The 1983 change in surplus vote transfer procedures for the Australian senate and its consequences for the single transferable vote

Among the 1983 changes to the electoral rules for Australian Senate elections using the Single Transferable Vote (STV) was a new procedure for determining the transfer of vote surpluses. The adoption of this modified (‘inclusive’) Gregory method has tended to be overlooked in the literature, yet as this article shows—using both hypothetical and real-world examples—it incorporates an anomaly that could have significance for electoral outcomes. This has important implications not only with regard to whether the ‘correct’ candidate is elected, but also for wider social choice debates over the quasi-chaotic nature of STV.     

Young People's Narratives of Rural-Urban Difference

Although recent research by geographers interested in children and young people has examined young people's experiences in a range of both 'rural' and 'urban' environments, the significance of narratives of rural-urban difference for young people's identities has received comparatively little attention. This paper draws on theories of narrative identity to explore how narratives of rural-urban difference (and, in particular, the cultural hierarchies created and reinforced by these narratives) are significant for the construction of young people's identities. Using empirical material drawn from two separate studies in the USA, one from a mid-sized Sunbelt city and one from rural northern Vermont, the paper examines ways in which narratives of rural-urban difference are significant for young people's senses of self, processes of 'othering', and the constitution of local youth cultures.     

Decolonising,Multiplicities and Mining in the Eastern Goldfields,Western Australia

In this ‘postcolonial’ era, peoples and places around the globe continue to face ongoing colonisation. Indigenous peoples in particular experience colonisation in numerous forms. Despite recent attempts to ‘decolonise’ indigenous spaces, hegemonic systems of production, governance and thinking often perpetuate colonial structures and relationships, resulting in further entrenched colonisation or ‘deep colonising’ (Rose, 1999). The interface between indigenous communities and the mining industry provides fertile ground for the tensions emerging between decolonising and deep colonising. Gold mining operations at Placer Dome's Granny Smith mine in the Eastern Goldfields of Western Australia present a valuable case study for examining this tension. Changes taking place at the mine site are decolonising in intent, though outcomes may be deep colonising in effect. Recent discussions among cultural geographers over meanings of place, Ollman's (1993) notion of vantage point and a broadly postcolonial literature inform consideration of this tension. Acknowledgment and incorporation of multiple vantage points into new resource management systems allows current hegemonic approaches to be rethought, and provides insights for the shift towards genuinely decolonising processes.     

Assessing the applicability of portable X-ray fluorescence spectrometry for obsidian provenance research in the Maya lowlands

Recent innovations in portable energy-dispersive X-ray fluorescence (PXRF) spectrometry have increased its utility for the geochemical characterization of obsidian artifacts for archaeological provenance research. However, concerns over the utility of PXRF instrumental analyses have been raised, focused on the validity and reliability of the geochemical data produced. Here we adopt the framework of Richard Hughes (On Reliability, Validity, and Scale in Obsidian Sourcing Research, 1998), whereby reliability addresses instrument stability and issues of measurement while validity pertains to an instrument’s ability to discern geochemical source provenance. This is done in order to test the utility of PXRF instruments for archaeological provenance research. k-Means cluster analysis was used to test the accuracy of PXRF through statistical comparison of data acquired via laboratory and portable energy-dispersive XRF instruments. Multivariate analysis was employed to demonstrate obsidian source representation at two Classic Maya archaeological sites in southern Belize – Uxbenká and Ek Xux – and to test the validity of data obtained from a PXRF instrument in answering archaeological research questions pertaining to regional interactions between lowland Maya polities. Results suggest that portable XRF instruments produce internally consistent results. However, data acquired from a PXRF instrument are not statistically equivalent to other XRF instruments. This is to say that while PXRF is not a reliable technique, it is valid for questions pertaining to geochemical source representation.     

Assessing the reliability of pRIA for identifying ancient proteins from archaeological contexts

The use of immunological techniques for identifying the origin of proteins and inferring foodstuffs exploited by prehistoric occupations has been conducted for several decades. Cases of experimental laboratory and archaeological studies have shown the potential of these techniques for reliable results. However, very few of these case studies employ archaeological sites that have excellent preservation and high-resolution spatial contexts between identifiable faunal remains, features, and stone tools. We present an assessment of the identification reliability of one immunological technique, protein radioimmunoassay (pRIA), using faunal remains and stone tools from two sites from arctic and subarctic contexts. The results of this research indicate that, even in contexts with excellent preservation, the identifications produced by the pRIA technique are subject to misidentification and cross-reactions due to diagenetic alteration of proteins. We propose a higher minimum reaction value (percent binding of labeled antibody) that mitigates these effects, and renders the pRIA results more reliable for ancient, poorly preserved organic remains.
