Objective: The aim of this research was to study the mediation of body dissatisfaction, physical self-concept, and body mass index (BMI) on the relationship between physical activity and self-concept in adolescents. Materials and Methods: A sample of 652 Spanish students between 12 and 17 years participated in a cross-sectional study. Physical self-concept and general self-concept were assessed with the Physical Self-Concept Questionnaire (CAF), body dissatisfaction with the Body Shape Questionnaire (BSQ), and physical activity was estimated with the International Physical Activity (...) Questionnaire (IPAQ-SF). BMI was utilized as a measurement of body composition. Structural equation modeling was used to assess the results. Results: The resulting models showed good fit indexes. Physical activity had a positive and indirect effect on self-concept (β = 0.29, p < 0.01) and direct effects on dissatisfaction (β = -0.26, p < 0.01) and physical self-concept (β = 0.20, p < 0.01). BMI had a direct effect on dissatisfaction (β = 0.31, p < 0.01) and on physical self-concept (β = -0.10, p < 0.01) and an indirect effect on general self-concept (β = -0.24, p < 0.01). However, it was only associated with physical activity in males, playing a mediating role between physical activity and body dissatisfaction. Conclusion: Physical activity can help individuals to achieve a positive self-concept and promote psychological well-being in adolescents through the improvement of physical perceptions and body satisfaction. The importance of BMI, body dissatisfaction, and physical self-concept on the configuration of the self-concept are also emphasized. Educational policymakers and Physical Education teachers should implement strategies to promote physical activity in the schools and provide a Quality Physical Education programs to increase physical activity during adolescence.

El objeto de este libro es mostrar quién fue, qué pensó y cual es el sentido, para nosotros, del pensamiento de Abu al-Ualíd Muhammad ibn Ahmad ibn Muhammad ibn Ahmad ibn Ahmad Ibn Ruxd, en adelante Averroes, nombre que deriva de la latinización del apelativo Ibn Ruxd, nacido en Córdoba en 1126 y muerto en Marrakex en 1181. Su impronta en la cultura de su tiempo le hizo figurar nada menos que entre el auténtico canon onomástico de la teología y (...) la filosofía medievales que supuso La Divina Comedia de Dante, o en el parnaso de la filosofía de Rafael en "La escuela de Atenas". Y eso no resulta incompatible con su peso central en el pensamiento racionalista que marcó el rumbo de la modernidad de donde surge nuestro mundo presente. Averroes supone una cima del pensamiento universal en cualquier tiempo y lugar. Entre los límites cronológicos que encierran una vida como la de Averroes no podemos lograr totalidades, más allá de un conjunto de fragmentos, indicios, referencias indirectas procedentes de datos que nos ofrecen autores contemporáneos o sucesores. El conjunto de todas esas informaciones, que forman la biografía del filósofo, resulta ser muy escaso y poco ilustrativo si lo comparamos con la trayectoria de su pensamiento, un proceso intelectual cuyo prodigioso esfuerzo racional deja en la sombra al Averroes persona en beneficio del Averroes pensador. Frente a los momentos destacados de una vida, cuyos límites espaciales o geográficos vienen determinados por continuos desplazamientos de ida y vuelta entre Córdoba, Sevilla y Marrakex, lugares donde desempeñó cargos oficiales, sobresale un constante y sostenido esfuerzo intelectual plasmado en sus 92 obras escritas en 72 años de vida del filósofo.

Since Darwin, Biology has been framed on the idea of evolution by natural selection, which has profoundly influenced the scientific and philosophical comprehension of biological phenomena and of our place in Nature. This book argues that contemporary biology should progress towards and revolve around an even more fundamental idea, that of autonomy. Biological autonomy describes living organisms as organised systems, which are able to self-produce and self-maintain as integrated entities, to establish their own goals and norms, and to promote the (...) conditions of their existence through their interactions with the environment. Topics covered in this book include organisation and biological emergence, organisms, agency, levels of autonomy, cognition, and a look at the historical dimension of autonomy. The current development of scientific investigations on autonomous organisation calls for a theoretical and philosophical analysis. This can contribute to the elaboration of an original understanding of life - including human life - on Earth, opening new perspectives and enabling fecund interactions with other existing theories and approaches. This book takes up the challenge. (shrink)

The first form of the inside-outside dichotomy appears as a self-encapsulated system with an active border. These systems are based on two complementary but asymmetric processes: constructive and interactive. The former physically constitute the system as a recursive network of component production, defining an inside. The maintenance of the constructive processes implies that the internal organization also constrains certain flows of matter and energy across the border of the system, generating interactive processes. These interactive processes ensure the maintenance of the (...) constructive processes thus specifying a meaningful outside. Upon this basic form of identity formation, the evolutionary and historical domain is open for the emergence of a whole hierarchy and ecology of insides and outsides. These which mutually subsume and collaborate in the maintenance of the essential inside-outside dichotomy that defines the conditions of possibility of the subjects and the worlds they generate.

This article analyzes the possibility of finding an approach favorable to religious tolerance in Thomas Hobbes’s Leviathan. With this aim, I will first establish a contrast between two interpretative groups that have guided the discussion on the subject, focusing mainly on Leviathan. On the one side, there are more “traditional” commentators of Hobbes’s works, to whom the idea of religious tolerance in Hobbes’s texts makes little or no sense; on the other hand, there are academics who defend a “revisionist” reading, (...) maintaining that Hobbes was completely favorable to religious tolerance. Second, I propose a reading of the text from the Hobbesian concept of religion, reconstructing this concept with the characterizations present in Leviathan. Finally, the two lines of interpretation are contrasted with this Hobbesian concept of religion, determining in what sense it is possible to understand Hobbes’s work as favorable to religious tolerance.

Nos proponemos analizar el pensamiento de Álvaro García Linera, uno de los intelectuales más interesantes en lengua española, y que mayor difusión está teniendo en los últimos tiempos. Para ello, tomaremos como punto de referencia cuatro de las ideas centrales dentro de la filosofía del boliviano: proyecto político, estado, hegemonía y dominación (analizando las dos últimas de manera conjunta). Comenzaremos exponiendo las influencias de García Linera, así como las peculiaridades de sus planteamientos, para centrarnos posteriormente en la etapa de su (...) producción intelectual más reciente, y acabar con una conclusión que mencionará también algunas de las críticas más importantes que se han vertido hacia el antiguo vicepresidente.

Para elaborar sua filosofia civil, Thomas Hobbes preliminarmente se dedicou ao exame daquilo que constitui a república: o homem. Em sua análise da dinâmica afetivo-cognitiva humana, tecida a partir dos conceitos de sensação, imagem, linguagem e paixão, o conceito de imaginação é apresentado como um resíduo da experiência sensível no corpo. Como tal, uma imagem estará sujeita a se eclipsar sob a luz de imagens mais fortes ou mais recentes, que podem apagá-la da mente tomando o seu lugar. O ato (...) ou faculdade de imaginar, a imaginação — para Hobbes “sensação em declínio” —, é memória, que exprime no presente a sensação passada. Lançada ao futuro, a imagem mantém-se na expressão do medo ou da esperança, paixões que impelem aos homens serem credores de certo esquema de poder. A imaginação dá a forma da expectativa, que projeta passado e presente ao futuro, como uma profecia autorrealizável, garantido a estabilidade do poder e da riqueza. (shrink)

Many moral philosophers have criticized intensive animal farming because it can be harmful to the environment, it causes pain and misery to a large number of animals, and furthermore eating meat and animal-based products can be unhealthful. The issue of industrially farmed animals has become one of the most pressing ethical questions of our time. On the one hand, utilitarians have argued that we should become vegetarians or vegans because the practices of raising animals for food are immoral since they (...) minimize the overall happiness. Deontologists, on the other hand, have argued that the practices of raising animals for food are immoral because animals have certain rights and we have duties toward them. Some virtue ethicists remain unconvinced of deontic and consequentialist arguments against the exploitation of animals and suggest that a virtue-based approach is better equipped to show what is immoral about raising and using animals for food, and what is virtuous about ethical veganism.

¿Qué es una revolución? ¿Qué fuerzas la desencadenan? ¿Por qué fases atraviesa? ¿Es un acontecimiento imprevisible, que actúa al modo de una explosión volcánica, como pensaba Joseph de Maistre, o es un fenómeno enraizado en factores observables, acumulados a lo largo del tiempo, como afirmó Tocqueville? ¿Es el resultado necesario de factores estructurales, de acuerdo con procesos deterministas de carácter inevitable, como pensaba Karl Marx, o es algo contingente, provocado y dirigido por la acción consciente de grupos sociales con propósitos (...) definidos, como demostró Ted R. Gurr? Y, de ser así, ¿están enraizados tales factores y/o responden tales propósitos a aspiraciones predominantemente materiales y económicas, o son más bien de tipo espiritual, relacionados con la dignidad y el deseo de libertad de los participantes, o incluso con percepciones transcendentes, relacionadas con la seguridad ontológica y la percepción identitaria de las sociedades y los grupos participantes? ¿Qué resultados cabe esperar de las revoluciones y qué factores inciden sobre ellos?

En este artículo se pretende realizar un análisis del origen filosófico de uno de los puntos clave que cambiaron los cimientos de la metafísica moderna a partir de la aportación de la noción de filosofía de naturaleza de Schelling, que conlleva a abrir desde el idealismo alemán una concepción alternativa de las relaciones entre la finitud y el Absoluto a las llevadas a cabo por Fichte y Hegel. Su filosofía de la naturaleza inaugurará toda una corriente de pensamiento que incluirá (...) tanto gran parte de la filosofía de Spinoza como el discurrir estético del Sturm und Drang alemán. Posteriormente, y previa enorme reflexión del tótem ineludible de la filosofía crítica kantiana y ruptura con la fichteana, la importancia de su legado filosófico no hará más que crecer, ya que de la influencia sus escritos participarán, de manera más o menos explícita, pensadores como Schopenhauer, Nietzsche, Freud o Heidegger, e incluso llegará hasta el siglo XXI de la mano de gran parte de los autores de la denominada época posmoderna, como Deleuze o Zizek entre otros.

In this article, we propose some fundamental requirements for the appearance of adaptivity. We argue that a basic metabolic organization, taken in its minimal sense, may provide the conceptual framework for naturalizing the origin of teleology and normative functionality as it appears in living systems. However, adaptivity also requires the emergence of a regulatory subsystem, which implies a certain form of dynamic decoupling within a globally integrated, autonomous system. Thus, we analyze several forms of minimal adaptivity, including the special case (...) of motility. We go on to explain how an open-ended complexity growth of motility-based adaptive agency, namely, behavior, requires the appearance of the nervous system. Finally, we discuss some implications of these ideas for embodied robotics. (shrink)

The project of growing meat artificially represents for some the next best thing to humanity. If successful, it could be the solution to several problems, such as feed- ing a growing global population while reducing the environmental impact of raising animals for food and, of course, reducing the amount and degree of animal cruelty and suffering that is involved in animal farming. In this paper, I argue that the issue of the morality of such a project has been framed only (...) in terms of the best conse- quences for the environment, animals, and humans, or in terms of deontic princi- ples. I argue that to appreciate how deep and difficult this issue is, it is necessary to consider it in terms of a virtue-oriented approach. Such an approach will reveal aspects that are not apparent, not contemplated by typical approaches, but are essen- tial to our understanding of the morality of lab-grown meat. As I argue, evaluating the issue from a virtue-oriented perspective suggests that the project of in vitro meat should not be supported because it stems from unvirtuous motivations. (shrink)

Recent research in philosophy of science has shown that scientists rely on a plurality of strategies to develop successful explanations of different types of phenomena. In the case of biology, most of these strategies go far beyond the traditional and reductionistic models of scientific explanation that have proven so successful in the fundamental sciences. Concretely, in the last two decades, philosophers of science have discovered the existence of at least two different types of scientific explanation at work in the biological (...) sciences, namely: mechanistic and structural explanations. Despite the growing evidence about the radically different nature of these two types of explanation, no inquiry has been conducted to date to determine the ontological reasons that might underlie these differences, nor the way in which these types of explanations can be systematically related with each other. Here, we aim to cover this gap by connecting this plurality of research strategies with the existence of emergent levels of reality. We argue that the existence of these different—and apparently incompatible—explanatory strategies to account for biological phenomena derives from the existence of “ontological jumps” in nature, which generate different regimes of causation that in turn demand the development of different explanatory frameworks. We identify two of these strategies—mechanistic modelling and network modelling—and connect them to the existence of two ontological regimes of causation. Finally, we relate them with each other in a systematic way. In this vein, our paper provides an ontological justification for the plurality of explanatory strategies that we see in the life sciences. (shrink)

Marcus William Hunt argues that when co-parents disagree over whether to raise their child (or children) as a vegan, they should reach a compromise as a gift given by one parent to the other out of respect for his or her authority. Josh Millburn contends that Hunt’s proposal of parental compromise over veganism is unacceptable on the ground that it overlooks respect for animal rights, which bars compromising. However, he contemplates the possibility of parental compromise over ‘unusual eating,’ of animal-based (...) foods obtained without the violation of animal rights. I argue for zero parental compromise, rejecting a rights-oriented approach, and propose a policy that an ethical vegan parent and a non-vegan co-parent should follow to determine how to raise their children.

En este artículo sostenemos que el discurso del emprendimiento opera como un dispositivo de individualización de la relación salarial que oculta el fuerte contraste entre el plano ideal –autonomía, independencia subjetiva, éxito– y los obstáculos materiales reales –profundización del endeudamiento, alta proporción de fracaso, precarización–. Analizamos empíricamente dos casos: 1) el Foro de Activación para el Empleo de la Comunidad de Madrid que promueve lo que llamamos el narcisismo competitivo neoliberal; y 2) los contrastes entre el plano ideal y material (...) en los discursos de personas en paro entrevistadas durante 2012 y 2013. Concluimos que las políticas de empleo que promocionan el emprendimiento no resuelven el problema del desempleo sino que, fundamentalmente, sirven para gobernar políticamente la precariedad masiva. Proponemos utilizar las categorías de emprendeudores y de emprendeudamiento para una mejor comprensión sociológica del discurso del emprendimiento.This article argues that the entrepreneurship discourse operates as an individualization apparatus of the wage relation which hides the strong contrast between the ideal level -autonomy, subjective independence, success- and the real material obstacles –deepening of debt, high failure rate, precarization-. Two cases are empirically analyzed: 1) The Activation for Employment Forum organized by Madrid regional government, which promotes what we call competitive neoliberal narcissism; and 2) the contrasts between the ideal level and the material level in the discourses of unemployed people who were interviewed in 2012 and 2013. It is concluded that employment policies that promote entrepreneurship do not solve the problem of unemployment but mainly serve to govern politically the massive precariousness. It is proposed to use the categories of emprendeudores and emprendeudamiento [entrepreneurs + debt category] for a better sociological understanding of the entrepreneurship discourse. (shrink)
