Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.

A war is always a moral event. However, the most destructive war in human history has not received much moral scrutiny. The Good War That Wasn't--and Why It Matters examines the moral legacy of this war, especially for the United States. Drawing on the just war tradition and on moral values expressed in widely circulated statements of purpose for the war, the book asks: How did American participation in the war fit with just cause and just conduct criteria? Subsequently the book considers the impact of the war on American foreign policy in the years that followed. How did American actions cohere (or not) with the stated purposes for the war, especially self-determination for the peoples of the world and disarmament? Finally, the book looks at the witness of war opponents. Values expressed by war advocates were not actually furthered by the war. However, many war opponents did inspire efforts that effectively worked toward the goals of disarmament and self-determination. The Good War That Wasn't--and Why It Matters develops its arguments in pragmatic terms. It focuses on moral reasoning in a commonsense way in its challenge to widely held assumptions about World War II.
Succinct, highly readable and thought provoking, this important new text is designed to raise awareness of the potential economic impact of companion animals in the UK. It discusses the potential benefits and costs of companion animals to the economy and highlights the need for this matter to be thoroughly researched, given the potential scale of impact and the potential costs of ignoring this matter. Inspired by the seminal Council for Science and Society (CSS) Report, Companion Animals in Society (1988), this work updates and extends its evaluation of the economic impact of companion animals on society and lays a benchmark for future development. This pivotal new book is important for policy makers at national and international levels and all those involved in animal welfare.

An inspiring account of teachers in ordinary circumstances doing extraordinary things, showing us how to transform education What School Could Be offers an inspiring vision of what our teachers and students can accomplish if trusted with the challenge of developing the skills and ways of thinking needed to thrive in a world of dizzying technological change. Innovation expert Ted Dintersmith took an unprecedented trip across America, visiting all fifty states in a single school year. He originally set out to raise awareness about the urgent need to reimagine education to prepare students for a world marked by innovation--but America's teachers one-upped him. All across the country, he met teachers in ordinary settings doing extraordinary things, creating innovative classrooms where children learn deeply and joyously as they gain purpose, agency, essential skillsets and mindsets, and real knowledge. Together, these new ways of teaching and learning offer a vision of what school could be—and a model for transforming schools throughout the United States and beyond. Better yet, teachers and parents don't have to wait for the revolution to come from above. They can readily implement small changes that can make a big difference. America's clock is ticking. Our archaic model of education trains our kids for a world that no longer exists, and accelerating advances in technology are eliminating millions of jobs. But the trailblazing of many American educators gives us reasons for hope. Capturing bold ideas from teachers and classrooms across America, What School Could Be provides a realistic and profoundly optimistic roadmap for creating cultures of innovation and real learning in all our schools.
EJ 'Ted' Cutting was not only Aston Martin's most successful Chief Race Car Design Engineer, but was also an innovator with influential force on the worldwide automotive industry. Originating from a limited edition hardback version, this eBook was produced in celebration of the 60th anniversary of Aston Martin winning the World Sports Car Championship for Britain with the all-conquering DBR1 designed, engineered and created by Ted himself. Rather than a traditional biography of his life, Ted wanted his book to be rather less scripted and informal; it was therefore initially adapted from a number of recorded conversations between himself and Aston Martin Heritage Trust members Stuart Bailey and Brian Joscelyne - the title being an obvious choice considering this! In addition to the in-depth telling of a legendary period in British motorsport by a man at the centre of it all, the book also sees Ted clarify a number of details which have in the past been incorrectly reported. Unusually it also contains all his published documents and access to a 90 minute video of his unique lecture on 'Racing Astons' to further endorse his story. Although the original hardback edition of this book was produced only in a limited run, Ted's wish was to make the complete book available to a much wider audience, now possible through the internet; as an engineer always working at the cutting edge of technology, he would appreciate the benefits of information sharing in the digital age. As well as being of interest to fans of Aston Martin and of motorsports in general, the book is a compelling read for any student of automotive design and engineering; after all, progress is about standing on the shoulders of giants - and in the field of race car design, few individuals ever reach the colossal heights achieved by Ted Cutting.
The author seeks to clarify early Quaker views and explain how Friends came to differ so significantly in their beliefs from other English Protestants. By examining the Baptist-Quaker relationship in particular, he is able both to identify a primary link between the two and, and the same time, discover explanations for some of their dramatic differences. He draws on scores of previously unused tracts and manuscripts produced by the Baptist-Quaker disputes - materials which, in setting forth accusations, clarifications, and rebuttals, shed new light on the beliefs of the antagonists.

Viewed by some as symbols of progress and by others as inherently flawed, large dams remain one of the most contentious development issues on Earth. Building on the work of the now defunct World Commission on Dams, Thayer Scudder wades into the debate with unprecedented authority. Employing the Commission's Seven Strategic priorities, Scudder charts the 'middle way' forward by examining the impacts of large dams on ecosystems, societies and political economies. He also analyses the structure of the decision-making process for water resource development and tackles the highly contentious issue of dam-induced resettlement, illuminated by a statistical analysis of 50 cases.

More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP.
Voice over Internet Protocol is gaining a lot of attention these days. Both practical and fun, this text provides technology enthusiasts and voice professionals with dozens of hands-on projects for building a VoIP network, including a softPBX.
