Effects of positional restraint on oxygen saturation and heart rate following exercise 总被引:1,自引:0,他引:1
D T Reay J D Howard C L Fligner R J Ward 《The American journal of forensic medicine and pathology》1988,9(1):16-18
This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used. 相似文献

In Garcia v. San Antonio Metropolitan Transit Authority (1985),Justice Harry Blackmun held that the Tenth Amendment does notprevent the Congress from subjecting state and local governmentsto the provisions of the Fair Labor Standards Act, concludingthat the "political safeguards offederalism" are generally adequateto protect state interests on the national scene. This articleexamines the intellectual foundations of the "political safeguardsof federalism" and finds them inadequate. It then surveys thepost-Garcia scholarship to ascertain whether an alternativetheory of the Tenth Amendment has emerged. Concluding that ithas not, the author suggests the need for afresh approach inview of the hints contained in Justice Sandra Day O'Connor'sopinion in Gregory v. Ashcroft (1991) that five justices maybe ready to reexamine the central thesis of Garcia. 相似文献

Japan's hundreds of thousands of small manufacturing enterprises not only provide high-quality inputs to large Japanese companies, but also are becoming innovators and growth generators in their own right. In addition to help from larger customers, small Japanese companies can call upon an array of public support mechanisms, including about 170 local Kohsetsushi examination and technology centers which provide research, testing, training, and guidance for firms with under 300 employees. With their intensive geographical coverage, broad range of technical services, and nominal fees, these centers offer small Japanese firms a readily available and effective source of assistance to improve their manufacturing operations, technology, and products. After reviewing the changing context for small manufacturers in Japan, the article examines the role of local Kohsetsushi centers in small firm modernization. This article considers the history, organization, and services of the Kohsetsushi system, explores the operation of five case study centers, and discusses how small Japanese firms benefit from Kohsetsushi services. Finally, there is an assessment of the strengths and weaknesses of the Kohsetsushi system. 相似文献

Numerous books assert that the Mafia long had a prohibition against engaging in narcotics trafficking, either for reasons of morality, or else because of the public stigma attached to drugs. In reality, there are many problems with the belief in voluntary abstention. The mythical nature of internal prohibition, and the far different reality, will be illustrated from the case of Philadelphia, supposedly the base for one of the most powerful and traditional-minded of all the American Mafia groups, the family headed from 1959 to 1980 by don Angelo Bruno. We will attempt to explain the roots of the prohibition myth, both for writers and for the wider public that appears so endlessly enthusiastic about sagas of organized crime. Finally, the paper examines the implications of this myth for policy makers in successive wars on crime. 相似文献

Many phenomena of interest to political scientists involve what may be termed impersonal influence; that is, influence that derives from individuals' perceptions of others' attitudes, beliefs, or experiences. Others in this case refers not to the close friends and acquaintances that concerned the authors of classics such asThe People's Choice andPersonal Influence, but rather to the anonymous others outside an individual's realm of personal contacts. Modern mass media facilitate the influence of anonymous others by devoting considerable time and attention to portraying trends in mass opinion. This study explores the rationale for theories of impersonal influence, synthesizing existing research findings falling under this general theoretical framework, and investigating its psychological underpinnings using experiments embedded in representative surveys. 相似文献
