Libro acerca de la vida y obra del numismático de Puerto Rico Luis Antonio Rodríguez Vázquez. Se incluye sus experiencias en diferentes facetas como la numismática, arqueología, bibliofilia y otras. El autor narra sus experiencias de los viajes realizados a algunas islas del Caribe y datos sobre la historia y cultura de estas. También incluye información sobre la historia monetaria de Puerto Rico y su bibliografía completa de 541 artículos publicados en diez periódicos de Puerto Rico. Esta es la primera autobiografía publicada por un numismático en Puerto Rico. Debido al interés del autor sobre el sincretismo religioso y la antropología hace un recuento de sus experiencias obtenidas del estudio del espiritismo y la santería en Puerto Rico. La información de este libro es muy interesante y variada lo cual hace que su lectura sea amena y divertida.
Since 1993, more than five hundred women and girls have been murdered in Ciudad Juárez across the border from El Paso, Texas. At least a third have been sexually violated and mutilated as well. Thousands more have been reported missing and remain unaccounted for. The crimes have been poorly investigated and have gone unpunished and unresolved by Mexican authorities, thus creating an epidemic of misogynist violence on an increasingly globalized U.S.-Mexico border. This book, the first anthology to focus exclusively on the Juárez femicides, as the crimes have come to be known, compiles several different scholarly "interventions" from diverse perspectives, including feminism, Marxism, critica...
The basic principles guiding sensing, perception and action in bio systems seem to rely on highly organised spatial-temporal dynamics. In fact, all biological senses, (visual, hearing, tactile, etc.) process signals coming from different parts distributed in space and also show a complex time evolution. As an example, mammalian retina performs a parallel representation of the visual world embodied into layers, each of which r- resents a particular detail of the scene. These results clearly state that visual perception starts at the level of the retina, and is not related uniquely to the higher brain centres. Although vision remains the most useful sense guiding usual actions, the other senses, ?rst of all hearing but also touch, become essential particularly in cluttered conditions, where visual percepts are somehow obscured by environment conditions. Ef?cient use of hearing can be learnt from acoustic perception in animals/insects, like crickets, that use this ancient sense more than all the others, to perform a vital function, like mating.
Path following in combination with boundary value problem solvers has emerged as a continuing and strong influence in the development of dynamical systems theory and its application. It is widely acknowledged that the software package AUTO - developed by Eusebius J. Doedel about thirty years ago and further expanded and developed ever since - plays a central role in the brief history of numerical continuation. This book has been compiled on the occasion of Sebius Doedel's 60th birthday. Bringing together for the first time a large amount of material in a single, accessible source, it is hoped that the book will become the natural entry point for researchers in diverse disciplines who wish to...
Obstinate Star is a history of Puerto Rico’s independence struggle against Spanish and U.S. colonialism. From the time of the Napoleonic Wars, it traces the movement’s currents, within and beyond the island, linking them to ongoing social conflicts and international trends and conjunctures. Beginning with the radical democratic fight against Spanish control, it moves on to the early reactions to U.S. rule, the role of Nationalism, Communism and New Deal currents during the Great Depression and the Second World War, the rise of new forces in the wake of the Cuban revolution and recent struggles in the epoch of capitalist globalisation.
