Reports on Phase I of a twopart project to identify and implement userbased design criteria in World Wide Web pages. The purpose of the identification phase Phase I is to identify the criteria that ...influence a particular user communitys use of the Web and to analyze these within the context of the users overall informationgathering behavior. Data were gathered through a questionnaire and electronic focus group session with nine faculty from four business schools. Participants identified 49 Web page features which clustered into eight broad categories of criteria having a significant positive or negative impact on their use of WWW pages. They also identified types of information normally used in work activities methods of finding this information within the current information service environment likely changes in behavior if the information became available via the Web, including willingness to pay.

Vergence of the eyes in the dark depends on the vertical direction of gaze. In three experiments this phenomenon was studied using eye inclinations and head tilts of 5 min duration during which ...monocular or binocular near and distant stimuli were inspected. The effects of eye inclination and head tilt on dark vergence were temporally stable; they exhibited even a tendency to increase with the passage of time. On return to horizontal gaze, positive aftereffects were found, that is dark vergence was biased towards its value with a vertically deviated gaze. The effect of vertical gaze direction turned out to be additive to the effect of binocular near fixation. These findings represent evidence against the hypothesis that the effect of vertical gaze direction on dark vergence is mediated by a feedforward signal that is related to voluntary effort in raising or depressing the eyes.
This study examines the use of Twitter in a digital library, the Internet Public Library (ipl2), to understand the content and dissemination patterns of Twitter messages posted by the ipl2. We ...conducted a content analysis on ipl2's messages on Twitter to develop a categorization of the type of tweets, and examined retweets and the active users who retweeted ipl2 tweets. We present our analysis of four areas related to the tweets: motivation, content, audience, and sources. Active users are categorized into eight groups. The research findings contribute to a further understanding of the actual use of Twitter in a digital library.
