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.

Due to the diversity of contemporary archaeology, the aims and approaches of archaeological scientists and archaeological theorists are often at odds. I suggest that this position is problematic, both intellectually and methodologically, as both groups are fundamentally engaged in the same task: an understanding of past societies through the medium of material culture. This paper offers a review of the intellectual positions of both groups, with a brief discussion of the history of archaeological theory and an appraisal of its current trajectory. I will discuss how and why contemporary theoretical perspectives have fundamentally diverged from the perspectives of archaeological scientists and how the recent theoretical emphasis upon materiality offers a rapprochement between theoreticians and archaeological scientists. 相似文献

If negotiations produce an end to the Israeli–Palestinian conflict then a sovereign, independent Palestine may emerge. But what is required for it to succeed? Nothing is more important than the security of a Palestinian state–for itself, for Israel, and for the region: security trumps all else. In addition to the problem of dealing effectively with opposition to a peace agreement within Palestine or directed against it from outside, the nature and magnitude of the security challenge will depend in large part on three issues: the drawing of borders between Israel and Palestine–and whether they are porous or marked by a rigid line of barriers; whether Israeli settlements are withdrawn, or in part incorporated into Israel, perhaps through land swaps with Palestine; and what arrangements are made for Jerusalem. One answer is the creation of effective Palestinian military forces (in addition to police), but this course could be divisive; a second is the development of a series of Israeli–Palestinian confidence‐building and share–security measures, including intelligence cooperation; a third is progress towards reducing external threats to Israel–Palestine, including success in Iraq and in defusing other Middle East problems. Most useful, however, would be the creation of an American‐led peace enabling force, ideally modelled on NATO. This force would need to be agreed by both Israel and Palestine; it must be adequately staffed, trained and equipped; its duties and rules of engagement must make sense to all parties; and it must be part of a network of dispute‐resolution and confidence‐building measures in full partnership with Israeli and Palestinian authorities. 相似文献

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
