A total of 60 pieces of rhino materials have been identified from the Nanjing Man site. Morphologically, they belong to the species Dicerorhinus mercki. Among the materials, 40 pieces are broken bones, and 20 are isolated teeth or jaw bones (totally comprising 41 tooth units). Among the teeth, 74% are deciduous, most of them attached to jaws. Other isolated teeth are not greatly worn, meaning they were not naturally replaced, so they represent juvenile animals. Because the skeletons are completely isolated and most of them are broken, their death can not be attributed to a natural trap. Therefore, it is very probable that hominid activities were associated with rhinos at this site. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Korea witnessed a steady increase in women marrying younger men from 8.5 per cent in 1993 to 14.3 per cent in 2009. This study examines those women marrying younger men in Korea through an empirical analysis using a large and reliable data set of more than 5 million observations collected from marriage register reports from 1993 to 2009. The results indicated that an increase in Older-Women/Younger-Men Marriages (OWYMMs) in Korea was mainly due to a steady increase in the woman’s age at marriage and show that women with a higher level of education and/or income than men were more likely to choose the OWYMM. That is, the incidence of OWYMMs was related more to the gap in the level of education or income between spouses than to the absolute level of education or income of individual spouses. In this sense, the results provide empirical support for exchange theory. 相似文献

Over the past four decades several workers have argued that the orientations of striations on the labial surfaces of the front teeth of Middle and Late Pleistocene fossils attributed to Neanderthals and antecedent archaic hominids can tell us something about handedness. These researchers have suggested that such scratches result from stone tools scraping across the incisors during ‘stuff‐and‐cut’ behaviours, and that they reflect directions of hand movements and handedness. In this study, we examine comparable wear features on the incisors of anatomically modern humans to determine whether striation angle may reflect handedness. The teeth from 66 individuals representing four groups with known differences in subsistence practices (Aleut, Arikara, Illinois Bluff, and Puye) were examined. Photomicrographs were made of the maxillary central incisor labial surfaces of all individuals at 56× magnification. These photomicrographs were scanned to image files, and orientations of all visible wear striations were measured using a semi‐automated image analysis procedure. Approximately three‐quarters of all labial surfaces showed a preferred striation orientation. Of those, most had preferred apico‐cervical or vertical striation orientations, independent of cultural affiliation. Few showed the tendency toward diagonally‐oriented scratches expected if handedness is related to scratch orientation. We found no evidence for ‘stuff‐and‐cut’ striations, despite the fact that at least one of the groups studied—the Aleut—are documented to have used this behaviour. In sum, there is evidently no relationship between striation orientation and handedness in the groups studied. It is, therefore, unlikely that labial scratch orientation in Middle and Late Pleistocene hominids reflects handedness if they used their front teeth in a manner comparable to that of any of the anatomically modern groups considered here.

CLARE MADGE 《Tijdschrift voor economische en sociale geografie = Journal of economic and social geography = Revue de géographie économique et humaine = Zeitschrift für ?konomische und soziale Geographie = Revista de geografía económica y social》1997,88(3):237-250
This article investigates the geography of fear surrounding the use of public parks in Leicester city, Britain. Fear was a major deterrent limiting the use of parks, especially for women, the elderly and Asian and African-Caribbean people. Certain fears were particularly important for specific groups: women were particularly fearful of sexual attack, the elderly of mugging and Asian and African-Caribbean people of racial attack. Women and African-Caribbean people were most liable to alter their behaviour as a result of their fears. The spatial outcomes of fear thus both reflect and reinforce social injustice based on gender and race inequality. As parks are becoming important foci of new environmental strategies for cities it is essential that local government is aware of the spatial consequences of the socially differentiated geography of fear, if all members of the community are to be encouraged to increase their participation in public parks. 相似文献

美国著名文学批评家爱德华·W·萨义德在《东方学》一书中提出了在西方实际上一直存在着与“先进的西方”相对的“落后的东方”,也就是所谓的“东方学”式的“二元对立”思维方式。它在西方国家以东方国家为对象大力推进殖民政策的过程中,已成为一种霸权话语。日本是一个东方国家,但是它在比西方国家落后几十年的状态下学习西方,并发展到以中国大陆为主要对象推进殖民政策。从日本近代文学家当时关于中国的言论当中也可以看出有类似于萨义德提出的“东方学”的思维方式。因篇幅的关系,本文试图通过借鉴萨义德在《东方学》里所提出的观点,重点围绕芥川龙之介这位作家,深入探讨他对中国的一些言论。 相似文献

This paper is the outcome of a lecture held at the Institute of Archaeology, University College London. It provides a summary in English of the archaeozoological research work which has been carried out in Central Europe during the last 30 years, with special reference to material from medieval times. It is shown that a thorough zoological analysis of bones from excavations provides much information for historical interpretation. Not only was the ratio of wild and domestic animals or of the different species of interest, but also the age and sex structure of the population by taking the function of the site into consideration. Some observations on animal teeth gave indications of distinctive handicrafts. Cut marks on cervical vertebrae of horse skeletons found as grave goods from early medieval times were considered in connection with beliefs and juridical conceptions of that time. 相似文献

现代物流与区域商贸中心的发展——以临沂市为例 总被引:2,自引:0,他引:2
现代物流是区域经济的重要构成要素,可以降低区域经济运行成本,改变经济增长方式,调整优化区域经济结构,形成新的经济增长点,促进以城市为中心的区域市场的形成与发展,特别是对具有一定商流规模的区域商贸中心的改造与发展具有重要的推动作用。临沂批发市场闻名全国,是典型的区域商贸中心,但滞后的现代物流制约了其进一步发展。应当积极规划发展现代物流产业体系,整合商流与物流,促进临沂商贸中心的持续健康发展。 相似文献

现代艺术是目前唯一在国际上占统治地位的艺术现象。本文从地理学角度出发研究现代艺术的发展演变。首先回顾了现代艺术的发展过程,重点分析了现代艺术的地域性特征,指出国际现代艺术体系有\"中心-边缘\"性的分布格局,从流派数量和艺术主题的变化方面总结了其发展演变特点,并且总结了历史上三次重要的艺术扩散过程。其次分析了我国现代艺术发展的时空分布和地理格局,指出我国现代艺术的中心位于东部沿海大城市,具有分布不均、在国际体系中地位不高的特征。最后指出我国城市积极参与国际现代艺术体系、提升文化艺术地位的重要性和途径。 相似文献

近代学人为后学开设国学书目者甚众,但以大学生为对象拟定国学读书书目的并不多,其中较有名者有吴汝纶、梁启超、胡适等人。他们三人为大学生所拟国学书目虽各异其趣,却有诸多相通之处:一是所拟书目均以传承国学为宗旨;二是所拟国学均有学习程度上的层级划分,以适应不同层次大学生的学习需求;三是所拟书目基本上是按传统图书四部分类法分类筛选,这种书目筛选法在相当程度上保证了所拟国学书目能系统、完整地传承国学。他们关于国学范围的界定、国学书目的筛选、国学书目的分级与分类等问题的思考对于当今中国大学的国学教育仍然有一定借鉴意义。 相似文献
