Comparison of a suspected biter's dental arches with the patterned injury of a bite mark is especially difficult when the bite occurs in an anatomic location with a small radius of curvature or with complex or compound curves. The authors present two case reports in which human skin was used as a template for the reproduction of a bite. In one case the victim's skin was used; in the other, the skin of a anatomically similar person was used. The use of inked dental casts, photography, and transparent overlays significantly reduced the errors common to analysis of bite marks in these highly curved areas. 相似文献

Survival of the public service ethos in Britain has been called into question following introduction of the 'new public management' and marketizing reforms in much of the public sector. This article examines how these developments have occurred in the NHS, using survey data to analyse NHS board members' substantive ethical values. Unexpectedly the results suggest that NHS board members with a predominantly NHS background appear less ethically conservative, more flexible and less risk–averse than those recruited from non–NHS backgrounds; and that as yet the NHS management 'culture' is not very homogenous in respect of 'business ethics'. The NHS reforms also appear to accentuate the tensions between transparent public accountability in NHS management and incentives not to publicize certain types of information. Recent codification of NHS 'business ethics' can be understood as an attempt to buttress the public service ethos against the increased moral strains of a quasi–market. 相似文献

The impact of new technology on public-sector service delivery and citizens' attitudes about government has long been debated by political observers. This article assesses the consequences ofe-government for service delivery, democratic responsiveness, and public attitudes over the last three years. Research examines the content of e-government to investigate whether it is taking advantage of the interactive features of the World Wide Web to improve service delivery, democratic responsiveness, and public outreach. In addition, a national public opinion survey examines the ability of e-government to influence citizens' views about government and their confidence in the effectiveness of service delivery. Using both Web site content as well as public assessments, I argue that, in some respects, the e-government revolution has fallen short of its potential to transform service delivery and public trust in government. It does, however, have the possibility of enhancing democratic responsiveness and boosting beliefs that government is effective. 相似文献

The effects of polls on public opinion and voting behavior have begun to attract considerable attention. However, aside from experimental studies and research on exit polls, the impact of preelection polls has not received adequate analysis. This paper investigates whether exposure to polls released during the campaign influences voter choices and how the electoral context of referendum versus candidate elections makes a difference in terms of polling effects. These questions were addressed in a cross-election comparison of the 1980 presidential campaign and a 1986 state referendum on the right-to-life issue. Basically, I found significant effects during the referendum, but weak effects in the presidential general election. 相似文献

A biomechanical study of the human vertebral artery with implications for fatal arterial injury 总被引:8,自引:0,他引:8
We studied the biomechanical behaviour of ring and strip specimens from along the length of 18 vertebral arteries taken from 16 subjects aged 28-90 years, in order to consider some of the factors which may play a role in vertebral artery rupture. The method was chosen to allow a comparison between circumferential distension (ring samples) and longitudinal extension, (strip samples). The samples were extended between the jaws of a tensile testing apparatus until the specimen broke and a number of biomechanical parameters were derived. These were the percentage extension to break, the tensile strength, Young's modulus and the peak load. There were a number of important findings. The vertebral artery was shown to be susceptible to longitudinal stretching with a number of strip samples breaking when extended by as little as 16-20%. The tensile strength and load at peak of the strip specimens were correspondingly lower than for the ring samples. Marked intersubject variations were shown for all these parameters and prominent changes in behaviour occurred along the vertebral artery. This study indicates that the artery may be susceptible to head and neck movements which cause the vessel to stretch, and intersubject variations in behaviour may be one important explanation for the marked differences in outcome which appear to exist in subjects who suffer broadly similar head and neck insults. 相似文献
