Emergent phenomena are quite interesting and amazing, but they present two main scientific obstacles: to be rationally understood and to be mathematically modelled. In this paper we propose a powerful mathematical tool for modelling emergent phenomena by applying category theory. Furthermore, since great part of biological phenomena are emergent, we present an essay of how to access an emergence from observational data. In the mathematical perspective, we utilize constructs (categories whose objects are structured sets), their operations and their corresponding generalized (...) underlying functor (which are not necessarily faithful) to define emergence. From this definition, we elaborate several results concerning homomorphism between emergences, representability, pull-back, push-out, equalizer, product and co-product of emergences among other results. After we have presented such mathematical model, we utilize a hierarchical structure as example—from molecules to a flatworm—, in order to understand the relation between biological systems and its underlying emergence in a hierarchical model.

Las formas de pensar la dominación social han cambiado durante las últimas décadas en la teoría política, dejando atrás esquemas diádicos con centros de poder definidos. En este artículo comparamos autores de la nueva lectura de Marx, la crítica del valor y la interseccionalidad, que han ayudado redefinir la dominación social durante las últimas décadas complejizando los paradigmas que las preceden, el marxismo tradicional y el feminismo negro, respectivamente. El artículo analiza el concepto de dominación social de estas nuevas lecturas (...) de Marx atendiendo a las críticas que la interseccionalidad ha dirigido contra el marxismo tradicional. Así mostramos las posibilidades de diálogo entre estos enfoques, pero también las innegables dificultades que existen. (shrink)

Todo texto requiere de la participación del lector para completar su sentido, provocando una permanente renovación de significados con cada generación de intérpretes interrogados por nuevas cuestiones sociales, teóricas y políticas. Así, los Manuscritos de París de Karl Marx han sido objeto de discusión desde su publicación en 1932 hasta nuestros días. Si en las primeras décadas fueron leídos desde los conflictos políticos del periodo de entreguerras, de la Guerra Fría y la polémica sobre el humanismo, hoy son los debates (...) en torno al especismo, el antropocentrismo y el ecologismo los que han impulsado nuevas lecturas. En este trabajo presento las diferentes estrategias interpretativas que los autores han elaborado para tratar los principales conceptos de los Manuscritos de París desde la crítica al especismo y el antropocentrismo, contrastándolas con las estrategias de las lecturas tradicionales.

Por metodologías activas entendemos aquellas propuestas didácticas que orbitan en torno al papel del alumnado como generador de conocimiento y que construye su aprendizaje en base a la interacción con el grupo. Este planteamiento constituye la razón de ser de este trabajo donde Acción e Interacción se convierten en un grito enaltecido que llama al cambio desde la propia aula.

Na dinâmica do campo religioso brasileiro, novas formas de crer surgem, algumas religiões têm maior expansão - como algumas correntes evangélicas - e religiões tradicionais - como o catolicismo - vão-se “desencantando”. Este artigo pretende, a partir dos dados sobre religião da Pesquisa de Orçamentos Familiares (POF/IBGE, 2009), publicados em estudo da Fundação Getúlio Vargas - FGV (NERI, 2011), discutir a composição deste novo mapa religioso. Em relação às igrejas cristãs, o estudo da FGV mostrou, em termos quantitativos, a diminuição (...) do número de católicos, a estabilização do percentual de evangélicos pentecostais e o crescimento dos evangélicos não-pentecostais. Partindo da evolução histórica dos dados estatísticos sobre religião no Brasil, analisar-se-á, inicialmente, o declínio numérico do catolicismo, suas implicações e perspectivas. Em seguida buscar-se-á, através de uma análise crítica das conclusões do estudo da FGV sobre o campo protestante brasileiro, interpretar as possibilidades e os limites do uso dos dados da pesquisa para a compreensão da dinâmica do campo religioso brasileiro. Nesta via, o panorama religioso brasileiro deve ser interpretado além dos dados estatísticos. Palavras-chave: Pluralidade Religiosa. Campo Religioso Brasileiro. Catolicismo. Pentecostalismo. Demografia das Religiões.The article shows that within the Brazilian religious field new ways of believe have emerged. In this way, it also shows that some religions are in expansion – as some evangelical movements and traditional religions while some traditional religions – like Catholicism – are in a process of disenchantment. This article aims, from the 2009 Household Budget Survey – Pesquisa de Orçamentos Familiares (POF/IBGE, 2009) – data on religion published in a recent study elaborated by Fundação Getúlio Vargas (NERI, 2011), discuss the composition of this new religious map. Regarding the Christian churches, the FGV` study showed, in quantitative terms, the decrease in the number of Catholics, the stabilization of Pentecostal evangelicals’ percentage and the growth of non-Pentecostal evangelicals. Initially, based on the historical development of statistics on religion in Brazil, the numerical decline of Catholicism, its implications and perspectives will be analyzed. Basing on a critical analysis of the FGV’s study conclusions about the Brazilian protestant field numbers, the article will interpret the possibilities and limitations of using survey data for understanding the Brazilian religious field dynamics. In this way, the Brazilian religious landscape should be interpreted beyond the statistics Keywords: Religious Plurality. Brazilian Religious Field. Catholicism. Pentecostalism.

The aim of the present study is to analyze individual differences in academic self-efficacy within a population of Unaccompanied Foreign Minors from the European cities of Ceuta and Melilla. Variables describing educational level and length of stay were considered in a sample of 377 individuals being cared for in different youth centers. Of these, 63.4% belonged to the group who had stayed at the center for less than 9 months and 36.6% reported a length of stay of more than 9 (...) months. The age of participants ranged between 8 and 17 years old. Once the quality parameters of the instrument were elaborated, reliability and validity was confirmed through Confirmatory Factor Analysis using Structural Equation Modeling methodology. Data collection was then initiated. The results overall indicate that 87.6% of those who completed the questionnaire reported a higher level of self-efficacy with regards to working with any classmate, whilst at the same time seeing themselves as capable of achieving good marks. ANOVA results indicated significant differences with respect to educational level and length of stay. In this regard, students who had received professional training and had been at the Center for more than 9 months, were the ones who developed greater academic self-efficacy for spending more time working when tasks were judged to be difficult. The results obtained demonstrate that any intervention will be positive as long as it promotes different institutions to develop strategies that cater to a length of stay of more than 9 months and target education, academic self-efficacy, socialization and strengthening the future workforce. Such interventions can be directed through new European, Spanish or local level policies. It is clear that institutions still have a lot of work left to do. (shrink)

For some time now, Aristotle’s ethics – to be exact: the Nicomachean Ethics – have influenced or inspired a considerable array of theoretical options in contemporary moral philosophy. As a result, Aristotle’s ethical works have assumed a dignified systematic place next to such modern strains as the consequentialist, utilitarian or deontological ones. The precise relation of Aristotle’s ethics to these modern theories remains ambiguous, however : depending upon the particular systematic intere...

El objeto de este trabajo es estudiar la relación del filósofo francés Roland Barthes (1915-1980) con la religión, en concreto el cristianismo. Para ello, indagaremos la presencia de la religión, como objeto, como tema y como motivo, en las obras de Barthes y en algunos escritos personales suyos. En conclusión, mostraremos que el cristianismo está presente a lo largo de toda su obra y es importante desde el punto de vista de este autor.

L’article analyse la fête béotienne des Daidala dont Pausanias a conservé le souvenir (IX, 2, 7–3, 8). Tant l’aition (introduit pour expliquer pourquoi l’Héra de Platées porte l’épithète de Nympheomene) que la description de la fête dans sa double forme de Petits et Grands Daidala présentent des aspects qui méritent l’attention. Le texte présente un scénario rituel assez complexe, probablement le fruit d’une longue stratification d’éléments d’origine diverse. La description de la fête que fournit Pausanias pose une série de questions (...) touchant au statut de l’image cultuelle, aux rites pré-matrimoniaux, à l’existence d’un cycle mythique d’Héra lié aux transformations physiologiques de la parthenos, à la signification politique de la fête pour les communautés béotiennes.
