The aim of this paper is to examine the relationship between occlusal surface wear and approximal facet length in a North American archaeological sample of modern human hunter–gatherers (n = 111) and agriculturalists (n = 123). First maxillary molars (M1) were selected. The approximal wear facet was measured on the mesial surface of each M1 at the widest breadth using needle tipped digital callipers. Digital images were taken of the occlusal surface and wear was recorded as the percentage of dentine exposed to the total occlusal surface. Independent age estimate was based on age‐related changes, (pubic symphysis and auricular surface). Results show the hunter–gatherers had a significantly faster rate of wear on both tooth surfaces compared to the agriculturalists in each of the four age groups. Both lifeway groups showed a positive correlation between the two tooth surfaces during the early stages of tooth wear (less than 25% occlusal wear), where the percentage of occlusal wear and the length of the approximal facet increased at a similar rate. During the middle and final stages of tooth wear (occlusal wear greater than 35%) there was a strong negative correlation between the two surfaces in both groups. It is suggested this pattern is due to the shape and function of the M1. Both correlations were more extreme in the hunter–gatherers than the agriculturalists. When the per cent of occlusal wear exceeded 35% the length of the approximal facet started to decrease, and it is therefore recommended studies that include approximal wear exclude molars with heavy occlusal wear.

本文的“小美国人”是指中国新移民在美国生育的、具有美国国籍并于出生后不久就被送回亭江寄养的婴幼儿。本研究以位于闽江口的福州市著名侨乡亭江镇为调查点,追溯小美国人在当地跨国寄养这一现象的产生,考察小美国人在当地的寄养现状,分析小美国人的跨国寄养对当地社会经济和文化教育等方面的影响。文章认为,这些跨国寄养的小美国人兼具了作为传统意义的亭江人和作为法律意义的外国人的双重身份,是一个特殊的群体。他们在侨乡的跨国寄养,是国际移民网络的组成和延伸。作者建议当地政府和相关部门重视这一群体的特殊性,制定相关政策,帮助这批特殊的小美国人在当地健康成长。从长远看,这将有利于这些小美国人回归美国长大成人后,成为促进中美友谊的民间桥梁。  相似文献

中、美旅游网站对比分析及"虚拟距离衰减"预测模式   总被引:12,自引:0,他引:12  
李彦丽  路紫 《人文地理》2006,21(6):115-118
在解决旅游网站使用者满意度及其由此引发的旅游在线服务质量问题时,单维分析效果有限,本研究将评估推进到多维的新阶段。本文对中美旅游网站的类型、市场规模和经营模式进行对比分析,认为两地旅游网站的差异在于区域内部意识性、经营策略和发展阶段等方面。同时,发现两地旅游网站共同遵守“虚拟距离衰减”规律,并依此解释了旅游网站赢利与发展乏力的问题,提出了预测旅游网站发展模式的新方法—“虚拟距离衡量法”,这将为加强区域旅游在线管理提供参考。  相似文献

1901年义和团战争以后,美国社会围绕传教士参与对华劫掠兴起了一场争论,对这场争论的考察揭示出无论是马克.吐温和一些反帝国主义者,还是美国海外传教团体,争论双方都利用了当时流行的文明话语来论证自己的观点。这一文明话语为美国的扩张和海外非正式帝国的建立提供了支持和合法性,因而构成了一种帝国文化。  相似文献

Drawing upon postcolonial theorizing on diasporic positionalities and Homi Bhabha's theorization on ‘third space’ and hybridity, this study shows how young American Muslim women engage in their own interpretations of Islam based on their individual needs and situations. Individual in-depth interviews were conducted with 26 respondents in Ohio and Texas in order to gain insights into the identities of American Muslim women with immigrant backgrounds. Respondents emphasized their own ‘research’ on Islam as an important foundation of their faith. The narratives of the American Muslim women showed that they subverted and transgressed dominant meanings, while negotiating new ones through their everyday lived experiences. However, without indulging in an uncritical celebration of interstitial spaces, this study also strives to highlight the power relations implicit in the performances of complex, hybrid identities in the post-9/11 American context.  相似文献

The 1970s, the decade in which Susan Hanson took up an academic appointment in American geography, was a period of marked growth in women's representation and political activism in the discipline and of the emergence of feminist research and teaching. Susan's career illustrates the changes in consciousness, resiliency in the face of setbacks, and creativity of the times. Inspired by the women's movement, and exemplifying collegiality, women geographers identified masculine biases in scholarship and professional practices, initiated research and teaching on women and gender, and worked to enter the leadership of the Association of American geographers. Their efforts were the genesis of the feminism in the profession that has since flourished in the United States. It is fitting that Susan Hanson's leadership and contributions in this arena are widely recognized and honored.  相似文献

目前学界对于美国汉学史的研究,多侧重于美国汉学概况、研究范式转变和著名中国学家及其著述的研究,而缺少从华裔汉学者对美国汉学之影响这一角度研究的论著。论文就赴美华裔汉学者对美国汉学的影响这一论题作了总体性探析。结果表明,20世纪40年代,一批从事中国文史研究的华裔学者赴美潜心于中国文史研究。他们在美所从事的文史研究是美国汉学发展的重要组成部分,对美国汉学产生了重要影响。他们对美国汉学的基础性贡献和推进作用具体表现在:协力培育美国汉学的基础、矫正美国汉学发展中的流弊、开拓美国汉学研究的新领域。  相似文献

The examination of thin sections is a successful method for discovering provenance groupings of archaeological ceramics if non-clay inclusions in pottery paste can be identified with petrographically distinctive geologic sources. When this is not the case, geochemical analysis must be employed to search for more subtle evidence of such groupings. This situation is likely to arise in studies, such as the present one, where the objective is to discern local or subregional patterns of pottery manufacture and exchange. Ninety potsherds from site LA46326 in New Mexico were subjected to both INAA and petrographic analysis. The results of this conjoint approach are assessed in relation to geochemical theory and are analysed graphically and statistically.  相似文献

The Hohokam, the prehistoric farmers of the southern Arizona desert, have been the subject of increased archaeological investigation in the last two decades. This research is altering traditional views of the Hohokam. New data provide a stronger basis for discussing Hohokam origins and culture history. Although best known as irrigation farmers, the Hohokam had a complex subsistence base that relied on hunting, gathering, and a variety of farming techniques. Studies of site structure and settlement patterning reveal a degree of social complexity greater than previously recognized. The Hohokam were tied to surrounding groups through evolving exchange and interaction networks.  相似文献
