The Role of Emotions in Risk Communication

We present two experiments investigating the role of emotions concerning technological and natural hazards. In the first experiment, technological hazards aroused stronger emotions, and were considered to be riskier than natural hazards. No differences were found between the texts versus audio presentations. However, the presence of pictures aroused stronger emotions and increased the perceived risk. Emotions play a mediating role between hazard types and perceived risk, as well as between pictures and perceived risk. The second experiment adopted real‐world materials from webpages and TV. Emotions again play a mediating role between pictorial information and risk perception. Moreover, specific emotions were found to be associated with different types of action tendencies. For example, loss‐based emotions (e.g., fear, regret) tend to lead to prevention strategies, whereas ethical emotions (e.g., anger) lead to aggressive behavior. We also find that loss‐based emotions in the technical hazard scenario trigger more coping strategies (from prevention to retaliation) than in the natural hazard scenario.     

Why Aesthetic Patterns Matter: Art and a “Qualitative” Social Theory

This paper argues that an explanation of the role of aesthetic patterning in human action needs to be part of any “qualitative” social theory. It urges the social sciences to move beyond contextualism and to see art as visual, acoustic and other media that lead to heightened sensory perception and the coordination of feelings through symbols. The article surveys the argument that art provides a basic model of how the self learns to interact with external environments; and the complementary thesis that art could be seen as integral to the emergence of systems of human knowledge, communication and economy. Ornamentation and stylization are advanced as two concrete devices through which human attention is captured and experience is ordered through aesthetic patterns. The conclusion is drawn that art offers the social sciences a meaningful account of the perceptual or “qualitative” dimensions of social interactions; and that this is much needed today.

“民工荒”现象的经济学解释——基于劳动力供需双方知觉的分析

我国东南沿海地区出现的“民工荒”是有悖于经济学常理的现象,主要原因在于劳动力供需双方知觉上存在的偏差,导致劳动力价格上存在太大的差距。要解决“民工荒”问题,就必须从政府、企业及民工三方面着手,尽量缩小劳动力供需双方知觉上存在的偏差。     

A Simple Formula for Calculating the "Mass Density" of a Lognormally Distributed Characteristic: Applications to Risk Analysis

Statements such as "80% of the employees do 20% of the work" or "the richest 1% of society controls 10% of its assets" are commonly used to describe the distribution or concentration of a variable characteristic within a population. Analogous statements can be constructed to reflect the relationship between probability and concentration for unvarying quantities surrounded by uncertainty. Both kinds of statements represent specific usages of a general relationship, the "mass density function," that is not widely exploited in risk analysis and management. This paper derives a simple formula for the mass density function when the uncertainty and/or the variability in a quantity is lognormally distributed; the formula gives the risk analyst an exact, "back-of-the-envelope" method for determining the fraction of the total amount of a quantity contained within any portion of its distribution. For example, if exposures to a toxicant are lognormally distributed with σ_{in x}= 2, 50% of all the exposure is borne by the 2.3% of persons most heavily exposed. Implications of this formula for various issues in risk assessment are explored, including: (1) the marginal benefits of risk reduction; (2) distributional equity and risk perception; (3) accurate confidence intervals for the population mean when a limited set of data is available; (4) the possible biases introduced by the uncritical assumption that extreme "outliers" exist; and (5) the calculation of the value of new information.     

音乐情绪感知的脑电研究

利用情绪量表筛选出对应愉快、快乐、悲伤、恐惧四种情绪的音乐片段作为刺激,同步记录脑电,从脑区、情绪极性、强度等方面对脑电α波功率的变化进行了分析。结果表明:脑电α波功率的变化与情绪的极性和强度密切相关;快乐与恐惧、愉快与恐惧、恐惧与悲伤之间α波功率差异显著;顶枕区α波功率在负极性情绪中强度强的明显小于强度弱的;在强度强的情绪中,正极性情绪显著大于负极性情绪。

Risk,Media, and Stigma at Rocky Flats

Public responses to nuclear technologies are often strongly negative. Events, such as accidents or evidence of unsafe conditions at nuclear facilities, receive extensive and dramatic coverage by the news media. These news stories affect public perceptions of nuclear risks and the geographic areas near nuclear facilities. One result of these perceptions, avoidance behavior, is a form of "technological stigma" that leads to losses in property values near nuclear facilities. The social amplification of risk is a conceptual framework that attempts to explain how stigma is created through media transmission of information about hazardous places and public perceptions and decisions. This paper examines stigma associated with the U.S. Department of Energy's Rocky Flats facility, a major production plant in the nation's nuclear weapons complex, located near Denver, Colorado. This study, based upon newspaper analyses and a survey of Denver area residents, finds that the social amplification theory provides a reasonable framework for understanding the events and public responses that took place in regard to Rocky Flats during a 6-year period, beginning with an FBI raid of the facility in 1989.     

Methodological Approaches to Assessing Risk Perceptions Associated with Food-Related Hazards

The psychometric approach developed by Slovic and his co-workers has been effectively used to assess risk perceptions associated with different food-related hazards. However, further examination (using questionnaire data and partial correlation techniques) has indicated that technological hazards are highly differentiated from lifestyle hazards, in terms of both hazard control and knowledge about the hazard. Optimistic bias was also seen to vary between hazards. Further research has focused on a particular hazard, genetic engineering. Risk perceptions associated with genetic engineering are underpinned by ethical concern and questions relating to perceived need for the technology, as well as perceptions of risk or harm. However, increasing the specificity of hazard stimuli was found to alter the factor structure of underlying risk perceptions. The utility of preference mapping procedures in determining individual differences in trust in risk regulators is also discussed.
