流域综合管理认知度的量化调查和层级差异分析——以长江流域为例

长江流域自然条件复杂,经济发展不均衡,长期的资源消耗和环境污染,使流域管理面临体制、机制、形式、方法、手段等种种挑战,流域综合管理是公认的改革方向。从法律法规、协调机制、信息共享、公众参与4个角度观察长江流域的管理现状,收集原始信息,采用定量分析,剖析国家、省、流域3个层面的认知差异,分析结果可为辨识流域管理的薄弱环节及选择改革的突破点提供量化支撑。     

人工神经网络产量定量评价模型在县域耕地地力评价中的应用

以辽宁省彰武县为研究对象,在AHP-模糊评价方法的基础上尝试建立耕地地力的ANN-产量定量评价模型。与传统方法相比,模型不需要确定权重,并且能够反映耕地地力评价的非线性特征,消除了传统方法确定权重时人为因素的影响,增加了评价结果的客观性。通过与传统方法的对比发现,得到了较为一致的评价结果,为耕地地力的定量评价探索了一条新的道路。     

新冠肺炎疫情下管理层业绩预告归因行为研究

基于A股上市公司2020年1—4季度业绩预告归因的研究发现,公司将业绩变化归因于新冠疫情的概率呈现随季度下降的趋势,坏消息归因于新冠疫情的概率显著高于好消息,且这种差异未随季度发生显著变化。业绩预告归因反映了管理层自利性归因与新冠疫情的叠加影响,且在特定情境下投资者能够识别自利性归因。研究结论从微观经济主体和利益相关者感知的角度展示了中国抗击新冠疫情的成效,也为监管部门规范重大外生冲击下的信息披露操纵行为提供了借鉴。     

量化思维在绿色建筑设计教学中的应用研究

Does travellers’ casual attribution affect pre-recovery emotions and behavioural intentions? A field study of airline travellers in Malaysia

This study examines the relationship between airline travellers' casual attribution, pre-recovery emotions, and negative behavioural intentions after a service failure and proposes a model for analysing direct effects of airline travellers' casual attribution of stability (failure frequency) and controllability (the extent to which the airline can control the failure) on negative behavioural intentions as well as its indirect effects through pre-recovery emotions. Data were gathered through a survey of airline travellers who experienced a failure in the past six months. The results indicate that both dimensions of casual attribution influenced pre-recovery emotions and negative behavioural intentions, and that pre-recovery emotions were significantly related to negative behavioural intentions. In addition, the results verify the mediating effect of pre-recovery emotions on the relationship between casual attribution and behavioural intentions. These results have important managerial implications.     

An experiment on the role of tourist attribution: Evidence from negative nature-based incidents

More so than previously, in recent years tourists have been exposed to unexpected adverse situations, such as political instability, caused by the destination. Many aspects of the destination experience do not involve service delivery and product consumption; thus, such an experience needs to be treated uniquely. Acknowledging that the effects of tourists’ inner psychological processes in this context are crucial, this study applies attribution theory to examine how tourists make sense of negative incidents caused by the destination’s natural incidents. The results show the crucial effects of globality attribution in predicting the levels of satisfaction.     

How Media Coverage of Corporate Social Irresponsibility Increases Financial Risk

Research summary: This article explores the relationship between corporate social irresponsibility (CSI) and financial risk. We posit that media coverage of CSI generates risk by providing conditions that increase the potential for stakeholder sanctions. Through analyzing an international panel of 539 firms during 2008–2013, we find that firms receiving higher CSI coverage face higher financial risk. We show that the reach of the reporting media outlet is a critical condition for this relationship. Once the outlet has a high reach, the severity of CSI coverage is a boundary condition that further reinforces the effect. Our findings complement existing theory about the risk‐mitigating effect of corporate social responsibility by illuminating the risk‐generating effect of CSI coverage. For executives, these insights suggest complementary strategies for corporate risk management. Managerial summary: This article examines the effect of negative news on financial risk. It shows that negative media articles regarding environmental, social, and governance (ESG) issues increase a firm's credit risk. It also provides a detailed analysis of the impact of an article's reach and severity, i.e., how many readers are exposed to the article and how harshly it criticizes the firm. The results allow to quantitatively assess the risk that emanates from negative ESG news. For executives, three strategies are derived for limiting a firm's exposure to this risk: balancing corporate social responsibility programs with operational safety programs, reporting suboptimal environmental and social performance transparently and proactively, and avoiding acquisition targets and markets with a legacy of negative news.
