CV's prominence is due to its flexibility and ability to estimate total value, including passive use value. Its use and the inclusion of passive use value in benefit-cost analyses and environmental litigation are the subject of a contentious debate. This paper(More)

Understanding how people living in fire-prone areas perceive this threat is essential to the design of effective risk management policies. Drawing on the social amplification of risk framework, we develop a conceptual model of wildfire risk perceptions that incorporates(More)

This paper shows that Bergstrom's result does not generalize to the benefit-cost analysis of generic changes in public goods. There may exist good projects that will be rejected by a selfish-benefit cost test, a(More)

METHODS AND MATERIALS The Calypso System is a target positioning device that continuously monitors the location of three implanted electromagnetic(More)
PURPOSE To evaluate whether pre- and post-treatment imaging (immediately before and after a radiation therapy treatment fraction) and intermittent imaging (at intervals during a treatment fraction) are accurate predictors of prostate motion during the delivery of radiation. METHODS AND MATERIALS The Calypso 4D Localization System was used to continuously(More)
