Assessing the Violent Offending and Violent Victimization Overlap Among Discharged Psychiatric Patients

Prior studies have documented linkages between mental disorder and both offending and victimization. However, few studies have examined the violent offending–violent victimization overlap among mentally disordered individuals and none have examined the factors that are jointly related to their covariation. Here, we assess this overlap during the first ten weeks following hospital discharge among a large sample of psychiatric patients from three large cities. Findings indicate that: (1) violent offending and violent victimization show substantial covariation; (2) although each of the two outcomes were predicted by a few unique risk factors, several risk factors were similarly predictive of both outcomes; and (3) even after adjusting for demographic, clinical, and social risk factors, the correlation between violent offending and violent victimization remained robust. Implications for theory, research, and policy are highlighted.     

Trends in Mortality of the Soviet Population

Two prominent American demographers present an up-to-date study of trends and countertrends in mortality of the Soviet population; discussed are variations (by republic and over time) in life expectancy, infant mortality, and mortality in the working ages. Analyzing trends since 1959, the authors highlight problems relating to the quality and interpretation of pertinent statistical data of Soviet origin. Distinguishing real trends from pseudotrends, they evaluate mortality differences among regions and illustrate a more favorable long-term trend in mortality than suggested by official figures (nonetheless, because of error in official statistics, actual rates are generally higher).

Power,National Security and Transparency: Judicial Decision Making and Social Architecture in the Federal Courts

Even in a democratic society, the need for transparency must be balanced with an important countervailing interest: the occasional, legitimate need for government secrecy. This article, based on an examination of opinions in federal cases dealing with national security and transparency, explores how judges identified the main legal issues presented by a case and the legal factors or mode of legal interpretation used to reach or justify their conclusions. The article concludes that many of these opinions are as much about judges’ attempts to balance the judicial branch's power with the powers of the executive and legislative branches as they are about national security and transparency. Furthermore, the article contends these opinions have created an “architecture of power” that determines how national security information is controlled. The final section also suggests that judges should be mindful of the original architecture of power established by the Constitution and the First Amendment when writing their opinions.     

Saving more than the children: the role of child-focused NGOs in the creation of southern security norms

The past decade has seen the emergence of ‘new critical discourses’ on security that argue for a widening of the term. This article hopes to add to such discussions by specifically examining the position of children and of the ngos that champion their rights in relation to the evolving security discourse in Southern societies. With this in mind, the first section of the article outlines the role of ngos in the contemporary practice of security. This will serve as an introduction to section two, where the activity of ngos vis-à-vis children will be considered. Such activity raises a number of questions with regard to the usefulness of incorporating children into the security discourse specifically, and to the social construction of ‘children’ generally. These will be outlined in section three. Section four argues for children to be considered as inherent to the creation of Southern security norms, while the final section concludes.     

Correlation between saw blade width and kerf width

Most studies of saw marks have focused on morphological characteristics and their utility in identifying saws suspected to have been utilized in cases of criminal dismemberment. The present study examined the extent to which metric analysis may be used to correlate saw blade measurements with minimum kerf widths (MKWs). A sample of 56 partially defleshed white‐tailed deer (Odocoileus virginianus) long bones was utilized as proxy for human remains. The long bones were cut using a variety of commercially available saws, including 11 manual‐powered and 5 mechanical‐powered saws. A total of 496 false start kerfs (FSKs) were created. Two experiments were performed, with the first test examining the MKWs of FSKs produced on specimens that were restrained using a bench vise, while the second test analyzed the MKWs of FSKs produced on minimally restrained specimens. Statistical analysis using Hierarchical Linear Modeling (HLM) indicated a positive relationship between saw blade width (mm) and MKW, with blade width (p < 0.001) and the overall difference between the mechanical‐ and manual‐powered saws (p = 0.029) tested, reaching statistical significance. A comparison of MKWs produced using manual‐powered saws on restrained and minimally restrained bones suggests that restraint condition (p = 0.009) has a statistically significant effect. In comparisons of MKWs to blade widths, the average ratio for mechanical‐powered saws is 18.7% greater than the average ratio for manual‐powered saws. While the mode of the ratios was 1.42, thus supporting the general rule that MKW does not exceed 1.5 times blade width, multiple individual ratios did surpass 1.5.     

Forensic determination of hair deposition time in crime scenes using electron paramagnetic resonance

Several types of biological samples, including hair strands, are found at crime scenes. Apart from the identification of the value and the contributor of the probative evidence, it is important to prove that the time of shedding of hair belonging to a suspect or victim matches the crime window. To this end, to estimate the ex vivo aging of hair, we evaluated time‐dependent changes in melanin‐derived free radicals in blond, brown, and black hairs by using electron paramagnetic resonance spectroscopy (EPR). Hair strands aged under controlled conditions (humidity 40%, temperature 20–22°C, indirect light, with 12/12 hour of light/darkness cycles) showed a time‐dependent decay of melanin‐derived radicals. The half‐life of eumelanin‐derived radicals in hair under our experimental settings was estimated at 22 ± 2 days whereas that of pheomelanin was about 2 days suggesting better stabilization of unpaired electrons by eumelanin. Taken together, this study provides a reference for future forensic studies on determination of degradation of shed hair in a crime scene by following eumelanin radicals by utilizing the non‐invasive, non‐destructive, and highly specific EPR technique.     

Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening at autopsy

Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.     

Identification of furosemide in hair in a post‐mortem case by UHPLC‐MS/MS with guidance on interpretation

Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The prosecutor requested our laboratory to undertake an additional analysis in hair to obtain information about the use of furosemide. A specific method was therefore developed and validated to identify and quantify furosemide in hair by UHPLC‐MS/MS. After decontamination of 30 mg of hair, incubation in acidic condition, extraction with ethyl acetate, the samples were analyzed by UHPLC‐MS/MS. Furosemide was found in the victim's hair at 225 pg/mg. However, it was not possible to interpret this concentration due to the absence of data in the literature. Therefore, the authors performed a controlled study in two parts. In order to establish the basis of interpretation, several volunteers were tested (four after a single 20 mg administration and twenty‐four under daily treatment). The first part indicated that a single dose is not detectable in hair using our method. The second part demonstrated concentrations ranging from 5 to 1110 pg/mg with no correlation between dosage and hair concentrations. The decedent's hair result was interpreted as repeated exposures. In the case of furosemide analysis, hair can provide information about its presence but cannot give information about dosage or frequency of use.
