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

Family Court of Australia has employed four Aboriginal Family Consultants within the Family Court Mediation Service in Darwin and Alice Springs. The consultants were selected from local indigenous people and assist indigenous families who are often in heated dispute over children following family breakdown and separation. The program ultimately seeks to promote access to justice for Aboriginal and Torres Stvait Islander people in the jurisdiction of family law. The program seeks to achieve this by assisting indigenous people to access and utilize the dispute resolution services provided by the Family Court. Family consultants work closely with court mediators in responding to the needs and issues of indigenous families in dispute. The article describes the model of intervention adopted and highlights the benefits of the program with reference to case studies. 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
