Testing for Analysts’ Bias in Crime Prevention Experiments: Can We Accept Eisner’s One-tailed Test?

Eisner (Journal of Experimental Criminology, this issue, 2009) suggests that developer-led evaluations often make programs look better than independent evaluations do because the former suffer systematic biases in favor of prevention success. Yet, his proposed remedies suffer their own systematic bias, constituting a ‘one-tailed’ test of bias in only one direction. In this response we suggest that a more objective assessment of ‘analysts’ effects’ requires a ‘two-tailed’ test of bias, in which reviewers would measure indications of bias both for and against success in evaluations reported by both developers and independent evaluators. After exploring the full complexity of the distinction between developers and evaluators, we report on one case in which independent evaluations were more favorable than those of developers. We then suggest possible indicators of analysts’ biases against finding success that may characterize the work of developers who “bend over backwards” to find harm in their programs, and of independent evaluators who may seek to “get a scalp” of a developer or a program.

Singular memory or institutional memories? Toward a dynamic approach

The ability of the civil service to act as a reservoir of institutional memory is central to the pragmatic task of governing. But there is a growing body of scholarship that suggests the bureaucracy is failing at this core task. In this article, we distinguish between two different ways of thinking about institutional memory: one “static” and one “dynamic.” In the former, memory is singular and held in document form, especially by files and procedures. In the latter, memories reside with people and are thus dispersed across the array of actors that make up the differentiated polity. Drawing on four policy examples from three countries, we argue that a more dynamic understanding of the way institutions remember is both empirically salient and normatively desirable. We conclude that the current conceptualization of institutional memory needs to be recalibrated to fit the types of policy learning practices required by modern collaborative governance.     

Suicidal Ideation Among Women Court-Referred to Batterer Intervention Programs

Identifying the prevalence and correlates of suicidal ideation in women mandated to batterer intervention programs is necessary to prevent suicide in this greatly understudied population. This study used cross-sectional, self-report survey methodology to identify the prevalence and correlates of suicidal ideation among 79 women attending batterer intervention programs. Of the sample, 33% reported experiencing suicidal ideation during the two weeks prior to entering the program. Multiple linear regression analysis indicated that (while controlling for number of batterer intervention sessions attended) symptoms of depression and borderline personality disorder, but not symptoms of antisocial personality disorder, were associated with suicidal ideation.     

The Queensland Native Police and Strategies of Recruitment on the Queensland Frontier, 1849–1901

Although historians have provided substantial insights into the structure, development and activities of the Queensland Native Mounted Police, they have rarely focused on the complex and sensitive issue of Aboriginal recruitment. A careful reading of historical records, however, identifies several methods, including coercion, intimidation, kidnapping and inducement, as well as “voluntary” enlistment. It is difficult to identify Aboriginal agency in recruitment processes as the records are entirely one-sided—the voices of the troopers themselves are absent from the archival sources. In this article, we examine the cultural and historical contexts of Aboriginal recruitment—for example, the dire social situations of Aboriginal survivors of the frontier war and the absence of future survival options for the potential recruits. We explore, through the framework of historical trauma, the impacts on vulnerable victims of violence and other devastating effects of colonisation. We conclude that the recruitment of Aboriginal troopers was far from a homogeneous or transparent process and that the concept of agency with regard to those who can be considered war victims themselves is extremely complex. Unravelling the diverse, conflicting and often controversial meanings of this particular colonial activity remains a challenge to the historical process.     

Involvement in extreme violence and violence‐related trauma: A review with relevance to young people in custody

Purpose. This review is concerned with the points of contact between two diverse literatures: first, the association between childhood abuse and the development of violent conduct; second, the effects of involvement in the perpetration of acts of violence. Method. The empirical literature in the two areas of concern is considered along with complementary explanations for the extant evidence. Results. There is a weight of evidence indicating that childhood abuse is associated with later violence alongside a literature that considers this association in terms of the traumatic effects of abuse. The perpetration of violent acts can have debilitating effects on the individual offender: these effects have also been considered in terms of trauma. Conclusion. It is suggested that there are potential advantages to adopting a trauma‐based framework to inform practice with violent young people. This suggestion raises several areas for research to inform the development of evidence‐based practice that are presented in outline form.     

The importance of scientific evaluation of biological evidence — Data from eight years of case review

In 2009, the National Research Council published a report stating that the addition of more science and technology into the field of forensic science in the United States would be of great benefit to the judicial system. As a starting point to address this NRC report, one needs to make an assessment of the system. One factor that is continuously requested is an estimate of an error rate. In any given scientific area of forensics that is difficult to quantitate except by external review and audits. After eight years of requested defense review of cases with biological and DNA evidence, most cases appear to be scientifically sound in test methods and procedures. However, there were some cases where errors in the forensic science process did occur. This article takes information compiled from those eight years of defense review and summarizes the cases where errors have been discovered and discusses the scientific implications of these errors. The scope of this article is limited to crime scene collection and forensic science laboratory testing of biological materials for body fluid identification and DNA individualization to a source. The greatest value of defense review comes from (a) providing effective balance and independent oversight to the judicial process and (b) collecting data into a format that can be useful as a guide in training programs.     

The influence of vehicle model and colour on assessments of speed and culpability: the case for (and against) Computer Generated Exhibits (CGE)

Computer Generated Exhibits (CGE) are frequently deployed in legal contexts under the rubric of demonstrative evidence, i.e. to facilitate juror comprehension. However, a number of legal and academic commentators have suggested that the nature of the computerised moving image could exert undue prejudice on decision makers, e.g. judge and/or jury. The current study aimed to assess the manipulation of vehicle characteristics (make and colour) when a road traffic accident was presented in the format of a computer generated animation (CGA). In experiment 1, two groups of subjects watched two different makes of car, a Range Rover Sport and a Volkswagen Touran in a black-and-white format; no significant differences emerged over vehicle model with regards to vehicle speed or overall responsibility for the accident. Experiment 2 presented the same vehicles to four groups of participants in full colour, with the cars in contrasting red or beige; significant differences emerged with regards to culpability for vehicle make only. The findings could have implications for the format and style of CGE used in legal settings.
