Different assays for hingamine in the study of biological fluids

The authors present a method of hingamine identification in non-biological substances (tablets, powder, syringes) and biological fluids (blood, urine). Isolation was made with chloroform in pH 10. Identification was conducted with thin-layer chromatography, gas chromatography/mass-spectrometry, high-performance liquid chromatography, spectrophotometry in UV region. The quantity was estimated with spectrophotometry in UV region, high-performance liquid chromatography and high-performance thin-layer chromatography. The results of the three methods are comparable.     

Forensic-medical obstetric-gynecological examinations in cases on professional delinquency of medical personnel

We studied the trend in the number of forensic-medical examinations in trials against obstetricians and gynecologists conducted in Primorsky Region in 1997-2005. Most typical defects in obstetric-gynecological care are characterized. These cases are analysed in terms of forensic-medical practice. Detection and forensic-medical analysis of the above defects contribute to optimization of the diagnosis and treatment both in obstetric-gynecological practice and in wide medical practice.     

Mass Murder: Discussing Criminological Perspectives

How do we think about mass murder? While the principle of responsibilityprovides an effective mechanism for the repression of mass murder(notably through Article 25 ICCSt.), analysis of the ‘actingout’ of mass murder by perpetrators requires a criminologicalperspective. Analysis of criminogenic processes, and of genocidallogic, helps us go some way in understanding how perpetrators‘act out’ mass murder. Such an approach also leadsus to identify a long silence in the social sciences: mass murderhas become a legitimate field of social scientific study onlyrecently; it also has the advantage of exposing the shortcomingsof many concepts. This article deals with works focusing on‘mass murder’ and suggests new research paths inthe social sciences.     

Unicorns or Tiger Woods: Are Lie Detection Experts Myths or Rarities? A Response to On Lie Detection “Wizards” by Bond and Uysal

Bond and Uysal (this issue) complain that expert lie detectors identified by O'Sullivan and Ekman (2004) are statistical flukes. They ignore one class of experts we have identified and misrepresent the procedures we use to identify the others. They also question the psychometric validity of the measures and protocol used. Many of their points are addressed in the chapter they criticize. The fruitfulness of the O'Sullivan-Ekman protocol is illustrated with respect to improved identification of expert lie detectors, as well as a replicated pattern of errors made by experts from different professional groups. The statistical arguments offered confuse the theoretical use of the binomial with the empirical use of the normal distribution. Data are provided that may clarify this distinction.     

Comparison of motor oils using high-temperature gas chromatography-mass spectrometry

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.     

Female Perpetrated Dyadic Psychological Aggression Predicts Relapse in a Treatment Sample of Men with Substance Use Disorders

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder (SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention.     

Playing the race card: Making race salient in defence opening and closing statements

Purpose. Researchers have reported that making a Black defendant's race salient reduces White jurors' tendency to find Black defendants guilty ( Sommers & Ellsworth, 2000 ). We examined whether making race salient by including racially salient statements in the defence attorney's opening and closing statements (i.e., ‘playing the race card’) reduced White jurors' racial bias against a Black defendant. Method. We obtained scores on racial attitudes for 151 White college students who participated in an experiment where defendant race (Black, White) and race salience (not salient, salient) were manipulated in a between‐subjects design. Participants read one of four trial stimuli and completed dependent measures. Results. ‘Playing the race card’ reduced White juror racial bias as White jurors' ratings of guilt for Black defendants were significantly lower when the defence attorney's statements included racially salient statements. White juror ratings of guilt for White defendants and Black defendants were not significantly different when race was not made salient. This effect was separate from jurors' level of prejudice (as measured by racial attitudes) as high prejudice participants were more likely than low prejudice participants to find the Black defendant guilty, independent of the race salience manipulation. Conclusion. Our study indicated that an explicit attempt by a defence attorney to ‘play the race card’ was a beneficial trial strategy a defence attorney could use to reduce White jurors' bias towards Black defendants. However, the beneficial effect of such a strategy may not reduce White jurors' bias towards Black defendants for all White jurors.     

Further Validation of the Test of Memory Malingering (TOMM) Trial 1 Performance Validity Index: Examination of False Positives and Convergent Validity

Assessment of performance validity is an essential part of a neuropsychological evaluation, with the inclusion of two or more performance validity tests (PVTs) becoming routine practice. Considering the time to administer multiple tests, there has been some support for use of the Test of Memory Malingering (TOMM) Trial 1 (T1) as an independent, “one and done” PVT. Notably, cutoffs for TOMM T1 need further validation, with an emphasis on minimizing false-positive classifications among those with bona fide cognitive impairment. In a clinically referred sample of 127 veterans, this study examined the role of cognitive impairment in TOMM performance and the utility of a TOMM T1 as an independent PVT. Examinees were administered the TOMM and three additional PVTs as part of a comprehensive neuropsychological battery. Sixty-eight percent of examinees were classified valid (35% of valid examinees were cognitively impaired). TOMM T1?≤?40 had excellent observed sensitivity (83%) and specificity (93%) overall, with minimal false-positive classification. TOMM T1 was also significantly correlated and concordant with other memory-based PVTs. Given score ranges and failure rates for TOMM T1?≤?40 among those with neurological/neurocognitive conditions, scores in the 37–40 range may merit administration of additional TOMM trials to maximize accuracy in identifying valid-cognitively impaired versus noncredible performance. Otherwise, an abbreviated TOMM administration (i.e., only T1) using a cutoff of ≤?40—in conjunction with one or more additional PVTs—may be sufficient for detecting noncredible/invalid test performance in the absence of known or suspected neurological/neurocognitive disorders.
