综合性大学在校生移动阅读行为特征研究——基于用户体验的视角

采用用户体验、追踪访谈等实证研究方法,以武汉大学移动图书馆为例,从阅读时间、获取方式、阅读内容、阅读便利4个维度研究发现用户移动阅读认知和体验的行为特点：实验前对图书馆移动阅读服务了解少;实验者随时随地进行碎片化阅读,但受WiFi热点分布影响;对休闲娱乐类资源粘性强,对学术性内容阅读较少。基于此,为综合性高校图书馆移动阅读服务设计优化提出建议。     

本体与关联数据驱动的图书馆信息资源语义整合方法及其测评

探索语义网技术在图书馆信息资源整合中的应用。 首先,提出一个本体与关联数据驱动的资源语义整合框架, 实现：①图书馆中不同格式、不同类型文献资源的整合;②不同数据集合中信息资源的语义整合;③图书馆馆藏资源与外界相关资源的链接与集成, 从而构成一个可无限延伸与扩展的开放的资源整合体系。其次,构建一个资源整合演示系统。 最后,将该系统与使用传统资源整合方式的CALIS OPAC系统和CNKI进行实验对比。     

论应用文写作教学改革需要“手捧空花盆”

当下大量探讨《应用文写作》课如何进行教学改革的论文都循着主流意识将情境模拟、项目驱动和开展研究性学习等方法引进应用文写作教学过程。本文从宏观的角度在改革方向上充分肯定以上系列方法,同时在微观上对以上措施的可操作性提出了质疑,对一味强调这些方法而忽略动笔练习这一重要环节提出了质疑,并指出应遵重写作课的自身特点,最终必须落实到多写多练上,才能正真提高写作水平。     

Automated Scoring of Constructed‐Response Science Items: Prospects and Obstacles

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring.     

A Vocabulary Learning Tool for L2 Undergraduates Reading Science and Technology Textbooks

Students of English as a second language who major in science and technology use English-language textbooks to ensure that they can read English materials upon graduation. Research indicates that teachers spend little time helping these students on the linguistic complexity of such textbooks. Vocabulary, grammar, and article structure are elements of this complexity, but to many students, these elements can be akin to locked doors. This study presents MyVLS-Reader, which focuses on unlocking the first of these doors—vocabulary—while assisting in reading. With explicit vocabulary learning, students learn and memorize individual vocabulary, but the context is lost if the depth of learning discards context. In implicit vocabulary learning, students acquire vocabulary through repeated exposure to contexts, but repeated encounters with new words are required. Few e-learning systems combine both vocabulary-learning approaches. MyVLS-Reader achieves such synergy by (1) using a keyword setting to provide context-matched vocabulary explanation while reading and (2) embedding multiple learning choices, such as keyword setting, the review and memorization of explicit vocabulary, and the option to ask instructors. This study includes two rounds of evaluations: (1) an evaluation of the learning achievements of control and treatment groups and (2) a quantitative and qualitative investigation of perceptions regarding the use of MyVLS-Reader. The evaluation results indicate that the treatment group developed a better vocabulary than the control group in significantly less time. The use of MyVLS-Reader also slightly improved higher-order thinking skills. This result suggests that MyVLS-Reader can effective assist students in building their vocabulary while reading.

Depressed skull fractures: a pattern of abusive head injury in three older children

OBJECTIVE: To describe a pattern of abusive head injury in a series of children older than 4 years of age. METHODS: A hospital chart review of abused children with skull fractures from 1999 to 2001 was carried out. The clinical features, social background, and subsequent outcome and management are described. RESULTS: An 11-year-old girl and a pair of brothers of ages 7 and 9 were identified. The girl was attacked with a hammer during sleep by her stepmother, who committed suicide shortly afterwards. After craniotomy and intensive care, the child survived her multiple depressed fractures, intracranial bleeding, and brain contusion. Two brothers from a second family were attacked from behind with a hammer by their biological father, who was subsequently found to have undiagnosed schizophrenia. A depressed occipital fracture, without intracranial injury, was found in each child. The elder brother also had metacarpal fractures. Both children recovered without surgical intervention. CONCLUSION: A pattern of abusive head injury was described in older children with depressed skull fractures from blunt injury. The abusing parents were seriously mentally disturbed, and the abusive acts closely resembled child homicide.     

四种英国产香烟烟气中自由基的ESR分析研究

研究了用电子自旋顺磁共振(ESR)法对香烟烟气中的自由基进行分析的样品处理方法及ESR检测方法.对四种英国产香烟样品中的粒相及气相自由基进行了分析检测并对检测结果进行了讨论.结论:大多数英国产的检测样品香烟中,含有1.5～3倍于国产对照香烟样品的气相自由基;而国产对照样品香烟的粒相自由基的含量水平则处于较高水平.实验结果还显示:同品牌的Sobranie香烟中,不同型号样品中粒相自由基含量与焦油含量具有负相关性,但不同品牌则不同;对于检测样品而言,气相自由基的含量与焦油含量有正相关性.
