A shipwreck from the early 3rd century BC was discovered in the Black Sea's suboxic depths off Ere?li, Turkey, during the 2011 E/V Nautilus expedition. Remote investigation revealed the trawl‐damaged remains of a merchant ship carrying multiple amphora types associated with Aegean and Pontic production areas. Also discovered were elements of the ship's hull that show evidence of both pegged mortise‐and‐tenon and laced construction. The wreck provides crucial archaeological evidence for both maritime connectivity and ship‐construction methods during a period of political and economic transition. 相似文献

Yelang (夜郎), a mysterious state located in the south‐western area of early China and dating from the Bronze Age to the Early Iron Age (1300 bc – ad 25), is a cultural interactive junction between the Yunnan–Guizhou Plateau and the Yangtze River Basin. The Zhongshui Basin in Weining County, Guizhou Province, was one of the important distribution areas of the Yelang civilization. This area, which includes sites at Jigongshan (鸡公山; 1300 – 800 bc ), Hongyingpan (红营盘; 700 – 400 bc ) and Yinzitan (银子坛; 400 bc – ad 25), has provided a very integrated chronology, spanning from the Bronze Age to the Early Iron Age in the eastern Yunnan – western Guizhou area. To investigate human migration and horse‐trading at these Yelang sites, we conducted a strontium isotopic analysis on the teeth enamel of humans and horses unearthed from these three sites. The results indicated the following: (1) people at the earlier sites (Jigongshan and Hongyingpan) were all indigenous, whereas in the Yinzitan cemetery, there was a more immigrant population, and all the people who were buried in an upper limb flexed supine position were non‐local; and (2) most of the horses found at the Jigongshan and Yinzitan sites show different provenances, probably related to the famous Dian (滇) and Zuo (筰) horses recorded in historical documents, providing more clues for further study on horse‐trading in South‐West China during the Bronze Age and the Early Iron Age. 相似文献

The number of computerised tomography (CT) investigations of mummies has increased since the first published study in 1979. However, this approach has never been validated. We present a critical analysis of the literature (1979 to 2005). Relevant articles were selected via a MedLine search and analysed according to CT technique, methodology, and author's speciality. Thirty‐one original articles matched our selection criteria. Of these studies, 42% were authored by radiologists, while 26% had no contribution from radiologists. Hypothesis‐driven papers comprised only 9.7% of the total. While 84% of the studies had a stated purpose for conducting the CT study, only 67% of studies defined their CT protocol clearly. CT was used to study mummification techniques in 74% of instances, and/or to detect disease in 58%. Conclusions based on CT analysis were derived in 84% of studies, but only 32% of these answered specific questions. Furthermore, only 36% of these conclusions were related to the stated purpose of the study. Using the criteria of the grading system we developed, we found that 61% of studies were supported only by weak evidence. We conclude that evidence‐based research with better design should be encouraged in future palaeoradiological studies. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The effect of skeletal exposure in a marine environment is an area of taphonomy that has been little investigated at the microscopic level. Understanding the peri‐mortem and subsequent post mortem history of deposition and/or redeposition is extremely important for event reconstruction and to identify deliberate or accidental redeposition. The material used for this study comes primarily from the Mary Rose shipwreck (a marine mass fatality dated AD 1545), and forensic material recovered from marine, lacustrine and terrestrial contexts is retrospectively referenced. Work presented here outlines a definitive type of marine exposure seen in temperate shallow off‐shore and intertidal marine contexts, and illustrates how it may be differentially identified from terrestrial deposition and exposure. Furthermore, the effects of rapid deposition on skeletal remains have been documented, and results indicate that marine organism fouling activity can be fully inhibited by rapid deposition of sediment. The responsible organism itself remains unidentified, but produces tunnels which are peripheral in their distribution and maintain fixed dimensions and morphology and are here associated with marine exposure. This type of microstructural change is unique and is not found in terrestrial or freshwater contexts. The study demonstrates a taphonomic microstructural change to bone and teeth which may be identified microscopically and interpreted as evidence of marine exposure. Secondarily, the history of depositional exposure between the two main Tudor layers has provided a new level of detail concerning exposure and site formation processes. The earliest Tudor layer formed rapidly over a period of months and contained no evidence of microstructural tunnelling, whereas microstructural tunnelling was seen exclusively in the second Tudor layer, formed over a period of decades, a period during which the ship's hull collapsed and a more open marine environment dominated.

This study examines possible morphological variation in the knee joint of Homo sapiens with increasing age in ostensively healthy and non‐pathological distal femora and proximal tibiae. Throughout the lifetime of each individual, the hard tissue of the knee undergoes considerable remodelling as a response to biomechanical stresses, changes in bone microarchitecture and reduction of bone mineral content as a concomitant of ageing. The knee is also subject to greater levels of degenerative joint disease than any other joint. If death occurs whilst such diseases are in the earliest stages, initial bone changes may not be visually obvious in museum specimens. If such specimens are used for comparative analyses, it is hypothesised that changes might render it problematic if all ages are conglomerated into discrete samples. This study therefore investigates the degree to which the distal femur and proximal tibia change shape during ageing and, if changes are present, whether they are expressed similarly in males and females. It also examines whether changes are of greater magnitude than those morphological differences which might exist between populations. In an example population of African‐Americans, results indicate that there is a statistically significant difference in shape between age groups and those differences become progressively greater between the youngest and oldest adults. Results also show that although morphological variation caused by ageing is apparent, those shape differences attributable to sexual dimorphism are more powerful. When two additional populations are analysed jointly with the African‐Americans (Caucasian Americans and the European Spitalfields sample), results indicate that inter‐population shape differences are considerably greater than differences caused by increasing age. Results imply that it is justifiable to combine specimens of all ages into discrete samples for comparative purposes. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

ABSTRACTThe article provides a historical account of the younger generation of British Idealists’ (1880–1930) approach to international relations and human rights. By focusing on pre-Great War and post-Great War periods, it reveals the shift that occurred in their approbation of T. H. Green's theory of rights. It shows that the Great War put an end to perceptions of the Empire as a plausible and sustainable international order for the younger generation of British Idealists, as it did for the significant majority of liberal British intellectuals. Their work, especially in the post-Great War period, reveals an attempt at translating Green's theory of rights into an internationalist human rights theory, which they saw as being indispensable to maintain a stable international order. As an alternative to contemporary attempts to locate Green's rights theory within the cosmopolitan–communitarian divide in human rights theories, this study draws attention to the younger generation of British Idealists’ long neglected internationalist approach to human rights as a middle way position. 相似文献

Abstract This article investigates Tom Wolfe's assessment of the age-old debate between nature and nurture, the Cartesian mind–body problem, and the tensions between science, politics, and morality that result from the human struggle to explain what the components of a human being are. I begin with Wolfe's own study of what evolution and neuroscience tell us about the “Human Beast.” Wolfe is not certain that evolution tells the whole story of how human beings came to be who and what they are in the twenty-first century. Evolution got us to the point of speech but Wolfe is persuaded that at that point, evolution ended and speech took over. Speech, according to Wolfe, made the development of reason and ingenuity and the creation of culture possible. And it is culture, the shared set of human behavior, knowledge, and beliefs, manners, and mores, and, above all for Wolfe, status, which then informs human motivation and actions. Wolfe is open to the idea that neuroscience might eventually be able to explain every detail of how and why the human brain functions as it does but he is skeptical that it will be able to explain away completely the idea that each of us is an individual, striving for honor and success within our status sphere. 相似文献

This article investigates the conceptual and organisational connections between late nineteenth-century civil-liberties activism and the emerging human-rights paradigm of the twentieth century. The comparison of the two largest and most influential civil-liberties organisations to emerge in Britain and France before the First World War (the British Personal Rights Association and the French Ligue des droits de l'homme) has three objectives: to place the two groups in a wider context of civil-liberty organisations of the pre-First World War era and to identify personal connections and inspirations. Secondly, by analysing functional definitions of ‘rights’ and who these rights should apply to, the article argues that although one group conceptualised their activism on the basis of ‘civil liberties’ and the other on ‘human rights’ there were significant similarities between the approaches of the two groups. Moreover, differences stemmed from internal politics within each group rather than the dissimilar conceptual framework. Finally the article seeks to understand why the Ligue des droits de l'homme was much more successful than the British Personal Rights Association both in its ability to mobilise supporters, and in inspiring sister organisations in other European countries. 相似文献
