En el presente artículo se pretende demostrar que lo sonoro, lo luminoso y lo líquido, como elementos semánticos, son fundamentales para la construcción de lo fantástico y lo sepulcral en la leyenda El miserere de Gustavo Adolfo Bécquer. Estos elementos se interrelacionan por medio del ambiente sepulcral que se presenta en el texto, por medio de metáforas que los vinculan, y por medio de la forma en que se manifiestan en lo posible y lo imposible, cuya unión permite que lo (...) fantástico sea posible.

En los tiempos actuales, una materia que viene estudiando la relación entre derecho y bioética es la que se conoce como bioderecho o biojurídica, la cual trata de ofrecer una respuesta a los problemas más polémicos de la ética de la vida. Para suministrar elementos al contenido de tal disciplina se exponen en este trabajo algunos argumentos del derecho natural clásico aristotélico-tomista, mostrando cómo la corriente positivista del derecho adolece de razonamientos fuertes y, sobre todo, reivindicando la idea de dignidad (...) de la persona humana basada en su naturaleza humana. Este dato ontológico es la clave para entender el bioderecho o biojurídica y, en general, los problemas de la bioética. (shrink)

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

El objetivo de este trabajo es poner al descubierto los principales valores cognitivos y epistemológicos desde los que Warren Weaver puso en marcha el Programa de Biología Experimental, un programa que llevado a cabo desde la presidencia de la división de ciencias naturales de la Fundación Rockefeller, marcó y condicionó en buena medida el posterior desarrollo de la investigación biológica. Para tal fin se mostrará, en primer lugar, cómo fue la llegada de Weaver a la Fundación Rockefeller, así como las (...) razones bajo las cuáles el consejo de esa institución decidió entre 1932 y 1933 dar prioridad a las investigaciones biomédicas, y la manera por la cual lo hicieron. En un segundo momento, el más extenso e importante, veremos algunos de los elementos más significativos de la perspectiva epistemológica y cognoscitiva de de Weaver. Finalizaremos viendo cómo esa perspectiva, desarrollada en conexión con el Programa de Biología Experimental, inter-actuó con la visión reduccionista de la biología a la que el programa parecía apuntar. The aim of this article is to uncover the main cognitive and epistemological values that influenced Warren Weaver in starting the Experimental Biology Program, a program carried out from the time that he became president of the Natural Sciences Division of the Rockefeller Foundation, and which significantly marked and conditioned the subsequent development of biological research. To this end, we first describe the arrival of Warren Weaver at the Rockefeller Foundation, and the reasons for which the Board of this Foundation, between 1932 and 1933, decided to prioritize biomedical research, and the manner in which they did so. Then, secondly, in the largest and most important part of the article, we will present some of the most significant elements of Weaver's epistemological and cognitive perspective. Finally, we will show how this perspective, developed in connection with the Experimental Biology Program, interacted with the reductionist view of biology to which the program seemed to point.

En el océano de literatura jurídica que aparece casi todos los días en los estantes de las diferentes librerías nacionales, suelen ser pocas las ocasiones en las que se pueden llegar a encontrar trabajos sobre un tema tan importante como es el de la dignidad de la persona; la mayor parte de los libros que aparecen se refieren a cuestiones de derecho positivo, p. ej. el derecho penal, civil, administrativo, no se diga el constitucional, etcétera, y aunque cada una de (...) éstas debería tener como presupuesto básico al ser humano y la dignidad de éste, poca, muy poca atención es la que se le presta a tan trascendental asunto. Por eso deben recibirse con gusto trabajos que analicen el tema de la dignidad humana, y en un sentido más general, aquellos asuntos relacionados con las cuestiones morales en el derecho. Es el caso del libro De la dignidad humana y otras cuestiones jurídico-morales, del profesor José Luis Pérez Triviño, publicado por la prestigiosa editorial Fontamara. Trabajo interesante en el que he podido hallar muchos puntos de coincidencia y también algunos puntos de discrepancia. (shrink)

The variety of devices and the socialization of consumption have decentralized access to online information which is not retrieved directly from media websites but through social networks. These same factors have driven user interest towards a wider range of both ‘hard’ and ‘soft’ topics. The aim of this article is to identify the consumption of news on these topics among digital users in Spain. The methodology used is based on an analysis of the survey conducted as part of the Digital (...) News Report 2017. Following this analysis, a conclusion has been reached that the most popular hard news stories in Spain are those related to the local and regional community itself, and to health and education, while the most popular soft news stories relate to lifestyles and arts and culture. The analysis has revealed that increased interest in news and greater topic specialization result in more diversified use of sources, formats, and complementary routes. (shrink)

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of each referee (...) during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

There is a growing interest in improving the teaching–learning process at all levels of education, including higher education. In recent years, university institutions have been taking action to renew and modernize the way in which they teach and learn, making the process more dynamic and closer to the current social reality. Competencies such as the ability to work in a team have become essential for the successful implementation of innovative methodologies in which student participation is particularly relevant. Student acceptance is (...) key to the success of any teaching methodology; however, the influence of group work skills on satisfaction with innovative methodologies such as project-based learning has not yet been tested among university students. Thus, the objective of this study is to explore the association between group work competencies and satisfaction with PBL. A total sample of 359 students from two Spanish universities participated in the research. Our results reveal that there is a significant and positive relationship between competencies related to group work and satisfaction with PBL. In addition, a multiple regression analysis shows that the competencies “Conception of group work,” “Usefulness of group work,” “Planning of group work by teachers,” and “Group norms” increase satisfaction with the use of the PBL methodology. This work expands our knowledge about the role in increasing students’ satisfaction that is played by the ability of college students to work as a team. These findings could also guide teachers interested in new teaching methodologies. (shrink)

What role could have intrinsic motivation toward reading in an extraordinary situation like the recent confinement? This research examines the relationship between intrinsic reading motivation and reading habits in an adult population considering types of reading, gender, and distress generated by the coronavirus disease 2019 pandemic. Participants were 3,849 adults from Spain who were surveyed about their reading practices: before, during the first weeks, and after several weeks of confinement. Linear mixed effects models were used to analyze data. Results showed (...) a three-way interaction between reading frequency, IRM, and type of reading. Also, distress seems to pose a differential impact depending on the type of reading. The higher the IRM, the lesser the time devoted to study/work reading and the more to social and news reading. In this sense, IRM can function as a protective factor of reading behavior but only for leisure reading. Results support previous findings of the importance of consciously promoting this type of motivation in all individuals beyond educational contexts, since it seems to be positively related to well-being. Other results and implications are discussed. (shrink)

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

El trabajo consiste en una elucidación de los elementos que conforman el concepto de pena natural (poena naturalis) en el Derecho penal. Se puede caracterizar la pena natural como el daño o sufrimiento que recae sobre el autor de un delito, producto de la comisión del mismo, que debe ser descontado de la pena legal que ha de aplicársele. Si bien existe un mínimo acuerdo sobre esto, tanto en la jurisprudencia como en la doctrina penal se observan serios desacuerdos acerca (...) de los requisitos que se deben cumplir para reconocer que se está frente a una pena natural. Para elucidar los elementos, se utilizará el constructivismo conceptual de Ronald Dworkin, a fin de describir el desacuerdo y sus implicancias, reconocer los elementos principales de la pena natural y justificarlos bajo su mejor luz moral. ABSTRACT This study focuses on the clarification of the conceptual elements of poena naturalis in criminal law settings. The poena naturalis is the damage or suffering that falls on the convict for its commission. This damage must be deducted from the poena forensis to be applied. Although there is a minimum agreement about the concept of poena naturalis, in the jurisprudence and among legal scholars, there are serious disagreements about the elements of poena naturalis. To elucidate the elements, I will adopt Ronald Dworkin’s conceptual constructivism to describe the disagreement and its implications. At last, I will justify the main elements of the poena naturalis by their best moral light. (shrink)

La pena natural es una situación paradójica que se puede presentar cuando el autor de un delito, al cometerlo o a causa de éste, ha sufrido un daño igual o mayor al que padecería si el juez de la causa le aplicara la pena estatal prevista para tal conducta. Se da con frecuencia al juzgar ciertos accidentes viales, cuando el acusado ya carga el peso de ser quien, por imprudencia, mató a su pareja o familiar cercano, por ejemplo. Pero ¿en (...) qué situaciones y cómo cabe recurrir a la pena natural? En esta investigación, Manuel Serrano explora las diversas aristas y posturas en pugna que atraviesan este tema, donde se cruzan cuestiones como la idea de la “culpa compensada”, la prohibición de aplicar castigo doble por un mismo hecho (non bis in idem) y la clemencia judicial. El autor desmonta la estructura conceptual de la pena natural, estudia jurisprudencia argentina y recorre producciones teóricas de juristas que se han preocupado por este asunto complejo, profundo y poco abordado del derecho penal.

The hologenome concept of evolution is a hypothesis about the evolution of animals and plants. It asserts that the evolution of animals and plants was partially triggered by their interactions with their symbiotic microbiomes. In that vein, the hologenome concept posits that the holobiont (animal host + symbionts of the microbiome) is a unit of selection. -/- The hologenome concept has been severely criticized on the basis that selection on holobionts would only be possible if there were a tight transgenerational (...) host-genotype-to-symbiont-genotype connection. As our current evidence suggests that this is not the case for most of the symbiont species that compose the microbiome of animals and plants, the opportunity for holobiont selection is very low in relation to the opportunity for selection on each of the species that compose the host microbiome. Therefore, holobiont selection will always be disrupted ‘from below’, by selection on each of the species that compose the microbiome. -/- This thesis constitutes a conceptual effort to defend philosophically the hologenome concept. I argue that the criticism according to which holobiont selection requires tight transgenerational host-genotype-to-symbiont-genotype connection is grounded on a metaphysical view of the world according to which the biological hierarchy needs to be nested, such that each new level of selection includes every entity from below. Applied to hologenomes, it entails that the hologenome is a collection of genomes, and selection of hologenomes is assumed to entail cospeciation of the host with the species that constitute its microbiome. -/- Against that interpretation, I propose the ‘stability of traits’ account, according to which hologenome evolution is the result of the action of natural selection in a non-nested hierarchical world. In that vein, hologenome evolution does not entail cospeciation, and thus it does not require tight transgenerational host-genotype-to-symbiont-genotype connection. By embracing a multilevel selection perspective, I argue that hologenome evolution results from the simultaneous action of natural selection on each of the lineages that compose the microbiome, and on the assemblage composed by the host genome plus the functional traits of its microbiome. Hologenome selection occurs when the evolution of the traits of the microbiome result from their effects on the fitness of the host, and it can take the form of multilevel selection 1, or multilevel selection 2. In both cases, hologenome selection entails the evolution of microbiome traits, as well as evolution of the host genome, rather than cospeciation of lineages. (shrink)

¿Qué pasaría si, en el momento fundacional de la modernidad, el personaje principal no fuera el yo cartesiano, sino ese otro personaje que Descartes llamó genio maligno? Esa es la hipótesis que plantea el presente ensayo: ¿qué ocurriría si en lugar de la agotada certeza del yo, el mundo moderno se hubiera asentado más bien sobre la confusión y sobre la trampa que se condensan en la metáfora del genio maligno? Desde esa hipótesis, la mayor parte de las configuraciones filosóficas (...) de eso que llamamos modernidad aparecen transfiguradas, se convierten en meras repeticiones de aquel fraude básico que ocultan. Pero donde tales configuraciones velan ese gesto al repetirlo, el género de terror y los discursos sobre la angustia y la locura parecen haberlo denunciado como grietas de un edificio sin fondo. Este es el viaje apasionante que se propone en este libro, un viaje en el que autores como Poe, Stevenson o Conrad se atreven a proponernos lecturas de Nietzsche, Heidegger o Deleuze y Foucault, en el que personajes como Frankenstein o el doctor Jekyll nos enseñan aspectos inéditos de la filosofía de los siglos modernos, un viaje en el que la posmodernidad se revela como el penúltimo recurso retórico de un personaje ficticio y casi olvidado.

Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...) allows divorcing true multispecies evolutionary individuals from other multispecies assemblages and provides an adequate criterion to single out genuine evolutionary multispecies assemblages. A consequence of their criterion is that holobionts, as conventionally defined by hologenome defenders, are not evolutionary individuals except in very rare cases, and for very specific host-symbiont associations. This paper is a critical response to Bourrat and Griffiths’ arguments and a defence of the arguments presented by holobiont defenders. Drawing upon the case of the hologenomic basis of the evolution of sanguivory in vampire bats, I argue that Bourrat and Griffiths overlook some aspects of the biological nature of the microbiome that justifies the thesis that holobionts are evolutionarily different to other multispecies assemblages. I argue that the hologenome theory of evolution should not define the hologenome as a collection of genomes, but as the sum of the host genome plus some traits of the microbiome which together constitute an evolutionary individual, a conception I refer to as the stability of traits conception of the hologenome. Based on that conception I argue that the evidence presented by holobiont defenders is to the point, and supports the thesis that holobionts are evolutionary individuals. In this sense, the paper offers an account of the holobiont that aims to foster a dialogue between hologenome advocates and hologenome critics. (shrink)

Aristotle's Ethics develops a complex theory of the qualities which make for a good human being and for several decades there has been intense discussion about whether Aristotle's theory of voluntariness, outlined in the Ethics, actually delineates what modern thinkers would recognize as a theory of moral responsibility. Javier Echeñique presents a novel account of Aristotle's discussion of voluntariness in the Ethics, arguing - against the interpretation by Arthur Adkins and that inspired by Peter Strawson - that he developed (...) an original and compelling theory of moral responsibility and that this theory has contributed in important ways to our understanding of coercion, ignorance and violence. His study will be valuable for a wide range of readers interested in Aristotle and in ancient ethics more broadly. (shrink)

La ciencia de la política en el siglo veinte ha llegado a una difícil situación. La vida ha sufrido convulsiones inesperadas mientras que la ciencia que debía entender lo sucedido ha quedado apresada por la perplejidad y pos sus fracasos en la predicción y explicación de los acontecimientos. En tono crítico, el autor mantiene que "una ciudadanía de hombres y mujeres vigilantes es un dogma nuevo que no debe pasar desapercibido". La emancipación colonial, el holocausto, la caída del muro de (...) Berlín y las transformaciones vertiginosas de la tecnología han arrastrado a la ciencia política y a sus investigadores a una situación comprometida. En este libro, el autor reconstruye la teoría política del siglo veinte a través de sus grandes maestros y reclama un saber que no se separe de los hombres y mujeres que dan vida a la política cotidiana y real.

While punishment is a longstanding object of philosophical scrutiny, other controversial aspects of the justice system, such as policing, have flown under the radar. In this paper, we consider possible reasons why philosophers interested in crime and punishment have neglected policing. We make the case for a broader account of the political morality of the justice system, with a particular emphasis on policing. We sketch the outlines of an egalitarian version of such a theory, highlighting parallels between policing and the (...) welfare state. Finally, we turn to recent calls for police abolition. Evaluating such radical claims requires, we argue, going beyond the traditional confines of the philosophy of punishment and considering a more holistic and interdisciplinary theory of criminal justice.

The units or levels of selection debate concerns the question of what kind of biological systems are stable enough that part of their evolution is a result of the process of natural selection acting at their level. Traditionally, the debate has concerned at least two different, though related, questions: the question of the level at which interaction with the environment occurs, and the question of the level at which reproduction occurs. In recent years, biologists and philosophers have discussed a new (...) aspect of this debate, namely the possibility that certain multi-species consortia formed by a host and its microbiome may act as a unit of selection. This thesis, however, has not been without criticism, as it is doubtful that such consortia could meet the conditions required to achieve the degree of stability that would allow them to experience natural selection. The purpose of this paper is to systematically examine such criticisms and to defend the thesis that the holobiont/hologenome can act as a genuine level of selection both in the form of an interactor and in the form of a reproducer. To do so, it will be argued that the microbiome should be characterized in functional rather than taxonomic terms. (shrink)
