The criminal investigation process by Peter W Greenwood( Book )

15 editions published between 1970 and 1977 in English and held by 541 WorldCat member libraries worldwide

The criminal investigation process in municipal and county police departments was studied by survey, interviews and observations, and special data collection. Investigators spend about 7% of their time on activities that lead to solving crimes. Case solutions reflect activities of patrol officers, members of the public, and routine clerical processing more than investigative techniques. Nearly half of investigators' case-related activities are devoted to post-arrest processing; these activities are inadequately responsive to the needs of prosecutors. Collecting physical evidence at crime scenes does not help solve crimes unless evidence processing capabilities are adequate. Policy implications are discussed. (Author)
Redefining the career criminal : priority prosecution of high-rate dangerous offenders by Marcia R Chaiken( Book )

6 editions published in 1990 in English and held by 391 WorldCat member libraries worldwide

Varieties of criminal behavior : summary and policy implications by Jan M Chaiken( Book )

16 editions published between 1981 and 1982 in English and held by 353 WorldCat member libraries worldwide

Analysis of self-report and official record data obtained from nearly 2,200 male prison and jail inmates in California, Michigan, and Texas shows that offenders can be usefully classified according to the combinations of crimes they commit. The most serious inmates, those who concurrently commit robbery, assault, and drug dealing, disproportionately commit these defining crimes at high rates. They often commit burglaries, thefts, and other crimes at high rates too--frequently at higher rates than other types of criminals, including those who specialize in those crimes. Unfortunately, information currently available from such sources as official arrest and conviction records do not permit criminal justice officials to distinguish meaningfully between these high-rate, serious offenders and other types. Much better distinctions can be made using potentially available information on key characteristics: multiple drug use, unstable employment, juvenile use of hard drugs, and violence before the age of 16

A patrol car allocation model by Jan M Chaiken( Book )

37 editions published between 1970 and 1985 in English and Undetermined and held by 276 WorldCat member libraries worldwide

This report describes the Patrol Car Allocation Model (PCAM85), a computer program to assist police agencies determine the number of patrol cars to have on duty in each geographic command at different times of the day and week; a user's guide to PCAM is included. Descriptions of the capabilities and uses of the model encompass typical applications, the role of judgment in using PCAM, and the major differences between PCAM75 and PCAM85 (PCAM85 is a modernized version of the original model developed in 1975). The discussion reviews general operation principles, preparation of a data base, data required for each patrol hour, calculation of performance measures, and prescriptive calculations. The user's guide to PCAM opens with an overview of program operation and then specifies how to enter commands, command format conventions, program vocabulary, and command definitions. The guide also explains error conditions and selecting an objective function. The appendixes contain information on PCAM's calculations, PCAM reference sheets, and addresses for further information. A glossary, 19 figures, and a 40-item bibliography are also provided

Investigators who perform well by Bernard Cohen( Book )

4 editions published in 1987 in English and held by 232 WorldCat member libraries worldwide

This volume presents the results of a study to find the best methods for law enforcement agencies to use in selecting investigators and evaluating their performance. The report is written for detective supervisors and managers, personnel department heads, and attorneys who deal with equal employment opportunity litigation. Information gathering for the study included interviews with personnel in a dozen police jurisdictions throughout the United States. Key elements of the selection process, the authors found, are fairness, validity, job relatedness, utility, and efficiency. While college study and past job performance (including rates of conviction) were good indicators of future investigative performance, written civil service examinations and tests for verbal ability were the only factors that achieved the validity standards for job relatedness required under most EEO regulations.

Patrol allocation methodology for police departments by United States( Book )

8 editions published between 1975 and 1977 in English and held by 215 WorldCat member libraries worldwide

This report reviews mathematical modeling methods that have been developed to assist police departments in allocating patrol resources. Issues discussed include: determining the number of patrol cars to have on duty by geography and time of day, designing patrol beats, developing policy for dispatching and redeployment of patrol cars, scheduling manpower to match the variations in the number of cars needed on duty. Traditional approaches to the first issue are based hazard formulas or workload formulas, but better than either of these are computer programs that calculate a variety of performance measures and recommend allocations that meet the objectives established by the department. For designing patrol beats, two models are available. These require much more detailed data than a model for allocating patrol units and should generally be used after a department has determined the appropriate number of units to have on duty. Either model will guide the planner to substantially better beat designs than he can obtain using only a map and manual calculations. Issues of dispatching and redeployment policy are best resolved using simulation models, which are much more expensive and difficult to use than either allocation or beat design models. Most departments would require outside analytical assistance to analyze such issues. Manpower scheduling issues are of several types, and the choice of a suitable model depends on understanding the distinctions among them. Some of these models are very flexible, and most are relatively easy to use. The schedules they generate can be considerable improvements over those now in use in most departments. Guidelines are presented for the organization of a well-managed study of patrol allocation. They deal with the collection and processing of data, assembling a project teams, utilizing available computer programs, and developing new policy

Fire department deployment analysis : a public policy analysis case study by Rand Fire Project( Book )

4 editions published between 1979 and 1993 in English and held by 154 WorldCat member libraries worldwide

This book is about fire department deployment--deciding how many firehouses and fire companies a department should have, where they should be located, which companies should be dispatched as incidents occur, and how and when to relocate them. Some topics discussed have national, and even international, implications. Others concentrate on administrative and operational concerns in local government, with particular reference to fire departments. At the finest level of detail, the book describes practical procedures for data collection, the mathematical formulation of deployment models, and related aspects of analysis
What's known about deterrent effects of police activities by Jan M Chaiken( Book )

12 editions published between 1970 and 1977 in English and held by 149 WorldCat member libraries worldwide

Several techniques have been used to estimate the effect of police activities on the incidence of crime, including: (1) cross-sectional analysis of reported crime rates in various jurisdictions as compared to resources devoted to the totality of police functions or certain police functions, (2) longitudinal analysis of a time series of crime incidence in several jurisdictions or in a single jurisdiction where police deployment or operations changed over time, and (3) experimental manipulation of the nature or amount of police activities. Nearly every study concerning deterrence has been subjected to criticism for one or more faults, such as failure to distinguish between true and reported crime rates, failure to specify or maintain the experimental conditions, apparent errors in the data, or confusion between cause and effect
The Impact of fiscal limitation on California's criminal justice system by Rand Corporation( Book )

7 editions published between 1980 and 1985 in English and held by 140 WorldCat member libraries worldwide

Proposition 13, effective July 1978, marked a turning point in funding of California's criminal justice system. This report presents information on revenue and expenditure trends both before and after passage of Proposition 13, examines the response of each of the elements of the criminal justice system during the first year, and identifies general trends and patterns that may have significant implications for the future. Among the trends are attempts to apply short-term solutions to long-term problems, a growing influence of the state and federal governments over local government activities, a growing conflict between local government autonomy and the mandates and dictates of higher-level governments, and changes in the goals and objectives of the criminal justice system that portend a less humane and less responsive system
Identifying high-rate serious criminals from official records by John E Rolph( Book )

7 editions published in 1987 in English and held by 127 WorldCat member libraries worldwide

Can official criminal records reliably be used to conclude that certain offenders are committing serious crimes at high rates? By comparing official records with self reports of criminal activity collected in RAND's second inmate survey, this study finds that commonly available official criminal history data are of only marginal help in discriminating between high-rate serious offenders and others. Using additional self-reported data on offenders' backgrounds, particularly regarding substance abuse and early juvenile criminal activity, improves the identification to about 36 percent over what can be achieved by chance

Methods for allocating urban emergency units by Jan M Chaiken( Book )

9 editions published between 1969 and 1972 in English and held by 112 WorldCat member libraries worldwide

This report is a survey of current research on allocation or municipal emergency service systems, with the emphasis on police patrol cars and fire engines and ladders. It describes those results which have produced, or are likely to produce, substantial improvements in system performance when implemented. The aspects of allocation policy discussed include: determining the number of units (vehicles) to have on duty in each geographical area at different times of the day or week; selecting the unit(s) to respond to a particular incident; determining the locations or patrol areas for the units on duty, and designing patrol coverage patterns; deciding when units should be redeployed to improve service in areas where a large number of units are temporarily busy
