The Global Economic Crisis and China's Foreign Trade

Two noted academic specialists on China's economic geography are joined by a research assistant to examine the impact of the current global economic crisis and recession on China's trade with the rest of the world. Relying on statistics collected by the country's customs administration through the first half of 2009, the authors identify and analyze trends in China's imports and exports (detailing countries of origin and destination) as well as balance of trade. They also develop and present an input-output model in order to gain a more precise understanding of the country's trade dependence (both before and during the crisis) than afforded by analyses based on conventional statistics, and explore some of the implications of the decline in trade on levels of domestic unemployment.     

日本汉字的近代演变、动因及启示

本文在参考现有国内外学者最新研究成果的基础上,考察日本汉字存废和限制用字的历史过程及最新进展。日本历史上的文字改革始于明治维新,二战以来限制汉字使用,普通常用汉字被严格限制在一个有限范围内并且在数量上长期保持稳定。近年来则由于技术和社会的发展正面临着新的挑战。本文试图通过探讨日本汉字规范化过程的特点和困难,揭示其背后的社会文化动因,以期为我国目前正在进行的汉字现代化和标准化工作提供参照。     

Estimation of adult skeletal age‐at‐death: statistical assumptions and applications

We examine the statistical assumptions underlying different techniques of estimating the age‐at‐death of a skeleton from one or more age indicators. The preferred method depends on which property of the distribution of the data in the reference sample is preserved in the skeleton to be aged. In cases where the conditional distribution of age given indicator is preserved, we provide ‘look‐up’ tables giving essentially unbiased age estimates and prediction intervals, using a large reference sample and the auricular surface and pubic symphysis age indicators. Where this assumption is violated, but the conditional distribution of indicator given age is preserved, we find that an alternative model which attempts to capture the biological process of development of an individual has some attractive features, which may make it suitable for further study.

Response to Wet Season Rainfall of an Alluvial Aquifer System in the Lower Herbert Floodplain,Queensland, Australia

Australia is one of the world's largest exporters of raw sugar. The lower Herbert River floodplain, one of the four main cane growing areas in Queensland, is subject to extremes of rainfall. Some areas are prone to waterlogging, which can lead to reductions in cane and sugar yields. This paper examines the risk of waterlogging and the role of surface drains in the Ripple Creek area, a subcatchment of the lower Herbert River floodplain. Following above‐average rains at the onset of this study, a perched water table developed and remained for the duration of the 19 month study. The responses of the perched watertable and a deeper semi‐confined aquifer following rainfall are examined. The rapid response of the perched water table following rainfall is attributed to the shallow depth of the water table, with soil properties exerting a dominant influence on hydrograph response. In the second year of the study, after above‐average rainfall, the water table of the deeper aquifer was on average 1 m higher than during the former months of the study. This trend, however, did not occur in the perched water table, and this is attributed to the efficiency of the surface drainage network.     

Beyond the Visible: Combined Neutron and X‐ray Imaging of an Altar Stone from the Former Augustinian Church in Fribourg,Switzerland

An altar table from the former Augustinian church in Fribourg (Switzerland) was studied by means of neutron and X‐ray imaging to investigate the embedded reliquary. The neutron transmission images showed that the sepulcrum contained three objects showing high contrast and high attenuation. As the particles were almost invisible in the X‐ray image, it was assumed that they were organic material. Comparative measurements on reference samples of materials possibly contained in such a reliquary (bone, teeth, leather, incense and parchment) suggest that the particles are bone fragments. Besides an assessment of the content, the results from the neutron investigation allowed a proposal of the probable geometry (i.e., shape and dimensions) of the sepulcrum.
