《搜神记》形容词的兼类和活用现象考察

文章主要对《搜神记》中形容词兼类和活用进行了列举考察,分析认为,《搜神记》形容词兼类和活用的对象主要是动词和名词,对其他类的词没有兼类现象。同时,我们认为《搜神记》中形容词的兼类现象在使用上多于活用现象。     

Efficient online index maintenance for contiguous inverted lists

Search engines and other text retrieval systems use high-performance inverted indexes to provide efficient text query evaluation. Algorithms for fast query evaluation and index construction are well-known, but relatively little has been published concerning update. In this paper, we experimentally evaluate the two main alternative strategies for index maintenance in the presence of insertions, with the constraint that inverted lists remain contiguous on disk for fast query evaluation. The in-place and re-merge strategies are benchmarked against the baseline of a complete re-build. Our experiments with large volumes of web data show that re-merge is the fastest approach if large buffers are available, but that even a simple implementation of in-place update is suitable when the rate of insertion is low or memory buffer size is limited. We also show that with careful design of aspects of implementation such as free-space management, in-place update can be improved by around an order of magnitude over a naïve implementation.     

陶艺课堂中培养学生的创造思维能力

随着新课程的实施,陶艺教学活动在课堂中出现,在陶艺教学过程中,学生的十指不间断地作多种方式的运用和配合,从而使双手变得灵巧,这一切都有利于学生大脑使用程度和使用方式的开发和改善,使人变得有创造力。可以说陶艺课堂是发展学生创造思维能力的好场所,是进行审美教育、创新教育和动手能力的有效途径和方式,是素质教育非常有效的载体之一。     

具有约束的实验分组设计的禁忌搜索算法

实验分组设计是许多科学研究都要面临的问题,常常要求分组中的因子之间必须满足一定的约束关系,这样,该问题就转化为给定一组约束关系,要求设计出满足这组约束关系的实验分组。本文以心理学中的语言学习问题的实验研究为例,探讨了如何把这样一个具有约束的实验分组设计问题转化为最小化优化问题,然后使用禁忌搜索算法去解决它,仿真表明所采用的方法是有效的。     

Collaborative epistemic discourse in classroom information-seeking tasks

The authors discuss the relationship between information seeking and epistemic beliefs – beliefs about the source, structure, complexity and stability of knowledge – in the context of collaborative information-seeking discourses. They further suggest that both information seeking, and epistemic cognition research agendas, have suffered from a lack of attention to how information seeking as a collaborative activity is mediated by talk between partners – an area they seek to address in this article. A small-scale observational study using sociocultural discourse analysis was conducted with eight 11-year-old pupils who carried out search engine tasks in small groups. Qualitative and quantitative analysis were performed on their discussions using sociocultural discourse analytic techniques. Extracts of the dialogue are reported, informed by concordance analysis and quantitative coding of dialogue duration. The authors find that: (1) discourse which could be characterised as ‘epistemic’ is identifiable in student talk; (2) it is possible to identify talk which is more or less productive; and (3) epistemic talk is associated with positive learning outcomes.
