Safety behavior of construction workers is crucial to safety outcomes, and such behavior can be affected by different ways of risk perception. This research first identifies four main ways of risk perception: risk consequence, risk probability, risk utility, and direct risk perception, and then examines whether they are distinct. Further, the effects of these distinct risk perception ways on workers'...
As one of the most important participants in construction industry, construction workers' unsafe behavior is very common on construction sites. From an individual level, this research aims to investigate the relationship among risk perception, risk propensity and unsafe behavior decision-making. A survey is conducted within first-line workers in Chinese construction projects. The results show that:...
Construction workers' Workplace Deviant Behavior(WDB) has significant impact on project success. However, existing researches on its occurrence mechanism are mainly focused on personal and organizational factors. Psychological ownership, which has been proved to be a critical variable affecting behavior decision making, has not been considered in the occurrence of construction workers' WDB. This paper...
Purkinje fiber network (PFN), one of the most important components of the ventricular conduction system, is crucial in modeling ventricular tachycardia and fibrillation. Construction of anatomical detail Purkinje fiber network, however, is a very challenging task. In this paper, we present a novel method for restoring the 3D PFN in the left ventricle (LV) by manifold learning. Motivated by the fact...
