Food Safety Risk Analysis: A Global Issue

In the past, control of human health hazards in fresh food of animal origin has generally depended on traditional principles of hygiene, with few attempts to draw quantitative associations between hygiene activities and their outcomes in terms of human health. However, “modernization” of food hygiene programs for fresh foods of animal origin is now a commercial and regulatory goal in a number o...

Aquatic selenium pollution is a global environmental safety issue.

Selenium pollution is a worldwide phenomenon and is associated with a broad spectrum of human activities, ranging from the most basic agricultural practices to the most high-tech industrial processes. Consequently, selenium contamination of aquatic habitats can take place in urban, suburban, and rural settings alike--from mountains to plains, from deserts to rainforests, and from the Arctic to ...

Temporary Safety Hazards

The Epistemic Objection says that certain theories of time (like the “growing block” and “moving spotlight”) imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in t...

Specifying Safety-Related Hazards Formally

We show how safety analysis can guide the formal development of controlling software of a safety-critical system. The system is specified in action system framework. The framework is based on a firm mathematical foundation within which the reasoning about the correctness and behavior of the system under development is carried out. We encode information about the identified hazards and their lev...
