The provenance of more than 2200-year-old terracotta warriors and horses in the Qin Shihuang Mausoleum is still a mystery, even though some researchers have inferred that the terracotta figures were produced near the mausoleum. The sporomorphs (pollen and spores) extracted from terracotta fragments of a warrior and a horse and compared with those obtained from soil samples from the Qin Dynasty layer in Pit No. 2 of the Qin Shihuang Mausoleum indicate that the pollen spectrum from the terracotta horse is different from that of the warrior, but similar to the local soil samples. Herbaceous pollen was dominant in the warrior sample, while arboreal pollen predominates in the horse and soil samples. Palynological evidence suggests that the terracotta horses were produced at a locality near the mausoleum, while the warrior came from a site which was further afield. 相似文献

Temporary consolidation is widely used to protect delicate artefacts or other fragile relics in art conservation. Although cyclododecane is extensively accepted, the safety‐related issues have become an increasing concern and its short working time is always annoying. Inspired by its low melting point, polar structure, well‐established safety profile, easy local availability and low cost, we propose menthol as a new temporary consolidant on the new excavation site of Qin Shihuang's Terracotta Army. In this paper, we offer a preliminarily exploration of the kinetics of menthol sublimation on two different matrices, its residue after volatilization, its penetrability and distribution in simulated terracotta samples, as well as other important properties in the laboratory. The results obtained from these tests reveal that the sublimation of menthol can be a zero‐ or a first‐order process, depending on the porosity of the matrices, and its best operational temperature resides in the range of 60–80°C. Finally, two field cases at the archaeological site of Qin Shihuang's Terracotta Army are presented to show that menthol is a very effective temporary consolidant. 相似文献

Ongoing debates over the significance of specialized production in ancient political economies frequently hinge on questions of whether elites or commoners controlled craft manufactures and whether the material or ideological import of these production processes was more significant in deciding power contests. Though long recognized, such queries were traditionally answered in relatively straightforward economic terms. Recently, these time-honored approaches have been questioned. An ever increasing number of authors are promoting varied takes on the causal linkages between political forms and processes, on the one hand, and patterns of production, distribution, and use of craft goods, on the other. The literature generated by these discussions is extensive, vibrant, and often confusing. Rather than trying to synthesize all reports and essays dealing with specialized manufacture, this paper highlights general interpretive trends that underlie and structure current debates. The concluding section offers suggestions for how studies of relations among crafts, power, and social heterogeneity might be pursued profitably in the future. 相似文献

This paper argues for a conception of art as an embodied and creative material practice. It draws on research conducted with seven professional ceramic artists who deal with landscape in their work to explore their processes of art-making through interview and (filmed) observation. It demonstrates the distributed range of embodied and relational more-than-artistic practices which inform how landscape is encountered, known and ultimately represented. It argues that artists’ self-expression in art is based upon material, social and political knowledges which interweave in artists’ lives. By studying ceramicists’ making this paper demonstrates both the non-conscious skill and the conscious technical knowledge needed to make art. It shows chance to have a triple role in practices of making, as something to work alongside, to work against and to draw on as a creative resource. This paper both argues for and demonstrates the value of an approach to art-making that frames it as a complex of both conscious, socio-cultural, technical knowledges and non-conscious skills which together (in)form works of (ceramic) art. 相似文献

Ever since the pits of terracotta warriors and horses in China were discovered and opened to the public, a number of questions remained unsolved: what kinds of wood were selected for building the pits, how the wood was used in the pits' architecture and where was the giant volume of wood collected from? In this study, twenty pieces of charcoal specimens from Pit 1 and Pit 2 were examined with the Scanning Electron Microscope and identified as Abies, Tusga, Picea (all three genera in Pinaceae) and Phoebe (Lauraceae) woods. With the former works, it is concluded that the woods in the pits were mainly from the group of gymnosperms (95%) and few from that of angiosperms (5%). It is deduced that the wood in the pits was probably collected from the areas nearby. 相似文献

This paper discusses variation in the organization of ceramic production among family specialists who use a fast wheel technology in south-central Guizhou, China. There is considerable variation in intensity, output, and scale among potting households in two communities. The paper evaluates the utility of two kinds of potential material indicators for this variation: 1) spatial organization for different steps in production (forming vessels, preparing clay, drying vessels, firing), and 2) degree of vessel uniformity. Although degree of uniformity of vessels does vary with intensity for some dimensions, other factors such as experience of the potter and consumer demand need to be considered. Material features of production areas are more obvious indicators of variation in intensity and output. 相似文献

Jerash in northern Jordan was, despite a focus on its classical heritage, also active in the Middle Islamic period, but little is known about actual developments during this period. This study represents the first study on the Middle Islamic glazed pottery from the site using scanning electron microscopy energy‐dispersive spectrometry (SEM‐EDS) and thin‐section petrography. The results show that two production traditions existed, each with different provenances. The local production is characterized by a non‐calcareous ceramic body and the use of a high‐lead glaze coloured with iron and copper oxides, whereas the turquoise‐glazed samples, likely imported from Mesopotamia, have a calcareous ceramic body and alkali or alkali‐lead glaze. 相似文献

Phrygian Gordion was the political center of an influential Iron Age polity that extended across west central Anatolia during the first half of the 1st millennium BC. Though the borders of this polity remain vague a characteristic of the Phrygian “footprint” is the distribution of highly distinctive ceramics. The extent to which Gordion potters were the originators of these wares remains uncertain. In this paper we use Neutron Activation Analysis (NAA) to establish the local signature of predominantly Iron Age ceramics for this site by combining samples from several decades of excavation with an extensive regional sediment sequence. We also compare previous NAA work at Gordion to suggest that the formative stages of the Phrygian state appears to have involved a more extensive network of non-local specialist producers than previously thought. 相似文献

While improving the “hard” resources of the physical infrastructure is important to facilitating cross-border trade, studies of global supply chain logistics performance suggest that expanding the focus to include “soft” infrastructure resources will be critical for future gains. Border management is increasingly important to North American trade facilitation, yet little is known about what constitutes the soft infrastructure of border crossings or how to design and manage this infrastructure for improved performance. Hence, this study uses an exploratory research design to examine the nature and dimensions of the soft infrastructure of border crossings. The research relies on a grounded-theory analysis of primary data collected in an exploratory case study of two border crossings between Alberta, Canada, and Montana, US. 相似文献

ABSTRACTThe widely observed erosion of the policy capacity of governments and their public services is mirrored by decay in the practice and program capacity of community organisations. This capacity once depended on the practical expertise of a values-driven workforce employed in organisations focused on a social purpose. Governments relied upon this core competency to inform their approach to investment, program design and the delivery of community services, but this has changed. Social purpose in community service organisations have been frustrated by a preoccupation with funding models, procurement approaches and contract details at the expense of the delivery of outcomes. It has resulted in community organisations becoming subjects of service delivery rather than authors of it. The paper frames these dilemmas and provides a theoretical framework for community organisations to reposition from subjects to authors in the system. The paper takes the form of a reflective assessment from a practice perspective. 相似文献

ABSTRACT We document major changes in museum supply in China between 1996 and 2015. These years have seen the opening of many small, low budget and locally managed museums; an increase in the average size and expenditure of all museums; and significant investments in a few large and centrally managed superstar museums. Chinese people have access to larger and better museums and pay lower admission fees. Regional inequalities in museum growth are smaller than inequalities in GDP growth. We relate these findings with the small literature on Chinese museums and specifically the notions of soft power and cultural nationalism. 相似文献

七七事变前,日本即关注连云港的重要战略地位,并作了大量实地考察。徐州会战后,日本海军陆战队与华北方面军分别攻占连云港及周边的海州地区,并围绕连云港的支配权展开激烈争夺,几经调解,双方达成共同使用连云港的协议。这种双方共管体制的弊端不断显现,随后港口管理遂移交华北交通株式会社负责,实行"路港一体化"的运作方式,并接受华北方面军的指导和监控。日占期间,重点统制经营的连云港在华北港口布局中占据重要地位,煤炭、铁矿石等基础工业原料是港口主要出口物资,煤炭输出更在港口总吞吐量中占据绝对优势。 相似文献
