Activity area analysis of archaeological soils using multi-element characterizations can illuminate how subsistence operations are organized and how subsistence behavior has changed over time, and is increasingly common at archaeological sites. However, in many regions it is impossible to examine the elemental signatures in known anthropogenic soil samples in order to compare them with unknown archaeological samples. This ethnoarchaeological study examines the chemical composition of the soils at known fish processing areas in the contemporary community of Tununak on Nelson Island, western Alaska. Using a quadrupole inductively coupled plasma mass spectrometer (Q-ICP-MS), the concentrations of the following elements in the soil extract were recorded in parts per million (ppm): aluminum (Al), barium (Ba), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), phosphorus (P), strontium (Sr), titanium (Ti), and zinc (Zn). Fish processing area features are elevated in various elements, including sodium, magnesium, phosphorus, potassium, and manganese, and Ba/Sr, Ba/Ca, and Sr/Ca are also useful in distinguishing between fish processing areas and offsite areas.  相似文献

On Nelson Island in western Alaska, some Yup’ik inhabitants built and inhabited semisubterranean houses until the early 1960s. This affords a unique opportunity to examine known activity areas of ethnoarchaeological soils using multielement chemical characterization of soils. These data can then be compared to archaeological investigations, allowing a nuanced and sophisticated understanding of the activities performed in the past. Here, we present elemental concentration data from soil extracts, generated with a quadrupole inductively coupled plasma mass spectrometer, of the following elements in the soil extract recorded in parts per billion: sodium (Na), magnesium (Mg), aluminum (Al), phosphorus (P), potassium (K), calcium (Ca), titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), strontium (Sr), barium (Ba), lead (Pb), and uranium (U). When compared to an offsite area, the sod house samples were enriched in phosphorus and magnesium, and specific areas within the sod house exhibited different signatures related to different activities, including the incorporation of wood ash and waste into the soil.  相似文献

There are about one million orphans in Malawi. The global response has been a mix of alarm and inaction, with well-intended efforts often stymied by misunderstandings about childhoods, family dynamics, and poverty in Malawi. This paper uses children's geographies and interviews with 25 orphans in Malawi to bring forward the everyday lives and circumstances of orphans at the micro-scale, while addressing the impact of macro-scale processes such as the Millennium Development Goals and transnational charities. The results point to specific problems with contemporary understandings of orphanhood in southern Africa and underscore the need for reflection on the effectiveness of interventions targeted at orphans as a discrete group.  相似文献

Oceania, with the exception of New Zealand, has received little comparative attention in studies of electoral reform. This article uses evidence from Fiji, Tonga, Papua New Guinea and Nauru, as well as New Zealand and Australia, in order to: understand the process of electoral reform at national and regional levels; examine variation in the process and consider whether theories of electoral reform from elsewhere apply to Oceania. It finds that electoral reform is a highly complex process that is influenced by the self-interest of parties, democratic values and diffusion.

除了新西兰,不大有人从比较选举改革的角度关注大洋洲。本文使用斐济、汤加、巴布亚新几内亚、瑙鲁以及新西兰和澳大利亚的资料,目的是在国家和地区的层面上理解选举改革的过程;探讨过程中的变异,并思考其他地方的选举改革理论是否适用于大洋洲。  相似文献

This article explores relationships between imperialism and nationalism, illustrated by their interactions in the struggle over devolved Irish ‘Home Rule’ and partition between 1885 and 1925. Ireland's partition border was primarily an imperial creation shaped by the prolonged, complex and unequal interactions between Irish nationalism and British imperialism. But partition was by no means an inevitable outcome of a mutually constitutive and ambiguous relationship where British imperialism had long characterised Ireland as a frontier zone but one within the core of empire. The Irish case serves as a reminder of the role of imperial arbitration in modern state and nation-building, and also in sowing the seeds of contemporary conflicts. This argument draws on the recent ‘re-discovery of imperialism’ and is advanced as a corrective to reading history backwards through the lenses of contemporary national states. It challenges the tendency to draw overly sharp temporal and spatial distinctions between imperialism and nationalism as rival ideologies and practices.  相似文献

This paper considers themes of species maintenance and place engagement in Yanyuwa country, northern Australia. It traces the complexity of interpretations and relational contexts involved in places that are commonly – and we argue – misleadingly, referred to as increase and magic sites. Examining one specific place, at which people carry out maintenance rituals, we explore the complex bonds that unite Yanyuwa with the geography that is the Ancestral Hill Kangaroo. Not content with the classificatory habit of declaring actions either increase oriented or hunting magic, this research more fully explicates the relational substance of places that play a key role in ecological health. This is achieved by asking how might the profundity of a place of relational importance, such as a maintenance site, be better understood and written of in ways that convey an Indigenous ontology and epistemology?  相似文献
