The skulls of two Japanese soldiers brought back to the United States following World War II suggest that more may be appearing in forensic science cases. Both cases are cranial vaults without faces or lower jaws. One was a fighter pilot. Both skulls have secondary characteristics of "dry house dust" adhering to the bone and have, to some degree, been painted. 相似文献

This article reviews the so-called competition strategy for medical care. It sets out the policy goals of the strategy and the problems in the present medical and insurance system that it seeks to address. It then describes several distinct formulations of the competition strategy, showing that it is not a single, rigid, monolithic approach, but rather a flexible combination of market-oriented approaches. Finally, it briefly discusses the technical and political problems and prospects of the strategy. 相似文献

This article describes the results of a 1981 survey of 1,000randomly selected scholars of American government and politicswho were asked to rank the most significant intergovernmentalevents and trends of the past twenty years. Responses were receivedfrom almost 40 percent of these scholars; no significant returnbiases were detected. These scholars ranked civil rights andvoting rights acts as the most significant events of these decades.General Revenue Sharing and the reapportionment cases were rankedsecond and third in importance. The increased flow of federaldollars to states and local governments was ranked the mostimportant trend affecting intergovernmental relations, followedby the increased public disaffection with government and thegrowing dependence of local governments on state and federalaid. The Vietnam War and the inflationary spiral it initiatedwas ranked as the most significant social event affecting thecourse of intergovernmental relations, followed closely by theenergy crisis and the beginnings of the "Great Society." Thearticle also examines the effects of party identification, age,year of degree, government experience, region, and city sizeon scholarly attitudes toward these events and trends. Whilethe overall rankings were not dramatically altered, partisanship,region, and city size all were factors found to be noticeablyrelated to scholarly rankings of these important events andtrends. 相似文献

A life-span developmental perspective suggests that variations in social context will lead to differences among individuals in their action orientations. An action orientation is defined by an individual's values, control beliefs, goal orientation, and decision-making perspective. To investigate differences in the action orientations of adolescents embedded in different contexts, 83 sophomore and senior high school students on either a vocational training or college-preparatory trajectory participated in the study. A discriminant function analysis of action orientations showed that the action orientations of vocational training and college-preparatory students differed: College-preparatory students had a career preparation action orientation and vocational students had an adult preparation action orientation; also, sophomores may have had a socializing orientation. The findings are discussed in terms of the developmental tasks facing students in different grades and on different life-course trajectories.

Deoxyribonucleic acid (DNA) was isolated from a number of spongy and compact human bone tissue specimens, and the yield was estimated on a "per milligram of starting tissue" basis. DNA was, in addition, isolated from a number of corresponding blood and bone tissue specimens. Spectrophotofluorometry and ethidium bromide visualization on minigels were used to estimate the quantity and degree of degradation of DNA. The DNA from several blood-bone pairs is shown to give concordant restriction fragment length polymorphism (RFLP) typing results by two different typing protocols with five different single-locus probes. DNA from several additional blood-bone pairs is shown to give concordant results for human leucocyte antigen (HLA)-DQ alpha phenotypes following polymerase chain reaction (PCR) amplification and hybridization to specific allele-specific oligonucleotide (ASO) probes, and for the variable numbers of tandem repeats (VNTR) length polymorphisms 3' to the human apolipoprotein B (APOB) gene following PCR amplification with specific primers and analysis of the products by electrophoresis and ethidium bromide visualization. 相似文献
