Exploring trade globalization in the long run: The RICardo project

Initiated in 2004, the RICardo project focuses on bilateral trade data of all the world's countries from the early nineteenth century to the eve of the Second World War. The project includes the construction of a database and the creation of a website. It is a pioneering work in the field of historical trade statistics that aims at providing easy-to-access research material to the scientific community and at attracting a wider public to the history of trade relationships. The article emphasizes the originality of the project and sums up its various aspects by reviewing previous trade databases, clarifying the main features of historical trade statistics, and describing the construction and use of the RICardo website.     

A third road to the past? Historical scholarship in the age of big data

Is a third passage to the past possible, beyond Elton's and Fogel's two roads of narrative history and scientific/quantitative history? One that would combine narrative history's focus on the event, on individuals and their actions, at a particular time and place, to scientific/quantitative history's emphasis on explicit behavioral models based on social-science theories? That is the question this article addresses. It illustrates a computer-assisted methodology for the study of narrative—quantitative narrative analysis (QNA)—that does just that. Based on the 5 Ws + H of narrative—Who, What, When, Where, Why, and How—QNA quantifies events without losing the event itself, without losing people behind numbers, diachronic time behind synchronic statistical coefficients. When used in conjunction with dynamic and interactive data visualization tools (and new natural language processing tools), QNA may provide a third unforeseen road to the past.

山东危山西汉墓出土陶器彩绘颜料研究

为研究山东危山西汉墓出土彩绘陶器颜料成分,采用偏光显微镜、显微拉曼光谱仪和扫描电子显微镜-能谱仪进行了分析。研究结果显示,危山汉墓陶器彩绘颜料有朱砂、铅丹、中国紫(汉紫BaCuSi2O6)、铁红、铁黑、白土等。中国紫颜料首次在山东省的发现,扩大了该颜料的使用区域,具有重要的考古学意义。另外,还在紫色颜料中分析出了BaCu2Si2O7蓝色晶体,这是继中国蓝中国紫之后的又一重大发现。     

The application of structured‐light illumination microscopy to hydrocarbon‐bearing fluid inclusions

Structured‐light illumination (SLI)‐based microscopy offers geologists a new perspective for screening of hydrocarbon‐bearing (HCFI) and small aqueous fluid inclusion (AFI) assemblages. This optical‐sectioning technique provides rapid, confocal‐like imaging, using relatively simple and inexpensive instrumentation. The 3D fluorescent images of HCFI planes and large single HCFIs permit the visualization of the relationships between HCFI assemblages, examination of HCFI morphology, and volume estimates of the fluorescent components within HCFIs. By the use of normal white light illumination, SLI image capture, and varying acquisition time it is also possible to image AFI because of the random movements of vapour bubbles within the inclusions. This allows the near‐simultaneous visualization of hydrocarbon and AFI which is of significant importance for the study of sedimentary basins and petroleum reservoirs. SLI is a unique and accessible 3D petrographic tool, with practical advantages over conventional epifluorescence and confocal laser scanning microscopy.

Viking age horse graves from Kaunas region (Middle Lithuania)

Balts' territories have one peculiarity—large amounts of horse bones are found in burial grounds. This phenomenon is typical to the Prussians (5th–11th centuries) and Lithuanians (Kaunas region 8th–11th centuries) Horse burials of the 8th–11th centuries reflect the archaeological culture of Middle Lithuania most significantly. Several horse burial types have been defined on the basis of individuals; osteological signs and the archaeological data of the horse remains. A typical horse grave is when the whole horse was buried. Sometimes only a head or a head with forelegs, or scattered horse remains are found in a burial. The large number of burial grounds with an abundance of horse graves testifies to a very expressive ritual of horse offering in the Balts' region. On the basis of the data obtained, we determined that mostly 4–10 year old horses were buried in the grounds of Middle Lithuania. From the bone measurements, it has been determined that the length of metacarpals ranges between 180 and 216 mm (the average length 193.1±0.99 mm); the length of metatarsals between 218 and 253 mm (average length 233.9±0.73 mm).These data demonstrate that horses of different types were buried in Marvelė and Veršvai burial grounds (wither height 120–136 cm). A certain number of the larger horses (wither height 136–144 and 153 cm; length of metacarpals 210–222 mm) might not have belonged to local breeds. We have come to the conclusion that the most similar horse skeletons (according to the osteometric data) were found in Latvia. Copyright © 2001 John Wiley & Sons, Ltd.     

多源数据结合的城市生活空间质量评价——以南京为例

在当前我国社会经济转型的背景下,城市生活空间质量成为居民、学界与政府关注的焦点。采用多源数据,拓展了已有城市生活空间质量的评价维度与评价方法,从舒适性、便利性、健康性、安全性、社会性五个维度构建了评价指标体系,并通过GIS空间分析方法,以南京为例进行了生活空间质量评价并识别其空间分布规律。实证分析表明：①南京的城市生活空间质量存在着明显的空间分异。高质量生活空间呈现明显的等级集聚特征,主中心位于核心区周边1-3 km的圈层,低质量生活空间总体分布较为分散。②在构成生活空间质量的五个维度中,舒适性和社会性的发展质量呈现由城市中心向外围递增的趋势,便利性的发展质量呈现由城市中心向外围递减的趋势,健康性受城市环境质量分布趋势的影响,呈现由西北向东南递减的趋势,安全性的高值集聚不显著而低值集聚于城市中心区。
