Designer Psychostimulants in Urine by Liquid Chromatography–Tandem Mass Spectrometry,

Designer psychostimulants are known by recreational drug users to produce a complex array of adrenergic and hallucinogenic effects. Many of these drugs are not targeted during routine toxicology testing and as a consequence, they are rarely reported. The purpose of this study was to develop a procedure for the detection of 15 psychostimulants in urine using liquid chromatography–tandem mass spectrometry (LC‐MS/MS), specifically 2,5‐dimethoxy‐4‐bromophenethylamine (2C‐B), 2,5‐dimethoxy‐4‐chlorophenethylamine (2C‐C), 2,5‐dimethoxy‐4‐methylphenethylamine (2C‐D), 2,5‐dimethoxy‐4‐ethylphenethylamine (2C‐E), 2,5‐dimethoxyphenethylamine (2C‐H), 2,5‐dimethoxy‐4‐iodophenethylamine (2C‐I), 2,5‐dimethoxy‐4‐ethylthiophenethylamine (2C‐T‐2), 2,5‐dimethoxy‐4‐isopropylthiophenethylamine (2C‐T‐4), 2,5‐dimethoxy‐4‐propylthiophenethylamine (2C‐T‐7), 2,5‐dimethoxy‐4‐bromoamphetamine (DOB), 2,5‐dimethoxy‐4‐chloroamphetamine (DOC), 2,5‐dimethoxy‐4‐ethylamphetamine (DOET), 2,5‐dimethoxy‐4‐iodoamphetamine (DOI), 2,5‐dimethoxy‐4‐methylamphetamine (DOM), and 4‐methylthioamphetamine (4‐MTA). Analytical recoveries using solid‐phase extraction were 64–92% and the limit of detection was 0.5 ng/mL for all drugs except 2C‐B (1 ng/mL). The assay was evaluated in terms of analytical recovery, precision, accuracy, linearity, matrix effect, and interferences. The technique allows for the simultaneous detection of 15 psychostimulants at sub‐ng/mL concentrations.     

The Measurand Problem in Breath Alcohol Testing

Proper interpretation of forensic measurements can be critical to the administration of justice. Breath alcohol testing is commonly relied upon to measure the concentration of alcohol in breath or, indirectly, in blood. The concentration sought constitutes the “quantity intended to be measured,” referred to as the measurand. Although breath tests always probe the same physical quantity, their measurand is dictated by statute and varies between jurisdictions. Thus, identical numerical values obtained from tests in disparate jurisdictions may refer to different quantities and may not indicate the relevant statutory measurand. This can lead to misinterpretation of results, referred to as the “measurand problem.” We first illustrate the concept of the measurand. Thereafter, the measurand problem is illustrated through application of Hlastala's breath test paradigm and Gullberg's work on breath test uncertainty. It is shown that where the measurand is not properly accounted for, conclusions based upon breath test evidence are undermined.     

Examining the scope of questionable diagnostic reliability in Sexually Violent Predator (SVP) evaluations

Research has suggested questionable reliability of diagnosing mental abnormality during Sexually Violent Predator (SVP) evaluations, despite this being a necessary requirement for SVP commitment. Findings have been inconsistent across studies, and little is known about the extent of such trends across diagnoses and clinicians. The current study includes data from 375 sex offenders referred for evaluation for SVP commitment in New Jersey. Clinicians (n = 128) rendered a variety of diagnoses, most commonly Pedophilia. Results suggested questionable agreement across paraphilic and non-paraphilic diagnoses, although agreement was fair for diagnoses of Pedophilia. Further analyses of cases (n = 49) involving clinicians receiving a large number of referrals (n = 14) were generally consistent with these findings, with no outlier effect apparent. Findings suggest questionable diagnostic reliability to be a widespread issue in SVP evaluations, present across a variety of diagnoses and across the general body of clinicians involved in evaluations.     

Attitudes toward hiring applicants with mental illness and criminal justice involvement: The impact of education and experience

Individuals with mental health diagnoses, as well as those involved in the criminal justice system, experience a number of barriers in the recovery and reintegration progress, including access to stable, prosocial employment opportunities. Employment for these populations is important for establishing financial security, reducing unstructured leisure time, increasing self-worth, and improving interpersonal skills. However, research has demonstrated that individuals with psychiatric and/or criminal backgrounds may experience stigmatizing attitudes from employers that impede their ability to find adequate work. This study aimed to evaluate stigmatizing beliefs toward hypothetical applicants who indicated a mental health history, a criminal history, or both, as well as the effectiveness of psychoeducation in reducing stigma. Participants consisted of 465 individuals recruited from a large university who completed a series of online questions about a given applicant. Results of this study varied somewhat across measures of employability, but were largely consistent with extant research suggesting that mental illness and criminal justice involvement serve as deterrents when making hiring decisions. Overall, psychoeducation appeared to reduce stigma for hiring decisions when the applicant presented with a criminal history. Unfortunately, similar findings were not revealed when applicants presented with a psychiatric or a psychiatric and criminal history. Implications and limitations of these findings are presented, along with suggestions for future research.     

SWGDAM developmental validation of a 19-locus Y-STR system for forensic casework

A Scientific Working Group on DNA Analysis Methods (SWGDAM) developmental validation study was carried out on two Y-STR multiplex systems (MPI and MPII) that collectively permit the co-amplification of 19 Y-STR markers, including DYS393, DYS392, DYS391, DYS389I, DYS389II, Y-GATA-A7.2 (DYS461), DYS438, DYS385a and DYS385b (MPI); DYS425, DYS388, DYS390, DYS439, DYS434, DYS437, Y-GATA-C.4, Y-GATA-A7.1 (DYS460), Y-GATA-H.4, and DYS 19 (MPII). Performance checks subsequent to PCR parameter optimization indicated that MPI and MPII were suitably reproducible, precise and accurate for forensic use. The sensitivity of the systems was such that a full 19-locus Y-STR profile was obtainable with 150-200 pg of male DNA, and some loci were detectable even with as little as 20-30 pg of input DNA. Primate specificity was demonstrated by the lack of cross-reactivity with a variety of commonly encountered bacterial and animal species, with the single exception of a monomorphic canine product that was outside of the size range of human alleles from any of the 19 loci. Not surprisingly, cross-reactivity was observed with a number of male and female nonhuman primates. Environmentally compromised samples produced full or partial Y-STR profiles. For example, a semen stain exposed to the outdoor elements for six months still gave a 13-locus Y-STR profile. Although a limited number of female DNA artifacts were observed in mixed stains in which the male DNA comprised 1/300 of the total, the full 19-locus male profile was easily discernible. Even at a 1500-to-2000-fold dilution of male DNA with female DNA partial Y-STR profiles were obtained. Furthermore, the potential utility of MPI and MPII for forensic casework is exemplified by their ability to dissect out the male haplotype in a variety of case-type samples, including, inter alia, post-coital vaginal swabs, admixed male and female bloodstains, the nonsperm fraction from a differentially extracted semen stain, and determination of the number of male donors in mixed semen stains.     

Disability, disparate impact, and class actions

Following Title VII's enactment, group-based employment discrimination actions flourished due to disparate impact theory and the class action device. Courts recognized that subordination that defined a group's social identity was also sufficient legally to bind members together, even when relief had to be issued individually. Woven through these cases was a notion of panethnicity that united inherently unrelated groups into a common identity, for example, Asian Americans. Stringent judicial interpretation subsequently eroded both legal frameworks and it has become increasingly difficult to assert collective employment actions, even against discriminatory practices affecting an entire group. This deconstruction has immensely disadvantaged persons with disabilities. Under the Americans with Disabilities Act (ADA), individual employee claims to accommodate specific impairments, such as whether to install ramps or replace computer screens, have all but eclipsed a coherent theory of disability-based disparate impact law. Moreover, the class action device has been virtually nonexistent in disability discrimination employment cases. The absence of collective action has been especially harmful because the realm of the workplace is precisely where group-based remedies are needed most. Specifically, a crucial but overlooked issue in disability integration is the harder-to-reach embedded norms that require job and policy modifications. The Article argues that pandisability theory serves as an analogue to earlier notions of panethnicity and provides an equally compelling heuristic for determining class identity. It shows that pandisability undergirds ADA public service and public accommodation class actions in which individualized remedy assessments have been accepted as part of group-based challenges to social exclusion. The Article also demonstrates that this broader vision of collective action is consistent with the history underlying the class action device. Taking advantage of the relatively blank slate of writing on group-based disability discrimination, it offers an intrepid vision of the ADA's potential for transforming workplace environments. In advocating for a return to an earlier paradigm of collective action in the disability context, the Article also provides some thoughts on challenging race- and sex-based discrimination. Future workplace policies should plan for "all jobs to include some physical activity" unrelated to job qualifications in order to "dissuade unhealthy people from coming to work at Wal-Mart."     

Effects of victim's and defendant's physical attractiveness on the perception of responsibility in an ambiguous domestic violence case

A 2 × 4 × 4 factorial design was used to assess the effects of physical attractiveness in a domestic violence case. The attractiveness of both the defendant and victim were varied along four levels. Subjects were asked to read a domestic violence scenario where pictures of the defendant and victim were varied according their physical attractiveness. Results showed no significant effect of physical attractiveness in a juridic decision-making process in domestic violence. However, there were significant differences between male and female subjects in the sentencing of the defendant. This difference did not hold true for finding the defendant guilty or not guilty.     

GC-MS of ignitable liquids using solvent-desorbed SPME for automated analysis

Solid-phase microextraction (SPME) is well documented with respect to its convenience and applicability to sampling volatiles. Nonetheless, fire debris analysts have yet to widely adopt SPME as a viable extraction technique, although several fire debris studies have demonstrated the utility of SPME coupled with gas chromatography-mass spectrometry (GC-MS) to identify ignitable liquids. This work considers the expansion of SPME sampling from the customary thermal desorption mode to solvent-based analyte desorption for the analysis of ignitable residues. SPME extraction fibers are desorbed in 30 microL of nonaqueous solvent to yield a solution amenable to conventional GC-MS analysis with standard autosampler apparatus. This approach retains the advantages of convenience and sampling time associated with thermal desorption while simultaneously improving the flexibility and throughput of the method. Based on sampling results for three ignitable liquids (gasoline, kerosene, anddiesel fuel) in direct comparisons with the widely used activated charcoal strip (ACS) method this methodology appears to be a viable alternative to the routinely used ACS method.
