Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Aims: Attentional bias, alcohol craving, and anxiety have important implications in the development and maintenance of alcohol use disorder. The current study aims to test the effectiveness of a Virtual Reality Cue-Exposure Therapy to reduce levels of alcohol craving and anxiety and prompt changes in AB toward alcohol content.Method: A 49-year-old male participated in this study, diagnosed with severe AUD, who also used tobacco and illicit substances on an occasional basis and who made several failed attempts to cease substance misuse. (...) The protocol consisted of six VR-CET booster sessions and two assessment sessions over the course of 5 weeks. The VR-CET program consisted of booster therapy sessions based on virtual reality exposure to preferred alcohol-related cues and contexts. The initial and final assessment sessions were focused on exploring AB, alcohol craving, and anxiety using paper-and-pencil instruments and the eye-tracking and VR technologies at different time points.Results: Pre and post assessment sessions indicated falls on the scores of all instruments assessing alcohol craving, anxiety, and AB.Conclusions: This case report, part of a larger project, demonstrates the effectiveness of the VR-CET booster sessions in AUD. In the post-treatment measurements, a variety of instruments showed a change in the AB pattern and an improvement in craving and anxiety responses. As a result of the systematic desensitization, virtual exposure gradually reduced the responses to significant alcohol-related cues and contexts. The implications for AB, anxiety and craving are discussed. (shrink)

El presente trabajo parte del paralelo antitético establecido en torno al par amigo-enemigo que aparece en el “Concepto de lo político” de C. Schmitt para, a continuación, analizar las interesantes propuestas que llevan a cabo distintos autores, entre otros, H. Blumenberg, a las que añadiremos como contrapunto los representantes de la Escuela de J. Ritter, W. Böckenförde y H. Lübbe. En especial señalamos el tránsito que se produce de la neutralidad a la neutralización, a partir de la nueva consideración de (...) la temporalidad que se produjo a comienzos del Siglo XVI. Sin embargo, de esta paradójica constitución surgirán una serie de mitos correlativos a la neutralización que la refuerzan, por lo que nos referimos, finalmente, al status quo y al regreso, que constituyen los ecos metáforicos del moderno binomio progreso-regreso.

El autor sigue desplegando su línea interpretativa de la recepción de Vico en España a la luz de una lectura diferencial. Como continuación a su anterior estudio "Nuevos aportes (históricos y filosóficos) para la fortuna de Vico en el siglo XIX español" (Cuadernos sobre Vico, 5/6, 1995-96), se realiza una relectura de la modernidad viquiana a través de la recepción en Juan Donoso Cortés, proponiendo una clave hermenéutica mediante la cual es posible comprender además de la imagen moderna de Vico, (...) reflectada tanto en la asunción cuanto en el abandono del napolitano por Donoso, también la bifronte posición donosiana frente a su siglo: un "primer Donoso", ilustrado, liberal y ecléctico; y un "segundo Donoso", reaccionario y tradicionalista. El mismo caso de la recepción de Vico se muestra así concluyente como un elemento más con el que poder interpretar el siglo XIX español a través de los dos lenguajes de tradición y progreso.

The present work consists on figuring out the problematic relationships between the Logic of the Period of Jena and the internal emergence of a Dialectical one to the own system. Dialectical is more than a simple general methodology of the knowledge.

Este artículo rastrea el origen fenomenológico de las imágenes en el momento presente. Para ello, se considera la imagen singular y su fuerza generatriz reflejada en dos propuestas no-duales: la de Spinoza, donde los afectos constituyen activamente la realidad como respuesta ética relativa al cuidado; y la de Gilligan cuya ‘ética del cuidado’ construye una personalidad genuina capaz de producir una imagen no-dual de nuestro yo a través de una identidad creativa y libre de prejuicios. Finalmente, se presenta un ejemplo (...) visual que sintetiza la potencia ética de la imagen y su relación con el cuidado. (shrink)

Un estudio breve sobre la línea Vico-Boturini-Mayans, a propósito de las nuevas aportaciones realizadas en tres escritos de Antonio Mestre.

It can be stated that self-regulated learning (SRL) brings broad benefits to the process of students' learning and studying. However, research has yet to be undertaken in relation to one of its components, namely self-regulation of motivation and affectivity. The main objectives of this study are to examine the use of self-motivation strategies that involve classmates and to obtain models on the influence of academic goals and self-efficacy on such self-motivation strategies. To this end, was conducted a study using two (...) different samples of students in the compulsory secondary education or baccalaureate stages in Spain (N = 613 and N = 910). The results obtained indicate that, with regard to gender, differences only exist in the use of the strategy of deception (t = 5.450, p <.001, d =.364). That the two pairs of strategies positively and significantly correlated with one another (r =.239, p <.01 and r =.355, p <.01). That only the strategy of annulation of others correlates with a more adaptive type of motivation. Thus, the group of students that reported the greatest level in its use also did so in relation to task and ego self-enhancing goals, to self-efficacy, and being negatively associated with the goal of work avoidance. Finally, were offered models on relationships between academic goals, self-efficacy and enhancement and annulation strategies (χ² (8) = 5.204, p =.736) and deception and annulation strategies (χ² (4) = 3.228, p =.520).

Review of J.S.Mill: _Capítulos sobre el socialismo. Civilización._ Edición de Carlos Mellizo. Madrid, Alianza Editorial, 2012.

En este ensayo el autor pone en directa relación la Digresión acerca del ingenio humano, las agudezas y ocurrencias y la risa que con tal motivo se origina, incluida en las Vici Vindiciae de Vico, con las tesis de la Ciencia nueva acerca de la facultad “verdadera” del ingenio y del carácter exclusivo humano de la risa. Con ello, la risa –junto al ingenio–se nos presenta como un elemento clave en la cadena de conquista de humanidad: el que representa el (...) paso del ‘hombre bestial’ al ‘hombre humano’ (“uomo ridente”).

In other work, I have explored what is political about intrafamilial violence. I claimed that intrafamilial violence is political not only because it involves violating human rights but, more fundamentally, because social structures contribute to its explanation. Exploring what is political about intrafamilial violence allows us to identify two crucial features. First, the structural explanation suggests that the political community’s social practices contribute to the broader context that gives meaning to intrafamilial violence as a tool for control. Accordingly, it is (...) not just the offender but the political community that should also be called to account. Second, it shows that intrafamilial violence, as a tool for control, undermines not just the body but the social power of the victim while simultaneously empowering the offender. This paper examines these features in more detail and shows their importance for criminal law theory, namely, as reasons for justifying criminalising intrafamilial violence. (shrink)

Este libro es una apuesta por una razón problemática, una síntesis de aquello que en concreto es razón narrativa y en abstracto se denomina "razón histórica". Se trata de una nueva perspectiva que despliega el ejercicio de una crítica acorde con las exigencias del presente. Además, examina las verdades recibidas, analiza su propia condición (modificacional) y constitución (histórica) y desvela un íntimo sentido a través de sus quehaceres. Problematismo, crisis, mutabilidad y cambio son los elementos inherentes a la naturaleza histórica (...) de la vida del hombre. La célebre afirmación orteguiana de que el hombre, en vez de naturaleza, lo que tiene es historia no sólo es expresión de un historicismo que remite tanto a Giambattista Vico como a José Ortega y Gasset, sino la matriz de toda filosofía centrada en la concreción de la existencia humana individual. En este sentido, se concibe un indeleble vínculo entre problematismo de lo real y reflexión filosófica, y una indisoluble complementación entre filosofía e historia, razón y narración, verdad y certeza. Motivado así por las originales ideas de ambos pensadores modernos y actuales, el autor indaga y esgrime una crítica de la razón problemática, y amplía los horizontes de la razón vital, histórica y narrativa que arraigan en la realidad del vivir y en la radicalidad del filosofar. Dirige asimismo su mirada hacia el constitutivo ontológico de la problematicidad, el carácter del filósofo, los espacios y los modos de la filosofía. (shrink)

Proponemos que ciertos “detalles” (la catálisis, según Barthes) revelan la presencia del poder disciplinario en la esfera del relato moderno. Iniciamos el análisis a partir de algunas unidades descriptivas del Purén Indómito, a las que consideramos antecedentes directos de esa revelación, y concluimos con la novela Martín Rivas y el cuento El matadero. El texto colonial da cuenta detallada de la vida cotidiana en el reino de Chile, cuenta que expresa las estrategias del poder de soberanía, mientras que en los (...) relatos modernos relevará la presencia del poder disciplinario. Así, la presencia de detalles dramáticos en el Purén obedece a lograr la intervención jurídica-moral del monarca en el reino. En cambio, a partir del realismo esos detalles muestran el actuar de los cuerpos a someter y disciplinar, tal y como ocurre en Martín Rivas y El matadero. La estrategia narrativa será entonces sacar a la luz los detalles de las costumbres retrógradas, bárbaras, sucias, de la sociedad latinoamericana para disciplinarlas, limpiarlas y conseguir, así, naciones modernas y productivas. Our proposition is that certain “details” (catalysis, according to Barthes) reveal the presence of disciplinary power in the sphere of modern fiction. Our analysis starts with some of the descriptive units of Purén Indómito, which we consider to be a direct precedent for this revelation, and we conclude with the novella, Martín Rivas, and the short story, El matadero. The text dating from the colonial period gives a detailed account of daily life in the kingdom of Chile, describing the strategies of the sovereign power, while the modern stories highlight the presence of disciplinary power. Thus, the purpose of the dramatic details recounted in Purén is to ensure the legal-moral intervention of the monarch in the kingdom. In realist works, on the other hand, these details show the actions of organisations to subject and discipline the people, just as it occurs in Martín Rivas and El matadero. In this case, the narrative strategy is to exhibit the details of the foul, barbarous, reactionary customs of Latin American societies in order to discipline and purify them, and thus transform them into modern, productive nations.

Resumen: En este ensayo desarrollo una crítica al modelo de justicia multicultural de Will Kymlicka, con el propósito de establecer las bases para el desarrollo de un multiculturalismo crítico. El argumento se ordena de la siguiente forma. En la primera sección analizo la teoría de los derechos especiales de Kymlicka e identifico el valor liberal central al que estos responden, la autonomía individual. En la segunda sección examino el fundamento igualitarista de la suerte de su teoría de los derechos especiales. (...) En la tercera sección elaboro una crítica general a la justicia multicultural liberal desarrollando un argumento para politizar los reclamos de los pueblos indígenas para el acceso a su cultura. Argumento que el trato justo de las minorías indígenas requiere reconocer su autodeterminación política.: In this essay I develop a critique of Will Kymlicka’s model of multicultural justice, with the purpose of laying down the foundations for a critical multiculturalism. The argument is ordered in the following way. In the first section I analyse Kymlicka’s theory of special rights and identify the central liberal value to which they respond: individual autonomy. In the second section I examine the luck egalitarian foundations of Kymlicka’s theory of special rights. In the third section, I elaborate a general critique to liberal multicultural justice, developing an argument to politicize the claims of indigenous peoples to access to their culture. Basically I argue that the just treatment of indigenous minorities requires recognizing their political self-determination. (shrink)

Localization Wireless Sensor Networks (WSN) represent a research topic with increasing interest due to their numerous applications. However, the viability of these systems is compromised by the attained localization uncertainties once implemented, since the network performance is highly dependent on the sensors location. The Node Location Problem (NLP) aims to obtain the optimal distribution of sensors for a particular environment, a problem already categorized as NP-Hard. Furthermore, localization WSN usually perform a sensor selection for determining which nodes are to be (...) utilized for maximizing the achieved accuracy. This problem, defined as the Sensor Selection Problem (SSP), has also been categorized as NP-Hard. While different metaheuristics have been proposed for attaining a near optimal solution in both problems, no approach has considered the two problems simultaneously, thus resulting in suboptimal solutions since the SSP is biased by the actual node distribution once deployed. In this paper, a combined approach of both problems simultaneously is proposed, thus considering the SSP within the NLP. Furthermore, a novel metaheuristic combining the Black Widow Optimization (BWO) algorithm and the Variable Neighbourhood Descent Chains (VND-Chains) local search, denominated as BWO-VND-Chains, is particularly devised for the first time in the author’s best knowledge for the NLP, resulting in a more efficient and robust optimization technique. Finally, a comparison of different metaheuristic algorithms is proposed over an actual urban scenario, considering different sensor selection criteria in order to attain the best methodology and selection technique. Results show that the newly devised algorithm with the SSP criteria optimization achieves mean localization uncertainties up to 19.66 % lower than traditional methodologies. (shrink)

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)
