Acoustical Behavior Of Churches: Mudejar-Gothic Churches

Christian churches have traditionally been considered to have very good acoustical behavior. This unfounded belief has led to important en-on in church rehabilitation works, especially when the church is to be used subsequently as an auditorium or theater; this is the case of many churches in Spain. Our research group has worked in acoustical analysis for more than ten years. We have participated in many cases of church rehabilitation and have had the opp&unity to achieve surprisingly good acwstical behavior in several. We deal with a very common type in southern Spain: Gothic-Mudejar churches, which have a small volume, a triple-nave layout, and wooden ceilings

Impact of climate change on wave energy resource: the case of Menorca (Spain)

The aim of this paper was to analyse how changes in wave patterns, due to the effect of climate change, can affect wave energy power and yield around Menorca (NW Mediterranean Sea). The present and future wave energy conditions were derived from recently developed high-resolution wave projections in the NW Mediterranean. These wave projections were forced by surface wind fields obtained, respectively, by 5 different combinations of global and regional circulation models (GCMs and RCMs) for the A1B scenario. The results showed that the projected future spatial and directional distributions of wave energy are very similar to those of the present conditions. The multi-model ensemble average illustrated a slight general decrease in the annual and seasonal wave power (except for summer). However, the inter-model variability is large since two models showed opposite trends to the other 3 in most cases. Such inter-model variability is lower(higher) for winter(autumn). Another result is the reduction of the temporal variability in the future, considering both the multi-model mean and each single model projection. Such a decrease is consistent with the future seasonal redistribution of energy throughout the year. This would entail an increase in the efficiency of wave energy converters deployed in this area due to the more regular temporal distribution of the energy.Peer ReviewedPostprint (author's final draft

El perfil del usuario de medios electrónicos en las 4 principales universidades de Bogotá

El trabajo de grado propuesto pretende dar a conocer algunas características que poseen las 4 principales Universidades de Bogotá como lo son la Javeriana, los Andes, la Sabana y el Rosario en cuanto a educación virtual, infraestructura para soportar la red de Internet, nivel de penetración y el uso que le dan a esta herramienta informática los estudiantes de cada plantel educativo. Por consiguiente, se analizará el entorno internacional, como evolucionó el tema desde sus orígenes en los Estados Unidos, su situación actual y los alcances de la herramienta en los países del mundo. Además se mostrará cómo se encuentran las tecnologías de la información y comunicación en algunas universidades del mundo, su aplicativo en los estudiantes y las ventajas que ofrecen para la educación actual y futura. Del mismo de las Universidades de Bogotá, su frecuencia de uso, actividades más comunes a través de esta herramienta, infraestructura para soportar esta herramienta, calidad del servicio, nivel de satisfacción y lo más importante quizás, es conocer si los estudiantes de las 4 principales modo se estudiará el nivel de penetración del Internet en los estudiantes universidades de Bogotá utilizan los medios electrónicos en las mismas instalaciones de las universidades. Para el desarrollo de esta investigación se realizaron encuestas a las directivas y personas encargados de temas afines en cada una de las universidades de estudio, de tal manera, que pudiéramos acercarnos a como se maneja el tema actualmente en las universidades de la capital colombiana, su desarrollo a lo largo del tiempo y su proyección hacia el futuro. Tras analizar los resultados de las entrevistas con directivas de los centros educativos, recopilar y analizar información relacionada al tema del Internet en las universidades, se llega a responder el principal objetivo de la investigación propuesta, el cual se fundamenta en conocer cuál es el perfil del usuario de medios electrónicos en las 4 principales universidades de Bogotá.The objective of this thesis is to inform the main characteristics for virtual education, infrastructure to support the internet network, level of penetration and the use that students give to this tool in each educative establishment in the four main universities in Bogota ( Javeriana, Andes, La Sabana, Rosario ), Therefore, the international surroundings will be analyzed, how it evolved since its origins in the United States, the actual situation and the reaches of the tool in the countries of the world. In addition it shows the technologies of the information and communication in some universities of the world, how the students use it and the advantages that offer for the present and future education. In the same way the level of penetration of the Internet in the students of the Universities of Bogota, how often they use it, common activities through this tool, infrastructure to support it, quality of the service, level of satisfaction. And perhaps the most important, aspect is to know if the students of the 4 main universities of Bogota use electronic means in the same facilities of the universities. In order to develop this investigation surveys were applied to the directives and people in charge of the subjects in each one of the universities of study, in order to approach the management of this area in the universities, their development throughout the time. After analyzing the results of the interviews with directives of the educative centers, compiling and analyzing the information related to the subject of the Internet in the universities, the main question is answered, which is based on knowing wich is the profile of the electronic means user in the 4 main universities of Bogota

How to use music scores in teaching and learning music?

The Version of Record of this manuscript has been published and is available in Cultura y Educación 2008 http://www.tandfonline.com/ http://dx.doi.org/10.1174/113564008783781503Este artículo estudia el uso que se hace de las partituras en la enseñanza de la interpretación musical. Tras esbozar la evolución histórica de las partituras como sistemas de notación o representación externa, proponemos que las partituras, en cuanto objetos representacionales cuya función es guiar una secuencia de acciones en la interpretación musical, pueden procesarse en tres niveles jerárquicamente organizados. De acuerdo con la propuesta de Postigo y Pozo (2000), en un primer nivel de procesamiento, se aprenderían sólo las notaciones presentes de modo explícito en la partitura, mientras que los niveles superiores requerirían procesar la estructura implícita en esas notaciones y establecer relaciones conceptuales entre esa partitura y los conocimientos musicales del aprendiz. A partir de estos niveles, el artículo muestra el uso que hacen de las partituras estudiantes de música que están formándose para ser profesores y termina reflexionando sobre las implicaciones que ello pudiera tener en sus futuras prácticas docentesThis article studies how scores are used on teaching and learning music performance. After outlining the historical evolution of music scores as notational system or external representation, we assume that scores are representational objects whose function is to guide a sequence of actions in music performance. Then we propose that scores may be processed according to three hierarchically ordered levels. According to Postigo and Pozo (2000), on a first level of processing only explicit notation in the score will be learnt, while on higher levels the implicit structure in these notations will be processed and the conceptual relationships between that score and the student’s previous musical knowledge will be established. Based on these levels, the paper shows how music students being trained as teachers use the score, and finishes by reflecting about the implications on their future practice as teachersEste artículo forma parte de la investigación Instrucción para el cambio representacional: de las teorías implícitas al aprendizaje de conocimientos en contextos educativos, financiada por el Plan Nacional I+D+, Ministerio de Educación y Ciencia, SEJ2006-15639-C02-01, cuya investigadora principal es María del Puy Pérez Echeverrí

A Focal-Point Solution for Bargaining Problems with Coalition Structure

In this paper we study the restriction, to the class of bargaining problems with coalition structure, of several values which have been proposed on the class of non-transferable utility games with coalition structure. We prove that all of them coincide with the solution independently studied in Chae and Heidhues (2004) and Vidal-Puga (2005a). Several axiomatic characterizations and two noncooperative mechanisms are proposed.coalition structure bargaining values
