Duncan Pritchard (et al. 2010, 2012a, 2012b) has recently shifted his view from an account that primarily understands knowledge in terms of the safety principle (a view mainly developed in his 2005 monograph on epistemic luck) to an ‘impure’ variety of virtue epistemology, which combines the safety principle with a weakened virtue-theoretic condition, a view that he calls anti-luck virtue epist...

BACKGROUND There can be little doubt that the construction is the most hazardous industry in the worldwide. This study was designed to modeling the factors affecting unsafe behavior from the perspective of safety supervisors. METHODS The qualitative research was conducted to extract a conceptual model. A structural model was then developed based on a questionnaire survey (n=266) by two stage ...

BACKGROUND Exposures to occupational hazards substantially increase workers' risk of developing musculoskeletal disorders (MSDs) and can exacerbate pre-existing disorders. The effects on MSD risk of the physical requirements of work performance are well recognised, but there is now ample evidence that work-related psychosocial hazards can also have substantial effects; further, some hazards may...

This paper is concerned with a diffusion model of phase-field type, consisting of a parabolic system of two partial differential equations, interpreted as balances of microforces and microenergy, for two unknowns: the problem’s order parameter ρ and the chemical potential μ; each equation includes a viscosity term – respectively, ε ∂tμ and δ ∂tρ – with ε and δ two positive parameters; the field...

Decision makers working to improve transportation systems must constantly balance the need to improve roadway safety through infrastructure investment with constraints of available resources. We have explored the additional information available to transportation decision makers by integrating two independent datasets, traffic accident and roadway pavement condition data. The roadway condition ...
