Roving vigilantes, fear-mongering politicians, hysterical pundits, and the looming shadow of a seven hundred-mile-long fence: the US–Mexican border is one of the most complex and dynamic areas on the planet today. Hyperborder provides the most nuanced portrait yet of this dynamic region. Author Fernando Romero presents a multidisciplinary perspective informed by interviews with numerous academics, researchers, and organizations. Provocatively designed in the style of other kinetic large-scale studies like Rem Koolhaas's Content and Bruce Mau’s Massive Change, Hyperborder is an exhaustively researched report from the front lines of the border debate.
Combining approaches and insights from cultural, social and military history this study traces the evolution and decline of the Spanish officer corps and general staff during the Eighty Years War in connection with contemporary trends such as modernization and aristocratization.
This book outlines the transitions between cultured and natural land cover/vegetation types and their implications in the search for alternatives to reverse the trend of anthropogenic environmental degradation. It also elaborates on the proposed “standardized hierarchical Mexican vegetation classification system” and geobotanical mapping, a critical transversal environmental issue. The first chapter consists of an historical review of the common approaches to the study of vegetation both in Mexico and in other regions of the world. The second chapter concisely analyzes the existing schools of thought that have led to the development of vegetation classification systems based on physiognomic, structural and floristic approaches. The focal point of the book is the “standardized hierarchical Mexican vegetation classification system” (SECLAVEMEX – “Sistema jerárquico estandarizado para la clasificación de la vegetación de México”). Chapter 3 describes the system’s organizational levels along with the criteria defining them and the nomenclatural basis for the denomination of each type of vegetation. It also includes a series of tables explaining and precisely defining the meaning of each concept, criterion, character and element used to help readers successfully identify the type of vegetation in a determined area. The fourth chapter highlights SECLAVEMEX's inclusive character as evidenced through its compatibility with other systems currently used around the globe. Three concepts are critically reviewed: land cover, land use and vegetation. These are often the study subject of the contrasting disciplines geography, agronomy and ecology, which all rely upon plant species assemblages. As such, the final chapter focuses on a critical transversal environmental issue – geobotanical mapping. Geobotanical mapping offers a baseline for land cover/use planning and provides critical information on ecological, economic and cultural attributes, which can be used as a basis for environmental-policy decisions. The proposed SECLAVEMEX was applied to Mexico as an example of land cover, land use and vegetation patterns intermingling as the result of a long human influence. SECLAVEMEX, however, can be adapted and hopefully adopted globally as a baseline for consistently comparing geobotanical patterns and their transitions.
Central America, Panama, and the Dominican Republic coped well with the global financial crisis of 2008-09. The impact was generally less severe and shorter lived than in previous episodes, the balance of payments adjustment was orderly, and the stability of the financial system was not compromised. This resilience can be attributed to a large extent to the strengthening of the fiscal frameworks, monetary management, and financial reforms conducted in the years preceding the global crisis. Nevertheless, the region faces considerable challenges for the period ahead, including the need to raise medium term growth above historical levels and protect macroeconomic and financial stability. This book argues that meeting these challenges will have to come from within, in light of the anticipated modest demand growth from trade partners. Raising growth in the region will depend on the adoption of structural reforms that generate substantial productivity gains. Rebuilding fiscal space and securing debt sustainability will hinge on efforts to increase tax revenue and reorienting spending to social and investment priorities. In the non-officially dollarized economies, it will also be essential to strengthen the monetary policy frameworks to keep inflation low and increase exchange rate flexibility, and improve financial regulation and supervision.
In Elusive Unity, Armstrong-Fumero examines early twentieth-century peasant politics and twenty-first-century indigenous politics in the rural Oriente region of Yucatán. The rural inhabitants of this region have had some of their most important dealings with their nation’s government as self-identified “peasants” and “Maya.” Using ethnography, oral history, and archival research, Armstrong-Fumero shows how the same body of narrative tropes has defined the local experience of twentieth-century agrarianism and twenty-first-century multiculturalism. Through these recycled narratives, contemporary multicultural politics have also inherited some ambiguities that were built into its agrarian predecessor. Specifically, local experiences of peasant and indigenous politics are shaped by tensions between the vernacular language of identity and the intense factionalism that often defines the social organization of rural communities. This significant contribution will be of interest to historians, anthropologists, and political scientists studying Latin America and the Maya.
Twentieth Century Guerrilla Movements in Latin America: A Primary Source History collects political writings on human rights, social injustice, class struggle, anti-imperialism, national liberation, and many other topics penned by urban and rural guerrilla movements. In the second half of the twentieth century, Latin America experienced a mass wave of armed revolutionary movements determined to overthrow oppressive regimes and eliminate economic exploitation and social injustices. After years of civil resistance, and having exhausted all peaceful avenues, thousands of working-class people, peasants, professions, intellectuals, clergymen, students, and teachers formed dozens of guerrilla movements. Fernando Herrera Calderón presents important political writings, some translated into English here for the first time, that serve to counteract the government propaganda that often overshadowed the intellectual side of revolutionary endeavors. These texts come from Latin American countries such as Argentina, Bolivia, Colombia, Mexico, Nicaragua, and many more. The book will be indispensable to anyone teaching or studying revolutions in modern Latin American history.

The domain of catalytic hydrogenation continues to grow fast, reflecting the wide range of chemical applications that can be enhanced by the easy use of molecular hydrogen. The advances in characterization techniques and their application have improved our understanding of the catalytic processes and mechanisms occurring in both homogeneous and heterogeneous catalysis. The aim of this volume, although not exhaustive, is to provide a general overview of new progress of the hydrogenation reactions. This volume comprises a series of various contributions, as reviews or original articles, treating heterogeneously and homogeneously catalyzed hydrogenation reactions. It is composed of three parts: hydrogenation reactions in fine organic chemistry, hydrogenation reactions in environmental chemistry and renewable energy, and special topics in hydrogenation.
A temporary move to Toronto in the winter of 2000, a twisted ankle, an empty house -- all inspired Moure as she read Alberto Caeiro/Fernando Pessoa's classic long poem O Guardador de Rebanhos. For fun, she started to translate, altering tones and vocabularies. From the Portuguese countryside and roaming sheep of 1914, a 21st century Toronto emerged, its neighbourhoods still echoing the 1950s, their dips and hollows, hordes of wild cats, paved creeks. Her poem became a translation, a transcreation, the jubilant and irrepressible vigil of a fervent person. "Suddenly," says Moure impishly, "I had found my master." Caeiro's sheep were his thoughts and his thoughts, he claimed, were all sensations. Moure's sheep are stray cats and from her place in Caeiro's poetry, she creates a woman alive in an urban world where the rural has not vanished, where the archaic suffuses us even when we do not beckon it, and yet the present tense floods us fully.
With its astounding hardcover reviews Richard Zenith's new complete translation of THE BOOK OF DISQUIET has now taken on a similar iconic status to ULYSSES, THE TRIAL or IN SEARCH OF LOST TIME as one of the greatest but also strangest modernist texts. An assembly of sometimes linked fragments, it is a mesmerising, haunting 'novel' without parallel in any other culture.
For the first time—and in the best translation ever—the complete Book of Disquiet, a masterpiece beyond comparison The Book of Disquiet is the Portuguese modernist master Fernando Pessoa’s greatest literary achievement. An “autobiography” or “diary” containing exquisite melancholy observations, aphorisms, and ruminations, this classic work grapples with all the eternal questions. Now, for the first time the texts are presented chronologically, in a complete English edition by master translator Margaret Jull Costa. Most of the texts in The Book of Disquiet are written under the semi-heteronym Bernardo Soares, an assistant bookkeeper. This existential masterpiece was first published in Portuguese in 1982, forty-seven years after Pessoa’s death. A monumental literary event, this exciting, new, complete edition spans Fernando Pessoa’s entire writing life.
