The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use. 相似文献

Optically stimulated luminescence (OSL) dating of heated/fired materials of archaeological importance from various parts of India was attempted. A single-aliquot regenerative-dose (SAR) procedure was used for palaeodose determination in the quartz grains extracted from the heated materials using the luminescence produced by blue light stimulation. In most pottery samples, the palaeodose obtained using SAR-OSL is ∼6% lower than the palaeodose measured using thermoluminescence (TL) method. Broadly, there is good agreement between the SAR-OSL and TL ages of the artefacts and their archaeologically expected ages. The results suggest that routine dating of heated/fired materials using the SAR-OSL procedure is more practicable, especially when the TL sensitivity of the quartz grains is poor and availability of datable material is limited. 相似文献

The South African War that broke out in October 1899 was bothvery old and very new. It was a traditional war, the last ofthe old-fashioned British imperial wars, with cavalry playinga significant part. But it was also a very modern war, for instancein the British Army's use of railways to subdue the Boers inthe early months of 1900, or the use of trench warfare by theBoers along the Modder river. It was disturbingly new in theway that it changed in the autumn of 1900 from a war betweenarmies to a guerrilla war against a civilian population, mostdistastefully so in the British concentration camps set up tohouse Boer women and children. Above all, it was a distinctlycontemporary war in its impact on the media, especially thenewspapers, and in the interaction between the media and thoseparticipating in the fighting. It was a significant war, farbigger than originally expected, and was therefore big news.The British Army, ill-prepared for the original Boer invasionof Natal, at first numbered 75,000 troops. In the end, the Britishand imperial forces totalled 450,000 with contingents from Canada,Australia, New Zealand, and India. The British lost 22,000 men,13,000 of them from disease. The Boers lost about 7,000 in thefield, while another 27,000 (many of them very young children)are estimated to have died in the concentration camps. Therewere also about 20,000 black and coloured Africanswho died in concentration camps, though this was little reportedat the time. So it was a major episode in British military history.The impact on British opinion of the relief of Ladysmith andespecially of Mafeking in 1900 was quite overwhelming. In afrenzy of jingo celebration, the verb maffickingentered the language. In these circumstances, the consequencesof the Boer War on the media and its representation of war wereinevitably massive. 相似文献

This mischievously artful essay plays out on several levels; think of them as storeys of an imaginary castle much like the real, solid, central Italian one it explores and expounds. On its own ground floor, the essay recounts a gruesome murder, a noble husband's midnight revenge upon his wife and upon her bastard lover, his own half–brother, in her castle chamber, in bed. In sex. Of course. The murder itself is pure Renaissance, quintessential Boccaccio or Bandello, but the aftermath, in fort and village, is more singular, more ethnographically delightful, as castle and village trace a ceremonious passage from frozen limbo to fluid grief and storytelling, finally set in motion by the arrival of the dead wife's brother. Meanwhile, one flight up, the essay retells my own investigation of the real castle's geometry, as I clambered through rooms, peered out windows, prowled the roof, and scanned blueprints seeking the places of the plotters' plots. In an expository attic, I lodge reflections on my teaching stratagems, as I led a first–year seminar into detection's crafts and exposition's ploys. All the while, on its rooftop, this essay dances among fantastical chimneys and turrets of high theory and literary practice, musing on the patent irony of artful artifice, which evokes both the irony and the pathos of scholars' cool histories about hot deeds and feelings. Art suggests we authors had best hide ourselves, unlike normal essayists, so as not to spoil the show. But, I posit, our self–effacement is so conspicuous that it proclaims our presence, as in fact it should, and, by so doing, trumpets the necessary tensions of our artifice and craft. Thus artfulness itself nicely both proclaims and celebrates the bittersweet frustrations of historians' and readers' quest for knowledge and, especially, for experience of a lost past. 相似文献
