The Archival Bond

This paper presents the concept of archival bond as formulated by archival science and used in a research project carried out at the University of British Columbia, entitled The Preservation of Electronic Records. Being one of the essential components of the record, the concept of archival bond is discussed in the context of the traditional diplomatic and archival definitions of records, and its function in demonstrating the reliability and authenticity of records is shown. The most serious challenge with which we are confronted is to make explicit and preserve intact over the long term the archival bond between electronic and non electronic records belonging in the same aggregations.     

School context and instructional capacity: A comparative study of professional learning communities in rural and urban schools in China

This study examines the teaching gap between rural and urban schools in China from the perspective of teacher professional learning communities (PLCs). Drawing on in-depth interviews with 36 primary school teachers, the study finds striking disparities between rural and urban schools in the working of Teaching and Research Groups (TRGs). These disparities in TRGs result in divergent patterns of instructional capacity building in rural and urban schools. The evidence shows that teaching and teachers are strongly shaped by the school organizational context. It suggests that strengthening school-wide PLCs is an important way of narrowing the rural-urban teaching and learning gaps.     

“双‘三维一体’”协同教育观研究

"协同教育"是协同学理论在教育领域应用而形成的新的教育理论。"双‘三维一体’"协同教育是在整合"三维一体"协同教育优点,总结"三维一体"协同教育在实践过程中出现的不足和缺陷而形成的新的理论。"双‘三维一体’"协同教育强调纵向"三维一体"——学校、家庭、社会各系统教育力量的互相结合、协调统一,同时强调横向"三维一体"——哲学、科学、实践的结合、协调、同步,同时还强调纵向与横向"三维一体"的彼此融合、协调、协同发展。

功能文体学与大学英语教学

在大学英语教学当中,教师们往往会更多地关注词汇和语言点的教学。但是这种模式往往脱离了语境,不利于学生对于整个语篇的把握,不利于培养学生的综合语言运用能力。本文通过对《新编大学英语》第一册第四单元的课文"Fresh Start"的功能文体分析指出,功能文体分析可以更好地解释和解读课文,也有利于提高学生的语言理解能力和鉴赏能力。     

揣摩语境选取语义

英语词语的意义由其所处的语境来决定 ,尤其是不同的学科有其独特的意义。译者在翻译时须予以重视 ,认真揣摩原文的语境 ,正确选取语义。同时 ,译者对所译学科的术语有所掌握或了解无疑有助于译文的通畅达意。此外 ,译者不可忽视历史文化背景决定语义     

学术文献引文上下文自动识别研究

[目的/意义] 引文内容分析能够帮助揭示文献引用关系的深层语义内涵,而引文上下文识别作为引文内容分析的基础显得尤为重要。[方法/过程] 梳理已有引文上下文研究的现状,总结当前引文上下文识别的不足,在此基础上归纳引文上下文识别的5类特征,并采用文本分类和序列标注两种方法开展引文上下文自动识别实验。[结果/结论] 实验结果表明,本文提出的特征能够很好地提升引文上下文识别效果,且基于文本分类的SVM分类效果要优于基于序列标注的CRF。
