Max Bill: variaciones sobre la búsqueda de la belleza

Max Bill es un artista lógico. Quince variaciones sobre el mismo tema 1938, podría ser el epítome de la lógica de Bill: la obra como resultado de la aplicación de leyes distintas sobre una estructura de orden. La gran diversidad formal de la obra de Max Bill –entre sus diseños de objetos, su tipografía, su pintura, su escultura o su arquitectura no parece haber líneas formales evidentes- se debe a que, para él, cada tarea es diferente y depende de medios y leyes propios. Una diversidad que podría ser erróneamente interpretada como un tipo de eclecticismo. Su conferencia en el Werkbund suizo de 1948 “belleza de la función, belleza como función”, se aleja del discurso funcionalista al proponer la belleza como una igual al resto de funciones. Cada obra ha de satisfacer la finalidad para la que ha sido construida y cumplir todas las funciones que en ella intervienen pero, además, ha de ser bella. La particularidad de Bill estriba en que, reconociéndose a sí mismo como un artista lógico, incluye la belleza como una más de las funciones a cumplir por cualquier objeto. Su famoso aforismo en relación a la configuración del entorno, desde la cuchara a la ciudad, incluiría la arquitectura en el ámbito de los objetos que han de cumplir esta nueva función. La búsqueda de la belleza será una constante en su obra. No una belleza generalizable y determinada a priori, sino una belleza entendida como predicado singular, individualizada para cada tarea. De este modo, podemos analizar, alternativamente, la belleza lógica de sus construcciones geométricas y la belleza simbólica de sus monumentos; la belleza del espacio sin fin en las superficies de una sola cara y la belleza prefabricada en sus más austeras realizaciones; la belleza elemental de sus esculturas y la belleza corriente con que sus arquitecturas se integran en la ciudad. Podemos plantearnos la posibilidad de una belleza de la estructura y entender simultáneamente la belleza cruda de su obra maestra, los edificios de la Escuela de Ulm. La búsqueda de la belleza nos ayudará a entender que, en la obra de Bill, la razón intuitiva -como modo de conocimiento- toma mayor importancia de la que parece. La forma como suma de todas las funciones en unidad armónica, será el resultado de un adecuado equilibrio entre razón lógica y razón intuitiva. ABSTRACT Max Bill is a logical artist. We could consider “Fitfteen variations on the same theme”, 1938, as the Bill’s logic epitome: the work as a result of the application of different tectonic laws on the order structure. The variety of the form in Bill’s work –his designed objects, his typography, his painting, his sculpture, or his architecture do not seem to have, between them, a direct line connecting the form- is due to the fact that, for him, each task is different and it depends on the own means and tectonic laws. A kind of diversity that could be misinterpreted like certain type of eclecticism. His lecture at the Suisse Werkbund (1948) “beauty from function and as function” is far from the functionalist speech, when proposing beauty as an equal to the rest of functions. In his own words, each work has to satisfy the purpose it was built for and fulfill all functions, and furthermore it has to be beautiful. Seeing himself as a logical artist, Bill however introduces beauty as one more of the functions that any object has to fulfill. His famous aphorism related to the environment management, from the spoon to the city, would include architecture as one more of the objects that have to satisfy this new function. The pursuit of beauty is a constant in his work. It won’t be a general beauty determined in advance, but a singular predicate, individualized for each task. That way, we can analyze, alternatively, the logical beauty of his geometric constructions and the symbolical beauty of his monuments; the beauty of the endless space in the single-sided surfaces and the prefabricated beauty in his most stricts constructions; the elemental beauty of his sculptures and the ordinary beauty with which some of his architectures are integrated in the city. We can also try the possibility of a beauty from the structure and understand, at the same time, the raw beauty of his architectural masterpiece, the buildings of the Ulm School of Design. The pursuit of beauty in Bill’s work will help us to understand that intuitive reason, as a way of knowledge, takes more importance than it seems. Form, as the harmonious expression of the sum of all functions, will be the result of an appropriate balance between logical and intuitive reason.

Propuesta de integración de agentes software inteligentes sobre JADE con entornos virtuales en Unity3D

La unión de distintos sistemas software constituye un elemento principal de las nuevas Tecnologías de la Información y la Comunicación. La integración de entornos virtuales tridimensionales con agentes software inteligentes es el objetivo que persigue este trabajo de investigación. Para llevar a cabo esta integración se parte de la creación de un agente virtual, un personaje que es controlado por una mente desarrollada siguiendo un enfoque basado en agentes software. Se busca así dotar al sistema de cierto nivel de inteligencia, tomando como referencia el funcionamiento del cerebro humano. Lo que se consigue es que el agente capte los estímulos del entorno, los procese y genere comportamientos, tanto reactivos como deliberativos, que son ejecutados por el personaje. Los resultados obtenidos resaltan el dinamismo del sistema, a la vez que animan a seguir investigando en este campo lleno de aplicaciones directas y reales sobre el mundo. En conclusión, esta investigación busca y consigue un nuevo paso en el progreso de las nuevas tecnologías mediante una integración real de distintos sistemas software. ---ABSTRACT---The union of different software systems is a major element of Information and Communications Technology. The aim of this research is the integration of 3D virtual environments and intelligent software agents. This integration is based on the development of a virtual agent, a character that is controlled by a mind developed following a software agent approach. It is sought to provide the system with some intelligence level, taking the human brain function as a reference point. The consequence is that the agent captures environmental stimuli, processes them and creates reactive and deliberative behaviours that can be executed by the avatar. The findings emphasize the dynamism of the system as well as they encourage to research more in this field that has a lot of direct and real-life applications on the world. In conclusion, this research seeks and takes a new step in the progress of new technologies through a real integration of different software systems.

La censura del tema deportivo en la prensa durante la posguerra española (1939-1945)

La presente tesis doctoral pretende arrojar nueva luz sobre la utilización de la prensa durante los primeros años del franquismo. En concreto, el objetivo ha sido estudiar la censura del tema deportivo dentro del sistema censorio de los primeros años de posguerra civil en España, una área no estudiada hasta hoy y que entendemos fundamental para entender el desarrollo del deporte durante el llamado primer franquismo. Para ello, se estudiaron de manera pormenorizada los actores principales y los pasos básicos del proceso de censura; los métodos utilizados, tanto materiales como personales, para hacer efectiva ésta; y, por último, sus manifestaciones reales en el ámbito de la información deportiva: qué se censuró, por parte de quién, de qué forma y por qué motivos. De este modo, pretendemos llenar una de las lagunas de investigación que aún quedan dentro del estudio de la censura de prensa durante el franquismo. La metodología utilizada es la técnica historiográfica. Basado en el análisis crítico y en la interpretación de fuentes primarias, dicho método trata de establecer marcos históricos de referencia a través del estudio pormenorizado de las circunstancias del pasado. Ello implica una estructura algo distinta a la de las tesis doctorales de otras áreas de estudio puesto que, exceptuando la introducción, toda la tesis es la exposición de los resultados de la investigación llevada a cabo. Se ha utilizado cuantiosa documentación de los archivos General de la Administracion (Alcalá de Henares) y Centrale dello Stato (Roma) no manejada anteriormente por ningún investigador. La prensa periódica de la época y la legislación que afecta a nuestro tema de estudio también han sido ampliamente investigadas, tanto en el contexto español como en el italiano. Nuestra investigación arroja los siguientes resultados. Efectivamente, existió censura de prensa en el tema deportivo en las siguientes temáticas fundamentales: cuestiones económicas, autoridades y jerarquías, uso del lenguaje y comportamiento de los deportistas. En la mayor parte de los casos, la censura se ejerce en la información deportiva por razones ajenas al propio deporte. No se puede afirmar que existan diferencias en el tratamiento general entre medios de la Prensa del Movimiento y otros de titularidad privada o eclesiástica, si bien la aplicación de la censura no fue homogénea sino arbitraria en muchos casos. El sistema de censura de prensa español del primer franquismo toma la mayoría de sus rasgos del modelo fascista italiano, aunque tiene alguna característica propia como la censura previa y el catolicismo imperante. ABSTRACT This doctoral thesis aims to shed light on the use of press during the first years of francoism. The particular objective was to study the censorship of the sport topic into the general system of censorship carried out after the Spanish Civil War. It is a subject comparatively understudied to date but a key aspect to understand the development of sport during the so called early francoism. To this end, an in-depth study was made on key actors, main steps of censorship process, human and material methods used to ensure its effectiveness, and the actual manifestations in sports information area: what was censored, by whom, how and why. This should ensure us to fill the historiographical gap within the research on Francoʼs press censorship. Methodology used was historiographic research. It is based on critical analysis and interpretation of primary sources and seeks to establish historical reference frameworks tracing back the past in detail. It determines a different doctoral thesis structure in some aspects. Except the introduction, the whole document is the report and explanation of the results of research. A large amount of unexplored documents from the Archivo General de la Administración (Alcalá de Henares, Spain) and the Archivio Centrale dello Stato (Rome, Italy) has been used. The press of the period and legislation about our topic have also been analysed in detail both in Spain and Italy. Our research states these results. We can affirm that press censorship actually existed on sports topic in these thematic priorities: economical issues, authorities and hierarchies, use of language and sportsmen behaviours. In most cases, the censorship of sports information is exercised for reasons unconnected to sport. It cannot be concluded that general differences were applied in press censorship between State-owned media and private or church media although its implementation was non-uniform and arbitrary in many cases. The system of press censorship in Spain during the early francoism is clearly inspired by fascist Italy system copying most of its features although Spain had a few specific characteristics like prior censorship and catholicism.

Multisensor data fusion for accurate modelling of mobile objects

In the last decade, multi-sensor data fusion has become a broadly demanded discipline to achieve advanced solutions that can be applied in many real world situations, either civil or military. In Defence,accurate detection of all target objects is fundamental to maintaining situational awareness, to locating threats in the battlefield and to identifying and protecting strategically own forces. Civil applications, such as traffic monitoring, have similar requirements in terms of object detection and reliable identification of incidents in order to ensure safety of road users. Thanks to the appropriate data fusion technique, we can give these systems the power to exploit automatically all relevant information from multiple sources to face for instance mission needs or assess daily supervision operations. This paper focuses on its application to active vehicle monitoring in a particular area of high density traffic, and how it is redirecting the research activities being carried out in the computer vision, signal processing and machine learning fields for improving the effectiveness of detection and tracking in ground surveillance scenarios in general. Specifically, our system proposes fusion of data at a feature level which is extracted from a video camera and a laser scanner. In addition, a stochastic-based tracking which introduces some particle filters into the model to deal with uncertainty due to occlusions and improve the previous detection output is presented in this paper. It has been shown that this computer vision tracker contributes to detect objects even under poor visual information. Finally, in the same way that humans are able to analyze both temporal and spatial relations among items in the scene to associate them a meaning, once the targets objects have been correctly detected and tracked, it is desired that machines can provide a trustworthy description of what is happening in the scene under surveillance. Accomplishing so ambitious task requires a machine learning-based hierarchic architecture able to extract and analyse behaviours at different abstraction levels. A real experimental testbed has been implemented for the evaluation of the proposed modular system. Such scenario is a closed circuit where real traffic situations can be simulated. First results have shown the strength of the proposed system.

Herramientas de gestión de compromiso para trabajadores del conocimiento

El objetivo de la línea de investigación seguida en esta tesis consiste en identificar palancas de gestión de las personas en las organizaciones que permitan mejorar su rendimiento mediante la gestión del compromiso de los profesionales de las organizaciones inmersas en la denominada sociedad del conocimiento. Para identificar dichas palancas se analizan algunos de los factores que, según la literatura científica, tienen como consecuencia cambios en la productividad, como son el compromiso organizacional y las conductas cívicas dentro de la organización. También, por su actualidad y relevancia en las prácticas de gestión de recursos humanos, se han analizado el impacto que tienen en estos factores en las prácticas empresariales que permiten conciliar vida profesional y personal el efecto del género en las distintas variables analizadas. Por todo lo anterior, en la investigación se analizan algunos de los factores de carácter psicosocial que promueven el compromiso en una organización, y se profundiza en dos conceptos: el análisis del compromiso de los profesionales con la organización para la que trabajan, y los comportamientos de ciudadanía organizativa que se exhiben en la organización por sus miembros. Para ello, se realiza un encuadramiento teórico de los siguientes conceptos: el compromiso como eje del trabajo; la ciudadanía organizativa como modelo cultural de la organización que promueve el compromiso; el rol de los líderes; los efectos de las políticas de conciliación; las diferencias de percepciones derivadas del género y un sistema de revisión de retributiva eficiente y coherente con el marco conceptual planteado. La metodología seleccionada para este trabajo ha sido el análisis en profundidad del caso de una empresa española, Red Eléctrica de España a través de tres pilares básicos: el primero consiste en el análisis exhaustivo de los datos obtenidos en las dos encuestas de clima social que dicha empresa realizó en el período 2006-2009; el segundo se centra en el desarrollo de un modelo matemático para el cálculo eficiente de recompensas salariales a través de un modelo de optimización; y el tercero es la consecuencia del conocimiento profundo que el autor tiene de la propia empresa, su cultura y funcionamiento, fruto de su experiencia profesional como directivo en el área de desarrollo de recursos humanos, función que desempeñó en la organización durante nueve años. En el análisis de este caso se ha investigado la influencia del género en el compromiso y la ciudadanía organizativa de los empleados de dicha organización, para identificar las diferencias de percepción que puedan ser explicadas por el género en una empresa muy masculina como es aquella. También, se ha incluido en este estudio de caso el análisis del efecto que presentan las medidas de conciliación en el compromiso de los empleados, por la relevancia que tiene este asunto en el panorama laboral español actual. Este análisis permite conocer hasta qué punto son o no motivadoras estas medidas en la organización analizada y, como consecuencia de ello, el tipo de gestión más oportuna de las mismas para conseguir no sólo los fines sociales que pretenden, garantizar que los empleados puedan compatibilizar sus exigencias laborales con una vida personal adecuada, sino también mejorar el clima, productividad y compromiso de éstos con la empresa. Para completar este análisis del caso, se han identificado de forma analítica los factores que mejor explican el clima de la organización y se ha concluido el papel central de la dirección que se concreta en la actuación de cada jefe, como motor del clima social en el equipo que dirige. Dado que la tesis pivota sobre el papel relevante que tiene la generación de una cultura de ciudadanía organizativa, se ha complementado el análisis con el desarrollo una herramienta de cálculo que facilita la determinación de los incrementos de la retribución fija de acuerdo con los principios de transparencia, equidad y justicia acordes con el modelo de empresa que promueve la virtud cívica de las personas empleadas en ella. Para ello se ha desarrollado un nuevo método de cálculo del incremento de retribución fija mediante un modelo analítico innovador y compacto de programación lineal entera mixta. Este modelo permite a las organizaciones realizar diseños de política retributiva de forma sencilla y rápida, a la vez que facilita la transparencia de las mismas en el proceso de gestión de la compensación. No se ha abordado el asunto de la determinación de la retribución variable, por ser un asunto relativamente menos complejo y profusamente tratado en la práctica directiva de las empresas. La primera de las conclusiones de la investigación realizada se refiere a los aspectos de la cultura organizativa que pueden identificarse como motores del compromiso. Se concluye que en el caso de estudio hay una fuerte relación mutua entre los rasgos que definen el compromiso emocional y los rasgos que determinan un comportamiento caracterizado como de ciudadanía organizativa. Se ha encontrado una correlación significativa y alta entre indicadores de compromiso y factores que recogen comportamientos de ciudadanía organizativa, correlación muy notable tanto para los factores de compromiso racional como para los de compromiso emocional. También se ha evidenciado que la correlación entre compromiso emocional y rasgos de comportamientos de ciudadanía organizacional es mayor que la que aparece entre compromiso racional y rasgos de comportamientos de ciudadanía organizacional. Desde el punto de vista de la práctica de gestión de recursos humanos, estas relaciones indican la conveniencia de promover una cultura organizacional basada en los principios de la ciudadanía organizativa para alcanzar altos niveles de compromiso emocional de los profesionales y mejorar la eficiencia organizativa. La segunda de las conclusiones se refiere al efecto de las políticas de conciliación en las organizaciones. Sobre este asunto se concluye que en el caso de estudio no puede considerarse que las medidas de conciliación tengan una fuerte relación con el compromiso emocional, y menos que puedan considerarse directamente una herramienta de generación de compromiso emocional. Sin embargo, sí que se detecta una cierta relación entre las percepciones de conciliación y de compromiso con la organización, y sobre todo, con el compromiso racional con la organización, que puede tener que ver con que para los empleados de la organización analizada, las medidas de conciliación son consideradas como una parte más de las condiciones laborales que ofrece la organización a los trabajadores. La tercera conclusión se refiere a la relación entre el género de los trabajadores y su nivel de compromiso y de ciudadanía organizativa. En el caso de estudio no se identifica una relación entre el género y el nivel de compromiso de los profesionales ni tampoco con la percepción de ciudadanía organizativa, variando la situación del período 2006 al período 2009. La cuarta conclusión se refiere al impacto que la actuación de los líderes (jefes) tiene en el clima social. En el caso de estudio, la actuación de los directivos y el nivel de compromiso que genera en los profesionales explica por sí sola más de un tercio de la varianza del clima organizativo, entendido como tal el que refleja el conjunto global de preguntas que constituyen la encuesta de clima del caso de estudio. Del análisis realizado se concluye que en el caso de estudio la percepción que los empleados tienen de sus jefes tiene un efecto relevante sobre el resto de percepciones de compromiso, ciudadanía organizativa y otros factores que conforman el clima social de la organización. La quinta y última conclusión supone la aportación de un modelo novedoso de cálculo de la recompensa económica coherente con un modelo de gestión empresarial mediante una cultura de ciudadanía organizativa. La solución que obtiene este modelo es el incremento salarial individual de cada profesional, que tiene en cuenta su rendimiento, posicionamiento salarial y encuadramiento profesional. Además de las restricciones presupuestarias, se consideran los principios de transparencia, equidad y justicia coherentes con el modelo conceptual planteado. La principal contribución de este trabajo es la formulación matemática de los criterios cualitativos que se emplean habitualmente en el proceso de revisión salarial. El método planteado supone una innovación que permite automatizar la metodología tradicional de gestión de incrementos salariales basados en matrices de incremento, así como evitar la aplicación de limitaciones en las valoraciones de desempeño derivadas de las restricciones presupuestarias que toda organización tiene. De esta manera se puede disponer de un mecanismo de revisión salarial que tiene en cuenta el desempeño de los profesionales, pero que permite la gestión “desacoplada” de la evaluación de rendimiento y la actualización de la retribución fija. ABSTRACT The aim of the research pursued in this thesis is to identify some human resources management levers in organizations to improve their performance through individual’s commitment management, focusing in organizations immersed in the so-called knowledge society. In order to find out these levers, the author analysed some of the psychosocial factors that promote engagement to the organizations and, according to the scientific literature, have effects in their productivity. These factors analysed are organisational commitment and citizenship behaviours. Additionally, the investigation also focuses on work-life balance policies and gender considerations, because of their relevance and topicality for the human resources’ policies. In the light of this, the investigation focuses on some of the psychosocial factors that promote organisational commitment, and delves into two concepts: the analysis of the commitment of professionals to the organization for which they work, and the organizational citizenship behaviours exhibited in the organization by its members. For this, a theoretical framework is performed for the following items: the professional’s commitment which is the pillar of this work; the organisational citizenship as a cultural model to promote that commitment; the role of the leaders; the effects of the work-life balance policies; the different perceptions of the professionals because of their gender; and an efficient salary review system, which is coherent with the conceptual framework set. The methodology selected for this work was the analysis in depth of the case of a Spanish company, Red Eléctrica de España, through three basic subjects: the first consists of a thorough analysis of the data obtained in the two work climate surveys made by this company in 2006 and 2009; the second focuses on the development of a mathematical model for calculating efficient salary reviews through an optimization model; and the third is the result of the author’s deep understanding of the company, its culture and its performance because of his professional experience as a manager in the area of human resource development, which was his role in the organization for nine years. The author investigated in the analysis of this case about the influence of gender on the employees’ organizational commitment and citizenship behaviours, in order to find out perception differences that can be explained by the highly masculine organisational culture such Red Eléctrica de España had during the studied period. Additionally, because of the importance of the work-life balance promotion in the Spanish labour scene, the case study analysis includes their effect in the employees’ commitment. This analysis allows to know motivating are these measures in the studied organization and, as a result, the most appropriate type of management thereof for social purposes, not only intended to ensure that employees can balance their work and personal demands, but also improving the work climate, the productivity and the organisational commitment. The investigation identifies the factors which best explain the work climate of the organization and concludes the central role of the leadership, embodied in the performance of every manager, to boost the work climate in their teams. Since this thesis pivots on the important role the generation of a culture of organizational citizenship has, the investigation has been complemented with the development of a analytic tool that facilitates the calculation of the salary review increments according to the principles of transparency, equity and justice in line with a work culture that promotes organisational citizenship behaviours. For this, this works develops a new method for calculating fixed salary increases through an innovative and compact mixed integer linear programming model. This model enables organizations to design compensation policies easily and quickly, and facilitates the transparency of the compensation management system. The method for determining variable remuneration has not been addressed because it is relatively less complex issue and widely discussed. The first conclusion of the conducted investigation concerns aspects of organizational culture that could be identified as commitment drivers. In the case study exists a strong and mutual relationship between the characteristics defining the emotional commitment and the organisational citizenship behaviours. The investigation has found out a meaningful and high correlation between indicators of commitment and the factors collecting organizational citizenship behaviour. This correlation with organisational citizenship is remarkable for both, rational and emotional, commitment. The correlation between organizational citizenship behaviours and emotional commitment and is greater than the one with rational commitment. From the practitioner point of view, these relationships show the importance of promoting an organizational culture based on the principles of organizational citizenship to achieve high levels of emotional engagement of professionals and improve organizational efficiency. The second conclusion relates to the effect of work-life balance policies in organizations. On this matter, the investigation concludes that for the case study, work-life balance measures do not have a strong relationship with the emotional commitment, and unless they can be usually considered as a tool to improve employees’ emotional commitment. However, a certain relationship between perceptions of work-life facilities and organisational commitment exists, especially with the rational commitment to the organization. This relationship appears because for employees of the analysed organization, work-life balance measures could be considered as a part of working conditions offered to them by the organization. The third conclusion concerns the relationship between the gender of workers and their level of commitment and organizational citizenship. In this case study, there is not any relationship between gender and the professional’s commitment level nor the perception of organizational citizenship; and the situation varies during the period studied. The fourth conclusion refers to the impact that the actions of the leaders have on the work climate. In the case study, the performance of management and the level of commitment generated, explains more than a third of the variance of work climate - understood as such reflecting the overall set of questions that constitute the work climate survey -. The analysis concludes that in the case study perception that employees have of their leaders has a significant effect on the rest of perceptions of commitment, organizational citizenship and other factors making the work climate of the organization. The fifth and last conclusion represents the contribution of a new model for calculating the salary increment, coherent with a corporate citizenship management culture. The solution obtained from this model consists of salary increases for each employee; these increases consider the employee’s professional performance, salary level relative to peers within the organization, and professional group. In addition to budget constraints, we modelled other elements typical of compensation systems, such as equity and justice. The major contribution of this work is the mathematical formulation of the criteria that are typically the basis for salary management. The compact formulation and the ease of obtaining the optimal solution facilitate its use in large companies that maintain very high levels of homogeneity across employees. Designing different strategies for specific groups within a company is also possible. A major benefit of this method is that it allows a company to independently manage its salary and assessment policies. Because obtaining salary-revision matrices without using the mathematical model we present in this paper is typically done iteratively by tuning previously defined matrices, managers commonly tune values for assessing employee performance to ensure that salary increases and performance assessments are consistent; however, this distorts the evaluation process and decreases employee motivation. In this MILP model, employee performance is only one parameter of several input parameters used in designing a salary policy that is independent of the results of performance-assessment values.

Estrategias para la rehabilitación energética en los albergues del Camino de Santiago: la Vía de la Plata

El Camino de Santiago, ha experimentado un crecimiento exponencial, durante los últimos años, llegando a triplicarse el número de peregrinos. Esto se ha traducido en la necesidad de aumentar el número de albergues a lo largo del Camino de Santiago. Por otro lado, nos encontramos con que reducir la demanda energética y las emisiones de CO2 son algunos de los principales retos que se plantea la arquitectura actual, para cumplir los objetivos marcados por la Unión Europea en el 2020, 2030 y 2050. Surge por tanto el proceso de la rehabilitación energética, como la opción más lógica y viable para comenzar a hablar de posibles soluciones a un problema global (búsqueda de construcciones más eficaces y sostenibles) solventando a su vez una problemática concreta (creciente demanda de albergues de peregrinos). La ruta concreta seleccionada como marco para llevar a cabo el análisis ha sido la de la Vía de la Plata, hilo conductor de historia a través de nuestro país y conexión natural entre las distintas zonas climáticas españolas (mediterránea, continental y atlántica). Para ello, cuatro ciudades han sido seleccionadas como objeto de análisis: Sevilla, Cáceres, Zamora y Santiago de Compostela. El objetivo central de esta investigación ha sido la selección y análisis de una serie de estrategias para la rehabilitación energética de los albergues de la Vía de Plata. Estas estrategias han sido clasificadas atendiendo al nivel de reforma arquitectónica (bajo, medio y alto), tipo de contexto (urbano y rural), propiedades de la envolvente, proporción y orientación de los huecos y la morfología del edificio. Se ha planteado como hipótesis de trabajo que, bajo los criterios bioclimáticos adecuados, y atendiendo a unas necesidades de confort ajustadas al uso transitorio de los albergues, su demanda energética podría verse reducida en algunas de las regiones climáticas españolas analizadas, dependiendo de la estrategia seleccionada. Se ha obtenido en total una casuística de más de 600 potenciales escenarios, que ha permitido obtener una visión global del funcionamiento de los albergues a lo largo de la península, atendiendo a diferentes parámetros, principalmente enfocados en torno a criterios de confort, demanda energética y emisiones de CO2. Como tendencia general, los albergues de la mitad más septentrional, presentan menores niveles de demanda energética y emisiones de CO2 en contextos urbanos, teniendo un gran impacto en su funcionamiento las estrategias planteadas. Esta tendencia se invierte en la zona sur de la península, representada en este caso por Cáceres y Sevilla, donde las demandas son más elevados, siendo especialmente sensibles al aumento de área de hueco y las consiguientes ganancias solares. En el contexto rural serán Zamora y Santiago las que presenten niveles de demanda energética más elevados, mientras que Cáceres y Sevilla presentan los niveles más elevados de emisiones de CO2, por su demanda predominante de refrigeración, directamente relacionada con el consumo eléctrico de los albergues. El conjunto de resultados obtenidos ha servido para analizar, a diferentes escalas y con distintos enfoques, el funcionamiento de las estrategias de rehabilitación energética propuestas, para cada una de las regiones climáticas seleccionadas. ABSTRACT Saint James Way has experienced a huge increase over the last years, reaching values up to three times higher than fifteen years ago. Therefore, the need for more hostels for the pilgrims has become an issue. On the other hand, reducing the energy demand and CO2 emissions within the built environment is one of the main challenges of current architecture, in order to achieve the proposed targets for 2020, 2030 and 2050 by the European Union. In this context, energy refurbishment shows up as the most logical and viable option, to discuss about potential solutions for global concerns (more sustainable and efficient constructions) solving at the same time particular issues (growing demand of pilgrim´s hostels). The selected route to undertake this analysis is known as “Vía de la Plata”, historical connection from the South to the North of Spain and a natural link among the different climate zones (Mediterranean, continental and atlantic). The four cities selected for the analysis as the most representatives of this route were; Sevilla, Cáceres, Zamora and Santiago de Compostela. The final target of this research was to select and analyse certain strategies for the energy refurbishment of the hostels on the mentioned Way. These strategies were classified according to the level of architectural refurbishment (low, medium or high), type of context (urban or rural), properties of the envelope, proportion and orientation of the windows and the morphology of the building. The hypothesis of the research is based on the believe that, under the right environmental criteria and with comfort levels adjusted to the transient type of use of the hostels, the energy demand could be reduced in some of the analysed climate regions, depending on the selected strategies. Six hundred potential scenarios were assessed, what allowed for a general vision on the hostels performance throughout the country, according to different parameters, focused on comfort criteria, energy demands and CO2 emissions. As a general trend, the hostels on the northern part of Spain show lower levels of energy demand and CO2 emissions in urban contexts, with a great impact of the proposed strategies on reducing the original demands. This trend is reversed on the South (Cáceres and Seville), were demands are higher, specially with greater glazing ratios. Hostels in the countryside show higher levels of demand on the North of Spain (Zamora and Santiago), but the cities on the South produce higher levels of CO2 emissions as they are mainly driven by cooling demands, directly related in this analysis to the electrical consumption of the hostels. Final results were used to understand, at different scales and from different points of view, how each one of the proposed strategies performs for each one of the selected climate zones.

Estratos arquitectónicos : conceptos, lógicas, sinopsis

La presente tesis doctoral se centra en la investigación del "estrato arquitectónico", manejando conceptos, lógicas y sinopsis como puntos organizativos, enlazados y superpuestos, que den paso a un marco propositivo que pueda ser simultáneamente articulado e independiente. Una situación que, ante nuevos desafíos, pretende ir más allá de una estricta definición de estrato o de su noción preconcebida descrita desde la superposición de diversos materiales. Todo ello a fin de revelar los diferentes perfiles del estrato y de la estratificación. Para ello, se abre y amplía el campo de estudio proyectual/procesual desdibujando los límites entre disciplinas –geología, filosofía, tecnología, arquitectura–. Y al mismo tiempo, se construye una cartografía del estrato arquitectónico asociada: a una taxonomía descriptora, a nuevas formulaciones, a pensamientos de personajes reconocibles y/o rescatados –como Rowe/Slutzky, Smithson, Parent/Virilio, Koolhaas, MVRDV, etc.–, y, por último, a nuevas lógicas proyectuales y operativas referidas al estrato, que fusionan conocimientos complejos. Unos contenidos que habitualmente no se presentan en investigaciones doctorales tradicionales –lo que permite afrontar nuevos cambios metodológicos, e imprimir un punto de partida para el desarrollo de futuras investigaciones o de otros posibles caminos emergentes–. Así, el discurso se impregna de nuevos referentes teóricos dentro de una misma mitología común (la del estrato). Un tema abordado con claves híbridas, es decir, con estudios selectivos y escritos coleccionados –analizados a partir de antecedentes encontrados y consolidados–, combinados con interpretaciones subyacentes en la arquitectura contemporánea –que pueden todavía encontrarse en fase experimental–. Una investigación que muestra la adaptación, la evolución y el cambio de la definición de "estrato arquitectónico", así como de su apariencia, utilización y aplicación a lo largo del tiempo, consecuencia de las nuevas necesidades y/o de las nuevas bases ideológicas ocasionadas por nuevos descubrimientos. Estratos arquitectónicos que dotan al espacio de profundidad –desde la bidimensionalidad– mediante la superposición de planos paralelos hacia la construcción de una nueva experiencia de estratificación fenomenológica. Estratos que generan estímulos y cambian su materialidad –de opacos a (en)tramados– creando apariencias y produciendo diversos efectos, para posteriormente exfoliarse y convertirse en estratos habitables. Estratos capturadores del espacio-tiempo, o de las dinámicas internas. Llegando incluso, con un último giro, a la era digital, donde el estrato informacional –que continua siendo independiente, autónomo y diverso, y que puede ser modificado, manipulado, suprimido o activable sin alterar el conjunto–, propicia obtener sistemas flexibles, relacionales, capaces de mutar o adaptarse, asociados a distintos niveles de organización dispositiva, que impulsan acciones y hacen emerger lógicas proyectuales. Estratos que surgen de forma elaborada o espontánea en el territorio urbano o natural (ciudad sobre ciudad, suelo sobre suelo), que se aplican extendiendo e hibridando el territorio (paisajes operativos), que son replanteados artificialmente como mecanismos edificatorios según las exigencias existentes (estratos programáticos, capas especializadas), y que se implantan como capas/layers en los programas informáticos utilizados como herramientas de diseño (multicapas, sistemas de intercambio informacional). Un trabajo que se estructura de manera multicapa lo que permite recorrer la tesis como un mapa de secuencias, saltar entre estratos de información, o seleccionar lecturas según intereses de pensamiento o acción arquitectónica. En consecuencia, una investigación sobre el "estrato arquitectónico" que conecta diversas disciplinas, que recopila distintos posicionamientos teórico/prácticos –lo que implica la introducción de parámetros y datos vivos–, y afronta un posicionamiento estratégico que vuelve a poner en valor el estrato arquitectónico –partiendo de estrategias formales que se han transformado en estrategias experimentales/operativas (a medida que el entorno se ha ido complejizando), siguiendo una estrategia conceptual e intelectual contemporánea, propia y específica–. ABSTRACT This PhD thesis is based on the research of "architectural stratum" using concepts, logical and synopsis as organizational, linked and overlapping points, which give way to a proactive framework that can be articulated and independent simultaneously. A situation that, faced with new challenges, aims to go beyond a strict definition of stratum or their preconceived notion described from the superposition of different materials. All this in order to reveal the different profiles of stratum and stratification. To do this, it opens and widens the field of project/process study, blurring the boundaries between disciplines –geology, philosophy, technology, architecture–. And, at the same time, a cartography of the architectural stratum is constructed, that associates with: descriptor taxonomy, new formulations, thoughts of recognizable and/or rescued characters, –as Rowe/Slutzky, Smithson, Parent/Virilio, Koolhaas, MVRDV, etc.–, and finally, a new project and operational logics referred to stratum, which merge complex knowledge. A content not usually presented in traditional doctoral research –which can face new methodological changes, and creates a starting point for future research or other possible emerging paths–. Thus, the work is imbued with new theoretical framework within a common mythology (stratum’s myth). An issue addressed with hybrid keys, that is, with selective studies and collected writings –analyzed starting from found and consolidated backgrounds–, combined with underlying performances on contemporary architecture –which can still be in experimental phase–. A research that shows adaptation, evolution and change of the definition of "architectural stratum", as well as their appearance, use and application throughout time, result of the new requirements and/or the new ideological foundations caused by new discoveries. Architectural strata that give depth to space –from two-dimensionality– by overlapping parallel planes towards the construction of a new experience of phenomenological stratification. Strata that generate stimuli and change their materiality –from opaque to lattice– creating appearances and producing various effects, for later exfoliating and becoming habitable strata. Strata that capture space-time or internal dynamics. Even reaching, with a final twist, the digital age, where the informational stratum –which remains independent, autonomous and diverse, and can be modified, manipulated, deleted or activated without altering the whole–, contribute to obtaining flexible, relational systems, able to mutate or adapt, associated with different levels of regulatory organization, that drive actions and make emerge project logics. Strata that arise elaborately or spontaneously in urban or natural territory (city upon city, floor upon floor), which apply expanding and hybridizing the territory (operational landscapes), which are artificially restated as building mechanisms according to existing requirements (strata program, specialized layers), which are implemented as layers in the software used as design tools (multilayer, systems of informational interchange). A work that is structured in a multi-layered way, which allows explore the thesis as a sequence map, jump between layers of information, or select readings according to an interest in thought or architectural action. Therefore, an investigation into the "architectural stratum" that connects different disciplines, which collects different theoretical/practical positions –which implies the introduction of live parameters and data– and faces a strategic positioning returning to value the architectural stratum –based on formal strategies that have become experimental/operational strategies (as the environment has become more complex), following a conceptual, intellectual, contemporary, own specific strategy–.

Ultraluminous X-ray sources with the SKA

The discovery almost three decades ago of non-nuclear, point-like X-ray sources with X-ray luminosities LX ≥ 3 × 1039 erg s−1 revolutionized the physics of black hole accretion. If of stellar origin, such Ultraluminous X-ray sources (ULXs) would have to accrete at super-Eddington rates in order to reach the observed high X-ray luminosities. Alternatively, ULXs could host sub-Eddington accreting intermediate-mass black holes, which are the long-time sought missing link between stellar and supermassive black holes and the possible seeds of the supermassive black holes that formed in the early Universe. The nature of ULXs can be better investigated in those cases for which a radio counterpart is detected. Radio observations of ULXs have revealed a wide variety of morphologies and source types, from compact and extended jets to radio nebulae and transient behaviours, providing the best observational evidence for the presence of an intermediate-mass black hole in some of them. The high sensitivity of the SKA will allow us to study the faintest ULX radio counterparts in the Local Universe as well as to detect new sources at much larger distances. It will thus perform a leap step in understanding ULXs, their accretion physics, and their possible role as seed black holes in supermassive black hole and galaxy growth.

Construction of Structures I in Moodle: a new teaching methodology in the Degree of Building Engineer

The subject of Construction of Structures I studies, from a constructive point of view and taking into account current legislation, reinforced concrete structures used in buildings, through the acquisition of knowledge and construction criteria required in the profession of a Technical Architect. The contents acquired in this course are essential for further professional development of technicians and are closely related to many of the subjects taught in the same or other courses of the Degree in Technical Architecture at the University of Alicante. The aim of this paper is to present, analyze and discuss the development of a new methodology proposed in the mentioned subject, as it supposed an important change in the traditional way of teaching Construction and Structures I. In order to incorporate new teaching tools in 2013-2014, the course has been implemented by using a Moodle software tool to promote blended learning with online exercises. Our Moodle community allows collaborative work within an open-source platform where teachers and students share a new and personalized learning environment. Students are easily used to the interface and the platform, value the constant connection with teachers or other fellows and completely agree with the possibility of making questions or share documents 24 hours a day. The proposed methodology consists of lectures and practical classes. In the lectures, the basics of each topic are discussed; class attendance, daily study and conducting scheduled exercises are indispensable. Practical classes allow to consolidate the knowledge gained in theory classes by solving professional exercises and actual construction problems related to structures, that shall be compulsorily delivered online. So, after the correction of the teacher and the subsequent feedback of students, practical exercises ensure lifelong learning of the student, who can download any kind of material at any time (constructive details, practical exercises and even corrected exams). Regarding the general evaluation system, goals achievement is assessed on an ongoing basis (65% of the final mark) along the course through written and graphic evidences in person and online, as well as a individual development of a workbook. In all cases, the acquisition of skills, the ability to synthesize, the capacity of logical and critical thinking are assessed. The other 35 % of the mark is evaluated by a complementary graphic exam. Participation in the computing platform is essential and the student is required to do and present, at least 90% of the practices proposed. Those who do not comply with the practices in each specific date could not be assessed continuously and may only choose the final exam. In conclusion, the subject of Construction of Structures I is essential in the development of the regulated profession of Technical Architect as they are considered, among other professional profiles, as specialists in construction of building structures. The use of a new communication platform and online teaching allows the acquisition of knowledge and constructive approaches in a continuous way, with a more direct and personal monitoring by the teacher that has been highly appreciated by almost 100% of the students. Ultimately, it is important to say that the use of Moodle in this subject is a very interesting tool, which was really well welcome by students in one of the densest and important subjects of the Degree of Technical Architecture.

Efeitos da microgravidade no raciocínio lógicomatemático, proposta de experimentação

O trabalho a seguir apresentado tem por objetivo procurar perceber se o nosso raciocínio se processa da mesma maneira em presença de microgravidade ou se, pelo contrário, sofre alguma alteração. A nossa questão foca-se mais especificamente num teste de matemática e, a partir da análise das diferentes variantes intervenientes na resolução do mesmo e das condições em causa (ambiente de microgravidade), inferirmos a possibilidade de o resultado do teste poder ser melhor do que quando elaborado em condições de gravidade normal.

Language, Identity, Politics-the Myth of Two Ukraines. Bertelsmann Policy Brief, April 2014

The narrative of two Ukraines – the existence of two separate cultural-political communities within one Ukrainian state – has accompanied the relatively short history of inde-pendent Ukraine from the very be-ginning. Articulated by Mykola Ryabchuk more than twenty years ago1 and seemingly logical and reasonable, it has become the fa-vourite narrative of many Ukrainian and international commentators and analysts. One of these Ukraines is pro-European, shares liberal democracy values, wants to join the European Union, “return to Europe” and, what is very im-portant, speaks Ukrainian. The symbolic centre of this Ukraine is Lviv. The other is nostalgic about the Soviet Union, has close rela-tions with contemporary Russia, is hostile towards the West and does not share “western” values. The language of this other Ukraine is Russian and its “capital” is Do-netsk. Taking on board this narra-tive simply means equating one’s region of residence, political views, and preferred language.

A imagem da mulher de meia-idade nos meios de comunicação social

O presente trabalho teve por finalidade investigar a posição ocupada pela mulher dita de meia-idade nos meios de comunicação social. Para tanto, foram selecionadas cerca de quinze Revistas Femininas, editadas pela Bloch e Abril Cultural, tendo sido as fotos e ilustrações apresentadas em tais veículos de comunicação, submetidas ã Análise de Conteúdo, para a qual se contou com uma equipe formada por quatorze juízes, selecionados aleatoriamente. Os estímulos apresentados foram classificados em três categorias, quais sejam, "mulher jovem", "mulher de meia-idade" e "mulher idosa", e os resultados obtidos submetidos a uma análise lógica e estatística. Efetuou-se um estudo sobre a condição da mulher, segundo as dimensões biológica, social e psicológica, considerados aspectos relativos à mítica feminina, além de um-breve histórico sobre a situação da mulher no contexto social do País. Foram, também, observados dados referentes ã Psicologia do Consumidor. A partir dos resultados obtidos constatou-se que a incidência de estímulos classificados como sendo mulheres de meia-idade não foi significativa, alcançando, a figura da mulher jovem, a quase totalidade dos estímulos apresentados em todas as revistas examinadas, mantendo-se elevada mesmo naquelas dirigidas, segundo as Editoras, primordialmente, às mulheres de mais idade. Observou-se, também, uma tendência acentuada a se classificar na categoria "jovem" figuras femininas que se apresentassem como sexualmente atraentes, fisicamente belas e, ainda, a de artistas populares - esta, mesmo naqueles casos em que, reconhecidamente, se sabia possuidoras de idade superior aos 43 anos. Desse modo, concluiu-se que a figura feminina correspondente à mulher considerada de meia-idade, inexiste como forma de apelo social, o que contribuiu, sobremaneira, para tornar ainda mais conflitivo um período já crítico em si mesmo, como o é o climatério.

Protective Eyewear Promotion: Applying Principles of Behaviour Change in the Design of a Squash Injury Prevention Programme

Eye injuries in squash have the potential to be severe. Although these injuries can be prevented through the use of protective eyewear, few players wear such eyewear. The aim of this paper is, to outline the behavioural principles guiding the design of a squash eyewear promotion initiative, the Protective Eyewear Promotion (PEP). Ecological principles of behaviour change were used to provide a comprehensive perspective on intrapersonal factors, policies and physical environmental influences of protective eyewear use. Results of baseline player surveys and venue manager inter-views were used to provide relevant and specific intervention content. At baseline, protective eyewear was not found to be readily available, and players' behaviours, knowledge and attitudes did not favour its use. The main components of PEP involved informing and educating both players and squash venue operators of the risk of eye injury and of appropriate protective eyewear, as well as assisting with the availability of the eyewear and offering incentives for players to use it. A structural strength of PEP was the strong collaborative links with the researchers of different disciplines, the squash governing body, eyewear manufacturers, squash venue personnel, as well as players. Attempts were made within the project structure to make provision for the future dissemination and sustainability of more widespread eye injury prevention measures in the sport of squash.

Foraging behaviour of Helicoverpa armigera first instar larvae on crop plants of different developmental stages

Understanding how insect pests forage on their food plants can help optimize management strategies. Helicoverpa armigera (Hubner) (Lep., Noctuidae) is a major polyphagous pest of agricultural crops worldwide. The immature stages feed and forage on crops at all stages of plant development, damaging fruiting and non-fruiting structures, yet very little is known about the influence of host type or stage on the location and behaviour of larvae. Through semi-continuous observation, we evaluated the foraging (movement and feeding) behaviours of H. armigera first instar larvae as well as the proportion of time spent at key locations on mungbean [Vigna radiata (L.) Wilczek] and pigeon pea [Cajanus cajan (L.) Millspaugh] of differing developmental stages: seedling- and mature (flowering/pod fill)-stage plants. Both host type and age affected the behaviour of larvae. Larvae spent more time in the upper parts of mature plants than on seedlings and tended to stay at the top of mature plants if they moved there. This difference was greater in pigeon pea than in mungbean. The proportion of time allocated to feeding on different parts of a plant differed with host and age. More feeding occurred in the top of mature pigeon pea plants but did not differ between mature and seedling mungbean plants. The duration of key behaviours did not differ between plant ages in either crop type and was similar between hosts although resting bouts were substantially longer on mungbeans. Thus a polyphagous species such as H. armigera does not forage in equivalent ways on different hosts in the first instar stage.

Quantum dynamics of a model for two Josephson-coupled Bose-Einstein condensates

In this work, we investigate the quantum dynamics of a model for two singlemode Bose-Einstein condensates which are coupled via Josephson tunnelling. Using direct numerical diagonalization of the Hamiltonian, we compute the time evolution of the expectation value for the relative particle number across a wide range of couplings. Our analysis shows that the system exhibits rich and complex behaviours varying between harmonic and non-harmonic oscillations, particularly around the threshold coupling between the delocalized and selftrapping phases. We show that these behaviours are dependent on both the initial state of the system and regime of the coupling. In addition, a study of the dynamics for the variance of the relative particle number expectation and the entanglement for different initial states is presented in detail.
