Having a Bad Month: General Versus Specific Effects of Stress on Crime

We examine whether particular types of stress are related to particular types of crime or whether all types of stress are related to all types of crime. Our estimates are based on analyses of within-individual change over a 36 month period among recently incarcerated offenders. We find that assault is most strongly related to family stress, suggesting that conflicts between family members lead to assault. Economic crimes (property crimes and selling illicit drugs) are most clearly related to financial stress, suggesting that these crimes often reflect attempts to resolve financial problems. On the other hand, crime is generally unrelated to stress from illness/injury, death, and work. The results support the idea that criminal behavior is a focused response to specific types of problems rather than a general response to stress. They are more consistent with explanations that focus on perceived rewards and costs (e.g., the rational-choice approach) than with explanations that portray negative affect as a generalized impetus toward violence or crime (e.g., frustration aggression approaches).     

The role of inspection sequence in compliance with the US Occupational Safety and Health Administration's (OSHA) standards: Interpretations and implications

We examined the Occupational Safety and Health Administration's (OSHA) inspections in the US to identify the effects of repeated inspections and the time between inspections on non-compliance. Our sample included 549,398 inspections conducted from 1972 through 2006 in manufacturing plants in the 29 states where federal OSHA enforces the law. We controlled for inspection type, industry, establishment size, and year. The number of total violations cited fell by 28%–48% from the first to the second inspection; after that, the numbers declined much more slowly. These effects were found in every one of the four sub-periods examined. The number of violations cited increased with each additional year since the prior inspection after controlling for other variables; however, the increases were small, totaling approximately 15% over five years. OSHA should probably give higher priority to first time inspections than to repeated inspections. The current requirement that at least two years elapse between planned inspections should probably be lengthened.     

Qualitative Evaluation of a High School Mental Health Program

Expanded school mental health (ESMH) programs offer a comprehensive range of mental health services (evaluation, therapy, case management) to youth in special and regular education. Research is needed to document that these programs are in fact providing quality care to youth and leading to enhanced outcomes. In this exploratory study, focus groups were conducted with high school students receiving mental health services and students not receiving services, therapists, parents, administrators, and health care staff to gauge the quality and effectiveness of an ESMH program. It was difficult to schedule parents for group sessions; thus, interviews also were conducted with this group. Focus groups and interviews were effective methods for understanding strengths, areas for improvement, and outcomes for our ESMH program. Participants reported that therapy served as a protective factor, enhancing physical and mental health and reducing risk for teenagers. Ideas for improving clinical practice were developed from study results.     

Detection of sequence variation in the HVII region of the human mitochondrial genome in 689 individuals using immobilized sequence-specific oligonucleotide probes

We have developed a rapid, immobilized probe-based assay for the detection of sequence variation in the hypervariable segment II (HVII) of the mitochondrial DNA (mtDNA) control region. Using a panel of 17 sequence-specific oligonucleotide (SSO) probes immobilized on nylon membrane strips, we typed 689 individuals from four population groups. The genetic diversity value for each population was calculated from the frequency data, and the frequencies of distinct "mitotypes" in each group were determined. We performed DNA sequence analysis of 129 samples to characterize the sequences associated with "blanks" (absence of probe signals) and weak probe signals. Out of 689 samples, we observed five heteroplasmic samples (excluding the variable C-stretch beginning at position 303) using the immobilized SSO probe panel. The SSO probe strips were used for the analysis of shed hairs and bloodstains from several criminal cases in Sweden, one of which is described here. We conclude that this mtDNA typing system is useful for human identification and significantly decreases casework turnaround time.     

Lessons learned from large-scale comparative dental analysis following the South Asian tsunami of 2004

The aim of this study was to examine the quality of the ante-(AM) and postmortem (PM) dental data that were submitted for entry into the PLASS data system in Phuket, Thailand, following the Boxing Day (December 26) Tsunami, 2004. The investigators were two forensic odontologists who were part of the New Zealand Disaster Victim Identification team that worked at Wat Yang Yao morgue and at the Information Management Center in Phuket. Our findings underline the usefulness of dental data in human identification, but point to a number of significant sources of error. Of the 78 PM records received, only 68% of radiographs and 49% of photos confirmed the accompanying dental charting. This underlines the value, particularly of photographs of the dental arches, in quality control. It also points to a large error component, which may have been due to inexperience of the operators, fatigue, poor conditions in the temporary morgue, or the problem of tooth-colored fillings. Of the 106 AM records received, 62% were of unacceptable quality and 64% were either not accompanied by radiographs or had poor quality radiographs. These results indicate that AM data collection ideally needs to be collated and checked by a forensically trained dentist(s) in the country of origin.     

Combating child homicide: preventive policing for the new millennium

High-profile media coverage of crimes against children has heightened public awareness of critical child safety needs and issues. However, numerous research studies in the area of child homicide have illustrated the importance of the power of science to correct false perceptions and misinformation, improving how to best serve and protect our children. Age-based analyses of childhood crime patterns have vastly improved how law enforcement and social service practitioners identify, investigate, and resolve child victimization cases. Future protective efforts must involve multiagency and multidisciplinary collaboration. Law enforcement, social service clinicians, educators, and academicians should jointly develop and implement pragmatic and effective prevention, detection, and resolution programs and policies.

Empire, Region, World: the International Context of Australian Foreign Policy since 1939

What have been the most important factors in international relations for Australian foreign‐policymakers over the last sixty years? Five broad themes stand out: the end of empire; Cold War dependency; the changing nature of security; economic development; and race and national identity. Cumulatively, and often in intertwined ways, these themes have amounted to little short of a revolution in Australia's place in the world since the Second World War. The challenges facing Australians have, as a result, been considerable. The international context in which Liberals have made foreign policy has been reshaping Australia as it has been reshaping the external environment.
