Group‐analytic network process for balancing stakeholder views on fire protection of steel‐framed buildings

To select appropriate fire protection options for buildings during their design stage, economic, safety, environmental, and societal criteria need to be accounted for. The divergent and sometimes conflictual desires from different fire design stakeholders involved in the process present a multicriteria decision problem. Design decision criteria and fire protection options can be interdependent, and so there is a need to manage these desires with an advanced decision analysis technique, thereby reducing uncertainties in the complex decision‐making process. The aim of this paper is to use the weighted/geometric mean method‐analytic network process (W/GMM‐ANP) to balance the opinions of fire design stakeholders extracted from 42 structured stakeholder interviews on selecting the most suitable fire protection option for buildings constructed of steel frames. Different categories of interdependent decision elements were developed from 22 design decision criteria and 5 proposed fire protection options to produce a network of decision clusters for multicriteria decision analysis. In the synthesis and ranking of fire protection options, the W/GMM‐ANP accounted for the multiple interdependencies of weighted and unweighted stakeholder desires and managed the complexity of the decision‐making problem. The technique is proposed for approaching suitable group decisions in structural fire design of steel‐framed buildings as well as other performance‐based engineering decision making that may involve multidisciplinary stakeholders.     

中庸价值取向对员工变革行为的情景依存作用

中庸是一种价值取向, 它倡导在全局认知基础上采用执中和适度的方式, 达到个体与环境的和谐。以49个企业团队的413名员工为研究对象, 采用多层次线性模型考察中庸价值取向在不同情境下对员工变革行为的影响。结果显示当员工具有高变革认知时, 中庸价值取向对员工变革行为有显著促进作用; 当团队中存在高同事消极约束时, 中庸价值取向对员工变革行为有显著消极作用; 模范带头作用没有显著情景作用。研究揭示了中庸价值取向影响员工变革行为是依据情景而变化, 从而达到个体与环境的和谐。     

Do military decision makers behave as predicted by prospect theory?

Four experiments were conducted to explore the robustness of risky choice framing among military decision makers. In the first experiment the original version of the Asian disease problem was administered. In contrast to Tversky and Kahneman's ( 1981 ) original findings, military decision makers were not influenced by the gain and loss framing. They demonstrated risk‐seeking behavior in both domains. In the second experiment, we administered a military version of the Asian disease problem. We found a significant framing effect, but it was unidirectional: The decision makers were risk seeking in both domains, but significantly more risk seeking in the loss domain. To explore the strength of this risk‐seeking preference, we altered the problem in a third experiment, making the risky alternative 12.5% less attractive than the certain one. Again, we found risk‐seeking behavior in both domains. Finally, we explored reasons for these deviations from prospect theory by comparing the responses of business students and military officers. In this analysis, we observed significantly higher levels of self‐efficacy in the military sample, as compared to the civil sample, and that the self‐efficacy influenced risk seeking only in the military sample. In a post hoc analysis we also found that years of education reduced risk‐seeking preference. Implications and directions for future research are discussed.

时间压力的双刃效应及其作用机制

时间压力是现代社会中人们经常面对的重要问题。以往研究认为时间压力只会产生消极影响, 然而现有研究发现时间压力也会产生积极影响。总结以往研究, 介绍了时间压力的概念和测量方式, 分别阐述了时间压力的损耗作用和促进作用, 并用注意焦点理论、激活理论、维生素模型和挑战?阻碍模型等理论解释时间压力的双刃效应。未来研究应该进一步关注：(1)基于时间心理账户开展时间压力的分类研究; (2)时间压力促进作用的动机和情绪双路径机制; (3)探寻有效缓解时间压力损耗作用的机制。     

归纳推理属性效应中背景关系提取原则的探究

本实验以生态关系、类别关系和无关三类项目为推理背景, 以基因X和疾病Y为不同的推理属性, 通过考察实验材料快速或延迟呈现时对推理可能性和推理信心的影响来探究属性效应中背景关系提取的原则。结果发现实验材料快速和延迟呈现时对推理可能性无显著影响, 但对推理信心有显著影响, 快速呈现时被试的推理信心显著高于延迟呈现时。由此可以认为归纳推理属性效应中人们优先按照相关性原则提取背景关系, 同时该结果还表明属性效应既有跨文化的普遍性也有其文化特殊性。     

高级职业经理人的职业枯竭状况及其与工作压力的关系

本研究使用问卷法,对1555名高级职业经理人的职业枯竭状况进行了分析,考察了各种人口统计学变量之间的差异,并探讨了职业枯竭的各维度与工作压力的关系。结果发现:高级职业经理人的职业枯竭水平在性别、年龄、学历、婚姻状况、职位等人口统计学变量上存在着显著差异;各工作压力源中,除人际关系外,可分别预测职业枯竭的三个维度,其中对于耗竭维度的预测度最高。     

应激干预对不同行为类型大学生心率血压手指温度的影响

探讨应激干预对心率、血压、手指温度的影响及不同行为类型的差异。被试为河北师范大学本科生72人(A、B型各36人),应激干预为音乐放松、腹式呼吸和静坐休息,实验包括基线期-干预期-应激期-恢复期四个阶段,在观看紧张性影片前进行应激前干预,记录被试的心率、血压、手指温度。结果发现,就缓解应激所产生的交感神经活动增强来说,音乐放松效果较好,腹式呼吸也明显优于自然休息;行为类型（A、B）和应激干预大多表现出来交互作用;个体生理反应的性别差异与生理指标有关,基线值的性别差异较大时,男女生的生理数据不宜混合在一起,基线值相差不大时,可以用相对值（如变化值或变化率）进行统计处理。说明行为类型（A、B）对于应激而言是一种微调变量,在自然休息状态或者低应激水平下作用更明显,应激水平较高时,行为类型的调节作用会显著降低;不同应激干预适用不同行为类型个体     

Managing intergroup attitudes among Hong Kong adolescents: Effects of social category inclusiveness and time pressure

Previous research has shown a widespread bias among Hong Kong adolescents against Chinese Mainlanders. Based on social identity and social cognitive theories, we examined the effects of identity frame switching (situational induction of social category inclusiveness) and time pressure (environmental constraints on social information processing) on Hong Kong adolescents' attitudes toward Chinese Mainlanders. Results indicated that Hong Kong adolescents had acquired a habitual tendency to make social comparisons within an exclusive regional framework of reference. This habitual tendency might lead to negative judgment biases toward Chinese Mainlanders, particularly when the adolescents made social judgments under time pressure. In addition, switching to an inclusive national frame of reference for social comparison attenuated negative intergroup attitudes. The theoretical implications of these findings are discussed.     

Effects of time pressure on strategy selection and strategy execution in forced choice tests

We examined the effects of cognitive load on the strategy selection in the forced choice test (FCT) when used to detect hidden crime knowledge. Examinees (N = 120) with and without concealed knowledge from a mock crime were subjected to an FCT either under standard circumstances or cognitive load. Cognitive load was implemented through time pressure. The FCT distinguished examinees with concealed knowledge from those without better than chance in both conditions, but the counterstrategies did not differ between conditions. Further investigation revealed that time pressure did affect examinees' ability to follow their intended counterstrategy to produce randomized test patterns, which constitutes an effective counterstrategy in the FCT. Hence, time pressure lowered the success rate of effective counterstrategies, but not their incident rates. Further disambiguation of various cognitive load manipulations and their effects on strategy selection and execution is needed.     

L’intensification du travail,et l’intensification des changements dans le travail : quels enjeux pour les travailleurs expérimentés ?

In this article we address, on the basis of various knowledge in ergonomics, work psychology and work demography, the stakes of a confrontation between two trends in progress: on one side the structural ageing of workforce, on the other side work intensification, and intensification of changes at work. This analyze includes statements on these evolutions by themselves, and a synthesis of knowledge on the difficulties created by the intensification of work, or changes at work, for elderly workers, but also on work strategies that those can elaborate, using their experience, in order to cope with these constraints.
