DESCRIPTION. The Journal of Theoretical Biology is the leading forum for theoretical papers that give insight into biological processes. It covers a very wide range of topics and is of interest to biologists in many areas of research. Many of the papers make use of mathematics, and an effort is made to make the papers intelligible to biologists as a whole.(More)
BACKGROUND The Focused Assessment with Sonography for Trauma (FAST) examination has become a valuable tool in trauma resuscitation. Despite the widespread use of FAST training among traumatologists, no evidence-based guidelines exist to support optimal training requirements or to provide quantitative objective assessments of imaging capabilities. Both(More)
In this paper we attempt to unpack the meanings of " expert " and " novice " in games research. A literature review reveals unreliable definitions and inadequate operationalization of these concepts. Nonetheless, researchers default to recruiting experienced players for games research projects to the exclusion of novices. We take an interactionist approach(More)
BACKGROUND Point-of-care ultrasonography is a standard part of trauma assessments, but there are no objective tools to assess proficiency and ensure high-quality examinations. Hand motion analysis (HMA) has been validated as a measure of surgical skill but has not previously been applied to ultrasonography. HMA was assessed for construct validity in Focused(More)
In this paper we articulate an empirical approach to the study of social action in digitally-mediated contexts. Our approach extends Carl Couch's theory of cooperative action, which is based on a set of " elements of sociation " : acknowledged attentiveness, mutual responsiveness, congruent functional identities, shared focus, and social objective. Three(More)
—Cyberworlds fuel innovations in development and design, but whether and how to catalyze a slow-moving interplay among them remains an open question. This paper develops an argument for organizing interdisciplinary research through and around cyberworlds in order to bridge design and development by means of a collaboratory. To this end, it provides(More)
