A partial assessment of South Carolina's Project Safe Neighborhoods strategy: Evidence from a sample of supervised offenders

Since 2001, the federal Project Safe Neighborhoods initiative has instituted a comprehensive effort to reduce gun crimes in local communities across the United States. In South Carolina, the United States Attorney's Office for the District of South Carolina established Project CeaseFire, a localized response to reduce the prevalence of gun crime through targeted prosecution and increased public education. One element of Project CeaseFire was carried out by the South Carolina Department of Probation, Parole, and Pardon Services. The current study utilized a quasi-experimental design to compare firearm-related incidents among a random sample of offenders under community supervision prior to and after the implementation of the SCDPPPS CeaseFire program. Although incidents involving a firearm were rare, the current results did not indicate a reduction in firearm-related incidents among offenders entering supervision after the SCDPPPS CeaseFire program was implemented. Instead, an increase in firearm incidents was observed after CeaseFire implementation. Possible explanations for the observed results are offered along with limitations to the study and policy implications.     

Selection Bias and Continuous-Time Duration Models: Consequences and a Proposed Solution

This article analyzes the consequences of nonrandom sample selection for continuous-time duration analyses and develops a new estimator to correct for it when necessary. We conduct a series of Monte Carlo analyses that estimate common duration models as well as our proposed duration model with selection. These simulations show that ignoring sample selection issues can lead to biased parameter estimates, including the appearance of (nonexistent) duration dependence. In addition, our proposed estimator is found to be superior in root mean-square error terms when nontrivial amounts of selection are present. Finally, we provide an empirical application of our method by studying whether self-selectivity is a problem for studies of leaders' survival during and following militarized conflicts.     

Elemental Analysis of Variably Contaminated Cremains Using X‐ray Fluorescence Spectrometry

Analyzing and identifying skeletal remains becomes increasingly difficult when remains have been cremated, especially in cases where the cremated material may have been intentionally contaminated with nonskeletal material. This study examined the potential of X‐ray fluorescence spectrometry (XRF) to detect the presence of nonskeletal contaminants in samples of cremains. Eleven samples of cremains were variably combined with concrete mix and analyzed using XRF. Photon counts of elements in each sample were analyzed, and the coefficient of determination (R²) using unweighted linear regression as a function of percent cremains was calculated. Results showed that with changes in the proportion of skeletal material and contaminant, there were significant (R² > 0.90) changes in detected levels of phosphorus, potassium, zinc, aluminum, and sulfur. The use of XRF is concluded to be a valid approach in the identification of the presence of nonskeletal material in potentially contaminated cremains.     

Perceptions and use of videoconferencing in forensic mental health assessments: A survey of evaluators and legal personnel

ABSTRACT

The use of videoconferencing (VC) to conduct forensic mental health assessments (FMHA) is increasing. Yet, little is known about its acceptability among clinicians or legal professionals. In Study 1 (N?=?156), forensic evaluators were asked about their use of VC, reasons for its use, and opinions about the validity, usefulness, ethics, and legality of its use. An estimated one-third of evaluators have used VC in the past. Although evaluators overall expressed moderate concern over the ethics and legality of use, prior experience appeared to mitigate concerns. Younger practitioners were also more open to using VC. Reduced costs for courts was the most frequently endorsed benefit associated with VC, while restricted ability to administer psychological testing and potential technological problems were seen as the biggest disadvantages. In Study 2 (N?=?27), attorneys and judges were surveyed about frequency with which they encounter VC for FMHA and their perceptions about the validity of those assessments. Findings indicated legal personnel expressed rather negative views without having much first-hand experience of VC, including concerns about establishing rapport and technical difficulties. These studies have implications for whether VC will be adopted more frequently in FMHA.     

‘A Nation Reborn’: Right to Law and Right to Life in The Purge Franchise

ABSTRACT

Popular culture matters for helping make sense of our political lives. This article addresses the value of dystopian horror films in challenging narratives about the state. It is situated within broader understandings of popular culture and politics, and specifically within narrative understandings of the state as a performative body. It presents The Purge film franchise as an example of such a challenge to state narratives, and argues that through its distortion of dominant state narratives, the franchise reveals and challenges the intersections of economic and racial inequality in the neoliberal United States. It examines in particular the emergency broadcast featured in all four films, which positions citizens in a relationship with law and life where the right to law conflates the right to life, and argues that the films present an understanding of vulnerability and abandonment that are in some ways already present in the state. It concludes by questioning what, if any, the capacities are for resistance.     

A comprehensive regression tree to estimate body weight from the skeleton

The purpose of this research is to estimate actual body weight (in particular obesity) from the human skeleton. Known individuals (total n=187) were studied from the Bass Collection from the University of Tennessee, Knoxville. This research combines bone density, cross-sectional geometry of the femur and skeletal pathologies. Bone mineral density was calculated for the proximal femur. Three-dimensional bone surface models were created from computed tomographic scans. Cross-sectional geometry of the femur was calculated at five locations along the diaphysis. The pathologies analyzed were heel spurs, diffuse idiopathic skeletal hyperostosis (DISH), and tibial osteoarthritis. The best regression tree model included only four variables. The first split to estimate body weight was the minimum moment of inertia (I(y) ) at the distal femur, the second was midshaft width, then anteroposterior thickness at the proximal slice and the final split was the degree of DISH (SD 17.1-31.0 kg). The ability to estimate body weight from the skeleton is one more useful tool for the osteologist.
