Researchers have found that high-performance human resource practices (HPHRP) are positively related to good firm performance and sustainable competitive advantage; however, there is not substantial evidence about their effect on individual creativity. We examined the relationship between HPHRP and individual creativity with a sample of 466 employees of high-tech industries in China. Findings showed that HPHRP had an inverse U-shaped relationship with individual creativity, which was positively moderated by proactive personality. When the employee had a very proactive personality, the positive relationship between human resource practices that were not high performance and individual creativity, and the negative relationship between HPHRP and individual creativity escalated. Evidence also supported a mediation effect of intrinsic motivation on the interaction effect of HPHRP, proactive personality, and individual creativity.

Air brake systems have been widely used in heavy trucks and intercity buses for its great superiority over other brake system. In traditional, many researchers focused on the vehicle dynamics which employ the static characteristic of brake system to analysis the vehicle brake capacity. In fact, the practical performance of air brake system may be greatly different from the static theory. Thus, it is necessary to build an integrate air brake system model to simulate the process of brake accurately. Also, some works focused on the dynamic characteristics of brake system have been completed, but it is not comprehensive without the considering the effect of vehicle dynamics. In this paper, a completely air brake system dynamic model is built, where the air brake system contains pneumatic subsystem and mechanical subsystem. The air brake system is embedded in a heavy truck dynamic model which contains three axles. The simulation results show the brake distance, vehicle velocity, vehicle deceleration, and brake torque for each wheel in the process of brake.
