Millions of work-related accidents occur each year around the world, leading to a large number of deaths, injuries, and a huge economic cost. Previous studies on risk assessment have revealed that it is important to calculate the probabilities of factors that can contribute to the occurrence of accidents. Several methods have been proposed to evaluate potential risk factors and to improve system safety. However, these methods have some limitations, such as their low generalizability, treating accident causation and human factor as two separate research topics, requiring intensive data, or relying solely on expert judgement. This book proposed some new ideas to address these limitations.

This book investigated the relationship between the Chinese language classroom learning environment and Grade 8 students¿ motivation to learn the Chinese language at four Chinese Independent High Schools in the Klang Valley.

Except for the student involvement subscale, female students¿ perception scores were higher than that of their male counterparts on all the other 5 subscales of the CLCEI. c. Students in general, felt good about their Chinese language classroom learning environment, and were positive about their learning environment. d. The highest correlation was observed between Motivation and the Task Orientation subscale.
