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

Abstract: In a continuing quest to build and defend world markets for tobacco products, tobacco companies have long been involved in international cooperation and information‐sharing through their own international corporate networks, as well as through national and international industry trade associations. This is evidenced in tobacco industry corporate documents now freely available on the internet. In order to institute effective tobacco control policy, policy‐makers needed to become equally astute at sharing information across national boundaries and at considering the cross‐national implications of policy and legislation. The World Health Organization has been instrumental in developing the Framework Convention on Tobacco Control (FCTC), and Canada has played an important part in this effort. The FCTC contains both demand‐reduction provisions and supply‐side provisions intended to reduce tobacco use worldwide. As a signatory to the FCTC, Canada has pledged to adhere to these provisions, thereby providing Canadian public administrators with effective tools to reduce tobacco use and its associated health burden both nationally and internationally. Sommaire: En cherchant continuellement à développer et à défendre les marchés mondiaux pour les produits du tabac, les sociétés productrices de tabac sont impliquées depuis longtemps dans la coopération internationale et le partage d'informations par le biais de leurs propres réseaux de sociétés internationales et d'associations professionnelles nationales et internationales. C'est ce qui ressort des documents des sociétés productrices de tabac auxquels on peut accéder librement sur Internet. Afin d'instituer une politique efficace de contrôle du tabagisme, les décideurs politiques ont dù devenir astucieux quant au partage d'informations et à l'étude des répercussions transnationales des politiques et des lois. L'Organisation mondiale de la santé a fortement contribuéà l'élaboration de la Convention‐cadre sur la lutte contre le tabagisme (CCLCT), et le Canada a joué un rôle important sur ce plan. La CCLCT contient à la fois des dispositions relatives à la réduction de la demande et d'autres relatives à l'offre qui visent à réduire la consommation de tabac dans le monde entier. En tant que pays signataire de la CCLCT, le Canada s'est engagéà respecter ces dispositions, fournissant ainsi aux administrateurs publics canadiens des outils efficaces pour réduire la consommation de tabac et le fardeau sur la santé qui lui est associéà l'échelle nationale et internationale.  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

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

Despite détente, the superpowers continued their Cold War practice of spying on one another throughout the 1970s. Yet intelligence is largely ‘missing’ from the historiography of détente. Why? Based on newly declassified data, ‘Détente in Deep Water’ reveals the geopolitical calculations behind the ‘Glomar response’ and how that legalese operated to limit disclosure of intelligence operations starting with AZORIAN/MATADOR, the CIA-led project to salvage a sunken Soviet submarine using the Hughes Glomar Explorer, a ship ostensibly owned (under a cover story) by industrialist Howard Hughes. Glomar’s diplomatic backstory sheds new light on the historical relationship between intelligence collection and foreign policy.  相似文献

Although all good social science research is by its very nature comparative, criminology and criminal justice have only recently embraced cross‐national research as a mainstream activity. This paper presents a brief history of the development of the subfield of empirical comparative criminology and criminal justice, assesses a typology of comparative studies, and identifies sources of comparative data. In addition, the paper discusses the benefits and drawbacks of using various available data sources which support macro‐, micro‐, or mixed‐ level analyses. Finally, the paper discusses the impediments to and the future of comparative crime and criminal justice research.  相似文献
