Spatial variation of refractive index in a pane of float glass.

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.     

“Know-nothings” revisited again

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.     

Opposition to European integration and fear of loss of national identity: Debunking a basic assumption regarding hostility to the integration project

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.     

Relational Leadership,Storytelling, and Narratives: Practices of Local Government Chief Executives

This article examines the storytelling and narrative practices of an elite group of public administrators in the United Kingdom: local government chief executives. The authors do so through the lens of relationality, exploring the collective dimensions of leadership. The focus on leadership and stories embraces the narrative turn in public administration scholarship. It responds to calls for research examining the distinctive settings of everyday leadership action. The contribution to theory is a qualitative understanding of the relational ways in which stories and narratives are used in the practices of public administration leaders. The article analyzes four ways in which such leadership is accomplished: inviting an emotional connection and commitment to public service, making sense of organizational realities, provoking reflections on practices and assumptions, and managing relations with politicians. The authors offer an appreciation of how relational leadership influence can be generated by expressive narratives and storytelling rather than stemming from bureaucratic authority.
