The primary objective of relative dating techniques is to determine a reliable sequence of archaeological deposits. This task becomes more difficult whenever our research steps beyond individual sites to the study of intercommunity relationships because we need to develop some means of associating unconnected deposits in time. Radiocarbon dating, as a stand-alone method, cannot always be used to draw reliable correlations between sites. The relevance of archaeological dates, including absolute dates, relies ultimately on the determination of artifact or sample associations and their respective superpositional relationships. The Unitary Association Method of Relative Dating is an alternative to seriation methods that is less susceptible to spatial variation and offers analytical strengths needed for regional chronological analyses.  相似文献

The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.  相似文献

As social and cultural contexts change and globalization spreads, the number of transnational-marriage migrants mainly from Southeast Asia has increased in Taiwan. Using institutional ethnography, this article investigates the roles of local non-governmental organizations (NGOs) and projects aimed at helping foreign spouses to adapt to their new life. I mainly elaborate that NGOs emerge as important actors in assisting and empowering transnational spouses to ‘become locals’. In empowerment projects, foreign spouses are given a voice to elaborate themselves. However, this article elaborates that these projects are a scheme of education to shape each such migrant into a proper ‘Taiwanese wife/mother/daughter-in-law’. Also, these projects particularly promote ‘exoticism’ of migrants and become key sources of how local people understand the images of ‘foreign spouses’. As a result, though NGOs play positive roles in empowering foreign spouses, we need to be aware that NGOs’ efforts may ironically become a mechanism to strengthen transnational spouses’ gender roles and cultural stereotypes.  相似文献

Informed by Didier Fassin’s concept of humanitarian government, this article reveals a distinct pattern of secret care provisions imposed under Stalin by the secret police and its successor agencies (NKVD, MVD) first to the peasant children displaced by class war and the famine of 1932–33, and then to the children made homeless by the Great Terror and the 1940s’ national deportations. The article also identifies the under-researched reception centres as crucial sites for both administering emergency assistance and establishing the social classification necessary to apply these discriminatory measures. Affected by the decreasing faith in their possible socialist rehabilitation and lack of any official display of compassion, these children’s lives appeared even less worthy of saving in the course of major emergencies. These findings challenge the official Soviet view of the existence of a universal childhood worth protecting, which guided the first socialist country’s intervention to save other children nationally and internationally.  相似文献

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.  相似文献

类型学作为认识工具,只涉及科学发现与检验的原理和逻辑,并不涉及具体事实。考古类型学由分型和分式两部分构成,分型即分类,分式即排序。本文借《元君庙仰韶文化墓地》和《试论殷墟文化分期》两篇论著,以集合论的原理和知识说明分类的逻辑,得出穷尽性、排他性、同一性三条原则;以函数的思想说明排序的逻辑,得到同一性原则。  相似文献

The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.  相似文献

Despite the widespread attention to capital investments in land and property around the globe, the active re-regulating role of the neoliberal state in processes of “accumulation by dispossession” remains underexplored. Through an in-depth look at the dispossession of highly fragmented and loosely regulated private land for windfarm investments on Crete’s eastern corner, Sitia, this paper re-affirms the political nature of the forcible appropriation of land for large-scale investments; dissects the specific mechanisms in which the state dispossesses land on behalf of investors and promotes the forcible appropriation of land from below; and problematises the dialectic relationship of both rupture and continuity between crisis and inherited, path-dependent relations embedded in land. The transformation of Sitia’s loosely regulated, informal relations on land is made possible through the mobilisation of the state’s bureaucratic and normalising powers, which redefine the concept of forest and dispossess through classifying land as such.  相似文献
