Strontium isotope values (87Sr/86Sr) in bone and tooth enamel have been used increasingly to identify non-local individuals within prehistoric human populations worldwide. Archaeological research in the Midwestern United States has increasingly highlighted the role of population movement in affecting interregional cultural change. However, the comparatively low level of geologic variation in the Midwestern United States might suggest a corresponding low level of strontium variation, and calls into question the sensitivity of strontium isotopes to identify non-local individuals in this region. Using strontium isotopes of archaeological fauna, we explore the degree of variability in strontium ratios across this region. Our results demonstrate measurable variation in strontium ratios and indicate the potential of strontium analysis for addressing questions of origin and population movement in the Midwestern United States. 相似文献

Cooper, a Folsom arroyo-trap bison kill site in northwest Oklahoma is composed of three large-scale kill episodes. The bison bones have been examined for butchering evidence and exploring the butchering pattern. Damage categories to cortical bone are indentation, cut mark, helical fracture, and impact blow. The 99 elements damaged are from 36 carcasses across all three kills, and damage morphology indicates both lithic and bone expediency tools were used in the butchering. Animals are being butchered in an upright position on their stomachs, with transverse and abdominal muscles the focal point. Experimental butchering of a bison replicates the reconstructed sequence and underscores a gourmet butchering style for the Cooper kills. 相似文献

This article seeks to explore some problems in Jurgen Habermas's account of political norms and values in Western society. Using examples from Australian political discourse, it is argued that Habermas has neglected to analyse some of the ways in which political consensus can be generated in Western society. In particular, he has failed to acknowledge adequately the role played by liberal norms and values in attempts to reconcile conflicts between the individual and general interest While Habermas has made important contributions to social theory, such deficiencies limit his usefulness for Australian political scientists who wish to analyse some crucial aspects of Australian political culture. 相似文献

Concerns about the decline in uptake of secondary geography education continue despite arguments supporting the value of geography education, the power of geographical thinking, and geography’s critical role in preparing students to deal with complex challenges. Already constrained by neoliberal politics of disadvantage, young people must plan and prepare for chaotic futures. Consequently, young people are becoming distressed and worried about their futures and feeling powerless as society fails to adequately address these issues. In this article, we ask what schools and universities can do as place-based public institutions to serve young people to effectively respond to eco-anxiety and build capacities to surf the unrelenting waves of change. We draw on journeys that brought three young doctoral candidates to study geography. From their stories, we sketch what a geographical education could offer in terms of relevance, practicality, and engagement with transformative system change. We think that under current world conditions, this is a moment to revive geography education and give it renewed purpose to encourage young people to develop skills and competences to tackle wicked problems. 相似文献
