Vicent Garcia, poeta europeu

Si hi ha un període postmedieval similar al nostre d’avui en la història literària catalana en el qual els nostres escriptors -trencant radicalment amb una tradició ja obsoleta (com era la del cinc-cents en la seva major part)- es posen a l’alçada dels corrents literaris europeus, aquest és el període barroc (cf. Rossich 1984 ). El text que em proposo analitzar i comparar il·lustra perfectament aquesta circumstància

Dynamic social representations of the 2009 H1N1 pandemic: Shifting patterns of sense-making and blame

We investigate dynamics of public perceptions of the 2009 H1N1 influenza pandemic to understand changing patterns of sense-making and blame regarding the outbreak of emerging infectious diseases. We draw on social representation theory combined with a dramaturgical perspective to identify changes in how various collectives are depicted over the course of the pandemic, according to three roles: heroes, villains and victims. Quantitative results based on content analysis of three cross-sectional waves of interviews show a shift from mentions of distant collectives (e.g., far-flung countries) at Wave 1 to local collectives (e.g., risk groups) as the pandemic became of more immediate concern (Wave 2) and declined (Wave 3). Semi-automated content analysis of media coverage shows similar results. Thematic analyses of the discourse associated with collectives revealed that many were consistently perceived as heroes, villains and victims.

Who are Cerverí's worst enemies?

Those who heard the piece sung at the royal court of Aragon, where it was composed, were more than likely familiar with its author, the troubadour Cerverí de Girona, one of the most significant poets of the time. If later readers knew the poem from a compilation similar to the only chansonnier that has preserved it until present times, they would have had access to at least one hundred and three other pieces by the same troubadour, which give useful clues to understand this self-referential piece

Notes sobre la tradició textual del Llibre dels àngels de Francesc Eiximenis

L’edició completa de les obres de Francesc Eiximenis és una empresa filològica que presenta dificultats objectives, no només perquè les obres tenen un pes material més que considerable, sinó també per la gran quantitat de testimonis manuscrits i impresos que cal col·lacionar. Amb l’objectiu d’ajudar a superar aquestes dificultats, ja fa alguns anys que l’Institut de Llengua i Cultura Catalanes de la Universitat de Girona ha emprès la publicació de les Obres de Francesc Eiximenis, i avui afortunadament podem afirmar que les obres d’Eiximenis, especialment les inèdites, ja tenen equips de treball que s’ocupen de la preparació de les edicions corresponents. Paral·lelament, i en la mateixa línia de treball, s’ha iniciat una nova descripció integral dels testimonis manuscrits i impresos de Francesc Eiximenis, els primers resultats de la qual es podran consultar en línia ben aviat. En el marc que acabo de descriure fa temps que un equip treballa en l’edició crítica del Llibre dels àngels (en endavant LA), escrit a València el 1392

Borges: fervor de Dante

Ya son más de una docena los estudios dedicados a la asimilación de Dante en la obra de Borges, pero la dispersión bibliográfica y la carencia de una edición crítica de los textos borgesianos pueden suponer un obstáculo serio para quien pretenda estudiar este aspecto de forma sistemática. Por ello, en este artículo se ofrece una síntesis de los problemas que entraña la presencia de Dante en Borges (cronología de su presencia, tendencias de la crítica y significado de Dante en la poética del escritor argentino). También se ofrece un corpus, ordenado y completo, de las menciones de Dante en las narraciones, ensayos y poemas del bonaerense, que incluye los ensayos que este dedicó a la Comedia, los recuerdos autobiográficos que le conciernen, las menciones generales y precisas, y los comentaristas de Dante que citó a lo largo de sus textos

Super-resolution of remotely sensed images with variable-pixel linear reconstruction

This paper describes the development and applications of a super-resolution method, known as Super-Resolution Variable-Pixel Linear Reconstruction. The algorithm works combining different lower resolution images in order to obtain, as a result, a higher resolution image. We show that it can make significant spatial resolution improvements to satellite images of the Earth¿s surface allowing recognition of objects with size approaching the limiting spatial resolution of the lower resolution images. The algorithm is based on the Variable-Pixel Linear Reconstruction algorithm developed by Fruchter and Hook, a well-known method in astronomy but never used for Earth remote sensing purposes. The algorithm preserves photometry, can weight input images according to the statistical significance of each pixel, and removes the effect of geometric distortion on both image shape and photometry. In this paper, we describe its development for remote sensing purposes, show the usefulness of the algorithm working with images as different to the astronomical images as the remote sensing ones, and show applications to: 1) a set of simulated multispectral images obtained from a real Quickbird image; and 2) a set of multispectral real Landsat Enhanced Thematic Mapper Plus (ETM+) images. These examples show that the algorithm provides a substantial improvement in limiting spatial resolution for both simulated and real data sets without significantly altering the multispectral content of the input low-resolution images, without amplifying the noise, and with very few artifacts.

Avaluació de revistes i avaluació de la recerca en humanitats i ciències socials a Catalunya: aproximació a un problema

The evaluation of the quality and impact of journals as a starting point to systematise the quality of research is an indirect method commonly used for obtaining information for systematic and major evaluation efforts, such as those needed for public tenders to aid projects and research groups. Nevertheless, this method runs into an important obstacle: preparing rankings of journals in the humanities and social sciences is considerably more complex than for those on experimental, biomedical or technological sciences. Cultural, linguistic and territorial components of research in the humanities and social sciences radically question the international rankings. Within this context, the article presents the experience of a study-in-progress whose intention is to evaluate the rankings of journals in the humanities and social sciences published in 1997 by the Generalitat de Catalunya. Even thought an attempt was made to bring this type of titles closer to the Catalan community of researchers, the initiative has been frequently surrounded by controversy and criticism and, at the present, does not enjoy the needed recognition of the Catalan academic sector.

Domain Adaptation in remote sensing: increasing the portability of land-cover classifiers

Among the types of remote sensing acquisitions, optical images are certainly one of the most widely relied upon data sources for Earth observation. They provide detailed measurements of the electromagnetic radiation reflected or emitted by each pixel in the scene. Through a process termed supervised land-cover classification, this allows to automatically yet accurately distinguish objects at the surface of our planet. In this respect, when producing a land-cover map of the surveyed area, the availability of training examples representative of each thematic class is crucial for the success of the classification procedure. However, in real applications, due to several constraints on the sample collection process, labeled pixels are usually scarce. When analyzing an image for which those key samples are unavailable, a viable solution consists in resorting to the ground truth data of other previously acquired images. This option is attractive but several factors such as atmospheric, ground and acquisition conditions can cause radiometric differences between the images, hindering therefore the transfer of knowledge from one image to another. The goal of this Thesis is to supply remote sensing image analysts with suitable processing techniques to ensure a robust portability of the classification models across different images. The ultimate purpose is to map the land-cover classes over large spatial and temporal extents with minimal ground information. To overcome, or simply quantify, the observed shifts in the statistical distribution of the spectra of the materials, we study four approaches issued from the field of machine learning. First, we propose a strategy to intelligently sample the image of interest to collect the labels only in correspondence of the most useful pixels. This iterative routine is based on a constant evaluation of the pertinence to the new image of the initial training data actually belonging to a different image. Second, an approach to reduce the radiometric differences among the images by projecting the respective pixels in a common new data space is presented. We analyze a kernel-based feature extraction framework suited for such problems, showing that, after this relative normalization, the cross-image generalization abilities of a classifier are highly increased. Third, we test a new data-driven measure of distance between probability distributions to assess the distortions caused by differences in the acquisition geometry affecting series of multi-angle images. Also, we gauge the portability of classification models through the sequences. In both exercises, the efficacy of classic physically- and statistically-based normalization methods is discussed. Finally, we explore a new family of approaches based on sparse representations of the samples to reciprocally convert the data space of two images. The projection function bridging the images allows a synthesis of new pixels with more similar characteristics ultimately facilitating the land-cover mapping across images.

Diagnostic techniques applied in geostatistics for agricultural data analysis

The structural modeling of spatial dependence, using a geostatistical approach, is an indispensable tool to determine parameters that define this structure, applied on interpolation of values at unsampled points by kriging techniques. However, the estimation of parameters can be greatly affected by the presence of atypical observations in sampled data. The purpose of this study was to use diagnostic techniques in Gaussian spatial linear models in geostatistics to evaluate the sensitivity of maximum likelihood and restrict maximum likelihood estimators to small perturbations in these data. For this purpose, studies with simulated and experimental data were conducted. Results with simulated data showed that the diagnostic techniques were efficient to identify the perturbation in data. The results with real data indicated that atypical values among the sampled data may have a strong influence on thematic maps, thus changing the spatial dependence structure. The application of diagnostic techniques should be part of any geostatistical analysis, to ensure a better quality of the information from thematic maps.

Le prêt à intérêt dans l'Antiquité préchrétienne : Jérusalem, Athènes, Rome : étude juridique, philosophique et historiographique

Le prêt à intérêt était pratiqué par tous les peuples de l'Antiquité préchrétienne, à l'exception du peuple d'Israël. L'auteur examine d'abord l'interdiction du prêt à intérêt dans l'Ancien Testament. Il expose ensuite la pratique du prêt à intérêt en Grèce, avant de détailler les critiques d'Aristote. Enfin, l'auteur retrace l'évolution du prêt (mutuum) et de la réglementation de l'intérêt à Rome, des origines à Constantin. Il met l'accent sur trois grandes controverses parmi les romanistes modernes (XVIe - XXIe s.) : sur le nexum, sur la centesima et, surtout, sur le mystérieux fenus unciarium, le taux d'intérêt fixé par les Douze Tables, pour lequel l'éventail des interprétations va de 1 à 100 % par an ! L'auteur recense les opinions de plus de 400 juristes et historiens, discute les plus importantes et propose sa conclusion. The loan at interest was used by all the peoples of pre-Christian Antiquity, excepting the people of Israel. The author first focuses on the prohibition of lending at interest in the Old Testament. He then explores the use of loans at interest in Greece before examining Aristotle's criticism. Eventually, the author follows the evolution of loan (mutuum) and interest regulation in Rome, from the origins to Constantine. Three great controversies among modern Roman law scholars (16th - 21th) are considered: nexum, centesima and above all, the mysterious fenus unciarium, the interest rate defined by the Twelve Tables, for which the range of interpretations varies between 1 and 100% per year! The author gives an inventory of more than 400 opinions expressed by jurists and historians, discusses the most important ones and suggests a solution.
