YU, ZHANG. An Empirical Assessment of the Role of Driver Motivation and Emotion State, and Driving Conditions in Perceived Safety Margins. (Under the direction of Dr. David B. Kaber). Models of motivation in driver behavior have been developed to predict driver performance under different conditions. Among existing models, Näätänen and Summala’s multi-dimensional threshold model (1976) was sele...

OBJECTIVE The ability of occupational health and safety (OHS) legislation and regulatory enforcement to prevent workplace injuries and illnesses is contingent on political, economic, and organizational conditions. This systematic review of qualitative research articles considers how OHS legislation and regulatory enforcement are planned and implemented. METHODS A comprehensive search of peer-...

In this paper we focus on formal concepts for an integrated modeling of complex systems. We take our examples from the field of sociotechnical systems where we state a great need for model-based reasoning regarding questions of system safety and the definition of long-term management policies. We lay our special focus on systemic capabilities related to context adaptive behavior with special co...

Fault-tree analysis is applied to technological systems to determine the probability of system’s failure modes with unacceptable consequences, called “critical states”. As many Fault-trees as the number of system’s critical states are constructed and analysed; when their probabilities are deemed not acceptable, the Importance and Sensitivity Analysis (ISA) is applied to improve the system safet...

It was hypothesized that occupational health and safety (OHS) inspectors who prefer to use autonomy supportive tactics to resolve workplace conflicts (e.g. providing rationale, choices) would be more effective in resolving industry non-compliance with OHS regulations, compared to inspectors who prefer to use coercive tactics (e.g. deadlines, pressure). Preferences for resolving work conflicts w...

BACKGROUND Safety programs are a core part of safety management in workplaces that can reduce incidents and injuries. The aim of this study was to investigate the influence of Safety Training Observation Program (STOP) technique as a behavior modification program on safety climate in a construction company. METHODS This cross-sectional study was carried out on workers of the Petrochemical Con...
