This study examined the relationship between safety climate and organizational citizenship behaviors (OCB). It involved a comparative analysis between workers active in citizenship behaviors and their colleagues who were passive or inactive regarding OCBs. Additional analyses also compared
job satisfaction, compliance with safe work policies, and accident frequency between the two groups. T-tests were used in these comparative analyses. A positive association was found between safety perception and OCBs: workers who actively engaged in citizenship behaviors had positive
perceptions of safety in their workplaces, and vice versa. Additionally, the group active in OCBs expressed more job satisfaction, were more compliant with safety management policies, and subsequently had a relatively lower accident involvement rate. The implications of these findings in the
work environment are discussed.

This study examined to what extent nuclear risk perceptions, organizational commitment (OC), and appraisals of management are associated with each other among nuclear power plant personnel. The sample consisted of 428 nuclear power plant workers who completed a questionnaire at their workplace. Perceived nuclear risk and OC were most closely related to the appraisals of the top management of the organization. As the trust in and satisfaction with the top management increased, perceived nuclear safety and acceptance of the organizational goals and values heightened. This result is discussed in the context of industrial safety management.

The aim of this study was to examine the effects of genetic and environment influences and sex on injury involvement using two sets of Finnish twin data. The younger participants were 955 twins born between 1983 and 1987, aged 20 to 24 years. The older participants were 12,428 twins born between 1930 and 1957, aged 33 to 60 years. Within-twin correlations in monozygotic and dizygotic twins suggested that genetic effects play no role in injury involvement among young twins, but do have some effect at older ages. The results indicated that environmental factors have greater importance in injury involvement than genetic factors in the younger twin data set (FT12), whereas in a middle-aged (33–60 years) twin data set, genetic effects explained about quarter of the variance in injury involvement. Sex was a strong contributing factor, with males being generally more prone to injuries than females.
