The utopian energy of the liberal social-democratic state, which is unable to answer the great questions of today's world, is now spent. The way forward will involve a struggle, not against the institutions, but for the emergence of a new rationality, corresponding not only to a new organisation of society, but also to a strategic and multidimensional concept of class.

A lo largo de la historia la ciudad ha constituido el espacio por excelencia de la democracia. Esta es la razón por la que reconstruyendo la cambiante funcionalidad de los espacios urbanos podemos rastrear la genealogía de la esfera pública. Este artículo aborda el estudio de las prácticas democráticas a través de los lugares de la ciudad en los que se han desarrollado, particularmente las plazas públicas. Las plazas se presentan desde esta perspectiva como un espacio agonístico añadido a las (...) instituciones formales de representación política. (shrink)

El estudio de la etnicidad ha presentado tradicionalmente una serie de dificultades. La razón última de ello estriba en la naturaleza dinámica y difusa de las identidades sociales. Este artículo reconstruye el origen intelectual de tales dificultades y la importancia de la idea de contingencia para una consideración normativa de la etnicidad. Tras repasar los principales modelos de ciudadanía moderna, el texto analiza el papel de los inmigrantes en la estructura de derechos civiles y concluye con una reflexión sobre las (...) posibilidades abiertas en la sociedad española para un modelo pluralista de integración.

Although gains in generational intelligence test scores have been widely demonstrated around the world, researchers still do not know what has caused them. The cognitive stimulation and nutritional hypotheses summarize the several diverse potential causes that have been considered. This article analyses data for a sample of 499 children tested in 1930 and one equivalent sample of 710 children tested 72 years later, the largest gap ever considered. Both samples comprised children aged between 7 and 11 who were assessed by (...) the Draw-a-Man test in the city of Belo Horizonte, Brazil. Further, one additional sample of 132 children was assessed in 2004 in a rural area very similar in several diverse factors to the 1930 urban sample. The results are consistent with both the cognitive stimulation and the nutritional hypotheses. (shrink)

The microbiota-gut-brain axis field is at an exciting stage, but the most recent developments in microbiota research still have to find their way into MGB studies. Here we outline the standards for microbiome data generation, the appropriate statistical techniques, and the covariates that should be included in MGB studies to optimize discovery and translation to clinical applications.

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

El artículo presenta una aproximación a la transición educativa, laboral, domiciliar y familiar de las personas jóvenes desde la perspectiva de género. El objetivo es analizar hasta qué punto la mejora del nivel educativo introduce transformaciones en el carácter tradicionalmente sexuado de las transiciones hacia la vida adulta. El análisis parte del conjunto de factores estructurales que pueden condicionar las transiciones juveniles, si bien atribuye una influencia central a la etapa del ciclo vital. A partir de los datos de la (...) Enquesta a la Juventud de Catalunya 2012, se concluye que el efecto ciclo vital limita el efecto generacional en la transformación de las relaciones de género entre la población joven.This paper focuses on educational, employment, housing and family transitions of young people from the gender perspective. The aim is to analyze how the educational system introduces changes in the traditional gendered transitions to adulthood. For this purpose, it takes into account structural factors with special attention to the life cycle. Based on data from the Enquesta a la joventud de Catalunya 2012, the results show that the effect of life cycle limits the effect of the generation in order to change the gender relations between young people.

This study aimed to investigate whether the ordinal judgments of high math-anxious and low math-anxious individuals differ. Two groups of 20 participants with extreme scores on the Shortened Mathematics Anxiety Rating Scale had to decide whether a triplet of numbers was presented in ascending order. Triplets could contain one-digit or two-digit numbers and be formed by consecutive numbers, numbers with a constant distance of two or three or numbers with variable distances between them. All these triplets were also presented unordered: (...) sequence order in these trials could be broken at the second or third number. A reverse distance effect of equal size was found in both anxiety groups. However, HMA participants made more judgment errors than their LMA peers when they judged one-digit counting ordered triplets. This effect was related to worse performance of HMA individuals on a symmetry span test and might be related to group differences on working memory. Importantly, HMAs were less accurate than LMA participants at rejecting unordered D2 sequences. This result is interpreted in terms of worse cognitive flexibility in HMA individuals. (shrink)

It is an intimate experience for us to think, to understand and to perceive things as being identical to themselves, and to suppose, consequently, that things are truly “what” they are. Something is always conceived as itself. The given is given full of itself in all its modifications. For instance, I can think or perceive partially some lips, I can see them almost in their whole or in some of their aspects, or just see them disappear. But it does not (...) seem to be possible to think or to perceive a given as almost itself, as an aspect or as part of itself. It is the aim of this work to study the assumptions and conditions for the original position of sameness in experience, just as it occurs in the synthesis of the datum singular and distinct. The polarization of single tone (einstimmig) intentional rays in an αvτó already contains the aporiae peculiar to the experience of the identical, whose revelation shall lead us, on the one hand, to one of the nuclei of the analysis of passive synthesis, and, on the other hand, to point up how critical revision of the numerical or extensional model of self-identity is for the unity of meaning. Then, it will be a question of pointing out the reasons why in a phenomenology of identity, the renunciation of the phenomenological legitimacy of the αvτó as a guarantee for the different positions of identity must be observed.

Con el fin de desentrañar el papel que las más actuales corrientes filosóficas desempeñan en la educación, los autores de este libro parten de un crítico análisis de los acontecimientos de mayo del 68.Se intuyen dos vías de intervención de la filosofía sobre el pensamiento y la práctica educativa: por un lado, la tendencia anti constructivista a los discursos posmodernos, sistémicos y tecnológicos ; por otro, la persistencia del humanismo asentado ahora en el intento de prolongar la modernidad" y en (...) nuevas perspectivas tales como el pacifismo y el ecologismo.

O presente volume reune quase uma trintena de artigos com temas culturais, de consagrados autores portugueses e brasileiros, que assim pretenderam homenagear o Professor. oordenada por Joaquim Gonçalves, a obra é estruturada em 4 partes. As três primeiras agrupam as intervenções, consagrando-se a quarta à vida e obra do homenageado.

En el particular contexto filosófico de la Alemania de entreguerras, el joven H. Marcuse llevó a cabo una original recepción en clave marxista de la fenomenología existencial y de la Lebensphilosophie (I). En sus primeros artículos, «Contribuciones a una fenomenología del materialismo histórico» (1928) y «Sobre filosofía concreta» (1929), esa recepción se orientó al proyecto de elaboración de una fenomenología dialéctica y, vinculado con ello, al intento de fundamentar la acción radical en el concepto ontológico de historicidad (Geschichtlichkeit) sin descuidar (...) su componente material (II, III, IV). Asimismo, en la situación de caída (Verfallen) del Dasein, Marcuse va a otorgar una misión primordial a la filosofía concreta (V). (shrink)

The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence (...) of the three necessary, and jointly sufficient, conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgements; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequece of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection.
