This study investigated the influence of an authority figure on eyewitness identification. Participants watched a staged crime
and then were administered a photo lineup by either an authority (policeman) or non-authority figure (civilian). Participants
in the authority condition were more likely to choose a lineup member than those in the non-authority condition. There was
no effect of authority, however, on the accuracy of the identification decisions. The lack of a deleterious effect suggests
that the presence of a police officer during identification procedures does not create an unduly suggestive situation or have
undesirable effects on eyewitness identification decisions. Although witnesses' choosing behaviors did not increase the rate
of identification errors, the effect of the administrator's authority on choosing was reduced when unbiased instructions (vs.
biased instructions) were presented to the witnesses. Thus, support was found for the use of neutral instructions during eyewitness
identification procedures. 相似文献

Conclusions The present study has attempted to artriculate a central issue of Mahäyäna soteriology through an examination of the writings of two Mädhyamika masters, Bhävaviveka and Candrakïrti. The purpose here has been to demonstrate a further criterion for the retrospective designation of their respective philosophies with the terms Svtantrika and Prasangika an exhaustive study of the nature of the Hinayäna wisdom according to the Mädhyamika school would entail an analysis of the writings of many other masters, especially those who produced what has been called the Yogäcära-Mädhyamika synthesis. To attempt to determine the position of Maitreyanätha, for example, on this issue would entail an analysis of the famous Five Treatises (the Dharmadharmatävibhaa, the Madhyäntavibhaga, the Mahayanasutrlamkara, the Uttratantra, and the Abhisamayälamkära) as well as the myriad commentaries on these works. It is possible to speculate briefly here on what the position of Nägärjuna may have been on this issue and then go on to discuss the implications and possible motivations of the views of Bhävaviveka and Candrakïrti. 相似文献

This paper compares the Medicare prospective payment system (PPS) to four all-payer rate-setting systems that operated under HCFA waiver authority. The study examines the experience of Medicare, Medicaid, and commercial insurers under the two approaches. Data from several American Hospital Association surveys and from Medicaid 2082 report forms are analyzed. The paper concludes that the all-payer waiver programs have been as successful as PPS in controlling the rate of growth in Medicare costs. In addition, Medicaid programs are more successful in controlling their outlays in all-payer rate-setting environments than when they "go alone." Finally, there is no evidence to suggest that hospitals can increase charges in response to greater financial need under either PPS or the state waivers. Nevertheless, it appears that commercial insurers are better able to compete with Blue Cross plans in all-payer rate-setting states than elsewhere. 相似文献

The Federalist claims to present a republican response to thetypical political problems faced by republics. That solutionrequired a departure from all models of republics known at thattime, and in particular a break with Anti-Federalist modelsthat posited heavy reliance on responsibility, understood aseither political accountability or as moral and political virtue.The Federalist challenges the Anti-Federalist notion that a"no-gap polity" is the means to safe and effective republicanism.It also challenges those who believe that virtue of people orrulers is the precondition of a republican polity. Publius doesrequire quasi-virlues of certain sortsand thus does notrely entirely on calculating selfinterestbut these aresignificantly different from the virtues posited by earlierrepublican theorists or certain contemporary interpreters ofThe Federalist. 相似文献

Rapidly escalating health-care inflation and congressionallymandated expansions have led to large increases in spendingfor Medicaid, the federal-state program of health care for thepoor. These increases came at a time when state budgets werealready under recession-induced stresses. In addition, 1991brought new pressures for Medicaid spending from the courtsand closer federal scrutiny and control over revenues used forthe program's state "match." Yet the Medicaid picture is farfrom bleak. Diversity, innovation, and an emerging stale policyrole also characterize the program in ways that epitomize thestrengths and weaknesses of the American intergovernmental system. 相似文献
