Media Disaster Reporting Effects on Public Risk Perception and Response to Escalating Tornado Warnings: A Natural Experiment

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.     

Developing a Broadly Applicable Measure of Risk Perception

Decades of research identify risk perception as a largely intuitive and affective construct, in contrast to the more deliberative assessments of probability and consequences that form the foundation of risk assessment. However, a review of the literature reveals that many of the risk perception measures employed in survey research with human subjects are either generic in nature, not capturing any particular affective, probabilistic, or consequential dimension of risk; or focused solely on judgments of probability. The goal of this research was to assess a multidimensional measure of risk perception across multiple hazards to identify a measure that will be broadly useful for assessing perceived risk moving forward. Our results support the idea of risk perception being multidimensional, but largely a function of individual affective reactions to the hazard. We also find that our measure of risk perception holds across multiple types of hazards, ranging from those that are behavioral in nature (e.g., health and safety behaviors), to those that are technological (e.g., pollution), or natural (e.g., extreme weather). We suggest that a general, unidimensional measure of risk may accurately capture one's perception of the severity of the consequences, and the discrete emotions that are felt in response to those potential consequences. However, such a measure is not likely to capture the perceived probability of experiencing the outcomes, nor will it be as useful at understanding one's motivation to take mitigation action.     

“I feel and think,therefore I am”: An Affect-Cognitive Theory of management decisions

I propose an Affect-Cognitive Theory to comprehensively understand how decisions occur in organizations. To this aim, I first review the assumptions of sensemaking and decision-making streams of research, especially the influence of bounded rationality, affective states and their relationships with cognition; then, I integrate them on the common basis of socially situated cognition. This new theory emphasizes the role of affective states in determining/being determined by cognition and its errors, pointing out decision makers’ affect as the result of multi-level adaptations to the physical and social environment. Management decisions are path dependent but not immutable; they, indeed, bank on the predominant feeling resulting from the modifying interactions and regulations of decision makers with their physical and social environment. Here, decision makers are proposed as “emotional cognizers” overcoming the thinking-feeling dichotomy that has often featured in the study of management decisions. This theory is beneficial for behavioral strategy, offering the needed assumptions to intertwine human cognition, emotions, and social behavior.

唐代文学中灾异观念的表现

灾异观念是天人感应学说的重要内容,唐人因为推崇汉朝,对来自汉朝的思想观念接受较多,灾异观念在唐代甚为流行,其表现形式与汉朝略有不同。对文学创作的影响主要表现在政论、对策和诗歌中,该观念对唐代文学的作用小于瑞应和封禅。

论人与自然的本原性和谐--自然之所以美的一个重要原因

以往的种种自然美理论 ,特别是“自然人化”说都程度不同地忽略了自然之所以美的一个重要原因 :人与自然的本原性和谐。它是人与自然的一种主要由血缘决定的自然而然、发自内心、不言自明、近似本能性的特殊的情感关系。“黄金时代”史前研究为其奠定了史前史的发生学基础 ,“归依体验”理论为其提供了审美心理学的印证 ,“回归自然”的主张和实际行动为其出具了历史实践证明 ,著名思想家的代表性论述为其积累了极富启迪的思想资料。     

Unmanaging public relations: Reclaiming complex practice in pursuit of global consent

Globalisation raises numerous problems for contemporary public relations theory. In a world where the geographic reach of organisations routinely spans cultures and nation states and where issues of culture, economics and politics are inseparably intertwined, the discipline of public relations has established a distance from the immediacy of the marketplace, failed to fully engage with discussions of culture. By taking a relentlessly managerialist approach, theorists have also failed to recognise the true complexity of public relations practice and this has marginalised aspects of practice that, though nebulous and intangible, are none the less real. This paper argues that attention needs to shift towards the complexities of practice, in order to recapture and theorise a distinctive occupational field with the aim of better understanding the relationship between universal humanising principles, on the one hand, and the purposive demands of capital, on the other; the attempt to theorise how public relations makes profitable sense in society. The paper was prompted by the author's reflections on auto-ethnographic research into the public relations field, part of an ongoing research project.     

现代主义诗歌先锋性困苦的动因阐释

先锋性困苦是现代主义文学一个突出的表现。在中国现代主义诗歌中,先锋性自身特性,先锋性叛逆传统又受传统制约、批判现实又被现实压抑、抗拒偏见又逃不出偏见、超越庸常又难以实现真正个体存在,这种种围困和两难处境,决定现代主义诗歌先锋性困苦成为必然,且注定没有退却的余地。分析、思考这种困苦动因,对历史和当下颇具意义。
