Age structure and crime rates: The conflicting evidence

Because arrest rates are especially high for teenagers and young adults, criminologists have long contended that age structure changes affect crime trends. In recent years, however, this belief has been drawn into question because crime has not declined even though high-crime age groups have shrunk. We argue that the age/crime relationship is probably exaggerated because the high arrest rates for younger persons are due partly to their lesser ability to escape arrest, younger persons commit more group crime, and the age structure of victims should be taken into account. We then review 90 studies that regress crime rates on age structure; only a small minority consistently finds significant relationships. Because of methodological problems in this research, one cannot conclude that the age/crime relationship does not exist, but the weight of evidence shows that forecasts based on demographic trends are not likely to be helpful.     

Changing views of jury power

This article highlights the major events and empirical research in the continuing debate over the power and competence of the jury in civil and criminal trials. The concept ofjury nullification, the power of the jury to return a verdict based upon their moral conscience despite the evidence and the law, is used as a convenient filter to discuss the legal and behavioral assumptions about jury power and performance. The legal, historical, and even behavioral contexts reflect a bipolar theme in the level of trust Americans have exhibited towards the jury system. One pole reflects the notion that juries lack predictability and rationality in their verdicts and are moved by emotional concerns. Antipodally, juries have been thought to reflect an historical competence at applying common sense notions of equity and rationality to conflicted and ambiguous cases. This article traces the history of these two views of jury power and competence. A critical review of the empirical research that may inform the debate about the jury's competence in both criminal and civil arenas is provided.     

Psychology's influence on constitutional interpretation

When organized psychology files amicus briefs with the Supreme Court and other courts, it does so for a variety of reasons and seeks to advance a number of policy objectives. The thesis of this article is that pursuit of some of those objectives is improper and that their pursuit threatens to defeat other objectives. Psychology's expertise is not in constitutional analysis; it is in the study of human behavior. As a practical matter, to pretend to do the former is to weaken our effectiveness in describing the latter. In public interest cases, when acting as a true friend of the court, APA's obligation is to share with the court what empirical research and theory tell us about human behavior, and not to argue for any particular outcome of the case before the court.     

Bizarre impalement fatalities--where is the implement?

Two fatalities due to unusual impalement injuries are reported. (1) A large branch broken off during a storm had entered a passing car and perforated the chest of the driver and the back of the seat. The chest organs were grossly lacerated. The car was subsequently stopped by another tree and this second impact removed the wood from the body. (2) A man suffered anorectal impalement by the leg of a stool turned upside down. He had introduced one stool leg into his anus for sexual stimulation and fell onto it. This resulted in a wound channel 36 cm long including perforation of the rectum, urinary bladder, mesentery, transverse mesocolon and liver. Before autopsy, the mode of death was unclear because the man had removed the stool leg himself, his wife had hidden the stool from the scene, and there were no relevant external injuries. In both cases, a reliable reconstruction required investigation of the scene and consideration of extremely unlikely circumstances or of bizarre human activities.     

HIV study among pregnant Aboriginal women raises concerns

An unlinked HIV seroprevalence study among pregnant Aboriginal women in BC reveals an alarming trend and raises ethical questions about certain types of research in Aboriginal communities.     

The epidemiology of female rape victims who seek immediate medical care: temporal trends in the incidence of sexual assault and acquaintance rape

Women who seek medical care following sexual assault are usually evaluated and treated in an emergency department (ED). Therefore, EDs can be an important source of sexual assault surveillance data. The authors compared the incidence of sexual assault presenting for emergency care in a single county during July to November of 1974 and 1991. Participants included all female sexual assault victims aged 14 and older who presented for ED evaluation. Treating physicians prospectively collected data using standardized forms. The z statistic was used to compare sexual assault incidence. There was a 60% increase in the incidence of sexual assault victims presenting for emergency care in 1991 compared to 1974, primarily due to an increase in the incidence of women presenting to the ED after rapes by known assailants. In contrast, the annual incidence of reported stranger assaults was similar in the two study years.

Medical professionals convicted of accessing child pornography--presumptive lifetime prohibition on paediatric practice? Health Care Complaints Commission v Wingate

Health Care Complaints Commission v Wingate [2007] NSWCA 326 concerns an appeal from the New South Wales Medical Tribunal regarding its findings on professional misconduct outside the practice of medicine in relation to a doctor convicted of possessing child pornography. The latest in a number of cases on this issue in Australia, it highlights the complexity of such decisions before medical tribunals and boards, as well as the diversity of approaches taken. Considering both this case and the recent Medical Practitioners Board of Victoria case of Re Stephanopoulos [2006] MPBV 12, this column argues that Australian tribunals and medical boards may not yet have achieved the right balance here in terms of protecting public safety and the reputation of the profession as a whole. It makes the case for a position statement from Australian professional bodies to create a presumption of a lifetime prohibition on paediatric practice after a medical professional has been convicted of accessing child pornography.     

Hair analysis for cocaine: Factors in laboratory contamination studies and their relevance to proficiency sample preparation and hair testing practices

Hair samples were contaminated by rubbing with cocaine (COC) followed by sweat application, multiple shampoo treatments and storage. The samples were then washed with isopropanol for 15 min, followed by sequential aqueous washes totaling 3.5 h. The amount of drug in the last wash was used to calculate a wash criterion to determine whether samples were positive due to use or contamination. Analyses of cocaine and metabolites were done by LC/MS/MS. These procedures were applied to samples produced by a U.S. government-sponsored cooperative study, in which this laboratory participated, and to samples in a parallel in-house study. All contaminated samples in both studies were correctly identified as contaminated by cutoff, benzoylecgonine (BE) presence, BE ratio, and/or the wash criterion. A method for determining hair porosity was applied to samples in both studies, and porosity characteristics of hair are discussed as they relate to experimental and real-world contamination of hair, preparation of proficiency survey samples, and analysis of unknown hair samples.
