John W. K. Harris 《African Archaeological Review》1983,1(1):3-31
In the time interval between approximately 2.5 million years and 1.5 million years ago and against a background of changing environmental conditions and the emergence of highly diversified populations of early hominids, the earliest archaeological occurrences have been documented from a number of localities in the Rift Valley of East Africa. These have been attributed to the Oldowan Industrial Complex. More recently, broadly comparable archaeological occurrences have been discovered from Hadar and the Middle Awash located in adjacent areas of the Afar, in Ethiopia. This paper summarizes the age, context and characteristics of these occurrences and offers preliminary comments on their contribution to greater understanding of early hominid adaptive patterns of behavior. 相似文献

AbstractA regional perspective is desirable in the archaeological study of prehistoric complex societies. Over the past decade systematic surface survey has provided such a perspective for the period between 1100 B.C. and 1520 A.C. in the Valley of Mexico. This paper attempts to illustrate something of the utility of regional settlement pattern analysis as one phase of a long-term research program aimed at explaining cultural evolution in precolumbian Central Mexico. 相似文献

Obsidian artifacts from the Melka-Konture site about 50 km south of Addis Ababa span the period from Oldowan to Late Stone age. A number of specimens from different levels have been examined petrographically and for their chemical compositions. All prove to be alkali rhyolite obsidians of virtually identical composition and petrographic character, differing only in degree of devitrification and hydration. They belong to Group 1g of Renfrew et al. (1966) and it is almost certain that their source is the nearby obsidian quarry at Baltchit. This seems to have been opened in a short flow which appears to be unrelated to the large extinct Recent volcano, Wachacha, which lies to the north-west. 相似文献

产业融合:旅游业发展趋势的新视角 总被引:27,自引:0,他引:27
本文从产业融合的理论视角对当前旅游业多业态现象进行了分析,指出旅游业正在与其他服务业、制造业和农业进行产业融合,产业价值链不断被解构和重组,并表现出生产性现代服务业特征。本文不仅对这种产业融合动因进行了具有旅游特质性的剖析,对融合情况进行分类,还指出其本质是一种创新。融合产生的效应反映在多方面:行业竞争格局发生演变,出现系统集成商和具有双边特征的平台企业,非物质资源取代自然资源推动旅游业发展,旅游业出现模块化迹象,跨行业人才成为稀缺资源等。 相似文献

台湾大学《考古人类学刊》是我国台湾地区刊登考古学文章最为集中的期刊,通过对其1953-2006年发表的学术论文和作者的统计分析,可以审视自创刊以来台湾考古学的发展及其成就.该刊刊载论文以民族学、考古学和人类学三大学科为支柱,其中民族学类论文为最大宗,考古学类次之,人类学文章紧随其后.台湾考古经历了三个阶段:20世纪50年代对日据时期日本学者工作的梳理和总结,再到60年代以中原(殷商)考古为主导,逐步过渡到70年代以后台湾地区考古的本土化和重新定位. 相似文献

The 2000 Presidential election was plagued by butterfly ballots and ‘pregnant chads’. Electronic voting systems, lacking verifiable paper trails that are subject to possible fraud, promise to wreak havoc with the 2004 Presidential election. There is a great diversity of systems of voting technology in the 50 states: from paper ballots, lever‐operated machines and punch cards to optical scanners and electronic systems. Associated with each technology is an estimated error rate. The underlying theory of this paper was set forth by William F. Ogburn in his famous book entitled Social Change, published in 1922. Dividing culture into material and non‐material elements, Ogburn argued that non‐material elements lag behind material elements. His explanation for this lag is that technology, which underlies material culture, changes at a faster rate than elements of non‐material culture. Obgurn did not contemplate the possibility of a reverse lag, viz., technology lagging behind non‐material culture. In analyzing the anomalous relationships between voting technology, political institutions and legal institutions, a striking instance of a ‘reverse cultural lag’ is discerned. To eliminate the phenomenon of the reverse cultural lag, there is a need for a federally‐funded program of a uniform, state‐of‐the‐art voting technology, plus an amended Help America Vote Act, to implement the innovations in the 3,114 counties. The complex problems reviewed in this paper point to a vexing question: how do we educate an electorate in a democratic society—such as the United States in the twenty‐first century—to be responsible for ensuring that periodically‐elected representatives implement the will of the people? 相似文献

地名是人们在社会生活中给地理实体、行政区域或地点起的名称,地名往往带有强烈的延续性和稳定性,因而能够比较完整地保留命名时所反映的文化内涵。本文将粤东北山区梅州乡村地名为解读对象,探讨地名与生态环境,山区开发,地名与族群关系,地名与历史人物、历史事件,地名与军事设施及经济活动等的关系,以期再现客家聚落名称所蕴涵的丰富人文因素。 相似文献

Andreas Faludi 《European Planning Studies》2001,9(5):663-675
As a strategic document, the European Spatial Development Perspective (ESDP) wants to be 'applied' rather than 'implemented'. Rather than giving shape to spatial development, application is the shaping of the minds of the actors in spatial development. The latter are not passive recipients of messages. They actively explore options, reinterpreting messages on the way. Conformance of outcomes to intentions cannot be assumed. Application is not a separate phase either. Application includes making new working arrangements and elaborating planning documents to make them fit emergent situations. Judging from the ESDP and from how its ideas are being pursued, its makers are well aware of this. Research into the application of the ESDP in the north-west metropolitan area (NWMA) Interreg IIc programme confirms this. So the ESDP may be anything but a paper tiger. 相似文献

Extended research covering an area of approximately 300 sq km centered on the ancient metropolis of Aksum has revealed a coherent
sequence of development in stone tool production and use spanning most of the last millennium BC and the first millennium
AD. It has provided new evidence of the presence of multiple independent lithic traditions in the Pre-Aksumite period, and
of Aksumite social and economic organization. This paper summarizes the results of the detailed study of a large corpus of
excavated and surface-collected lithics, emphasizing their functional characteristics.
Résumé De vastes recherches couvrant sur une superficie d’environ 300 kilomètres carrés et concentrées sur l’ancienne métropole d’Aksoum ont mis à jour une série cohérente de développements dans la production et l’utilisation d’outils de pierre au cours du dernier millénaire avant J.C. et du premier millénaire après J.C. Ces recherches ont fourni de nouvelles informations sur la présence de multiples traditions lithiques indépendantes durant la période pré-aksoumite, et sur l’organisation sociale et économique des Aksoumites. Cet article présente les résultats d’une étude détailée portant sur un large répertoire de vestiges lithiques recueillis au cours de fouilles et collectes de surface, et met en exergue leurs caractéristiques fonctionnelles.相似文献

Whilst the deadline for achieving the Millennium Development Goals (MDGs) looms large, the outcomes so far have been mixed. This article examines the policy logic that ‘good governance’ leads to poverty reduction, which has been adopted by international agencies in pursuit of the MDGs. This causal relationship is examined through an empirical panel‐data estimation using Worldwide Governance Indicators and the poverty headcount ratio in ninety‐eight countries. The empirical evidence does not support the hypothesis that good governance leads to poverty reduction. Good governance alleviates poverty only in middle‐income countries, not in least developed ones. These findings point to the necessity to devise policies that address poverty directly, rather than through indirect instruments, and highlight the urgent need to address structural inequality in developing countries. 相似文献
