Spatial statistics is one of the most rapidly growing areas of statistics, rife with fascinating research opportunities. Yet many statisticians are unaware of those opportunities, and most students in the United States are never exposed to any course work in spatial statistics. Written to be accessible to the nonspecialist, this volume surveys the applications of spatial statistics to a wide range of areas, including image analysis, geosciences, physical chemistry, and ecology. The book describes the contributions of the mathematical sciences, summarizes the current state of knowledge, and identifies directions for research.

The information age is taking its toll on traditional office management techniques. According to Infosystems, "If you're cautious of 'experts' who claim to have all the answers, then you'll find comfort in the theme of 'unleashed creativity' that recurs throughout the 20 essays presented in this book....Organizations will have to devise a strategy for understanding how [a microcomputer's] performance can be monitored. Regardless of what may happen, this book provides managers with appropriate ammunition."

This volume documents the continuing growth of concentrated poverty in central cities of the United States and examines what is known about its causes and effects. With careful analyses of policy implications and alternative solutions to the problem, it presents: A statistical picture of people who live in areas of concentrated poverty. An analysis of 80 persistently poor inner-city neighborhoods over a 10-year period. Study results on the effects of growing up in a "bad" neighborhood. An evaluation of how the suburbanization of jobs has affected opportunities for inner-city blacks. A detailed examination of federal policies and programs on poverty. Inner-City Poverty in the United States will be a valuable tool for policymakers, program administrators, researchers studying urban poverty issues, faculty, and students.

In developing countries, traditional fishermen are important food contributors, yet technological information and development assistance to third-world nations often focuses on agriculture and industrial fishing, without addressing the needs of independent, small-scale fishermen. This book explores technological considerations of small-scale, primitive fishing technologies, and describes innovative, relatively inexpensive methods and tools that have already been successfully applied in developing countries. It offers practical information about all aspects of small-scale fishing, including boat design and construction, fishing methods and gear, artificial reef construction and fish aggregating devices, techniques for coastal mariculture, and simple methods for processing and preserving fish once they are caught. Fisheries Technologies for Developing Countries is illustrated throughout with photographs of the devices and construction methods described in the text.

This book presents a carefully developed monitoring system to track the progress of mathematics and science education, particularly the effects of ongoing efforts to improve students' scientific knowledge and mathematics competency. It describes an improved series of indicators to assess student learning, curriculum quality, teaching effectiveness, student behavior, and financial and leadership support for mathematics and science education. Of special interest is a critical review of current testing methods and their use in probing higher-order skills and evaluating educational quality.

In this provocative volume, distinguished authorities on urban policy expose the myths surrounding today's "infrastructure crisis" in urban public works. Five in-depth papers examine the evolution of the public works system, the limitations of urban needs studies, the financing of public works projects, the impact of politics, and how technology is affecting the types of infrastructures needed for tomorrow's cities.

When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"?trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

Many feedstuffs and forages do not provide the dietary vitamins necessary for optimum growth and development, making supplementation necessary. This volume offers a practical, well-organized guide to safe levels of vitamin supplementation in all major domestic species, including poultry, cattle, sheep, and fishes. Fourteen essential vitamins are discussed with information on requirements in various species, deficiency symptoms, metabolism, indications of hypervitaminosis, and safe dosages.

The most recent volume in the Drinking Water and Health series contains the results of a two-part study on the toxicity of drinking water contaminants. The first part examines current practices in risk assessment, identifies new noncancerous toxic responses to chemicals found in drinking water, and discusses the use of pharmacokinetic data to estimate the delivered dose and response. The second part of the book provides risk assessments for 14 specific compounds, 9 presented here for the first time.

After v. 1, each volume's t.p. names a different panel at the beginning of its author statement.

The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool? The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence. The book looks at: The theory of how the polygraph works and evidence about how deceptiveness--and other psychological conditions--affect the physiological responses that the polygraph measures. Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures. The actual use of the polygraph in the arena of national security, including its role in deterring threats to security. The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternatives--such as voice-stress analysis and brain measurement techniques.

The Small Business Innovation Research (SBIR) program is one of the largest examples of U.S. public-private partnerships. Founded in 1982, SBIR was designed to encourage small business to develop new processes and products and to provide quality research in support of the many missions of the U.S. government, including health, energy, the environment, and national defense. In response to a request from the U.S. Congress, the National Research Council assessed SBIR as administered by the five federal agencies that together make up 96 percent of program expenditures. This book, one of six in the series, reports on the SBIR program at the National Science Foundation. The study finds that the SBIR program is sound in concept and effective in practice, but that it can also be improved. Currently, the program is delivering results that meet most of the congressional objectives, including stimulating technological innovation, increasing private-sector commercialization of innovations, using small businesses to meet federal research and development needs, and fostering participation by minority and disadvantaged persons. The book suggests ways in which the program can improve operations, continue to increase private-sector commercialization, and improve participation by women and minorities.
