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.

Settler Colonial Strategic Culture: Australia,AUKUS, and the Anglosphere

Australia's history as a settler colony within the British Empire fundamentally shapes its sense of security within the Indo-Pacific region. Australia has consistently looked outside of its region for security and sought partners on the explicit basis of political, cultural, and ethnic similarity. What role does Australia's history play in shaping its foreign policy? We argue that these choices in foreign policy are inextricable from Australia's history as a settler colony on the farthest reaches of the British Empire. The AUKUS Agreement (AUKUS) is an example of how Australia operates to preserve racial hegemony in the face of non-white threat — real or perceived. This research utilises critical discourse analysis to interrogate elite-level discourse around AUKUS to ascertain the dominant narratives that inform its creation, the issues it seeks to address in Australian security policy, how it is structured by historical narratives of security, and how it functions to structure those narratives going forward. This article seeks to participate in the growing push to decolonise International Relations by illuminating the way Australia is ontologically and epistemologically invested in the preservation of racial hegemony.
