Normal fusion of the acromion process in humans begins at about age 15 and should complete ossification by age 22–25. Os acromiale occurs when fusion of the acromial epiphysis does not follow its normal ossification pattern, resulting in the retention of a separate epiphyseal end to the acromial process. Depending on how the metaphyseal junctures fuse, differential size and shape of the unattached acromial segment is produced. As a result of shoulder anatomy and the mobile epiphysis, os acromiale is associated with shoulder impingement and rotator cuff problems. The purpose of this study is to document the frequency of os acromiale in the Robert J. Terry Collection and gain a perspective on the occurrence of os acromiale in this specific US population. The overall frequency of os acromiale in the sample of 1594 skeletons was 8.34%. This study also evaluates the prevalence of os acromiale between sexes and ancestral groups in the Terry Collection. Significant frequency differences in the expression of os acromiale were found between both ancestry and sex; the black male sample has the highest frequency (12.47%), with a lower occurrence in the black female sample (9.22%). The white sample exhibited observably lower frequencies, with the white males at 6.8%, and white females at 3.2%. Size and shape and side expression (laterality) showed no significant differences between the sexes. However, significant differences in laterality by ancestry were observed; black males exhibited 48.3% bilateral expression, while white males exhibited bilateral expression only 29% of the time and 54.8% had a right lateral expression. Based on the results presented in this study, it is suggested that there is a genetic causation for os acromiale, which may or may not be exacerbated by physical activity. The use of this anomaly as an additional non‐metric feature in inferring familial relationships and personal identification is discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

考古出土的秦始皇兵俑是秦朝十分珍贵的实物资料,具有重大的历史、科学和艺术研究价值,其“千人千面”的特点更是备受关注,被认为是秦人的真实写照。现代人体测量中,头面部特征因其多受遗传因素作用,少受环境因素影响,被广泛应用于分析各民族之间的亲缘关系。通过采集50个样本的兵俑头部高精度三维点云数据并提取了头面部特征,运用样本相关性分析和数据大小排序的统计分析方法,与现代29个群体或地区头面部特征进行了对比研究。结果显示秦始皇兵俑样本的头面部特征完全各异且高度相关,同时与现代群体或地区的头面部特征差异性较小,定量化地明确了秦始皇兵俑的相关特点。 相似文献

Anatomical features related to water deficiency were analyzed in archaeological plant charcoal as a paleoenvironmental indicator. The end of the Aguada settlements in the Valley of Ambato (Catamarca, Argentina), which took place towards the end of the first millennium of this era, was used as the case study. Tools from Ecological Anatomy were applied to recreate paleoenvironmental scenery for the studied processes. The results of the analyses showed that this area must have been undergoing a period of arid conditions during the studied period. 相似文献

晚清国家观变化所呈现的强烈鲜明的爱国主义精神,恢廓的世界眼光以及各种国家观念纷然杂陈等时代特色,不仅是晚清国家观变化的重要内容和标志,更是当时“千古未有之变局”之纷繁复杂的社会现实在国家观念上的反映。上述特色非但使晚清国家观注入了新的内涵,也加速了晚清国家观由传统王朝观向近代国家观的转变;并对当时中国社会的历史发展及其走向产生了重大而深远的影响。 相似文献

论文以调查和访谈资料为依据,阐述了印尼棉兰华人社会发展与历史变迁的过程,并在此基础上总结出棉兰华人因受周边华人社会影响,兼及殖民种植经济传统与移居型城市特点而形成的独有社会特征:政治参与具有华人社会传统特性;坚守中华传统文化并吸收了西方文化、土著文化;闽南语或普通话日常使用较普遍;经济上居于印尼社会和华人群体的边缘,实力有限;与其他族群相处较为融洽;以横向分化为主的华人社会,各群体间互动频繁,边界较为模糊。 相似文献

In light of the ongoing urban shrinkage debate, planners stressed the need for new planning concepts and strategies. In this respect, the relevance of involving civil society in governance of urban shrinkage has been emphasized. So far, however these issues have received limited attention. This paper aims to contribute to the debate by investigating (1) how actors in civil society experience urban shrinkage and (2) their perspectives on the governance of urban shrinkage. We study this in two shrinking medium-sized cities: Heerlen (the Netherlands) and Blaenau Gwent (Wales). To answer these research questions, we make use of the concept of social capital. We follow a comparative case study design, primarily basing the analysis on data from 52 in-depth interviews. In the case studies, specific patterns of social capital can be observed: strong place attachment, strong informal participation and weak trust of civil society in local governments. However, the experience of urban shrinkage and the reaction to shrinkage differs. We conclude that understanding shrinkage and addressing it are predominately context related. Explanations based on historical developments and welfare state provisions are offered. The paper ends with reflections on the implications of these findings for governance of urban shrinkage. 相似文献
