    Abstract
    We present the first systematic study of the influence of time on user judgements for rankings and relevance grades of web search engine results. The goal of this study is to evaluate the change in user assessment of search results and explore how users' judgements change. To this end, we conducted a large-scale user study with 86 participants who evaluated 2 different queries and 4 diverse result sets twice with an interval of 2 months. To analyze the results we investigate whether 2 types of patterns of user behavior from the theory of categorical thinking hold for the case of evaluation of search results: (a) coarseness and (b) locality. To quantify these patterns we devised 2 new measures of change in user judgements and distinguish between local (when users swap between close ranks and relevance values) and nonlocal changes. Two types of judgements were considered in this study: (a) relevance on a 4-point scale, and (b) ranking on a 10-point scale without ties. We found that users tend to change their judgements of the results over time in about 50% of cases for relevance and in 85% of cases for ranking. However, the majority of these changes were local.

    Abstract
    Apart from information retrieval there is virtually no other area of information science that has occasioned as much resarch effort and writing as 'user studies'. Within user studies the investigation of 'information needs' has been the subject of much debate and no little confusion. The aim of this paper is to attempt to reduce this confusion by devoting attention to the definition of some concepts and by proposing the basis for a theory of the motivations for information-seeking behaviour

    Abstract
    This study presents a test of the Anxiety-Expectation Mediation (AEM) model of library anxiety. The AEM model contains variables that are directly or indirectly related to information search performance, as measured by students' scores an their research proposals. This model posits that library anxiety and self-perception serve as factors that mediate the relationship between performance in writing a research proposal and other cognitive, personality, and demographic variables. The model was tested using 225 graduate students enrolled in several sections of an introductory-level course at a midsouthern university. Structural equation modeling techniques supported the AEM model. In particular, library anxiety and research achievement were reciprocally related. Furthermore, library anxiety mediated the relationship between research performance and the following variables: age, grade point average, learning style, academic procrastination, and self-perception. The path analysis also revealed a direct, positive path from self-perception to research performance. In addition, self-perception moderated the relationship between research achievement and academic procrastination, perfectionism, and hope. The AEM model of library anxiety suggests that Wine's (1980) Cognitive-Attentional-Interference theory, Onwuegbuzie, Jiao, and Bostick's (in press) ILP model of library anxiety, and Bandura's (1977) self-efficacy theory can be applied to the library and information context. Findings are discussed within the framework of current social-psychological models of educational achievement.

    Abstract
    The project proposes and tests a comprehensive and systematic model of user evaluation of Web search engines. The project contains two parts. Part I describes the background and the model including a set of criteria and measures, and a method for implementation. It includes a literature review for two periods. The early period (1995-1996) portrays the settings for developing the model and the later period (1997-2000) places two applications of the model among contemporary evaluation work. Part II presents one of the applications that investigated the evaluation of four major search engines by 36 undergraduates from three academic disciplines. It reports results from statistical analyses of quantitative data for the entire sample and among disciplines, and content analysis of verbal data containing users' reasons for satisfaction. The proposed model aims to provide systematic feedback to engine developers or service providers for system improvement and to generate useful insight for system design and tool choice. The model can be applied to evaluating other compatible information retrieval systems or information retrieval (IR) techniques. It intends to contribute to developing a theory of relevance that goes beyond topicality to include value and usefulness for designing user-oriented information retrieval systems.

    Abstract
    This qualitative investigation is situated in the field of information seeking and use, and decision-making theory provided a framework for the study. In a naturalistic setting and across a range of curriculum areas, it investigated the behavior of secondary school students undertaking information search tasks. Research questions focused on students' criteria for assessing the relevance and reliability of information. Thirty-seven students between 14 and 17 years of age from a southeastern Australian school participated. The study collected data from journals; interviews, including video-stimulated recall interviews; think-aloud reports; video screen captures; and questionnaires. Data analysis culminated in grounded theory. Initial judgments of an item's relevance were based on comprehensibility, completeness of source, whether the item needed to be purchased, whether video sources were suitable, and whether factual or opinionative material met students' needs. Participants preferred information that provided topic overviews, information that linked to prior knowledge, and sources that treated topics in acceptable depth and were structured to facilitate accessibility. Students derived clues about reliability from URLs and considered the reputation of sources. The ability of an item to corroborate prior knowledge, its graphic design, its style of writing, and the perceived authority of its creators influenced participants' decisions about reliability.

    Abstract
    W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users

    Abstract
    An underlying basic assumption in contemporary information retrieval research is that the process of inquiry is driven by conscious cognition, while the role of unconscious cognition has been largely assumed not to exist or has been unacknowledged. Consequently, information retrieval theory has been unable to explain why inquirere tend to represent their problems so poorly, particularly at the outset. Reports results of a study of the elicitation of unconscious cognition in the course of an in depth inquiry, using an information counselling approach with the aid of a programmed relaxation device (audiovisual integrator) and a EEG computeroied biofeedback monitoring device. The experiment was conducted on 36 graduate students and faculty members randomly assigned to an experimental and a control group. The experimental group showed marked increases in intuition, insight, ideas and conceptual fluidity. The mobilization of unconscious cognition also has a positive impacts on the formulation and representation of research problems for the inquirer and the intermediary

    Abstract
    Purpose - Apart from information retrieval there is virtually no other area of information science that has occasioned as much research effort and writing as "user studies". Within user studies the investigation of "information needs" has been the subject of much debate and no little confusion. The aim of this paper is to attempt to reduce this confusion by devoting attention to the definition of some concepts and by proposing the basis for a theory of the motivations for information-seeking behaviour. Design/methodology/approach - The paper describes the issues of user studies and information needs within the context of information science. Findings - The paper finds that the problem seems to lie, not so much with the lack of a single definition, as with a failure to use a definition appropriate to the level, and purpose of the investigation. Originality/value - The analysis may be used as a springboard to research based upon a wider, holistic view of the information user.

    Abstract
    Multitasking is the human ability to handle the demands of multiple tasks. Multitasking behavior involves the ordering of multiple tasks and switching between tasks. People often multitask when using information retrieval (IR) technologies as they seek information on more than one information problem over single or multiple search episodes. However, limited studies have examined how people order their information problems, especially during their Web search engine interaction. The aim of our exploratory study was to investigate assigned information problem ordering by forty (40) study participants engaged in Web search. Findings suggest that assigned information problem ordering was influenced by the following factors, including personal interest, problem knowledge, perceived level of information available on the Web, ease of finding information, level of importance and seeking information on information problems in order from general to specific. Personal interest and problem knowledge were the major factors during assigned information problem ordering. Implications of the findings and further research are discussed. The relationship between information problem ordering and gratification theory is an important area for further exploration.

    Abstract
    According to many studies, social network sites (SNS) have become some of the most popular online destinations. It has been pointed out that very little is known about the psychosocial variables that predict people's use of these websites. In this article, our general objective is to understand behavioral intentions to use SNS employing the well-known unified theory of acceptance and use of technology (UTAUT), which has been validated in a number of studies. Data were collected through a questionnaire survey from a final sample of 1,039 social networking website users in Africa. We have shown that there are contexts, such as the African context, in which the UTAUT does not hold up. Explanations are provided to support the findings.
