Book excerpt: En este libro se describen metodologías desarrolladas por los autores para la identificación de parámetros de líneas de transmisión y transformadores en un sistema de potencia eléctrica, y se presentan las técnicas basadas en estimación de estado para obtener valores confiables de los parámetros, empleando sistemas de mediciones fasoriales sincronizadas y mediciones clásicas de flujos de potencia. Los errores en los valores de los parámetros pueden conducir al aumento en la probabilidad de fallas catastróficas del sistema de energía eléctrica o a incrementar su costo de operación. Hasta la fecha, no se disponía de una metodología para estimar, en forma adecuada, todos los parámetros de líneas de transmisión y transformadores a partir de datos de operación. La obra puede ser de utilidad para estudiantes, investigadores e ingenieros interesados en la operación de sistemas de potencia eléctrica, estimación de estado, estimación de parámetros o en unidades de medición fasorial.

Book excerpt: This publication provides an overview of the common and unique sustainability elements of Indigenous Peoples' food systems, in terms of natural resource management, access to the market, diet diversity, indigenous peoples’ governance systems, and links to traditional knowledge and indigenous languages. While enhancing the learning on Indigenous Peoples food systems, it will raise awareness on the need to enhance the protection of Indigenous Peoples' food systems as a source of livelihood for the 476 million indigenous inhabitants in the world, while contributing to the Zero Hunger Goal. In addition, the UN Decade of Action on Nutrition (2016-2025) and the UN Food Systems Summit call on the enhancement of sustainable food systems and on the importance of diversifying diets with nutritious foods, while broadening the existing food base and preserving biodiversity. This is a feature characteristic of Indigenous Peoples' food systems since hundreds of years, which can provide answers to the current debate on sustainable food systems and resilience.

Book excerpt: The book is based on the exchange of professional experiences which featured in an IUCN CEC workshop in August 2002. Practitioners from around the world shared their models of good practice and explored the challenges involved in engaging people in sustainability. The difficulties facing practitioners vary between country and context but some challenges are universal: A lack of clarity in communicating what is meant by sustainable development; An ambition to educate everyone to bring about a global citizenship; Social, organisational or institutional factors constrain change to sustainable development, yet there is an emphasis on formal education, and community educators do not receive the same support; A lack of balance in addressing the integration of environmental, social and economic dimensions leading to an interpretation that ESD is mainly about environment and conservation issues; New learning (rather than teaching) approaches are called for to promote more debate in society. Yet, few are trained or experienced in these new approaches. Practitioners need support to explore new ways of promoting learning. [Foreword, ed].

Book excerpt: In 2011, political protests sprang up across the world. In the Middle East, Europe, Latin America, the United States unlikely people sparked or led massive protest campaigns from the Arab Spring to Occupy Wall Street. These protests were made up of educated and precariously employed young people who challenged the legitimacy of their political leaders, exposed a failure of representation, and expressed their dissatisfaction with their place in the aftermath of financial and economic crisis. This book interrogates what impacts--if any--this global protest cycle had on politics and policy and shows the sometimes unintended ways it continues to influence contemporary political dynamics throughout the world. Proposing a new framework of analysis that calls attention to the content and claims of protests, their global connections, and the responsiveness of political institutions to protest demands, this is one of the few books that not only asks how protest movements are formed but also provides an in-depth examination of what protest movements can accomplish. With contributions examining the political consequences of protest, the roles of social media and the internet in protest organization, left- and right-wing movements in the United States, Chile's student movements, the Arab Uprisings, and much more this collection is essential reading for all those interested in the power of protest to shape our world.

This book was released on 2015-08-20 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Confronting Climate Uncertainty in Water Resources Planning and Project Design describes an approach to facing two fundamental and unavoidable issues brought about by climate change uncertainty in water resources planning and project design. The first is a risk assessment problem. The second relates to risk management. This book provides background on the risks relevant in water systems planning, the different approaches to scenario definition in water system planning, and an introduction to the decision-scaling methodology upon which the decision tree is based. The decision tree is described as a scientifically defensible, repeatable, direct and clear method for demonstrating the robustness of a project to climate change. While applicable to all water resources projects, it allocates effort to projects in a way that is consistent with their potential sensitivity to climate risk. The process was designed to be hierarchical, with different stages or phases of analysis triggered based on the findings of the previous phase. An application example is provided followed by a descriptions of some of the tools available for decision making under uncertainty and methods available for climate risk management. The tool was designed for the World Bank but can be applicable in other scenarios where similar challenges arise.

Available in PDF, EPUB and Kindle. Book excerpt: "Rambo took the barrios by storm: Spanish videotapes of the movie were widely available, and nearly all the boys and young men had seen it, usually on the VCRs of their family's more affluent friends. . . . As one young Sandinista commented, 'Rambo is like the Nicaraguan soldier. He's a superman. And if the United States invades, we'll cut the marines down like Rambo did.' And then he mimicked Rambo's famous war howl and mimed his arc of machine gun fire. We both laughed."—from the book There is a Nicaragua that Americans have rarely seen or heard about, a nation of jarring political paradoxes and staggering social and cultural flux. In this Nicaragua, the culture of machismo still governs most relationships, insidious racism belies official declarations of ethnic harmony, sexual relationships between men differ starkly from American conceptions of homosexuality, and fascination with all things American is rampant. Roger Lancaster reveals the enduring character of Nicaraguan society as he records the experiences of three families and their community through times of war, hyperinflation, dire shortages, and political turmoil. Life is hard for the inhabitants of working class barrios like Doña Flora, who expects little from men and who has reared her four children with the help of a constant female companion; and life is hard for Miguel, undersized and vulnerable, stigmatized as a cochón—a "faggot"—until he learned to fight back against his brutalizers. Through candid discussions with young and old Nicaraguans, men and women, Lancaster constructs an account of the successes and failures of the 1979 Sandinista Revolution, documenting the effects of war and embargo on the cultural and economic fabric of Nicaraguan society. He tracks the break up of families, surveys informal networks that allow female-headed households to survive, explores the gradual transformation of the culture of machismo, and reveals a world where heroic efforts have been stymied and the best hopes deferred. This vast chronicle is sustained by a rich theoretical interpretation of the meanings of ideology, power, and the family in a revolutionary setting. Played out against a backdrop of political travail and social dislocation, this work is a story of survival and resistance but also of humor and happiness. Roger Lancaster shows us that life is hard, but then too, life goes on.
