Abstract

During the fall 2001 semester 15 first-year undergraduates were interviewed about their information-seeking behavior. Undergraduates completed a short-answer questionnaire, the Measure of Epistemological Reflection, measuring their epistemological beliefs and searched the Web and an online public access catalog using tasks from the Reflective Judgment Interview that assessed their reflective judgment level. Undergraduates talked aloud while searching digital environments about the decisions they were making about the information they encountered while transaction analyses software (Lotus ScreenCam) recorded both their search moves and their decision-making through verbal protocol analysis. Analyses included examining the relationship between undergraduates' epistemological beliefs and reflective judgment and how they searched for information in these digital environments. Results indicated that there was a relationship between epistemological beliefs and reflective judgment and information-seeking behavior. Undergraduates' at higher stages of epistemological development exhibited the ability to handle conflicting information sources and to recognize authoritative information sources.

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

Reports results of a survey of 675 CD-ROM users at State University of New York at Albany Libraries, obtaining data from both questionnaires and actual search strategies. The primary aim was to investigate the effect of prior user training or assistance on CD-ROM search strategy. A statistically significant but weak relationship was found between prior rtraining and level of search skill. Other measures such as user status, department affiliation of major, age, sex, and number of previous CD-ROM uses were compared to search skill. Only user status and department affiliation or major were significantly correlated to search skill. Concludes that additional research is needed on the effectiveness of various types of CD-ROM training

Abstract

Faculty members from a major university were surveyed to explore the possible relationship between Internet usage and the following dependent variables: computer usage (length of time and perceived expertise), length of time of Internet use, perceived expertise of Internet use, and perceived utility of the Internet. 97% have an Internet account. Furthermore, computer literacy and length of computer experience are correlated with early adoption of the Internet, perceived utility of the Internet is correlated with computer literacy and with Internet usage, and usage is correlated with perceived expertise, but not with the length of time of Internet experience. Highly skilled computer users are more likely to use the network in a more intensive way and have higher appreciation of the network's potential

Abstract

This article attempts to verify the hypothesis of the document presentation order by an empirical, two-stage experiment. It aims to identify the relationship between number of documents judged and order effect. The results indicate that significant order effect takes place when 15 and 30 documents are presented. Sets with 45 and 60 documents still reveal the order effect. However, subjects are not influenced by order of presentation when the set of documents has 5 and 75 members, respectively.

Abstract

Reports results of a questionnaire survey of the user characteristics of Korean student user groups in searching OPACs. The study examined the use of 5 selected OPAC systems in 5 academic libraries in the Austin, Texas and North Texas areas. The objective was to provide information on the characteristics of a specific group of international college students from a developing country in order to assist system managers in the selection of OPAC systems. The major conclusions of this study were: the academic level and age of students affect the preference towards an OPAC, but academic major of the students does not affect the preference; system designers should prepare more specific instructions regarding searching methods; there is a negative relationship between the number of searching methods that the respondents knew in using OPACs and the frequency of manual card catalogue use; and menu driven systems should be the first selection of OPAC systems for Korean students. Proposes recommendations for the design, adoption, or management of a new OPAC system

Abstract

Describes a project, conducted with a development grant from the Kentucky Library Association's Academic Section, to design and produce a number of flip charts for use at OPAC terminals in 6 of the Louisville university libraries. The custom made flip charts were designed as point of use user training tools. Reports results of an analysis of OPAC transaction logs to measure the success of the flip charts. Comparisons were made among the types of searches conducted, the percentages of zero hits, and the types of errors found before and after the introduction of the flip charts to determine whether searching succes rates had improved or if searching strategies had changed. Results indicated that the presence of the flip charts had not brought about a significant change in searching success. Concludes that there is no substitute for professional librarians working in a one to one relationship with the OPAC user

Abstract

Examines the problem of a compelling online news delivery system by focusing on how mass media audiences and online users differ in their assessment of news. It employed a 2-wave USA national survey to study the perception of interactivity in mass media and computer networks and its relationship to the assessment of news. The 1st wave looked a national probability sample, ahile the 2nd targeted viewers of NBC Nightly News who responded to the show via e-mail. NBC respondents rated mass media to be less interactive, while they rated computer communication more interactive than the national sample. The NBC group also rated mass media news less important and of lower quality than did the national sample. Interactivity ratings did not predict mass media credibility assessment for either group. However, respondents who defined interactivity as cybernetic feedback or who contacted NBC by e-mail rated computer communication to be more credible than thos who did not

Abstract

This study reports an analysis of American Chemical Society electronic journal downloads at Cornell University by individual IP addresses. While the majority of users (IPs) limited themselves to a small number of both journals and article downloads, a small minority of heavy users had a large effect an total journal downloads. There was a very strong relationship between the number of article downloads and the number of users, implying that a user-population can be estimated by just knowing the total use of a journal. Aggregate users (i.e. Library Proxy Server and public library computers) can be regarded as a sample of the entire user population. Analysis of article downloads by format (PDF versus HTML) suggests that individuals are using the system like a networked photocopier, for the purposes of creating print-on-demand copies of articles.

Abstract

This study reports an analysis of referral URL data by the Cornell University IP address from the American Chemical Society servers. The goal of this work is to better understand the tools used and pathways taken when scientists connect to electronic journals. While various methods of referral were identified in this study, most individuals were referred infrequently and followed few and consistent pathways each time they connected. The relationship between the number and types of referrals followed an inverse-square law. Whereas the majority of referrals came from established finding tools (library catalog, library e-journal list, and bibliographic databases), a substantial number of referrals originated from generic Web searches. Scientists are also relying an local alternatives or substitutes such as departmental or personal Web pages with lists of linked publications. The use of electronic mail as a method to refer scientists directly to online articles may be greatly underestimated. Implications for the development of redundant library services such as e-journal lists and the practice of publishers to allow linking from other resources are discussed.

Abstract

The research reported here was an exploratory study that sought to discover the effects of human individual differences an Web search strategy. These differences consisted of (a) study approaches, (b) cognitive and demographic features, and (c) perceptions of and preferred approaches to Web-based information seeking. Sixtyeight master's students used AItaVista to search for information an three assigned search topics graded in terms of complexity. Five hundred seven search queries were factor analyzed to identify relationships between the individual difference variables and Boolean and best-match search strategies. A number of consistent patterns of relationship were found. As task complexity increased, a number of strategic shifts were also observed an the part of searchers possessing particular combinations of characteristics. A second article (published in this issue of JASIST; Ford, Miller, & Moss, 2005) presents a combined analyses of the data including a series of regression analyses.

Abstract

Data from Westminster Libraries on membership, borrowing frequency and stock use is compared with significant studies of public library use from the last 50 years. The article examines the extent of public library use, and the social and demographic factors influencing use. Analysis of book and audio-visual stock use indicates the concentration of demand on a few titles and subjects, and the relationship to what is in demand commercially. Aspects of public library use have remained constant over at least the last 50 years, and across geographical boundaries. Public libraries are used principally for leisure, for borrowing recent fiction, for useful non fiction related to immediate life interests, and for pop music. Quantitative data from library systems provides a different, probably more accurate, picture of the nature and extent of public library use.

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

Purpose - The study aims to examines two aspects of information seeking behaviour of physicists and astronomers including methods applied for keeping up-to-date and methods used for finding articles. The relationship between academic status and research field of users with their information seeking behaviour was investigated. Design/methodology/approach - Data were gathered using a questionnaire survey of PhD students and staff of the Department of Physics and Astronomy at University College London; 114 people (47.1 per cent response rate) participated in the survey. Findings - The study reveals differences among subfields of physics and astronomy in terms of information-seeking behaviour, highlights the need for and the value of looking at narrower subject communities within disciplines for a deeper understanding of the information behaviour of scientists. Originality/value - The study is the first to deeply investigate intradisciplinary dissimilarities of information-seeking behaviour of scientists in a discipline. It is also an up-to-date account of information seeking behaviour of physicists and astronomers.

Abstract

Purpose The purpose of this paper is to investigate the relationship between preferred choice of school subject and student information behaviour (IB). Design/methodology/approach Mixed methods were employed. In all, 152 students, teachers and librarians participated in interviews or focus groups. In total, 1,375 students, key stage 3 (11-14 years) to postgraduate, responded to a questionnaire. The research population was drawn from eight schools, two further education colleges and three universities. Insights from the literature review and the qualitative research phase led to a hypothesis which was investigated using the questionnaire: that students studying hard subjects are less likely to engage in deep IB than students studying soft subjects. Findings Results support the hypothesis that preferences for subjects at school affect choice of university degree. The hypothesis that a preference for hard or soft subjects affects IB is supported by results of an analysis in which like or dislike of maths/ICT is correlated with responses to the survey. Interviewees' comments led to the proposal that academic subjects can be classified according to whether a subject helps students to acquire a "tool of the Mind" or to apply such a tool. A model suggesting how IB may differ depending on whether intellectual tools are being acquired or applied is proposed. Practical implications The "inner logic" of certain subjects and their pedagogies appears closely linked to IB. This should be considered when developing teaching programmes. Originality/value The findings offer a new perspective on subject classification and its association with IB, and a new model of the association between IB and tool acquisition or application is proposed, incorporating the perspectives of both teacher and student.
