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)

There are 2 main problems with the current periodic table: artificial breaks from a given noble gas to the next alkali metal (along with the common protrusion of the “f” block) and hydrogen placed in the alkali group, although this gas also exhibits halogen properties. This paper proposes arranging chemical elements in a square spiral with hydrogen at the centre. This element is also above lithium but passes above fluorine to connect with helium, representing its dual alkali and halogen nature (...) effectively. Then the spiral moves outwards in a counter-clockwise direction, avoiding artificial breaks and following the natural direction of reading for the “s” and “p” blocks elements placed at the bottom of the spiral. Furthermore, this proposed square spiral improves upon previous Janet´s and Benfey´s representations with a more regular shape to draw, an effective depiction of the dual nature of hydrogen, and easily identifiable orbital blocks without the need for protrusions.

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 paper focuses on the description and analysis of three codices from Biblioteca Nacional in Madrid with the aim of redefining their origin, dating, authorship, and content. Connecting their production to the environment of the Sacromonte affair and identifying Pedro de Castro’s hand allows to expand what was known so far about his attempts to learn Arabic and delve into the most controversial aspects of the Lead Books. The grammatical and religious contents, in addition to the copious marginal notes linked (...) to the sources he used, provide valuable information on his selection of works. Grammatical materials such as al-Āŷurrūmiyya, of which different versions are preserved in these codices, were being published in Rome and Leiden and would be widely disseminated. The building up of his library, to which these codices must have belonged, runs in parallel to the construction of an orientalist knowledge in modern Europe. (shrink)

Fear to contamination is an easy-to-provoke, intense, hard-to-control, and extraordinarily persistent fear. A worsening of preexisting psychiatric disorders was observed during the COVID-19 outbreak, and several studies suggest that those with obsessive–compulsive disorder may be more affected than any other group of people. In the face of worsening OCD symptoms, there is a need for mental health professionals to provide the support needed not only to treat patients who still report symptoms, but also to improve relapse prevention. In this line, (...) it is recommended to improve alternative strategies such as online consultations and digital psychiatry. The aim of this study is to develop augmented reality stimuli that are clinically relevant for patients with cleaning OCD and assess their efficiency to obtain emotionally significant responses. Four AR stimuli were developed: a plastic bag full of garbage, a piece of bread with mold, a dirty sports shoe, and a piece of rotten meat. All stimuli were shown to a clinical group and a control group. Relevant results were the design of the AR stimuli. These stimuli were validated with the statistical difference in perceived anxiety in the meat stimuli between the clinical and control groups. Nevertheless, when looking at effect sizes, all stimuli present effect sizes from small to large, with both shoe and bread between small and medium effect sizes. These results are a valuable support for the clinical use of these AR stimuli in the treatment of cleaning OCD. (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.

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.

O presente artigo é um estudo de escolástica barroca colonial que combina elementos lógicos, raciocínios práticos e probabilismo, para compreender o movimento processual das deliberações jurídico-políticas sobre “guerra e paz” no pensamento de Juan de Solorzano Pereira. Pensador escolástico do período barroco ibero-americano que residiu por mais de duas décadas nas Índias ocidentais, que elaborou e sistematizou o Direito Indiano, De Indiarum iure. Corpo sistemático e erudito no qual se encontram compiladas cédulas reais, leis, disposições ou mandatos régios; os (...) quais eram destinados a guiar os assuntos próprios de governo nas Índias ocidentais, fundamentados na guerra justa e na paz republicana. Na Filosofia do Direito Indiano de Solórzano Pereira, a opinião provável sobre fatos e direitos não se restringe aos atos perfeitos e os absolutos que se acreditam ter em opiniões mais prováveis do passado e do presente, porque a probabilidade nessa filosofia do direito está aberta ao futuro condicional, onde novas opiniões podem produzir dúvidas nos fatos e no direito, podendo se tornar em opiniões mais coerentes, seguras e mais prováveis que as anteriores, pela aceitabilidade racional sobre o direito em questão. Erros abrem brechas e podem ser motivos suficientes para modificar direitos por usucapião, retenção, prescrição, restituição. (shrink)

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)

El presente trabajo investiga las tesis sobre el poder civil de Alonso de la Veracruz que buscan incorporar en la comunidad política española a los habitantes autóctonos del Nuevo Mundo, tesis que suelen relacionarse con F. de Vitoria y el tomismo español, y que últimamente son consideradas parte del republicanismo novohispano elaborado desde la periferia americana. Se busca demostrar que su propósito era aplicar una teoría de derechos naturales, sin que ello implique participación política de los indios americanos. Se analiza (...) la postura del fraile frente a la diversidad cultural y la guerra contra los indios. The paper explores Alonso de la Veracruz's theses on civil power, which sought to integrate the native inhabitants of the New World into the Spanish political community. These theses, which have usually been associated with F. de Vitoria and Spanish Thomism, have recently come to be considered part of a Novohispanic republicanism developed in the American periphery. The article seeks to show that the purpose of such theses was to apply a theory of natural rights that did not entail the political participation of the indigenous population, as well as to analyze Veracruz's position regarding cultural diversity and the war against the indigenous peoples.

¿Toda regla social es una convención aceptada por un acuerdo de voluntades? A esta pregunta, Ramón Ortega responde negativamente en su libro Compromiso mutuo y derecho: un enfoque convencionalista. Según el autor, el carácter normativo del derecho no estaría justificado por la "vaga, oscura y controvertida noción de aceptación" de Hart, sino por otra, más general: el compromiso mutuo, tomada de la metafísica social de Margaret Gilbert. Pero ¿cuál es la diferencia entre el hecho de que dos o más personas (...) acepten una convención y que exista entre ellas un compromiso mutuo? Pensemos en un famoso y sutil ejemplo tomado de la propia Gilbert: Ana y Miguel caminan uno cerca del otro al salir de un curso. (shrink)

Durante el decenio que Hans Kelsen ejerció como docente de Derecho Internacional en Colonia y Ginebra, entre 1930 y 1940, desarrolló un cuerpo teórico del Derecho Internacional con una marcada vocación pacifista. Ante los graves sucesos bélicos de la II Guerra Mundial, Kelsen clamó, desde su obra la necesidad de una profunda reforma de las instituciones internacionales para conseguir la paz mundial. En este artículo se trata de exponer algunos de los rasgos fundamentales de esa teoría del Derecho Internacional (...) que se encuentran en la base de una contundente propuesta pacifista, prestando especial atención a los conceptos de guerra, coacción y autotutela.

Los textos permiten trazar una imagen de la mujer y de los usos lingüísticos que caracterizan al español (...) cubano del siglo XIX. (shrink)

Francisco de Vitoria en sus comentarios a la Summa Theologiae y en la Relectio de bello admite que un simple ciudadano tiene la posibilidad (incluso la obligación) de no combatir en una guerra que él, en conciencia, considera injusta. Aunque no tiene obligación de examinar por sí mismo las causas de la guerra, no puede dejar de obrar en conciencia. Lo contrario a como actúan, por ejemplo, los mercenarios, siempre dispuestos a combatir en cualquier guerra, sea justa (...) o no. Sería un precedente de la objeción de conciencia; pero no a combatir en cualquier guerra, sino en “esta guerra” en particular. No obstante, en caso de duda, un simple ciudadano podría combatir obedeciendo a su príncipe, fiado de la rectitud de intención del gobernante. (shrink)

Pese a que se trata de una de las obras de Machiavelli menos conocidas y estudiadas en la actualidad, el tratado Dell’arte della guerra (1521) encontró una rápida difusión en la Europa de su siglo. Publicada en París en 1546 (en traducción de Jean Charrier), la obra fue analizada críticamente algunas décadas más tarde en la versión definitiva del Discours d’Estat contre Machiavel (Ginebra, 1585) del jurista calvinista Innocent Gentillet. Sintetizando los argumentos que Gentillet ofreció en este tratado frente (...) al ejército de milicias ciudadanas propuesto por Machiavelli, mostramos su interrelación con las críticas dirigidas por el hugonote al resto de escritos maquiavelianos (en particular Il Principe y los Discorsi). Se trata, de acuerdo a nuestra interpretación, de la primera crítica sistemática al pensamiento político y social de Machiavelli. Al mismo tiempo, supone la respuesta virulenta de la Francia nobiliaria al republicanismo neo-romano defendido por el florentino. (shrink)

El presente artículo expone la crítica a Kant realizada por los autores de la nueva cosmopolítica, corriente contestataria que renuncia al ideal de paz del cosmopolitismo, denunciando lo que Isabelle Stengers llama la tentación de Kant: la imposición de una paz trascendente que, impuesta de manera global como ajuste a un tribunal externo, encerraría una declaración de guerra. El artículo examina esta acusación y responde explicando el sentido del ideal cosmopolita en Kant y su relación con el logro de (...) la paz y el progreso moral de la humanidad, señalando tres aspectos fundamentales: la relación del ideal kantiano con la plasticidad humana, el papel del conflicto en la antropología de Kant y la consideración kantiana de la humanidad como un todo moral. Se concluye indicando que, a la luz de estas matizaciones, esta impugnación de Kant habría de ser revisada. (shrink)
