The leprosy known today primarily from tropical areas was a relatively common disease in European Middle Ages. This article describes two skeletons bearing palaeopathological indications of leprosy from a cemetery at ?atec in North-West Bohemia (Czech Republic). The archaeological context clearly shows that these individuals were buried prior to the second decade of the 12th century, and most probably in the second half of 11th century. This rules out the possibility that these individuals might have contracted the disease in connection with the Crusades, in which a Bohemian contingent under Prince Vladislav II participated from 1141 to 1142. Molecular genetic methods were applied to detect specific DNA fragments of the causative agent of leprosy, Mycobacterium leprae. The nasal concha of one individual yielded DNA that could be directly sequenced after isolation and amplification. The vertebral body of the second individual, on the other hand, did not provide DNA of sufficient quality for direct sequencing and only weak amplification was detectable. The morphological and genetic analyses both indicate that leprosy existed prior to the Crusades in medieval Bohemia, albeit that its prevalence was probably not as great as in northern or western Europe. 相似文献

A small iron gun recovered from the wreck of the Caroline warship Swan has been identified as a drake, a lightweight tapered-chamber design dating from the 1620s. It is the only known cast-iron example of such a piece made by John Browne, gunfounder to Charles I, who was the leading figure in its development and manufacture in England. The gun was found together with an associated carriage, port-lid, and case shot appropriate to its calibre.

The questions addressed in this paper are: (i) does wage inequalityincrease with local population size, and if so, (ii) what arepossible factors behind this increase? In a cross-section analysisof Swedish local labour markets using unique full populationdata, the article shows that urban scale, i.e. size of localpopulation, has significant positive effects on wage inequality.Testing for potential explanations, labour market diversification,human capital, migration, age structure and employment are shownto be significantly associated with inequality. Given theseeffects, the article raises the question of how to understandand incorporate scale effects into models of long-term changein wage inequality. 相似文献

In the context of education in England, an argument is put forward that Geography, as it is conceptualised in the National Curriculum, does not connect to either primary school pupils or their teachers. Reasons for this are explored and a proposal is made for a new paradigm for primary geography: ethnogeography. This proposal parallels work on ethnomathematics, which provides a political agenda to the study of maths and itself draws from Paulo Freire's politicization and consciousness raising through adult literacy. This pattern is applied to learning in geographical education. Drawing on the findings of a recent research project, a case is argued for ethnogeography and the implications for primary Initial Teacher Education courses, learners and the curriculum in primary schools and are considered. 相似文献

As contemporary society is increasingly structured around highly diverse flows of people, goods, and information, mobile populations will contribute more and more to the economic, environmental and social performance of their destinations. However, planning is largely focused on residential populations and their contribution to the performance of places and hardly pays attention to the implications of people on the move for these places. In this study, we propose an alternative approach towards the assessment of the performance of places by comparing mobile and residential populations. An empirical analysis of the Netherlands National Travel Survey suggests that planning could profit by analysing mobile populations and exploring the desirability and feasibility of influencing their decisions. 相似文献

The analysis of phytoliths, pollen, charcoal and other macroremains was carried out in the neolithic shelter of “La Grande Rivoire”, Vercors massif (French Alps). The results show the predominance of tree species, in the form of phytoliths, clustered pollen, stomata, small branches charcoal, needles, bark, buds… The practice of leaf fodder is already known in the alpine and circum-alpine area from archaeological and historical sources. The analyses of the neolithic dung levels of “La Grande Rivoire” illustrate the use of leafy and flowering tree branches as fodder. The results also suggest that some species were used for special purpose in relation with the tending of livestock (litter, dietary supplement, veterinary practices). 相似文献

A concern for progress is central to the public agendas of modern societies. Political actors compete with one another mainly with regard to their respective claims to bring about a better future, particularly in the economic and technological spheres. The focus on progress has, however, deeper roots which date back to the aspirations of the Enlightenment. Around that time, the belief arose that systematic improvements are made possible by the structural features of modern society and culture, improvements that will gradually release humanity from much of the suffering characterising its historical past. This article argues the persistence of a culture of progress, rather than easing suffering, in fact enhances and mobilises it for the pursuit of superficial forms of gain. It is also claimed the attempt by Habermas' critical theory to develop a broader and more satisfactory conception of progress fails to address this problem. The article suggests an alternative and more fundamental critique of progressive ideas is required. It reflects upon these abstract theoretical questions in connection with the concrete example of the 'adolescent crisis' and the role ideas of progress play within it. 相似文献

From 1967 to 1975 a team of archaeologists excavated the site of Tepe Yahya in southeastern Iran under the direction of C. C. Lamberg-Karlovsky. Although there are two forthcoming “final reports” (Hiebert (in progress), and Magee (in press); see also Lamberg-Karlovsky & Potts, 2001), analysis of the materials continues as opportunities allow. Metal artefacts, most especially those made of copper and its alloys, are found at this site from the late Neolithic through the Iron Age. Archaeometallurgical analysis, radiocarbon chronologies, and archaeological interpretation allow one to state when and how a type of metal or a style of object was invented, its use as a trade item, and its function and value to an ancient community. In the hopes of establishing a framework for future archaeometallurgical studies, most of the metal artefacts from Tepe Yahya, Iran, stored in the Peabody Museum of Harvard University, were analysed for elemental composition to complement stylistic and metallographic data. 相似文献
