eXtended hybridizable discontinuous Galerkin for incompressible flow problems with unfitted meshes and interfaces

The eXtended hybridizable discontinuous Galerkin (X-HDG) method is developed for the solution of Stokes problems with void or material interfaces. X-HDG is a novel method that combines the hybridizable discontinuous Galerkin (HDG) method with an eXtended finite element strategy, resulting in a high-order, unfitted, superconvergent method, with an explicit definition of the interface geometry by means of a level-set function. For elements not cut by the interface, the standard HDG formulation is applied, whereas a modified weak form for the local problem is proposed for cut elements. Heaviside enrichment is considered on cut faces and in cut elements in the case of bimaterial problems. Two-dimensional numerical examples demonstrate that the applicability, accuracy, and superconvergence properties of HDG are inherited in X-HDG, with the freedom of computational meshes that do not fit the interfacesPeer ReviewedPostprint (author's final draft

Eficacia de las intervenciones con niños y adolescentes con Trastorno por Déficit de Atención con Hiperactividad (TDAH)

This study presents the results of a diachronic literature review of publications about approaches to ADHD treatment, in order to determine the number and efficacy of treatment approaches during the last 25 years. Results derived from this literature review of three temporal periods (1986-1992; 1994-2000; 2001-2011), show that studies were mainly focused on pharmacological treatment. Possible explanations of this trend are argued, emphasising the need to promote multimodal and contextual intervention

Los géneros periodísticos en la didáctica del periodismo en España. Un recorrido histórico

This article shows the influence that journalistic genres had on the first organisation of communication studies in Spain as well as the role they remain to play in the teaching of journalism. A review is done starting from the origins of the didactics of genres, continuing with the role of genres in the beginning of regulated studies of journalism, and finalising with an analysis of their place in present education programmes which reveals that practical and theoretical knowledge of the genres are still a main objective in the training of future journalists in Spain.Este artículo tiene como objetivo mostrar la influencia que tuvieron los géneros periodísticos en las primeras estructuraciones de los estudios de comunicación en España y el lugar que hoy siguen ocupando en la enseñanza universitaria del periodismo. Para ello se hace un recorrido que parte de los orígenes de la didáctica de los géneros, continúa con el papel de los géneros en el establecimiento de la enseñanza reglada del periodismo y finaliza con un análisis de su situación en los planes de estudio actuales que revela que el conocimiento teórico y práctico de los géneros sigue siendo un objetivo primordial en la formación de futuros periodistas en España

Efficacy of Attention Deficit Hyperactivity Disorder treatments in children and adolescents

En este estudio presentamos un análisis diacrónico sobre la investigación en el tratamiento del TDAH infantil y adolescente, para determinar el número y la eficacia de las modalidades de intervención empleadas durante los últimos 25 años. Los resultados derivados de revisiones bibliográficas de tres períodos temporales distintos (1986-1992; 1994-2000; 2001-2011), muestran que la mayoría de ellos se ha centrado en analizar la eficacia del tratamiento farmacológico. Se concluye con explicaciones de esta tendencia, enfatizando la importancia de implementar intervenciones multimodales y contextualizadas.This study presents the results of a diachronic literature review of publications about approaches to ADHD treatment, in order to determine the number and efficacy of treatment approaches during the last 25 years.

Effects of the behavioral activation in the life quality and emotional state for lung cancer patients

Objetivo: Desde un análisis contextual-funcional de los problemas/limitaciones del paciente oncológico, se valora el efecto en la calidad de vida y estado emocional de una intervención centrada en la Activación Conductual con enfermos de cáncer de pulmón durante el tratamiento oncológico.Método: 90 pacientes de reciente diagnóstico fueron asignados aleatoriamente a una condición experimental (G.E.: N=50) de 4 sesiones individuales orientadas a restablecer actividades relevantes, eliminar conductas de enfermedad y modificar el patrón de evitación experiencial; y a una condición control (G.C.: N=40) que ocupó el mismo número de sesiones en la evaluación de la calidad de vida sin ofrecer asesoramiento o tratamiento psicológico. Todos los participantes completaron, en cada sesión y en seguimiento trimestral, las escalas QLQ-C30, HAD, IK, EG y SP. Se empleó un diseño de medidas parcialmente repetidas. La evolución y tendencia de las variables se realizó mediante MLG y MLM. Resultados: Los participantes resultaron representativos de la población estudiada y no difirieron entre ellos en el pre-tratamiento. En ambos grupos se produjo una pérdida elevada de sujetos por hospitalización/fallecimiento. El G.E. mostró, a lo largo del tiempo, mejoría estadísticamente significativa (p<0,05) en todas las subescalas del QLQ-C30. En las subescalas HAD, se alcanzaron diferencias significativas entre grupos a favor del G.E (p<0,05). Los beneficios del G.E. se debilitaron en el seguimiento. El GC no experimentó cambios.Conclusiones: Se aportan evidencias del interés de los objetivos y procedimientos de Activación Conductual para mejorar, durante el tratamiento oncológico, la calidad de vida y estado emocional. Se señala la necesidad de indagar las características de los pacientes y/o de la intervención de las que depende su eficacia y eficiencia.Objective: Based on a functional-contextual analysis of the problems cancer patients have, the efficacy of Behavioral Activation Therapy for the prevention of emotional disorders and the promotion of life quality on lung cancer patients will be analyzed.Method: A total of 90 lung cancer patients were selected consecutively. Patients were randomly assigned to un experimental group (G.E.: N=50) where a specific protocol was designed to increase relevant activities and healthy behaviors, erasing disease behaviors previously learned and modifying the pattern of experiential avoidance; and a control group (G.C.: N=40) where life quality and psychosocial effects of both illness and treatment were assessed, without ever offering counseling or psychological treatment. Both conditions received a total of four individual one hour long treatment sessions in the hospital. Results were collected through standardized scales (IK, HADS, QLQ-C30, EG y SP) in each of the treatment sessions and during the three months follow-ups. The evolution and tendency of the variables was analyzed using MLG y MLM.Results: Participants, doe to their clinical and sociodemographic characteristics resulted a representative group of the population studied and did not differ between themselves in the pre-treatment. In both groups there was a loss of subjects produced by hospitalization / death. The comparison analysis inter and intra groups indicate that among participants, the G. E. showed, over time, statistically significant differences (p< 0.05) in all subscales of QLQ- C30 functioning. In the HAD subscales, significant differences between groups in favor of GE (p<0.05) were achieved. Improvements shown by the G.E. weakened during the follow-up.Conclusions: Behavioral Activation Therapy, during cancer treatment, improved life quality and emotional adjustment. The study indicates the need to investigate the characteristics of patients and/or intervention, as its effectiveness and efficiency depends on them

The Predictive power of the yield curve: evidence from Spain

Treball Final de Grau en Economia. Codi: EC1049. Curs acadèmic: 2022/2023The slope of the yield curve has been mentioned as a leading economic indicator of the economy’s path in the future. Thus, an inversion of the curve has been interpreted as a sign of a future recession. Over the last decades, empirical research has been made with the aim of finding a significant relationship between the yield curve and future economic activity. In this paper, we examine the predictive power of the yield curve in Spain. We consider a simple linear regression model which predicts the change in the industrial production using the yield spread as an explanatory variable. To study the stability of recession forecasts over time, we divided the full dataset in two sub-samples. Moreover, as the literature states that binary models are more stable at forecasting future economic activity, we consider a probit model to predict recessions using the yield curve. Results obtained in both models are not statistically significant at any conventional significance level

La glocalización de la comunicación

Actualmente se está haciendo cada vez más patente la existencia de una doble y simultánea tendencia de la comunicación en este nuevo siglo. Se trata del fenómeno de la globalización y de la atención a lo local, dos caras dentro del mismo mundo informativo. Lo local busca su espacio en la proximidad, mientras que la tecnología y la economía nos conducen a un escenario que cada vez tiene menos barreras. Ese proceso generalizado, con las paradojas y contradicciones que conlleva, viene siendo aquello a lo que algunos estudiosos de la comunicación hacen referencia a través del neologismo inglés glocalization.The existence of a double and simultaneous tendency in communication of this century is gettting increasingly obvious. This tendency consists of the phenomenon of globalization and the attention to the local environment, two sides of the world of information. The local environment is based on proximity, whereas technology and economy lead us to a global scene with less and less barriers. This general process, with all its contradictions, is what some scholars in communication now define as glocalization
