Literatura y teatro: una experiencia de formación y de elaboración de materiales para el estudio

It is summarized an experience of teaching improvement belonging to the initiative of the University of Córdoba and carried out between 1999-2002, paying special attention to the last year, in which the resulting materials were computerized. As well as the initiation of a work group into the documentation skills. The project was focused on the creation of images to assist the teaching and learning of Spanish literature, and particulary the 17th-18th drama. The materials have been useful as a support in class, and after being printed and computerized they are thought for the individual use of students in their learning process.Se extracta una mejora docente acogida de la iniciativa de la Universidad de Córdoba y desarrollada entre 1999 y 2002, con especial atención al último año, con la adaptación a soportes electrónicos y virtuales de los materiales resultantes. Además de la iniciación de un grupo de trabajo en las técnicas de documentación, el proyecto se orientó a la elaboración de imágenes para el apoyo de la enseñanza y apendizaje de la Literatura española, y en particular del Teatro de los siglos XVII y XVIII. Los materiales de carácter instrumental han servido para el apoyo de las clases y su tratamiento y plasmación en soportes impresos e informáticos se han pensado para el uso individual del estudiante en su proceso de aprendizaje

A bibliometric study of the research area of videogames using Dimensions.ai database

Videogames are a very interesting area of research for fields as diverse as computer science, health, psychology or even social sciences. Every year a growing number of articles are published in different topics inside this field, so it is very convenient to study the different bibliometric data in order to consolidate the research efforts. Thus, the aim of this work is to conduct a study on the distribution of articles related to videogames in the different fields of research, as well as to measure their interest over time, to identify the sources, countries and authors with the highest scientific production. In order to carry out this analysis, the information system Dimensions.ai has been considered, since it covers a large number of documents and allows for easy downloading and analysis of datasets. According to the study, three countries are the most prolific in this area: USA, Canada and UK. The obtained results also indicate that the fields with the highest number of publications are Information and Computer Sciences, Medical and Health Sciences, and Psychology and Cognitive Sciences, in this order. With regard to the impact of the publications, differences between the number of citations, and the number of Altmetric Attention Score, have been found

Evaluación de la actividad física en población juvenil de Mallorca

En esta investigación se pretende lograr un objetivo principal, que es la evaluación a nivel descriptivo de la actividad física en la población juvenil de la isla de Mallorca. Para ello, se siguen una serie de pasos que se inician con la extracción de una muestra de 945 jóvenes mallorquines entre los 16 y 27 años, mediante un muestreo estratégico de municipios, y, dentro de cada municipio, un muestreo estratificado de sujetos por cuotas y rutas. En la recogida de datos se empleó un cuestionario diseñado para cubrir el objetivo marcado, instrumento que consta de cuatro partes: la primera de ellas evalúa la práctica deportiva actual; la segunda y tercera parte hacen referencia a las razones de esta práctica, tanto razones de inicio como de mantenimiento; y finalmente, la cuarta parte hace un recorrido sobre el uso y satisfacción de las instalaciones deportivas. Entre los resultados más importantes destacan las diferencias existentes en cuanto a práctica de deporte en función del género.This investigation pretends to achieve a main aim, that is the evaluation of the physical activity in a descriptive level of the young population of Mallorca's island (Spain). So as to accomplish that we extract a sample including 945 young people from Mallorca between 16 and 27 years old. They were selected by strategic sampling of towns and inside every one another sampling of subjects chosen by fees and routes. To collect data we use a questionnaire designed in order to achieve the aim already said. This tool consist of four parts: the first one evaluates the current sporting practice; the second an third ones are related to the main reasons to practice sport (the reasons to begin and the reasons to continue); and finally the fourth one is about the use and satisfaction of the sports installations. To sum up, we can say that one of the most important results are the differences between boys and girls in the fact of doing sport

A generalized smith predictor for unstable time-delay SISO systems

[EN] In this work, a generalization of the Smith Predictor (SP) is proposed to control linear time-invariant (LTI) time-delay single-input single-output (SISO) systems. Similarly to the SP, the combination of any stabilizing output-feedback controller for the delay-free system with the proposed predictor leads to a stabilizing controller for the delayed system. Furthermore, the tracking performance and the steady-state disturbance rejection capabilities of the equivalent delay-free loop are preserved. In order to place this contribution in context, some modifications of the SP are revisited and recast under the same structure. The features of the proposed scheme are illustrated through simulations, showing a comparison with respect to the corresponding delay-free loop, which is here considered to be the ideal scenario. In order to emphasize the feasibility of this approach, a successful experimental implementation in a laboratory platform is also reported.This work was partially supported by the projects PROMETEOII/2013/004, Conselleria d'Educacio, Generalitat Valenciana; TIN2014-56158-C4-4-P-AR, Ministerio de Economia y Competitividad; and the FPI-UPV 2014 PhD Grant, Universitat Politecnica de Valencia, Spain.Sanz Díaz, R.; García Gil, PJ.; Albertos Pérez, P.

The culture of conflict in family business

Conflict is part of the human condition. Therefore, it is neither negative nor positive, but rather a natural phenomena. The negative connotations traditionally attributed to conflict are at odds with current theories that explain the use of the term as an engine of change and generator of competitive advantage. The fact that family business is defined by two different systems, the family and the business, can lead to the emergence of many conflicts, but it can also help a business be successful if it can correctly differentiate between the two. To this end, both parties, the family and the business, must keep their own interests at arm's length and focus on common interests and goals.

Number conserving particle-hole RPA for superfluid nuclei

Automatic identification of physical activity intensity and modality from the fusion of accelerometry and heart rate data

Background: Physical activity (PA) is essential to prevent and to treat a variety of chronic diseases. The automated detection and quantification of PA over time empowers lifestyle interventions, facilitating reliable exercise tracking and data-driven counseling. Methods: We propose and compare various combinations of machine learning (ML) schemes for the automatic classification of PA from multi-modal data, simultaneously captured by a biaxial accelerometer and a heart rate (HR) monitor. Intensity levels (low/moderate/vigorous) were recognized, as well as for vigorous exercise, its modality (sustained aerobic/resistance/mixed). In total, 178.63 h of data about PA intensity (65.55% low/18.96% moderate/15.49% vigorous) and 17.00 h about modality were collected in two experiments: one in free-living conditions, another in a fitness center under controlled protocols. The structure used for automatic classification comprised: a) definition of 42 time-domain signal features, b) dimensionality reduction, c) data clustering, and d) temporal filtering to exploit time redundancy by means of a Hidden Markov Model (HMM). Four dimensionality reduction techniques and four clustering algorithms were studied. In order to cope with class imbalance in the dataset, a custom performance metric was defined to aggregate recognition accuracy, precision and recall. Results: The best scheme, which comprised a projection through Linear Discriminant Analysis (LDA) and k-means clustering, was evaluated in leave-one-subject-out cross-validation; notably outperforming the standard industry procedures for PA intensity classification: score 84.65%, versus up to 63.60%. Errors tended to be brief and to appear around transients. Conclusions: The application of ML techniques for pattern identification and temporal filtering allowed to merge accelerometry and HR data in a solid manner, and achieved markedly better recognition performances than the standard methods for PA intensity estimation

Elementos constructivos, materiales, sistemas estructurales y recursos ornamentales propios de la arquitectura tradicional canaria

La Arquitectura Tradicional Canaria es producto de aportaciones exteriores de varios estilos constructivos, adaptados al clima y al uso de materiales del entorno. En ella predominan la austeridad, sencillez y la funcionalidad, siendo tres las vertientes fundamentales de arquitectura: la militar, la religiosa y la civil (Urbana y Rural). El sistema constructivo se desarrolla con muros de carga, sobre encepados de piedra, constituidos por mampuestos, unidos y revestidos con morteros de barro o cal, forjados de vigas de madera, con tirantes que absorben los esfuerzos horizontales, y techos de cubierta inclinada con estructura de madera y tejas sobre un entablonado cuajado, recibidas con mortero de barro. Se hace necesario realizar intervenciones en los edificios, ante el requisito de reintegrar al edificio de unas disfunciones, que se agrupan principalmente en cuatro causas: obsolencia, uso, siniestralidad, y degradación. La conservación, restauración, consolidación, rehabilitación y remodelación, son las herramientas que la ley de Patrimonio Histórico de Canarias pone de manifiesto para la protección y conservación del edificio con garantías de cumplimiento de la funcionalidad del mismo.Tópico 1: Aspectos teóricos, históricos, legales, económicos y tecnológicos de la restauración y conservación de bienes patrimoniales
