考虑后悔与失望心理的应急救援任务匹配方法

为研究区间犹豫模糊信息下的应急救援任务匹配问题,提出考虑救援人员与受灾群众后悔与失望心理的决策方法以及确定双边主体效用值的方法,基于后悔理论与失望理论获得双边主体的后悔值与失望值,确定双边主体的综合感知效用值,并构建最大化综合感知效用值的多目标匹配优化模型,以得到最优匹配结果。研究结果表明：后悔与失望心理对双边主体的心理感知具有重要影响,但不影响最优匹配结果。研究结果可为应急救援任务匹配提供理论支持。

乌鲁木齐市大气中二氧化硫的灰色预测

根据灰色系统理论,联系乌鲁木齐市大气环境的实际状况,建立了精度检验为一级的灰色预测模型,经模型检验其精度完全满足要求。对乌鲁木齐大气中的SO2值进行预测分析的结果表明,乌鲁木齐市大气中SO2值呈上升的趋势,在未来几年中,乌鲁木齐市大气中SO2的预测值超过国家三级标准值(即大气中SO2的质量浓度年均值≤0.10mg/m3),这种发展趋势应引起有关部门的关注。     

An application of a modified theory of planned behavior model to investigate adolescents’ job safety knowledge,norms, attitude and intention to enact workplace safety and health skills

Introduction: For many reasons, including a lack of adequate safety training and education, U.S. adolescents experience a higher rate of job-related injury compared to adult workers. Widely used social-psychological theories in public health research and practice, such as the theory of planned behavior, may provide guidance for developing and evaluating school-based interventions to prepare adolescents for workplace hazards and risks. Method: Using a structural equation modeling approach, the current study explores whether a modified theory of planned behavior model provides insight on 1,748 eighth graders’ occupational safety and health (OSH) attitude, subjective norm, self-efficacy and behavioral intention, before and after receiving instruction on a free, national young worker safety and health curriculum. Reliability estimates for the measures were produced and direct and indirect associations between knowledge and other model constructs assessed. Results: Overall, the findings align with the theory of planned behavior. The structural equation model adequately fit the data; most path coefficients are statistically significant and knowledge has indirect effects on behavioral intention. Confirmatory factor analyses suggest that the knowledge, attitude, self-efficacy, and behavioral intention measures each reflect a unique dimension (reliability estimates ≥0.86), while the subjective norm measure did not perform adequately. Conclusion: The findings presented provide support for using behavioral theory (specifically a modified theory of planned behavior) to investigate adolescents’ knowledge, perceptions, and behavioral intention to engage in safe and healthful activities at work, an understanding of which may contribute to reducing the downstream burden of injury on this vulnerable population—the future workforce. Practical application: Health behavior theories, commonly used in the social and behavioral sciences, have utility and provide guidance for developing and evaluating OSH interventions, including those aimed at preventing injuries and promoting the health and safety of adolescent workers in the U.S., who are injured at higher rates than are adults.     

The passion bug: How and when do leaders inspire work passion?

Drawing from signaling theory, we propose a work passion transfer model where leaders' passion is transmitted to employees through the former's leadership style and is contingent on employees' perceived importance of performance to self-esteem (IPSE). Data from 201 supervisor–employee dyads from the health-care industry show that leaders' harmonious passion led to employees' harmonious passion through charismatic leadership, whereas contingent reward leadership accounted for the transfer of obsessive passion; IPSE did not play a moderating role for either form of passion. Results from a supplementary study further reveal that the link between leadership and employee passion operated through employees' perception of leader passion and that employees' IPSE accentuated for the relationship between perceived leader obsessive passion and employees' obsessive passion. This study advances research in work passion, leadership, and signaling theory and provides important implications for managerial practice.
