This paper presents some of the basic principles of bone fracture physics and outlines characteristics used by forensic anthropologists to distinguish gunshot trauma from blunt trauma. The fracture pattern of a cranium from a historic cemetery in Memphis, Tennessee provides an example of how the mechanism of trauma could be misinterpreted. The pattern of the perimortem fractures is indicative of gunshot trauma with a bullet entering one side of the vault and impacting the opposite side. Identification of radiating fractures, concentric heaving fractures, and observation of the direction of bevel on the fractured surfaces are essential for interpretation of the mechanism that produced the injury.  相似文献

Intercontinental exchanges between communities living in different parts of Eurasia during the late prehistoric period have become increasingly popular as a topic of archaeological research. The Qijia culture, found in northwest China, is one of the key archaeological cultures that can shed light on trans‐Eurasian exchange because a variety of imports are found in this cultural context. These imports include new cereals and animals, which suggest that human diets may also have changed compared with previous periods. To understand human and animal diets of the Qijia culture, carbon and nitrogen isotope ratios from human and animal skeletal remains were analysed from the type site of the Qijia culture at Qijiaping. The results demonstrate that human diet at the site mainly consisted of millet and animals fed on millet. C3 cereals, such as wheat and barley, did not contribute significantly to human diet, and no isotopic differences were found between adult and subadult diets. Furthermore, three outlying human results raise the possibility of exogenous individuals, perhaps in relation to the parallel movement of animals, crops and goods. This study provides human and animal dietary information for evaluating the nature of exchange and diffusion in eastern Eurasia at this time. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

As heritage research has engaged with a greater plurality of heritage practices, scale has emerged as an important concept in Heritage Studies, albeit relatively narrowly defined as hierarchical levels (household, local, national, etcetera). This paper argues for a definition of scale in heritage research that incorporates size (geographical scale), level (vertical scale) and relation (an understanding that scale is constituted through dynamic relationships in specific contexts). The paper utilises this definition of scale to analyse heritage designation first through consideration of changing World Heritage processes, and then through a case study of the world heritage designation of the Ningaloo Coast region in Western Australia. Three key findings are: both scale and heritage gain appeal because they are abstractions, and gain definition through the spatial politics of interrelationships within specific situations; the spatial politics of heritage designation comes into focus through attention to those configurations of size, level and relation that are invoked and enabled in heritage processes; and researchers choice to analyse or ignore particular scales and scalar politics are political decisions. Utilising scale as size, level and relation enables analyses that move beyond heritage to the spatial politics through which all heritage is constituted.  相似文献

This paper opens up a dialogue between mindfulness and the discipline of geography. As a meditative practice that cultivates ‘present-centred non-judgmental awareness’, we claim that the practices and insights of mindfulness have important implications for various forms of geographical enquiry. This paper argues that mindfulness can inform geographical practices in relation to epistemology and methodology, and contribute towards geographically informed critical psychological theory and action. More specifically, we claim that mindfulness could offer a practice-based context to support the study of affects, extend the application of psychoanalytical geographical methods beyond the therapeutic, and contribute to emerging geographical studies of behavioural power and empowerment. This analysis explores these sites of interaction through a series of reflections on the Mindfulness, Behaviour Change and Engagement in Public Policy programme that was developed and delivered by the authors. This more-than-therapeutic mindfulness programme has been delivered to approximately 47 civil servants working in the UK Government.  相似文献

Since the 1970s, there has been a fraught yet hopeful Aboriginal cultural resurgence in Australia. An element of this movement has been the establishment of Aboriginal art centres and cultural centres across Australia. Using a comparative approach to Aboriginal art centres, this paper analyses the appearance and characteristics of the more recent Aboriginal cultural centres. The methods used are a review of the literature on Aboriginal art centres, and for the less-researched Aboriginal cultural centres, a case study. This paper posits that cultural centre characteristics are shaped through the formation of alliances made possible by the advent of land rights, an Aboriginal cultural turn amongst Aboriginal and non-Aboriginal people, and changing approaches to regional development. While not themselves a movement that will lead to socio-economic change, these types of arts and heritage projects are aligned to such movements. With a larger scale and more central locations, Aboriginal cultural centres open up opportunities for larger and more diverse alliances, and therefore new opportunities for Aboriginal people’s participation, activism and expression.  相似文献

Narrative Policy Framework (NPF) is a new and maturing theory of the policy process that takes a systematic, scientific approach to understanding the social construction of policy realities. As such, NPF serves as a bridge between postpositivists, who assert that public policymaking is contextualized through narratives and social construction, and positivists, who contend that legitimacy is grounded in falsifiable claims. The central questions of NPF are: What is the empirical role of policy narratives in the policy process and do policy narratives influence policy outcomes? First, the contributions of NPF scholarship at three levels of analysis—micro, meso, and macro—are examined. Next, necessary conditions of a policy narrative are specified, accompanied by detailed discussion of the narrative components: narrative elements, narrative strategies, and policy beliefs. Finally, an empirical illustration of NPF—a case study of Cape Wind's proposal to install wind turbines off Nantucket—is presented. Although intercoalitional differences have long been studied in the NPF scholarship, this is the first study to examine intracoalitional cohesion or the extent to which a coalition tells the same story across narrative elements, narrative strategies, and policy beliefs. NPF is a new approach to the study of the policy process that offers empirical pathways to better speculating the role of narrative in the policy process.  相似文献
