Excellence in Psychological Injury and Law: Book Review of Motor Vehicle Collisions by Duckworth, Iezzi, and O’Donohue (2008)

In several ways, the book on motor vehicle collisions by Duckworth, Iezzi, and O’Donohue (2008) breaks new ground and should be considered a must-read for workers in the area of psychological injury and law. The editors have assembled a team of expert authors who have cogently analyzed the scientific evidence in the area of motor vehicle collisions and their aftermath, while calling for more research. The book is replete with information that will help practitioners understand and deal with cases involving conditions such as chronic pain, posttraumatic stress, and traumatic brain injury. Practitioners will learn about complications in such cases, including threats to validity and legal aspects. The inclusion of chapters from a medical perspective is a welcome innovation. The book is only lacking in that, although assessment is considered throughout, chapters specifically addressing this topic are not included. The book review concludes that the Motor vehicle collisions book by Duckworth et al. should be included as part of the growing list of excellent resources in the area of psychological injury and law.     

Policy Forum: Studying Eyewitness Investigations in the Field

This article considers methodological issues arising from recent efforts to provide field tests of eyewitness identification procedures. We focus in particular on a field study (Mecklenburg 2006) that examined the “double blind, sequential” technique, and consider the implications of an acknowledged methodological confound in the study. We explain why the confound has severe consequences for assessing the real-world implications of this study.     

Using State Child Labor Laws to Identify the Causal Effect of Youth Employment on Deviant Behavior and Academic Achievement

On the basis of prior research findings that employed youth, and especially intensively employed youth, have higher rates of delinquent behavior and lower academic achievement, scholars have called for limits on the maximum number of hours per week that teenagers are allowed to work. We use the National Longitudinal Survey of Youth 1997 to assess the claim that employment and work hours are causally related to adolescent problem behavior. We utilize a change model with age-graded child labor laws governing the number of hours per week allowed during the school year as instrumental variables. We find that these work laws lead to additional number of hours worked by youth, which then lead to increased high school dropout but decreased delinquency. Although counterintuitive, this result is consistent with existing evidence about the effect of employment on crime for adults and the impact of dropout on youth crime.

Psychotherapy for Psychological Injury: A Biopsychosocial and Forensic Perspective

This article reviews the predominant psychological approaches to therapy and other treatments in the field of psychological injury. Mostly, they concern cognitive behavior therapy and its variants. However, because of the simultaneous physical injuries or physiological effects that accompany these types of injury, practitioners should adopt an integrated biopsychosocial approach in treatment (Sperry, L., Treatment of chronic medical conditions: Cognitive-behavioral therapy strategies and integrative treatment protocols. Washington, DC: American Psychological Association, 2006; Treatment of chronic medical conditions: Cognitive-behavioral therapy strategies and integrative treatment protocols. Washington, DC: American Psychological Association, 2009). The paper presents a componential model of therapy that integrates the cognitive-behavioral, biopsychosocial, and forensic approaches. More research needs to be undertaken that takes into account the difficulties of conducting therapy with individuals who are expressing psychological injury. This will help in the quest to formulate evidence-based but flexible practice guidelines. The paper concludes with a model that may serve to scaffold the numerous psychotherapies that are available into a more coherent framework.     

Do drug users use less alcohol than non-drug users? A comparison of ethyl glucuronide concentrations in hair between the two groups in medico-legal cases

Two groups were selected from the remainder of hair samples that had been tested for drugs at TrichoTech for medico-legal cases: samples that tested negative (drug-negative group; N=42, age 33.4+/-7.2 years) and samples that tested positive for drugs (drug-positive group; N=57, age 32.5+/-8.8 years). A rapid, simple method to detect the ethanol metabolite, ethyl glucuronide (EtG) in hair has been developed. The hair samples were sectioned, and then submitted to overnight sonication in water. Samples then underwent SPE using anion exchange cartridges, followed by derivatisation with N,O-bis[trimethylsilyl]trifluoroacetamide (BSTFA), before confirmation by GC-MS/MS. The assay produced excellent linearity and sensitivity over the calibration range 0.02-1.0 ng/mg, assuming a 10 mg hair sample. The mean age of the two groups was not statistically different (p=0.575, Student t-test), indicating a homogeneous group. Twelve of the 57 (21.0%) hair samples of the drug-positive group tested positive for EtG, and 17 of the 42 (40.5%) hair samples of the drug-negative group tested positive for EtG. The mean concentration of EtG in the drug-positive group was 0.011 ng/mg compared to 0.107 ng/mg in the drug-negative group. When the full results of this study were subjected to statistical analysis it was shown that EtG levels in the drug-negative group were statistically higher than those found in the drug-positive group (p<0.05). This preliminary finding may be of use in the study of addiction and adds valuable data to previous studies regarding the use of EtG as a valuable marker for alcohol levels in hair.     

The relationship between serial sexual murder and autoerotic asphyxiation

This case series documents and examines the association between autoerotic asphyxiation, sadomasochism, and serial sexual murderers. Autoerotic asphyxiation, along with other paraphilias found in this population, is reviewed. Five cases of serial sexual killers who engaged in autoerotic asphyxiation were identified worldwide: four from the United States and one from Russia. Case reports for each are provided. All (100%) were found to have sexual sadism in addition to autoerotic asphyxiation. Furthermore, two (40%) had bondage fetishism, and two (40%) had transvestic fetishism, consistent with these paraphilias co-occurring in those with autoerotic asphyxiation. Overall the group averaged 4.0 lifetime paraphilias. Some possible relationships were observed between the offenders' paraphilic orientation and their modus operandi, e.g., all of these serial killers strangled victims-suggesting an association between their sadistic and asphyxiative paraphilic interests. The overlap of seemingly polar opposite paraphilias in this sample--sexual sadism and autoerotic asphyxiation--is explored from a historical and clinical perspective. Multiple commonalities shared between these five offenders and serial sexual murderers in general are addressed. A primary limitation of this study is its small sample size and empirical basis; the results may not be generalizable beyond the sample. The findings from this study support the supposition that crime scene behaviors often reflect paraphilic disturbances in those who commit serial sexual homicides.     

Validation and casework application of a Y chromosome specific STR multiplex

A series of validation experiments was performed for a Y chromosome specific STR multiplex system following the suggestions made by the Technical Working Group DNA Analysis Methods (TWGDAM). The multiplex PCR products were detected on Perkin-Elmer 373 and 377 automated sequencers using two labeling colors. No problems regarding the stability, robustness and sensitivity of the Y STR multiplex were observed. Mixture studies revealed a cut off rate similar to autosomal STRs for mixtures of male DNAs and no interference of any female admixture. The comparison of the Y STR results to the autosomal typing results for 56 nonprobative semen stains and swabs, showed a slightly higher success rate in detecting the semen donor’s alleles for the Y STR multiplex. Two examples are shown to illustrate the usefulness of Y STR typing for DNA mixtures. In one case the Y STR results confirmed an isolated exclusion; in the other case, the interpretation of a mixture was clarified since the Y STR results proved the presence of DNA from at least two semen donors. Y STR typing is a valuable addition to the forensic DNA testing panel.     

Regimes on Pillars: Alternative Welfare State Logics and Dynamics

Social welfare arrangements represent the conjunction of the twin logics of regimes and pillars. Regimes describe who receives the benefits and on what conditions; pillars describe who pays for and who provides the benefits. There are historical associations and '"natural" affinities' between certain regimes and certain pillars. But there is also scope for novel combinations and recombinations. Many contemporary welfare state reforms are best conceptualized in terms of shifting the mix of pillars and blurring regimes.
