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.     

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

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.     

Bayesian Parameter Identification and Model Selection for Normalized Modulus Reduction Curves of Soils

This work develops a procedure that involves the use of Bayesian approach to quantify data scatterness, estimates the optimal values of model parameters, and selects the most appropriate model for the construction of normalized modulus reduction curves of soils. The proposed procedure is then demonstrated using real observation data based on a set of comprehensive resonant column tests on coarse-grained soils conducted in the study.     

Does clean air increase the demand for the consumer city? Evidence from Beijing

Cities offer a large menu of possible employment and leisure opportunities. The gains from such consumer city leisure are likely to be lower on more polluted days. We study the association between daily consumption activity and outdoor air pollution in China and find evidence in favor of the hypothesis that clean air and leaving one's home for leisure trips are complements. Given the high levels of air pollution in cities in the developing world, regulation induced improvement in environmental quality is likely to further stimulate demand for the consumer city.     

尉氏元代壁画墓札记

尉氏县张氏镇壁画墓在最近的报道中被断为宋代。本文结合相关考古资料,从墓葬形制、壁画布局、仿木结构、人物服饰、墓门题记等几个方面进行对比分析,将该墓订正为元代。又依据文献记载和图像资料,对该墓壁画中“曾参行孝”和“焦花女哭麦”两组孝子图加以考证。并进一步梳理了考古所见二十四孝图像,发现其组合形式在宋金时期比较稳定,而元明时期则逐渐转向多元。     

What can pollen grains from the Terracotta Army tell us?

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.     

Can the Raman spectrum of anatase in artwork and archaeology be used for dating purposes? Identification by Raman microscopy of anatase in decorative coatings on Neolithic (Yangshao) pottery from Henan,China

Scanning electron microscopy/energy dispersive X-ray analysis has earlier shown that the white background layer (slip) on painted pottery sherds (Yangshao culture, Henan, China, 4200 BC) is composed of kaolinitic clay containing titanium in the assumed form of TiO₂ at just 1 wt%. The same samples of white slip have now been studied by Raman microscopy, revealing bands characteristic of anatase, but none from the majority species, the matrix of kaolinitic clay. These results highlight the extraordinarily intense Raman scattering from even trace amounts of anatase and thus the need to recognise that, although the colours of archaeological artefacts are almost always determined by the nature of the matrix, the Raman spectrum may be determined by a highly scattering trace component such as anatase. The significance of anatase as a potential date-marker pigment on works of art and archaeological artefacts is discussed.     

一批流散海外的吐蕃文物的初步考察

吐蕃文物曾通过不同途径流散于海外,主要包括金银器与织锦。从中反映出吐蕃作为七世纪以来兴起于青藏高原的强大政治集团与唐、粟特、萨珊波斯等都有着密切的文化联系,并已形成具有自身特色的金银器制作风格;以对兽纹为主题的织锦是吐蕃人最为喜好的"番锦"之一,有可能为粟特锦,也有可能为包含粟特锦、波斯锦等中亚风格在内的"胡锦"。吐蕃银器上的纹饰更是多见于吐善时期的装饰性图案当中,并且影响到以后的藏族艺术。     

《唐大和上东征传》鉴真携带品辨正

真人元开(Omino Mihune)撰于779年的鉴真传记<唐大和上东征传>,有多种写本、刊本传世.1762年以后的刊本,流传颇广,其对文本的字词误读甚至影响到今天.本稿依据现存日本的古写本及多种刊本,对鉴真第二次东渡携带品的误读进行辨析、纠谬,指出在研究域外汉籍中写本的重要性.
