The detection of human remains that have been deliberately buried to escape detection is a problem for law enforcement. Sometimes the cadaver dog and handler teams are successful, while other times law enforcement and cadaver dog teams are frustrated in their search. Five field trials tested the ability of four cadaver dog and handler teams to detect buried human remains. Human and animal remains were buried in various forested areas during the summer months near Tuscaloosa, Alabama. The remains ranged in decomposition from fresh to skeletonized. Cadaver dogs detected with varying success: buried human remains at different stages of decomposition, buried human remains at different depths, and buried decomposed human and animal remains. The results from these trials showed that some cadaver dogs were able to locate skeletonized remains buried at a significant depth. Fresh and skeletonized remains were found equally by the cadaver dogs along with some caveats. Dog handlers affected the reliability of the cadaver dog results. Observations and videotape of the cadaver dogs during field trials showed that they were reliable in finding buried human remains. 相似文献

Between 1781 and 1789 the American states attempted to share the costs of national, public goods through a system of requisitions. This paper uses a simple public goods analysis to show why rational states would not share costs as intended by the Articles of Confederation. This normative argument illustrates a potential flaw in the constitutional design of the Articles and provides insight into the decline of the American Confederation. 相似文献

In South Carolina v. Baker the Supreme Court struck a powerfulblow at constitutional federalism. As a result of this landmarkcase, the question of whether issuing tax exempt bonds is asovereign right of the states or a privilege they are accordedby the national government has been settled. Relying in parton precedent from Garcia, the Court determined that immunityis not a right under the Tenth Amendment. In addition, SouthCarolina established a new doctrine of intergovernmental taximmunity which formally accords superior powers to the nationalgovernment. Taken together, these results have implicationsfor the future course of intergovernmental fiscal policy aswell as the basic character of the relationship between thenational and state and local governments. 相似文献
