Strontium isotope analysis is applied in South America for the first time in order to investigate residential mobility and mortuary ritual from ad 500 to 1000. While Tiwanaku‐style artefacts are spread throughout Bolivia, southern Peru and northern Chile during this time, the nature of Tiwanaku influence in the region is much debated. Human skeletal remains from the site of Tiwanaku and the proposed Tiwanaku colony of Chen Chen have been analysed to test the hypothesis that Tiwanaku colonies, populated with inhabitants from Tiwanaku, existed in Peru. Strontium isotope analysis supports this hypothesis by demonstrating that non‐local individuals are present at both sites.  相似文献

This article deals with the question whether and how processes of policy diffusion can be examined with qualitative methods. More specifically, how can qualitative methods address the “twin challenge of interdependence,” namely the challenge to identify diffusion, on the one hand, and the challenge to discriminate between mechanisms of diffusion, on the other? I argue, first, that there are three distinct qualitative techniques that can be used, namely cross‐case analysis (often based on systematic case selection), within‐case process tracing, and counterfactual reasoning. I demonstrate how these techniques can be adapted to the study of policy diffusion. Second, a combination of these methods is the best practice, since they are largely complementary in terms of the twin challenge of diffusion. The discussion draws on numerous illustrations from recent qualitative policy diffusion studies. The article closes with some suggestions for further methodological development in the study of policy diffusion, including the combination of quantitative and qualitative methods.  相似文献

Lead isotope analyses of Early Bronze Age metal artefacts from the Aunjetitz (Ún?tice) culture in central Germany and Bohemia were determined in order to find out whether they could be related to ore sources of the Erzgebirge. Historical mining began only in the 12th century ad , but despite the lack of convincing field evidence it has frequently been suspected that this region was already being exploited in prehistoric times. For the determination of the lead isotope ratios, the new technique of multiple collector inductively coupled plasma mass spectrometry (MC‐ICP‐MS) was employed, which combines relatively easy sample preparation with highly precise and accurate measurements. The results show that there is still no evidence for prehistoric mining in the Erzgebirge, but the Rammelsberg deposit in the Harz Mountains might have supplied some of the copper. Mining of stream tin in the Erzgebirge remains a possibility, but no positive evidence can be extracted from the data.  相似文献

Ethnoarchaeological studies have longed served as a critical source of hypotheses, comparative data, and explanatory frameworks for archaeologists interested in describing and explaining ceramic production. In this paper, I lay out the central questions addressed by archaeologists studying craft production, discuss how ethnoarchaeology has contributed to our understanding of ancient production systems, and suggest avenues of further research that can benefit archaeological investigation of the organization of ceramic production.  相似文献

论文根据田野调查的经验,分析了马来西亚民间华文历史文献的类别,并从组织序列、历史序列两方面,探讨了马来西亚乡土历史的书写内容和方法,归纳其对方志研究的作用。马来西亚的史学乃至华人研究,除了少数几位民间文史工作者,一般皆以传统文献切入,学者下乡采集文献资料较少,故此民间华文历史文献的采集和研究工作可谓大有可为。除地方文化研究必须依托民间文献方克有成外,华人民俗文化的研究依赖民间文献之处更为显著。这两个领域恰好正是殖民政府和现今的国家机器较少涉入,乃至不闻不问、任其自行发展的地带。近一二十年随着国家经济发展,迅猛的城市化,无所不在的西化,许多地方特色在发展洪流中消失。因此,马来西亚的民间华文历史文献采集和研究有待进一步深入。  相似文献

以清代永定河芦沟桥志桩尺寸记录为骨干资料,结合近现代器测水文资料,使用分段建模的方法恢复了1766-2004年永定河芦沟桥断面的汛期径流量序列,序列表明永定河径流量在逐年尺度上具有极大的不稳定性,但其洪峰规模自19世纪以来不断减小,19世纪中期与20世纪初期是最为明显的丰水时段,而1920年代后径流量便明显萎缩,枯水期一直延续至现代。进入1920年代后,流量变化在18世纪后期至19世纪存在的30年准周期消失,水量变化呈现无周期特征。与太平洋年代际振荡指标PDO的比对发现,两者在30-40年尺度上具有明显的反相关关系,天然状态下,太平洋温度升高对应于永定河流域较为干旱的时段。海温异常造成的季风强度变化会导致华北地区降雨格局出现变化,进而影响到永定河芦沟桥以上河段的汛期水量,表明处于季风区北部边缘的永定河水系对于太平洋海温变动具有更大的敏感性。  相似文献

19世纪后半期迅猛发展的美国城市化,使美国社会经济生活出现全方位的变化。同时,人口高度密集的城市环境导致公共卫生问题恶化,出现所谓的卫生危机,从而促发了城市公共卫生改革。此后,在美国城市的环境治理和疫病防治方面都出现系列性变化,城市公共卫生开始走上正轨。在此过程中,政府开始直接干预公共卫生,大众卫生意识得以强化,为美国城市卫生事业留下了宝贵遗产。  相似文献

建国初期,中共在广州构建了一个过渡性的社会救助体系,在短短的4年内,广州市通过它救助了大量的失业者和城市贫民,基本上遏制了由于新旧转轨带来的社会危机,为新政权即将展开的社会主义各项建设奠定了基础.在救助理念和救助过程上,它体现了以往社会救助的一些特点,同时也反映了我党的诸多特色,诸如鲜明的意识形态性、广泛的群众参与性和严格的组织纪律性,隐隐约约闪烁着以统一调配为主要特征的计划时代社会政策的影子.  相似文献
