Windows of Opportunity: Window Subseries Empirical Variance Estimators in International Relations

We show that temporal, spatial, and dyadic dependencies amongobservations complicate the estimation of covariance structuresin panel databases. Ignoring these dependencies results in covarianceestimates that are often too small and inferences that may bemore confident about empirical patterns than is justified bythe data. In this article, we detail the development of a nonparametricapproach, window subseries empirical variance estimators (WSEV),that can more fully capture the impact of these dependencieson the covariance structure. We illustrate this approach ina simulation as well as with a statistical model of internationalconflict similar to many applications in the international relationsliterature.     

Suspicious circumstances on discovery of the cadaver

The authors report on three autopsy cases in which the findings at the death scene gave rise to the suspect of non-natural, in two cases even violent causes of death. The medico-legal and criminalistic investigations led to surprising results: Death was due to acute intoxication with narcotics, supposed delirium tremens and a suicide attempt in the presence of bronchopneumonia. External force was ruled out in all three fatalities by cooperative work of police investigators and forensic medicine.     

Driver and front seat passenger fatalities associated with air bag deployment. Part 2: A review of injury patterns and investigative issues

Assessment of the role of air bag deployment in injury causation in a crash of any severity requires analysis of occupant, vehicle, and impact data. The potential injurious role of an air bag is independent of crash severity and is more obvious in minor collisions, particularly those involving "out-of-position" occupants. Factors such as occupant height and other constitutional and medical factors, intoxication, age, type, and proper use of other restraint systems, pre-impact braking and multiple impacts can contribute to an occupant being "out-of-position." Two injury mechanisms are described in out-of-position occupants: "punch-out" when the individual covers the air bag module before deployment and "membrane-force" when the occupant contacts a partly deployed air bag. Each mechanism is associated with injury patterns. In adults, "punch-out" can cause thoraco-abdominal trauma and "membrane-force" loading can lead to craniocervical injury. This can also occur in short-statured occupants including children subjected to both types of loading. In more severe collisions, other factors, e.g., intrusion, steering column and seatbelt loading and other occupant compartment contacts, can contribute to trauma.     

Hemopericardium caused by endocarditis ulcerosa: an unusual cause of sudden death in adolescence

The authors report on the case of a 18-year-old student who died suddenly and unexpectedly of a pericardial tamponade after perforated ulcer-polypous endocarditis of the aortic valve. The detection of aerococcus urinae--which usually causes urinary tract infection--on the inflamed aortic valve demonstrates an unusual pathogenetic chain linking complexes of findings in the urogenital system and the heart.     

Shame and guilt in child sexual offenders

In this article, the authors build on previous discussions of the possible role of shame and guilt in sexual offending. They review the general psychological literature on shame and guilt and conclude that the distinction between internal and external shame is an important one in considering sexual offenders. The effects of shame and guilt on victim empathy and relapse are discussed, and it is proposed that the phenomena of shame and guilt have implications for treatment beyond those identified in previous studies. Shame is a salient feature in the initial presentation of many sexual offenders against children. Furthermore, aspects of the treatment of sexual offenders can be characterized as a shift from shame toward guilt. Implications of shame and guilt for treatment of sexual offenders are described.     

Assisted suicide and human rights

The case of R (Pretty) v. Director of Public Prosecutions, gave the House of Lords the opportunity to comment on the issues surrounding the application of the European Convention on Human Rights to the crime of assisted suicide in the case of the terminally ill. A conservative approach was taken in relation to both this issue and indeed in relation to the possibilities of judicial control of the Law Officers of the Crown.     

Fatal child abuse-maltreatment syndrome. A retrospective study in Ontario,Canada, 1990-1995

Child death due to repeated episodes of physical assault or neglect has been termed the child abuse-maltreatment syndrome (CAMS). We characterized the injuries in a series of fatally abused or maltreated child to delineate objective diagnostic criteria for the CAMS for use by clinicians and pathologists. All deaths (age <17 years) investigated by the Office of the Chief Coroner for Ontario, Canada during the time period 1990-1995 were reviewed. Cases of CAMS were defined as death due to lethal recent injury or malnutrition in the presence of significant old (healing or healed) injuries indicative of repeated episode of inflicted trauma. The nature and frequency of the various injuries was determined. The frequency of the shaken baby syndrome, and the types and frequency of ano-genital injuries were also studied. Twenty-one cases of fatal CAMS were found in the study period. Most cases had significant recent head injury with intra-cranial hemorrhage (71%). Other significant recent injuries commonly observed included blunt injuries of the skin and soft tissues (67%), blunt abdominal trauma with visceral injuries (14%), and fractures (18%). Eight cases (38%) fulfilled accepted criteria for the shaken baby syndrome. Many children with fatal head injuries had evidence of older head trauma (38% of all cases). A significant minority of cases had evidence of malnutrition due to neglect (10%) or ongoing ano-genital injuries (10%). Most cases of child homicides due to repeated episodes of abuse or maltreatment involve head trauma including shaken baby syndrome. Fractures of long bone and ribs, the classical markers of child abuse, were relatively infrequent compared with head injury. A proportion of cases had ano-genital injuries due to repeated sexual abuse or punitive maltreatment. All clinicians and pathologists must recognize the wide spectrum of injuries in child abuse to ultimate protect the victim or other children in an at-risk situation.
