Book Description
When Joseph Collier left Scotland bound for Central City, Colorado in 1871, it was unclear whether the young immigrant would make much of a name for himself. However, through hard work and perseverance, Collier developed a reputation as one of the state's preeminent pioneer photographers. Now, over a century later, Grant Collier has literally followed in the footsteps of his great-great-grandfather. Grant has traveled across Colorado taking photographs from precisely the same spots where Joseph Collier captured his images. These photographs are presented in the often imitated but never duplicated "Colorado: Yesterday & Today."

Book Description
Our world is changing at an accelerating rate. The global human population has grown from 6.1 billion to 7.1 billion in the last 15 years and is projected to reach 11.2 billion by the end of the century. The distribution of humans across the globe has also shifted, with more than 50 percent of the global population now living in urban areas, compared to 29 percent in 1950. Along with these trends, increasing energy demands, expanding industrial activities, and intensification of agricultural activities worldwide have in turn led to changes in emissions that have altered the composition of the atmosphere. These changes have led to major challenges for society, including deleterious impacts on climate, human and ecosystem health. Climate change is one of the greatest environmental challenges facing society today. Air pollution is a major threat to human health, as one out of eight deaths globally is caused by air pollution. And, future food production and global food security are vulnerable to both global change and air pollution. Atmospheric chemistry research is a key part of understanding and responding to these challenges. The Future of Atmospheric Chemistry Research: Remembering Yesterday, Understanding Today, Anticipating Tomorrow summarizes the rationale and need for supporting a comprehensive U.S. research program in atmospheric chemistry; comments on the broad trends in laboratory, field, satellite, and modeling studies of atmospheric chemistry; determines the priority areas of research for advancing the basic science of atmospheric chemistry; and identifies the highest priority needs for improvements in the research infrastructure to address those priority research topics. This report describes the scientific advances over the past decade in six core areas of atmospheric chemistry: emissions, chemical transformation, oxidants, atmospheric dynamics and circulation, aerosol particles and clouds, and biogeochemical cycles and deposition. This material was developed for the NSF's Atmospheric Chemistry Program; however, the findings will be of interest to other agencies and programs that support atmospheric chemistry research.

Book Description
In 1982 the Kanazawa Institute of Technology Library Center inaugurated an international seminar program and invited noted scholars from all over the world to participate. This volume brings together distinguished papers presented over the past ten years. Thirty-three papers organized into five broad subject areas--research libraries in the Twenty-first century; information access in the new era; new technology, new media, and library buildings; library education; preservation of research materials; the technological university library; and managing knowledge in the twenty-first century--deal with topics considered to be of greatest interest to those involved with the future evolution of research libraries.

Book Description
Yesterday, Today, and Tomorrow provides a compelling analysis of the forces and choices that have shaped the trend toward the resegregation of public schools. By assembling a wide range of contributors—historians, sociologists, economists, and education scholars—the editors provide a comprehensive view of a community’s experience with desegregation and economic development. Here we see resegregation through the lens of Charlotte, North Carolina, once a national model of successful desegregation, and home of the landmark Swann desegregation case, which gave rise to school busing. This book recounts the last forty years of Charlotte’s desegregation and resegregation, putting education reform in political and economic context. Within a decade of the Swanncase, the district had developed one of the nation’s most successful desegregation plans, measured by racial balance and improved academic outcomes for both black and white students. However, beginning in the 1990s, this plan was gradually dismantled. Today, the level of resegregation in Charlotte has almost returned to what it was prior to 1971. At the core of Charlotte’s story is the relationship between social structure and human agency, with an emphasis on how yesterday’s decisions and actions define today’s choices.

Book Description
The High Plains region was once called the Great American Desert and thought to be, in the words of explorer Stephen Long, “wholly unfit for cultivation.” Now we know that beneath the surface, unbeknownst to the explorers and early settlers, lies the Ogallala aquifer, an underground formation that stretches for 800 miles from the Texas panhandle to South Dakota. It holds more water than Lake Huron. Indeed, the Ogallala has been referred to as the sixth Great Lake. It is the water pumped for irrigation from the Ogallala that has enabled a naturally dry region to produce up to 40 percent of America’s beef and 20 to 25 percent of its food and fiber, an output worth about $20 billion. In the forty years since the invention of center pivot irrigation, the High Plains aquifer system has been depleted at an astonishing rate. In 1978 the volume of water pumped from the aquifer exceeded the annual flow of the Colorado River. In Texas, water levels are down 200 feet in some areas. In Kansas, 700 miles of rivers that once flowed year round no longer flow at all. In short, the High Plains may be becoming the desert it was once thought to be. Is it too late to solve the problem? Geographers David Kromm and Stephen White assembled nine of the most knowledgeable scholars and water professionals in the Great Plains to help answer that question. The result is a collection of essays that insightfully examine the dilemmas of groundwater use. From a variety of perspectives they address both the technical problems and the politics of water management to provide a badly needed analysis of the implications of large-scale irrigation. They have included three case studies: the Nebraska Sand Hills, Northwestern Kansas, and West Texas. Kromm and White provide an introduction and conclusion to the volume.
