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

In 2006 a cast-iron coffin was discovered in an unmarked burial plot in Lexington, Missouri. A multifaceted investigation
was conducted to provide historical documentation and possible identification of the individual. The coffin is an early Fisk
Patent Metallic Burial Case. Osteological analyses indicate that the skeletal remains belong to a 20 to 30 year old white
female who consistently ate an omnivorous diet with significant amounts of C4 plants or seafood. Rib morphology and her burial
garments suggest she frequently wore restrictive clothing. No gross skeletal pathological lesions or trauma were observed
except for a patch of reactive bone and an atypical pattern of bone remodeling on the visceral surface of the sixth rib. Subsequent
bacterial DNA analysis of the ribs and sternum indicate the presence of tuberculosis infection. Although not conclusive, multiple
lines of evidence are consistent with the skeletal remains representing Elizabeth (Triplett) Stewart who died in 1854 of pulmonary
tuberculosis. This multidisciplinary research significantly contributes to the local history of Lexington, Missouri and provides
a likely identification of the deceased individual for the Stewart Family. 相似文献

Following earlier examples of mapping the subsurface of shell bearing sites using augering, we employ percussion coring to identify early Holocene shell midden components at two types of sites on the Northwest Coast of North America. We describe a method for mapping subsurface components at shell bearing sites including basal deposits, paleosols and transitions between distinct cultural components. Our research was undertaken for the purpose of identifying early Holocene shell middens above the modern shore, and as components below large shell midden villages. Our results augment the developmental trajectory of shell middens on the Northwest Coast by suggesting that pre-5000 BP forms of these sites may be more common than previously thought. In light of these results, we argue that the Northwest Coast cultural historical sequence, which locates an increase in the number and rate of accumulation of shell middens beginning 5000 years ago, to be premature. However, there are insufficient data from shell middens in the early Holocene, a sampling problem that the percussion coring methods described here can address. 相似文献

This paper examines the imaginative geography of Elizabeth Bowen’s 1929 novel The Last September. Drawing on Said’s analysis of imaginative geographies as registers of territorial identity, I consider the ways in which Bowen’s text maps Anglo-Irish territorial identity in early twentieth-century Ireland. Reading the text as an authoritative, albeit subjective, record of Anglo-Irish experience in Ireland, I identify four interconnected spaces which constitute the imaginative geography of the novel: the open, empty and isolated country; a wider landscape of resistance and control; a distant but necessary England; and an historical landscape of colonial decline. In conclusion, I outline how the concept of imaginative geographies provides a useful lens through which the often fragmented and conflicted nature of territorial identities, both during and after the colonial period, can be explored. 相似文献

This paper presents new 500 year interval palaeogeographic models for Britain, Ireland and the North West French coast from 11000 cal. BP to present. These models are used to calculate the varying rates of inundation for different geographical zones over the study period. This allows for consideration of the differential impact that Holocene sea-level rise had across space and time, and on past societies. In turn, consideration of the limitations of the models helps to foreground profitable areas for future research. 相似文献
