大学生完美主义与网瘾

采用问卷调查法对853名按分层抽样原则所抽取的大学生被试进行调查,测量工具分别为中文网络成瘾量表(CIAS)与大学生完美主义问卷(PSCCS)。数据分析的结果表明:(1)完美主义人格是大学生网瘾的重要预测因子,尤其网瘾的强迫性上网与网瘾所致的人际关系健康指标受其影响最大;(2)其非适应性成分担心出错与父母期望对网瘾具有显著的正向预测作用,而适应性成分条件性对网瘾具有显著的负向预测作用;(3)完美主义适应性成分个人标准对大学生网瘾并无实质性影响。     

ICTs and Internet adoption in China's tourism industry

The fast development of information communication technologies (ICTs) and the expansion of the Internet have changed industry structures around the world. New technologies have been adopted in the tourism industry in Europe and America for more than 30 years, and the trend is likely to continue into the future. China, as a fast-growing developing country in Asia, is gaining importance in the international tourism market for its historical and cultural attractiveness as a destination. It is also becoming a booming tourism source country as its population starts travelling overseas. This study examines how the ICT and Internet gradually change the tourism industry structure in China; how important such changes are, and to where such changes will lead China's tourism industry. This exploratory research is conducted based on information collected from several tourism organisations, such as airlines, hotels, tour operators, visitor attractions and the tourism authorities within China.     

Do instant messaging interruptions help or hinder knowledge workers’ task performance?

The modern workplace environment is filled with interruptions due to the necessity of coworkers to communicate with each other. Studies have revealed that interruptions can impact task performance (TP). Communication interruptions are due, in part, to the unavoidable side-effect of using technology to facilitate these interactions. This experimental case study reports about an investigation we conducted on the role of instant messaging interruptions (IMI) and its implications on knowledge workers’ TP in a workplace environment. We have gathered data from knowledge workers engaged in an e-learning activity. The case study included a total of 60 experimental observations and analysis of the 120 records revealed that the time to complete a task (TPtct) for certain types of tasks, was significantly affected by IMI. This case study addressed gaps in IM interruption research and practical knowledge about the role of instant messages in the organization. Previous research has been conducted in a laboratory environment with interruptions generated by means other than actual IM. This case study used IMI with participants working in their normal workplace. Findings were used to provide a set of lessons learned recommendations for managers when it comes to the use of IM in the workplace.     

Leveraging social grouping for trust building in foreign electronic commerce firms: An exploratory study

Internet development has fueled e-commerce firms’ globalization efforts, but many have met with only limited success. This often stems from the foreign firms’ limited understanding of a focal country's local culture and idiosyncrasies. Foreign firms are usually viewed as out-group entities, which lowers consumers’ trust in them. The extent of such a phenomenon varies. In locations where people are more skeptical of out-groups, a critical question is whether it is possible to transform such foreign out-group firms into in-groups, specifically with the support of popular social networking media. Based on Social Identity Theory and Trust Transference Process, five strategies leveraging social grouping and social ties to build trust for foreign electronic commerce firms were proposed. A survey was conducted to examine their effectiveness. The results suggest that social-grouping strategies are useful for in-grouping foreign out-group entities to build trust, and the effectiveness of strategies is determined by the social similarity and psychological distance between the consumer and the endorser. This has important implications for scholars and practitioners, both local and abroad, to leverage social grouping to boost Internet sales.
