秦俑陶片的偏光显微分析研究

为了预防性保护和修复秦俑,必须掌握秦俑残片显微结构及其烧制环境、破损方式,从而为改善秦俑修复工艺、筛选修复材料提供基础,运用偏光显微镜对秦兵马俑残片中的一些矿物质(石英、长石、云母等)颗粒的分布形态和含量来分析陶土的成分结构、制作工艺、烧成气氛及原料来源等信息。结果表明,秦俑陶片主要成分为少量砂屑及大量粘土,而粘土为岩土矿风化的产物,秦俑残片裂痕较多的部位风化、酥粉痕迹明显。秦俑制作工艺以模为主,模、塑结合,并在粘土中添加了细砂,多于还原气氛中烧制而成。

How Should We Wage the War on Drugs? Determinants of Public Preferences for Drug Control Alternatives

When citizens are presented with alternative policy solutions to a given social problem, why do they choose to support one over another? In this article, the authors analyze a survey of residents of the five largest U.S. metropolitan areas to understand determinants of public support for spending on three major components of American drug control policy: law enforcement programs, rehabilitative services for addicts, and school‐based prevention programs. The authors estimate effects of self‐interest, political socialization, and policy attitudes on support for total drug control expenditures and on preferences for each drug control alternative versus the others. Effects of group self‐interest, societal interest, and political socialization change dramatically across dimensions of support. Policy attitudes are strong predictors of both types of support, whereas individual self‐interest measures are not associated with either dimension.     

Evaluating the geographic concentration of industries using distance-based methods

We propose new methods for evaluating the spatial distributionof firms. To assess whether firms are concentrated or dispersed,economists have tradi-tionally used indices that analyse theheterogeneity of a spatial structure at a single geographiclevel. We introduce distance-based methods, Besag's L function(derived from Ripley's K function) and Diggle and Chetwynd'sD function to describe simultaneously spatial distribution atdifferent geographical scales. Our empirical applications considerthe distribution of French manufacturing firms in the Parisarea and in France generally. For some geographic levels, resultsshow significant concentration or dispersion of firms accordingto their sector of activity.     

The Saxons within Carolingian Christendom: post-conquest identity in the translationes of Vitus,Pusinna and Liborius

The Franks incorporated Saxony into the Carolingian empire through a long, brutal struggle coupled with forced conversion. When Saxons themselves began to write a few decades afterwards, they had to make sense of this history and of their role and identity in their contemporary Carolingian world. In contrast to the portrayal of Saxons in writers such as Einhard and Rudolf, three ninth-century Saxon accounts of relic translations — those of Vitus, Pusinna and Liborius — reinterpreted history to claim a place for the Saxons as a distinct group equal to the Franks within the populus Christianus under the Carolingian monarchs. As a key part of their literary strategies, these authors attempted to salvage from the story of their defeat and forced Christianisation an account of God's sovereignty, native agency and virtue (especially fidelity) as a foundational element of Saxon identity. These texts prefigure the debates about post-conquest Saxon identity which would underlay the later and better-known Ottonian triumphal self-conceptions. Moreover, the concerns of these authors led them to remarkable hagiographical innovations in grappling with paganism, conversion, miracles, social class and faith.

成都市新都区新石器时代晚期土坑墓提取与保护

2008年1月,成都文物考古研究所与成都市新都区文物管理所在对一新石器时代晚期聚落遗址进行的考古发掘中,清理出土了二座竖穴土坑墓,其中M1墓葬人骨基本完整,具有较高的研究价值,但因年代久远和有害环境的影响,骨质已粉化,不便于直接提取人骨。为了有效地保护这一新石器时期人类骨骸,为后期的科学研究保存下这一珍贵的实物资料。决定采取套箱法对整座土坑墓进行提取的方式保护人骨,经过多方试验,确定采用A305黏结剂修复骨架裂纹,用GSA-102保护剂,B365作加固进行保护。经观察表明,本次土坑提取与保护取得了良好效果,并制定了一套科学的保护方案。该土坑墓的成功提取和科学保护,为今后在潮湿环境中的古遗址保护提供了可供借鉴的经验。
