There are many definitions of safety, but most of them are variations on the theme that safety can be measured by the number of adverse outcomes and must be enforced by using more of the same safety measures (e.g. more procedures). What the industry thinks safety is and how it can be achieved are both questionable. This article looks at six safety-related assumptions, or safety myths, which can be found across most industry practices. These myths are related to human error, procedure compliance, protection and safety, root causes, accident investigation and ‘safety first’. We argue that while relying on such myths makes safety management easier, they also make it flawed and ineffective. Therefore, we propose a critical discussion leading to a set of managerial messages. In this paper, we present the six myths in sequence and then discard them through the analysis of various industrial examples. We then replace the myths with six clearer statements in order to build an alternative view of safety. 相似文献

This Column describes a project-based, hands-on pervasive computing course offered at MIT during the fall 2001 semester. Later, I helped distill the course into an intensive one-week experience that MIT offered in spring 2002 and once again in winter 2003. Much has been carried from these three instantiations. 相似文献

Today's computers operate on the same fundamental principle as the mechanical devices dreamed up by Charles Babbage in the 19th century and later formalized by Alan Turing: one stable state of the machine represents one number. Even seemingly nonstandard computation models, such as the one based on DNA, share this basic principle. Recently, physicists and computer scientists have realized that not only do their ideas about computing rest on partly accurate principles, but they miss out on a whole class of computation. Quantum physics offers powerful methods of encoding and manipulating information that are not possible within a classical framework. The potential applications of these quantum information processing methods include provably secure key distribution for cryptography, rapid integer factoring, and quantum simulation. The authors discuss the directions that quantum information theory appears to be heading and the research and applications it has accrued 相似文献
