El aislamiento social y educativo vivido a nivel mundial por el SARS-CoV-2 imprimió retos a docentes, estudiantes y padres de familia, entre ellos, hacer uso de distintas herramientas informáticas y tecnológicas para realizar tareas y comunicarse. Las redes sociales sirvieron como punto de encuentro dando paso a comunidades virtuales de aprendizaje para quienes tenían dudas académicas, tecnológicas e incluso de apoyo emocional. Desde este escenario se plantea el presente estudio, analizando los participantes, interacciones y recursos compartidos que ayudaron para adquirir (...) ofortalecer las competencias digitales, a través de una etnografía virtual al grupo“Aprende en Casa 6° de Primaria”.

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)

Science fiction cinema proposal for Bioethic education Proposta do cinema de ficção científica para educar em Bioética Posthumanism state that technologies will eliminate aging, improve cognitive, physical and psychological skills and keep alive human minds by uploading them in machines as artificial intelligence. These beliefs, as constant features in science fiction films, could be useful to educate medical students in Bioethics. We propose some of these science fiction films related with technological changes of humans and the noxious consequences: Being turned (...) into a humanoid created by genetic engineering; a slave or a merchandize without rights; discrimination because of eugenesic genetic manipulation; and/or the creation of cyborgs of mass destruction. Also, the movies can show the reader issues of ethnic supremacy dilemmas, identity impersonate and ambition, impersonal intelligence and conscience and identity transpass after death. These films will help teachers to analyze with students the moral limits of science and technologies.

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.”.

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)

Feminist reflections on the sexual division of labour have given rise to a body of knowledge on the ethics of care from different disciplines, including philosophy, in which outstanding contributions to the topic have been formulated. This approach is applicable to the analysis of any phenomenon and particularly that of disasters. As various investigations have highlighted, the consequences on the population throughout all of a disaster’s phases (prevention, emergency, and reconstruction) require an analysis of differentiated vulnerabilities based on gender and (...) other identity categories, such as social class, ethnicity, age, disability, sexual identity, etc. The interrelation between all these variables gives rise to differentiated impacts that cannot be ignored in catastrophic contexts, where survival and sustaining life are at stake, so care becomes a central issue. Research on the topic has also identified that, along with the analysis of social vulnerability, we must consider the capacity for agency, both individual and collective, where care is once again of vital importance. Considering the gender approach and its multiple intersections is thus a fundamental theoretical-practical proposal for the study of disasters from philosophy, as it implies an unavoidable epistemic, ontological, and ethical reflection in the face of risk reduction.

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.

El objetivo principal de este manuscrito es presentar una nueva metodología de abordaje en la radicalización violenta usando como herramienta principal la metodología Scrum, la cual ha sido ampliamente usada en entornos de construcción de software. Se plantea una metodología de trabajo centrada en los destinatarios de la intervención: los adolescentes. Así, el método Scrum se ha mostrado, en multitud de ocasiones, muy eficaz como estrategia de aprendizaje colaborativo, habiéndose utilizado en entornos universitarios para el desarrollo de proyectos de gran (...) calidad durante breves periodos de tiempo. Abordando la carta de valores e interviniendo hacia valores incompatibles con la violencia se pretende lograr la disminución de la radicalización en este colectivo. (shrink)

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.

In this paper, the author offers an interpretation of the present day philosophical significance of the Scottish Enlightenment. After a broad review of the main characteristics of that movement and of the thought of major Scottish figures of the 18th century, the author proposes that contemporary debates concerning the nature and perspectives of progress in history could derive benefit from a critical reconsideration of some views put forth by the Scottish literati.

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.

We argue that the true nature of the renormalizability of Horava-Lifshitz gravity lies in the presence of higher order spatial derivatives and not in the anisotropic Lifshitz scaling of space and time. We discuss the possibility of constructing a higher order spatial derivatives model that has the same renormalization properties of Horava-Lifshitz gravity but that does not make use of the Lifshitz scaling. In addition, the state-of-the-art of the Lorentz symmetry restoration in Horava-Lifshitz-type theories of gravitation is reviewed.

Farmers are experts on their natural environment and are innate experimenters. However they do not know everything. Filling in gaps of missing farmer knowledge can help them improve their experiments. The authors designed and taught a course to Honduran farmers that effectively covered a number of key points on insect ecology and biology that farmers had not understood. After receiving the course many farmers did experiments to solve pest problems without synthetic pesticides.

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)

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. (shrink)
