The use of radiocarbon frequency distributions to reconstruct prehistoric human and animal populations must account for taphonomic loss and other factors that affect the archaeological and paleontological records. Surovell et al. (JAS, 36, 1715–1724) have recently proposed a correction for “taphonomic bias” that is based on the radiocarbon frequency of a global sample of volcanic deposits. Analysis of 717 radiocarbon dates sampled from the alluvium of the San Pedro and Santa Cruz rivers and their tributaries in southeastern Arizona shows that discovery and scientific biases also play an important role in the creation of radiocarbon frequency distributions, and that the rate of “taphonomic bias” in prehistory is not predicted by the radiocarbon frequency of volcanic deposits. The latter principle is further argued using a sample of 123 Pliocene to Clovis-age proboscideans from the San Pedro Valley. We propose an alternative model that is based on the nature of the stratigraphic record, with discovery bias, scientific bias, taphonomic loss, and the shape of the calibration curve all operating to influence the temporal frequency distribution of radiocarbon-dated prehistoric phenomena. 相似文献

Since the 1999 Immigration and Asylum Act, asylum seekers in the UK have been dispersed across the country to zones of accommodation on a no choice basis. This paper examines the political practices and governmental rationalities which accompany the allocation of asylum accommodation in Britain through the National Asylum Support Service (NASS). The paper draws on discussions of the UK border as a site of ‘domopolitics’, the governing of the state as a home, to suggest that domopolitics is productive of particular relations of calculation, regulation and discipline through which the lives of asylum seekers are conditioned. These entangled modes of governance, it is argued, find expression in a logic of accommodation which acts to discipline asylum seekers and to reinsert modes of arbitrary sovereign authority into a regime of governmental regulation. The rationalities of governance that accompany accommodation create an account of housing which is deliberately decoupled from feelings of security, as accommodation becomes a key space through which a relation to the border is lived for asylum seekers. Domopolitics is thus shown to be productive of a politics of discomfort for those at the limits of the nation. 相似文献

The thermoluminescence phenomenon has been used for pottery dating and radiation dosimetry for sixty years and for forty years
has been applied to the study of meteorites, being successful in quantifying metamorphic histories and providing new insights
into terrestrial age and orbits. Here we review some of the fundamental properties of thermoluminescence with particular focus
on the study of small extraterrestrial particles. We suggest that natural TL data can be used to identify the burial and release
history of cometary particles and that induced TL measurements can provide in-sights into the mineralogy of particles (even
when largely amorphous) and the metamorphic history of those particles. We illustrate the use of TL to study small particles
by describing recent studies on micrometeorites and 10–100 μm fragments taken from the matrix of a meteorite Semarkona which
is type 3.0 ordinary chondrite. 相似文献

Colonial intellectuals at the end of Empire: Manning Clark's Australia and Guy Butler's South Africa
Jonathan Hyslop 《African Historical Review》2013,45(1):25-39
AbstractColonial masters considered it their right to take human remains collected from colonies or plundered as a result of war. The skulls of Chief Mkwawa and the sub-chief Songea were looted in the same manner from Tanganyika (now Tanzania) to Germany. While Chief Mkwawa’s skull was returned in 1954, the demands for sub-chief Songea’s skull are ongoing, with the Tanzanian community contesting ownership of human remains in European museums. The absence of bones in graves, particularly those of chiefs, have a major impact on the colonised people as graves are associated with communities’ spirituality and wellbeing. This article shows that without a final resting place for the victims of colonialism, mourning is difficult, traumatic and endless. Individuals, communities and nations bestow social, cultural and political significance on human remains, even those curated in museums. The significance of each group is attached to the affective memorialisation of personal bereavement. What happens, then, when the memorialised graves were created at a time when mourning was impossible and the authority to bury or not to bury was in hands of the colonisers? How do the colonial plunder of human body parts and the demands for their return unfold in the contemporary history of Tanzania? These are some of the questions 相似文献

This paper presents findings from an ethnographic case study in Germany investigating the relationship between shopkeepers and customers of small grocery stores owned by immigrants. The focus is on social practices within the shops and how those engaged in these activities make sense of them. Shops become meaningful through shared practices that revolve around selling and buying. However, this process is complex and not without conflict. Moving through the themes of belonging, remembering and socialising, I will show how the everyday lifeworlds of customers and shopkeepers, including their aspirations, expectations and uncertainties, intersect and how the shop emerges as a meaningful space through negotiation. Rather than looking at cultural differences alone, it is concluded that there can be significant other ways to understand multicultural places by focusing on the multiple ways that consumers engage with so-called ‘ethnic’ enterprises. 相似文献

A recurring abolitionist theme was that the failure to destroy southern black slavery would eventuate in the enslavement of northern white laborers. During the 1830s this theme was the particular province of a few evangelical, markedly antimaterialist 'left' abolitionists like William Goodell. More inclined than their cohorts to regard the northern social order as oppressive for increasing numbers of workers, these abolitionists were also more likely to accuse capitalist 'aristocrats' of aspiring to go further and chattelize their workers in emulation of their southern slavocrat allies. Such white-chattelization warnings, which assigned a virtually coequal role in the slave power to malevolent employers and other northern 'aristocrats,' were supplanted in the late antebellum period by ones that instead targeted slavery's mulattoization and the southern slavocracy's proclivity for exploiting this ongoing erosion in racial boundaries. These white-chattelization warnings, which Goodell also notably promoted, acquired greater antislavery support than had the earlier anticapitalist ones. The late-antebellum warnings substantially reflected the ascendance of northern nationalism and the additional legitimacy that it conferred on capital-labor arrangements in the free states. 相似文献

Recent work on southern women and intellectual life in the nineteenth‐century South has focused on women novelists. Relatively little scholarly attention has been paid to literary periodicals as important vehicles through which women earned financial reward and often regional or national reputations as authors and editors. Perhaps most significantly, southern women viewed periodicals as opportunities to speak out boldly on politics and current events, much more so than in the novel. The wide availability after 1820 of magazines and newspapers, made possible by their low cost and portability, provided the perfect forum for women who wished to push against traditional gender boundaries. In examining southern women’s contributions to early nineteenth‐century periodical culture, one sees a vital part of the foundation being laid for later movements for women’s suffrage. 相似文献

The suitability of imagery from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA series of satellites for the synoptic classification of circulation trends in the European Arctic is assessed with reference to data from three climate stations. Simplified synoptic cyclonic classifications are derived from the satellite imagery and tested against climate data. Five classes of frontal system are derived from the tracking of systems over the UK‐Scandinavia‐Baltic region using 1460 satellite images over two years. An index based on the qualitative interpretation of satellite imagery was related to the reference data. The tracking of the systems in the imagery also facilitates a comparison of travel times across the region and the frequency of occurrence. Frontal systems that remain largely stationary over the Baltic were found to correlate best with precipitation at the reference sites. The paper thus investigates the use of AVHRR imagery for the categorisation of weather patterns towards deriving quantitative relationships between circulation classes and weather elements (such as temperature and precipitation) where, for example, climate data are sparse or where skills required for the interpretation of Height Potential Fields are lacking. 相似文献
