In this paper we analyse an apparently simple collaborative activity, that of passing an implement from one person to another. The particular case we consider is surgical operations where nurses and surgeons routinely pass instruments to one another. Through fine-grained analysis of specific instances we address,the preparatory work engaged in prior to passing, the ways in which the layout of a...

In architecture, design ideas are developed as much through interaction as by individuals in isolation. This awareness inspired the development of a Dynamic Architectural Memory On-line, an interactive platform to share ideas, knowledge and insights in the form of concrete building projects among designers in different contexts and at different levels of expertise. Interaction with various user...

Effects of age and training on myocardial Na+/Ca2+ exchange were examined in young sedentary (YS; 14-15 mo), aged sedentary (AS; 27-31 mo), and aged trained (AT; 8- to 11-wk treadmill run training) male Fischer Brown Norway rats. Whole heart performance and isolated cardiocyte Na+/Ca2+ exchange characteristics were measured. At the whole heart level, a small but significant slowing of late isov...
