Intercontinental exchanges between communities living in different parts of Eurasia during the late prehistoric period have become increasingly popular as a topic of archaeological research. The Qijia culture, found in northwest China, is one of the key archaeological cultures that can shed light on trans‐Eurasian exchange because a variety of imports are found in this cultural context. These imports include new cereals and animals, which suggest that human diets may also have changed compared with previous periods. To understand human and animal diets of the Qijia culture, carbon and nitrogen isotope ratios from human and animal skeletal remains were analysed from the type site of the Qijia culture at Qijiaping. The results demonstrate that human diet at the site mainly consisted of millet and animals fed on millet. C3 cereals, such as wheat and barley, did not contribute significantly to human diet, and no isotopic differences were found between adult and subadult diets. Furthermore, three outlying human results raise the possibility of exogenous individuals, perhaps in relation to the parallel movement of animals, crops and goods. This study provides human and animal dietary information for evaluating the nature of exchange and diffusion in eastern Eurasia at this time. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This paper presents some of the basic principles of bone fracture physics and outlines characteristics used by forensic anthropologists to distinguish gunshot trauma from blunt trauma. The fracture pattern of a cranium from a historic cemetery in Memphis, Tennessee provides an example of how the mechanism of trauma could be misinterpreted. The pattern of the perimortem fractures is indicative of gunshot trauma with a bullet entering one side of the vault and impacting the opposite side. Identification of radiating fractures, concentric heaving fractures, and observation of the direction of bevel on the fractured surfaces are essential for interpretation of the mechanism that produced the injury.  相似文献

Colgi, Cajal and the Neuron Doctrine   总被引:1,自引:0,他引:1  
Camillo Golgi and Santiago Ramon y Cajal shared the Nobel Prize in 1906 for their work on the histology of the nerve cell, but both held diametrically opposed views about the Neuron Doctrine which emphasizes the structural, functional and developmental singularity of the nerve cell. Golgi's reticularist views remained entrenched and his work on the nervous system did not venture greatly into new territories after its original flowering, which had greater impact than is now commonly credited. Cajal, by contrast, by the time he was awarded the Nobel Prize, was already breaking new ground with a new staining technique in the field of peripheral nerve regeneration, seeing the reconstruction of a severed nerve by sprouting from the proximal stump as another manifestation of the Neuron Doctrine. Paradoxically, identical studies were going on simultaneously in Golgi's laboratory in the hands of Aldo Perroncito, but the findings did not seem to influence Golgi's thinking on the Neuron Doctrine.  相似文献

Many Australians would concur with the view of the novelist Tim Winton that we have an ‘almost supernatural fear and hatred’ of sharks. Especially in the wake of fatal attacks by great white sharks (on average once or twice per year), the extent of fascination and fear within the population at large is undeniable. This paper rejects the frequently encountered explanation that this is because we have an ‘instinctual’, ‘hard wired’ and ‘primal fear’ of wild animals that can kill people. Its focus instead is on the contemporary cultural interpretations of great whites and their behaviour which come to the fore when fatal attacks take place.  相似文献

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period.  相似文献

This article examines the role J.A. Smith played in introducing Croce’s conception of history into British philosophy. In particular, it examines his influence on R.G. Collingwood’s incorporation of the Italian idealist conception of history into his own philosophy. The contentions that Smith was a key popularizer of Italian idealist ideas into Britain and that he helped to shape Collingwood’s intellectual developed is not new. Yet these interrelated topics have not been explored in any great depth. Collingwood’s own reticence over his intellectual debt to Smith, a lack of interest in Smith and an unfamiliarity with his philosophy have all contributed to this neglect. This article seeks to redress this neglect through analysing how Smith nurtured Collingwood’s adoption of a Crocean conception of history. To achieve its aim, this article first analyses Smith’s own reception of Croce’s conception of history. From this, it presents a contextualist analysis of Collingwood’s development of a Crocean conception of history and the role Smith played in its adoption. Finally, this article examines why, despite Smith’s influence over his intellectual development, Collingwood failed to acknowledge the intellectual debt he owed to Smith.  相似文献
