The article critically develops Nietzsche's presence in Heidegger's second great work, Contributions to Philosophy. Heidegger considers Nietzsche the last metaphysicist. However, being Western Metaphysics' zenith is the greatest thing that can be said of a thinker, since being the one who brings to completion a school of thought makes one, at the same time, the precursor of the ‘other’ begining and thus his concept of God's dead, nihilism and truth really can open the door to a kind of post-metaphysical thought, as Heidegger would say, the thought of the history od being. Therefore, between Nietzsche's "God is dead" and Heidegger's "last God" there exists continuity and parallelism that needs future development

Ganar conciencia del pluralismo en el que discurre en sus diferentes ámbitos la vida de nuestro momento histórico presupone haber aceptado que la movilidad de la existencia se da en el fluir interpretativo de todo sentido y que la verdad humana es radicalmente temporal. Vivir en un mundo determinado globalmente por imágenes fugaces de portentosa manipulación electrónica tiene que habernos sensibilizado al fluir incesante de todo sentido, cuyo sistemático desconocimiento hizo que durante tanto tiempo se desconociera y reprimiera ideológicamente la creatividad interpretativa del ser humano. En la filosofía de la segunda mitad del siglo XX, como lo vamos a bosquejar en toda brevedad, se dio, sin embargo, la rehabilitación de la interpretación en tanto que la auto-comprensión de las ciencias humanas se vio circundada de aires de liberación que resultaron de la creciente concientización de la temporalidad radical de lo humano.

ABSTRACTThis article presents the findings of a theoretically driven content analysis of the coverage of corporate social responsibility by Expansión, the leading Spanish business journal, in a 1-year time frame. The goal of the article is to help companies understand how they can take advantage of media coverage of CSR by identifying the major stakeholder groups and CSR issues discussed in business news, the positive/negative/mixed tone of the coverage, and the differences that exist in media CSR discourse depending on the industry under scrutiny. The findings are explained under the salience framework of stakeholder theory.

In western cultures, when it comes to places of worship and liturgies, music, acoustics and architecture go hand in hand. In the present study, we aimed to investigate whether the emotions evoked by music are enhanced by the acoustics of the space where the music was composed to be played on. We explored whether the emotional responses of western naïve listeners to two vocal pieces from the Renaissance, one liturgical and one secular, convolved with the impulse responses of four Christian temples from the United Kingdom, were modulated by the appropriate piece/space matching. In an alternative forced choice task where participants had to indicate their preference for the original recording of the piece (not convolved with any temple-like acoustics) vs. the convolved one, no significant differences were found. However, in the tasks where participants rated their emotional in response to each piece and acoustic condition, the factorial ANCOVA analyses performed on the results revealed significant effects. We observed that, across pieces and spaces, participants found the temple-like acoustics as more transcendent, compared to the acoustics of the original version of the pieces. In addition, they rated the secular piece as more tender and the liturgical piece as more expressive in its original versions, compared to the convolved ones. We conclude that the acoustic signature of the four Christian temples causes an exaltation of certain emotions on listeners, although this effect is not associated to one or another musical piece.

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks.

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.

El concepto de cosmovisión fue uno de los conceptos filosóficos más importantes del siglo xix. Si bien Newman no emplea la palabra Weltanschauung o Worldview, este artículo pretende mostrar dos cosas: que lo nombrado con el término cosmovisión está presente en la vida y obra del cardenal inglés, y que los criterios o notas para el genuino desarrollo de las doctrinas que propone en su Ensayo sobre el desarrollo de la doctrina cristiana pueden ser considerados para una cosmovisión racionalmente responsable como un aporte significativo a la filosofía de la religión actual.

Interest in ethical aspects associated to product acquisition and consumption is a growing trend among consumers. In this context, the concept of “product with ethical attributes” has arisen to refer to products with explicit social and environmental characteristics. However, one of the factors that most hinders the purchasing of these products is certainly price. Given the difficulty of reducing price, the question that arises is the extent to which other product attributes can attenuate the negative impact of price on perceived value. We assume that the special benefits associated to this type of products are, at a different level, attenuators of the relationship between price and perceived value. Focusing on Fair Trade organic coffee, hypotheses are tested regarding survey data from 407 customers. They were interviewed in an actual purchasing scenario. The models are tested using conventional Structural Equation Models and the Latent Moderated Structural Equation method. The results obtained shed some light on a highly generalised belief that the marketing of these products can only be improved by reducing their price. However, although a price reduction could be desirable, albeit complicated in this product category, its effects could be reduced by acting on other variables such as the ethical aspects, quality and healthiness of this product category.
