基于产业结构调整的服务业发展定位研究--以黑龙江省为例

通过计算黑龙江省产业相对劳动生产率和产业结构偏离度可知黑龙江省产业结构不合理和失衡的问题严重。构建的计量模型分析表明,在黑龙江省,服务业对经济发展的贡献处在三次产业的最末位,因此,加快服务业的发展势在必行,而找准服务业的发展定位就是其中的关键。黑龙江省应该加快农林牧渔服务业的发展、优先发展现代商贸流通服务业、积极推进现代旅游业尤其是特色旅游业的发展,以促进产业结构的优化。     

Subjective fit with organizational culture: an investigation of moderating effects in the work stressor-employee adjustment relationship

Occupational stress has been a concern for human resource managers in light of research investigating the work stressor-employee adjustment relationship. This research has consistently demonstrated many negative effects between stressors in the workplace and employee adjustment. A considerable amount of literature also describes potential moderators of this relationship. Subjective fit with organizational culture has been established as a significant predictor of employee job-related attitudes; however, research has neglected investigation of the potential moderating effect of subjective fit in the work stressor-employee adjustment process. It was predicted that perceptions of subjective fit with the organization's values and goals would mitigate the negative effect of work stressors on employee adjustment in an employee sample from three organizations (N = 256). Hierarchical multiple regression analyses revealed support for the stress-buffering effects of high subjective fit in the prediction of physical symptoms, job satisfaction, and intentions to leave. The theoretical and practical implications of the results are discussed.     

Expatriates social networks: the role of company size

This study is an extension as well as a test of Caligiuri and Lazarova's model (2002) for the influence of support provided by different network partners (supervisors, co-workers, friends, spouses) on received socio-emotional and instrumental support. We extended this model by examining this relationship in connection with company size. Ninety expatriates were questioned during their foreign assignment: 45 from small and medium-sized enterprises and 45 from large companies. Consistent with our hypothesis expatriates who received support from their co-workers during their foreign sojourn also received more instrumental support. In addition, the type of company moderated the relationship between the network partner friends and socio-emotional and instrumental support. Implications for expatriate adjustment research and practice are discussed.     

The effects of cultural intelligence on expatriate performance: the moderating effects of international experience

In recent years, cultural intelligence (CQ, or the ability that an expatriate has to adapt across cultures), cultural effectiveness (the ability to interact and communicate with host nationals), and cultural adjustment are regarded as three of the most important factors for expatriate performance. However, the interrelationships between these variables have largely been ignored. Moreover, the role of previous international experiences on the above interrelationships has also not been determined. This study focuses on how CQ and expatriates' experience affects cultural adjustment, cultural effectiveness, and expatriates' performance. The results reveal that the positive effect of CQ needs to be mediated by cultural adjustment and cultural effectiveness before affecting expatriate performance. Furthermore, expatriates' prior international working and travel experiences moderate the effects of CQ on cultural adjustment and cultural effectiveness.     

The relationships of organizational justice,social exchange,psychological contract,and expatriate adjustment: an example of Taiwanese business expatriates

In the field of international human resource management, studies have seldom examined organizational justice, social exchange, and psychological contract together as important factors in influencing the expatriate adjustment process. The purpose of this research is to fill the research gap by examining these factors and their relationships with expatriate adjustment. The researcher conducted a survey of Taiwanese business expatriates during the first quarter of 2007, collecting 219 valid samples for analysis. A hierarchical regression model was used to test the research framework hypotheses, which showed that expatriates' perception of organizational justice has a positive influence both on their perceptions of social exchange and on their psychological contract fulfillment. Expatriates' perceived that social exchange has a positive influence on their perceptions of psychological contract fulfillment and foreign adjustment. Finally, research implications are discussed and future study suggestions are recommended.     

Does cross-cultural adjustment coincide with career capital growth? Evidence from Vienna,Austria

Using a sample of 154 employed expatriates, who have lived in Vienna, Austria, for up to 10 years, this paper explores if and to what extent career competency growth and cross-cultural adjustment coincide. Cognitive and affective aspects of cross-cultural adjustment to relationships, day-to-day interactions and general living conditions are analysed. The study uncovers details about the relationship between the cognitive and affective dimensions of cross-cultural adjustment and the development of knowing-how, knowing-whom and knowing-why. The most important result is that principally the affective dimension of cross-cultural adjustment relates to gains in career capital.     

The adjustment process of Spanish repatriates: a case study

Little empirical research has focused on the repatriation process of international employees despite the increasing number of expatriations that take place and the consequences of its failure. Based on a ten cases study, this research provides an in-depth analysis of the adjustment difficulties repatriates face when they come back from international assignments. Findings suggest that these adjustment problems could lead to turnover intentions. The study also shows that work adjustment difficulties can be caused by differences between the host and the domestic organizational culture and it can be moderated by some organizational practices. Implications and recommendations for human resources practitioners and researchers are discussed.     

Expatriate stress and burnout

With rapid globalization, multinational firms are sending a growing number of employees on foreign assignments. A growing body of research attests to the interest in the stress experienced by these expatriates. The current study focused on a subject rarely addressed in expatriate stress research, namely burnout. Its goals were to demonstrate: (1) the relevance of burnout to expatriates; (2) the difference between stress and burnout; (3) the role played by the perceived importance of expatriates' work; (4) the relevance of existential theory as a theoretical backdrop. The study included 233 Israeli expatriates who responded to a questionnaire. Findings revealed high level of stress, low level of burnout and very high perceived work importance. Hierarchical regression showed that importance moderated the effect of stress on burnout. There were differences between the correlates of stress and burnout, especially work importance, which was negatively correlated with burnout and positively correlated with stress.     

International graduate students' perceptions and interest in international careers

This research developed and tested a comprehensive model of the antecedents of international graduate students' interest in an international career. Based largely on Social Cognitive Career Theory (SCCT), the model included elements that pertain to perceptions of external constraints (perceptions of the labor market, family pressure to return), international student experience (adjustment in the foreign country during graduate studies, exposure and immersion to the international context) and individual factors (self-efficacy with respect to working abroad and outcome expectancy). Participants were 139 international graduate students in the UK. Individual factors and perceived constraints were directly related to interest in an international career. The factors that comprised current international student experience were indirectly related to interest via their relationship with self-efficacy, while adjustment moderated the relationship between self-efficacy and interest. Although the hypothesized moderating role of family pressure to return did not materialize, the findings suggest that perceptions of constraints play a more substantial role in the formation of interest than has been assumed by SCCT theory thus far. The findings are discussed with respect to their implications for the literature and for the policies of host country stakeholders.
