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
An argument that operational urban planning can be improved by the application of the tools of urban economics to the design of regulations and infrastructure. Urban planning is a craft learned through practice. Planners make rapid decisions that have an immediate impact on the ground—the width of streets, the minimum size of land parcels, the heights of buildings. The language they use to describe their objectives is qualitative—“sustainable,” “livable,” “resilient”—often with no link to measurable outcomes. Urban economics, on the other hand, is a quantitative science, based on theories, models, and empirical evidence largely developed in academic settings. In this book, the eminent urban planner Alain Bertaud argues that applying the theories of urban economics to the practice of urban planning would greatly improve both the productivity of cities and the welfare of urban citizens. Bertaud explains that markets provide the indispensable mechanism for cities’ development. He cites the experience of cities without markets for land or labor in pre-reform China and Russia; this “urban planners’ dream” created inefficiencies and waste. Drawing on five decades of urban planning experience in forty cities around the world, Bertaud links cities’ productivity to the size of their labor markets; argues that the design of infrastructure and markets can complement each other; examines the spatial distribution of land prices and densities; stresses the importance of mobility and affordability; and critiques the land use regulations in a number of cities that aim at redesigning existing cities instead of just trying to alleviate clear negative externalities. Bertaud concludes by describing the new role that joint teams of urban planners and economists could play to improve the way cities are managed.

Book Description
A photojournalist documents a young woman’s journey as joins a New Jersey convent to become a nun. The sudden revelation of a powerful religious calling was an entirely unexpected event in the life of a college student named Lauren. But when it became clear to her that she had a spiritual vocation, she made the exceptional decision to dedicate her life to God. Drawing upon many visits to the cloistered religious community of Dominican nuns in Summit, New Jersey, photographer Toni Greaves has created a luminous body of work that follows the transformative journey by which Lauren became Sister Maria Teresa of the Sacred Heart. These meditative photographs capture the radical joy of a life dedicated unequivocally to love. “Toni Greaves’s luminous images marry the quotidian with the divine in all sorts of ways: a young novice dribbles a basketball in full habit; a jar of Vick’s VapoRub nestles a bottle of holy water; a group portrait of all 19 sisters, whose ages range from 25 to 90, includes Sabina, the golden retriever, splayed flat on the floor.” —New York Times

Book Description
How can countries make sustainable gains in student learning at scale? This is a pressing question for Latin America and the Caribbean (LAC)--and the developing world more broadly--as countries seek to build human capital to drive sustainable growth. Significant progress in access has expanded coverage such that nearly all children in the region attend primary school, but many do not gain basic skills and drop out before completing secondary school, in part due to low-quality service delivery. The preponderance of evidence shows that it is learning--and not schooling in and of itself--that contributes to individual earnings, economic growth, and reduced inequality. For LAC in particular, low levels of human capital are a critical factor in explaining the region’s relatively weak growth performance over the last half century. The easily measurable inputs are well-known, and the end goal is relatively clear, but raising student achievement at scale remains a challenge. Why? Part of the answer lies in management--the managers, structures, and practices that guide how inputs into the education system are translated into outputs, and ultimately outcomes. While management is often mentioned as an important factor in education policy discussions, relatively little quantitative research has been done to define and measure it. And even less has been done to unpack how and how much management matters for education quality. This study presents new conceptual and empirical contributions that can be synthesized in four key messages: 1. Student learning is unlikely to improve at scale without better management. 2. Management quality can be measured and should be measured as a catalyst for improvement. 3. Management affects how well every level of an education system functions, from individual schools to central technical units, and how well they work together. 4. Several pathways to strengthening management are open to LAC countries now, with the potential for significant results. The study elaborates on each of these messages, synthesizing recent data and research and presenting the results of several new research initiatives from across the region.

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 sheds light on one of the most controversial issues of the decade. It identifies the economic gains and losses from immigration--for the nation, states, and local areas--and provides a foundation for public discussion and policymaking. Three key questions are explored: What is the influence of immigration on the overall economy, especially national and regional labor markets? What are the overall effects of immigration on federal, state, and local government budgets? What effects will immigration have on the future size and makeup of the nation's population over the next 50 years? The New Americans examines what immigrants gain by coming to the United States and what they contribute to the country, the skills of immigrants and those of native-born Americans, the experiences of immigrant women and other groups, and much more. It offers examples of how to measure the impact of immigration on government revenues and expenditures--estimating one year's fiscal impact in California, New Jersey, and the United States and projecting the long-run fiscal effects on government revenues and expenditures. Also included is background information on immigration policies and practices and data on where immigrants come from, what they do in America, and how they will change the nation's social fabric in the decades to come.

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.
