This article provides an introduction to the themed section ‘Anarchism and the national question—historical, theoretical and contemporary perspectives.’ We discuss first the long and often overlooked engagement of anarchists with the colonial and national liberation question, particularly—but not exclusively—in the heyday of the movement (from the second half of the 19th to the first decades of the 20th century). We discuss in particular the overlaps and tensions between anarchists and republicans (those who favoured republics as opposed to monarchies) and anti-colonial (...) nationalists (anti-colonialists who defended the right of national self-determination). Then we proceed to discuss the potential for a dialogue between anarchist and nationalism studies based on three interventions. First, to problematise the narrative that conflates nations with state-building processes. Second, to better grasp the emergence of alternatives to the nation–state as a historical construct. Third, to complicate narratives that associate in an unproblematic fashion internationalism and classless society. Finally, the introduction highlights the four questions which lie at the core of the themed section and discuss briefly how the papers relate to these. (shrink)

Hace dos décadas se incorporó a la agenda pública el interés por el embarazo adolescente en tanto expresión de la pobreza y la vulnerabilidad de la población femenina juvenil. Este artículo presenta un análisis integral del problema a través de cuatro entradas: 1) un breve panorama de las políticas públicas adoptadas en estas dos décadas y diagnóstico que les dio origen; 2) profundiza en la magnitud del embarazo de mujeres menores de 20 años (a partir de datos sobre embarazadas y (...) no del número de hijos nacidos vivos de madres) y compara tres registros: 1995-1996 -Censo de alumnas embarazadas en el sistema escolar, MINEDUC-; 2006 y 2009 -CASEN, registro de menores de 20 años embarazadas-; 3) Profundiza en las vulnerabilidades de estas jóvenes a partir de testimonios sobre el sentido y ejercicio de la sexualidad en la experiencia juvenil; 4) Plantea que la condición de madre adolescente conlleva la vulnerabilidad a mayores condiciones de pobreza, y de exclusión a derechos y beneficios otorgados por el sistema educacional, fundamentándolo en el análisis de las bases de datos de la CASEN 2006 y 2009.

This article studies the differences between traditional financial intermediaries (commercial banks, savings banks and cooperative banks) and ethical banks based on property rights, in which the owner decides the ideology, principles, standards and objectives of the organisation. In ethical banking, affinity centres on positive social and ethical values. The article consequendy focuses on an index proposed both to differentiate ethical banks from other types of banks, and also to pinpoint the differences between the various ethical banks themselves.This is the Radical (...) Affinity Index (RAI), which groups banks together in terms of their stance on ethical commitment, concentrating on ethical ideology and principles (information transparency, placement of assets, guarantees and participation) and using a sample of 114 European banks. The evidence shows that transparency of information and placement of assets are factors that differentiate ethical banks from other financial intermediaries.Guarantees and participation are characteristics specific to ethical banks; these variables, however, do not offer clear evidence to our analysis.

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the most effective activity (...) for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (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)

Este artículo explora desde una perspectiva filosófica la forma como la rostricidad está asociada al deseo y producción de subjetividad. De ahí que el campo de interés se centre en cómo dichas categorías tensionan la constitución subjetiva de los sujetos, a tal punto que inciden en la proyección de su propio trayecto biográfico. Esto a partir de algunos planteamientos teóricos acuñados por filósofos como Foucault, Deleuze y Guattari, con respecto al papel del rostro como productor de significado cultural en la (...) gestión de la economía del deseo. Con miras a ambientar el texto, se tomará como recurso a Catarino, personaje de la novela Cien años de soledad, de Gabriel García Márquez. (shrink)

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.

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)

The focus is on the meaning of ὑπόϑεσις in Irenaeus of Lyons’ Adversus haereses. Our case is to argue that two different elements converge in ὑπόϑεσις or its translations in the Latin version of AH. The first stems from the Greek literary field, in which ὑπόϑεσις means the “subject” or “plot” of a dramatic or poetic composition. The second is related to the philosophical meaning of ὑπόϑεσις as “that which is placed under” or “foundation”. On the one hand, Irenaeus uses (...) ὑπόϑεσις theologically to express the plot of the historia salutis, so that the term can be understood as teaching or doctrine. On the other hand, this ὑπόϑεσις is at the same time a regula, the normative foundation of all the elements that take part in God’s economy of salvation. (shrink)

By simply watching news channels, visiting the internet, even watching diverse films, my observations led me to conclude that in today’s globalized world, different forms of subjective violence – or a kind of violence that has a clear and identifiable agent – are what commonly occupies our attention. However, it is crucial to note that in every form subjective violence, there is an objective background that invisibly sustains and overdetermines it. This objective frame, often imperceptible, contains a systemic and more (...) perilous violence, for it is, in fact, a violence that prolongs and generates the very subjective violence that we are fighting and responding against. Accordingly, I would argue that a reinvention of how we view a truly ethical act should necessitate itself in today’s globalized world. My claim is that the challenge for a truly globalized ethics is that it is not enough to simply respond to these different forms of subjective violence. Instead, what is more gripping to consider is to shamelessly question the objective violence upon which these different forms of subjective violence are inherent, reacting against, and being sustained in the first place – i.e. the inherent violence produced by the predominance of global capitalism.

La sobre-tecnificación inhumana ha promovido una visión reduc- cionista que afecta la forma en que se ejerce la medicina, dañando gravemente la relación médico-paciente. La carencia de formación en competencias humanísticas determina una visión utilitarista y sociobiologista. La deficiencia en la comprensión con respecto a las emociones individuales y ajenas es determinante en las habilidades sociales que, como médicos, debemos promover en las próximas generaciones, de modo que logremos recentrar la atención médica y científica en una visión antropocentrista. La Inteligencia (...) Emocional (IE) es definida como la habilidad para percibir e identificar las emociones ajenas y propias, para discriminar entre ellas y utilizar dicha información para guiar el pensamiento, actuando en consecuencia. Es necesario estructurar la educación médica de las competencias humanísticas en beneficio del ejercicio profesional, fundado en habilidades de comunicación que reflejen una visión integral del ser humano. Se llevó a cabo una revisión de 83 artículos, con la finalidad de identificar la relación existente entre la Inteligencia Emocional y la relación médicop-paciente, presentando un panorama integral sobre la relevancia que la enseñanza de dichas competencias tiene en la educación médica del siglo XXI.

The fast–slow paradigm of life history focuses on how individuals grow, mate, and reproduce at different paces. This paradigm can contribute substantially to the field of personality and individual differences provided that it is more strictly based on evolutionary biology than it has been so far. Our study tested the existence of a fast–slow continuum underlying indicators of reproductive effort—offspring output, age at first reproduction, number and stability of sexual partners—in 1,043 outpatients with healthy to severely disordered personalities. Two axes (...) emerged reflecting a double-track pathway to fast strategy, based on restricted and unrestricted sociosexual strategies. When rotated, the fast–slow and sociosexuality axes turned out to be independent. Contrary to expectations, neither somatic effort—investment in status, material resources, social capital, and maintenance/survival—was aligned with reproductive effort, nor a clear tradeoff between current and future reproduction was evident. Finally, we examined the association of LH axes with seven high-order personality pathology traits: negative emotionality, impulsivity, antagonism, persistence-compulsivity, subordination, and psychoticism. Persistent and disinhibited subjects appeared as fast-restricted and fast-unrestricted strategists, respectively, whereas asocial subjects were slow strategists. Associations of LH traits with each other and with personality are far more complex than usually assumed in evolutionary psychology. (shrink)

In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)

RESUMEN Se exploran las relaciones entre hegemonía y filosofía de la praxis en A. Gramsci. Se examina la influencia de la filosofía hegeliana sobre estas nociones en los Cuadernos de la cárcel. Asimismo, se estudia la crítica a estas nociones a la luz del feminismo de la diferencia y del debate sobre hegemonía, universalidad y contingencia iniciado por E. Laclau, J. Butler y S. Žižek. Se concluye que concebir la hegemonía desde la perspectiva de la filosofía de la praxis significa (...) que la acción político-intelectual, según Gramsci, no solo implica la formación de una hegemonía alternativa, sino una crítica políticamente operante a la pretensión de universalidad del discurso hegemónico a partir de la exposición de su contingencia histórica. ABSTRACT The paper explores the relations between hegemony and the philosophy of praxis in A. Gramsci, and examines the influence of Hegelian philosophy on these notions as set forth in the Prison Notebooks. Likewise, it studies the critique of these notions from the perspective of difference feminism and of the debate over hegemony, universality, and contingency initiated by E. Laclau, J. Butler, and S. Žižek. The conclusion is that conceiving hegemony from the perspective of the philosophy of praxis means that, according to Gramsci, political-intellectual action implies not only the formation of an alternative hegemony, but also a politically operative critique of the claim to universality of hegemonic discourse, on the basis of the unveiling of its historical contingency.

ObjectivePreviously Mindfulness-Based Swinging Technique 's immediate efficacy for overcoming psychological concerns has recently received empirical support, yet its longer-term efficacy needed to be evaluated among women with breast cancer. The objective of this study was to assess and report the efficacy of MBST intervention among breast cancer patients for hopelessness, anxiety, depression, self-efficacy, oxygen intensity, and heart rate-beats per minute at an 8-week period.MethodThe State-Trait Anxiety Inventory, The Emotion Thermometer, Hospital Anxiety and Depression Scale, Self-Efficacy for Managing Chronic Disease, and (...) Beck's Hopelessness Scale were used for assessing the intervention's outcome; 149 BC patients were randomly assigned into two groups. The participants in the control group received Cognitive Behavioural Therapy -Cognitive-Disputation for 20 min, and intervention group received MBST intervention. No additional psychological interventions were given between week-1 and week-8.ResultOutcomes of the 8-week post-treatment follow-up exhibited significantly higher improvements in all evaluated-measurements for CG, and some for IG with large effect size in the following: anxiety and depression levels. It increased self-efficacy for managing disease and hopefulness, and saturation levels measured by pulse-meter/oximeter.ConclusionsBoth CBT-CD and MBST have been found to be efficacious interventions to shorten the psychotherapy duration for reducing clinical anxiety and hopelessness as well as increase self-efficacy for BC women. This may have a distinct clinical importance for supporting BC patient's adherence-to-treatment since CBT-CD could be an alternative technique to MBST as a brief intervention. In future studies, the effectiveness of MBST through adapting to virtual reality and other online delivery methods should be examined. (shrink)

El artículo lleva a cabo un breve recorrido a través del cuestionamiento filosófico de la noción de causalidad.

The presence of premises expressing comparison is a problem for the Aristotelian theory of the dialectical method, first because there is no general theory of comparison in the Organon and secondly because along with propositions on the opposition and inflexion of the terms, comparative statements seem to fall outside the explicit description which Aristotle gives of possible premises. The purpose of this paper is to offer a synthetic theory of comparisons according to Aristotle’s Topics, in an attempt both to supply (...) the aforementioned absence and to highlight the importance of the second problem. There are three main types of premises on the more, the less and the similar: some comparing the degree of possession of a predicate, others comparing the plausibility of a predication and finally, others expressing an analogy. Once expounded the very marked differences that occur between these three classes of propositions, the paper analyses the various kinds of argumentation based on comparative premises and offers a formalization of its logical laws. The complexity of this theory and the volume of topoi involved in the comparisons show the magnitude of a problem that has not been sufficiently studied. (shrink)

RESUMEN El presente estudio está dirigido a establecer coincidencias entre el pensamiento de José Martí y de Carlos Marx en el terreno filosófico. Ambos representan los más altos exponentes del saber filosófico y humanista de la cultura europea y latinoamericana del siglo XIX, respectivamente, con un alcance genuinamente universal. No fue objetivo en modo alguno convertir a Martí en marxista, del mismo modo que sería absurdo afiliar a Marx a las ideas y las concepciones martianas. Sin embargo, no es (...) posible dejar de subrayar la profundidad del ideario martiano en el terreno filosófico, político, social y económico y sus aproximaciones a las concepciones marxistas o al socialismo científico. ABSTRACT The present study is directed to establish coincidences between the thought of José Martí and Carlos Marx in the philosophical area. Both are represented by the highest exponents of the philosophical and humanist knowledge of the European and Latin-American culture of the 19th century, respectively, with an authentically universal scope. It was not objective in any way to turn Martí into Marxist, in the same way that it would be absurd to affiliate Marx to the ideas and the Martí´s conceptions. Nevertheless, it is not possible to stop underlining the depth of the Martí´s ideology in the philosophical, political, social and economic area and his approaches to the Marxist conceptions or to the scientific socialism.

Background: Serious games have shown positive results in increasing motivation, adherence to treatment and strengthening the therapeutic alliance in multiple psychiatric disorders. In particular, patients with impulse control disorders and other disorders in which the patient suffers from inhibitory control deficits have been shown to benefit from serious games.Aim: The aim of this study was to describe the characteristics and to evaluate the usability of a new serious videogame, e-Estesia. This serious videogame was designed to improve emotion regulation in patients (...) with gambling disorder. Preliminary results from a pilot sample are also reported.Method: A pilot sample of 26 patients undergoing treatment for GD was recruited. Participants used e-Estesia on a tablet, which was connected to a thoracic band that sent heart rate and heart rate variability data to the videogame platform in order to provide biofeedback. The System Usability Scale was completed by patients to determine the usability of e-Estesia.Results and Discussion: e-Estesia performed comparatively well for all the explored groups. Around 84.6% of the patients endorsed that it was easy to use. Female patients with GD presented higher HRV during the use of the serious videogame compared to men. (shrink)

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

Audiovisual communication is greatly contributing to the emerging research field of affective computing. The use of audiovisual stimuli within immersive virtual reality environments is providing very intense emotional reactions, which provoke spontaneous physical and physiological changes that can be assimilated into real responses. In order to ensure high-quality recognition, the artificial intelligence system must be trained with adequate data sets, including not only those gathered by smart sensors but also the tags related to the elicited emotion. Currently, there are very (...) few techniques available for the labeling of emotions. Among them, the Self-Assessment Manikin devised by Lang is one of the most popular. This study shows experimentally that the graphic proposal for the original SAM labelling system, as devised by Lang, is not neutral to gender and contains gender biases in its design and representation. Therefore, a new graphic design has been proposed and tested according to the guidelines of expert judges. The results of the experiment show an overall improvement in the labeling of emotions in the pleasure–arousal–dominance affective space, particularly, for women. This research proves the relevance of applying the gender perspective in the validation of tools used throughout the years. (shrink)

Self-determination theory considers motivation as a multidimensional phenomenon, with different levels of intensity, purposes, intentions, wills and autonomies. It distinguishes between intrinsic motivation, extrinsic motivation and amotivation. In this paper, we are going to focus on extrinsic motivation, which is related to those tasks that the subject performs without having a purpose in themselves, and which is composed of identified regulation, introjected regulation and external regulation. The aim of this research is to analyse the relationship between them and emotional intelligence (...) in 165 students with university degrees related to Physical Activity and Sport Sciences. The main findings of this work lie mainly in the demonstration of the fact that emotional intelligence is a predictor of identified regulation, introjected regulation and external regulation.

The rapid increase of industry-sponsored clinical research towards developing countries has led to potentially complex ethical issues to assess. There is scarce evidence about the perception of these participants about the ethical compliance, security, and protection. We sought to evaluate and contrast the awareness and perception of participants and non-participants of industry-sponsored research trials on ethical, safety, and protection topics. A Cases-control survey conducted at twelve research sites in México. Previous and current participants of ISRT as well as non-participants with (...) one of four chronic diseases, were asked to complete the survey which focused on ethical compliance and protection issues of ISRT, and the perception of participating in a trial. A total of 604 cases and 604 controls were surveyed. Cases significantly answered that ethics committees are aware of what is happening in studies, and that medical care of industry-sponsored research trials is better than their usual medical care. The same proportion of cases and controls thought patients must receive economical reimbursement for participating in a research study. The informed consent of the pharmaceutical clinical trial was fully read by 90.4% of the cases. Most cases were satisfied or very satisfied with their overall study participation. Previous and current participants of industry-sponsored research trials have a more positive attitude towards ethics committees, the quality of medical care of the research trials, and the main purpose of economical reimbursements, when compared to non-participants.

Data were collected through a questionnaire (scale) on the social skills of primary school students linked to the adequate skills when losing, the adequate skills when winning, and (...) the adequate skills during the game. Study results revealed that analyzed behaviors vary, depending on the moment of the game, being it more frequently during the development of the game than when losing or winning. (shrink)

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)

Este texto trabaja a partir de la poesía de José Manuel Arango. Dada la formación filosófica del poeta, se buscó en su obra una reflexión con respecto a las preguntas fundamentales al ser humano y que la filosofía ha intentado responder desde la antigüedad: qué idea del hombre, del mundo y de la existencia hay en su poesía, de tal forma que pudiera establecerse un puente entre la filosofía y la literatura; y derivada de esta última, pero igualmente importante, (...) se indagó por la reflexión estética que allí subyace, su concepción del arte, del artista y particularmente de la poesía. Y ambas preguntas tendieron, a su vez, a un fin común: encontrar la posibilidad de verdad que hay en su obra. (shrink)

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

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)

Diabetes has been associated with affective disorders which complicate the management of the disease. Emotional intelligence, or the ability to perceive, facilitate, understand, and regulate emotions, has shown to be a protective factor of emotional disorders in general population. The main objective of this study was to systematically review the role of the EI construct in Type 1 and Type 2 diabetics and to observe how EI is related to biological and psychological variables. Comprehensive searches were conducted in PubMed, Scopus, (...) PsycInfo, and Cochrane without time limitations, for studies examining the link between diabetes and EI. A total of 12 eligible studies were selected according to the inclusion criteria. We divided the results into four sections: EI and hemoglobin glycosylated, EI training effects, differences in EI between persons with diabetes and without diabetes, and EI and psychological adjustment and well-being. The results showed negative correlations between EI and HbA1c, positive effects of EI training on quality of life, anxiety, and glycemic control, no differences in EI between people with diabetes and healthy individuals, and, finally, negative correlations between EI and different psychological variables such as diabetes-related anxiety and distress, and positive correlations with quality of life, well-being, and marital satisfaction. This systematic review offers a starting point for a theoretical and practical understanding of the role played by EI in the management of diabetes and reveals that EI is a promising protective factor for biological and psychological variables in this population.

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and (...) its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes. (shrink)

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.

Aims: Attentional bias, alcohol craving, and anxiety have important implications in the development and maintenance of alcohol use disorder. The current study aims to test the effectiveness of a Virtual Reality Cue-Exposure Therapy to reduce levels of alcohol craving and anxiety and prompt changes in AB toward alcohol content.Method: A 49-year-old male participated in this study, diagnosed with severe AUD, who also used tobacco and illicit substances on an occasional basis and who made several failed attempts to cease substance misuse. (...) The protocol consisted of six VR-CET booster sessions and two assessment sessions over the course of 5 weeks. The VR-CET program consisted of booster therapy sessions based on virtual reality exposure to preferred alcohol-related cues and contexts. The initial and final assessment sessions were focused on exploring AB, alcohol craving, and anxiety using paper-and-pencil instruments and the eye-tracking and VR technologies at different time points.Results: Pre and post assessment sessions indicated falls on the scores of all instruments assessing alcohol craving, anxiety, and AB.Conclusions: This case report, part of a larger project, demonstrates the effectiveness of the VR-CET booster sessions in AUD. In the post-treatment measurements, a variety of instruments showed a change in the AB pattern and an improvement in craving and anxiety responses. As a result of the systematic desensitization, virtual exposure gradually reduced the responses to significant alcohol-related cues and contexts. The implications for AB, anxiety and craving are discussed. (shrink)
