Erosion in the 1960s resulted in exposure of human skeletal remains from a Norse Christian cemetery at Newark Bay, Orkney, Scotland. One set of remains showed osteological evidence of advanced lepromatous leprosy, but the absence of bones from the lower limbs precluded definitive diagnosis. The aim of the present study was to determine whether Mycobacterium leprae could be detected in bone extracts, as a means of confirming the diagnosis of leprosy. Bone samples were examined from the suspected leprosy case and from a second contemporary burial thought to be free of disease. DNA was amplified by polymerase chain reaction (PCR) using primers specific for a repetitive element (RLEP) characteristic of M. leprae. Additional PCR tests specific for Mycobacterium tuberculosis and for amelogenin (a human gene suitable for sex determination) were also applied to the samples. M. leprae DNA was detected only in the skull sample from the suspected leprosy case. The DNA sequence was identical to that found in present day isolates of M. leprae. Positive results were obtained only using a PCR reaction designed to amplify relatively short stretches of DNA (<175 bp), suggesting the microbial DNA had undergone extensive fragmentation. There was no evidence of M. tuberculosis DNA in bones from the leprosy suspect or control individual. The ability to recover ancient samples of DNA provides an opportunity to study long-term evolutionary changes that may affect the epidemiology of microbial pathogens. 相似文献

This paper serves as an introduction to this theme issue on the topic of post-socialist identity politics surrounding nation building, national identity and nationalism. It presents an overview of the key processes of post-socialist identity formation in Central and Eastern Europe (CEE) and the former Soviet Union (FSU) in order to contextualise this collection of papers. This introduction outlines the key processes of identity formation and the treatment of nationalism under conditions of state-socialism, and then identifies the main processes of identity formation which have emerged in discourses surrounding nations and nationalities in post-socialist CEE and the FSU. A short account of each of the papers in the theme issue is then presented to identify the common strands of their analyses of post-socialist nationalisms. 相似文献

The late John Burrow, one of the most stimulating promoters of the distinctively interdisciplinary enterprise that is Intellectual History, was a vital member of what has become known as the ‘Sussex School’. In exploring the resonances of his singular and richly idiosyncratic contribution, this article places his unique historical sensibility within a series of interpretative contexts, demonstrating the vitality of writings that will continue to inspire and inform scholarship in the field for decades to come. 相似文献

坟丘的区划盛土法是指在筑造坟丘时将其分成许多区域,由不同人力分别承担作业的筑造方式。为识别区划界限可设置异色粘土带、土囊列或排列石材作为标志物。坟丘的区划方向都是从坟丘中心呈放射状分布的,随着坟丘规模的扩大,区划数也在增多。中国春秋时期已使用区划盛土法这种技术,因而这种盛土方法应当是起源于中国。 相似文献

The “concealed communities” of our title are the people archaeologists have often labeled as “marginal.” Archaeologists writing
about both prehistoric and historic periods have commonly made a range of assumptions about margins and marginality, and their
discussions have often categorized marginality as ecological, economic, or socio-political. Whilst it has been common to privilege
one or other of these categories in order to explain how societies worked, they are rarely mutually exclusive. In addition,
since marginality is relative, virtually any group might be made marginal depending on people’s perspectives in the past or
present. Sometimes marginality can be imposed (economically or politically), and sometimes even actively chosen. Defining
the “margin” is a complex business, and the term needs sensitive, context-orientated use to make it useful for archaeologists. 相似文献

Accessible built environments are a critical component of Canada’s commitment to disabled children’s ‘right to enjoy full and decent lives’ [United Nations Convention on the Rights of the Child. 1989. Convention on the Rights of the Child. New York.] . Although valid, reliable research data about the accessibility of built environments are key to developing related policies, these data currently do not exist. To begin to redress this gap, we conducted a case study series followed by a survey to determine the accessibility of schools, homes and neighbourhoods directly from disabled children (The ScHaN Project). To present a concise summary of the findings that can inform equitable, evidence-based policies, we developed a scoring system for their homes, schools and neighbourhoods. Although our findings illustrate that eliciting and interpreting data from these children were complex undertakings, it is clear that none of these central environments met Canada’s obligation to enhance equity by enabling their access, inclusion and participation. 相似文献
