The purpose of this study is to identify the best model that explains the relationship between conflicting risk structures and decision quality. Using confirmatory factor analysis and hierarchical regression techniques as statistical methods, the author confirmed that changes in the conflicting risk structures correlated with changes in decision…

An examination of research on expertise reveals potential gaps in current conceptualizations. Examinations of expertise often involve problems in ill-structured domains, which require abstract problem solving. Thus, conceptualizations of expertise are characterized by the use of relatively advanced, abstract problem-solving skills. Problems in…
