A biological object was recovered from the pelvic region of an adult woman coded to SK13 unearthed from Oluz Höyük in Amasya, Turkey. The skeleton was dated to the medieval period on the basis of the burial customs and the calibrated 14C dates. The find was identified as a bladder stone on morphological, radiographic and chemo‐analytical grounds with the help of X‐ray diffraction, polarised energy dispersive X‐ray fluorescence spectroscopy, confocal Raman spectroscopy, and microscopic techniques. The mineralogical composition of urinary stone was found to be as calcium phosphate (apatite). Bladder stone disease is endemic in poor agricultural regions where the typical diet is mostly based on grain carbohydrate consumption with scarce intake of animal protein.

在朝鲜战争起源的问题上,学术界一直存在着争论.一些西方学者认为,朝鲜战争是在苏联、中国和朝鲜周密的共谋下发动的,这种说法后来被称为"三国同谋论".但这种说法与最近公开的资料并不相符.本文以中国、苏联的新资料为依据对以往的"三国共谋论"进行了反驳,并得出结论:中国不仅没有参加策划朝鲜战争,而且在一定程度上对发动这场战争持不赞成的态度.  相似文献

1998年7月,中国社会科学院考古研究所等对淇县境内和鹤壁市直接管辖区域内的一批晚商遗址进行了调查,以期从考古材料出发,寻找殷都朝歌遗存的线索,为今后围绕朝歌这一期望的目标所进行的考古工作提供科学依据。调查发现有新石器时代、商周遗址,但没有找到商代朝歌遗址及其切实存在的证据。  相似文献

This paper presents a review of the antiquity of periodontal disease, discussing past aetiological concepts in comparison to current research on the causes of this condition. As periodontal disease is analysable on dry bone specimens, it is possible to document its natural history. To date, little work has been done on an actual system of measurement for periodontal disease in such specimens. A new system of measurement is proposed, which is confined to evaluating the periodontal status of post-mortem skulls. The system is a modification of the Ramfjord index for periodontal disease (PDI) and can be adapted for both individual specimen measurement and for population studies. Seven skulls, ca. AD 500–700, from the Varden Site at Long Point, Ontario, were examined using the proposed system. Mean attachment loss was computed for each of the seven specimens. The results revealed one specimen with early periodontitis, four with moderate periodontitis and two with advanced periodontitis. This system provides a concise method for classification of the severity of periodontal disease in dry bone specimens that will be useful in documenting the history of this disease.  相似文献

中国"三农"问题的由来和发展   总被引:16,自引:1,他引:15  
中国在改革开放过程中出现的特有的城乡关系和特有的城乡发展路径,产生了中国特有的"三农"问题的理论.这个理论的形成和运用,对于深入认识我国的基本国情、用以指导社会主义现代化建设的实践和对其他国家的问题进行研究,都是很有意义的.我国"三农"问题总的情况是农业问题已经基本上得到了解决,但农民问题和农村问题还很严重,主要根源还在于计划经济体制下所形成的一套农村、农业政策还没有得到根本转变.解决农民问题和农村问题,要继续深化农村体制改革,下决心改革户籍制度,改革现有的土地承包制度,改革现有的国民收入分配格局和乡镇现有的政权体制包括财政体制.  相似文献

Micromammalian bone assemblages from modern pellets of the strigiform Bubo virginianus magellanicus, from the upper Atuel River (southern Mendoza, Argentina), were taphonomically analysed. The results allow us to place B. v. magellanicus in the category of intermediate modification (Category 2). This sample has also been compared with results from other members of this genus, in order to classify B. v. magellanicus as a taphonomic agent. The participation of the Bubo species in archaeological accumulations has been documented, but in Argentina, the role of B. v. magellanicus has been reported up to the present. It is partly because of the sequence of one archaeological site in the south of Mendoza Province called Laguna El Sosneado‐3 (LS‐3). However, considering the absence of a current taphonomic model of this owl, this participation was mentioned as a hypothesis. In the current investigation, archaeological and modern samples have been compared. The results indicate that the skeletal element assemblages recovered from LS‐3 were accumulated by strigiform birds. Taphonomical evidence of light modifications on units I and IV indicates that Tyto alba (Category 1) was probably the main species involved in these units, whereas the taphonomical evidence on skeletal element assemblages recovered from units II and III suggests the action of a strigiform with a major category of modification such as B. v. magellanicus.

Voltammetry of microparticles using a paraffin‐impregnated graphite electrode (VMP/PIGE) was applied as a very local and non‐invasive analytical technique in order to investigate the presence of remains of metallic plating on two ferrous and one cuprous artefact from the medieval period. The analyses have been performed locally and selectively on regions presenting particular features, such as texture, cohesion and colour differences. The results confirm local differences in chemical composition, leading to conclusions about the presence of metallic plating on these artefacts.  相似文献

Many studies have documented the benefits of urban agriculture, including increased food access, job creation, educational opportunities, and green space. A focus on its social benefits has fed an association of urban agriculture with social justice, yet there is a distinction between alleviating symptoms of injustice (such as disparate access to food or environmental amenities) and disrupting structures that underlie them. Despite its positive impacts, urban agriculture systems may reinforce inequities that practitioners and supporters aim to address. This paper reports findings from a 2‐year study of urban agriculture in New York City, which found race‐ and class‐based disparities among practitioners citywide. Using the lens of critical race theory, it argues that a failure to examine urban agriculture's role in either supporting or dismantling unjust structures may perpetuate an inequitable system. The paper concludes with recommendations for urban agriculture supporters and scholars to help advance social justice at structural levels.  相似文献

Summary

Scholars of international relations generally invoke Hobbes as the quintessential theorist of international anarchy. David Armitage challenges this characterisation, arguing that Hobbes is regarded as a foundational figure in international relations theory in spite of as much as because of what he wrote on the subject. Thus, for Armitage, Hobbes is not the theorist of anarchy that he is made out to be. This article agrees with the general thrust of Armitage's critique while maintaining that it is still possible to imagine Hobbes as a theorist of anarchy. Hobbes is a theorist of anarchy, not in a political sense, but in a metaphysical sense. This conception of anarchy is a reflection of a comprehensive theological account of reality that is grounded in an omnipotent God. Any historical inquiry into the foundations of modern international thought must take account of theology, because theology defines the ultimate coordinates of reality in terms of which the concepts of international thought are intelligible.  相似文献

Scholars have been studying the concept of public engagement and its role in the policy process for some time. Scholars have argued that understanding the interests and motivations of the public and engaging them in the decision‐making process can lead to better policy designs and, ultimately, better policy outcomes. However, studies of public engagement often assume that people have a desire to get involved in the policy process. This paper tests this key assumption using the case of nuclear facility siting in the United States to ask: what factors influence an individual's stated willingness to want to engage in the policy process? Using data from a national web survey fielded in 2013, we ask the public if and to what extent they would likely engage in the siting process if given the opportunity. Findings indicate that the likelihood of engagement varies rather substantially across individuals. We find that an individual's cultural belief system and existing level of political activity account for some of this variation. These findings suggest that public engagement programs may vary across groups and communities. In other words, the prospects of engagement are likely to appeal to some members of the population and not others.  相似文献
