Sobre l´elecció de bisbes durant el franquisme: els casos de Narcís Jubany (1964) i Jaume Camprodon (1973) per a la seu de Girona

L'objectiu d'aquest article és presentar les circumstàncies i algunes de les actuacions que es produïren a l'hora de fer els dos nomenaments que afectaren la diòcesi de Girona. El primer, per causa de la mort del bisbe Cartañà, enregistrada el 1963; i el segon, motivat pel trasllat del bisbe Jubany a Barcelona, el 1971

El Camí de Sant Jaume en la provincia de Girona

En primer lugar se identifican las distintas rutas del Camí de Sant Jaume en la provincia de Girona con el objetivo de determinar cuáles han sido las principales rutas que los peregrinos han utilizado para su peregrinación hacia Santiago de Compostela dentro de la provincia de Girona. En segundo lugar se establecen los elementos que determinan que un itinerario concreto esté comprendido en el Camino de Santiago para lo cual se analizan las rutas y se buscan los componentes que tienen una relación directa con la peregrinación a Santiago de Compostela, bien por ser elementos descriptivos del Santo, bien por ser elementos que a lo largo de la historia se han atribuido a los peregrinos que peregrina a Santiago de Compostela. En tercer lugar se analiza el recorrido del Camí de Sant Jaume elegido por la Generalitat de Catalunya, se examinan los servicios que ofrece y las carencias o insuficiencias que posee. Finalmente se establece la confección de propuestas de mejora y las acciones pertinentes para corregir las debilidades que en su caso puedan tener estos itinerarios

Jaume Serra Hunter i la teoria de la cultura en el Noucentisme

Catalan modern and contemporary philosophy has traditionally been little studied so strictly to historical and political reasons for more or less the same conviction that is compared with literature and even in historiography, it is a minor contribution. Some of the characters in the world of philosophy has been the Catalan Jaume Serra Hunter charismatic and versatile, whom history has done justice. Like many others, was persecuted in the Franco regime, declared outlawed and persecuted and exiled, first to France and then Mexico. This research aims to discover him and his huge role as a politician. But above all, I want to convey their deep love for culture and fierce defense that he did, especially Catalan, is following in philosophical discourse of his work. I figure Serra Hunter claim their struggle for cultural cohesion through its philosophy, making it reach everyone. I want to show how he worked in a time of crisis in society, culture and education, to overcome the crisis of philosophy as a guide. Serra Hunter lived a very difficult time for philosophy. But he wanted to bring all cultures. It is a philosophy that dealing with the issues may be even a sort of advanced in the world and some of the problems it has today. According to him, philosophy should be more human and more alive and present in all the different curriculum of any educational plan.

Social network measures for "nosduocentered" networks, their predictive power on performance

Our purpose in this article is to define a network structure which is based on two egos instead of the egocentered (one ego) or the complete network (n egos). We describe the characteristics and properties for this kind of network which we call “nosduocentered network”, comparing it with complete and egocentered networks. The key point for this kind of network is that relations exist between the two main egos and all alters, but relations among others are not observed. After that, we use new social network measures adapted to the nosduocentered network, some of which are based on measures for complete networks such as degree, betweenness, closeness centrality or density, while some others are tailormade for nosduocentered networks. We specify three regression models to predict research performance of PhD students based on these social network measures for different networks such as advice, collaboration, emotional support and trust. Data used are from Slovenian PhD students and their s

Grain size analyses in tin-lead glazes based on 2d-sections

A problem in the archaeometric classification of Catalan Renaissance pottery is the fact, that the clay supply of the pottery workshops was centrally organized by guilds, and therefore usually all potters of a single production centre produced chemically similar ceramics. However, analysing the glazes of the ware usually a large number of inclusions in the glaze is found, which reveal technological differences between single workshops. These inclusions have been used by the potters in order to opacify the transparent glaze and to achieve a white background for further decoration. In order to distinguish different technological preparation procedures of the single workshops, at a Scanning Electron Microscope the chemical composition of those inclusions as well as their size in the two-dimensional cut is recorded. Based on the latter, a frequency distribution of the apparent diameters is estimated for each sample and type of inclusion. Following an approach by S.D. Wicksell (1925), it is principally possible to transform the distributions of the apparent 2D-diameters back to those of the true three-dimensional bodies. The applicability of this approach and its practical problems are examined using different ways of kernel density estimation and Monte-Carlo tests of the methodology. Finally, it is tested in how far the obtained frequency distributions can be used to classify the pottery

Refinement criteria for global illumination using convex funcions

In several computer graphics areas, a refinement criterion is often needed to decide whether to go on or to stop sampling a signal. When the sampled values are homogeneous enough, we assume that they represent the signal fairly well and we do not need further refinement, otherwise more samples are required, possibly with adaptive subdivision of the domain. For this purpose, a criterion which is very sensitive to variability is necessary. In this paper, we present a family of discrimination measures, the f-divergences, meeting this requirement. These convex functions have been well studied and successfully applied to image processing and several areas of engineering. Two applications to global illumination are shown: oracles for hierarchical radiosity and criteria for adaptive refinement in ray-tracing. We obtain significantly better results than with classic criteria, showing that f-divergences are worth further investigation in computer graphics. Also a discrimination measure based on entropy of the samples for refinement in ray-tracing is introduced. The recursive decomposition of entropy provides us with a natural method to deal with the adaptive subdivision of the sampling region

Revisiting the compositional data. Some fundamental questions and new prospects in Archaeometry and Archaeology

In this paper we examine the problem of compositional data from a different starting point. Chemical compositional data, as used in provenance studies on archaeological materials, will be approached from the measurement theory. The results will show, in a very intuitive way that chemical data can only be treated by using the approach developed for compositional data. It will be shown that compositional data analysis is a particular case in projective geometry, when the projective coordinates are in the positive orthant, and they have the properties of logarithmic interval metrics. Moreover, it will be shown that this approach can be extended to a very large number of applications, including shape analysis. This will be exemplified with a case study in architecture of Early Christian churches dated back to the 5th-7th centuries AD
