This study is an osteobiography of a noble couple who were members of the “ruling elite” in the 18th-century Joseon period, Korea. The archaeological context and historical records indicate that the couple lived and died during a period marked by strict observance of social hierarchy. The husband's skeleton exhibits clear evidence of craniosynostosis and spinal scoliosis. In particular, congenital craniosynostosis of the skull likely caused deformities in his craniofacial morphology during his lifetime. The physical deformities and discomforts revealed by his craniofacial and vertebral skeleton shed light on the documented passivity and frequent disruptions to his government positions. Meanwhile, his wife's age at death, 93 years, is exceptionally long. The osteological investigation suggests that she seems to have lived without severe stressors. Her skeletal remains show no evidence of occupational stress or chronic disease. Until now, our understanding of the Joseon period nobility has predominantly relied on artifacts and summaries of the deceased's life discovered in tombs, as well as written documents such as diaries, evaluation records, and letters. This study reconstructs the lives of this couple through osteological evidence, historical records, and social context. This holistic approach will provide a novel perspective for a more comprehensive understanding of the lives of nobility and intellectuals of the period. 相似文献

It is only when one moves home or office that one really thinks about what gets left behind, what is discarded, and what we decide to keep. How we deal with this in our personal lives is interesting enough, where senses of loss and discard are potentially heightened given the intimate heritage which many familiar objects and items possess. But what happens when the transition is corporate, when an organisation moves? Here, briefly, is an archaeological perspective on the move English Heritage made in 2006, from its long-time HQ in Savile Row (London, UK) to new accommodation in Holborn and elsewhere. 相似文献

The need for experiments to study physical aspects of craft of the past is stated, as well as the necessity for them to have clear aims and to follow the established principles of scientific enquiry. These principles are discussed in this joint paper by ten maritime archaeologists and others, together with methods and some points of management critical to their application in this field. 相似文献

The resemblances between Melanesian Big Men and capitalist entrepreneurs have long fascinated anthropologists. However, even though traditional leaders in Melanesian societies resemble entrepreneurs in certain respects they are motivated by different concerns. In this paper, I consider the career of Noya of the Eastern Highlands of Papua New Guinea to demonstrate the contrasts and confluences between the roles of big man and that of entrepreneur. Noya is neither a traditional big-man nor a pure capitalist, but has drawn selectively upon the logic of each in his drive to achieve promience. His life story provides insights into how big-men articulate with the capitalist world system. 相似文献

Abstract. Employing recent anthropological perspectives on ethnicity and nationalism which have not yet been applied to any extent in research on cultural differentiation in Namibia, the article investigates problems and challenges in the process of nation-building in the recently independent state. Ethnicity and nationalism are here seen as socially constructed and ideologically practised phenomena, and the relationship between these ideologies is studied as one of ideological conflict. More particularly, the article investigates the formation, relevance and uses of ethnic identities; the relationship between ethnicity, class and the politics of ethnic nationalism; as well as some techniques, rhetorics and symbols employed in the social construction of nationalism in Namibia. In conclusion, the article argues the importance of making the nation-building project relevant to people not only through the creation of ever more effective and inclusive national symbols, but also through real economic and political reforms. 相似文献

Spatial clusters contain biases and artifacts, whether they are defined via statistical algorithms or via expert judgment. Graph-based partitioning of spatial data and associated heuristics gained popularity due to their scalability but can define suboptimal regions due to algorithmic biases such as chaining. Despite the broad literature on deterministic regionalization methods, approaches that quantify regionalization probability are sparse. In this article, we propose a local method to quantify regionalization probabilities for regions defined via graph-based cuts and expert-defined regions. We conceptualize spatial regions as consisting of two types of spatial elements: core and swing. We define three distinct types of regionalization biases that occur in graph-based methods and showcase the use of the proposed method to capture these types of biases. Additionally, we propose an efficient solution to the probabilistic graph-based regionalization problem via performing optimal tree cuts along random spanning trees within an evidence accumulation framework. We perform statistical tests on synthetic data to assess resulting probability maps for varying distinctness of underlying regions and regionalization parameters. Lastly, we showcase the application of our method to define probabilistic ecoregions using climatic and remotely sensed vegetation indicators and apply our method to assign probabilities to the expert-defined Bailey's ecoregions. 相似文献
