Our work aimed to study the relationships between different dimensions of school climate, moral disengagement, empathy, and bullying behaviors (perpetration and victimization). The study sample consisted of 629 students (304 boys and 325 girls) aged 12–14 years (M= 12.55,SD= 0.67). Results showed how different dimensions of school climate predicted moral disengagement, empathy, and victimization, and these, in turn, predicted bullying perpetration. The results show the need to generate favorable educational environments to reduce the levels of moral disengagement and victimization and (...) to increase empathy in students as a strategy to prevent negative consequences related to bullying.

The goal of synthetic biology is to create artificial organisms. To achieve this it is essential to understand what life is. Metabolism-replacement systems, or (M, R)-systems, constitute a theory of life developed by Robert Rosen, characterized in the statement that organisms are closed to efficient causation, which means that they must themselves produce all the catalysts they need. This theory overlaps in part with other current theories, including autopoiesis, the chemoton, and autocatalytic sets, all of them invoking some idea of (...) closure. A simple model of an (M, R)-system has been implemented in the computer, and behaves in ways that may shed light on the requirements for a prebiotic self-organizing system. In addition to a trivial steady state in which nothing happens, it can establish a non-trivial steady state in which all intermediates have finite concentrations, with their rates of degradation balanced by their rates of synthesis. The system can be regenerated from the set of food components plus a single intermediate, and maintain itself in that state indefinitely, despite continuous degradation. At the very low compartment volumes that may have existed in prebiotic conditions, for example in cavities in minerals, or in micelles formed by simple amphiphiles, statistical fluctuations in the numbers of molecules need to be taken into account. With the stochastic approach there is no non-trivial steady state in strict mathematical terms, because the system will always collapse to the trivial state after sufficient time. However, the average time before collapse is so long for volumes greater than $10^{-19}\;{\textsc{l}}$ (much smaller than the volume of the order of $10^{-15}\;{\textsc{l}}$ for a typical bacterial cell) that for practical purposes the self-maintaining state of non-null concentrations becomes significant, recalling the situation of bistability that is observed in deterministic analysis. In turn, there exists a minimum size below which the self-organizing system cannot maintain itself on chemically relevant time scales. The value of the critical volume depends on the particular concentrations and rate constants assumed, but the principle could apply generally. (shrink)

The main objective of performance sport is to obtain achievements at the highest level through the adequate development of the athlete. The scientific literature demonstrates the fundamental role played by the inclusion of certain psychological variables in the training plan. This study examined the psychological profile of kayak polo players through the variables of burnout, optimism, and mood in the hours prior to the competition, relating these to each other and to some sociodemographic data. A sample of 86 canoeists, 60 (...) men and 26 women, with an age measurement of 24.4 ± 9.1 years belonging to the first male and female kayak polo division, completed the POMS-29, the LOT-R, and the IBD-R. Athletes' levels of optimism were found to be significantly correlated with mood. Optimism also influenced emotional exhaustion. In addition, seniority and internationality were decisive factors in the level of optimism and mood achieved. (shrink)

How does thinking affect doing? There is a widely held view that thinking about what you are doing, as you are doing it, hinders performance. Once you have acquired the ability to putt a golf ball, play an arpeggio on the piano, or parallel-park, reflecting on your actions leads to inaccuracies, blunders, and sometimes even utter paralysis--that's what is widely believed. But is it true? After exploring some of the contemporary and historical manifestations of the idea, Barbara Gail Montero (...) develops a theory of expertise which emphasizes the role of the conscious mind in expert action. She aims to dispel various myths about experts who proceed without any understanding of what guides their action, and she analyzes research in both philosophy and psychology that is taken to show that conscious control and explicit monitoring of one's movements impedes well practiced skills. Montero explores a wide range of real-life examples of optimal performance, in sports, the performing arts, healthcare, the military, and other fields, and draws from psychology, neuroscience, and literature to offer a refreshing and persuasive view of expertise, according to which expert action generally is and ought to be thoughtful, effortful, and reflective.

Is the neurophysiology of pain all there is to pain? How do words and mental pictures come to represent things in the world? Do computers think, and if so, are their thought processes significantly similar to our thought processes? Or is there something distinctive about human thought thatprecludes replication in a computer? These are some of the puzzles that motivate the philosophical discipline called "philosophy of mind," a central area of philosophy.This Very Short Introduction introduces the philosophy of mind, and (...) looks at some of the most interesting and important topics in this fascinating field, including the mind-body problem and dualism. Barbara Montero also discusses minds other than our own, and the problems associated with definingconsciousness in animals, aliens and machines. Considering these and other such thorny issues such as physicalism and intentionality, she demonstrates how questions of the philosophy of mind also infiltrate disciplines outside of philosophy, including psychology, neuroscience, economics,evolutionary biology, and linguistics. As she observes, most everyone, at some time or another, has ruminated over the relation between mind and matter.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, andenthusiasm to make interesting and challenging topics highly readable. (shrink)

IntroductionStress is associated with disease and reduced leukocyte telomere length. The objective of this research is to determine if self-perceived stress is associated with telomere length in Costa Rican adults and the gender differences in this association. Findings may help explain how some populations in apparent socioeconomic disadvantage and with limited access to specialized medical services have a remarkably high life expectancy.MethodologyData come from the pre-retirement cohort of the Costa Rican Longevity and Healthy Aging Study, a population based survey conducted (...) in the households to 2,327 adults aged 53 to 66 years. The DNA to measure LTL was extracted from blood cells in laboratories of the University of Costa Rica whereas the Blackburn laboratory at the University of California performed the telomere length measurement applying the quantitative polymerase chain reaction. The relationship between telomere length and perceived stress was measured using least-squares multiple regression. Perceived stress was measured by a set of questions about family, job, finances and, health reasons to be stressed. Models included the control variables: age and sex of the participant, whether he or she resides in the Nicoya area, a “blue zone” known for its high longevity, and the aforementioned sociodemographic, health and lifestyles characteristics.ResultsStress perception and LTL are significantly different by sex. Women perceived higher stress levels than men in almost all aspects studied, except work. Women have significantly longer telomeres. Shorter telomeres are significantly associated with caregiving stress in men and with parental health concerns in women. Counter-intuitive telomere lengthenings were observed among women who feel stressed about caring for family members; and among men who feel stressed due to their family relationships as well as concerns about their own health.DiscussionResults confirm that people with self-perceived stress due to caregiving or health issues have shorter telomeres. The relationship between stress and telomere length differs between men and women. Gender relations exert a strong modifier effect on the relationship between stress and LTL: gender is related to perceived stress, telomere length, and apparently also to the way stress and LTL are related.

En opinión de Francisco Puy, el jurista debe ser una persona que agarre decidido una experiencia jurídica siempre conflictiva, la describa, la valores y ofrezca una solución para limpiarla, pacificando los problemas que presenta de apropiación, transmisión, reparto, violación y reposición de derechos. Una experiencia jurídica se inicia cuando un individuo le dice a otro que una cosa es suya y el otro o los otros asienten o consienten en que es suya. Una experiencia jurídica crece, tornándose problemática, cuando (...) un individuo o dos o todo el grupo rechazan la declaración de uno o varios que dijeron que algo es suyo, que tiene un derecho de uso, de disfrute o de propiedad; un interés legítimo o cualquier otra opción jurídica. El Derecho es la misma cosa justa, lo justo materializado en el caso concreto real y práctico; y no lo justo legal ni lo justo diseñado en grandes teorías. Este enfoque teñido de realismo abre un amplio horizonte filosófico-jurídico que Puy ha recorrido en muchas direcciones, ensayando nuevas soluciones para cuestiones viejas. Catedrático ce Filosofía del Derecho de la Universidad de Santiago de Compostela durante 45 años, Francisco Puy ha dedicado una buena parte de su pensamiento a desarrollar una forma de estudio y comprensión de la experiencia jurídica, la prudencial, diferente de la usualmente utilizada en las universidades públicas. Su camino lo ha conducido por las sendas de la Tópica, la Retórica y la Dialéctica clásicas, que ha actualizado en diálogo con la moderna teoría de la argumentación jurídica. En este libro, los colegas, amigos y discípulos del maestro dialogan con él y entre ellos, transitando un panorama temático tan complejo como sugestivo. (shrink)

Este artículo aborda el papel que juega la “admiración” en la traducción heideggeriana de tres pasajes de la Metafísica de Aristóteles. Con base en el volumen 62 de la Gesamtausgabe, se muestra que la “admiración” se relaciona con tres temas fundamentales, a saber: el mundo, la vida y la comprensión. En primer lugar, analizo el tema del mundo compartido y del mundo circundante. En segundo lugar, describo el tema de la vida, la cual es interpretada como “premura insoslayable” y “clara (...) permanencia tranquila”. En tercer lugar, desarrollo el tema de la comprensión en tres fases: “epistémica”, “propia” y “visible”. Estos temas serán retomados en trabajos ulteriores como Ser y tiempo. Por tal motivo, las lecciones de 1922 son valiosas para conocer el itinerario filosófico de Heidegger en los años veinte. Finalmente, se intenta mostrar que la triple traducción del vocablo griego θαυμάζειν realizada por Heidegger, obedece a un criterio específico de interpretación fenomenológica acorde a los temas mencionados.

Este artículo tiene como objetivo ofrecer una revisión y reinterpretación al problema teórico en la teoría de Darwin en el que se pone en relación el principio de divergencia y la competencia entre los seres vivos. Respecto a este asunto ha habido dos interpretaciones fundamentales. La primera de ellas es la de aquellos que defienden que la divergencia se ve favorecida porque implica una reducción de la competencia a la que se enfrentan los seres vivos que se desplazan de nicho (...) ecológico. Por otro lado, algunos abogan — aunque es una posición menos extendida— por una interpretación en la que la reducción de la competencia no es la ventaja, sino que lo es la especialización y, por tanto, el incremento en la competitividad, es decir, el tener mejores herramientas o capacidades para competir. En este artículo se defiende esta última tesis, fundamentalmente sostenida por William Tammone, pero desde otra perspectiva y sustentada en otros argumentos que se nutren de la propuesta de Trevor Pearce acerca de la noción de economía natural de Darwin.

El tema vertebrador como se indica en el título es el sentido de la vida. Se ofrece una serie de reflexiones sobre la relación de la persona con la matematización de la cultura. El conocimiento científico del mundo no es banal, sino que a partir de él la persona en su «voluntad de sentido» mira a esa realidad con la que interactúa. Adentrarnos en el significado de algunos fenómenos matemáticostecnológicos relacionados con la inteligencia artificial, captar los mensajes sociales que se (...) producen y penetrar en su sentido profundo puede ofrecernos claves para la comprensión (y auto-comprensión) de la persona en su estar en la sociedad actual.

Dreyfus and Dreyfus’ influential phenomenological analysis of skill acquisition proposes that expert performance is guided by non-cognitive responses which are fast, effortless and apparently intuitive in nature. Although this model has been criticised for over-emphasising the role that intuition plays in facilitating skilled performance, it does recognise that on occasions a form of ‘detached deliberative rationality’ may be used by experts to improve their performance. However, Dreyfus and Dreyfus see no role for calculative problem solving or deliberation when performance is (...) going well. In the current paper, we draw on empirical evidence, insights from athletes, and phenomenological description to argue that ‘continuous improvement’ among experts is mediated by cognitive control in three distinct sporting situations. We conclude by arguing that Sutton et al. Journal of the British Society for Phenomenology, 42, 78–103 ‘applying intelligence to the reflexes’ approach may help to elucidate the process by which expert performers achieve continuous improvement through analytical/mindful behaviour during training and competition.

There has been little research on the vocabulary of the Greek novelists. Gasda studied that of Chariton in the last century. He compared some of his terms with those of other authors and he concluded he should be placed in the sixth century A.D. Then Schmid considered that Chariton's language was not Atticist, and dated his novel in the second century or beginning of the third. In 1973 Chariton's language was studied by Papanikolaou. His research dealt above all with several (...) syntactic aspects and the use of some vocabulary, which led him to conclude that this language was closer to the koiné than that of the other novelists. But Papanikolaou went further in his conclusions: finding no trace of Atticism in Chariton, he considered him a pre-Atticist writer and, using extra-linguistic data, such as the citing of the Seres, the Chinese , placed him in the second half of the first century B.C. This chronology has been accepted by some, but already Giangrande has observed that this lack of Atticisms could have been intentional, in which case that date would be questionable. (shrink)

Recently in the philosophical literature there has been some effort made to understand the proper application of the theory of utilitarianism to worlds in which there are infinitely many bearers of utility. Here, we point out that one of the best, most inclusive principles proposed to date contradicts fundamental utilitarian ideas, such as the idea that adding more utility makes a better world.

La tesis central de este artículo es que la concepción de la razón pública propuesta por John Rawls, incluso en su versión “inclusiva”, es demasiado restrictiva y viola el principio liberal de legitimidad y la tesis de la neutralidad del estado, que constituyen elementos centrales de la teoría política de Rawls y del liberalismo político en general. Finalmente, se propone una concepción alternativa de la razón pública liberal, centrada únicamente en un deber básico de civilidad, el deber de reciprocidad, a (...) la que denominaré la concepción “abierta” de la razón pública.
