La violencia, como el arte, son elementos que siempre han existido y cuya definición siempre se ha hecho de diferentes maneras, ciertamente y en gran medida por la perspectiva desde dónde se observan, se viven o se reflexionan, y de cualquiera de esas formas se ha provocado de manera constante a crear un amplio contenido de conceptos, así como de formas para observarles, entenderles, asimilarles y hasta expresarles. También se puede apreciar una amplia gama de tonalidades e intensidades dependiendo desde dónde se refleje la luz o la sombra, tiene cuerpo, una estructura, se le puede colocar el rostro con la expresividad que se desee de acuerdo con lo evocado por cada uno, es más, puede tener u otorgarle vida a más de un rostro, si se le observa con cuidado.
Lead is a ubiquitous metal in the environment, and its adverse effects on human health are well documented. Lead interacts at multiple cellular sites and can alter protein function in part through binding to amino acid sulfhydryl and carboxyl groups on a wide variety of structural and functional proteins. In addition, lead mimics calcium and other divalent cations, and it induces the increased production of cytotoxic reactive oxygen species. Adverse effects associated with lead exposure can be observed in multiple body systems, including the nervous, cardiovascular, renal, hematologic, immunologic, and reproductive systems. Lead exposure is also known to induce adverse developmental effects ...
Workplace bullying is an area that has attracted significant press attention throughout the last decade. A variety of well publicized surveys have revealed that this is an issue endemic in working life in Britain; and, at a conservative estimate, over half the working population can expect to experience bullying at work (either directly by being bu
In Carrying the Word: The Concheros Dance in Mexico City, the first full length study of the Concheros dancers, Susanna Rostas explores the experience of this unique group, whose use of dance links rural religious practices with urban post-modern innovation in distinctive ways even within Mexican culture, which is rife with ritual dances. The Concheros blend Catholic and indigenous traditions in their performances, but are not governed by a predetermined set of beliefs; rather they are bound together by long standing interpersonal connections framed by the discipline of their tradition. The Concheros manifest their spirituality by means of the dance. Rostas traces how they construct their identity and beliefs, both individual and communal, by its means. The book offers new insights into the experience of dancing as a Conchero while also exploring their history, organization and practices. Carrying the Word provides a new way for audiences to understand the Conchero's dance tradition, and will be of interest to students and scholars of contemporary Mesoamerica. Those studying identity, religion, and tradition will find this social-anthropological work particularly enlightening.
A multidisciplinary investigation of contemporary Mexican cinema
Violence at work, ranging from bullying and mobbing, to threats by psychologically unstable co-workers, sexual harassment and homicide, is increasing worldwide and has reached epidemic levels in some countries. This updated and revised edition looks at the full range of aggressive acts, offers new information on their occurrence and identifies occupations and situations at particular risk. It is organised in three sections: understanding violence at work; responding to violence at work; future action.
It is accepted wisdom today that human beings have irrevocably damaged the natural world. Yet what if this narrative obscures a more hopeful truth? In Inheritors of the Earth, renowned ecologist and environmentalist Chris D. Thomas overturns the accepted story, revealing how nature is fighting back. Many animals and plants actually benefit from our presence, raising biological diversity in most parts of the world and increasing the rate at which new species are formed, perhaps to the highest level in Earth's history. From Costa Rican tropical forests to the thoroughly transformed British landscape, nature is coping surprisingly well in the human epoch. Chris Thomas takes us on a gripping rou...
This book, first published in 1933, examines the life and achievements of Henry Adams, the American historian and political journalist. It looks at his youth and early development of his ideas, and goes on to look at his time as a diplomat, historian and journalist – and his impact upon American political and intellectual life.
Organocatalysis has recently attracted enormous attention as green and sustainable catalysis. It was realized as a fundamental field providing wide families of catalysts for important organic transformations. It will certainly develop in the future. Given the diversity of accessible transformations, metal-catalyzed reactions have become major tools in organic synthesis that will undoubtedly continue to have an important impact in the future. Alternatively, over the last years, a metal-free approach such as organocatalysis has reached a level of faithfulness, allowing researchers to discover new catalytic systems based on engagement of new or early-prepared organic molecules as organocatalysts. Organocatalysis meets green chemistry principles, especially the reduction of toxicity and chemical accidents, the biodegradability, and the use of benign and friendlier reaction media and conditions.
