基于在线评论的区域需求偏好识别方法

用户需求存在着区域差异，识别区域需求偏好是企业区域化经营策略的决策基础。为此，本文提出了一种基于在线评论的区域需求偏好识别框架。首先，从在线评论中提取产品特征，并判定产品特征的情感极性；然后，基于特征情感计算客户的产品满意度；最后，利用假设检验的方法识别特征情感极性和产品满意度的区域差异。为了验证框架的有效性，本文利用汽车之家网站上的汽车产品评论数据进行分析。实验结果表明，油耗、空间、外观和内饰等特征的情感极性以及产品满意度受区域因素的影响十分显著。研究结果建立起产品特征情感极性和产品满意度与区域特征的关联联系，为企业的区域化产品设计与营销策略提供理论支撑。     

Challenges in Multidisciplinary Systematic Reviewing: A Study on Social Exclusion and Mental Health Policy

In the clinical sciences, systematic reviews have proved useful in the aggregation of diverse sources of evidence. They identify, characterize and summate evidence, but these methodologies have not always proved suitable for the social sciences. We discuss some of the practical problems faced by researchers undertaking reviews of complex and cross‐disciplinary topics, using the example of mental health and social exclusion. The barriers to carrying out social science and cross‐disciplinary reviews are reported and some proposals for overcoming these barriers are made, not all of them tried and tested, and some of them controversial. Using a mapping approach, a wide‐ranging search of both clinical and social science databases was undertaken and a large volume of references was identified and characterized. Population sampling techniques were used to manage these references. The challenges encountered include: inconsistent definitions of social phenomena, differing use of key concepts across research fields and practical problems relating to database compatibility and computer processing power. The challenges and opportunities for social scientists or multidisciplinary research teams carrying out reviews are discussed. Literature mapping and systematic reviews are useful tools but methods need to be tailored to optimize their usefulness in the social sciences.     

Confidence regions for parameters in linear models with additional information

Using given significant additional information it is possible to improve different confidence regions for the regression parameters in a linear model. Thereby, the given informations may concern the expectation and (or) the variance of the observations, and an improvement is possible in the sense of the decrease of the confidence regions' size. In particular it is possible to improve the so called confidence ellipsoids which are often used to estimate the considered parameters.     

英汉语学术书评中的元话语比较研究

近午来对“元话语”的研究不断受到关注。相关的研究证明了元话语在众多体裁中的重要性——语篇、表明作者对命题的态度以及与读者互动交流。采用Hyland＆Tse（2004）的元话语理论框架，基于对语料库的分析，比较和探讨英、汉语学术书评中元话语使用的异同情况及相应的社会文化根源。

中小学校和中小学教师承担的侵权损害赔偿责任——我国未来侵权法应当规定的原则

中小学校、中小学教师应当就其过失行为引起的损害对遭受损害的中小学生承担侵权损害赔偿责任,即便导致中小学生遭受损害的侵权行为是由中小学生、中小学校教职员工以外的社会公众进入中小学校实施的,中小学校、中小学教师也应当对遭受损害的中小学生承担侵权损害赔偿责任,只要中小学校、中小学教师在保护其中小学生的人身安全方面存在过失;中小学校、中小学教师承担的此种侵权损害赔偿责任不得在中小学校、中小学教师同实施侵权行为的社会公众之间进行分配并因此让中小学校、中小学教师承担所谓的补充责任.     

城市岩溶区地铁隧道的溶洞超前探测及处治技术

以正在施工的大连地铁2号线（松江路站～东纬路站）暗挖区间工程为例，介绍了暗挖爆破法穿越富水岩溶区、溶洞发育区域时的施工工序流程和超前地质预报手段。利用地质补勘钻孔、超高密度电法跨孔电阻率CT探测、洞内超前探孔等技术手段详细探明溶洞发育位置、形态，通过洞内与地表相结合的处理方式消除或减小溶洞对暗挖施工的影响。超前地质预报手段与施工工序流程的成功应用，为类似环境下城市地铁施工提供参考及借鉴意义。     

An Annotated Bibliography

This annotated bibliography on undergraduate research presents seventeen publications from serials in the library literature covering 1980 to June 2006. These publications are significant contributions from prominent authors that converge at a growing body of library literature on undergraduate research. With a focus on research behaviors, the annotated bibliography has four dimensions: a theoretical framework, main findings of undergraduate research behaviors, relations between faculty and undergraduate research, and a flip side of undergraduate behaviors. Hopefully, this annotated bibliography will familiarize readers with attitudes towards and practices in undergraduate research and a continuation of the research in untouched aspects.
