Presents a user-oriented interface for generalized informetric analysis and demonstrates how informetric calculations can be specified through advanced data modeling techniques. Topics include bibliographic data; online information retrieval systems; citation networks; query interface; impact factors; data restructuring; and multi-level…

Investigates Web site design factors and their impact from a theoretical perspective. Presents a two-factor model that can guide Web site design and evaluation. According to the model, there are two types of design factors: hygiene and motivator. Results showed that the two-factor model provides a means for Web-user interface studies. Provides…

Considers factors that must be weighed in creating effective electronic learning environments and presents a basic framework for Web-based or electronic learning. Highlights include the institutional dimension; the pedagogical dimension; technological dimension; interface design; evaluation; management; resource support; and ethical…

Describes the MultiText information retrieval system that finds arbitrary passages of text, as opposed to complete documents, that are likely to be relevant. Discusses relevance ranking, term expansion, interactive user interface, and distributed searching used in experiments for TREC-6 (Text Retrieval Conference) in the ad hoc, high precision,…

Describes several types of user devices (computers, laptops, personal digital assistants, telephones), explaining that they serve as a translator between technology's internal representation of information and what can be perceived, processed, and used by humans. Also addresses the use of information technology devices by people with disabilities…

This study consists of two experiments. Pitch, volume, and tempo in auditory-haptic geographic information systems were compared in terms of effectiveness for multimodal interface; volume was determined to be better. Auditory display with volume and haptic display with vibration were compared and the results showed that, in more complex geographic…

The various features of a Visual Basic Program, which implements the 1672 Parr thermometer are described. The program permits remote control of the calorimetry experiment and also provides control for the flow of data and for file storage.

Those who work in libraries focus much of their energies on providing access to information, and major changes seen in the last decade have shown the need to be flexible in the ways that librarians approach content delivery. Library users span all the generations of information distribution mechanisms. Some prefer to receive information in their…

This study investigated the effect of several different modes of test administration on scores and completion times. In Experiment 1, paper-based assessment was compared to computer-based assessment. Undergraduates completed the computer-based assessment faster than the paper-based assessment, with no difference in scores. Experiment 2 assessed…

The Disabilities Information Flow (DIF) project at the University of St Andrews has sought to provide a means of efficiently managing all student disabilities information within the institution and provide appropriate role-based service interfaces for all staff who need to routinely interact with this information. This paper describes the software…

Library patrons familiar with Web searching conventions often find library searching to be less familiar and even intimidating. This article describes and evaluates a series of usability research studies employing two different and popular methodologies: user-centered redesign and usability testing. Card sorting and affinity mapping were used to…

Recent research on annotation interfaces provides provocative evidence that anchored, annotation-based discussion environments may lead to better conversations about a text. However, annotation interfaces raise complicated tradeoffs regarding screen real estate and positioning. It is argued that solving this screen real estate problem requires…

Purpose: The purpose of the paper is to evaluate the effectiveness or success of universities' portal implementation from the perspective of students as users. Adopting the model developed by Delone and McLean, portal effectiveness is defined as being composed of information quality, systems quality and service quality. In addition, the paper also…

Over the last ten years, the use of the Internet has moved from a small number of specialists to the population at large, including all ages and social groups. More recently, for those with access to computers and broadband, the Internet has become almost ubiquitous, with people using it at work, on the move, and for all sorts of leisure and…

This article describes the design and formative evaluation of a Web-based tool that supports curriculum developers in constructing competence maps. Competence maps describe final attainment levels of educational programs in terms of--interrelated--competencies. Key requirements for the competence-mapping tool were validity and practicality.…
