Power spectral and bispectral study of factors affecting employee turnover

Abstract

Voluntary employee turnover can cause organ­izations to lose profits and competitiveness. Unexpected employee turnover may also result in project delay and reduction in project quality. It is important to control employee turnover rate and maintain good employees within an organization. This paper investigates the major causes of voluntary employee turnover in engineer­ing industries. Australia, Mainland China, and Taiwan were selected for the investigation. Questionnaires were administered, and structured interviews were conducted. Power spectrum was used for the analysis. It was found that “Good physical working environment”, “Receiving advanced training”, and “Short travel distance between home and work” are the major job-related ideal factors for the Australian, Mainland China, and Taiwan respondents, respectively. However, “Far distance between work and home” and “Dislike the colleague relationships” are found as the major factors for leaving jobs for the Australian/ Taiwan and Mainland China respondents, respectively. Recommendations to improve and to control employee turnover rate are also discussed.

Evaluation of workplace safety performance in the Chinese petroleum industry

Abstract

Reform of the Chinese petroleum industry has entered its second phase since early 1999. The productiv­ity of the petroleum industry has been greatly improved, while the safety performance and records are not satisfac­tory. This paper investigates the critical factors for improv­ing safety performance in the Chinese petroleum industry. The data used for the analysis are from a questionnaire survey administered to 480 professionals in the petroleum industry in which 143 valid responses were received. Sta­tistical analysis techniques are used to analyze the data collected. The findings revealed that the most significant source of the safety problem is due to the combination of several reasons, including (a) violation on operating pro­cedures, (b) obsolete facilities and equipment failures, (c) insufficient safety management system, (d) improper commands, number of casualties, and (e) production per­formances and operating skills. The three most essential protective methods include safety training and increasing staff’s safety consciousness, cultivating safety culture, and enhancing equipment management and detecting hazards in time.
