We report here the first results of a method to extract and sequence mature enamel proteins from modern human and Neanderthal tooth enamel. Using MALDI-TOF/TOF mass spectrometry and a combination of direct sequencing and peptide mass mapping we have sequenced a peptide from the tyrosine-rich amelogenin peptide (TRAP) of the X isoform of the amelogenin protein for modern and recent human samples. We also report our results from two Neanderthal enamel samples where we were also able to recover fragments of the TRAP protein, which had a similar sequence to the modern human samples.  相似文献

This article argues that the Office of Indian Affairs (OIA) field nursing program of the 1930s, which continued much of the same assimilation-style health care practices begun generations earlier by missionaries and field matrons, perpetuated the nineteenth-century link between religion and health care. Following in the footsteps of their female predecessors, field nurses targeted native women for health education, emphasizing personal hygiene and individual responsibility at the expense of socioeconomic causes of illness. Native women nonetheless appear to have maintained agency and power in negotiating health and health care. Peaking during the era of OIA Commissioner John Collier's Indian New Deal, the history of field nursing problematizes this period, particularly with regard to women's experiences. The article is significant for its exploration of field nursing as a contested site of cultural negotiation, revealing issues of power and difference in the lives of American women.  相似文献

The nation is a relatively abstract imagined community that is visualised through a variety of symbols as well as communicative and performative practices. In this paper, we explore how the national territory, one of the foundations of the nation‐state, is performed on national‐day celebrations and brings the nation into being. Drawing on ethnographic research on national days in Burkina Faso, Côte d'Ivoire and Ghana, we show how the state's internal administrative divisions and ethnic differences are at once made explicit but also subordinated to the nation. Moreover, we show how in such celebrations, potentially disruptive or competing affiliations such as ethnicity and regional loyalties are re‐imagined. Both the rotation of the central celebration and its replication all over the national territory carry the nation into the regions and integrate the regions into the nation‐state. The ‘co‐memoration’ turns participants and spectators from locals into national compatriots and thus not only performs nationality but also performs the relationship among nation, state and citizen, set within a particular territory.  相似文献

Who participates in the European Capital of Culture? This article analyses participation in Stavanger, European Capital of Culture (ECOC) in 2008, drawing on data from a survey conducted among a cross-section of the population of the city and its closest surrounds. It examines whether there is systematic variation in the number and type of events attended across key social background characteristics such as gender, age, education and income, as well as interest in culture. It finds systematic, but small differences between the genders, age groups and people of different educational attainment, and no differences between people with high and low income. Participation levels are high in all social strata. However, interest in culture is an important predictor of participation. Differences in social background and cultural interest matter more for participation in high-brow events. The authors conclude that the ECOC event was fairly inclusive of different population segments.  相似文献
