This paper discusses an approach for treating model uncertainties in relation to quantitative risk assessments. The analysis is based on a conceptual framework where a distinction is made between model error–the difference between the model prediction and the true future quantity–and model output uncertainty–the (epistemic) uncertainty about the magnitude of this error. The aim of the paper is ...

Over eighty percent of pregnant women in the United States are prescribed at least one drug during pregnancy. The U.S. Food and Drug Administration (FDA) regulates the labeling of drug products and has established five risk categories for drug use during pregnancy. This classification was introduced in 1979.

This paper describes a case study addressing risk assessment in a hospital unit. The objective was to analyse the impact on collaborative work after the unit changed their installations. The study adopted the SHELL model. A tool aiming to support the inquiring activities was also developed. The outcomes of this research show the model is adequate to analyze the complex issues raised by healthca...

Sharing knowledge of Physicians within hospitals can realize potential gains enormously and is critical to be successful and survive in competitive environments. There is a need for empirical research to identify the factors that determine physician's behavior to share knowledge. This study investigates the factors that determine the physician's individual knowledge sharing behavior in his/her ...
