Negativity of news coverage is widely documented. We examined whether the news media’s preference for reporting negative events was salient in news coverage of the outbreak of Middle East respiratory syndrome (MERS) in South Korea, which was characterized by intensification or mitigation of viral spread. The daily number of news stories on the outbreak was compared with several viral spread indices to determine if the media responded to negative changes more than positive changes. At the aggregate level, the amount of MERS news coverage was associated with positive changes. When the number of newly confirmed patients decreased, the MERS news increased. However, a separate investigation of breakout and abatement stages showed that the media covered more negative changes during the breakout stage and shifted to more positive occurrences during abatement. These findings are discussed in light of the dynamics of journalistic attention to health crisis. 相似文献

Variable selection for semiparametric proportional hazards model under progressive Type-II censoring
Variable selection is an effective methodology for dealing with models with numerous covariates. We consider the methods of variable selection for semiparametric Cox proportional hazards model under the progressive Type-II censoring scheme. The Cox proportional hazards model is used to model the influence coefficients of the environmental covariates. By applying Breslow’s “least information” idea, we obtain a profile likelihood function to estimate the coefficients. Lasso-type penalized profile likelihood estimation as well as stepwise variable selection method are explored as means to find the important covariates. Numerical simulations are conducted and Veteran’s Administration Lung Cancer data are exploited to evaluate the performance of the proposed method. 相似文献

In this study we examine the moderating effect of competitive strategy (including differentiation and cost‐leadership strategies) on the relationship between exploration and firm performance. We find that the moderating effect of differentiation strategy is positive while that of cost‐leadership strategy is negative. And, these moderating effects are stronger in a highly competitive context. This study offers an explanation for previous mixed findings on the linkage of exploration to firm performance and enriches the discipline's knowledge regarding the performance implications of exploration. Moreover, we respond directly to the appeal in research on competitive strategy to clarify the role played by competitive strategy in profiting from exploration. 相似文献

Drawing upon findings from a national evaluation of student social workers' experiences of ‘non-traditional’ placements with a national charity, this article considers what such placements can contribute to the development of an individual and collective sense of professional identity for social work. This is explored against the background of current developments in social work education in England, including changes to the requirements for practice placements and the introduction of ‘fast-track’ routes to qualification, preparing students for social work in statutory children's services. The article suggests that with the establishment of The College of Social Work and the development of the Professional Capabilities Framework, relevant to all social workers throughout their careers, the profession has an opportunity to promote a concept of social work in England beyond that required by statutory sector employers; and that practice learning in non-statutory and non-traditional settings has an important role to play in this. 相似文献

The arrival of critical citizens: decline of political trust and shifting public priorities in China
Political trust has been in decline in China. In this article, we capture this decline as reflecting the modernization of Chinese political culture. While the government managed to deliver a sustained period of rapid economic growth, the public's trust in it is diminishing through two mechanisms. On the one hand, Chinese citizens are acquiring stronger liberal democratic values, which make citizens more critical toward government institutions. On the other hand, changing political culture is also shown in the citizens’ shifting of their priorities toward the expansion of freedom and empowerment of citizens. Decades of socioeconomic modernization, therefore, meant that the era of critical citizens has arrived in China. 相似文献

经济增长时期的国民幸福感——基于CGSS数据的追踪研究 总被引:1,自引:0,他引:1
为回应有关中国国民幸福感的争论,评估过去10年宏观经济和政策变化对普通人生活的影响,利用中国综合社会调查数据(CGSS),分析近10年国民幸福感变化趋势。研究基于5个时点、44166个样本,发现中国国民幸福感在过去10年内一直处于上升趋势,不同政治身份、户口类型、年龄、收入、婚姻状况、民族等群体的幸福感在过去10年都有不同程度的提高。经济增长可能是幸福感提升的动力;如果经济收缩,那么幸福感也可能随之下降。要确保经济社会协调发展,尚需对幸福感进行更多、更细致的追踪和研究。 相似文献

多维视角下的中国家庭婚姻研究结构、关系、家族和文化 总被引:1,自引:0,他引:1
20世纪80年代以来,社会形态、经济结构的巨大变化使原有的社会规范被打破,新的价值观念和价值判断出现,整个世界都在发生着巨变,家庭毫无例外地经受着前所未有的考验,出现了所谓的“家庭危机”。有的西方学者把它概括为六大危机,又称“六D危机”,即违背期望(Deviations from expectations)、丧失荣誉(Disgrace)、经济萧条(Depression)、家庭成员分离(Departure of family members)、离婚(Divorce)、死亡(Death)(张怀承,1993)。在这样的一个大背景下,家庭婚姻的研究面临着许多新的课题,研究的内容不断扩展,研究的手段不断更新,研究的问题也逐渐深化。本文梳理了近年来学者对社会变迁背景下家庭变化的多种现象描述和理论解释,试图对近年来有关家庭婚姻的研究进行一个综合。 相似文献
