Evaluation of Bluestar® Forensic Magnum and Other Traditional Blood Detection Methods on Bloodstained Wood Subjected to a Variety of Burn Conditions,

Accurate blood detection is a primary concern for forensic scientists, especially in highly compromised situations. In this study, blood was added to wood blocks and subjected to a variety of fire treatments: the absence or presence of accelerant, burn time (1, 3, or 5 min), and extinguishment method (smothering or dousing with water). Burned blocks were given a qualitative burn score, followed by removal of half of the char from each block and subsequent testing of each half for blood using luminol (13% positive; n = 96), Bluestar^® Forensic Magnum (5.2% positive; n = 96), and combined phenolphthalein tetramethylbenzidine test (0% positive; n = 192). Luminol and Bluestar® Forensic Magnum performed similarly, both outperforming PTMB. Additionally, positive results were more likely from samples that were smothered, had a low burn score, and had more concentrated blood solutions (neat or 1:2). Overall, it is extremely unlikely that blood would be detected on combustible substrates exposed to direct fire.     

Two paradigms of justice: criminal vs survivor justice in Africa

African countries continue to experience civil wars and other low-level violent conflicts. An issue relating to the intractable nature of postcolonial violence and how it should be resolved, is what is the potential for advancing contemporary peace processes and negotiated agreements through the notion of survivor justice? Two paradigms of justice have emerged in Africa in response to mass violence: criminal justice based on the example of the Nuremberg trials; and survivor justice based on political reform and exemplified by the cases of South Africa and Sudan. These two paradigms of justice are compared, with the context undergirding the debate and assumptions of each explored, and how this related to the issues of building peace in Africa. The guiding question is whether civil wars can be ended in courts. I argue that where a decisive military victory is untenable, survivor justice, that is political reform combined with judicial reconciliation, is the best way to resolve Africa’s conflicts. The example of South Africa’s political settlement and the reconciliation process in Rwanda offer examples of solutions for conflict transition to peace. Criminal justice processes – absent a decisive military victory – can act to delay and prevent peace and resolution.     

Effects of genetic and environmental explanations of psychopathy and gender on perceptions of criminal behaviors

Genetic/biological evidence is increasingly introduced into courtrooms but findings regarding its impact are mixed. This study integrates research on psychopathy and the use of genetic evidence in legal contexts by considering how information on genetic causal accounts of psychopathy affect perceptions of culpability, recidivism, amenability to treatment, and sentencing severity. Perpetrator gender was examined as a moderator. Two-hundred thirty-eight undergraduates read a hypothetical violent crime vignette and mock expert testimony regarding psychopathy. The testimony included a diagnosis only, or a diagnosis plus genetic or environmental explanations of the etiology of psychopathy. Results indicated that a genetic account of psychopathy was not clearly perceived as aggravating or mitigating such that participants were more lenient in their perceptions of culpability yet more punitive in their sentencing recommendations when perpetrators were described to have genetically-caused psychopathy. An environmental account of psychopathy was mitigating but only for sentencing severity. In addition, although participants were more lenient in sentencing male and female perpetrators when provided with an environmental cause of psychopathy, participants judged male perpetrators most harshly when provided with a genetic cause of psychopathy. Implications of the relations between etiology and gender in legal decision-making are discussed.     

Estimating Sex Using Metric Analysis of the Scapula by Postmortem Computed Tomography

Postmortem computed tomography (CT) has been extensively used in the last decade for identification purposes and in various anthropologic studies. Postmortem CT measurements of scapulae, analyzed using logistic discriminant function developed in this study, showed 94.5% accuracy in estimating sex. Data analyzed using the Dabbs and Moore‐Jansen (2010) discriminant function and the discriminant function generated in this study provided nearly identical results with disagreement in only one case. Height and weight were not statically significant in sex prediction. The results of this study show that data obtained from volume rendered postmortem CT images can be considered reliable and treated as a practical option to standard anthropological methods, especially in mass fatalities as a rapid triage tool for sex determination.     

The Grooved Pegboard Test as a Validity Indicator—a Study on Psychogenic Interference as a Confound in Performance Validity Research

This study was designed to replicate an earlier report on the link between low scores on the Grooved Pegboard test (GPB), invalid responding, and elevated self-reported psychiatric symptoms. A fixed battery of neuropsychological tests was administered to 100 consecutively referred outpatients (M_Age?=?38.3, M_Education?=?13.6 years) following traumatic brain injury at a Midwestern academic medical center. Classification accuracy of GPB validity cutoffs was computed against a free-standing PVT and three composite measures of embedded validity indicators. Previously suggested GPB validity cutoffs (T?≤?29 in either hand) produced good combinations of sensitivity (0.25–0.55) and specificity (0.89–0.98) to psychometrically defined invalid performance. Raising the cutoff to T?≤?31 resulted in a reasonable trade-off between increased sensitivity (0.36–0.55) and decreased specificity (0.84–0.94). T?≤?31 in both hands was highly specific (0.93–0.98) to noncredible responding. GPB validity cutoffs were unrelated to psychiatric symptoms or injury severity. Failing PVTs based on forced choice recognition was associated with elevated self-reported depression, somatic concerns, and overall symptomatology. Low scores on the GPB are reliable indicators of noncredible responding. Self-reported emotional distress has a complex relationship with performance validity. Psychogenic interference is a potential mechanism behind PVT failures, and its expression is likely mediated by instrumentation and sampling artifacts. Further research on the topic is clearly needed to advance current understanding of psychogenic interference as a confound in cognitive testing.     

Nobody gives a #%&!: a factorial survey examining the effect of criminological evidence on opposition to sex offender residence restrictions

Objectives

This short report tests whether altering messages concerning the presentation (i.e., criminal justice actor experience vs. summary of scientific findings) or nature of criminological research findings (i.e., lack of crime control effect vs. collateral consequences) regarding the (in)efficacy of sex offender residence restrictions (SORR) would subsequently affect public support for this policy.

Methods

The experimental conditions were presented in a factorial survey delivered to a national online panel, which was subsequently matched to a sampling frame representative of US adults on the basis of gender, age, race, education, ideology, and political interest (N?=?970). Analysis of variance was used to estimate the impact of the experimental manipulations on SORR opposition.

Results

Support for SORR was high across all experimental conditions, and no manipulations were statistically associated with variation in opposition to the policy.

Conclusions

The results support limited previous research suggesting that the public would continue to support SORR even in the lack of evidence to its effectiveness. This research suggests that altering the presenter or nature of research evidence subsequently produces no opinion change, at least in the form that was executed here. Further research on the mechanisms underlying the recalcitrance of SORR support is necessary.

     

The Views of Psychologists,Lawyers, and Judges on Key Components and the Quality of Child Custody Evaluations in Australia

This study aimed to understand the expectations of and the agreement between professional groups regarding the quality of single‐expert reports written by psychologists (known as child custody evaluations in the United States). 13 psychologists, 18 family lawyers, 26 children's lawyers, and 8 judges (N = 65) in New South Wales, Australia, rated the overall quality of reports and the quality of various components of them. Interprofessional congruence on importance ratings allowed key components to be derived. The results revealed that the overall quality of reports was rated positively, however, significant discrepancies were found between importance and quality ratings on the various components, indicating that reports fall short of expectations in many areas.     

Banking in the cloud: Part 3 – contractual issues

This paper looks at EU banks' use of public cloud computing services. It is based primarily on anonymised interviews with banks, cloud providers, advisers, and financial services regulators. The findings are presented in three parts. Part 1 of this paper explored the extent to which banks operating in the EU, including global banks, use public cloud computing services. Part 2 of this paper covered the main legal and regulatory issues that may affect banks' use of cloud services.Part 3 looks at the key contractual issues that arise in negotiations between banks and cloud service providers, including data protection requirements, complexities caused by the layering of cloud services, termination, service changes, and liability. It also presents the overall conclusion derived from the studies conducted, as set out in the three parts of the paper.All three parts of the paper can be accessed via Computer Law and Security Review's page on ScienceDirect at: http://www.sciencedirect.com/science/journal/02673649?sdc=2.

The Adaptation of License-plate Readers for Investigative Purposes: Police Technology and Innovation Re-invention

Scholarship has focused on the use of license plate readers by patrol officers as a rational instrument for accomplishing key policing goals, including recovering stolen vehicles. In contrast, this paper applies the theoretical framework of innovation reinvention to explain how license plate readers are being used by criminal investigators in more novel ways. This perspective provides insights into the practical benefits of an enhanced version of this technology. More significantly, it helps illuminate the innovation attributes and the organizational determinants that contribute to its adaptation. In our case study of an agency with extensive deployment of license plate readers, we found that factors contributing to their reinvention included their widespread availability and compatibility with other information systems, their lack of complexity, the characteristics of their users, and the role of leadership in promoting their use. These findings have implications for advancing knowledge about the complex nature of the innovation process.     

Assessing the Effects of Court Date Notifications within Pretrial Case Processing

Jurisdictions at every level throughout the U.S. are paying an increasing amount of attention to pretrial case processing. The primary areas of attention appear to be on risk assessment development and classification, the effects of pretrial detention, and the effectiveness of various strategies that may impact a defendant’s failure to appear for their assigned court dates. The current study is a randomized experimental trial designed to test the effects of court notification strategies, using failure to appear (FTA) as the primary outcome of interest. Our findings do not reveal a palpable effect for court notification strategies (telephone calls, and text messaging, with other conditions layered in), but do indicate and reinforce the utility of an actuarial method of risk classification when predicting likelihood of FTA.
