el imaginario social de México y revisar las implicaciones socio-ideológicas resultantes. Para efectuar un primer acercamiento, estudiamos los términos con que se designa la discapacidad en los Censos de población y vivienda realizados por el organismo responsable y sustentamos la exposición del proceso a partir de las propuestas de Lyons y Serrano sobre las implicaciones semánticas vinculadas con la designación; de Thiebaut respecto a la articulación semántica del nombre con la pragmática del texto, y con apoyo en Koike para la co-construcción del significado.

The origin of the eukaryotic cell nucleus and the selective forces that drove its evolution remain unknown and are a matter of controversy. Autogenous models state that both the nucleus and endoplasmic reticulum (ER) derived from the invagination of the plasma membrane, but most of them do not advance clear selective forces for this process. Alternative models proposing an endosymbiotic origin of the nucleus fail to provide a pathway fully compatible with our knowledge of cell biology. We propose here an (...) evolutionary scenario that reconciles both an ancestral endosymbiotic origin of the eukaryotic nucleus (endosymbiosis of a methanogenic archaeon within a fermentative myxobacterium) with an autogenous generation of the contemporary nuclear membrane and ER from the bacterial membrane. We specifically state two selective forces that operated sequentially during its evolution: (1) metabolic compartmentation to avoid deleterious co‐existence of anabolic (autotrophic synthesis by the methanogen) and catabolic (fermentation by the myxobacterium) pathways in the cell, and (2) avoidance of aberrant protein synthesis due to intron spreading in the ancient archaeal genome following mitochondrial acquisition and loss of methanogenesis.

I believe in metaphysical nihilism, the thesis that there could have been no concrete objects, because I believe in a version of the subtraction argument, the subtraction argument*, that proves it. But both Jonathan Lowe (2002) and Alexander Paseau (2002) express doubts about the subtraction argument*. Paseau thinks the argument is invalid, and Lowe argues that invoking concrete* objects is unnecessary. Furthermore Lowe attempts to rebut my objections (Rodriguez-Pereyra 2000) to his anti-nihilist argument (Lowe 1998). In this paper I defend (...) the subtraction argument* from Paseau's and Lowe's criticisms as well as show that the premises of Lowe's anti-nihilist argument are still lacking support. (shrink)

El siglo XXI ha visto aflorar ultranacionalismos propios del pasado. El neonazismo tiene su razón de ser en el ataque inequívoco contra las minorías, a partir de una ideología racista, xenófoba y excluyente, que tiene como máxima expresión la negación de muchos de los genocidios históricos. Cada vez más partidos de todo el mundo defienden algunas de estas ideas y modelos de pensamiento en sus programas, suavizándolas a la par que van ganando peso en las instituciones e instaurando su discurso (...) e idearios en la ciudadanía. El objetivo de este estudio es analizar la efectividad de una propuesta docente sobre el Holocausto en estudiantes de la etapa de Bachillerato. Para ello, se ha creado un plan de acción que fomenta la indagación y pretende desarrollar una conciencia que promueva el pensamiento ético y critico de estos hechos. Los resultados son muy positivos y confirman que el Holocausto puede y debe trabajarse con documentos históricos, fuentes de internet y otros recursos que potencian el trabajo en grupo y la motivación hacia el conocimiento y la crítica de estos hechos, preservando la memoria histórica.

The organism-in-its-environment is recognized as the basic unit of analysis when dealing with living beings. This paper seeks to define the fundamental implications of the concept of the organism-in-its-environment in terms of the biosemiotic concept of human distributed cognition. Human distributed cognition in a biosemiotic context is defined as the ability of a self-referencing organism-in-its-environment to interact with its environment to satisfy its physiological and social needs to survive and sustain itself. The ontogenetic development of the organism-in-its-environment serves as the (...) backdrop to discover the implications of distributed cognition that have general applicability in organisms, but in this paper, are made relevant to human beings.
