While much has been written about caregiving stress, little has been written regarding the ethical dimensions of filial responsibility and daughter and son caregivers' perceptions of responsibility and moral demands. This paper will address the concept of f...

With new laser techniques and with gas phase and molecular beam experiments, it is now possible to determine the ultrafast motion in isolated chemical reactions-chemistry on the I 0 l 3 -second time scale. A decade ago this magazine devoted a special issue to laser chemistry (see PHYSICS TODAY, November 1980). One of the articles emphasized the importance of time scales in chemical reactions an...

The number of fatal accidents involving public transport aircraft has increased significantly in recent years and, because more and more "wide-bodied" aircraft have been coming into service, this has resulted in a rapid increase in the number of fatalities. A combined attack on the problem by all concerned with flight safety is required to improve the situation. The collection and analysis of a...
