Yasmin Levy's Ladino ballads and flamenco songs : background for students of Spanish. 'Yasmin Levy canta romances ladinos y canciones flamencas : orientación para los estudiantes de hispánicas'.

Resumen en español

The fat cat : a danish folktale.

Esta historia es un antiguo cuento del folklore danés. Una parte del texto es repetitivo, lo que permite a los niños terminar las oraciones cuando se lee en voz alta. El gato debe cuidad del caldero de las gachas, pero se las come todas, incluso la olla. A pesar de esto, el gato no está satisfecho y sigue comiendo todo lo que encuentra, incluídas las personas, y engordando, engordando, engordando, hasta que aparece un leñador.

La recogida de romances tradicionales por los alumnos : metodología y cuestionario.

Se pretende orientar y estimular a los profesores a llevar a cabo una actividad de recogida de romances tradicionales con los alumnos de lengua y literatura española de Bachillerato. Se expone la metodología seguida y las herramientas utilizadas durante esta actividad de recogida.

Contar, pintar y cantar en torno a los romances.

Se presenta la experiencia de un profesor de lengua y literatura en un instituto de bachillerato que pretende enseñar a sus alumnos qué son los romanes, a través de la puesta en marcha de actividades lúdicas que acerquen a los chicos a la poesía. En concreto, se pretende demostrar que los romances son un modo de comunicación popular, utilizado a lo largo de la historia y, para ello, se plantea realizar la clase fuera de toda rutina llevando a cabo un sistema innovador.

Romances y canciones populares cordobesas y jienenses.

Se ofrecen un conjunto de canciones, villancicos y romances procedentes de La Rambla (Córdoba) y Porcuna (Jaén), que han sido transmitidos a través de una tradición local y familiar. La muestra la constituyen once composiciones: ocho pertenecen al ciclo festivo de la Navidad, dos se cantaban el jueves lardero en Porcuna y, por último, una versión del más célebre romance de la cristiana cautiva. Los comentarios que se ofrecen se completan con notas al pie de los poemas.

La colección madrileña de romances de ciego que perteneció a Don Luis Usoz y Río.

Se recoge en este trabajo la colección madrileña de romances de ciego, que perteneció a Don Luis Usoz y Río y que en 1837 donó su viuda a la Biblioteca Nacional. La colección está formada por cuatro tomos que agrupan unos 600 pliegos. Aquí se presenta el primer volumen que permite tener una idea de la afición que hubo en España durante más de cinco siglos del XV al XX por los pliegos de cordel, sencillas canciones narrativas. La serie más extensa que incluye es la impresa en el taller madrileño de José María Marés entre 1845 y 1850 aunque el tramo más completo es el comprendido entre 1846 y 1848. En una primera parte se incluyen preliminares sobre el papel de los pliegos, en el contexto literario donde aparecen, y después se recogen las láminas con la colección. Por último, se incluyen un apéndice de documentación, uno musical y otro sobre libros e impresos de romances que poseyó Don Luis Usoz y Río..

Hacia una nueva flor de romances nuevos : experiencia didáctica con el Romancero tradicional.

Se presenta una experiencia didáctica que tiene como objetivos conocer qué es el Romancero tradicional: cuál es su métrica, su origen, su historia, clasificación, etc.; la pervivencia de los romances entre las familias de los alumnos y fomentar la creatividad de los alumnos. La experiencia consistía en la creación de romances basados en noticias de actualidad aparecidas en la prensa local y nacional.

Danish razors and Swedish rocks: Cosmology and the Bronze Age landscape

A recent study has suggested that the decorated Bronze Age metalwork of South Scandinavia depicted the path of the sun through the sky during the day and through the sea at night. At different stages in its journey it was accompanied by a horse or a ship. Similar images are found in prehistoric rock art, and this paper argues that, whilst there are important differences between the images in these two media, they also signal some of the same ideas.

The effects of spatial and temporal heterogeneity on the population dynamics of four animal species in a Danish landscape

Background: Variation in carrying capacity and population return rates is generally ignored in traditional studies of population dynamics. Variation is hard to study in the field because of difficulties controlling the environment in order to obtain statistical replicates, and because of the scale and expense of experimenting on populations. There may also be ethical issues. To circumvent these problems we used detailed simulations of the simultaneous behaviours of interacting animals in an accurate facsimile of a real Danish landscape. The models incorporate as much as possible of the behaviour and ecology of skylarks Alauda arvensis, voles Microtus agrestis, a ground beetle Bembidion lampros and a linyphiid spider Erigone atra. This allows us to quantify and evaluate the importance of spatial and temporal heterogeneity on the population dynamics of the four species. Results: Both spatial and temporal heterogeneity affected the relationship between population growth rate and population density in all four species. Spatial heterogeneity accounted for 23–30% of the variance in population growth rate after accounting for the effects of density, reflecting big differences in local carrying capacity associated with the landscape features important to individual species. Temporal heterogeneity accounted for 3–13% of the variance in vole, skylark and spider, but 43% in beetles. The associated temporal variation in carrying capacity would be problematic in traditional analyses of density dependence. Return rates were less than one in all species and essentially invariant in skylarks, spiders and beetles. Return rates varied over the landscape in voles, being slower where there were larger fluctuations in local population sizes. Conclusion: Our analyses estimated the traditional parameters of carrying capacities and return rates, but these are now seen as varying continuously over the landscape depending on habitat quality and the mechanisms of density dependence. The importance of our results lies in our demonstration that the effects of spatial and temporal heterogeneity must be accounted for if we are to have accurate predictive models for use in management and conservation. This is an area which until now has lacked an adequate theoretical framework and methodology.

Parallel performance and scalability experiments with the Danish Eulerian Model on the EPCC supercomputers

The Danish Eulerian Model (DEM) is a powerful air pollution model, designed to calculate the concentrations of various dangerous species over a large geographical region (e.g. Europe). It takes into account the main physical and chemical processes between these species, the actual meteorological conditions, emissions, etc.. This is a huge computational task and requires significant resources of storage and CPU time. Parallel computing is essential for the efficient practical use of the model. Some efficient parallel versions of the model were created over the past several years. A suitable parallel version of DEM by using the Message Passing Interface library (AIPI) was implemented on two powerful supercomputers of the EPCC - Edinburgh, available via the HPC-Europa programme for transnational access to research infrastructures in EC: a Sun Fire E15K and an IBM HPCx cluster. Although the implementation is in principal, the same for both supercomputers, few modifications had to be done for successful porting of the code on the IBM HPCx cluster. Performance analysis and parallel optimization was done next. Results from bench marking experiments will be presented in this paper. Another set of experiments was carried out in order to investigate the sensitivity of the model to variation of some chemical rate constants in the chemical submodel. Certain modifications of the code were necessary to be done in accordance with this task. The obtained results will be used for further sensitivity analysis Studies by using Monte Carlo simulation.

Parallel implementation and one year experiments with the Danish Eulerian Model

Large scale air pollution models are powerful tools, designed to meet the increasing demand in different environmental studies. The atmosphere is the most dynamic component of the environment, where the pollutants can be moved quickly on far distnce. Therefore the air pollution modeling must be done in a large computational domain. Moreover, all relevant physical, chemical and photochemical processes must be taken into account. In such complex models operator splitting is very often applied in order to achieve sufficient accuracy as well as efficiency of the numerical solution. The Danish Eulerian Model (DEM) is one of the most advanced such models. Its space domain (4800 × 4800 km) covers Europe, most of the Mediterian and neighboring parts of Asia and the Atlantic Ocean. Efficient parallelization is crucial for the performance and practical capabilities of this huge computational model. Different splitting schemes, based on the main processes mentioned above, have been implemented and tested with respect to accuracy and performance in the new version of DEM. Some numerical results of these experiments are presented in this paper.
