"La Santa Catalina de Alejandría" del Museo do Pobo Galego, una obra inédita de Mateo de Prado

Este artículo versa sobre la imagen, inédita y sin documentar, de Santa Catalina de Alejandría perteneciente al Museo do Pobo Galego (Santiago de Compostela). La primera parte está dedicada a su análisis morfológico, de manera que en ella, ejerciendo conscientemente como connoiseurs, determinamos aquellas señas de identidad que nos permiten, de acuerdo al juicio del ojo, atribuirla a Mateo de Prado. En la segunda, acometemos la interpretación de la obra desarrollando el carácter expresivo de su estilo a la luz de una historia de la cultura.This article is about the unknown and without documenting image of Saint Catherine that belongs to the Museo do Pobo Galego (Santiago de Compostela). The first part is focused on its morphological analysis in order to, acting consciously as connoisseurs, determine those identity signs that allow us, according to the judgment of the eye, attribute it to Mateo de Prado. In the second part, we carry out the interpretation of the work developing the expressive nature of its style in light of a history of the culture

Adversus cardinalis baronii, aliorumque opinionem. La defensa de la venida, y predicación evangélica, de Santiago en España en la génesis y circulación en Galicia del tipo iconográfico 'Santiago peregrino extático'

En los estudios consagrados a la iconografía de Santiago el Mayor se distinguen tradicionalmente tres tipos: apóstol, peregrino y caballero, para, a su vez, subdividirse la tipología de peregrino en Santiago caminando y Santiago estático de acuerdo a la actitud del santo. Con este artículo pretendemos contribuir a estos estudios al mostrar la aparición en la Galicia Moderna de una tercera variante, la cual, por consiguiente, viene a enriquecer la iconografía hasta el momento conocida del apóstol, tanto por la novedad que en sí misma supone, como por las profundas implicaciones históricas que creemos comporta. Consecuentemente, damos a conocer el tipo “Santiago peregrino extático”.In the studies devoted to James The Greater iconography three types are traditionally differentiated: apostle, pilgrim and knight, and, at the same time, the pilgrim type is subdivided according to the saintly attitude with James either walking or James standing. With this article, we aim to contribute to these studies showing the appearance of a third variety in the Modern Galicia, which therefore, enriches the iconography of the apostle known until now due to the innovative representation that implies by itself and also because of the deep historic implications that we think it involves. Consequently, we release “Ecstatic Pilgrim St. James” type

Conectando mundos distintos: ecología de migración en dos especies de hirundínidos

El comportamiento migratorio constituye una de las adaptaciones más espectaculares de los seres vivos frente a los cambios ambientales del planeta. Este comportamiento ha evolucionado en diversos grupos taxonómicos, desde mariposas a mamíferos, pero sin duda es en las aves donde ha encontrado su mayor desarrollo. Conocer dónde migran las aves siempre ha sido un misterio y no fue hasta finales del siglo XIX cuando comenzó el anillamiento científico. Desde los años ochenta, el desarrollo de nuevas técnicas de marcaje ha permitido obtener datos de gran precisión sobre el comportamiento migratorio. Esta información es necesaria para poder conservar adecuadamente poblaciones de aves migratorias en declive. En esta tesis doctoral, hemos utilizado análisis de isótopos estables y geolocalizadores para estudiar la ecología de migración en la golondrina común (Hirundo rustica) y el avión común (Delichon urbicum). En primer lugar, hemos descrito en detalle el comportamiento migratorio de la golondrina común reproductora en el sur de España. Además hemos identificado que la migración prenupcial es el principal nexo de unión entre lo que ocurre en África durante el invierno y lo que ocurre en Europa durante la temporada de reproducción. A continuación, hemos detectado que las condiciones ambientales experimentadas durante el invierno pueden tener consecuencias sobre la reproducción, lo que resulta sorprendente teniendo en cuenta que ambos eventos se encuentran separados varios meses en el tiempo y miles de kilómetros en distancia. Nuestros resultados revelan que el efecto del hábitat de invernada sobre el posterior éxito reproductor es muy complejo, pues depende de la edad, el sexo y de diferentes variables mediadoras que pueden interactuar entre sí. Aparte del propio valor científico de esta tesis doctoral, nuestros resultados tienen implicaciones en la conservación de especies migratorias y de aves insectívoras. De hecho, muchas especies propias de estos grupos se encuentran amenazadas de extinción o están sufriendo declives poblacionales.Premio Extraordinario de Doctorado U

Loss of largest and oldest individuals of the Montpellier snake correlates with recent warming in the southeastern Iberian Peninsula

The effects of climate change on organisms are now being extensively studied in many different taxa. However, the variation in body size, usually shrinkage in response to increasing temperature, has received little attention regarding to reptiles. During past periods of global warming, many organisms shrank in size, and current evidence and experiments manipulating temperature have shown a biomass decrease in some organisms with increasing temperatures. Here we test whether the body size of the Montpellier snake Malpolon monspessulanus from the southeastern Iberian Peninsula is changing and correlated with the increasing temperature in this region during a 39year period (1976–2014). We measured the snout–vent length (SVL) of vouchers in scientific collections to check for trends in adult body size at the population level in relation with temperature, while controlling for the age of the individuals (estimated by skeletochronology, n¼141). Given the great ontogenetic variation in body size of the study species, we categorized age in 3 classes: “young adults” (under 5 years old), “intermediate adults” (from 5 to 7 years old), and “old adults” (from 8 to 14 years old). By means of linear mixed models, we found a negative relationship between SVL of “old adults” and average annual temperature in the region during the lifetime of each individual. Our results indicate that largest and oldest individuals of the Montpellier Snake, that is, males because of strong sexual size dimorphism in this species, disappeared from the study population, and suggest that it occurred in response to rising environmental temperature.Junta de Andalucía RNM-25

Accessing a 'very, very secret garden' : exploring children's and young people's literacy practices using participatory research methods

Despite the wealth of publications on children’s and young people’s participation in research, the connections between participatory research methods (PRM) and literacy studies remain unclear. The aim of this paper is to understand why it is particularly pertinent to use PRM in literacy studies (particularly New Literacy Studies). In order to capture the complexity and plurality of these methods, we discuss two studies, one conducted with children in Chile and the other with young people in Québec (Canada). We argue that by using PRM, researchers can support participants in the appropriation of an alternative and potentially empowering view of literacy

A practical approach to network-based processing

The usage of general-purpose processors externally attached to routers to play virtually the role of active coprocessors seems a safe and cost-effective approach to add active network capabilities to existing routers. This paper reviews this router-assistant way of making active nodes, addresses the benefits and limitations of this technique, and describes a new platform based on it using an enhanced commercial router. The features new to this type of architecture are transparency, IPv4 and IPv6 support, and full control over layer 3 and above. A practical experience with two applications for path characterization and a transport gateway managing multi-QoS is described.Most of this work has been funded by the IST project GCAP (Global Communication Architecture and Protocols for new QoS services over IPv6 networks) IST-1999-10 504. Further development and application to practical scenarios is being supported by IST project Opium (Open Platform for Integration of UMTS Middleware) IST-2001-36063 and the Spanish MCYT under projects TEL99-0988-C02-01 and AURAS TIC2001-1650-C02-01.Publicad

El aprendizaje por proyectos como estrategia metodológica en el área de conocimiento del medio. Una experiencia didáctica sobre el rio Turia

El proyecto tiene como finalidad que los alumnos conozcan y comprendan todo lo sucedido en la riada del año 1957 que azotó Valencia y que fue el principio de la transformación de la ciudad. Fue tras este acontecimiento cuando se decidió desviar el cauce del rio por fuera de la ciudad, quedando el antiguo cauce abandonado, para posteriormente con el empeño del pueblo de Valencia, convertirlo en el grandioso jardín que hoy es el eje vertebrador de la ciudad y su mayor pulmón verde. En estas líneas se presenta una parte del contenido curricular del área de Conocimiento del medio, trabajado por un metodología por proyectos, analizando lo interesante de la misma

Professional Career of Women Graduates in Computing in Costa Rica: a Generational Study

The evolution in women´s professional career in computing has been studied very little. In a previous study (LAWWCC 2016) we reported results of an exploratory study that aimed to characterize the professional development model of people that studied Computer Sciences in Costa Rica, in terms of roles and industrial sectors with which they began their professional career and in which they report are currently working.. Surprisingly, no important gender differences were depicted amongst men and women. As a result, some valid concerns were raised regarding the question: do the results represent the behavior of women in all professional career stages? As a result, in this study, results are now grouped by generations. The aim of this study is to determine whether there are differences in these variables in the professional career evolution for different generations. Results are obtained from an online survey responded by 166 women professionals in Computer Sciences. Women are grouped in four generational categories: baby boomers, generation X, young and mature millennials. The main finding of this research is that the professional evolution of women, with respect to the role and sector in which they perform, revel different behaviors for women of different generations.Sociedad Argentina de Informática e Investigación Operativa (SADIO

Effect of DNA repair deficiencies on the cytotoxicity of resveratrol

Numerous preclinical studies have shown that the naturally-occurring polyphenol resveratrol may produce health-beneficial effects in a variety of disorders, including cancer, diabetes, Alzheimer, and cardiovascular diseases. Resveratrol has entered clinical trials for the prevention and treatment of several of these disorders. This polyphenol is also available in the market as a dietary supplement. Experimental data have shown, however, that resveratrol induces DNA damage in a variety of cells. Here we review such evidence and evaluate the cytotoxicity of resveratrol (MTT assay) in cells deficient in several major DNA repair pathways (i.e., homologous recombination, non-homologous end joining, base excision repair, nucleotide excision repair, mismatch repair, and Fanconi anemia repair). Cells deficient in base excision repair (EM9), nucleotide excision repair (UV4 and UV5) and Fanconi Anemia (KO40) were slightly hypersensitive to resveratrol-induced cytotoxicity with respect to their parental cells (AA8). Our results suggest that these pathways may participate in the repair of the DNA damage induced by resveratrol and that deficiencies in these pathways may confer hypersensitivity to the genotoxic activity of this dietary constituen
