El propósito de este artículo es mostrar el sentido de la risa del filósofo Zaratustra en la obra de Friedrich Nietzsche. Su risa expresa una actitud filosófica y posee tres características: es signo de la sabiduría trágica, síntoma de una forma de vida saludable y una herramienta para la crítica de los ideales que dañan la vida. Concluimos el artículo considerando que la risa y la comedia es el necesario punto de llegada de la concepción dionisíaca del mundo.

¿Cuál es la relación entre la ciencia y sus métodos y la genealogía? La respuesta a esta pregunta es el propósito fundamental de este artículo. Para ello, llevaremos a cabo un triple análisis de la cuestión, expuesto en un orden de menor a mayor profundidad y radicalismo teórico: primero, mostraremos el modo como la ciencia es utilizada por la crítica genealógica; segundo, desarrollaremos la crítica genealógica de la ciencia, y, tercero, consideraremos la pretensión de Nietzsche de establecer un nuevo criterio (...) para valorar el conocimiento en general y el científico en particular.

El punto de partida de este artículo es la crisis del concepto de ciudadanía ante los cambios sociales y políticos de nuestras sociedades. Trataré aquellos problemas de la ciudadanía causados por el carácter multiétnico, multicultural y plurinacional de las sociedades actuales y por las demandas de lo que se ha venido a llamar "multiculturalismo" y por las del nacionalismo. También este artículo intenta ofrecer una clasificación de los tipos de ciudadanía y un criterio que nos permita distinguir entre los tipos (...) de ciudadanía aceptables y los inaceptables The concern of this article is with the crisis of the concept of citizenship due to the social and political changes taking place in our societies. I shall focus on those problems caused by multiethnic, multicultural and multinational nature of present societies and by demands of nationalism and what has come to be know as the politics of "multiculturalism". These pages attempt to offer a taxonomy of citizenship types as well as a criterion by which to distinguish between acceptable and unacceptable varieties of citizenship. (shrink)

Detecting intrusions in large networks is a highly demanding task. In order to reduce the computation demand of analysing every single packet travelling along one of such networks, some years ago flows were proposed as a way of summarizing traffic information. Very few research works have addressed intrusion detection in flows from a visualizations perspective. In order to bridge this gap, the present paper proposes the application of a novel projection method (Beta Hebbian Learning) under this framework. With the aim (...) to validate this method, 8 traffic segments, containing many flows, have been analysed by means of this projection method. The promising results obtained for these segments, extracted from the University of Twente dataset, validate the proposed application. (shrink)

La primera parte de este artículo discute el poder persuasivo de las narrativas, especialmente en historia de la filosofía, ligándolas con la oposición entre razón y emoción y también con el conocido tema rortiano de las redescripciones. Además, presenta brevemente las líneas generales de la reconstrucción histórica hecha por Rorty y la tipología de géneros historiográficos que establece. La segunda parte muestra ejemplos del modo en que Rorty usa la persuasión al elaborar dos de tales géneros: las reconstrucciones históricas y (...) las reconstrucciones racionales. The first part of this paper discusses the persuasive power of narratives, especially when applied to history of philosophy, linking it with the opposition between reasons and emotions, and with the well-known rortyan theme of redescriptions. It also presents briefly the outlines of the historical reconstruction made by Rorty and the typology of historiographical genres established by him. The second part shows some examples of the way Rorty uses persuasion to develop two such genres: historical reconstructions and rational reconstructions. (shrink)

Different theoretical approaches highlight the growing relevance of corporate reputation as strategic factor. Among these approaches the arguments of the Resource-Based View are special worthwhile (Grant, 1991, California Management Review33(3), 114–135; Barney, 1999, Sloan Management Review Spring, 137–145). Nevertheless, this topic poses several methodological problems (Barney et al., 2001), as the unavailability to identify and measure this organizational factor, that is “socially complex” and intangible in its nature. In this work, using the findings of our empirical research on Spanish biotechnology (...) firms, we carry out an identification and measurement of corporate reputation, highlighting its two key components: “business reputation” and “social reputation”.

El presente artículo tiene como objetivo develar la implicación de los nexos entre la cultura y los procesos de comprensión y desarrollo psíquico para la concepción e instrumentación de una enseñanza desarrolladora atendiendo a que el desarrollo psíquico del sujeto es una condición esencial para lograr su papel activo y creador en el desarrollo social. Por ello su tránsito a niveles cualitativamente superiores, constituye una prioridad para los sistemas educativos. La teoría histórico - cultural del desarrollo psíquico le da especial (...) importancia al papel de la cultura y su asimilación en la formación y desarrollo de la personalidad. Además, disciplinas como la semiótica reconocen el papel del texto y los procesos textuales en la conservación, transmisión y re-creación de la cultura. El estudio realizado se basa en la sistematización de postulados básicos de la teoría histórico - cultural del desarrollo psíquico y la semiótica de la cultura. This article aims at revealing the implications of the links between culture and the processes of understanding and psychic development towards the conception and implementation of developmental teaching taking into account that an individual's psychic development is an essential condition to fulfil its active and creative role in social development. That is why its movement to qualitatively superior levels is a priority for educational systems. The historical-cultural theory gives special importance to the role of culture and its assimilation in the formation and development of the personality. Furthermore, disciplines such as semiotics recognize the role of texts and textual processes in the conservation, transmission and recreation of culture. This study is based on the systematization of basic postulates of the historical-cultural theory of psychic development and Culture Semiotics. (shrink)

A large part of technological advances, especially in the field of industry, have been focused on the optimization of productive processes. However, the detection of anomalies has turned out to be a great challenge in fields like industry, medicine or stock markets. The present work addresses anomaly detection on a control level plant. We propose the application of different intelligent techniques, which allow to obtain one-class classifiers using real data taken from the correct plant operation. The performance of each classifier (...) is assessed and validated with real created faults, achieving successful overall results. (shrink)

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing (...) data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

The use of batteries became essential in our daily life in electronic devices, electric vehicles and energy storage systems in general terms. As they play a key role in many devices, their design and implementation must follow a thorough test process to check their features at different operating points. In this circumstance, the appearance of any kind of deviation from the expected operation must be detected. This research deals with real data registered during the testing phase of a lithium iron (...) phosphate—LiFePO4—battery. The process is divided into four different working points, alternating charging, discharging and resting periods. This work proposes a hybrid classifier, based on one-class techniques, whose aim is to detect anomalous situations during the battery test. The faults are created by modifying the measured cell temperature a slight ratio from their real value. A detailed analysis of each technique performance is presented. The average performance of the chosen classifier presents successful results. (shrink)

Los poemas históricos de Ships in Bottles de Neil Curry ofrecen una oportunidad de hacer una reflexión sobre la posible vigencia de la teoría del gran hombre. Contrasta la desconsideración que dicha aportación de Carlyle tiene en la actualidad con su seguimiento en otros campos, como los negocios o la política. En el caso de la poesía, los poemas seleccionados hacen ver de qué manera los grandes actantes de la historia conviven con las personas que hacen la microhistoria.

Automatic control of physiological variables is one of the most active areas in biomedical engineering. This paper is centered in the prediction of the analgesic variables evolution in patients undergoing surgery. The proposal is based on the use of hybrid intelligent modelling methods. The study considers the Analgesia Nociception Index to assess the pain in the patient and remifentanil as intravenous analgesic. The model proposed is able to make a one-step-ahead prediction of the remifentanil dose corresponding to the current state (...) of the patient. The input information is the previous remifentanil dose, the ANI variable and the electromyogram signal. Modelling techniques used are Artificial Neural Networks and Support Vector machines for Regression combined with clustering methods. Both training and validation were done with a real dataset from different patients. Results obtained show the potential of this methodology to calculate the drug dose corresponding to a given analgesic state of the patient. (shrink)

El movimiento transhumanista tiene, entre sus propuestas principales, el proyecto de alargar la vida para poder alcanzar la inmortalidad en una vida indefinida o en una forma cibernética de existencia. En este artículo se presenta la propuesta del transhumanismo y se reflexiona sobre el deseo de ser inmortales y sobre las implicaciones antropológicas de la muerte. La crítica se hace desde la consideración de aspectos fundamentales del ser humano, como la finitud, la historicidad y la vulnerabilidad. Además, el proyecto transhumanista (...) de vencer la muerte supone una propuesta de salvación, que coincide en su formulación con la misma que hace el cristianismo. Ambos pretenden una victoria sobre la muerte. La crítica teológica se centra en la comprensión de la muerte y en la reflexión sobre los medios para vencerla. En este artículo la crítica al proyecto transhumanista se dirige, más que a lo que propone, a lo que queda sin plantear, provocando una reducción en la comprensión de la muerte y en la forma de vencerla.

Some transhumanist authors make the prophecy of immortality thanks to the transfer of the human mind to a superintelligent computer that would guarantee the survival of the person. That immortality would mean a happy life. In this article we try to show that this supposed indefinite survival is not exactly what is usually understood by immortality. In addition, we try to think about what immortality is based on the theological understanding of eternity and personal communion in which the life of (...) God consists. The decisive questions in this dialogue with the postures of transhumanism are the meaning of the body for the human person and what happiness is. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

"Ay, no quieres, te asusta la pobreza: no quieres ir con zapatos rotos al mercado y volver con el viejo vestido" dice Pablo Neruda en uno de los poemas de su libro "Los versos del capitán".

Algunos estudios se han centrado en las controversias que surgieron hace casi dos décadas cuando se aprobaron los libros de texto de historia revisados, materiales didácticos que fueron de uso muy minoritario en Japón. Teniendo en cuenta este antecedente y desde un enfoque cualitativo, se realiza una investigación de análisis de fuentes documentales con el objetivo de comprender la representación de temas sensibles en los libros de texto de historia de Japón de uso mayoritario en relación con la expansión por (...) el este asiático y la Segunda Guerra Mundial. Para ello, tras seleccionar los libros de texto de historia japonesa de la prefectura de Tokio más utilizados en las escuelas secundarias, se realiza un análisis documental comparativo. Este análisis se estructura en una serie de categorías que incluyen algunos episodios sensibles de la Segunda Guerra Sino-Japonesa y la guerra de Asia-Pacífico. Esta investigación concluye que en los libros de texto de historia japoneses se incluyen contenidos considerados controvertidos desde una perspectiva predominantemente aséptica. (shrink)

C’est à Disidentification : Queers of Color and the Performance of Politics de José Esteban Muñoz que l’on doit la diffusion du concept de désidentification. L’historien de l’art l’utilise pour désigner ces artistes queers noir·es et latinx qui ont développé des techniques pour ne pas répondre à l’injonction institutionnelle à produire un art « ethnique » ou estampillé « queer ». Dans cet extrait, le minimalisme de Felix González-Torres permet d’aborder la désidentité sous la forme d’œuvres qui déjouent (...) les interpellations stigmatisantes du multiculturalisme tout en s’adressant au contre-public des allié·es.
