El estudio de los virus ha experimentado una gran transformación en las primeras décadas del siglo XXI. El descubrimiento de los virus gigantes ha hecho que la distinción entre algunos tipos de virus y de bacterias sea cada vez más difusa, lo que obliga a replantearse el estatus epistemológico y ontológico de estas entidades biológicas. Tanto la visión clásica de los virus por parte de la Biología, como las definiciones generales que las autoridades sanitarias, y las definiciones realizadas por virólogos (...) y microbiólogos necesitan ser revisadas para dar cabida a los conocimientos actuales sobre los virus, o más concretamente, sobre los procesos virales. En este proceso de nuevos descubrimientos aparecen nuevos términos, como virión, viroide, virobiota, viroma y virocélula que deben ser tenidos en cuenta e integrados en un nuevo marco ontológico y epistemológico general. Aunque aún estamos lejos de conseguir una definición generalmente aceptada que permita diferenciar nítidamente a los virus de otras entidades biológicas similares, al final del artículo se presenta una definición tentativa, que trata de evitar las limitaciones que presentaban las definiciones anteriores.

There is an argument by M. Dummett about the relative priority of language as a social phenomenon. The first step is to explain how the speaker and the hearer have to know the same language, ceteris paribus. The second step is to show how the speaker's idiosyncratic beliefs depend on his knowledge of common language; the last step is to appeal to Quine's principle of translation between languages in order to have a language at all.

Jackson has ellaborated an argument to show that our experiences or qualitative states gather information which cannot be obtained in any other way. Functionalists reject in many ways that experience may bring new information. The point of this paper is to argue that, if func-tionalism is right, if experiences or "qualia" are not informative, then functionalism cannot report about them. The functionalist criticism of Jackson's argument makes it impossible for any functionalist theory to know experience.

La paradoja de Moore es el tipo de absurdo de, entre otras cosas, la aserción de una oración de la forma �p pero yo no creo que p�. Propongo una explicación de la paradoja en términos del uso del pronombre personal �yo�. Más aún, recurro a un modelo del uso competente al que me referiré como modelo de la autorreferencia autoconsciente. A continuación, muestro que la explicación introducida es independiente de otras explicaciones recientes basadas en la naturaleza consciente de la (...) aserción y de la creencia. Pero, además, concluyo que está justificado pensar que ni la aserción ni la creencia son de naturaleza consciente. (shrink)

Se trata de revisar el expresivismo respecto a emisiones de la forma "Creo que p". El expresivista sostiene que una emisión de "Creo que llueve" es una expresión, y no una descripción, de la creencia de que llueve. Se propone una variación del expresivismo según la cual una emisión así expresa la creencia consciente de que llueve, en el sentido de la teoría de la conciencia de Brentano: una creencia consciente de que llueve tiene el contenido de que llueve y (...) de que él mismo, el creyente, cree que llueve.

This study analyzes the development of a culture of personal transformation in contemporary societies, showing its forms and orientations, and pointing to the factors that favor its development. This new culture unifies psychology and spirituality, emphasizes the transformational power of the experience of transcendence, and flourishes in an heterogeneous and loosely organized milieu driven by trends toward individualization and hybridization. The interpretative hypothesis is that this cultural development is a response to a societal change at the level of the individual: (...) the expansion of the self. The culture of personal transformation can be explained as a response to the existential turmoil that is inherent to the expansion of the self. (shrink)

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)

Current Perspectives in Philosophy of Biology.

The World Health Organization has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants from all Spanish regions completed the survey. Binomial (...) logistic regressions adjusted for socioeconomic characteristics, body mass index, previous HRBs, and confinement context were conducted to investigate associations between the number of weeks confined and a set of six HRBs. When adjusted, we observed significantly lower odds of experiencing a higher number of HRBs than before confinement overall in a time-dependent fashion: OR 0.63; 95% CI: 0.49–0.81 for the second and OR 0.47; 95% CI: 0.36–0.61 for the third week of confinement. These results were equally consistent in all age and gender subgroup analyses. The present study indicates that changes toward a higher number of HRBs than before confinement, as well as the prevalence of each HRB except screen exposure, decreased during the first 3 weeks of COVID-19 confinement, and thus the Spanish adult population may have adapted to the new situational context by gradually improving their health behaviors.

El conocimiento histórico –entendido como un proceso metacognitivo de asimilación constructiva sobre el pasado para explicar fenómenos– comporta un análisis del impacto y la transcendencia de determinados acontecimientos y procesos históricos, en cuya comprensión y valoración influye el concepto de relevancia histórica. Desde esta perspectiva es necesario implementar propuestas de evaluación sólidas, vinculadas al desarrollo competencial. El objetivo de este estudio es diseñar una guía de caracterización de los instrumentos evaluativos –actividades y ejercicios– más utilizados por el profesorado de Historia, (...) con el fin de optimizar los procesos de evaluación de esta competencia mediante una serie de descriptores estructurales, competenciales y transferenciales. Estos indicadores de pertinencia pueden marcar el camino de aquellos docentes que deseen perfeccionar su manera de evaluar lo históricamente determinante. En conclusión, este innovador planteamiento supone un proceso de formación continua del profesorado que contribuye a la mejora de la calidad educativa. (shrink)

The hypothalamus is a specialized area in the brain that integrates the control of energy homeostasis. More than 70 years ago, it was proposed that the central nervous system sensed circulating levels of metabolites such as glucose, lipids and amino acids and modified feeding according to the levels of those molecules. This led to the formulation of the Glucostatic, Lipostatic and Aminostatic Hypotheses. It has taken almost that much time to demonstrate that circulating long‐chain fatty acids act as signals of (...) nutrient surplus in the hypothalamus. Moreover, pharmacological and/or genetic inhibition of fatty acid synthase, AMP‐activated protein kinase and carnitine palmitoyltransferase 1 results in profound decrease in feeding and body weight in rodents. The molecular mechanism behind these actions depends on changes in the cellular pool of malonyl‐CoA and fatty acyl‐CoAs. Current evidence also suggests that this pathway may play a major role in the physiological regulation of feeding, by integrating hormonal and nutrient‐derived signals in the hypothalamus. Here, we summarize what is known about hypothalamic fatty acid metabolism and feeding control and provide future directions for research. Understanding these molecular mechanisms could provide new targets for the treatment of obesity and related disorders. BioEssays 29: 248–261, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

Antecedente. Se considera «eutanasia» al acto de acabar con la vida del paciente a petición expresa de él, para terminar el sufrimiento propio de alguna enfermedad sin perspectiva de cura. Objetivo. Evaluar los conocimientos y la percepción sobre la eutanasia en estudiantes y profesionales de medicina, demostrando los conocimientos y clasificando la percepción sobre la eutanasia. Metodología. Estudio clínico-epidemiológico, observacional, cualitativo-cuantitativo, de corte transversal y con muestreo no probabilístico por conveniencia, en los estudiantes y profesionales de medicina de un hospital (...) en Venezuela. Resultados. La muestra estudiada tuvo una distribución según grado de instrucción: 64.85% de estudiantes, 19.33% de residentes y 15.82% de especialistas. Presentaron un grado de conocimiento medio, distribuido en 84.4% de especialistas, 77.3% de residentes y 80.5% de estudiantes (p 0.051). De acuerdo con los grados de conocimiento y el apoyo a la eutanasia, el 76.18% tiene un grado medio de conocimientos (p 0.0002). Conclusión. Se demostró que existe un grado medio de conocimiento, en particular en la población estudiantil. La eutanasia no fue percibida de manera negativa, demostrando una alta significancia en la atención a las implicaciones éticas que rodean este concepto. (shrink)

Resumen: El propósito de este artículo es explorar en el contexto de Shanghái la manera en que se revelan, definen y cuestionan las distancias y las cercanías entre las culturas china y española a través de los lienzos pictóricos de Juan Antonio Baños. Su nomadismo o condición de extranjero va a plantear algunas dudas sobre la identidad y el lugar que el artista ocupa en el mundo contemporáneo, además de sugerir algunos patrones según los cuales las fronteras desaparecen, mientras que (...) otras nuevas son erigidas. El mero gesto de Baños de traducir los trazos encontrados en la ciudad de Shanghái por medio de un tejido de dislocaciones y citaciones incita una sinfonía heterogénea de espacios y tiempos variados que amplifican las posibilidades de conocimiento artístico entre Oriente y Occidente. Ante el análisis de un panorama poscolonial contemporáneo que va del hiperrealismo barroco a una epistemología retro futurista de la ciudad, pasando por el arte pop kitsch, el artículo muestra como este itinerario de traducción transcultural nos desplaza hacia un periodo post-paradigmático.: The purpose of this article is to explore in the context of Shanghai in regards to the distances and closeness between Chinese and Spanish cultures are revealed, defined and questioned, through the pictorial canvases of Juan Antonio Baños. His nomadism or status as a foreigner will raise some doubts about the identity and the place that the artist occupies in the contemporary world. In addition, the contemporaneity of his work suggests some effects according to which the borders disappear, while new ones are erected. The mere gesture of Baños´ artwork in attempting to translate the traces of Shanghai by means of a world of dislocations and citations incites a heterogeneous symphony of varied spaces and times that amplify the possibilities of artistic knowledge between East and West. Drawing from the analysis of a postcolonial framework that stretches from baroque hyperrealism to retro-futurist epistemologies of the city, right up to a kitsch pop art, the article claims that this translatable cultural itinerary displaces the ways of understanding contemporary art in China towards a post-paradigmatic period.

Current Perspectives in Philosophy of Biology.

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19.

Postmodernism may seem a particularly inappropriate term when used in conjunction with a region that is usually thought of as having only recently, and then unevenly, acceded to modernity. Yet in the last several years the concept has risen to the top of the agenda of cultural and political debate in Latin America. This collection explores the Latin American engagement with postmodernism, less to present a regional variant of the concept than to situate it in a transnational framework. Recognizing that (...) postmodernism in Latin America can only inaccurately be thought of as having traveled from an advanced capitalist "center" to arrive at a still dependent neocolonial "periphery," the contributors share the assumption that postmodernism is itself about the dynamics of interaction between local and metropolitan cultures in a global system in which the center-periphery model has begun to break down. These essays examine the ways in which postmodernism not only designates the effects of this transnationalism in Latin America, but also registers the cultural and political impact on an increasingly simultaneous global culture of a Latin America struggling with its own set of postcolonial contingencies, particularly the crisis of its political left, the dominance of neoliberal economic models, and the new challenges and possibilities opened by democratization. With new essays on the dynamics of Brazilian culture, the relationship between postmodernism and Latin American feminism, postmodernism and imperialism, and the implications of postmodernist theory for social policy, as well as the text of the Declaration from the Lacandon Jungle of the Zapatatista National Liberation Army, this expanded edition of boundary 2 will interest not only Latin Americanists, but scholars in all disciplines concerned with theories of the postmodern.

In Lukács: Praxis and the Absolute, Daniel Andrés López reassembles Lukács’s philosophy of praxis on a Hegelian basis, as a conceptual-historical totality, both defending him and proposing an unprecedented, immanent critique that raises problems for Marxian philosophy as a whole.

The first part of this paper proposes a precise definition of what a worldview is, and why there is a necessity to have one. The second part suggests how to construct integrated scientific worldviews. For this attempt, three general scientific approaches are proposed: the general systems theory as the endeavor for a universal language for science, a general problem-solving approach and the idea of evolution, broadly construed. We close with some remarks about limitations of scientific worldviews.

El presente trabajo intenta dilucidar los caracteres centrales de la incorporación del legado de Marx en la obra de León Rozitchner. La hipótesis que articula el escrito define al marxismo como una matriz de inteligibilidad que permite una continuidad y una persistencia en los tópicos centrales de la filosofía del autor argentino. En particular, me centraré en los períodos de juventud y madurez de León Rozitchner, para verificar la forma en que las múltiples transformaciones de su filosofía con el paso (...) del tiempo, mantienen una cohesión posibilitada por su marxismo, entendido como un marco teórico jamás abandonado. Se pondrá de relieve la manera en que algunas apropiaciones juveniles del legado marxista (como, por ejemplo, la noción de “ser social”) son resignificadas a partir de las transformaciones y las distancias que adquiere Rozitchner en su propia lectura de Marx, para finalizar en la elaboración novedosa de un “materialismo ensoñado”.

In most domains of human life, we are willing to accept that there are experts with greater knowledge and competencies that distinguish them from non-experts or laypeople. Despite this fact, the very recognition of expertise curiously becomes more controversial in the case of “moral experts”. Do moral experts exist? And, if they indeed do, are there ethical reasons for us to follow their advice? Likewise, can emerging technological developments broaden our very concept of moral expertise? In this article, we begin (...) by arguing that the objections that have tried to deny the existence (and convenience) of moral expertise are unsatisfactory. After that, we show that people have ethical reasons to ask for a piece of moral advice in daily life situations. Then, we argue that some Artificial Intelligence (AI) systems can play an increasing role in human morality by becoming moral experts. Some AI-based moral assistants can qualify as artificial moral experts and we would have good ethical reasons to use them. (shrink)

Shows the relevance of Schiller’s thought for contemporary philosophy, particularly aesthetics, ethics, and politics. This book seeks to draw attention to Friedrich Schiller (1759–1805) as a philosophical thinker in his own right. For too long, his philosophical contribution has been neglected in favor of his much-deserved reputation as a political playwright. The essays in this collection make two arguments. First, Schiller presents a robust philosophical program that can be favorably compared to those of his age, including Rousseau, Kant, Schelling, and (...) Hegel, and he proves to be their equal in his thinking on morality, aesthetics, and politics. Second, Schiller can also guide us in our more contemporary philosophical concerns and approaches, such as phenomenology, hermeneutics, aesthetics, and politics. Here, Schiller instructs us in our engagement with figures such as Walter Benjamin, Michel Foucault, Jacques Rancière, Roberto Esposito, and others.
