A suggestion that protective eye gear can pose a threat either to the crystalline lens or to the retina is examined from an epidemiological point of view. It is concluded that it may accentuate a pre-existing high-risk hazard but has little significance for low-risk hazards.

We describe a framework for relating available data on hazards to impact on infrastructure. It is designed to be used by simulation platforms that may focus on a single infrastructure layer or aim to study interactions between interdependent layers. The Hazard Impact Framework (HIF) provides a flexible scheme for capturing and maintaining data on the response of elements of critical infrastruct...

To predict the outcome of (almost) any experiment we have to assume that our spacetime is globally hyperbolic. The wormholes, if they exist, cast doubt on the validity of this assumption. At the same time, no evidence has been found so far (either observational, or theoretical) that the possibility of their existence can be safely neglected.

Natural hazard research began as a study of cultural perceptions to extreme naturally occurring events. Since the advent of the study, natural hazard literature has become steeped in terminology that is sometimes confusing to the reader. The concepts of hazard, risk, and disaster are often confused with one another and with the extreme event itself. Although the extreme event is inherent in haz...

This paper discusses an experiment that measured the effectiveness of a hazard identification process used to support safety in Defence Standard 00-56 project. The experimental case study utilised a Ministry of Defence project that assessed simultaneously two potential suppliers who were competing for a MOD equipment contract. The UK MOD Corporate Research Programme funded the comparison work a...

The United States has no comprehensive national warning strategy that covers all hazards in all places. Instead, public warning practices are decentralized across different governments and the private sector. Uneven preparedness to issue warnings exists across local communities; hence, people are unevenly protected from the surprise onset of natural disasters. Without changes in this situation,...

Improving the Presage Polymer Radiosensitivity for Hot Cell and Glovebox 3D Characterization Adamovics, John; Farfan, Eduardo B.; Coleman, J. Rusty Health Physics (2013), 104(1), 63-67. RadBall is a novel, passive, radiation detection device that provides 3D mapping of radiation from areas where measurements have not been possible previously due to lack of access or extremely high radiation dos...

We consider a principal-agent model with moral hazard where the agent’s knowledge about the performance measure is ambiguous and he is averse towards ambiguity. We show that the principal may optimally provide no incentives or contract only on a subset of all informative performance measures. That is, the Informativeness Principle does not hold in our model. These results stand in stark contras...
