19世纪70年代的英国农业危机及其影响

１８７３年,资本主义世界爆发了一次空前严重的世界性经济危机,它标志着自由资本主义发展到顶点并开始向垄断资本主义过渡,从而使１９世纪７０年代成为资本主义发展史上具有转折意义的关键时期。英国这个在资本主义世界一直处于中心地位的国家,在这次危机中未能幸免,...     

21世纪的"海洋破碎带"

本简析了海洋的争夺史,在此基础上提出了本的中心议题—21世纪的“海洋破碎带”。探析了“海洋破碎带”形成的七大因素,即：①海洋霸权主义对海洋国际贸易通道的争夺;②国际间对海洋国土的争夺;③海洋生物资源的争夺;④海洋矿产资源的争夺;⑤南极大陆的争夺;⑥海军军备竞赛;⑦海缘政治形势日益恶化。阐释了21纪“海洋破碎带”分布的海域。最后指出,中国不仅是一个陆地国家,也是一个海洋国家,中国的海上安全已近底线。为此,中国必须树立新的海洋观念,建立强大的海军,保卫国家的每一寸海洋国土。     

大汶口文化的骨牙“雕筒”

大汶口文化的骨牙“雕筒”是大汶口文化中最具代表性的器物之一。然而对于它们的用途和功能却一直众说纷纭,尚无定论。本文通过对其形制以及它们在墓葬中安放的位置及与相关器物的关系之考察,确认不同形制的骨牙“雕筒”具有性质不同的用途和功能。其中A、B型“雕筒”可能是一种与宗教有关的器具,而C型“雕筒”应是套在斧钺(锛)类器物木柄尾端的饰件——即镦。不论是作为宗教器具还是礼仪用具(附件)的“雕筒”,显然都是当时社会中具有特殊身份的人们才能拥有的。环顾各地的发现,类似大汶口文化骨牙“雕筒”这种特殊随葬品的出现,当系社会发展到一定阶段的必然产物,从而得以管窥当时社会权力在时间和空间上的分布状况。     

大数据背景下国内人文地理研究进展与方法审视

通过梳理人文地理领域杂志近年大数据文章解释其与大数据应用的关系，强调其应用给人文地理学研究带来机遇和挑战：①大数据作为研究方法，不能代替传统人文地理研究范式，而是对现研究方法的补充。大数据和小数据需对话交流；②大数据本身是一种话语权，嵌入人文地理研究系统。保证人文地理学多样性，避免过度依赖大数据，需在批判角度审视和运用；③需关注大数据对于人文地理学研究方法和思想的影响；④运用大数据解读地理和空间过程复杂性的同时，应看到大数据应用对公共服务的潜力，思考其结果如何更好的服务社会。     

Elemental Characterization by EDXRF of Imperial Longquan Celadon Porcelain Excavated from Fengdongyan Kiln,Dayao County

A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy‐dispersive X‐ray fluorescence (EDXRF). The results indicate that the contents of TiO₂ and Fe₂O₃ in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K₂O, Fe₂O₃ and TiO₂ are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.     

Measuring Spatial Autocorrelation of Vectors

This article introduces measures to quantify spatial autocorrelation for vectors. In contrast to scalar variables, spatial autocorrelation for vectors involves an assessment of both direction and magnitude in space. Extending conventional approaches, measures of global and local spatial associations for vectors are proposed, and the associated statistical properties and significance testing are discussed. The new measures are applied to study the spatial association of taxi movements in the city of Shanghai. Complications due to the edge effect are also examined.     

2015尼泊尔地震后加德满都谷地世界文化遗产破坏特征

2015尼泊尔地震对加德满都谷地的世界文化遗产造成不可估量的损失。为了探究谷地文化遗产震害整体分布特征,对谷地世界文化遗产建筑的震害状况开展实地调查,划分了三类文化遗产震害等级标准,形成了六处世界文化遗产的震害图并对其进行统计分析,加德满都、帕坦和巴德岗三处杜巴广场震后保存基本完好的文化遗产建筑占各自总数的39.5%、53.3%、50%,斯瓦扬布纳特寺、昌谷纳拉扬寺和博达哈大佛塔主体保存基本完好,附属建筑不同程度地破坏。加德满都、帕坦和巴德岗三处杜巴广场地层的松软沉积层放大地震效应使建筑严重破坏,斯瓦扬布纳特寺、昌谷纳拉扬寺震害主要受地形特征影响。考察成果为我国同类遗产建筑的抗震防护提供参考。     

Neighbourhood food environments revisited: When food deserts meet food swamps

This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources.     

Behind the Façade of the Rites Controversy: The Intriguing Contrast of Chinese and European Theism

The Chinese rites controversy of the seventeenth and early eighteenth centuries has been often studied, but hitherto mostly as a quasi-linguistic-and-technical dispute between the followers of Matteo Ricci, the legendary founder of the Jesuit China mission, and his many different enemies in the Catholic Church. In reality the involved debate was much more complex than that at every turn. To show this and more, this article takes a close look again at how and why Chinese terms and customs came to figure in Ricci's proselytising work in China, how they were challenged both inside and outside the Jesuit China mission, how the Chinese reacted and why, and what the debate revealed about the intriguing contrast of Chinese and European theism.
