秦汉政治史观的演变历程

秦汉时期共有三种主要的政治史观：以五行相胜原则运转的五德终始说、以五行相生原则运转的汉为尧后说,以及董仲舒所创三统说。秦到汉武帝时,五行相胜的五德终始说占政治史观的主流,汉昭帝以后则被五行相生的政治史观代替,董仲舒创立的三统说在汉武帝时形成,此后便和五行相生政治史观平行发展。这三种政治史观都与阴阳五行有密切关联,并对秦汉乃至以后两千余年封建社会产生深远影响。

From Hawaii to Glasgow: The International Network for Learning and Teaching Geography in Higher Education (INLT) Five Years On

This paper examines and reflects on the activities of the International Network for Learning and Teaching Geography in Higher Education (INLT) from its founding at the Association of American Geographers' Annual Conference in Hawaii in 1999 to the post-International Geographical Congress workshop in Glasgow five years later. It provides a context and introduction to the following six papers, which resulted from the Glasgow workshop. It is suggested that, despite some of the proposals in Hawaii proving over-ambitious, several other projects have emerged and the INLT continues largely to meet the goals and purposes set out in 1999. Although the desire of the INLT to move beyond its Anglo-American and Australasian origins largely remains a challenge to be met, the INLT has established itself as a valuable forum for the geography higher education community to identify and reflect on similarities and differences in national practices, to engage in debate virtually and face-to-face on issues concerned with learning and teaching, and to bring geographers from different countries to work together on educational projects.     

Humanising the Technology Landscape through a Collaborative Pedagogy

A major shift in educational paradigms from a competitive model to a more collaborative model is now under way in higher education. Using collaborative theories espoused by Freire, Bruffee and other scholars working outside the discipline of geography, this paper presents an argument for integrating their collaborative approach into distance education courses at the postgraduate level. The Step Up to Geography Through Distance Learning project is used to provide one innovative model that integrates not only the collaborative method of instruction, but also the use of a multi-layered system of instructional technologies including use of desktop videoconferencing and the Internet.     

初中数学活动课操作策略初探

数学活动课可安排学生进行探索性的活动,通过一些具体的操作,亲自实践,然后由学生对问题进行思考,得出数学结论,培养学生解决问题的能力和探索问题的精神。学习的过程,不仅是一个学生主动参与的过程,更是一个学生创造的过程。学生在这个探索空间里,不仅是一个发现者、探索者,更是一个创造者。     

When Policy Goes Wrong: The Problem of Transmitted Risk

Why do policies fail? There are many answers to this question, and many ways of answering it. In this paper, we use the tools of policy framing and systems thinking to investigate two recent Australian examples of public policy failure, each involving a different policy milieu and time-span. We show that, in both these cases, unintended consequences arose because governments lost control of the implementation process while remaining politically accountable for the outcomes. We develop the concept of transmitted risk to show how this occurred. We argue that governments expose themselves to this kind of risk when they make policy decisions involving a combination of excessive incentives and poorly controlled third parties.     

SEISMIC RESPONSE CONTROL OF CABLE-STAYED BRIDGE USING DIFFERENT CONTROL STRATEGIES

The goal of this research is to study the effect of cable vibration through a number of control cases of a cable-stayed bridge. In order to consider the complicated dynamic behaviour of the full-scale bridge, a three-dimensional numerical model of the MATLAB-based analysis tool has been developed by the complete simulation of the Gi-Lu bridge. The dynamic characteristics of cables in the cable-stayed bridge are verified between the field experiment and the result from numerical simulation using geometrically nonlinear beam elements in MATLAB program. Three types of control devices are selected to reduce the response of the bridge deck which includes: actuators, viscous-elastic dampers with large capacity, and base isolations. Moreover, two types of control devices, MR dampers and viscous dampers, are installed either between the deck and cables and/or between two neighbouring cables for controlling the cable vibration. A modified bi-viscous model combined with convergent rules is used to describe the behaviour of MR dampers. Finally, through evaluation criteria the control effectiveness on the cable-stayed bridge using different control strategies is examined.
