Bone density studies in zooarchaeology

Accurate bone density data are essential for assessing the influence of destructive processes in archaeological faunal assemblages. Unfortunately, the diversity of methods employed by different researchers to derive density values has resulted in recent confusion. Two recent publications in this journal [J Archaeol Sci 29 (2002) 883; J Archaeol Sci 29 (2002) 979] exemplify this state of misunderstanding. Both studies argued that the role of bone density in shaping archaeological faunal assemblages has been largely overrated, but both based their conclusions on density values that were inaccurately derived. The former employed a method of calculating bone density that has been largely discredited over the past decade [J Archaeol Sci 29 (2002) 883]. Within a larger discussion of zooarchaeological methodology, the latter provided an assessment of the current state of bone density research that inappropriately characterized the discrepancies between available sets of density data as a reflection of the differences between two technologies—photon densitometry and computed tomography [J Archaeol Sci 29 (2002) 979]. The actual dichotomy exists—irrespective of the technology employed—between studies that account for variation in the shape of bone cross-sections and those that do not. The different sets of density data currently available to zooarchaeologists vary tremendously in their accuracy. We review and evaluate the different techniques employed in the research of bone density patterns of mammalian fauna. Computed tomography produces the most accurate density data. For elements without medullary cavities, photon densitometry may provide density values of similar accuracy but only if a method of cross-sectional shape-adjustment is applied.     

The Wavy Line and the Dotted Wavy Line Pottery in the Prehistory of the Central Nile and the Sahara-Sahel Belt

The two type-sites of the Khartoum Mesolithic and Khartoum Neolithic (Khartoum Hospital and Shaheinab), in Central Sudan, were excavated at the end of the 1950s. The ceramics recovered from these sites, characterized by wavy line and dotted wavy line decoration, formed a cornerstone for identifying Mesolithic–Neolithic components along the Central Nile and across the Sahara-Sahel Belt. Moreover, they formed a model for an evolutionary sequence, and suggested a level of cultural uniformity for the Nilo-Sahara-Sahel Belt from the eighth to the fourth millennia BC. This paper examines these and other related issues.L'hôpital de Khartoum et Shaheinab, qui se situe au centre du Soudan, sont les deux sites archéologiques principaux de la civilisation mésolithique et néolithique. Ces deux sites furent découverts et excavés au cours des années 1950s. Les céramiques découvertes dans ces deux sites se caractérisent par leurs lignes continues et ondoyantes, et d'autres ondoyantes mais discontinues. Ces céramiques représentent la pierre angulaire pour les caractéristiques de la période mésolithiqueet néolithique dans le centre de la vallée du Nile et á travers la zone du Sahara-Sahel. De plus, elles ont constitué un modèle pour l'évolution et ont suggéré une certaine uniformité culturelle entre la vallée du Nile, le Sahara et le Sahel de huitième au quatrième millénaires avant J.-C. Cette recherche traite donc de ces points et d'autres aspects s'y rapportant.     

How Should We Wage the War on Drugs? Determinants of Public Preferences for Drug Control Alternatives

When citizens are presented with alternative policy solutions to a given social problem, why do they choose to support one over another? In this article, the authors analyze a survey of residents of the five largest U.S. metropolitan areas to understand determinants of public support for spending on three major components of American drug control policy: law enforcement programs, rehabilitative services for addicts, and school‐based prevention programs. The authors estimate effects of self‐interest, political socialization, and policy attitudes on support for total drug control expenditures and on preferences for each drug control alternative versus the others. Effects of group self‐interest, societal interest, and political socialization change dramatically across dimensions of support. Policy attitudes are strong predictors of both types of support, whereas individual self‐interest measures are not associated with either dimension.     

Palaeolithic radiocarbon chronology: quantifying our confidence beyond two half-lives

It is now three decades since Waterbolk introduced evaluation criteria to ¹⁴C chronology. Despite this, and other subsequent attempts to introduce quality control in the use of ¹⁴C data, no systematic procedure has been adopted by the archaeological community. As a result, our databases may be significantly weakened by questionable dates and/or questionable associations between dated samples and the archaeological phenomena they are intended to represent. As the use of chronometric data in general becomes more ambitious, we must pause and assess how reliable these data are. Here, we forward a set of evaluation criteria which take into account archaeological (e.g. associational, stratigraphic) and chronometric (e.g. pre-treatment and measurement) criteria. We intend to use such criteria to evaluate a large ¹⁴C dataset we have assembled to investigate Late Glacial settlement in Europe, the Near East and North Africa, supported by the Leverhulme Trust. We suggest that the procedure presented here may at least form the basis of the development of more rigorous, scientific use of ¹⁴C dates.     

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.
