Public access to cultural heritage collections is a challenging and ongoing research issue, not least due to the range of different reasons a user may want to access materials. For example, for a virtual museum website users may vary from professionals or experts, to interested members of the public visiting on a whim. In this paper, we are interested in… (More)

There are many factors in task design that might make it 'complex': having multiple components, having multiple cross-dependent components, tasks that involve comparison, evaluation, estimation, or learning. In this paper, we discuss a case study of a complex task we may consider to be highly natural, a common concern for many people, and one that 'should'… (More)

This paper investigates techniques used by children in year 4 (age eight to nine) of a UK primary school to reformulate their queries, and how they use information retrieval systems to support query reformulation. Method. An indepth study analysing the interactions of twelve children carrying out search tasks in a primary school lesson;… (More)
Children's search behavior has mainly been studied in single search sessions where the search task is new to the children. In this proposal it is suggested that an investigation into children's search on a single topic across multiple search sessions may reveal different search behaviour to what is already known.
Significant correlations between prebedtime activities and sleep satisfaction varied with sleep length in 115 college students: 15 short sleepers who listened to music were less satisfied with sleep, while 18 long sleepers who snacked on milk and sweets were more satisfied with sleep. Longer sleepers may substitute alcohol for food as they grow older.
