Few answers to the question, ‘Why should I?’ seem more natural than ‘Because I want to,’ and if we are told, ‘You should do this,’ there is something natural about the objection, ‘But I don’t want to, so why?’ I believe that the very nature of normativity can be comprehensively explained in terms of desire: the myst...

Our journal—as well as science with a small " s " —went through a disappointing and troubling experience with the two stem cell papers from the South Korean research group led by Dr. Woo Suk Hwang. As a result of an investigation by a committee from, published a year later, was retracted for the same reasons. What Science did then entailed two steps. First, we compiled a chronological anthology...

In this paper the vibration behaviors of a structure equipped with a tuned liquid column damper (TLCD) under a harmonic type of earthquake loading are studied. However, due to inherent nonlinear liquid damping, it is no doubt that a great deal of computational effort is required to search the optimum parameters of the TLCD, numerically. Therefore by linearization the equation of motion of the s...

Make sure you know how to act quickly if a child ingests a toxic substance and what to teach parents to prevent accidental poisonings.

The papers in this issue of the Journal of Medical Ethics address various aspects of five familiar areas of bioethical enquiry: transplantation, genetics, euthanasia, research ethics and professional practice. That these areas, despite all that has been written about them, continue to provoke productive scholarly attention, testifies not only to their existential relevance but also to their mor...

ABSTR4CT: By using their knowledge bases, expert database systems can respond to queries that involve high level, complex concepts. However, the answers provided by these systems are composed entirely of low level facts. Recently, researchers have been developing query answering systems that include knowledge in their answers. While the specific goal and approach of each of these individual eff...
