In the summer of 1984, police in Pinellas County, Florida, confiscated six identically colored imported Asian skulls (in a shipping case) from a private citizen. In May 1988, in nearby Hillsborough County, police confiscated a very similar skull from another private citizen, who allegedly had found it in an abandoned house. Aside from slight color differences between the six found in Pinellas County and the one found in Hillsborough County, the skulls are virtually identical in their osteological characteristics and condition and in the vital statistics derived from each. Each skull is as clean and dry as those typically sold by commercial scientific supply outlets in the United States. Each is edentulous (primarily premortem), between approximately 20 and 60 years of age at death, and morphologically Asian. Five of the seven are morphologically male, one is morphologically female, and one is a mosaic with respect to gender-related features. Police, medical examiners, coroners, and forensic anthropologists should be aware of such "souvenir" specimens, in the event that they encounter similar skulls. Discriminant function analyses for race and sex yield considerably conflicting results, which underscores the need for using extreme caution when interpreting forensic science estimates based on such techniques. 相似文献

Over the past decade, there has been an explosion of litigation addressing an employer's right to unilaterally amend or terminate medical benefits provided to retirees. The sheer volume of these cases and the variety of facts and legal theories have combined to obscure the patterns and trends that actually are emerging from this litigation. This article will describe the context of the struggle over retiree benefits and discuss those leading decisions in which the federal courts of appeals have established their rules for deciding retiree benefits cases. 相似文献

When technology is transferred from one context to another, it is an established principle that innovation must take place. Even though a technology is well situated in one context, it must be adoptively redesigned for another. The sharper the difference in contexts, the greater the adaptation. This paper describes a program to transfer technology among a very diverse group of organizations: contractors to the US Department of Defense (DOD). Specifically, it describes how the technology of electronic communication, including electronic- data interchange (EDI), is being pursued by both the DOD and its supporters. 相似文献

The “tragedy of the commons” is the familiar problem that open access to a common property resource leads to overexploitation and to zero profits. A commons model is applied to an example of state sponsored private violence, the practice of privateering or licensed piracy. It is predicted that the presence of uncertainty about the value of the prey will reduce the amount of exploitation effort, and that industry profits may be positive due to both uncertainty and heterogeneous exploiters. Using data from England's wars with France and Spain between 1625 and 1630, the model suggests that the commons, represented by enemy merchant shipping, was not overexploited and that privateering profits were positive. The dynamic paths of privateering effort, ships seized, and individual firm profits were, however, consistent with the normal expectation that commons exploitation will peak and fall, as competition drives down returns through entry. “England was never richer than when at war with Spain.” Sir Edward Coke 相似文献
