Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications. 相似文献

Family Drug Treatment Courts are a specialized calendar or docket that operates within the juvenile dependency court. These courts provide the setting for a collaborative effort by the court and all the participants in the child protection system to come together in a non‐adversarial setting to determine the individual treatment needs of substance‐abusing parents whose children are under the jurisdiction of the dependency court. This article is intended to give judges and others a judicial perspective on FDTCs, and to offer some assistance for those who are operating or who are considering creating one. 相似文献

Recent headlines comparing the health risks of nanotechnology to those of asbestos have appeared in newspapers throughout the country and on the Internet. Governmental agencies and standard-setting organizations have begun considering and actually adopting requirements to protect against such purported risks. The plaintiffs’ bar and potential plaintiffs have surely taken note. There is every reason to believe that the era of mass tort and class actions related to nanotechnology—“nanotorts” for short—is rapidly approaching. This article examines what nanotort claims might look like, the role that regulations and industry practices may play in such lawsuits, potential defenses to those claims, and what nanotech companies can do now to guard against future nanotort liabilities. 相似文献

This article develops a framework for considering the future requirements for U.S. maritime power. It does so by proposing that these requirements must be considered within the context of an integrated National Fleet—the combined capabilities of the three “Sea Services”—the U.S. Navy, U.S. Marine Corps, and U.S. Coast Guard. It also would include their reserve components, as well as the Military Sealift Command (MSC) and the Maritime Administration's Ready Reserve Force (RRF)—the two organizations responsible for maintaining the nation's strategic sealift fleet. 相似文献
