Functioning and Effectiveness of Electronic Control Devices Such as the TASER® M‐ and X‐Series: A Review of the Current Literature

Abstract: Conducted electrical weapons (CEWs) such as the TASER^® M‐ and X‐series deliver short high‐voltage, low‐current energy pulses to temporarily paralyze a person by causing electrical interruption of the body’s normal energy pulses. Despite many scientific publications, which classify the health risks of an appropriate use of the TASER device as minor, there still is a continuous uncertainty about possible side effects with human application. Based on a literature search of the National Library of Medicine’s MEDLINE database’s PubMed system of current publications, the following article describes the mechanisms by which the device operates and discusses possible pathophysiological consequences. The majority of current human literature has not found evidence of clinical relevant pathophysiological effects during and after an exposure of professionally applied CEWs. However, to be able to exclude possible health risks, a medical checkup of people who have been exposed to CEWs is essential.     

A search for obligatory paternal alleles in a DNA database to find an alleged rapist in a fatherless paternity case

Abstract: A sexual assault case resulted in a pregnancy, which was subsequently aborted. The alleged father of the fetus was unknown. Maternal and fetal types were obtained using the 11‐locus AmpF?STR^® SGM Plus^® kit. The national DNA database was searched for the paternal obligatory alleles and detected two suspects who could not be excluded as father of the male fetus. Additional typing using the AmpF?STR^® Minifiler^? kit, containing three additional autosomal loci, was not sufficient to exclude either suspect. Subsequent typing using the PowerPlex^® 16, containing four additional loci, and Y‐Filer^? kits resulted in excluding one suspect. Searching a database for paternal obligatory alleles can be fruitful, but is fraught with possible false positive results so that finding a match must be taken as only preliminary evidence.     

Development of a rapid, 96-well alkaline based differential DNA extraction method for sexual assault evidence

We present a rapid alkaline lysis procedure for the extraction of DNA from sexual assault evidence that generates purified sperm fraction extracts that yield STR typing results similar to those obtained from the traditional organic/dithiothreitol differential extraction. Specifically, a sodium hydroxide based differential extraction method has been developed in a single-tube format and further optimized in a 96-well format. The method yields purified extracts from a small sample set (∼2-6 swabs) in approximately 2 h and from a larger sample set (up to 96 swabs) in approximately 4 h. While conventional differential extraction methods require vigorous sample manipulation to remove the spermatozoa from the substrate, the method described here exploits the propensity of sperm to adhere to a substrate and does not require any manipulation of the substrate after it is sampled. For swabs, sample handling is minimized by employing a process where the tip of the swab, including the shaft, is transferred to the appropriate vessel eliminating the need for potentially hazardous scalpels to separate the swab material from the shaft. The absence of multiple handling steps allows the process to be semi-automated, however the procedure as described here does not require use of a robotic system. This method may provide forensic laboratories a cost-effective tool for the eradication of backlogs of sexual assault evidence, and more timely service to their client agencies. In addition, we have demonstrated that a modification of the procedure can be used to retrieve residual sperm-cell DNA from previously extracted swabs.     

Sexual Revictimization Among College Women: A Review Through an Ecological Lens

This paper reviews factors at the individual, microsystem, meso/exosystem, and macrosystem levels that contribute to sexual revictimization among college women. Potential implications for reducing sexual revictimization on campuses via multilevel targeting of interventions is then discussed. This review reveals that despite a need for additional work examining the influence of multiple interacting factors contributing to revictimization, extant work offers insights as to how colleges can develop comprehensive programs to reduce sexual revictimization. Such programming would not only improve institutional responses to sexual violence, but also serve as a model for reducing general cultural acceptance of the perpetration of sexual assault.     

Differentiation of vaginal cells from epidermal cells using morphological and autofluorescence properties: Implications for sexual assault casework involving digital penetration

This work explores morphological and autofluorescence differences between vaginal and epidermal cells detectable through Imaging Flow Cytometry (IFC), a non-destructive, high-throughput technique. These differences were used to build a predictive framework for classifying unknown cells as originating from vaginal or epidermal tissue, which was tested on hand swabbings with and without digital penetration. Many more cells possessing a vaginal signature (median posterior probability ≥0.90) were detected in digital penetration samples than control hand swabbings. Minimum interpretation thresholds were developed to minimize/eliminate false positives; these thresholds were also effective when screening licked hands, indicating the potential utility of this method for a variety of biological mixture types and depositional events relevant to forensic casework.     

A Monte Carlo simulation and sensitivity cost benefit analysis for use of nylon 4N6FLOQSwabs®

Forensic genetic laboratories are challenged with implementing innovation even if the benefits to operational performance are well demonstrated often because of internal budget constraints. A prospective cost–benefit analysis (CBA) could support justification for an increased budget by effectively demonstrating in a system-based approach the relatively small cost of increasing a laboratory budget can substantially reduce costs to society (both qualitatively and monetarily). A Monte Carlo simulation and sensitivity CBA was performed using a more expensive swab (i.e., nylon 4N6FLOQSwabs®) compared with a less costly cotton swab. Ranges of input values and tangible and intangible benefits were considered. The outcome is that the relatively small increased cost of using a nylon swab pales compared with the potential tangible and intangible benefits to the overall system. This approach provides a sounder basis for requesting additional funds to support implementation of technologies and better approximates realistic situations while accommodating uncertainty of input values.     

Liberating Discretion: The Effect of Rape Myth Factors on Prosecutors’ Decisions to Charge Suspects in Penetrative and Non-Penetrative Sex Offenses

Abstract

In sexual assault cases, prosecutorial charging decisions may be influenced by legal factors like offense seriousness and convictability and extralegal rape myths. We use data on sexual assaults in Los Angeles, to test for the effects of victim behavior, victim credibility, and “real rape” stereotypes on the decision to file charges. We also test the liberation hypothesis, examining whether rape myths influence the charge decision more in less serious nonpenetrative cases then in penetrative cases. Results show that victim credibility and behavior, but not consistency with real rape stereotypes, affect charging decisions, even after controlling for legally relevant factors, and they influence prosecutors’ charging decisions equally in penetrative and nonpenetrative cases. Rape myths also influence the charging decision indirectly via victim cooperation. We conclude that rape myths are incorporated into the criminal justice system’s definition of and response to sexual violence, so cannot be addressed by changing case screening policies.     

Estimating Crime Laboratory Efficiency in the Testing of Sexual Assault Kits,

Over the past decade, the large numbers of untested sexual assault kits (SAKs) have been highlighted as a systematic problem that jeopardizes or delays justice for victims. Considering the benefits of testing SAKs, researchers have worked to shed light on why sexual assault evidence has not been effectively submitted to and processed by crime laboratories. Missing from this discourse has been an understanding of the types of practices or qualities that encourage efficiency in the testing of SAKs in crime laboratories. We analyzed results of a national survey administered to all publicly funded state and local crime laboratories (N = 132 respondents) to provide critical information about (i) the extent to which laboratories are testing all of the SAKs possible given the resources they have available; and (ii) the impact that staffing, equipment, policies, and other practices have on SAK testing efficiency. We find that the average laboratory tests only about 69% of the SAKs possible given the resources available to them. However, although technical inefficiencies explain a large proportion of the number of untested SAKs, the accumulation of untested SAKs must also be attributed to laboratories having insufficient resources (e.g., too few forensic analysts). Moreover, results from stochastic frontier models show that doubling the number of forensic analysts in the typical laboratory would allow them to expand their SAK testing capacity by nearly 50%. Implications of these findings are discussed as they relate to the prioritization of resources for crime laboratories, which often operate under strict budgetary realities.     

“Victim Refuses to Cooperate”: A Focal Concerns Analysis of Victim Cooperation in Sexual Assault Cases

Research suggests that victim cooperation is a strong predictor of arrest and prosecution in sexual assault cases. Relatively little research has focused on identifying the factors that shape the decision to cooperate and the research that does exist is largely atheoretical. We address these gaps by examining victim cooperation using a revised version of the focal concerns perspective. We use data on cases reported to law enforcement agencies in Los Angeles to estimate models using factors situated within three victim focal concerns—crime seriousness, costs of cooperation, and likelihood of conviction—for three stages of the case process. We supplement these results with qualitative data from police reports regarding the reasons why victims refused to cooperate. The findings of this study provide initial support for the theoretical development of victim cooperation using the focal concerns perspective and provide potential guidance to criminal justice practitioners on how to increase victim cooperation.     

Study in blue: trauma,affect, event

As contemporary student activists in the United States embrace a vocabulary of trauma and microaggressions, some critics on the left consider this a depoliticizing move symptomatic of the university’s growing thralldom to neoliberalism. The author argues that such criticism neglects how talk of trauma and microaggressions attempts to affectively manage structural violence’s failure to manifest in the form of discrete, identifiable, and extraordinary events. To illustrate this, she turns to the poetry of Claudia Rankine and the performance art of Emma Sulkowicz as aesthetic treatments of racial microaggression and sexual trauma, respectively. Rankine’s and Sulkowicz’s works belong to an emergent genre the author calls the coincidence report, in which subjects with no proof of structural violence except for their own feelings must cope with what happens when an event doesn’t. Ultimately, both artists sideline attempts to reconstruct the event in favor of redistributing specific affects throughout their respective publics. In both cases, these affects are blue – that is, depressive (Rankine) and obscene (Sulkowicz). Subjects in the blue find themselves ambivalently attached to living politically in the shadow of an event even as they detach from the fantasy that political life is less disappointing, depressing, or deflating than it actually is.
