Neuroscience research has shown that meditation practices have effects on brain structure and function. However, few studies have combined information on the effects on structure and function in the same sample. Long-term daily meditation practice produces repeated activity of specific brain networks over years of practice, which may induce lasting structural and functional connectivity changes within relevant circuits. The aim of our study was therefore to identify differences in FC during the resting state between 23 Sahaja Yoga Meditation experts and (...) 23 healthy participants without meditation experience. Seed-based FC analysis was performed departing from voxels that had shown structural differences between these same participants. The contrast of connectivity maps yielded that meditators showed increased FC between the left ventrolateral prefrontal cortex and the right dorsolateral prefrontal cortex but reduced FC between the left insula and the bilateral mid-cingulate as well as between the right angular gyrus and the bilateral precuneus/cuneus cortices. It thus appears that long-term meditation practice increases direct FC between ventral and dorsal frontal regions within brain networks related to attention and cognitive control and decreases FC between regions of these networks and areas of the default mode network.

: This response to Nikolaus Knoepffler's paper in the same issue of the Journal agrees that if the arguments supporting the first two of the eight human embryonic stem cell research policy options discussed are unsound, as Knoepffler argues, then it seems natural to move to the increasingly permissive options. If the arguments are sound, however, then the more permissive options should be rejected. It is argued that three of the rejected arguments, taken together, constitute very good reasons to hold (...) that a human embryo is endowed with dignity from fertilization onward. Thus, countries that want their public policies to match the moral imperative of respect for human beings should refrain from allowing destructive human embryo research and should devote considerable energy and public funds to research and clinical trials using non-embryonic ("adult") stem cells.

This paper presents the hypothesis that linguistic capacity evolved through the action of natural selection as an instrument which increased the efficiency of the cultural transmission system of early hominids. We suggest that during the early stages of hominization, hominid social learning, based on indirect social learning mechanisms and true imitation, came to constitute cumulative cultural transmission based on true imitation and the approval or disapproval of the learned behaviour of offspring. A key factor for this transformation was the development (...) of a conceptual capacity for categorizing learned behaviour in value terms - positive or negative, good or bad. We believe that some hominids developed this capacity for categorizing behaviour, and such an ability allowed them to approve or disapprove of their offsprings- learned behaviour. With such an ability, hominids were favoured, as they could transmit to their offspring all their behavioural experience about what can and cannot be done. This capacity triggered a cultural transmission system similar to the human one, though pre-linguistic. We suggest that the adaptive advantage provided by this new system of social learning generated a selection pressure in favour of the development of a linguistic capacity allowing children to better understand the new kind of evaluative information received from parents.

The purpose of this research is the analysis of a specific cultural and political tension, through two decisive concepts: imagocracy and imagomaquia. Our aim is to define the political battlefield in the arena of audiovisual communication. In the case of Latin America, we have identified two significant moments, in which the popular audiovisual strategies had crucial importance. Our material of research has been both the New Latin American Cinema and the sociology of the decolonial image. We have studied them in (...) depth in order to define the effectiveness of popular audiovisual strategies as nuclei of creation and aesthetic-political resistance, which opposes the hegemonic audiovisual order.

El presente artículo es un estudio teórico sobre las similitudes entre las doctrinas gnósticas, que florecieron alrededor del siglo ii de nuestra era, y el pensamiento estético del pintor ruso Vasili Kandinsky. El objetivo es analizar estos dos marcos de ideas filosóficas y espirituales para exponer sus similitudes y diferencias. De esta manera, se indagará si, pese a los siglos que las separan y la diferencia de contextos históricos que las rodean, pueden existir en los orígenes de ambas propuestas doctrinales (...) unas problemáticas existenciales y filosóficas comunes. El estudio buscará, con ello, dilucidar si es posible entender la estética de Kandinsky como una especial gnosis moderna estructurada a través de sus planteamientos conceptuales y artísticos. Los resultados de la investigación pretenden no solo dar luces sobre la originalidad de Kandinsky dentro de la historia del arte, sino que también llegar a ser útiles para resaltar y comprender algunos puntos importantes de la discusión cultural dentro de la cual se enmarca su obra.

La relación que Ricoeur establece entre lo bueno, lo justo y la convicción permite postular un círculo hermenéutico —semejante al que Heidegger propone en su ontología fundamental, y que Gadamer complementa en Verdad y método— en la filosofía práctica, conformado por tres momentos: lo bueno, lo justo y su aplicación al contexto que lo demanda. Con su “pequeña ética”, mediada por esta reformulación, Ricoeur pretende terciar en la discusión entre la ética de la argumentación de Habermas y el comunitarismo e (...) historicismo de C. Taylor, A. MacIntyre y H.-G. Gadamer. (shrink)

Encaminharemos neste artigo algumas considerações que nos permitam esboçar uma ontologia não-antropocêntrica. O artigo se divide em cinco partes. Na primeira, recorremos a Meillassoux para situar o antropocentrismo como base fundamental dos correlacionismos. Em seguida, apresentamos o materialismo vital de Jane Bennett como alternativa não-antropocêntrica às filosofias correlacionistas. Na terceira seção, recuperamos a noção espinosista de corpos afetivos para pensar uma ontologia plana relacional. Na sequência, apresentamos o perspectivismo relacional afetivo de Nietzsche como alternativa ao idealismo kantiano. E por fim, (...) trazemos a noção de agenciamento como noção chave para a composição de uma ontologia não-antropocêntrica. (shrink)

La participación ciudadana en España ha experimentado en las últimas décadas un profundo proceso de cambio. La globalización y un estilo de vida individualista y pasivo han debilitado la sociedad civil, promoviendo una participación light. El autor realiza una tipología realista y crítica, y después nos muestra los caminos de una acción colectiva renovada, eficaz dentro de un mundo nuevo que se nos presenta con muchos retos y dificultades y en el que no podemos permanecer sin hacer nada.The civil participation (...) in Spain has experienced in the last decades a deep process of change. The globalization and an individualistic and passive way of life have debilitated the civil society, promoting a light participation. The author realizes a realistic and critical typology, and later he shows us the ways of a collective action renewed, effective inside a new world that us one presents with many challenges and difficulties and in which we cannot remain without doing anything.

Empreende-se nesse artigo a tentativa de compreender as bases psíquicas do autoritarismo político contemporâneo. Através dos conceitos freudianos de “pulsão de poder” (Bemächtigungstrieb) e projeção, oferecemos uma hipótese para o inquietante fenômeno contemporâneo da adoração a líderes autoritários.

Our aim in this paper is to propose an ontology for numbers that is compatible with an epistemology that does not invoke mysterious faculties. On the basis of my explanatory system, we find objects capable of being classified: horses, colors, etc. Once grouped, they can be reclassified in units, pairs, and so on. When they use expressions like “three horses”, in fact, I believe that what they mean is “a threesome of horses”. I call nonmathematical numbers those reclassification, and I (...) suggest that arithmetical numbers could be regarded as pictures of nonmathematical numbers, that are closely connected with empirical facts.

The aim of this article is to analyze how the Spanish newspapers covered an international event such as the Egyptian spring from 2011 to 2013. From the perspective of the representation of Arab-Islamic issues, this study carries out a quantitative content analysis on the four reference newspapers in Spain (ABC, El Mundo, El País, and La Vanguardia) to find out whether there was an Islamophobic or Islamophilic treatment during the Egyptian revolution. The results of the 3,045 articles analyzed show that (...) Spanish newspapers were remarkably interested in Egyptian events and that cultural discourses were not relevant in the coverage. However, it is necessary to specify these outcomes by newspaper, because each paper proposed its own take on the matter based on information provided by press agencies. (shrink)
