On the basis of the Chinese schema, we propose that internal social capital manifests itself in the form of ‘guanxi’, trust, and norms. We discuss the concept of interpersonal relationships within the context of Chinese culture by embedding the guanxi concept into a model to investigate the relationships among the three dimensions. We used a survey-based methodology to collect data from 230 employees of the top 100 high-technology firms in Taiwan and structural equation modelling (SEM) with LISREL 8.54 to examine the hypotheses model. The results indicated that at the individual level, guanxi is positively related to both trust and norms, which are also positively related to knowledge sharing. The mediating effects of trust and norms were also found to be significant. Trust directly influences knowledge sharing, and plays a mediating role between knowledge sharing and guanxi. This suggests that knowledge sharing is likely to occur when trust exists among employees. The results further indicate that norms mediate the relationship between guanxi and knowledge sharing. Guanxi among members influences knowledge sharing; therefore, organizations require a feasible solution using the relational norms mechanism. Previous studies have either emphasized the direct influence of social capital or regarded all variables to be of similar importance for knowledge sharing; however, no clear explanations have been provided explaining its influence on knowledge sharing. We advance understanding of why social capital enhances knowledge sharing among employees and the means by which this occurs. 相似文献

This study set out to develop a Chinese Author Recognition Test (CART) that might be used as a measure of objective print exposure for college students in Taiwan. We found that there is a linkage between print exposure and general reading achievement for college students. We also found that, among self‐reported reading habits, comparative reading habits and CART, primary print knowledge scores within the CART family have the strongest prediction power for both the ‘General Scholastic Ability Test‐Chinese’ and the ‘Department Required Test‐Chinese’ beyond the joint contributions of vocabulary size and reading comprehension. By sharing the process of developing the instrument, we shed some light for researchers from regions other than English‐speaking countries on how they might move forward in future investigations. 相似文献

TV reporters in Taiwan often encounter accidents during regular assignment runs, which may be a significant factor that increases their intentions to leave their job. Occupational hazard has always been ignored by news media organizations. Recent research has shown that a positive organizational safety climate may improve safety-related issues. To build on previous research conducted, this study investigates the moderating effect of safety climate between safety leadership and turnover intentions. This research collected 268 valid samples with an 89% response rate. Using the hierarchical linear model, results show that the transformational leadership style is negatively related to turnover intentions and the passive leadership style is positively related. Moreover, the moderation tests found a negative relationship between the interaction of passive leadership and safety and employees' turnover intentions. This implies that when reporters are working in a positive safety climate environment, their turnover intentions will be significantly lower. On the contrary, the positive moderating effect of safety climate on the relationship between transformational leadership and turnover intention is not significant. 相似文献

The purpose of this study is to investigate the critical factors that will affect the decision to adopt cloud computing technology in developing countries, specifically in Taiwan's hospital industry. This study mainly integrates the TOE (Technology-Organization-Environment) framework and HOT-fit (Human-Organization-Technology fit) model to understand this issue. Information was collected by employing a questionnaire research design to hospital CIOs in Taiwan. The obtained results indicate that the 5 most critical factors are data security, perceived technical competence, cost, top manager support, and complexity. Further, among the proposed four dimensions the most important one is technology followed by human, organizational, and environmental factors. Finally, the results show that significant differences exist in CIO innovativeness, data security, compatibility, top manager support, adequate resource, and perceived industry pressure across different adopting groups. For practitioners, this study identifies key factors for hospitals to make an adoption decision toward cloud computing technology. As for academia, this study can be provided as a useful reference for future studies in this subject field. 相似文献
