Working together to cut numbers in the criminal justice system

Here at the Centre for Crime and Justice Studies, we are not strictly speaking a campaigning organisation. However, we are interested in forming a coalition with academics, practitioners, our members and all those for whom the current rate of imprisonment and the government's concerted lack of commitment to the significant reduction of prison numbers, is of grave and ongoing concern; it is unacceptable.     

Evidence on substitutability of adult and child labour

Whether child labour displaces adult labour, giving rise to unemployment, is a matter of their substitutability in production. Using a flexible form production function fitted to data on Egypt's economy, we generate Hicks elasticities of complementarity, own and cross‐price elasticities, as well as simulate employment effects on adult labour as a result of changing the fixed quantity of labour in compliance with the international call to end child labour. Adult males appear to be complementary with, and adult females substitutes for child labour, although the employment effects of banning child labour are inconclusive.     

Serial killers with military experience: applying learning theory to serial murder

Scholars have endeavored to study the motivation and causality behind serial murder by researching biological, psychological, and sociological variables. Some of these studies have provided support for the relationship between these variables and serial murder. However, the study of serial murder continues to be an exploratory rather than explanatory research topic. This article examines the possible link between serial killers and military service. Citing previous research using social learning theory for the study of murder, this article explores how potential serial killers learn to reinforce violence, aggression, and murder in military boot camps. As with other variables considered in serial killer research, military experience alone cannot account for all cases of serial murder. Future research should continue to examine this possible link.     

The intersection of gender politics and religious beliefs

Traditional understanding has placed conservatism at the intersection of religion and politics and has assumed that this relationship is stronger for women than it is for men. Yet rarely has gender been a principal analytic category in such explorations, and the relationships have not been thoroughly documented. We analyze the 1980 and 1984 National Election Study data and find that religion is not a more conservatizing influence on voting behavior for women than it is for men. Reagan did best with the small group of women fundamentalist believers, and did rather well among highly religious Catholic women. In most other cases the gender gap actually widened with increasing religiosity. Although women are more religious than men, political observers are cautioned that this finding cannot be taken as evidence of women's greater support for conservative candidates.     

Keys to Implementation of Child Welfare Systems Change Initiatives

While the research base on implementation in child welfare has grown, applying implementation science to child welfare system change is still relatively new. There is a gap in knowledge of what factors are most important in different implementation stages and system contexts. This study examines 12 implementation keys that support building infrastructure, developing inter-organizational networks, and addressing contextual issues in child welfare system change initiatives in three states. Research questions address which keys are most important in different implementation stages, the major components and context of these keys during implementation, and the overlap between implementation keys.     

The Impact of Hot Spots Policing on Collective Efficacy: Findings from a Randomized Field Trial

In disadvantaged neighborhoods, prior research has found reduced social cohesion and less willingness among residents to address disruptive behaviors and violations of social norms. This deficiency is commonly associated with higher levels of disorder and crime. Therefore, recent scholarship has begun to consider whether police can help foster collective efficacy, especially in places struggling with serious crime problems. Early results are somewhat mixed. Yet the cooperation hypothesis asserts that when neighborhood residents see police as a more viable and reliable resource, residents will be emboldened to exert informal social control to address problems. Over the last two decades, hot spots policing has been recognized as an effective method to reduce crime. At the same time, there have been few rigorous studies of whether this approach impacts collective efficacy at hot spots. To investigate this question, we conducted an experiment in 71 crime hot spots, comparing a collaborative problem solving versus a directed patrol (police presence) approach versus standard policing practices. Over time, a substantial increase in police presence did appear to promote modest improvements in collective efficacy. We attribute this finding to the cooperation hypothesis.     

Applying police legitimacy,cooperation, and collective security hypotheses to explain collective efficacy and violence across neighbourhoods

This study examines views about police legitimacy and competence in neighbourhoods over time. The study compares theories about police legitimacy, the cooperation hypothesis, and the collective security hypothesis to predict violence. Findings suggest that when police legitimacy is deficient in neighbourhoods, a culture supportive of violence to resolve disputes may develop. Results show the importance of police competence to suppress violence and build collective efficacy. Finally, police are more successful in neighbourhoods that are collectively efficacious. The cooperation hypothesis is fully supported, but the collective security hypothesis and LaFree’s legitimacy theory receive partial support. Findings underscore the merit of examining neighbourhood consequences of police legitimacy, including how institutions, like police, can impact neighbourhood socialisation processes and are impacted by them.     

idPAD: Paper Analytical Device for Presumptive Identification of Illicit Drugs

As drug overdose deaths across the United States continue to rise, there is increasing interest in field testing of illicit substances. This work discusses a paper-based analytical device (idPAD) that can run a library of 12 colorimetric tests at the same time, each detecting different chemical functional groups and materials found in illicit drugs, distractor substances, and cutting agents. The idPAD requires no electricity, costs less than $2 USD, and requires minimal training to operate. The results of the 12 tests form a color barcode which is “read” by comparison to standard images. The accuracy of the idPAD was assessed using samples of heroin, cocaine HCl, crack, and methamphetamine at concentrations of 25%–100% in a lactose matrix, as well as pure lactose. Based on 840 “reads” by three different users, the idPAD showed 95% sensitivity and 100% specificity for detecting these drugs; the most common error was mistaking cocaine HCl for crack or crack for cocaine HCl. In a second step, samples of heroin, cocaine, and methamphetamine (n = 30) and distractor substances (pharmaceuticals, cutting agents, and other illicit drugs, n = 64) were tested by two readers, yielding a sensitivity of 100% and specificity of 97%. Targeted substances were detected reliably at 55–180 μg/lane, and the idPAD was found to be stable for at least 3 months when stored at room temperature. The library approach used in the idPAD may provide the accuracy and robustness necessary for a presumptive field drug test.
