Memory, iconography and landscape: a purpose of using photography as a geographic source

La memoria es una facultad humana de inequívoca importancia en el manejo de los conocimientos. Los localiza temporal y espacialmente y deviene un factor esencial de nuestro reconocimiento, tanto individual como socialmente: “memoria personal versus memoria colectiva”. a) Una de las opciones metodológicas de la Geografía, la llamada “histórica”, en la que este trabajo se inserta, procesa las distintas fuentes y datos del pasado para alcanzar explicaciones del presente. b) De entre ellas, la fotografía ha alcanzado un valor relevante especialmente en el análisis de procesos de cambios paisajísticos veloces, los que es posible disponer de “series fotográficas” capaces de fijar el proceso en imágenes, trasuntos fieles de la realidad. c) Desde esas perspectivas metodológicas, se presente el estudio de un caso: la orilla del Guadalquivir por Coria del Río (Sevilla).The memory is a human faculty of clear importance in the management of knowledge. It locates them temporally and spatially and becomes an essential factor for our identity recognition, both individually and socially: “personal memory versus collective memory”. a) one of the methodological options of geography, the “historical” call in which this work is inserted, processing the various sources and data of the past to achieve the present explanations. b) among them, photography has reached a clear value especially in the analysis of processes of landscape changes fast and in cases in which it is possible to have “photographic series” that is able to set the process in pictures, faithful transcripts in reality. c) from those methodological perspectives, will present a case study: the banks of the Guadalquivir by Coria del Río (Seville)

A Sevillian Bed for The Baron of Petrapesia: Masterpiece of the Painters Gonzalo de Flores and Hernando de Alcalá

El estudio de las relaciones culturales ente Sevilla e Italia en la Edad Moderna, nos condujo al hallazgo de un contrato en el Archivo Histórico Provincial de la ciudad, en el que se recogía el acuerdo entre Matteo Barresi, un barón siciliano, y dos pintores, poco conocidos hasta este momento, Gonzalo de Flores y Hernando de Alcalá, para la realización de la decoración de cuatro paños para una cama. El resultado nos aporta no sólo una serie de noticias del panorama artístico y social de la Sevilla en el año de la boda de Carlos V, sino también datos desconocidos sobre la biografía del dicho noble.The study of the cultural relations between Seville and Italy during the Modern Age, lead us to the discovering of a contract in the Archivo Histórico Provincial of the city, which show the agreement between Matteo Barresi, a Sicilian baron, and two painters, nearly unknown until this moment, Gonzalo de Flores y Hernando de Alcalá, for the realization of the decoration of four panels of canvas for a bed. The result gives us not only a sort of news about the artistic and social environment of Seville during the Charles V’s wedding time, but also new information about the Italian nobleman biography

The fixed-point property in Banach spaces containing a copy of c0

We prove that every Banach space containing an isomorphic copy of c0 fails to have the fixed-point property for asymptotically nonexpansive mappings with respect to some locally convex topology which is coarser than the weak topology. If the copy of c0 is asymptotically isometric, this result can be improved, because we can prove the failure of the fixed-point property for nonexpansive mappings.Dirección General de Investigación Científica y TécnicaJunta de Andalucí

Fixed points and common fixed points for orbit-nonexpansive mappings in metric spaces

In this paper we introduce an interlacing condition on the elements of a family of operators that allows us to gather together a number of results on fixed points and common fixed points for single and families of mappings defined on metric spaces. The innovative concept studied here deals with nonexpansivity conditions with respect to orbits and under assumptions that only depend on the features of the closed balls of the metric space
