COVID-19-induced layoff,survivors’ COVID-19-related stress and performance in hospitality industry: The moderating role of social support

The COVID-19 pandemic has hit the hospitality industry hard globally, resulting in millions of employees being laid off. Drawing upon the conservation of resources theory, this study aims to empirically examine how and when COVID-19-induced layoff influences employees’ in-role and extra-role performance in the hospitality industry. We tested this model by using field data collected from 302 employees and their supervisors in China across two waves. Results revealed that COVID-19-induced layoff increases survivors’ COVID-19-related stress, which in turn leads to decreased in-role and extra-role performance. The strength of these indirect effects is mitigated by perceived family support against COVID-19. Unexpectedly, perceived organizational support against COVID-19 intensifies these indirect effects. The theoretical and practical implications of this study are further discussed.

The triggers and clustering properties of merger waves

This article studies the triggers and the agglomeration of mergers and acquisitions (M&A) activity within clusters constituted by time, market and industry. Based on almost 500,000 individual transactions, we find that industry factors play a significant role in triggering activity and that M&A agglomerates strongly across related industries. While clustering in time turns out to be insignificant, stock market effects can be either an attracting or a repelling force, depending on the type of deal examined. This supports the view that merger waves are largely driven by industry shocks.     

非均匀生物介质中太赫兹光波传播特性的研究

为进一步了解太赫兹光波与生物介质的相互作用机理,采用蒙特卡罗法(MCM)对太赫兹光波在非均匀生物介质中的传播进行模拟计算,得到了太赫兹光波在非均匀生物介质表面的漫反射光强分布曲线.数据显示了漫反射光强分布与生物介质中异物的大小(R)及位置(D)的关系.     

倏逝波在一维氧化硅亚微米波导线中传输特性的研究

[HTK]基于光学倏逝波原理的光纤或波导传感器是目前光学传感器领域的重要发展方向之一,而倏逝波在其中的传输特性是决定该类传感器敏感特性的关键因数.利用倏逝场理论分析了直径102～103nm的一维氧化硅亚微米光波导在其直径与外部介质(折射率)变化时倏逝波的穿透深度.实验结果表明,亚微米光波导的传输损耗将随着波导尺寸和外部环境折射率的变化而变化,倏逝波的传输方式非常适用于高灵敏度探测,可应用于光化学传感器和生物化学传感器的设计.     

旅游专业学生酒店实习状况对其在酒店择业意向的影响分析

采用定量研究分析了学生酒店实习工作满意度和实习工作压力情况,并验证了实习工作满意度、实习工作压力与学生在酒店业择业的意向呈显著正相关、负相关。进一步探讨了学生在酒店业择业的意向回归模型。根据模型,旅游院校和酒店企业应做好学生的教育工作,使之更加全面、深入地认识酒店业和酒店实习。同时,提高实习生工作满意度,转化实习生工作压力,将有助于提高学生在酒店业的择业意愿。     

圆柱滚子轴承有限元分析

接触问题是一种典型的边界条件非线性问题。在分析接触问题时,使用Abaqus/standard模块,能正确模拟接触的过程,判断接触状态、输出接触压力。通过对圆柱滚子轴承在Pro/E中建立三维模型,然后导入ABAQUS软件进行接触分析,得出滚子与内、外圈之间接触应力的分布情况,和理论分析能很好地吻合,对轴承的选型具有指导意义。     

European bank stress test and sovereign exposures

We use an event study methodology to revisit the bank stress test conducted by the European Banking Authority in 2011. Instead of only considering the final results disclosure, we consider six key official announcements during the stress test. Our results indicate that abnormal returns reversed over the course of the stress test and that the emerging sovereign crisis contributed to the stock market perception of bank health.

The Relationships Between Emotional Intelligence,Job Stress,and Quality of Life Among Tour Guides

Considerable evidence supports the notion that higher job stress is associated with lower quality of life (QOL), which is an increasingly common indicator to assess an individual's general health status, mental health and well-being. Those with higher emotional intelligence (EI) levels are more aware of their emotions and have more effective coping strategies to deal with stress-related emotions, all of which lead to higher levels of well-being. The purpose of this study is, therefore, to explore the relationships between EI, job stress and QOL among tour guides, who significantly influence tourists' impressions of a destination. The obtained results indicated that EI was inversely correlated with occupational stress and positively associated with QOL, and a negative link was seen between job stress and QOL. In practice, the results can provide information for developing interventions to enhance tour guides' competencies of EI and stress management, which result in higher levels of QOL.
