Challenging Safety Regulation – a Wake-up Call
نویسندگان
چکیده
In presenting a framework for tackling these issues, the paper examines current safety practices. In particular it challenges, from a theoretical perspective, and by reference to recent research, two common misconceptions that safety is largely a matter of equipment reliability and that process-based assurance can provide adequate evidence of system safety. It argues that failure to address these two weaknesses can lead to, wasted effort, inadequate safety assurance and, at worst, unsafe systems.

WAKE-UP CALL FOR CREEP, MYTH ABOUT SIZE EFFECT AND BLACK HOLES IN SAFETY: WHAT TO IMPROVE IN fib MODEL CODE DRAFT
Although the 2010 Draft of fib Model Code is overall an excellent document, it has some weaknesses which could, and should, be corrected. One is the material model for creep and shrinkage prediction, which not only is theoretically obsolete but also is indefensible in view of the wake-up call provided by recently collected long-term deflections of 56 bridges. The second is a size effect formula...

Endogenous circadian rhythms exert strong effects on sleep, but the neuronal mechanisms that produce these effects have remained obscure. New work implicates neuropeptidergic signaling in a subset of circadian clock cells in the regulation of sleep late at night.

We test whether the sharp increase in sovereign spreads of euro-area countries with respect to Germany after the explosion of the Greek crisis was due to deteriorating macroeconomic and fiscal fundamentals or to some form of financial contagion. Our analysis includes indicators of domestic and external imbalances which were mostly disregarded by previous studies, and distinguishes between inves...
متن کاملSubconscious Stimulus Recognition and Processing During Sleep
During sleep, consciousness is reduced, associated with a diminished connection of the brain to the environment. This is due to the blocking of the thalamocortical pathway by inhibitory mechanisms. This “thalamic gating” during sleep, however, is not complete, but partial. The stream of information is considerably reduced, but the brain is not fully disconnected from the environment. An inspect...
