In this work, we present a new approach to solve the location management problem by using the reporting cells strategy. Location management is a very important and complex problem in mobile computing which aims to minimize the costs involved. In the reporting cells location management scheme, some cells in the network are designated as reporting cells . The choice of these cells is not trivial because they affect directly to the cost of the mobile network. This article is focused on (...) the use of high performance computing to execute a parallel heuristic that places optimally the RCs in a mobile network, minimizing its total cost. The main goal of this work is to demonstrate that the collaborative work of different evolutionary algorithms can obtain very good results. For this reason, we have implemented a parallel heuristic and six evolutionary algorithms that works in a parallel way on a cluster to solve the RCs problem. (shrink)

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

Este artículo analiza ciertas interpretaciones del célebre comentario de Wittgenstein a Drury, sin duda relevantes para comprender el sentido de la filosofía del pensador vienés en su último periodo, según el cual él mismo, sin ser una persona religiosa, no podía evitar contemplar todas las cuestiones desde una perspectiva religiosa. Los pasos para identificar la razón por la que se puede afirmar que la inmunización de la forma de vida religiosa constituye el sentido último de la filosofía concebida como análisis (...) de los juegos de lenguaje serán, en primer lugar, poner en relación el valor supremo de la claridad con la crítica de la actitud explicativa característica de la filosofía convencional y, en segundo término, considerar el análisis del discurso religioso y la peculiar religiosidad del propio Wittgenstein. This paper explores some of the issues related to Wittgenstein's famous comment to Drury -that he himself, while not a religious person, could not avoid contemplating all questions from a religious perspective- that might contribute to an understanding of the final meaning of the philosophical practice distinctive of Wittgenstein's last period. This paper aims at showing that final meaning is the immunization of the religious form of the life. In order to reach this conclusion we will first recall the importance of clarity as an absolute goal of Wittgenstein's philosophy, and see how it is connected to a specific attitude toward the explanatory claims of conventional philosophy. Then we will summarize the essence of Wittgenstein's philosophical analysis of religious discourse and review some crucial texts that highlight the peculiar religiosity unique to Wittgenstein.

Resumen: A partir del último libro de La gaya ciencia en este trabajo procedo, en primer lugar, a fijar los rasgos del nuevo entendimiento nietzscheano de la creencia en cuanto un determinar activo contrapuesto a la pretensión de verdad entendida como corrección o ajuste de la representación, es decir, en cuanto contracreencia. En segundo lugar, caracterizo a grandes rasgos lo que hay que considerar como creencia específicamente nietzscheana, constitutiva del sentido nuclear de su producción filosófica. Debemos denominar "fe dionisíaca" a (...) esa "creencia", en el entendido de que resulta imposible fijarla y definirla en un sentido estricto porque no excluiría nada, ni siquiera a sus opuestos.: Based on The Gay Science’s last book, in this paper I proceed, first, to set the features of the new Nietzschean understanding of belief as an active determining opposed to the claim of truth traditionally understood as correction or adjustment of representation. That is to say, belief understood, in an important even though paradoxical sense, as counterbelief. Second, I aim to characterize although roughly what could be considered as the specifically Nietzschean belief, constitutive of his philosophical production’s core meaning. We should call that "belief" the "Dionysian faith", in the understanding that fixing and defining it would be strictly speaking rather impossible, since it does not exclude anything, not even its opposites.

El artículo presenta un análisis comparativo de los últimos parágrafos de la Vida de Pirrón de Diógenes Laercio y de un capítulo del Adversus ethicos de Sexto Empírico. Los resultados de este análisis harán plausible la hipótesis de una fuente común, reproducida parcialmente en DL, pero elaborada y refinada en Sexto. En ambos textos son centrales las nociones de fin y de elección. Se presentan las diferencias entre ambos textos entorno a la primera, y las tensiones internas comunes que implica (...) el tratamiento de la segunda. The article provides a comparative analysis of the final paragraphs of Diogenes Laertius' Life of Pyrrho and a chapter from the Adversus ethicos by Sextus Empiricus. The results of the analysis make plausible the hypothesis regarding a common source, partially reproduced in DL, but elaborated on and refined in Sextus. The notions of end and choice are central in both texts. The paper presents the differences between the texts regarding the former and the common internal tensions entailed by treatment of the latter. (shrink)

Este trabajo representa una búsqueda del rasgo negativo esencial que habría venido caracterizando a la actividad filosófica en nuestra cultura: una lucha sin tregua contra la estupidez humana, entendida en sentido profundo como fracaso de la inteligencia, un fracaso que sería sinónimo y compendio de maldad y de fealdad. Al mismo tiempo se atreve a pronosticar un futuro optimista para la filosofía, a pesar de todas las apariencias, por lo menos en la medida en que al estúpido le resultaría imposible (...) ser humanamente feliz.

The objective of this article is to analyze the production of the subject Woman by reviewing some practices, discourses, and technologies promoted by the state, the church, and elites. It is important to emphasize that in most research about women or femininity, female subjectivity appears tightly linked to sexual difference. However, in this work I want to show that the notion of Woman is co-determined by race and class. The experience characteristic of such representation was possible only for a small (...) group of white and bourgeois women. Others—Indian, black, and mestiza “women”—could hardly account for a social experience comparable to the Western narrative about woman. Nevertheless, processes of homogenization allow these others to be classified and disciplined according to the gender norm, yet without altering the prejudices and inequalities produced by the prevailing racist and classist system, which implies the production of other female subjectivities, of other “women.”.

We report a scanning tunnelling microscopy investigation of the emission of dislocations around nanoindentations in the form of dislocation arrangements previously called hillocks , consisting of two pairs of Shockley partial dislocations, each encompassing a stacking fault. The spatial arrangement and size distribution of hillocks around the nanoindentation traces are studied. We show that standard dislocation theory for an isotropic continuum can be used to describe the stability of the hillocks, their size and spatial distribution and the broadening of the (...) corresponding extended dislocations near the surface. A model is proposed in which hillocks originate from the split into dislocations partials of primary perfect dislocation loops punched into the crystal by the scanning tunnelling microscope tip. This model implies the operation of a novel dislocation mechanism involving long-range transport of matter across the surface. (shrink)

La obtención de alimentos sanos y seguros requiere de técnicas de conservación inocuas para el consumidor y para el me­dio ambiente, entre las que se destaca la bioconservación. A su ca­tálogo de compuestos naturales o microorganismos, utilizados de forma habitual, la bioconservación ha incorporado recientemente los bacteriófagos y las proteínas fágicas con actividad lítica. La utilización de fagos y endolisinas en el biocontrol ofrece importantes ventajas frente a otros sistemas de conserva­ción tradicionales. Entre dichas ventajas destacan su inocuidad, especificidad y (...) versatilidad. Por otra parte, la acuciante necesidad de reducir el uso de antibióticos en la cadena alimentaria ha impul­sado la investigación basada en estos antimicrobianos con el fin de aplicarlos en producción primaria. Sin embargo, y a pesar de la gran eficacia ya demostrada en múltiples sectores, la falta de legislación de la Unión Europea sobre el uso de bacteriófa­gos junto con la necesidad de ser aceptados por los consumidores, son factores que están afectando negativamente a su implantación como bioconservantes. En este contexto, este artículo recoge los últimos resultados relacionados con este tipo de antimicrobianos en la industria agro-alimentaria, y resume los puntos clave para entender las posibilidades reales de su aplicación ante los nuevos requisitos asociados con una producción sostenible tanto desde una perspectiva económica como ambiental.

En la educación médica cubana se ha diseñado un currículo para el cumplimiento de su encargo social donde se inserta la enseñanza del inglés. Actualmente constituye una prioridad trabajar en la búsqueda de estrategias que favorezcan el perfeccionamiento idiomático de los egresados, en este sentido se desarrolló una investigación en la Filial de Ciencias Médicas de Colón con el objetivo de desarrollar la expresión oral en el inglés con fines específicos en el tercer año de la carrera de Medicina. Se (...) emplearon métodos como el análisis de documentos, la observación participante, y los registros anecdóticos. El sistema de actividades aplicado favorece la negociación de significados, toma de riesgos, mayor precisión al expresar ideas, así como el acercamiento del uso del idioma en situaciones reales con lo cual se logra mayor motivación, objetividad del aprendizaje e independencia, al emplear las habilidades lingüísticas para su desempeño profesional. In Cuban medical education, a curriculum in which English is integrated, is designed to fulfill a social mission. Presently, it is a priority to identify strategies that support the idiomatic improvement of graduates. To this end, an investigation was developed in the University of Medical Sciences of Matanzas at Colon Campus with the objective of developing speaking in English for Specific Purposes in the third-year of the medical program of study. Methods such as document analysis, participant observation, and review of anecdotal records were used. The resulting system of activities favors the negotiation of meaning, risk-taking, improved precision to express ideas and the expanded use of English language in real situations. This results in greater motivation, learning objectivity and independence to use language skills for their professional performance. (shrink)

Based on experience in marriage counseling and contributions made by philosophy of phenomenology and psychology, we have carried out an in-depth analysis of the forgiveness process in the marriage relationship. Philosophy of phenomenology allows to define the conceptual framework of the marriage relationship and its essential features, which gives the therapist a reference to guide the therapeutical process. The description of the process is enriched with contributions of Psychology and particularly Systemic Family Theories. We have identified a number of steps (...) in the forgiveness process, which can be summarized as the passing from the initial pain, through the recovery of dignity and hope, up to the final consciousness of having reached forgiveness, where the intrapersonal process in the offended spouse is imbricated with the interpersonal relationship with the partner in marriage. This interdisciplinary perspective, bringing together clinical practice, philosophy of phenomenology, and psychology, has proven particularly fruitful: it has allowed us to identify when forgiveness becomes a case of regeneration and strengthening of the bonds of marriage, or on the contrary, the cases in which the problems, together with situations of imbalance or relational pathology progress to a chronic state. Apart from this, we have reflected upon the practical application of this theoretical approach in a therapeutic context with couples that need to pass through the forgiveness process, paying special attention to the risks they may encounter. Finally, we suggest possibilities for further investigations along these interdisciplinary lines of study. (shrink)

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

En The paradox of Addition and its dissolution (1969), Mario Bunge presenta algunos argumentos para mostrar que la Regla de Adición puede ocasionar paradojas o problemas semánticos. Posteriormente, Margáin (1972) y Robles (1976) mostraron que las afirmaciones de Bunge son insostenibles, al menos desde el punto de vista de la lógica clásica. Aunque estamos de acuerdo con las críticas de Margáin y Robles, no estamos de acuerdo en el diagnóstico del origen del problema y tampoco con la manera en la (...) que se proponen solucionarlo. En esta medida, en este texto mostraremos cómo la Regla de Adición sí trae problemas semánticos que pueden ser planteados desde diferentes perspectivas contemporáneas, como la extensionalidad del condicional, los principios proscriptivos y la validez conexiva.

Animal vocalizations convey important information about the emitter, including sex, age, biological quality, and emotional state. Early on, Darwin proposed that sex differences in auditory signals and vocalizations were driven by sexual selection mechanisms. In humans, studies on the association between male voice attributes and physical formidability have thus far reported mixed results. Hence, with a view to furthering our understanding of the role of human voice in advertising physical formidability, we sought to identify acoustic attributes of male voices associated (...) with physical formidability proxies. Mean fundamental frequency, formant dispersion, formant position, and vocal tract length data from a sample of 101 male voices was analyzed for potential associations with height, weight, and maximal handgrip strength. F0 correlated negatively with HGS; Pf showed negative correlations with HGS, height and weight, whereas VTL positively correlated with HGS, height and weight. All zero-order correlations remained significant after controlling for false discovery rate with the Benjamini–Hochberg method. After controlling for height and weight—and controlling for FDR—the correlation between F0 and HGS remained significant. In addition, to evaluate the ability of human male voices to advertise physical formidability to potential mates, 151 heterosexual female participants rated the voices of the 10 strongest and the 10 weakest males from the original sample for perceived physical strength, and given that physical strength is a desirable attribute in male partners, perceived attractiveness. Generalized linear mixed model analyses—which allow for generalization of inferences to other samples of both raters and targets—failed to support a significant association of perceived strength or attractiveness from voices alone and actual physical strength. These results add to the growing body of work on the role of human voices in conveying relevant biological information. (shrink)

Se realizó una investigación cualitativa, entre octubre de 2015 y junio de 2016, en la Casa de Abuelos No. 2 de Santa Clara con el objetivo de caracterizar la representación social de la sexualidad de los adultos mayores. Se seleccionó una muestra de 24 adultos mayores. Se utilizaron técnicas como: observación, entrevista, debate grupal, asociación de palabras, de cuestionamiento del núcleo central y la triangulación de datos. Como resultados se determinó que en la representación de la sexualidad se observó un (...) campo estructurado y un contenido que se aleja de su significado. Se concluyó que la representación social de la sexualidad de los adultos mayores se identificó con las relaciones sexuales, con el acto sexual. Las informaciones que poseen carecen de calidad y denotan un carácter prejuiciado y estereotipado. Manifestaron actitudes de rechazo hacia la sexualidad lo que se explicó por: el desconocimiento, la inadecuada relación entre sexualidad y reproducción, la existencia de prejuicios sociales y asociar el envejecimiento con la enfermedad. With the aim of characterizing the social representation of sexuality in senior citizens, a qualitative research was carried out from October 2015 to June 2016 in Grandparents House No. 2 in Santa Clara City. A sample of 24 people was selected. Methods such as observation, interview, group debate, words association, central core questioning technique and data triangulation were used. It was determined that in the representation of sexuality there is a structured field and a content that goes away from its meaning. Social representation of sexuality in senior citizens was identified with sexual relationships and with sexual intercourse. They lack quality information and show a prejudiced and stereotyped character. They expressed rejection attitudes towards sexuality which were based on: ignorance, inadequate connection between sexuality and reproduction, existence of social prejudice and association of aging with disease.

Organ shortage constitutes an unsolved problem for every country that offers transplantation as a therapeutic option. Besides the largely implemented donation model and the eventually implemented market model, a theorized automatic organ procurement model has raised a rich debate in the legal, medical and bioethical community, since it could show a higher potential to solve organ shortage. In this paper, we study the main arguments for and against this model. We show how, in the light of empirical data extracted from (...) countries with a universal health care system, its implementation could lead to a positive impact on organ procurement rates. Three factors are envisioned as fundamental in the comprehension and a possible regulation of the automatic organ procurement model: the lack of recognition of the conscientious objection, the preservation of the right to choose end of life conditions, and the need to avoid incentives for families or healthcare professionals.

More and more studies and research have found a positive relationship between the participation of young people in altruistic activities and helping others, but it is interesting to discover a relationship of that personal and vocational satisfaction in the preparation and training in a profession as important to society as teaching. For students who begin university studies related to teaching, their psychological well-being and motivation towards this activity are very relevant aspects to consider. The access to and attainment of a (...) University Degree with a great vocational character, such as that of Pre-School Teacher or Primary Education Teacher, can benefit the students who will be in charge. These future educational professionals will have adequate motivation and maintain a psychological well-being that, in short, will favour their personal balance and will impact their future students. This research aims to analyse the degree of psychological well-being and its relationship with the motivation towards starting the teaching career. A sample of 233 students and students aged between 17 or 19 years of age who are beginning university studies at the School of Education of Ciudad Real was selected. All participants are enrolled in the first year of the Degree in Pre-school and Primary Education. The relationship between the psychological well-being of the students and their motivation towards attaining a professional teaching career was analysed. Other variables such as age or sex were also taken into account. A quantitative study was carried out and the Ryff Psychological Welfare Scale and the Intrinsic Motivation Questionnaire (IMI) were used. Once the results were analysed, it was observed that there is a positive correlation between the perception of psychological well-being that the participants have and their motivation towards the beginning of university studies, whose professional focus is mainly direct teaching with the students of the early stages of Pre-school and Primary Education. There are also some significant differences, considering the age and sex of the participants. The vocational character of university preparation for the teaching profession may determine that students who begin their Degree studies have an important motivation towards the performance of their professional future.

In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric (...) analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future. (shrink)
