Managing the health and wellness of occupational drivers requires the recognition of burnout as an occupational hazard. However, the literature is dominated by studies of stress rather than burnout. The manner in which burnout may affect accident involvement is investigated in occupational drivers. The proposed causal structure is based on the stressor strain model, in which burnout mediates between occupational stress and accident involvement. The study recruited 915 public transport drivers. The Copenhagen Burnout Inventory and an effort reward imbalance scale were adopted to measure burnout and occupational stress, respectively. Results of the analysis indicated that burnout exerted a direct effect on accident involvement beyond the effect of occupational stress. Enhancing the perception of a safety culture does not significantly reduce the effect of occupational stress on burnout; however, it does significantly reduce the effect of burnout on accident involvement and thus indirectly alleviates the effect of occupational stress on accident involvement. In summary, as a comprehensive measure of the adverse effect of various types of chronic stressors, burnout provides a strong indicator for the identification of drivers who pose a risk to the organization and to road safety. Burnout management should be incorporated into overall stress management. Occupational drivers normally experience a low level of empowerment and long work hours; thus, a safety culture is crucial to this occupational category to reduce burnout and ensure workplace safety.

This study investigated how the different discussion approaches in Facebook influenced students\' scientific knowledge acquisition and the nature of science (NOS) views. Two eighth-and two ninth-grade classes in a Taiwanese junior high school participated in the study. In two of the classes students engaged in synchronous discussion, and in the other two classes they engaged in asynchronous discussion. The 83 participating students discussed scientific news that had been posted on Facebook, with a total of seven news stories. Three instruments - a general NOS views questionnaire, a content-related NOS views questionnaire, and a science knowledge test-were administered before, immediately after, and three weeks after the intervention. In addition, student responses to each news story were collected and analyzed. The results demonstrated that regardless of which online discussion group they participated in, students improved their science content knowledge, general NOS views, and NOS analyses of scientific news. Especially, synchronous discussion proved more effective than asynchronous discussion at helping students to develop science content knowledge and increase their view of community aspects of content-related NOS. These findings demonstrated the advantages of quick feedback and responses in synchronous discussion facilitated communication and cognitive development about subject and subject-related nature of science.

Stress is the primary cause of strain and health problems for occupational drivers whose jobs directly relate to public safety. Although several stress theories and scales have been proposed, the method of adequately measuring the stress of occupational drivers remains unclear. We investigated the reliability and validity of the effort-reward imbalance (ERI) model and the generic 23-item ERI scale and its association to strain and health problems in occupational drivers. A total of 927 Taiwanese public transport drivers were recruited. Parallel confirmatory factor analyses (CFAs) were applied to evaluate the validity of the ERI components. Their association with burnout levels, cardiovascular disease (CVD) symptoms, and self-rated health was examined using regression methods. The CFA results showed satisfactory psychometric properties of the ER! components. Physical demands, overtime, and stress-induced sleep problems were the primary stressors in occupational drivers. The regression results showed that an imbalance between effort and reward and overcommitment levels were strong and independent predictors of strain and health outcomes. We extend the application of the ERI model to measure the stress of Taiwanese public transport drivers; its correlation with strain and health outcomes shows that the ERI scale is a reliable tool for identifying strained or unhealthy drivers.
