城市发展指数指引下的我国收缩区域初步评判

城市收缩在全球范围内蔓延，致使以增长为假设前提的区域经济增长模型受到极大挑战。本文以县域单元为研究对象，利用2000年与2010年各县域单元的社会经济数据构建城市发展指数，在其指引下对我国城市收缩状况做初步分析。研究表明：①在城市化的快速进程中，我国县域单元出现收缩现象，特别是县、自治县、自治旗、旗出现较多数量的收缩。②发生收缩的县域单元共261个，大多数为人口较少的中小城镇；西部地区分布较多，且收缩面积较大。③收缩的县级行政区表现出一些共性特征：人口数量和密度下降、老龄化加深、医疗卫生条件较差、经济发展缓慢，财政赤字严重。这一结果有助于初步了解我国收缩区域整体格局，并呼吁研究者和政策制定者尽快针对这一问题展开研究，促进区域可持续发展。     

A New Methodology and Classification System for Describing Three‐Dimensional Particle Formats: Application to Clastic Lithic Products of Archaeological and Geological Origin

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown.     

南方地区古建筑木结构的整体性残损点指标研究

古建筑木结构的残损点指标是对古建筑木结构进行结构安全评估和加固修缮设计的重要指标,目前主要依据1992年制定的《古建筑木结构维护与加固技术规范》(GB 50165—92)中的规定,为了对该规范中的构架整体性残损点指标进行验证和补充,本研究通过对南方地区传统的穿斗木构体系和抬梁木构体系的典型榫卯节点和构架的试验研究,得出两种木构体系结构的整体性关键残损点指标,并与GB 50165—92规范进行比较分析。结果表明:规范规定的抬梁式木构架和穿斗式木构架的局部倾斜残损点比试验结果小,规范值偏于安全。规范中规定的抬梁式木构架梁柱榫卯连接残损点略小于试验结果,规范值偏于安全;而规范中规定的穿斗式木构架梁柱榫卯连接残损点对于燕尾榫穿斗木构而言是安全的,但对于透榫穿斗木构而言,则是不安全的。     

Evaluating Intensity in the Processing of Guanaco (Lama Guanicoe) at the Lower Basin of the Colorado River (Argentina): Fragmentation Levels and Fracture Patterns Analysis

This article explores the levels of fragmentation and fracture patterns in archaeofaunal assemblages from the lower basin of the Colorado River (Argentina) following Outram's methodology. Remains of ungulates (guanaco) have suffered, in these assemblages, a high degree of fragmentation probably caused during the processing of the carcasses. The presence of helical debris and shaft fragments indicates that fragmentation would respond to processing tasks for the consumption of marrow and possibly bone grease. The results of the application of this methodology that were obtained from the analysis of three late Holocene sites (La Primavera, Loma Ruiz 1 and El Tigre) are presented. These results provide new evidence not only for patterns of marrow and bone grease consumption but also for dealing with the subsistence model proposed for the study area. In this sense, the intensification processes already proposed during the final late Holocene (1000–250 bp ) are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Walking a Fine Scientific Line: The Extraordinary Deeds of Dutch Neuroscientist C. U. Ariëns Kappers Before and During World War II

Dutch neuroscientist Cornelius Ubbo Ariëns Kappers is famous for pioneering neuroembryological work and for establishing the Amsterdam Central Institute for Brain Research. Less well known is his anthropological work, which ultimately played a role in saving Dutch Jews from deportation to their deaths during the Holocaust. Ariëns Kappers extensively campaigned against anti-Semitism and Nazi persecution during the 1930s. During World War II, he utilized his credentials to help create anthropological reports “proving” full-Jews were “actually” partial- or non-Jews to evade Nazi criteria, and at least 300 Jews were thus saved by Ariëns Kappers and colleagues. His earlier work demonstrating differences between Ashkenazic and Sephardic Jewish skull indices became the focus of an attempt to save hundreds of Dutch Portuguese Jews collectively from deportation. Ariëns Kappers and colleagues brilliantly understood how anthropology and neuroscience could be utilized to make a difference and to save lives during a tragic era.     

Bone frequencies: differential transport, in situ destruction,and the MGUI

Human transport of bones with high food values, and destruction of bones with low density values are the traditionally invoked explanations of the frequencies of bones in archeological contexts. The manner in which these two explanations have been used suggests archaeologists assume the explanations to be independent of one another. The transport explanation is operationalized as the modified general utility index (MGUI) of Binford, and the destruction explanation is operationalized with measures of bone density. Statistical correlation of the MGUI with bone density, while weak, indicates that many high utility bones have low density values while many low utility bones have high density values. Because low density bones tend to be destroyed more readily than high density bones, inferences of human utility strategies derived from bone frequencies and based on the MGUI may be inaccurate. The utility strategies suggested by three archaeofaunas are compared to bone density, and two of these faunas are shown to potentially be the result of differential destruction and not human transport as measured by the MGUI.

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。
