基于语料库的外宣新闻话语效度研究———以People’s Daily Online体裁分析为例

语料库量化分析发现，People’s Daily Online外宣新闻体裁具有强历时稳定性，具体表现为标题结构模式化，信息来源机构身份强化，事件描述宏观化、数据化，事件评论主观化等特点，倾向于构建强势传者，而受众则相对弱势。这种关系造成两种效应：一是在资源高度集中的信息传播中，双方关系虽不平等，但仍处于平衡状态，传播效度较强。但外宣受众参与不足会造成其对信息的相关性感受减弱，对此，可通过增加阅读引导性元素、事件描述的个体性事例、事件评论的社会性引语等策略提升传播效度。二是在资源开放程度较高的信息传播中，双方关系既不平等，也不平衡，传播效度较弱。对此，需通过弱化传者的机构身份、为受众提供发声和交流途径等策略满足受众对平等关系的诉求。     

论在线消费者信息的法律保护

网络环境中,消费者信息的搜集和利用已经逐渐成为商家经营的基本手段,而在这一过程中反映出的消费者信息被侵害的案例已屡见不鲜。从在线消费者信息被侵害的案例说开去,通过分析在线消费者信息被利用的主要形式,从法律视角探析在线消费者信息享有者和利用者的权利义务关系,从而在分析我国目前立法现状的基础上提出完善相关法律的思考和构想。     

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.     

Monitoring correlation change in a sequence of random variables

We propose a monitoring procedure to test for the constancy of the correlation coefficient of a sequence of random variables. The idea of the method is that a historical sample is available and the goal is to monitor for changes in the correlation as new data become available. We introduce a detector which is based on the first hitting time of a CUSUM-type statistic over a suitably constructed threshold function. We derive the asymptotic distribution of the detector and show that the procedure detects a change with probability approaching unity as the length of the historical period increases. The method is illustrated by Monte Carlo experiments and the analysis of a real application with the log-returns of the Standard & Poor's 500 (S&P 500) and IBM stock assets.     

情绪与在线学习

传统上,情感和认知被认为是极端对立的,而且这一观点在学习理论当中有所体现。之所以有这样的认识是因为缺乏对情感的正确理解。事实上,情绪与认知有关,情绪与智力有关,情绪与学习有关。这些观点在网上学习的实践中逐渐呈现出新的活力。本文在调查访谈几十位不同层次的在线学习大学生之后,着重探讨有关在线学习的主要情绪以及这些情绪对网络教与学过程的影响。     

‘You are a parasite on the productive classes’: online disablist hate speech in austere times

In response to a climate of austerity, disability has been keyed to a meta-narrative that has a political purpose, to justify extensive welfare cuts by positioning disability as a drain on so-called ‘hard-working taxpayers’. This paper explores how this meta-narrative is articulated on the online bulletin board, Reddit, to show how disablist hate speech may emerge as an attempt to secure one’s sense of self during austere times. A critical discourse analysis (CDA) is employed to reveal these instances and highlights the normalisation of disablist hate speech within the wider context of welfare dependency. Based on these findings, this paper makes recommendations for future research and makes a call for policy change.
