南非民主进程的顿挫与延续——略论博塔的改革总战略

博塔任南非政府首脑期间,面对索韦托暴动引起的政治、经济与社会动荡和国内外的新形势,提出和推行改革总战略：对不适应南非现代化建设和政治稳定的现存制度进行改革;坚决镇压反抗白人统治、破坏社会秩序的行为;全力营造一个有利于改革总战略的国际环境。其目的是维护白人统治和种族隔离制度。他的改革在沃斯特的种族政策调整与德克勒克的民主改革之间架起了一座桥梁,起到了承前启后的作用,将南非的改革进程带入一个新阶段,一定程度上改善了黑人的处境。但博塔的镇压造成国内局势紧张并迅速恶化,以至于到了几乎失控的程度,改革进程陷入停顿。

宝鸡建河墓地出土战国时期秦人骨的稳定同位素分析

<正>为配合陇海铁路宝兰复线陕西宝鸡段工程,2001年陕西省考古研究院先后两次发掘了宝鸡建河墓地,取得了重要收获。其中秦墓的发掘,是目前为止在陕西境内最西端、甘肃境内最东端的渭河北岸有关秦人踪迹的重要发现,为今后寻找秦人自西向东逐渐迁徙的足迹,乃至对秦文化的研究提供了可靠翔实的第一手科学资料。     

Assessing a Computer-aided Instructional Strategy in a World Geography Course

An experiment was conducted to compare student achievement under two differing instructional strategies: a small-group and computer-aided strategy versus lecture instruction. Evaluation was extended in several ways beyond comparison of overall student scores. Results show significant improvements in student achievement produced by the computer-aided strategy with reference to gender, ethnicity and levels of cognitive learning. The study concludes that experimental evaluations of CAI serve best as formative tools to match instructional strategies to specific types of content material and different types of students, and that instructional media are best evaluated along with the instructional method in which they are embedded.     

Teaching Postgraduate Development Studies: Possibilities within geography

This article outlines theoretical insights generated at the crossroads of geography and development studies, and elaborates their implications for postgraduate education. Reflecting on curriculum design and teaching experiences at one university (the University of Colorado, Boulder), the analysis focuses on the strengths of geography as a disciplinary home for postgraduate training in development studies. To this end, and based on faculty and student projects, it examines the relevance of geographic debates around space, place and scale for understanding specific development questions. While most postgraduate education in development geography already takes account of these themes, this article aims to make explicit the intellectual rationale behind such a focus, and to provide specific substantive strategies relevant to putting geography at the centre of postgraduate development studies education.     

Design Methodology for Seismic Upgrading of Substandard Reinforced Concrete Structures

This article presents a design methodology for seismic upgrading of existing reinforced concrete (RC) buildings. The methodology is based on the modification of the deflected shape of the structure so as to achieve a near-uniform distribution of interstorey drift along the building height, thereby eliminating damage localization. Yield Point Spectra are utilized for the definition of demand and a direct displacement-based design approach is implemented. The fundamental steps of the method are described in detail, including a systematic evaluation of assumptions and limitations. A full-scale tested structure is used as a case study for assessment and verification of the proposed methodology. Alternative retrofit scenarios are set according to target response and performance levels. The role of the target deflected response shape and its influence on the outcome of the retrofit strategy is investigated. The viability of the alternative retrofit scenarios is studied for different ground motions including near-fault earthquake records.     

俄罗斯的亚太战略与政策探析

俄罗斯作为苏联解体后的当然继承国,成为当今世界政治经济格局多极化发展趋势中重要的一极。目前俄罗斯承袭了苏联后期的亚太战略,并在某种程度上使其有所发展。本文在分析苏联后期实施亚太战略与政策的基础上,着重探讨了俄罗斯目前实施亚太政治经济战略的新东方政策与措施,并对其远东同亚太各国的经济联系的近期态势进行了实证分析;论述了中俄关系对实施其亚太战略的重要性;指出中俄建立面向21世纪的战略协作伙伴关系完全符合两国各自的地缘经济利益。
