As we approach the 21st century, there is a discernable shift in policing, from an incident-driven perspective to a proactive problem solving stance often described as "community policing." In this volume a panel of 21 psychologists examine the changing directions in policing and how such changes impact on psychological service delivery and operational support to law enforcement agencies. The book describes existing and emerging means of providing psychological support to the law enforcement community in response to police needs to accommodate new technology, community-oriented problem solving technology, crime prevention, and sensitivity to community social changes. Senior psychologists who are sworn officers, federal agents and civilian employees of federal, state and local law enforcement agencies comprise the team of chapter authors. Their perspectives encompass their collective experience "in the trenches" and in law enforcement management and administrative support roles. They discuss traditional applications of psychology to police selection, training and promotion processes, and in trauma stress management and evaluation of fitness for duty. Concerns related to police diversity and police family issues are also addressed, as are unique aspects of police stress management. Additional chapters are dedicated to establishing psychological service functions that currently are less familiar to police agencies than they are to other government and private sector service recipients. These chapters are devoted to police psychologists as human resource professionals, as human factors experts in accommodating to new technology and to new legal requirements, as organizational behavioral experts, and as strategic planners. This text is recommended reading for two groups: *police and public safety administators whose work takes them--or should take them--into contact with police psychologists; *practicing and would-be police psychologists concerned with the emerging trends in the application of psychology to police and other public safety programs.

This book examines the experiences of relatives of those accused or convicted of serious crimes such as murder, manslaughter, rape and sex offences. A broader literature exists on prisoners' families, but few studies have looked specifically at those related to serious offenders, or considered their experience other than as prison visitors. Many of the difficulties faced by 'mundane' prisoners' families are magnified for the relatives of serious offenders, first by the length of sentence, and secondly by the seriousness and stigmatizing impact through association of the offence itself.
Families Shamed draws upon intense qualitative research which combines long, searching interviews with the relatives of serious offenders with ethnographic fieldwork over a period of several years. The book focuses on how relatives made sense of their experiences, individually and collectively: how they described the difficulties they faced; whether they were blamed and shamed and in what manner; how they understood the offence and the circumstances which had brought it about; and how they dealt with the contradiction inherent in supporting someone and yet not condoning his or her actions.
This is the first book to tell the story of serious offenders' families, the difficulties they face, and their attempts to overcome them. At the same time a focus on offenders' families also draws our attention to the ways in which women are affected by crime, illuminating the broader effects of crime and the criminal justice process on the proportionately greater number of women involved. It contributes also to wider debates about the social organization of the meanings of crime, and questions the tenability of some core policy assumptions about offenders and their families; the relationship between the state and the family, and its bearing especially on expectations about family responsibilities.

This two-volume book is a comprehensive guide to designing, conducting and interpreting experiments in a broad range of topics associated with hydraulic engineering. It is the first substantial effort in hydraulic engineering to assemble in one place descriptions of all the components of experimentation along with a concise outline of essential theory to highlight the intrinsic connection between analytical and experimental research and illustrate the need for their complementary use. Providing end-to-end guidance to support experimentalists is long overdue, as most of the information can only be found in scientific papers or specialized monographs on laboratory and fieldwork practice. The book was prepared for college faculty, researchers, practitioners, and students involved in hydraulics experiments. Written by a team of more than 45 authors well-experienced in hydraulics experimentation, the book takes into account experiments performed under a range of conditions, including well-equipped and -staffed laboratories, and laboratories lacking aspects of advanced instrumentation and expertise. The book could serve as a textbook on hydraulics experiments. Its style is intentionally concise and makes frequent use of convenient summaries, tables and figures to present information. The writers provide specific guidance on methods and instruments currently used in hydraulics experiments, and emphasizes new and emerging measurement technologies and analysis methods. Extensive references enable interested readers to further explore details on each topic. Although the book focuses primarily on laboratory experiments, including hydraulic modelling, it also applies to fieldwork of varying complexity and accessibility.

Modeling hydrologic changes and predicting their impact on watersheds is a dominant concern for hydrologists and other water resource professionals, civil and environmental engineers, and urban and regional planners. As such changes continue, it becomes more essential to have the most up-to-date tools with which to perform the proper analyses and modeling of the complex ecology, morphology, and physical processes that occur within watersheds. An application-oriented text, Modeling Hydrologic Change: Statistical Methods provides a step-by-step presentation of modeling procedures to help you properly analyze and model real-world data.

The text addresses modeling systems where change has affected data that will be used to calibrate and test models of the system. The use of actual hydrologic data will help you learn how to handle the vagaries of real-world hydrologic-change data. All four elements of the modeling process are discussed: conceptualization, formulation, calibration, and verification. Although the book is oriented towards the statistical aspects of modeling, a strong background in statistics is not required. The statistical and modeling methods discussed here will be of value to all disciplines involved in modeling change. With approximately 100 illustrations, Modeling Hydrologic Change will equip you with an understanding with which to perform the proper analyses and modeling of the complex processes that occur across various disciplines.

Stepped channel designs have been used for more than 3,500 years. A significant number of dams were built with overflow stepped spillways during the nineteenth and early twentieth centuries, before the design technique became outdated with the progresses in hydraulic jump stilling basin design. Recent advances in technology (e.g. RCC, polymer-coated gabion wire) have triggered a regain in interest for the stepped design, although much expertise had been lost in the last eighty years. The steps increase significantly the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are used also in water treatment plants to enhance the air-water transfer of atmospheric gases (e.g. oxygen, nitrogen) and of volatile organic components (VOC). This book presents the state-of-the-art in stepped channel hydraulics. It is based upon the research expertise of the writer, his professional experience as an expert-consultant, and his experience in teaching stepped spillway hydraulics to undergraduate students, postgraduate research students and professionals since 1982. Results from more than forty-five laboratory studies and four prototype investigations were reanalyzed and compared, enabling the book to provide a new understanding of stepped channel hydraulics, aimed at both the research and professional communities.
