    In this paper, the authors crawl unexpected event corpus from Sina Weibo and Twitter. Topic model are used to obtain candidate topics. According to the results of topics clustering, the authors will get appropriate topic number. Then, the authors calculate similarities between two neighbor topics according to time.Finally,the authors present comparative analysis of topic evolution between Chinese and English. The experimentaexperi results show that: comparing with corpora of Twitter, topic number is larger and topics are more extensive on corpora from Sina Weibo; there are more arguments in China to the outbreak of H7N9 and the topic content in Chinese and English is different;additionally, visualization of topic evolution on these two platforms can describe the emerging of new topics, the ending of old topics and the change of topic content over time.

    Based on the interview of researchers, this paper makes a qualitative research on the motivations and barriers of researchers participating in the self-archiving movement. The results show that the intention to support open access of research output and promotion of research performance are the main motivations of resource archiving, while the barriers include the lack of understanding and concerns about risks. The motivations of resource usage include the self-archiving resources are the useful supplement of existing scholar communica tion system, free access and convenient retrieval. In contrast, the concerns about the quality of resources and the lack of influential self-archiving platform are the main barriers of resource usage. In the end, this paper proposes some suggestions, such as strengthening publicity and promotion, and enhancing quality control.

    By constructing the model of service recovery, public sentiment and the willingness of word-ofmouth communication, the influence of different service recovery methods on public word of mouth is studied. The analysis shows that the effect of proactive and reactive recovery by the local government on public emotion and word-of-mouth behavioral intention diversifies significantly in the four types of scenarios of service failure and recovery. Compared with passive remedy, the active recovery by the local government has great influence on the positive public emotion and word-of-mouth intention, but smaller impact on the negative sentiments. At the same time, word-of-mouth behavioral intention is positively correlated with public positive sentiment and negatively correlated with negative public emotion. In addition, the remedial effect of the outcome failure is remarkably higher than that of the process fault.
