The purpose of this paper is to demonstrate a “maintenance pathway” for ensuring a low false negative rate in closing investigations unlikely to lead to a clearance (detection).

A randomised controlled experiment testing solvability factors for non-domestic cases of minor violence.

A random selection of 788 cases, of which 428 would have been screened out, were sent forward for full investigation. The number of cases actually detected was 22. A total of 19 of these were from the 360 recommended for allocation. This represents an improvement of accuracy over the original tests of the model three years earlier.

This study shows how the safety of an investigative triage tool can be checked on a continuous basis for accuracy in predicting the cases unlikely to be solved if referred for full investigations.

This safety check pathway means that many more cases can be closed after preliminary investigations, thus saving substantial time for working on cases more likely to yield a detection if sufficient time is put into the cases.

More offenders may be caught and brought to justice by using triage with a safety backstop for accurate forecasting.

This is the first published study of a maintenance pathway based on a random selection of cases that would otherwise not have been investigated. If widely applied, it could yield far greater time for police to pursue high-harm, serious violence.

Reassesses the Minneapolis Domestic Violence Experiment (MDVE) data of the 1980s which said that “arrest works best”. Examines the potential effects of a small number of officers generating a relatively large number of MDVE cases. Expresses concern that a few officers submitting a high rate of cases might have an inordinately large effect on the experimental outcomes. Seeks to determine whether they followed the experimental protocol but finds instead that it was the low rate officers who failed to do so. Finds that officers who submitted experimental cases at a high rate were also different in other ways from the rest of the officers. Finally, excludes findings relating to lower case officers and thereby reveals that recidivism in domestic violence was not reduced by the arrests.

Although numerous studies recently have appeared that identify the most‐cited scholars and works in the general criminology and criminal justice literature and in several specialty areas, no previous citation study has specifically examined the police studies literature. Through an analysis of 370 articles and research notes appearing from 1991 to 1995 in the areas of police studies, published in Criminology, Justice Quarterly, and four academic periodicals devoted to police studies, we list the 50 most‐cited scholars and the 36 most‐cited works. The lists of the most‐cited scholars and works in the specialty area of police studies are compared to general lists taken from leading criminology and criminal justice journals and introductory textbooks. We conclude with some thoughts about the relevance of citation analysis to specialists in police studies.

The purpose of this paper is to explain why Singapore has succeeded in curbing the problem of police corruption and to identify the six lessons which other Asian countries can learn from Singapore's experience.

The paper analyzes the causes of police corruption in Singapore during the British colonial period and describes the measures adopted by the People's Action Party government after assuming office in June 1959 to curb police corruption. The effectiveness of these measures is assessed by referring to Singapore's perceived extent of corruption according to three international indicators and the reported cases of police corruption from 1965 to 2011.

The Singapore Police Force has succeeded in minimizing police corruption by improving salaries and working conditions, cooperating with the Corrupt Practices Investigation Bureau, enhancing its recruitment and selection procedures, providing training and values education for its members, and adopting administrative measures to reduce the opportunities for corruption. Other Asian countries afflicted with rampant police corruption can learn six lessons from Singapore's success.

This paper will be of interest to those policy makers, scholars, and anti-corruption practitioners, who are interested in learning how Singapore has succeeded in curbing police corruption.

The chapter considers the change of position of the Home Office on the value of randomised controlled trials (RCTs) in England and Wales which took place around 2003 after the end of the Crime Reduction Programme (CRP). Before the CRP Home Office researchers had shown little interest in RCTs; after it, they came close to arguing that no other kinds of evaluation research were worth doing. This represented a reversal of a position that had dominated Home Office thinking on the issue for almost 30 years – that RCTs were in general impractical and unlikely to produce clear-cut results. This view was based in part on the experience of RCTs in the 1970s, which led influential researchers to conclude that the method could not be transferred from medicine to criminal justice. But, disappointed with the lack of definite results from the CRP, the Home Office turned back to RCTs as a potential source of certainty about what works. The chapter considers two recent scholarly exchanges on the question, in relation to an evaluation of a community crime reduction programme, for which an experimental design was attempted but not achieved, and to Lawrence Sherman's recent advocacy of RCTs and his use of research on restorative justice as an example of the successful use of the method. The chapter argues that the restorative justice research, while of very high quality, does not provide as clear an example of the use of an RCT as Sherman claims, and concludes with some reflections on the inherent difficulties of criminal justice evaluation, and on the lack of a predictable, rational relationship between research quality and policy influence.

Major concern over monopolies and trusts was one of the distinguishing marks of the American Economic Association from its foundation and lasted well into the early 1900s (Coats, 1960). The failed merger attempt of the Northern Securities Company and the subsequent panic of 1902–1903, the 1907 financial crisis and its aftermath, as well as the ostensibly illegal financial practices of many conglomerates, all contributed to keep the trusts issue alive on academic circles. But it was only after the 1911 Court decisions that the debate on the trust problem and the necessary measures to amend the existing antitrust legislation acquired new vigor and incisiveness.³

This chapter develops a productivity analysis of the New Jersey PPO Health Insurance Industry for 2018. The chapter concerns five New Jersey PPO insurance companies. The two output variables are claims paid and loss ratio. The two input variables include premiums collected and assets.

This chapter develops a productivity analysis of the US pharmaceutical industry via Data Envelopment Analysis (DEA). This study concerns itself with 16 US pharmaceutical companies. The output variables are profit margin, operating margin, return on assets, and return on equity. The input variables are corporate workers and market capital. Since negative data appear in DEA, a directional distance approach was applied.
