Unusual hanging deaths

We describe the circumstances and medical findings of four unusual hanging deaths. In brief, the unusual features are tracheostomy, delayed death, self-mutilation combined with severe neck injury caused by lengthy drop, and homicidal hanging in a young girl.     

Shotcup petal abrasions in close range .410-caliber shotgun injuries

Shotcup petal abrasions centered around a shotgun wound of entrance are generally thought to occur at a range of 30 to 90 cm. A suicidal .410-caliber shotgun injury of the right eye is described in which typical petal abrasions were noted around the entrance wound. However, significant soot deposition around the wound suggested that the range of fire was less than 30 cm and perhaps closer to 15 cm. Test-firing of the weapon and ammunition used by the decedent showed some spread of the shotcup petals at a range of 7.5 cm, progressing to maximum spread at 30 to 52.5 cm. Further testing with other .410 ammunition, containing shotcups, confirmed the spread of shotcup petals at ranges less than 30 cm, irrespective of manufacturer, shotshell length, and birdshot size. When a variety of shotguns were tested, it was found that one weapon with a very short barrel and cylinder bore did not exhibit petal spread until a range of 30 cm was reached. The remaining shotguns, with longer barrels and full choke, all demonstrated definite petal spread at a range of 12.5 cm. The long, narrow configuration of .410 shotcup petals may explain their early spread and the production of petal abrasions at ranges of less than 30 cm.     

Revisiting renewable portfolio standard effectiveness: policy design and outcome specification matter

Renewable portfolio standards (RPS) differ widely across US states. Prior research findings on the effectiveness of these policies to stimulate renewable electricity deployment are equally wide ranging. This study investigates patterns of RPS policy design and analyzes the effects on policy outcomes measured at the level of utility compliance. Measuring organizational outcomes of RPS corrects for the first time the challenges of prior research focused on state-level renewable capacity or generation outcomes. The quantitative analysis also takes into account the complexity of RPS design, by making use of a state-by-state database of RPS design characteristics developed for this study. Patterns of RPS design across states are compared, including the compliance schedule, scope, eligibility of resources, quotas and subsidies, renewable energy credit provisions, as well as enforcement and penalties. Together, the map of state RPS design and the new approach to RPS outcome analysis illuminate the diversity of RPS policy practice across the United States. They suggest the need to both account for the variety of design characteristics and accurately specify the policy outcomes in evaluations of these policies.
