唐代贾耽的地理(地图)著述及其地图学成绩再评价

对唐代贾耽的地理(地图)著述的名目进行辨析,分析了"关中陇右及山南九州等图"、《九州图》、《海内华夷图》之间的关系,以及别录与通录的区别。指出《九州图》、《海内华夷图》是贾耽国图撰修总体事业在不同历史阶段的总称。并从地图学传统、方志学传统入手,探讨了贾耽地理(地图)著述的性质,对其中的地图学成绩进行了重新评价,进而从"近意就实,依稀像真"分析了贾耽地图学的滞后性,指出"古墨今朱"应只是文字注记的区别,并非通过图形绘制表达古今地理要素的差异,由此审视了中国古代地图史上图形绘制与文字注记的关系。     

Voting Technology,Political Institutions,Legal Institutions and Civil Society: A Study of the Hypothesis of Cultural Lag in Reverse

The 2000 Presidential election was plagued by butterfly ballots and ‘pregnant chads’. Electronic voting systems, lacking verifiable paper trails that are subject to possible fraud, promise to wreak havoc with the 2004 Presidential election. There is a great diversity of systems of voting technology in the 50 states: from paper ballots, lever‐operated machines and punch cards to optical scanners and electronic systems. Associated with each technology is an estimated error rate. The underlying theory of this paper was set forth by William F. Ogburn in his famous book entitled Social Change, published in 1922. Dividing culture into material and non‐material elements, Ogburn argued that non‐material elements lag behind material elements. His explanation for this lag is that technology, which underlies material culture, changes at a faster rate than elements of non‐material culture. Obgurn did not contemplate the possibility of a reverse lag, viz., technology lagging behind non‐material culture. In analyzing the anomalous relationships between voting technology, political institutions and legal institutions, a striking instance of a ‘reverse cultural lag’ is discerned. To eliminate the phenomenon of the reverse cultural lag, there is a need for a federally‐funded program of a uniform, state‐of‐the‐art voting technology, plus an amended Help America Vote Act, to implement the innovations in the 3,114 counties. The complex problems reviewed in this paper point to a vexing question: how do we educate an electorate in a democratic society—such as the United States in the twenty‐first century—to be responsible for ensuring that periodically‐elected representatives implement the will of the people?     

Can Lost Maps Speak? Toward a Cultural History of Map Reading in Medieval China

Despite the fact that virtually no Chinese maps have survived from the first millennium, it is nonetheless possible to reconstruct a rich context associated with their production, use and perception from a variety of written sources. Three cases from the Tang dynasty (618–907 ce) are presented in this article in which the characteristics of the missing maps emerge through their associated texts, which have outlasted them. These examples include two documents that once accompanied maps presented to the emperor and an anecdote that refers to a map of the remote southern frontier. They demonstrate that the maps were designed not only to encapsulate imperial territory but also to serve as guideposts for aspirational travel. They were also perceived by their users as invitations to experiences both desirable and undesirable.     

An analytically solvable core-periphery model

We develop an analytically solvable version of the central modelof ‘new economic geography’, the so called core-peripherymodel by Krugman. While the modified model reproduces all theappealing features of the original one, it also allows us toobtain additional analytical results that are out of reach inKrugman's set-up. First, we are able to assess the exact numberof equilibria and their global stability properties. Second,we are able to investigate the implications of exogenous asymmetriesbetween countries. This is achieved by introducing heterogeneitybetween high-skill mobile and low-skill immobile workers, whichmay also be an empirically attractive property.     

“生态环境”用语产生的特殊时代背景

本文随着地理学家黄秉维院士的回顾,对1980-1982年五届全国人大宪法修改过程中,将草案中的“生态平衡”改为“生态环境”一词、并写入宪法的过程,再现出来予以分析讨论,认为“生态环境”概念提出的背景是全球和中国谋求环境保护事业发展的时代潮流,侧重的是人民生存于其中的自然环境的生态质量,具有积极的社会昭示作用和教育意义,不宜仅从学理上认为“生态环境”的提法有错,因为真实的世界往往比学者头脑中的理论思维更精彩。学术界于2005年5月展开的对“生态环境”、“生态环境建设”概念的研讨,贡献了许多真知灼见,然而,从“生态环境”一词在人大常委会产生过程的基本事实判断,它属于具有相对独立性的政府用语(法定名词),而非严格的科技名词,主要使用于国家行政管理层面,而学术研究中则主要是尊重学者自己的理解和创作。至于如何健全政府用语、消除政府不当用语在国家社会生活中可能带来的负面影响,正是学术界应该积极探讨的问题。     

辨"真二千石"为"二千石"之别称

汉代史料有“真二千石”之名目,注释家如淳、颜师古、司马贞等及若干当代学者皆以为汉官秩有“真二千石”之秩级。杜佑则谓二千石“亦曰真二千石”。今考辨汉代并无官员之秩级为真二千石,真二千石为二千石之别名。     

宁波保国寺大殿风振性能研究

为了更科学地保护我国传统木构建筑,需要研究我国江南地区传统木构建筑的风振性能,为此,以江南地区最古老、保存最完整的佛教木构建筑——保国寺大殿的主殿为例进行风振性能研究。首先基于三维激光扫描获得的真实可靠的保国寺大殿的几何信息,采用SAP2000有限元软件建立主殿的有限元模型,并进行动力特性分析。再利用MATLAB软件编写脉动风速时程,并将风压作用于有限元模型上分析,得到主殿的风振响应。得到结构模态、位移时程曲线、位移谱曲线、加速度响应,并对时程位移风振系数和规范风振系数进行对比。结构的振动响应主要由前三阶振型控制,在强风荷载作用下,最容易出现的变形就是南北向振动、东西向振动和扭转振动;各个典型节点的最大位移均在侧向位移容许值内;迎风面阑额中心位移最大、屋面上半部次之、屋面下半部及檐柱柱头最小;主殿相连的两个部分的加速度相差较多,屋面和屋身的连接节点应成为日后保国寺大殿的保护重点;时程风振系数变化与规范风振系数的变化规律不同是因为结构横向刚度分布不均匀;时程风振系数是规范风振系数的1.2~1.4倍,这是由于按照规范计算风振系数的过程中只考虑了第一阶振型的影响而忽略其他所有振型的结果;规范风振系数的计算只适用于形状、质量沿高度不变的高耸结构,不适用于类似本研究中的低矮木构传统房屋结构。
