Most previous studies concerning company performance evaluation focus merely on operational efficiency. Operational effectiveness, however, which might directly influence the survival of a company, is usually ignored. As a result, this paper presents a study which uses an innovative two-stage data envelopment analysis model that separates efficiency and effectiveness to evaluate the performance of 41 listed corporations of the banking industry in Taiwan. The empirical result of this paper is that a company with better efficiency does not always mean that it has better effectiveness. There is no apparent correlation between these two indicators.

Most domestic online games are foreign games authorised for distribution in Taiwan. Thus, domestic distributors do not have the right to change the design of games. All that they can do is provide sufficient support and improve service quality, system quality (SQ), and information content to online game players. Many empirical studies have pointed to the technology acceptance model (TAM) to explain whether users accept a new information technology. Therefore, this study adopted TAM to investigate external factors that affect gamer acceptance of online games and used SQ, information quality, and service-provider characteristics (SPCs) as external variables. In the aspect of perceptions, SQ was found to have positive effects on perceived ease of use and perceived usefulness. SPCs had positive effects on perceived usefulness and perceived trust. The research finding in the relationship between user perception and attitude and intention was consistent with the TAM suggestion; i.e. perceived ease of use had positive effects on perceived usefulness and user attitude, and perceived usefulness had positive effect on user attitude. Finally, user perceived trust and attitude positively correlated with user intention of use.

This research reviews the constructs and measurements of guanxi and concludes that colleague guanxi is appropriately conceptualized as a multidimensional construct that describes Chinese colleague relationships. The development of a colleague guanxi scale with four dimensions is described. Two studies test the convergent, discriminant, and nomological validity of the guanxi scale. In validation tests guanxi intensity increases with cognition features (subjective fit and cognitive trust) and results in a positive affect (affective trust). Contributions of the colleague guanxi scale are offered.
