摘要：
During times of public crises, governments must act swiftly to communicate crisis information effectively and efficiently to members of the public; failure to do so will inevitably lead citizens to become fearful, uncertain and anxious in the prevailing conditions. This pioneering study systematically investigates how Chinese central government agencies used social media to promote citizen engagement during the COVID-19 crisis. Using data scraped from ‘Healthy China’, an official Sina Weibo account of the National Health Commission of China, we examine how citizen engagement relates to a series of theoretically relevant factors, including media richness, dialogic loop, content type and emotional valence. Results show that media richness negatively predicts citizen engagement through government social media, but dialogic loop facilitates engagement. Information relating to the latest news about the crisis and the government's handling of the event positively affects citizen engagement through government social media. Importantly, all relationships were contingent upon the emotional valence of each Weibo post. © 2020 Elsevier Ltd

摘要：
In recent years, the rise and development of massive open online courses (MOOCs) have promoted the boom of online education and also promoted the research on learning analysis and mining based on big data of education. However, while offering a large number of high quality courses, there is also a phenomenon that the overall learning effect is not ideal. How to make effective use of MOOCs for teaching activities poses urgent practical requirements for educators and researchers. MOOCs store massive learners’ learning behavior data, and mining these data is of great significance to learners’ learning effects. Due to the deviation caused by the correlation between many behavior indexes, the paper analyze the nine measurable performance indexes by principal component analysis (PCA), and get three principal components factors in order to reduce the computational dimension and increase the comprehensibility, and then obtain a model of learning effect prediction, namely the PCA prediction model (PCA_PM). Logistic regression algorithm has a good fitting effect on behavioral indexes. Therefore, the paper use the logistic regression method to construct another model of learning effect prediction, namely the principal component logistic regression prediction model (PCL_PM), and predictive effects of two models were compared and analyzed. The results show that it is an effective way to help learners to improve the passing rate of the course by establishing the predictive models. The prediction accuracy of both PCA_PM and PCL_PM is high, but overall, the prediction effect of PCA_PM is better. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

摘要：
当前,加强科技创新已经成为世界各国的重大发展战略,技术创新联盟建设也逐渐成为科技创新趋势,而技术创新具有研发周期长、投入集中、过程复杂等特点,使得构建创新主体间的深层次合作很有必要.采用扎根理论对技术创新联盟建设影响因素进行挖掘,提炼相应范畴,进而构建技术创新联盟的"动机—过程—行为"影响因素及作用路径模型.结果表明,联盟建设影响因素中,资源投入是开展创新合作的重要前提条件,协作动机是促进技术创新联盟构建的内在驱动,组织环境是实施创新合作的基础性条件,技术创新协同过程则是联盟运行的重要支撑条件.在联盟构建过程中,协同过程起部分中介桥梁作用,资源投入因素与组织环境因素起调节作用.

摘要：
SCSR项目既要保证企业获得显著的经济效益,同时也要促进社会福利增长,因此,如何来推动SCSR项目实施将是企业乃至社会面临的重要问题。本文以我国滴滴专车等专车服务项目为研究对象,采用验证性因子方法进行分析,发现目标导向、市场反应、经济效益和声誉机制等战略特质是促发并维持企业持续推进SCSR项目运作的主要驱动因素。此外,对于企业经营者来说,其对于SCSR项目战略特质的关注程度依次是经济效益、目标导向、声誉机制和市场反应。而关注社会福利的利益相关者,其对于SCSR项目战略特质的重视程度则依次是市场反应、经济效益、声誉机制和目标导向。本文的研究结果对于我国企业如何更好地实施SCSR项目提供了有益的启发。

摘要：
This paper primarily focuses on two questions: (1) "How is a sustainable entrepreneurship team (SET) formed?"; and (2) "What factors contribute to effective SET?". Based on the model of Baron and Henry (2011), we adopt a process view of SET development and propose a conceptual model of a SET work that includes four key elements: (1) Sustainable entrepreneurial motivation; (2) sustainable entrepreneurial opportunity recognition; (3) knowledge resources acquirement; and (4) sustainable entrepreneurial outcome. Furthermore, based on complex systems theory, we elaborate on how individual entrepreneurs form a SET. We also develop a SET scale and provide some initial empirical support for our conceptual model. Finally, based on our qualitative and quantitative results, we offer suggestions for Research Question 2. © 2018 by the authors.

高校教师;招聘;文献综述
摘要：
近五年来,我国高校教师招聘研究又取得了一定的成绩,同时也存在着一些问题。结合近五年文献,笔者从高校教师招聘相关概念的解释、招聘现状存在的问题、招聘发展相关对策、可采用的方法或技术、流程、招聘过程的模型化、国外比较、实证研究等八个方面进行了简单的总结。并结合这些研究成绩,认为过去的研究还存在三个问题:对高校教师招聘的现状与对策研究略显笼统;高校教师招聘的方法或技术研究不多;有关高校教师招聘的跨学科研究、实证研究与定量研究还比较少。
