There is limited available data on the environmental context of the arrival of the first anatomically modern humans (AMH) in North Africa, and subsequent Paleolithic and Neolithic occupations within this region. Microvertebrates such as rodents, shrews, amphibians, and squamates are known to be good indicators of climate and landscape changes. They also represent continental paleoecological records that can be directly related to human occupations. Moreover, faunas and humans have been subjected to several dispersal waves through similar routes, and some rodents may present anthropophilous behavior. Therefore, by understanding the dispersal pattern and pathways of these microvertebrates, it is possible to propose scenarios for human dispersal events. In this study we took the rich microfaunal assemblages from the Témara region, Atlantic Morocco (El Harhoura 2 and El Mnasra Caves), and placed them within a broader synthesis, in order to highlight the role of microvertebrates in providing a better understanding of the human-environment relationship during the Late Quaternary in North Africa.  相似文献

The Rabat-Témara region of the Moroccan Atlantic coast reveals a succession of Quaternary palaeobeaches. This coastal area is dotted with numerous prehistoric caves. The study of the Upper Pleistocene coastal landscape associated with these caves is of paramount importance in the knowledge of human population subsistence. During the Upper Pleistocene, the ocean level changes drastically influenced the coastal geomorphology as well as the fauna assemblages. The chrono-lithostratographical analysis of the coastal sedimentary formations allows the distinction of three sequences rich in marine fauna. These sequences date from MIS 11 to MIS 5. The identification of malacofauna species from these deposits revealed 39 species, along with Bryozoans, Crustaceans, and Echinoids. These assemblages show a constant fauna cortege highlighted by the dominance of the amphi-Atlantic species Stramonita haemastoma. This species shows an increase in the number of specimens in the uppermost part of marine deposits, probably in relation with a climate warming in the MIS 5. This fauna of both intertidal rocky substrates and sandy substratum indicates environmental conditions close to the present-day Rabat-Témara coastline. As in other coastal locations of Africa from MIS 5, the Middle Stone Age Homo sapiens population benefitted from a littoral environment rich in coastal resources. Comparison between thanatocenoses and archaeological records allows us to identify both species available for Middle Stone Age population and those preferred for human use.  相似文献

宋末江西文人刘辰翁以耿直名,他具有江西文人的个性特点。同为江西籍文人,他继宋代欧阳修、杨万里以及其他江西诗派文人而来,并具有江西地域文化性格。同时因处于改朝换代和蒙古族入主的特殊历史时期,其个性更被扩张,他抒发对旧朝的哀怨和新朝的不平之怒,情绪激烈。这造成了其文学创作和文学鉴赏的不一致,其诗词创作有情真与自然的特色,而其文学鉴赏和主张则务求艰涩尖新。然而其实这些都是统一于其耿直的人格特点下,他继承江西大儒欧阳守道之学,表面上畔于圣人之道,实际则是一个有真性情和个性,坚持自我的儒士。  相似文献

Metok in Nyingchi Prefecture was the only county that did not have a road in the past. On October 31st, 2013, the Road to Metok was officially opened to the public. The opening of this road signified that now all counties in China can be accessed by road.  相似文献

The Changsha Street Corps originated in the local militia during the period of the Taiping Rebellion, and it played an important part in Changsha’s urban social management at the grassroots level. However, the role and influence of the street corps underwent changes during the process of modernization and the building of the modern nation–state. By 1920, although the street corps of Changsha still worked as the agent of the state at the grassroots level, its autonomy had been curtailed, and its social influence weakened. In the new social environment, even the maintenance of neighborhood interests became a challenge for the street corps. This article illustrates the readjustments in geopolitical and industrial relations during the process of urban modernization. It also illustrates how a new form of state power, namely the police, infiltrated the social management system, affected the traditional social structure, and complicated the interaction between modern state and society.  相似文献

采用光学显微观察、激光拉曼、紫外-可见吸收光谱以及高效液相色谱对河北隆化鸽子洞蓝棉袄蓝色、浅蓝色纤维以及百衲枕顶蓝色纤维进行分析研究.通过多种分析手段相互佐证表明,该组样品采用蓝草中的靛蓝染色,色素成分有靛蓝素和靛玉红.各样品中色素成分比例均不相同,推测至少在元代,人类已经能够有意识地调整制靛工艺,染出自己需要的色光.同时靛蓝染料耐光性耐热性差,对酸、碱和氧化均敏感,耐盐性及耐细菌性较弱.在以靛蓝染色的织物清洗中,要选择性地使用洗涤剂,进行点滴试验后才可使用,同时在存放过程中要做到避光、避免高温.  相似文献

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.  相似文献

华侨高等教育是我国高等教育独特而又不可或缺的重要部分,她的产生、形成、嬗变和发展经历了相当长的一段历史。在这段长期的历史进程中,民国时期是华侨高等教育兴起与发展的重要时期。国民政府将暨南学校升格为国立暨南大学,开辟了华侨高等教育新的纪元。政府对一所高校的举措,从一个重要侧面反映了当时社会政治、经济、文化和教育的状况。研究暨南学校走向国立暨南大学,华侨基础教育发展成为华侨高等教育的内在因素和外在条件,探讨侨务政策与华侨教育之间的关系,对于认识与改进今日之华侨高等教育有着很大的现实意义。  相似文献

六胡州古城址的发现及其环境意义   总被引:15,自引:0,他引:15  
本文在追溯唐代六胡州的建置与“灵、夏之间”行政沿革的基础上,通过对内蒙古、宁夏、陕西三省区交界处,即毛乌素沙地西南缘的实地考察,并依据考古与文献资料,初步确定了今鄂托克前旗与盐池县境内的六个唐代古城址与六胡州的对应关系。从古城址的时空分布格局、选址条件、人类活动方式等出发,阐述了六胡州古城址的环境指示意义。唐初六胡州北部已经有比较严重的土地沙漠化问题,而六胡州一带建城时因受早期沙漠化过程的影响,在局部地形部位可能分布有地表积沙。  相似文献

“诺维科夫报告”与冷战初期的苏联外交政策   总被引:1,自引:1,他引:0  
何伟 《世界历史》2006,2(2):29-36
1946年苏联驻美大使诺维科夫撰写了一份题为《战后美国外交政策》的报告,这份报告在一定程度上反映了苏联政府对当时世界局势的判断,对冷战爆发前的苏联对外政策产生了某种影响作用。中外学术界对这份报告颇为关注,本文认为如果把诺维科夫报告视为苏联在战后初期外交政策的纲领性文件同凯南的“八千字长电报”相提并论是不确切的。  相似文献
