Els Naturals i el rei natural en la Catalunya de la Guerra dels Segadors: a propòsit d´un sermó de Gaspar Sala (1641)

La guerra dels Segadors (1640-1652/59) va ser també una guerra d'idees o arguments polítics. A diferència, però, d'altres conflictes anteriors (com ara l'anomenada guerra civil catalana de mitjan segle xv), aquests arguments antagònics conegueren (al Principat i fins i tot mes enllà) una difusió sense precedents; sobretot pel fet que s'expressaren tot sovint per la via impresa

El poder de las imágenes en los "Diálogos de Medallas, inscriciones y otras antigüedades" (1587) de don Antonio Agustín

Un aspecto realmente sorprendente y fascinante, el cual hasta ahora no se ha prestado demasiada atención, es el poder de las imágenes en el famosísimo y reputado libro de Don Antonio Agustín, los Dialogos de Medallas, publicado en Tarragona por Felipe Mey en el año 15872. Las imágenes que ilustran este libro fueron las responsables de una serie de fenómenos de gran importancia en la génesis de esta edición. El primero de ellos fue la dilatada espera de la edición a causa de la recepción de los grabados. El segundo hace referencia a la misma ordenación de las imágenes, ya que mientras muchos libros de numismática las organizan atendiendo a sucronología, a sus medidas o al material en el que están labradas, las imágenes del libro de Agustín se organizan teniendo en cuenta el texto, hecho que provoca que estos iconos tengan un fuerte carácter didascálico. En tercer lugar, hay que resaltar la pertinaz voluntad y los probados esfuerzos de Agustín para conseguir unas imágenes de calidad en Roma, puesto que los talleres gráficos españoles dejaban mucho que desear en esta época. Y por último, cabe subrayar que su muerte en Tarragona en mayo de 1586, interrumpió el proceso del grabado de las monedas, hecho que motivo que solamente estuvieran ilustrados los dos primeros diálogos de su libro. Pero antes de entrar en la valoración de estos fenómenos veamos unos breves prologomenos.

El mito clásico en la novela pastoril: Jorge de Montemayor y Gaspar Gil Polo

Este artículo intenta analizar y sistematizar la huella del mito clásico en algunos autores del siglo XVI, cuyo aparato crítico es una herramienta importante para determinar el grado de continuación de elementos griegos y latinos en la novela pastoril, y establecer de esta manera un balance de la utilización mítica de este género de la literatura española.

De Francisco a Marco Antonio Aldana pasando por Gaspar

It is traditionally considered that the «Aldana», whom Gaspar Gil Polo praises at the end of his «Canto de Turia» (1564), was Francisco de Aldana, the «divino». It is nonetheless more probable that it was in fact rather the Valencian poet, Marco Antonio Aldana, almost forgotten today, but very much in the public eye within the cultivated circles of the end of the sixteenth century Valencia

Interest rate determination in the interbank market

The purpose of this paper is to study the determinants of equilibrium in the market for daily funds. We use the EONIA panel database which includes daily information on the lending rates applied by contributing commercial banks. The data clearly shows an increase in both the time series volatility and the cross section dispersion of rates towards the end of the reserve maintenance period. These increases are highly correlated. With respect to quantities, we find that the volume of trade as well as the use of the standing facilities are also larger at the end of the maintenance period. Our theoretical model shows how the operational framework of monetary policy causes a reduction in the elasticity of the supply of funds by banks throughout the reserve maintenance period. This reduction in the elasticity together with market segmentation and heterogeneity are able to generate distributions for the interest rates and quantities traded with the same properties as in the data.

GAPS: generador de aplicaciones sintéticas

Gaps es un generador de aplicaciones sintéticas de estructura compuesta Master/Worker de pipelines. Para crear una aplicación sintética, el investigador utilizará Gaspar, que recibe un fichero de texto con los parámetros de la aplicación a generar: cantidad de workers, etapas, tamaño de mensaje a enviar, etc., y genera un fichero con las propiedades de cada etapa. A partir de estos datos, Gaps, que esta hecho en C con MPI, genera y ejecuta la aplicación paralela. Estas aplicaciones se utilizan para comprobar en un entorno real los estudios analíticos que constituyen el modelo de rendimiento y sintonización dinámica.

N-dimensional dynamical systems exploiting instabilities in full

We report experimental and numerical results showing how certain N-dimensional dynamical systems are able to exhibit complex time evolutions based on the nonlinear combination of N-1 oscillation modes. The experiments have been done with a family of thermo-optical systems of effective dynamical dimension varying from 1 to 6. The corresponding mathematical model is an N-dimensional vector field based on a scalar-valued nonlinear function of a single variable that is a linear combination of all the dynamic variables. We show how the complex evolutions appear associated with the occurrence of successive Hopf bifurcations in a saddle-node pair of fixed points up to exhaust their instability capabilities in N dimensions. For this reason the observed phenomenon is denoted as the full instability behavior of the dynamical system. The process through which the attractor responsible for the observed time evolution is formed may be rather complex and difficult to characterize. Nevertheless, the well-organized structure of the time signals suggests some generic mechanism of nonlinear mode mixing that we associate with the cluster of invariant sets emerging from the pair of fixed points and with the influence of the neighboring saddle sets on the flow nearby the attractor. The generation of invariant tori is likely during the full instability development and the global process may be considered as a generalized Landau scenario for the emergence of irregular and complex behavior through the nonlinear superposition of oscillatory motions

UBVRI photoelectric photometry of nearby stars. II.

A second set of UBVRI photometry results for nearby stars of Gliese's (1969) catalog and its supplements, including in this case some multiple systems, are presented. Most of the observations were carried out between July 1984 and December 1985 at Calar Alto with the 1.23-m Centro Astronomico Hispano-Aleman telescope and the 1.52-m Observatorio Astronomico Nacional telescope. The number of observations of program and standard stars for the six runs and the final results for 60 stars are presented.

UBVRI photoelectric photometry of nearby stars

In order to complete the photometric data of the Gliese (1969) 'Catalog of Nearby Stars', and in addition use these data for the Hipparcos space astrometry mission, program stars have been selected from the catalog and its supplements on the basis of their having an incomplete set of UBVRI photometric data of magnitude lower than 13. The program developed rejects determinations of any magnitude or color index having a residual greater than 2(sigma-prime), where sigma-prime is the standard deviation for the determinations of unit weight.

UBVRI photoelectric photometry of high proper motion stars

UBVRI photoelectric photometry is presented for 269 late spectral type, high proper motion stars belonging to the 'Lowell Proper Motion Survey' and included in the present version of the Hipparcos Input Catalogue. The observations and data reduction are described. The external errors obtained by comparison of the results with those obtained in other studies are presented.

UBVRI photometry of G, K, M Hipparcos stars

UBVRI data are presented for a set of 229 late-type stars, most of them being high proper motion stars. All these data are part of the Input Catalog planned observations for the Hipparcos mission.

UVBY-Beta Photometry for 67 Stars in the Region of Alpha-Persei

UVBY-Beta photometric data are presented for 67 stars in the region of alpha-Persei and their relationship to the cluster is analyzed. These data allowed us to confirm at least 16 new members of the alpha-Persei open cluster.

UBVRI photometry of G, K, M Hipparcos stars. II.

As indicated by Grenon (1989), the data of the present series of reports on the UBVRI photometry of late-type stars in the Hipparcos Input Catalog are to be employed in computations of Hipparcos observing time, as well as in evaluating the observability of faint stars by the satellite. Attention is here given to late type stars in the V = 8-12 range, including distant red giants in the Galactic plane (Hipparcos proposal 189), as well as high proper motion stars included in the G, LTT, LP, and MCC catalogs.
