Book Description
Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

Book Description
This volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X-15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it addresses the re-entry problem, which came to the forefront during the mid-1950s, showing how work in this area supported the manned space program and contributed to the development of the orbital shuttle. Subsequent chapters explore the fading of scramjet studies and the rise of the National Aerospace Plane (NASP) program of 1985–95, which sought to lay groundwork for single-stage vehicles. The program's ultimate shortcomings — in terms of aerodynamics, propulsion, and materials — are discussed, and the book concludes with a look at hypersonics in the post-NASP era, including the development of the X-33 and X-34 launch vehicles, further uses for scramjets, and advances in fluid mechanics. Clearly, ongoing research in hypersonics has yet to reach its full potential, and readers with an interest in aeronautics and astronautics will find this book a fascinating exploration of the field's history and future.

Book Description
This book combines practical guidance and theoretical background for analysts using empirical techniques in competition and antitrust investigations. Peter Davis and Eliana Garcés show how to integrate empirical methods, economic theory, and broad evidence about industry in order to provide high-quality, robust empirical work that is tailored to the nature and quality of data available and that can withstand expert and judicial scrutiny. Davis and Garcés describe the toolbox of empirical techniques currently available, explain how to establish the weight of pieces of empirical work, and make some new theoretical contributions. The book consistently evaluates empirical techniques in light of the challenge faced by competition analysts and academics--to provide evidence that can stand up to the review of experts and judges. The book's integrated approach will help analysts clarify the assumptions underlying pieces of empirical work, evaluate those assumptions in light of industry knowledge, and guide future work aimed at understanding whether the assumptions are valid. Throughout, Davis and Garcés work to expand the common ground between practitioners and academics.

Book Description
The Economic and Fiscal Consequences of Immigration finds that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. This report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. More than 40 million people living in the United States were born in other countries, and almost an equal number have at least one foreign-born parent. Together, the first generation (foreign-born) and second generation (children of the foreign-born) comprise almost one in four Americans. It comes as little surprise, then, that many U.S. residents view immigration as a major policy issue facing the nation. Not only does immigration affect the environment in which everyone lives, learns, and works, but it also interacts with nearly every policy area of concern, from jobs and the economy, education, and health care, to federal, state, and local government budgets. The changing patterns of immigration and the evolving consequences for American society, institutions, and the economy continue to fuel public policy debate that plays out at the national, state, and local levels. The Economic and Fiscal Consequences of Immigration assesses the impact of dynamic immigration processes on economic and fiscal outcomes for the United States, a major destination of world population movements. This report will be a fundamental resource for policy makers and law makers at the federal, state, and local levels but extends to the general public, nongovernmental organizations, the business community, educational institutions, and the research community.

Book Description
The book that is providing a storm of controversy, from ‘Israel’s bravest historian’ (John Pilger) Renowned Israeli historian, Ilan Pappe's groundbreaking work on the formation of the State of Israel. 'Along with the late Edward Said, Ilan Pappe is the most eloquent writer of Palestinian history.' NEW STATESMAN Between 1947 and 1949, over 400 Palestinian villages were deliberately destroyed, civilians were massacred and around a million men, women, and children were expelled from their homes at gunpoint. Denied for almost six decades, had it happened today it could only have been called 'ethnic cleansing'. Decisively debunking the myth that the Palestinian population left of their own accord in the course of this war, Ilan Pappe offers impressive archival evidence to demonstrate that, from its very inception, a central plank in Israel’s founding ideology was the forcible removal of the indigenous population. Indispensable for anyone interested in the current crisis in the Middle East. *** 'Ilan Pappe is Israel's bravest, most principled, most incisive historian.' JOHN PILGER 'Pappe has opened up an important new line of inquiry into the vast and fateful subject of the Palestinian refugees. His book is rewarding in other ways. It has at times an elegiac, even sentimental, character, recalling the lost, obliterated life of the Palestinian Arabs and imagining or regretting what Pappe believes could have been a better land of Palestine.' TIMES LITERARY SUPPLEMENT 'A major intervention in an argument that will, and must, continue. There's no hope of lasting Middle East peace while the ghosts of 1948 still walk.' INDEPENDENT

Book Description
World Development Indicators 2016 provides a compilation of relevant, high-quality, and internationally comparable statistics about global development and the fight against poverty. It is intended to help policymakers, students, analysts, professors, program managers, and citizens find and use data related to all aspects of development, including those that help monitor progress toward the World Bank Group’s two goals of ending poverty and promoting shared prosperity. Six themes are used to organize indicators—world view, people, environment, economy, states and markets, and global links. WDI 2016 includes: •A selection of the most popular indicators across 214 economies and 14 country groups organized into six WDI themes •A new section on the Sustainable Development Goals (SDGs) has replaced the one on Millennium Development Goals (MDGs). •The SDG section covers all 17 goals, and important targets to achieve these goals. Each goal has been presented in a maximum 2-page spread with selected indicators to explain the targets. •Each of the remaining sections includes an introduction, a map, a table of the most relevant and popular indicators for that theme together with a discussion of indicator compilation methodology. •A user guide describing resources available online and on mobile apps. Download the WDI DataFinder Mobile App and other Data Apps at data.worldbank.org/apps. WDI DataFinder is a mobile app for browsing the current WDI database on smartphones and tablets, using iOS and Android, available in four languages: English, French, Spanish, and Chinese. Use the app to: •Browse data using the structure of the WDI •Visually compare countries and indicators •Create, edit, and save customized tables, charts, and maps •Share what you create on Twitter, Facebook, and via email
