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. This study was designed to investigate students¿ perceptions towards their Chinese language classroom learning environments in six areas, namely ¿Student Cohesiveness¿, ¿Teacher Support¿, ¿Involvement¿, ¿Cooperation¿, ¿Task Orientation ¿Equity¿ in Chinese Independent High Schools in Malaysia, using the Chinese Language Classroom Environment Inventory (CLCEI) developed by Chua (2004). The findings of this study are as follows: a. Except for the Involvement subscale, students perceived their classroom learning environment on the 5 subscales positively. b. 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.

This book introduces readers to environmental background investigation, pollution source intensity evaluation and risk assessment approaches used at three main types of groundwater-contaminated sites: municipal domestic waste landfills, hazardous waste landfills and oil-contaminated sites.

This book surveys the physics and fabrication of carbon nanotubes and their applications in optics, electronics, chemistry and biotechnology. The text illustrates major fabrication methods in detail, particularly the most widely used PECVD growth techniques.
