Through a thematic content analysis of 118 journal articles from interdisciplinary fields, this study reviews the research trends of online crisis communication literature in a Chinese post-truth society, where objective facts play a diminishing role, and Chinese people are losing their trust, despite the best efforts of organizations to deal with fake news in crises. Results of this study disclose some unique crisis communication strategies (e.g., strategic distraction, rumor-rebuttal, fabrication, acting cute, and content censorship) in crises of China. Influential contextual factors such as the political system, cultural values, and media features are identified as well. Theoretical and practical implications of this study are discussed, and a greater picture of online crisis communication in contexts is posited for future research.  相似文献

In this paper, we consider the laws of large numbers for NSD random variables satisfying Pareto-type distributions with infinite means. Based on the Pareto-Zipf distributions, some weak laws of large numbers for weighted sums of NSD random variables are obtained. Meanwhile, we show that a weak law for Pareto-Zipf distributions cannot be extended to a strong law. Furthermore, based on the two tailed Pareto distribution, a strong law of large numbers for weighed NSD random variables is presented. Our results extend the corresponding earlier ones.  相似文献

Uniform designs are widely used in various scientific investigations and industrial applications. By considering all possible level permutation of the factors, a connection between average centered L2-discrepancy and generalized wordlength pattern for asymmetrical fractional factorial designs is derived. Moreover, we present new lower bounds to the average centered L2-discrepancy for symmetrical and asymmetrical U-type designs. For illustration of the theoretical results, the lower bounds for symmetrical and asymmetrical U-type designs are tabulated, and numerical results indicate that our lower bounds behave well and can be recommended for use in practice.  相似文献

基于信息不对称理论,本文以2013-2016年深交所重污染行业上市公司为研究样本,分析了机构投资者实地调研对企业环境治理的影响及其作用机制。研究发现,机构投资者实地调研对企业环境治理具有积极的推动作用;在环境信息披露较差以及本地子公司较多的企业中,机构投资者实地调研的环境治理作用更为明显。进一步考察实地调研对企业环境治理的影响路径发现,机构投资者实地调研推动了企业环境治理的资本市场监督和媒体监督。本文的研究验证了信息不对称理论在环境治理中的作用,拓宽了实地调研经济后果的研究领域,对于深入理解并推动我国企业环境治理具有重要的现实意义。  相似文献

We present APproximated Exhaustive Search (APES), which enables fast and approximated exhaustive variable selection in Generalised Linear Models (GLMs). While exhaustive variable selection remains as the gold standard in many model selection contexts, traditional exhaustive variable selection suffers from computational feasibility issues. More precisely, there is often a high cost associated with computing maximum likelihood estimates (MLE) for all subsets of GLMs. Efficient algorithms for exhaustive searches exist for linear models, most notably the leaps‐and‐bound algorithm and, more recently, the mixed integer optimisation (MIO) algorithm. The APES method learns from observational weights in a generalised linear regression super‐model and reformulates the GLM problem as a linear regression problem. In this way, APES can approximate a true exhaustive search in the original GLM space. Where exhaustive variable selection is not computationally feasible, we propose a best‐subset search, which also closely approximates a true exhaustive search. APES is made available in both as a standalone R package as well as part of the already existing mplot package.  相似文献

This article focuses on the Global Compact for Safe, Orderly and Regular Migration (GCM), a landmark international document that builds on the momentum of a decade of initiatives at the international level on migration governance, and its impact on Asia from the perspective of South Asia, Southeast Asia, China, and South Korea. While none of these countries voted against the adoption of the GCM, there are significant differences in how individual countries approached the commitments made in the GCM. These perspectives were articulated in a webinar hosted by Metropolis Asia on 20 June 2018 and in governmental statements made at the UN international conference when the GCM was adopted. This article also discusses the challenges confronting the implementation of the GCM. While the Compact resulted from inclusive and intensive negotiations and many compromises, the road towards realizing its goals will be at least as challenging as the road that led to its adoption. In spite of these challenges, the GCM is a ground‐breaking representation of the first multilateral framework for migration governance. Its success rests upon the recognition that addressing the challenges and maximizing the benefits of migration require true international cooperation, renewed commitment and meaningful action on the commitments agreed to.  相似文献

Because social media provide users with the possibility of an easy way to communicate with celebrities in society, it has become a more common practice to follow celebrities through social media. However, there exists few studies that examine how people’s individual characteristics are related to their celebrity-following behavior. In this regard, the current study examines whether celebrity followers’ loneliness is associated with the following behavior of their favorite celebrity. Data were collected through an online survey (N = 210). Primary findings suggest that celebrity followers’ loneliness is positively related to frequent visits of their favorite celebrity’s social media, greater social-interpersonal motive for following the celebrity, and greater enjoyment of learning about personal life stories of the celebrity. Social presence is found to be a significant moderator that can intensify more favorable parasocial relationship perceptions with the celebrity.  相似文献
