Influence of demographics on risky driving behaviour among powered two wheeler riders in Kerala, India

Abstract: This study is designed to explore the statistical significance of the demographic variables with respect to six risky driving behaviour variables, i.e., drunken drive (DD), helmet usage (HU), cell phone usage (CU), family involvement (FI), commitment to safety (CS) and negligence of vehicle examination (NE), which influence risky driving behaviour of Powered Two Wheeler (PTW) riders. A questionnaire survey is conducted among the PTW riders from all districts of Kerala State. The results show that, male riders are significantly more involved in drunken driving and cell phone usage, while female riders are significantly more inclined to helmet usage and family involvement. The age of the rider shows significant difference on cell phone usage. The educational level of the rider exhibit significant difference on all six variables. The riders educated up to degree and above degree level are found to be more inclined to helmet usage, while drunken driving, cell phone usage and negligence of vehicle examination are found appreciably low among them compared to riders educated up to Grade 10 and Grade 12. Results of this study can be used to conduct appraisal and counselling programme about the unsafe and risky driving acts, resulting from drunken drive, helmet non usage, cell phone usage while driving and negligence of PTW examination among the male and young riders educated up to 12 Grade.

Out of the Crisis

Abstract: According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Safety climate and injuries: an examination of theoretical and empirical relationships.

Abstract: Our purpose in this study was to meta-analytically address several theoretical and empirical issues regarding the relationships between safety climate and injuries First, we distinguished between extant safety climate-->injury and injury-->safety climate relationships for both organizational and psychological safety climates Second, we examined several potential moderators of these relationships Meta-analyses revealed that injuries were more predictive of organizational safety climate than safety climate was predictive of injuries Additionally, the injury-->safety climate relationship was stronger for organizational climate than for psychological climate Moderator analyses revealed that the degree of content contamination in safety climate measures inflated effects, whereas measurement deficiency attenuated effects Additionally, moderator analyses showed that as the time period over which injuries were assessed lengthened, the safety climate-->injury relationship was attenuated Supplemental meta-analyses of specific safety climate dimensions also revealed that perceived management commitment to safety is the most robust predictor of occupational injuries Contrary to expectations, the operationalization of injuries did not meaningfully moderate safety climate-injury relationships Implications and recommendations for future research and practice are discussed

Risk analysis and assessment methodologies in the work sites: On a review, classification and comparative study of the scientific literature of the period 2000–2009

Abstract: The objective of this work is to determine and study, analyze and elaborate, classify and categorize the main risk analysis and risk-assessment methods and techniques by reviewing the scientific literature. The paper consists of two parts: a) the investigation, presentation and elaboration of the main risk-assessment methodologies and b) the statistical analysis, classification, and comparative study of the corresponding scientific papers published by six representative scientific journals of Elsevier B.V. covering the decade 2000–2009. The scientific literature reviewing showed that the risk analysis and assessment techniques are classified into three main categories: (a) the qualitative, (b) the quantitative, and (c) the hybrid techniques (qualitative–quantitative, semi-quantitative). The qualitative techniques are based both on analytical estimation processes, and on the safety managers–engineers ability. According to quantitative techniques, the risk can be considered as a quantity, which can be estimated and expressed by a mathematical relation, under the help of real accidents’ data recorded in a work site. The hybrid techniques, present a great complexity due to their ad hoc character that prevents a wide spreading. The statistical analysis shows that the quantitative methods present the highest relative frequency (65.63%) while the qualitative a lower one (27.68%). Furthermore the hybrid methods remain constantly at a very low level (6.70%) during the entire processing period.
