A través de los aspectos paratextuales en tres textos latinoamericanos: Último round, de Julio Cortázar, La historia de mis dientes, de Valeria Luiselli y Tatuaje del Centro de Cultura Digital, esta investigación aborda el concepto de libro-objeto y su transformación desde el boom latinoamericano hasta el libro electrónico del siglo XXI. Gracias a la comparación entre las obras se ilustra cómo el texto y su formato refleja la multiplicidad de discursos característica del siglo XX y XXI, se analiza cómo la (...) intermedialidad, es decir la hibridez entre soportes, tipografías, idiomas y discursos, es reflejo de realidades simultáneas que permiten crear textos a múltiples voces. Al requerir de la participación del lector, estas obras permiten la discusión sobre la figura del autor como una estructura policéfala, sobre todo llegado el siglo XXI cuando la literatura electrónica es producida tanto por software, ilustradores, animadores, y el propio escritor. La investigación concluye con una reflexión en torno a la relación entre el texto y el libro, a través de ella podemos deconstruir las ideas preconcebidas de literatura y género. A pesar de que el formato del objeto-libro electrónico parece novedoso, en realidad es otra manifestación -acorde a los tiempos que corren- de los juegos literarios y los formatos que soportan un texto, por lo que se espera que este estudio sea útil a los interesados en las formas actuales y la evolución que la literatura ha sufrido para integrarse al medio en el que se desarrolla.

Los cineastas han definido unos estereotipos femeninos y maternos en aquellos filmes dedicados a la violencia política irlandesa desde 1926. La fuerte retórica nacionalista de estas películas ha mantenido casi inmutables los atributos de las madres como mímesis de la patria. Al iniciarse los Procesos de Paz en 1996 y tras la firma de los Acuerdos de Viernes Santo de 1998, directores y guionistas han enriquecido sus narrativas para mostrar la presencia de las mujeres en la esfera pública. La producción (...) de estas películas, realizada en tres países diferentes, Irlanda, Gran Bretaña y Estados Unidos, ha determinado los modelos de la maternidad en consonancia con el imaginario colectivo de los diferentes públicos, influyendo a su vez en la construcción del relato sobre el conflicto armado y las mujeres.

El siglo XX fue una centuria de grandes descubrimientos científicos y desarrollos tecnológicos en todas las áreas, pero en particular en lo relativo a la conquista del espacio. Durante años, la bioética fue pensada en estrecha relación con la ética médica y el ámbito de problemas específicamente humanos, pero en los últimos tiempos su sentido se ha ido ampliando. El presente trabajo busca relacionar esta preocupación por una ciencia de la supervivencia con la existencia de la llamada basura espacial o (...) chatarra espacial que orbita la Tierra, y que en un tiempo no conocido afectará pequeñas o grandes áreas de nuestro planeta. La basura espacial se ha convertido en una preocupación cada vez mayor, especialmente en los últimos años, puesto que las colisiones a velocidades orbitales pueden producir aún más basura espacial en el proceso llamado síndrome de Kessler, o cascada de ablación, lo que perjudicaría el funcionamiento de los satélites, afectaría las misiones espaciales o pondría en riesgo la vida de los astronautas. También es probable que dicha basura se precipite sobre la Tierra, con efectos no claramente evaluados sobre la población humana. Aunque el problema suele aparecer tanto en textos científicos como en obras de ciencia-ficción, no ha sido considerado con la seriedad exigida para un riesgo real y no alejado de la vida cotidiana.

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

Since 2001, filmmakers have reflected in their works the consequences of terrorism on those women who, directly or indirectly, have been victims of political violence. This article analyzes the cinematographic treatment given to these victims in four countries - Ireland, Germany, Italy and Spain - after the terrorist groups laid down their arms. The objective is to know the differences and similarities of the stereotypes proposed in the films. Those women who were silenced during the hardest years of the armed (...) struggle will now be defined with characteristics that serve as a universal model to understand the role of women in society after conflicts.

We expose some representations and practices related to the natural environment among Nahua peasants in a village located at the western boundary of Puebla and Guerrero states, in Mexico. Information was obtained by individual interviews and focal groups' work, following an open guide with ecological items considered as rooted in Mesoamerican cultures. The use of some local, vegetal resources, and the local perception of changes, mainly in the water availability, is documented. Survival strategies involve ancestral representations and material products, and (...) entail a high grade of pragmatism. “Natural environment” is framed in a local culture that involves relational and sacred dimensions, usually omitted in other approaches. Hence, for the Temalac peasants, there is no dissection, at an operative level, between “natural facts” and personal or social ones, being these often considered as determinant for the quality and accessibility of resources and weather conditions. We discuss the challenge for these elements posed by a growing migration rate and an increasing external influence. (shrink)

Feature selection is a widely studied technique whose goal is to reduce the dimensionality of the problem by removing irrelevant features. It has multiple benefits, such as improved efficacy, efficiency and interpretability of almost any type of machine learning model. Feature selection techniques may be divided into three main categories, depending on the process used to remove the features known as Filter, Wrapper and Embedded. Embedded methods are usually the preferred feature selection method that efficiently obtains a selection of the (...) most relevant features of the model. However, not all models support an embedded feature selection that forces the use of a different method, reducing the efficiency and reliability of the selection. Neural networks are an example of a model that does not support embedded feature selection. As neural networks have shown to provide remarkable results in multiple scenarios such as classification and regression, sometimes in an ensemble with a model that includes an embedded feature selection, we attempt to embed a feature selection process with a general-purpose methodology. In this work, we propose a novel general-purpose layer for neural networks that removes the influence of irrelevant features. The Feature-Aware Drop Layer is included at the top of the neural network and trained during the backpropagation process without any additional parameters. Our methodology is tested with 17 datasets for classification and regression tasks, including data from different fields such as Health, Economic and Environment, among others. The results show remarkable improvements compared to three different feature selection approaches, with reliable, efficient and effective results. (shrink)

BackgroundPsychiatric neurosurgery is experiencing a revival. Beside deep brain stimulation, several ablative neurosurgical procedures are currently in use. Each approach has a different profile of advantages and disadvantages. However, many psychiatrists, ethicists, and laypeople are sceptical about psychiatric neurosurgery.MethodsWe identify the main concerns against psychiatric neurosurgery, and discuss the extent to which they are justified and how they might be overcome. We review the evidence for the effectiveness, efficacy and safety of each approach, and discuss how this could be improved. (...) We analyse whether and, if so, how randomised controlled trials can be used in the different approaches, and what alternatives are available if conducting RCTs is impossible for practical or ethical reasons. Specifically, we analyse the problem of failed RCTs after promising open-label studies.ResultsThe main concerns are: reservations based on historical psychosurgery, concerns about personality changes, concerns regarding localised interventions, and scepticism due to the lack of scientific evidence. Given the need for effective therapies for treatment-refractory psychiatric disorders and preliminary evidence for the effectiveness of psychiatric neurosurgery, further research is warranted and necessary. Since psychiatric neurosurgery has the potential to modify personality traits, it should be held to the highest ethical and scientific standards.ConclusionsPsychiatric neurosurgery procedures with preliminary evidence for efficacy and an acceptable risk–benefit profile include DBS and micro- or radiosurgical anterior capsulotomy for intractable obsessive–compulsive disorder. These methods may be considered for individual treatment attempts, but multi-centre RCTs are necessary to provide reliable evidence. (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)

From the most prominent thinkers in Latin American philosophy, literature, politics, and social science comes a challenge to conventional theories of globalization.

Los derechos de la infancia son de formulación reciente, y hasta el siglo XX no surgen los primeros intentos de reconocerlos y regularlos. Además de revisar los textos jurídicos que formulan y protegen esos derechos a nivel mundial, este estudio promueve una lectura filosófica de los derechos de la infancia y del papel de las familias con respecto a esos derechos. La ética del cuidado proporciona un marco de reflexión muy oportuno para plantear la responsabilidad ética que las familias, y (...) la sociedad en general, tienen hacia los niños y niñas, que son los miembros más vulnerables de la sociedad y los que padecen con mayor crudeza las consecuencias de la pobreza, la migración o los desastres naturales. Este estudio lleva a cabo una revisión crítica sobre los derechos de la infancia y los principales intentos de reconocer y garantizar jurídicamente esos derechos a nivel internacional. Explora también la situación actual de la infancia a nivel mundial, enfatizando las consecuencias negativas de la pandemia de COVID-19 en ese sector vulnerable de la población. Por último, se adopta la perspectiva de la ética del cuidado para analizar las responsabilidades de las familias y el papel de las instituciones y de la sociedad en general hacia la protección de la infancia.

El pensamiento de María Zambrano emerge, en la distancia histórica, bajo la imagen, siempre sugerente, de una Antígona contemporánea. Como ella asiste al conflicto trágico de una Guerra Civil; como ella apura el cáliz del sufrimiento y la soledad para hacer emerger una conducta ética y moral que sirva de Guía a sus contemporáneos, en un momento de crisis y confusión. Todas las grandes nociones del pensamiento zambraniano (sueño, confesión, guía, alba y aurora) se dan cita en esta máscara, pero (...) será el personaje galdoniano de la Nina de Misericordia, como aspiración pura nunca lograda, el verdadero motor que revela la personalidad de María Zambrano, tal como la vemos florecer en sus obras finales, Aurora, Claros del bosque y, sobre todo, Los bienaventurados.

Esta mesa-redonda foi organizada a partir do encontro de seus autores em um simpósio sobre historiografia no 55º Congresso Internacional de Americanistas, que ocorreu em julho de 2015, em San Salvador. O simpósio em questão foi o de número 69, Historia de la historiografía latinoamericana: nuevas miradas y debates contemporáneos. Os trabalhos aqui apresentados pelo guatemalteco Jose Edgardo Cal Montoya, “La historia como profesión”: el aporte de Ernesto Chinchilla Aguilar a la historiografía guatemalteca y centroamericana e o paraguaio Herib Caballero (...) Campos, Entre Clío y Astra: La Biblioteca Paraguaya del Centro de Estudiantes de Derecho, envolveram estudos historiográficos de temáticas nacionais específicas, respectivamente sobre a figura de um intelectual, e de uma instituição responsável pela divulgação de uma produção do conhecimento. Já os artigos de Coralia Gutiérrez Álvarez, Una introducción a la epistemología desde el sur: por una reflexión situada e Felix Raúl Martínez Cleves, La historiografía en movimiento. Una aproximación a las historias de ciudades en Colombia buscaram um outro viés na discussão historiográfica. Algo que diz respeito não somente a uma análise crítica, denominador comum a todos os quatro artigos, senão um diálogo com a teoria que implicou deslocar de uma zona de conforto a própria historiografia colombiana, para o caso dos estudos da história das cidades feito por Felix Martínez, e mais amplamente o conjunto das denominadas Ciências Sociais, como a discussão proposta por Coralia Gutiérrez. A mim coube analisar os quatro artigos, bem como buscar apontar possíveis diálogos entre os mesmos. Uma menor propensão de minha parte a debates teóricos, e uma maior facilidade a estudos com base mais histórica, como nos trabalhos de Jose Cal e Herib Caballero, se refletiram na maior extensão que dei no trato destes últimos; nada mais do que isso. E de antemão quero agradecer a Felix Martínez, cujos esclarecimentos possibilitaram divisar melhor uma ponte entre todos os trabalhos. (shrink)

Understanding human beings and their distinctive rational and volitional capacities requires a clear account of such things as reasons, desires, emotions, and motives, and how they combine to produce and explain human behaviour. Maria Alvarez presents a fresh and incisive study of these concepts, centred on reasons and their role in human agency.

How do nuclear technologies become commonplace? How have the borders between the exceptional and the banal been drawn and redrawn over the last 70 years in order to make nuclear energy part of everyday life? This special issue analyzes the role of fun and display, broadly construed, in shaping the cultural representation and the material circulation (or non-circulation) of nuclear technologies. Four case studies, covering the United States, Great Britain, Portugal, Spain, and Ukraine from the 1950s to the 2000s, explore (...) how specific forms of public display and playful practices of cultural production were used as means to banalize (or de-banalize) nuclear energy. This introduction addresses the main theoretical and historiographical signposts of the special issue and outlines the different ways in which the articles explore them. (shrink)

Pain perception arises from a complex interaction between a nociceptive stimulus and different emotional and cognitive factors, which appear to be mediated by both automatic and controlled systems. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, emotional influences on pain under unaware conditions are much less known. The aim of the present study was to investigate the modulation of pain perception by unconscious emotional pictures through an emotional masking paradigm. Two kinds of both somatosensory (...) (painful and non-painful) and emotional stimulation (negative and neutral pictures) were employed. Fifty pain-free participants were asked to rate the perception of pain they were feeling in response to laser-induced somatosensory stimuli as faster as they can. Data from pain intensity and reaction times were measured. Statistical analyses revealed a significant effect for the interaction between pain and emotional stimulation, but surprisingly this relationship was opposite to expected. In particular, lower pain intensity scores and longer reaction times were found in response to negative images being strengthened this effect for painful stimulation. Present findings suggest a clear pain perception modulation by unconscious emotional contexts. Attentional capture mechanisms triggered by unaware negative stimulation could explain this phenomenon leading to a withdrawal of processing resources from pain. (shrink)

Este trabajo parte de la pregunta por la posibilidad de deducir un planteamiento estrictamente político de los análisis ontológicos de la modernidad llevados a cabo por Martin Heidegger. Con este fin, se examina su interpretación del fenómeno griego de la pólis, así como la distinción que en ella se establece entre esta forma de comunidad y el Estado moderno, fundado para Heidegger en la esencia metafísica de la modernidad. Para clarificar esta cuestión se atiende a la proclamación de valores que (...) Heidegger observa en los diferentes modos de organización estatal que aparecen en la época de la consumación técnica de la metafísica. En conexión con ello, se estudia su visión del nihilismo y se ofrece finalmente una hipótesis sobre la forma de Estado que resultaría coherente con la renuncia a los valores que, a su juicio, exige la manifestación del ente en la modernidad como objeto por entero producible.

Es una tesis admitida y común la que sostiene que Descartes introdujo la forma moderna del método y del quehacer filosófico, caracterizados ambos por su desconexión del terreno de la espiritualidad, del cuidado de sí, de la ascesis y de toda una forma de vida. Se considera que Foucault compartía esa tesis, lo que en su momento criticaría Pierre Hadot. En el presente trabajo tratamos de mostrar que la forma en que Descartes elaboró su método y su propuesta no se (...) ajusta a aquella tesis recibida. En él se mantiene la relación antigua entre filosofía y espiritualidad, método y paideía. Una vez mostrado esto, apuntamos finalmente cómo en él, sin embargo, se abrió la vía para que se diera la ruptura que él no practicó. (shrink)
