In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献

Analyses of the same NORC poll relied on by Hyman and Sheatsley and a 1994 poll for theTimes Mirror Center for The People & The Press show that sizable portions of the U.S. public were know-nothings on both occasions. OLS regressions on both polls show that, although there are slight differences, essentially the same factors affect knowledge of international politics in 1946 and 1994. At bottom, Americans tend to be uninformed about foreign affairs because they are inattentive to events abroad. If it is true, as some students of U.S. foreign policy claim, that public opinion has an important and growing impact on national security policy, widespread public ignorance recalls Lippmann's concern about the democratic malady. 相似文献

Abstract. Opposition to the European integration project can stem from many different sources, but one that appears to be fairly fundamental is the threat that the European Union (EU) poses to long-established national identities. This contention may in fact appear to be so trivial as to make it uninteresting to the social science community. However, this article analyses the degree to which EU citizens do indeed feel their national identities to be under threat by the EU and the effect of such fear on general feelings about the integration process. The impact of fear of loss of national identity due to integration is then compared to the impact of other potential sources of variation in support for the integration project. The results indicate that while large proportions of EU citizens do indeed fear that the EU is threatening their national identity and culture, the effect of this fear on attitudes toward the EU is not all that substantial and other factors play an equal or greater role in explaining individual-level opposition to the EU. 相似文献

THESIS: Despite spending more on medical care than any other country in the world, the United States still boasts some of the worst patient outcomes of any developed nation. This disparity is especially true of how Americans give birth and die. These natural human transitions have become catastrophically expensive and leave patients and their families traumatized from unnecessary interventions. This article examines the costs and outcomes associated with the medicalization of birth and death and argues that alternatives exist that improve patient outcomes while lowering costs. Access to these alternatives will require changing current regulatory and reimbursement structures and providing trained support staff to help families navigate beginning- and end-of life decisions. 相似文献

Using the results of the 2005 Public Service Employee Survey (PSES), this paper identifies which factors have the greatest effect on employee satisfaction in the Canadian public service. Several hypotheses are tested against the backdrop of existing literature. In general, public servant satisfaction is affected by belief in opportunities for promotion, fair classification, adherence to client service standards, life balance, recognition by immediate supervisors, team relationships with colleagues, how well information is shared and, finally, belief in the abilities of senior management. Some interesting elaborations of these basic findings emerge when other variables are controlled. The discussion considers how the public service can be seen as a more desirable career choice. 相似文献
