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

Certain Biblical passages if interpreted literally can be understood as advocating the use of corporal punishment in disciplining children. The purpose of this research was to determine if persons affiliated with religious denominations which emphasized a literal belief in the Bible would demonstrate less appropriate attitudes with regard to discipline than their counterparts who were affiliated with religious denominations which do not subscribe to a literal interpretation of the Bible. The sample consisted of 881 persons who were members of denominations classified as literal or nonliteral believers. Statistically significant differences were noted on the Physical Punishment Scale of the Adult Adolescent Parenting Inventory with persons, regardless of gender or their level of education, who were members of churches subscribing to a literal belief in the Bible preferring the use of corporal punishment over alternate methods of discipline as compared to their nonliteral counterparts.  相似文献

A risk marker analysis of assaulted wives   总被引:1,自引:0,他引:1  
In the wife assault literature, a number of risk markers have been identified. Using the data of the female respondents to the National Family Violence Survey (n = 699), a multivariate analysis was performed to examine which risk factors best differentiated between women involved in nonviolent relationships, verbally aggressive relationships, relationships exhibiting minor physical aggression and severely violent relationships. High levels of marital conflict and lower socioeconomic status emerged as the primary predictors of an increased likelihood of wife assault. Research implications are discussed.  相似文献

This paper examines the process by which R&D results funded by the Office of Conservation and Renewable Energy (CE) of the US Department of Energy (DOE) have generated commercial applications. It looks at examples of technology-transfer procedures and activitees across three of CE's component offices that correspond to the major energy end-use sectors: transportation, buildings, and industry. On the surface, the conservation programs would appear to have little strategic consistency and, therefore, lack the clear leadership many seek in a technology-transfer program. However, as an alternative to strategic consistency, one may tailor the technology-transfer approach of each program to its unique circumstances. This paper presents case studies of such tailoring, in which the diversity of approaches mirrors the complexity of the energy end-use markets and the private-public interests that must be negotiated to successfully commercialize energy-saving innovations. The paper discusses the lessons learned about the conditions requiring adaptive design and the structures and practices that have been proven effective.  相似文献

Public officials may subjectively use a variety of elements, including economic characteristics and political considerations, in their selection of locations and allocation of resources for economic development. Policy capture is a method that determines the impartial weighting of a broad number of elements which influence these decision makers as they operationalize programs. Non-political criteria that may influence the selection of sites for local economic development provide the basis of the analysis conducted in this paper. Public officials at various levels of responsibility assessed the chances of creating jobs for disadvantaged residents (employment success) for a variety of hypothetical areas chosen as an enterprise zone. Their responses give insight into policy decisions. There is a comparison of both individual responses and groups of respondents to the hypothetical data as well as to actual zones that were recently selected. Concluding remarks will discuss these results and the application of this method for enterprise zones and other policy analyses.We wish to acknowledge the extensive helpful suggestions of the editor and two anonymous reviewers.  相似文献
