Setting the Students’ Bearings and Balance in Appraisal

The author, a professor at the University of Toronto, touches briefly on the extensive and rich archival literature that supports the teaching of macroappraisal, but notes that this is not the only educational material she offers her students when teaching appraisal theory. She discusses the usefulness to archivists of literature from the fields of ethnography, organizational knowing, records in history, personal documentary behaviour, memory, and communications, noting that the use of texts from these fields can encourage students to reflect on their own presumptions and to develop a taste for the wide reading and research that must support appraisal.     

以现代远程教育为核心构建多种教育形式的立交桥

21世纪是知识经济的社会,是信息的社会,同时也是人人终生学习的社会,在这样的社会里,只有以现代远程教育为核心,来改造其它形式的教育,才能构筑起多种教育形式相互沟通的立交桥,从而为人人终身学习创造良好的环境服务。     

唐浞的诗歌意象理论

意象历来是诗学研究中的重要课题。在20世纪40年代，九叶诗派诗人、诗学家唐浞通过对诗歌历史与现状的考察，对意象及其特征进行了自己的独特描述，认为意象就是诗歌本身而不只是传达手段，意象是灵魂与意志的凝合，是潜意识与意识之间的桥梁，并认为凝定的“姿”是诗歌意象的形态特征。

Modelling of URM Walls Retrofitted with Cable：A Comparison Between a Basic Mechanical Model and Distinct Element Method

The Australian love of ＂heritage＂ buildings （most of them are unreinforced masonry （URM） ） means that greater attention is required to secure their performance under seismic or impact loading in the future. A research project has been carried out to develop a new, economic and high strength retrofitting technique for masonry structures. A series of experimental testing on URM walls retrofitted with an innovative technique by cable system have been conducted. In this paper, an analytical model which is based on distinct element method（DEM） is developed to simulate the behaviour of retrofitted walls, in DEM, a solid is represented as an assembly of discrete blocks. Joints are modelled as interface between distinct bodies. It is a dynamic process and specially designed to model the behaviour of discontinuities. In order to assist the practising engineers to design this new retrofitted wall system, a simple mechanical model was also developed to predict the strength of the retrofitted walls. The results obtained from this simple mechanical model are compared with those from both experiments and distinct element model.
