Study on the strontium isotope standard in pig teeth excavated from Zaoshugounao site,Shaanxi Province of China

In archaeology, strontium isotope analysis is developing into an efficient scientific technique for tracing the movement of prehistoric humans and animals. Determining the local bioavailable ⁸⁷Sr/⁸⁶Sr ratio range is the key to distinguishing whether the human or animal is indigenous to the local area. It has been shown that the ⁸⁷Sr/⁸⁶Sr ratio in the enamel of pigs can be an excellent sample to determine the range of local strontium isotope ratio at the site. However, pigs may not be all local at the site, and there is no special study on whether pigs’ different ages and tooth types impact the local strontium isotope characteristics. In this paper, the tooth enamel of 19 pigs from the Zaoshugounao site for strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) by multicollector–inductively coupled plasma mass spectrometry. There were no significant differences in ⁸⁷Sr/⁸⁶Sr ratios of local pigs at different months and different molar types, which did not affect the determination of the local strontium isotope standard. Based on the local strontium isotope ratio range (0.711056–0.711476), we found that five pigs were non-local. The Jing and Wei river basins (in Guanzhong basin) and northern Shaanxi are likely sources of non-pigs.     

Police and Politics in Aesthetics-Based Urban Governance: Redevelopment and Grassroots Struggles in Enninglu,Guangzhou, China

Rancière's theorisation of police, politics, and aesthetics offers an illustrative framework to understand urban (re)developments. While extant works have examined separately the art of governing through aesthetics and the political subjectivities of those having no part in the frame of visibility and intelligibility, this study argues that hegemonic aesthetic regime and bottom-up aesthetic practices can be mutually constitutive and reside in relationships of co-existence and mutual negotiation. Drawing on over a decade's investigation in Enninglu, a neighbourhood district in Guangzhou that underwent several rounds of political struggles related to redevelopment and conservation, we reveal how local residents negotiated aesthetic norms enacted by the state. Particular attention is paid to the interactions between the aesthetic regime imposed by the state and grassroots people reclaiming their own aesthetic sensibilities, culminating in a contingent, inconclusive, and “impure” space of politics. Both political subjectivities and aesthetic norms are redefined ongoingly in this process.     

A Minimax Method for Finding the k Best “Differentiated” Paths

In real-world applications, the k-shortest-paths between a pair of nodes on a network will often be slight variations of one another. This could be a problem for many path-based models, particularly those on capacitated networks where different routing alternatives are needed that are less likely to encounter the same capacity constraints. This paper develops a method to solve for k differentiated paths that are relatively short and yet relatively different from one another, but not necessarily disjoint. Our method utilizes the sum of a path's distance plus some fraction of its shared distance with each other path. A minimax algorithm is used to select the path whose largest sum of length, plus shared length vis-à-vis each previously selected path, is as small as possible. We present computational results for the Chinese railway system, comparing the paths generated by a standard k-shortest-path algorithm with those from our new model.     

Tracing the origin of Chinese early white porcelain in the late sixth century—evidence from Xing kiln

As the criterion used by archaeologists for determining early white porcelain is quite ambiguous, the origin of Chinese white porcelain remains a point of disagreement. In this study, we systematically investigate 61 typical Xing porcelains of the late Northern dynasties to the early Sui dynasty (550–600 CE) using spectrophotometer, X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD), and analyze the differences between early white porcelain and celadon of Xing kiln in terms of their whiteness and raw materials characteristic. The results show that early white porcelain is a new type of ware that differs from celadon, which can be distinguished by whiteness, with a whiteness greater than 8% being early white porcelain and a whiteness less than 8% being celadon. It is assumed that the ancient potters created the whiter wares based on celadon by improving the glaze and selecting new raw materials for the body, but the production of this type of ware was short lived and subsequently refined in the Sui dynasty (581–618 CE) owing to the limited improvement in whiteness.     

韩国迁都宜阳、阳翟考辨

从战国初年的历史形势和韩国的发展战略出发,考虑韩国灭郑的军事策略,结合考古材料,韩国迁都宜阳、阳翟的记载应是可信的。对文献记载的混乱现象应予以全新解读:韩国迁都宜阳、阳翟的时候,平阳作为政治中心在继续使用。换言之,韩国在保持平阳都城地位的同时,迁都宜阳、阳翟,以此来服务灭郑的军事战争。宜阳和阳翟是具有浓厚军事色彩的临时性都城,带有战时陪都的性质。     

伪色诺芬《雅典政制》史料价值初探

伪色诺芬《雅典政制》作为公元前5世纪后期雅典的历史文献,对于研究雅典政治状况、原提洛同盟"盟邦"与雅典的关系以及探析民主政治的实质具有重要的史料价值。作者主要从平民的权利、海上霸权两个方面论述雅典民主制保持完好的原因,评述"盟邦"主权遭到雅典侵夺的历史事实,从而证明雅典民主制乃是建立在全体雅典人对非雅典人剥削、奴役基础之上的。当政者所采取种种强化民主的措施,其目的都是为了维护雅典人的根本利益。     

试论《武王践祚》的文本流变

《上海博物馆藏战国楚竹书》(七)所收《武王践祚》,实为两种战国"简本"(甲本和乙本)的合抄。传世本则是参考了这两种简本,合编整理而成。与甲本相比,乙本在叙事及文字上更接近于原始的记录,成文应早于甲本。但甲本与乙本之间并没有直接的文本传承关系,应是两系文本发展的不同形态。参照乙本,可以推测《武王践祚》的原初结构,并不包括武王勒铭段。从文献体裁及文章内容看,甲本及传世本的这一段文字,应是合编自其他文献。《武王践祚》三个本子的比较研究显示,早期文献在流传过程中,不仅存在着文字的增饰、丢失与改动等现象,同时还存在着同种文献不同形态的合编整理甚至是不同文献的合并现象。这对我们认识早期文献形成及流传的特殊性,并进而讨论早期文献的史料价值,无疑具有重要的参考意义。

An analysis of spatial patterns of toponyms in Guangdong,China

The unique geographical environment and the historical waves of immigration of the northern Han Chinese to the Lingnan region have contributed to the development of a complex and unique culture in Guangdong Province. Four ancient ethnic groups, the Zhuang, Cantonese, Hoklo and Hakka, have resided in this area for centuries. As an important part of local culture, toponyms often survive changes in history and can reveal the temporal differences between the past and present in landforms and the spatial differences in the distribution of different ethnic group populations. In this study, two goals were sought: (1) the adoption of spatial smoothing and interpolation methods to reveal the spatial patterns of the Zhuang, Cantonese, Hoklo and Hakka toponyms based on comparisons among the proportions of those who speak various languages and (2) the investigation of the differences among toponymic layers under regional environmental conditions and the influences of geographic factors using an independent samples t-test and a binary logistic regression.
