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.

2020 Canadian Association for Latin American and Caribbean Studies (CALACS) Book Prize In post-1968 Mexico a group of artists and feminist activists began to question how feminine bodies were visually constructed and politicized across media. Participation of women was increasing in the public sphere, and the exclusive emphasis on written culture was giving way to audio-visual communications. Motivated by a desire for self-representation both visually and in politics, female artists and activists transformed existing regimes of media and visuality. Women Made Visible by Gabriela Aceves Sepúlveda uses a transnational and interdisciplinary lens to analyze the fundamental and overlooked role played by artists and feminist activists in changing the ways female bodies were viewed and appropriated. Through their concern for self-representation (both visually and in formal politics), these women played a crucial role in transforming existing regimes of media and visuality--increasingly important intellectual spheres of action. Foregrounding the work of female artists and their performative and visual, rather than written, interventions in urban space in Mexico City, Aceves Sepúlveda demonstrates that these women feminized Mexico's mediascapes and shaped the debates over the female body, gender difference, and sexual violence during the last decades of the twentieth century. Weaving together the practices of activists, filmmakers, visual artists, videographers, and photographers, Women Made Visible questions the disciplinary boundaries that have historically undermined the practices of female artists and activists and locates the development of Mexican second-wave feminism as a meaningful actor in the contested political spaces of the era, both in Mexico City and internationally.

Incluye audio del autor. ¿Quiénes son los ninfoleptos? Antiguamente se les identificaba como personajes delirantes frente a las ninfas cuyas mentes veían emergiendo de una fuente. Sin embargo, ver visiones no era su único infortunio. La depresión y otras manías se consideraban su peor castigo. Hoy, mucho tiempo después se sabe que los ninfoleptos padecen bipolaridad, ese trastorno de la conducta que padecen importantes artistas de diversas disciplinas y que lo hizo ser considerado un don, más que un trastorno. Arte y enfermedad, vistos desde el ojo científico, es el tema que aborda Óscar Benassini en este ensayo en el que lo mismo nos sentiremos conmovidos frente al drama infantil de la poetisa Sylvia Plath que frente a las locuras adolescentes del rockero Kurt Cobain. La bipolaridad es un trastorno tan especial de la conducta y con tantas aristas, que algunos han planteado incluso la posibilidad de que antes que una enfermedad sea considerada un don, debido a la gran cantidad de artistas geniales que la han sufrido.

This concisely written book gives an elementary introduction to a classical area of mathematics—approximation theory—in a way that naturally leads to the modern field of wavelets. The exposition, driven by ideas rather than technical details and proofs, demonstrates the dynamic nature of mathematics and the influence of classical disciplines on many areas of modern mathematics and applications. Key features and topics: * Description of wavelets in words rather than mathematical symbols * Elementary introduction to approximation using polynomials (Weierstrass’ and Taylor’s theorems) * Introduction to infinite series, with emphasis on approximation-theoretic aspects * Introduction to Fourier analysis * Numerous classical, illustrative examples and constructions * Discussion of the role of wavelets in digital signal processing and data compression, such as the FBI’s use of wavelets to store fingerprints * Minimal prerequisites: elementary calculus * Exercises that may be used in undergraduate and graduate courses on infinite series and Fourier series Approximation Theory: From Taylor Polynomials to Wavelets will be an excellent textbook or self-study reference for students and instructors in pure and applied mathematics, mathematical physics, and engineering. Readers will find motivation and background material pointing toward advanced literature and research topics in pure and applied harmonic analysis and related areas.

"The first exhibition to offer a critical assessment of the artistic experimentation that took place in Mexico during the last three decades of the twentieth century. The exhibition carefully analyzes the origins and emergence of techniques, strategies, andmodes of operation at a particularly significant moment of Mexican history, beginning with the 1968 Student Movement, until the Zapatista upraising in the State of Chiapas. Theshow includes work by a wide range of artists, including Francis Alys, Vicente Rojo, Jimmie Durham, Helen Escobedo, Julio Galán, Felipe Ehrenberg, José Bedia,Guillermo Gómez-Peña, Francisco Toledo, Carlos Amorales, Melanie Smith, and Alejandro Jodorowsky, among many others. The edition is illustrated with 612 full-colorplates of the art produced during these last three decades of the twentieth century reflect the social, political and technical developments in Mexico and ranged from painting andphotography to poster design, installation, performance, experimental theatre, super-8 cinema, video, music, poetry and popular culture like the films and ephemeral actionsof 'Panic' by Alejandro Jodorowsky, Pedro Friedeberg's pop art, the conceptual art, infrarrealists and urban independent photography, artists books, the development ofcontemporary political photography, the participation of Mexican artists in Fluxus in the seventies and the contribution of Ulises Carrión to the international artist book movement and popular rock music, the pictorial battles of the eighties and the emergence of a variant of neo-conceptual art in 1990. The exhibition is curated by Olivier Debroise, Pilar García de Germenos, Cuauhtémoc Medina, Álvaro Vázquez Mantecón"--Provided by vendor.
