Perceived organizational support and coworker support as antecedents of foreign workers’ voice and psychological stress

This study investigates the effects of perceived organizational support (POS) and coworker support on the voice behavior and psychological stress of foreign workers in Macau hospitality industry. Drawing upon social exchange theory, we propose that POS and coworker support exert differential impacts on foreign workers’ promotive and prohibitive voice. We further hypothesize the negative relationships between these two types of support and psychological stress. Our hypotheses were tested by a two-wave longitudinal survey data collected from 141 foreign workers employed in four Macau hotels. The results showed that, although POS and coworker support were positively related to promotive voice, the effect of POS was comparatively stronger. Only POS had a significant and positive effect on prohibitive voice. In addition, coworker support but not POS reduced foreign workers’ psychological stress. The implications of these findings for research and practice are discussed.     

Convergence and divergence of role stress experience of locally hired Japanese and non-Japanese host country staff: a qualitative study

This qualitative study examines the role stress (comprising of role ambiguity and role conflict) experienced by locally hired Japanese (LJ) and non-Japanese (NJ) staff in a sample of Japanese companies in Australia. Expatriates were also interviewed to gather information regarding the impact of cross-cultural understanding on role ambiguity and role conflict in their work relationships with LJ and NJ staff. Both LJ staff and NJ local staff experienced two types of role ambiguity, resulting from insufficient English competence and information shortage. NJ staff experienced two additional types of role ambiguity due to their lack of cultural understanding about Japan. LJ staff experienced two types of role conflict which were not experienced by NJ local staff. These were caused by their cultural understanding about Australia, and their Japanese cultural heritage and understanding of the society and organisational processes. This study shows that cultural understanding of one's host country and parent country could reduce role ambiguity. In addition, it was found that cultural understanding of one's host country and parent country results in role conflict. These findings suggest that cultural understanding could have positive and negative consequences on role stress. Theoretical and practical implications in the management of white-collar staff in overseas Japanese companies are discussed.

工作分享对促进工作—生活平衡的作用研究

本文在分析工作分享理论和实践的基础上,剖析了我国实施工作分享的现实需求,提出了中国实施工作分享对促进企业员工工作—生活平衡的理论设想,并进行了实证研究,验证了实施工作分享可以缓解工作—家庭冲突、促进工作—生活平衡,一定程度上降低工作压力。工作分享理论是“以人为本”的管理理论,有利于员工全面发展,实现员工从“经济人”向“社会人”,再向“自我实现人”的发展,有利于建设积极的员工与企业的协调关系。     

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.     

Feminism’s fourth wave: a research agenda for marketing and consumer research

Abstract

Three waves of feminism each reveal a very different relationship with marketing. This commentary considers these relationships in the light of what is now frequently being hailed as the fourth wave, a resurgence of feminism that is driven by younger women who harness the power of the Internet and social media to challenge gender inequity. The commentary looks at what distinguishes the fourth wave from its predecessors and highlights key areas in marketing and consumer research where feminist perspectives are sorely required.
