Supporting Composition in a Hypermedia Environment

This paper introduces HCOMET, a composition editor developed to facilitate writing in a hypermedia environment. HCOMET provides an environment for on-line capture and manipulation of ‘thoughts and ideas’ in a multi dimensional and multimedia manner. Composition as a mechanism for structuring and organization of information (to supplement the basic node and link model) is considered an important issue in the future generation of hypermedia systems. This paper discusses the basic issues in supporting composition, and describes the design and implementation of HCOMET. The use of HCOMET in application development is also discussed.     

Visualising historical knowledge using virtual reality technology

This paper discusses virtual reality reconstructions of historical sites. Seeing the past as a cultural construction makes the process of representation problematic. Two case studies illustrate aspects of the visualisation of virtual environments: how authenticity in computer reconstructions is reduced to their visuality, and how historically-based VR environments as copies honour their original. The paper asks for more implementation of life forms into architectural settings, and also examines the impact of user expectations on the VR experience.

The role of eye movements in the missing-letter effect revisited with the rapid serial visual presentation procedure.

When participants read a text while searching for a target letter, they are more likely to miss the target letter embedded in frequent function words than in less frequent content words. This effect is usually observed with a text displayed normally, for which it has been found that frequent function words are fixated for a smaller amount of time than less frequent content words. However, similar pattern of omissions have been observed with a rapid serial visual presentation procedure in which words appear one at a time. These parallel results would demonstrate that fixation duration per se is not the proximal cause of the missing-letter effect only if eye movements are not made during the rapid serial visual presentation procedure. Therefore, the authors performed eye monitoring during the rapid serial visual presentation procedure. Results revealed that, with a rapid serial visual presentation procedure, participants fixated function and content words for almost the entire presentation duration. It is concluded that eye movements are not the proximal cause of the missing-letter effect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Effects of trainer expressiveness, organization, and trainee goal orientation on training outcomes.

This laboratory experiment investigated the effects of trainer expressiveness, lecture organization, and trainee goal orientation on training outcomes. Participants (N?=?135) listened to lectures that differed in organization and trainer expressiveness. Participants completed recall and problem-solving tests immediately and 2 days later. The results indicated that participants had the highest recall after an expressive and organized lecture. The findings for problem-solving performance were more complex. Participants with a high mastery orientation had their poorest problem-solving performance after listening to an organized and inexpressive lecture, whereas participants with a low mastery orientation did not respond to the effects of organization or expressiveness.

A method for measuring work interference in surgical teams

To enhance surgical systems we need to manage the performance of the teams that comprise them. To do this we must measure the properties and processes of teams and account for the demands and conditions of their work. Recent research shows that observation is a potentially valuable method of measurement, but its potential application in surgery remains unclear. In this study of laparoscopic cholecystectomy, an observer applied observational measures of teamwork in the operating theatre and recorded intra-operative interference from observed distraction and interruption. Results showed that it was feasible to observe a broad scope of teamwork and to reveal the frequency and source of work interference. However, the measures were necessarily selective and so limited in their analysis of the conditions and events that might interfere with the collective work in surgery. Such measures may however prove useful when applied in conjunction with other methods of measurement and utilised as performance feedback data.
