调水工程生态补偿研究与实践进展

生态补偿机制及其建立作为目前生态经济学领域研究的热点,其在调水工程中的作用也越来越受到社会的广泛关注。分析了生态补偿的概念发展、理论基础和国内外调水工程及水源区生态补偿的研究与实践。结果表明:调水工程生态补偿是通过政府主导和市场作用共同实现的,通过生态补偿机制促进相关利益主体共同参与是实施调水工程有效管理、保障调水工程高效运行的重要途径。     

日本新冠疫情的社会影响与政策选择

新冠病毒疫情对日本社会各个方面都产生了严重的影响。疫情防治本身就属于社会政策范畴。总体而言,日本作为东方国家所实施的防疫政策取得较好效果,但同时也存在着一些问题。相对宽松甚至曾经数度放缓的防疫政策使日本错过了疫情治理的最佳时机,因而导致疫情的长期化。实现经济复苏是日本政府关注的重点,规模空前的经济刺激政策与以防疫为主导的社会政策之间既有结合也存在矛盾。日本政治的变化具有长期的社会基础,新冠疫情的暴发与蔓延使其凸显出来。在新的国际格局条件下,日本面临着外交战略方向的重大选择。     

基于Copula变点检测的美国次级债金融危机传染分析

金融危机传染的分析是国际金融研究中的重要问题,大多数传染效应存在性的检验采用相关性方法,本文通过阿基米德Copula的变点检测方法来检验传染效应的存在性,更加全面地分析了国家收益率之间的相依结构,并以两个国家收益率的尾部相依指数作为传染程度大小的一种度量。最后对亚洲几个主要市场的指数和S&P500指数数据进行了实证分析,研究美国次级债金融危机对亚洲市场的传染效应。     

江苏省生态足迹和经济增长的动态特征

采用协整分析、误差修正模型、脉冲响应和方差分解等计量经济方法,分析了生态足迹与经济发展的相互关系和相互作用,以协调经济发展与资源约束之间的矛盾。结果表明:(1)GDP与总生态足迹、能源足迹、耕地足迹、林地足迹之间存在长期均衡关系,但短期却存在失衡。(2)经济发展对自身波动和总生态足迹的冲击响应强烈,而对来自耕地足迹的冲击响应微弱。(3)从影响大小程度来看,经济自身的波动在短期对经济发展影响十分显著;但在长期,林地足迹和总生态足迹的提高对经济发展具有显著的决定关系。     

习近平生态文明思想“十个坚持”的哲学意蕴

习近平生态文明思想“十个坚持”的基本命题具有严密的逻辑结构和深厚的哲学意蕴，其从马克思主义自然观、认识论和实践论三个基本维度进行思想体系构建。其以人与自然和谐共生的自然观为思想原点，解决了“为什么建设生态文明”的元哲学问题；以生态历史观、生态发展观、生态民生观等为逻辑展开，从文明形态、发展道路、价值立场等方面进行了“建设什么样的生态文明”的理论建构；以生态政治领导观、生态系统治理观、生态法治观、生态全民行动观、生态全球共赢观等为方法论指导，回答了“怎么建设生态文明”现实问题，为建设美丽中国提供了总的遵循，为建设美丽世界和发展中国家生态文明建设提供了中国理念和中国方案。     

Finding the path beyond reputation repair: A structural topic modeling analysis of the crisis communication paradigm in public relations

This research utilizes computational methods to examine crisis communication scholarship from 2010 to 2020 in two studies with a census of all articles in Public Relations Review and the Journal of Public Relations Research (n = 1293 articles, 7400,685 words). Results indicate crisis scholarship has expanded beyond its prior focus on reputation repair. Situational crisis communication theory and image repair are compared in volume of scholarship and methodological affinity. Social media, SCCT, and media relations are identified as central topics within crisis communication scholarship.     

Warranted inferences of mediation and possibility of a threshold effect: Verifying the mediating effects of anger in situational crisis communication theory

Scholars have called for communication research to verify the causal claims of mediation models from a research design perspective, instead of only proving mediation statistically. This study validates whether and how anger mediates the causal effects of crisis types on publics’ responses in Situational Crisis Communication Theory (SCCT), including reputation, negative word-of-mouth intention, and purchase intention in China. Two experiments were conducted based on the experimental-causal-chain design. Results in Study 1 demonstrate that the causal relationships between three crisis types and publics’ emotional and other responses in China are consistent with findings in Western contexts. In Study 2, the results of a 2 (anger: low, high) x 3 (crisis types: victim crisis, accidental crisis, preventable crisis) factorial experiment reveal significant mediating effects of anger on publics’ responses in the victim and accidental crisis conditions, but not for preventable crises. This novel finding suggests the possibility of a threshold effect of anger in the mediating process. Specifically, anger has a mediating effect on publics’ responses when it is below the high-anger threshold. However, anger may no longer be the mediator when it exceeds this threshold. This finding empirically challenges the common assumption that emotions have a linear relationship with publics’ responses, thus offering a new research avenue and deeper understanding of how emotions function in crises. Therefore, this research serves as a pioneer, calling for future studies to validate other theories involving mediation to yield fruitful insights.

Traversing the storm: An interdisciplinary review of crisis leadership

An organizational crisis is a low-probability, high-impact event that threatens the survival of organizations and individuals, often with little warning. In response, people seek clarity, reassurance, and hope from organizational leaders. Yet, crises also vary in nature and impact (e.g., a product failure versus the COVID-19 pandemic), which presents diverse challenges to leaders and differing stakeholder perceptions. Based on a critical analysis of 69 empirical articles, we provide a comprehensive, systematic, interdisciplinary review of the crisis leadership literature. Our review utilizes the Coombs and Holladay (1996) crisis typology, where crises are categorized according to mutually exclusive attributional dimensions (i.e., internal–external and intentional–unintentional). We conduct a thematic analysis of crisis leadership within and across these four crisis categories and find that each is associated with a different leadership theme. We also examine the methodological quality and rigor of the qualitative and quantitative articles in our review. Based on our findings, we also offer suggestions to guide future crisis leadership research, and provide guidance for organizational leaders in how to respond to various crises.     

Presidential crisis: An analysis of Biden & Trump’s crisis communications strategies in response to allegations of sexual misconduct

While campaigning for president of the United States, both Donald Trump (2016) and Joe Biden (2020) faced serious allegations of sexual misconduct. Consequently, the sexual misconduct allegations were classified as a crisis for the candidates themselves and their campaigns. This study identified the crisis communications strategies that each individual and their respective campaign utilized, analyzing the ways in which each candidate adhered to and deviated from the established framework of the crisis communications model (Strategic Crisis Communications Theory) (Coombs, 1995). Artifacts during the campaign season such as statements, press releases, responses, and news articles were collected and analyzed under the framework of the SCCT. Research indicates that each candidate was able to utilize “mismatched” strategies successfully, suggesting that the SCCT may be applied in political contexts. More research is needed to better understand the role SCCT plays in the political realm--especially within political organizations and campaigns.
