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

Zuckert  Michael P. 《Publius》1992,22(1):123-142
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 sorts—and thus does notrely entirely on calculating selfinterest—but these aresignificantly different from the virtues posited by earlierrepublican theorists or certain contemporary interpreters ofThe Federalist.  相似文献

In this article we examine how increasing the reimbursement of physicians and expanding Medicaid eligibility affect access to care for children in Cook County, Illinois, which overlies Chicago. Using Medicaid claims and other data at the zip-code level, we compare the places where Medicaid children live with the places where all the physicians who treat children and those who accept Medicaid patients have their practices. Our findings suggest that the recent changes in legislation are unlikely to benefit extremely poor children, who are more likely to live in depressed inner-city areas, where there are few physicians. "Near-poor" children whose homes are dispersed throughout the county, who are now eligible for Medicaid as a result of the recent changes, are likely to see improvements in their access to care. Further changes in policy, aimed at enhancing the capacity of institutions providing care, could improve access for the children of the inner city.  相似文献
