We have obtained high‐resolution elemental data on Lapita ceramics (3200–2700 cal year bp ) from Fiji, Tonga and New Ireland using chemistry‐based inductively coupled plasma–mass spectrometry (ICP–MS). These data show clear elemental distinctions between Lapita pottery manufactured in Fiji, Tonga and New Ireland, and demonstrate significant elemental variation in Fijian ceramics collected from settlements in close proximity to one another. Therefore, we anticipate that ICP–MS will become an effective technique for tracking the transfer of Lapita pottery within and between different island groups in Oceania. 相似文献

There are several hypotheses why urban scale affects wages. Most focus on agglomeration economies that increase labor demand, especially for high‐skilled workers (e.g., dynamic externalities stress knowledge transfers, and imply the urban wage gap favors skilled workers). Others stress urban amenities that increase labor supply and decrease wages. Amenities should have a stronger influence on affluent households if they are normal goods. By examining whether urban‐scale affects net returns to education, it can be determined whether skilled workers are influenced more by urban productivity or amenities. Empirical results suggest net returns to education decline with urban scale, implying a key role for urban amenities in affecting skilled workers. 相似文献

This article explores the conjuncture of Christianity and development in light of the establishment of a new Gogodala church in Western Province, Papua New Guinea. In the paper, I examine the ways in which members of this new church, the Congregation of Evangelical Fellowship (CEF), are utilising the concept of dance to comment on the failure of both expatriate missionaries and the dominant Evangelical Church of Papua New Guinea (ECPNG) to prepare the Gogodala community for development. I trace how mission-instigated abstention from dance became emblematic of a Christian lifestyle, and remains central to the constitution and articulation of ‘Christian country’ in this part of PNG. The incorporation of dance into CEF services and conferences, then, posits a challenge to the expatriate mission and ECPNG. In the process, dance has become a metaphor for a communal search for development as well as a reinterpretation of the Christian and pre-contact past. 相似文献

This research investigates the intersection of radiography and aDNA, two commonly used methods in bioarchaeology. The goal of this project was to investigate the effects of radiation on the ability to amplify DNA from bone. Bones (n = 124) from domestic pig (Sus scrofa) feet were randomly sorted into a control group and four treatment groups: (1) single exposure X-ray; (2) single exposure CT; (3) multiple exposures X-ray; and (4) multiple exposures CT. Number of PCR cycles required to amplify DNA in 100 bp, 200 bp and 400 bp segments were used as a proxy for the amount of available DNA. In the 200 bp CT sample, distal phalanges required significantly more amplification cycles than did the other bones and were removed from analysis. Results suggest that in general radiation exposure fragments DNA thereby decreasing the amount that is amplifiable. While these results are suggestive, further research is required to elucidate the degree to which radiation fragments DNA in archaeological specimens. 相似文献

This article is based on empirical research which was undertaken as part of the Sci:dentity project funded by the Wellcome Trust. Sci:dentity was a year-long participatory arts project which ran between March 2006 and March 2007. The project offered 18 young transgendered and transsexual people, aged between 14 and 22, an opportunity to come together to explore the science of sex and gender through art. This article focuses on four creative workshops which ran over two months, being the ‘creative engagement’ phase of the project. It offers an analysis of the transgendered space created which was constituted through the logics of recognition, creativity and pedagogy. Following this, the article explores the ways in which these transgendered and transsexual young people navigate gendered practices, and the gendered spaces these practices constitute, in their everyday lives shaped by gendered and sexual normativities. It goes on to consider the significance of trans virtual and physical cultural spaces for the development of trans young peoples' ontological security and their navigations and negotiations of a gendered social world. 相似文献

Spatial autocorrelation, resulting in pattern or structure in geographically distributed data, is discussed in theoretical and practical terms. Tests for spatial autocorrelation are presented, along with an explication of the relationship between autocorrelation models, the product-moment correlation coefficient and the spatial autocorrelation test statistic. Two archaeological examples illustrate the application of the auto-correlation test statistic. The first uses a hypothetical data set, which shows the type of map patterns that appear with various levels of spatial autocorrelation, and the second examines the terminal distribution of long-count-dated monuments at lowland Classic Maya sites. The results of the second example fail to support arguments for simple patterning in the cessation of the erection of these monuments and, by inference, in the Maya collapse itself. Finally, it is argued that while the identification of spatial autocorrelation is often the goal of spatial analyses, the presence of autocorrelation violates the assumptions of certain statistics used in such analyses. 相似文献
