Abstract

Examines the assumption that people want to be presented with as many different media as are possible in a given application. Reports on an exploratory study designed to assess the media preferences og the 'person on the street' when presented with the choice of 7 different media combinations to find out some unknown thing in a public space. Findings suggests that people do not always prefer to access as many different media as are available. There was a bias toward having some media combination that includes graphics, but there was also some bias against having information presented using sound in a public space

Abstract

Increased enrollments, changing student expectations, and shifting patterns of Internet access and usage continue to generate resource and administrative challenges for colleges and universities. Computer center staff and college administrators must balance increased access demands, changing system loads, and system security within constrained resources. To assess the changing academic computing environment, computer center directors from several geographic regions were asked to respond to an online questionnaire that assessed patterns of usage, resource allocation, policy formulation, and threats. Survey results were compared with data from a study conducted by the authors in 1999. The analysis includes changing patterns in Internet usage, access, and supervision. The paper also presents details of usage by institutional type and application as well as recommendations for more precise resource assessment by college administrators.

Abstract

An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.

Abstract

Digital repository migrations present a periodic opportunity to assess metadata quality and to perform strategic enhancements. Lafayette College Libraries implemented OCLC FAST (Faceted Application of Subject Terminology) for its digital image collections as part of a migration from multiple repositories to a single one built on the Samvera Hyrax open-source framework. Application of FAST has normalized subject headings across dissimilar collections in a way that tremendously improves descriptive consistency for staff and discoverability for end users. However, the process of applying FAST headings was complicated by several features of in-scope metadata as well as gaps in available controlled subject authorities.

Abstract

Reports results of an evaluation of the Online at PA Libraries project (Autumn 1996 to Autumn 1997), funded by Bell Atlantic and administered by the Pennsylvania Dept. of Education's Office of Commonwealth Libraries and the Schuylkill Intermediate Unit, which has had a significant impact on the provision of Internet based information services and resources to Pennsylvania public library users. 4 surveys were conducted: a survey to assess the participating libraries' expectations concerning the project; a user survey to determine user satisfaction, demographic and overall project and Internet assessment; and 2 training evaluation surveys conducted at the start and at the follow up stage of the project. The project has provided a statewide demonstration of what can be done to improve quickly and significantly the statewide public library services; to connect public libraries to the Internet and provide a range of new services and resources to their communities; and to 'junpstart' libraries, librarians and citizens into the global networked society

Abstract

End users at Univ. of Southern California (USC) have free access to the last 10 years of MEDLINE via local online system known as USCInfo. Librarians at USC Norris Medical Library provide documentation and offer formal and informal training on the use of the system to search MEDLINE. To assess the educational needs of the end users, 643 searches were analysed. Although a high proportion (84%) of the searches were judged to be successful, the use of MeSH to obtain optimal results was low; only 20% of all successful subject searches employed MeSH. In addition, the advanced features of MEDLINE were underutilized. While it is promising to learn that many end users are obtaining positive results, methods which will encourage end users to improve their retrieval need to be developed

Abstract

This article focuses on the relevance judgments made by health information users who use the Web. Health information users were conceptualized as motivated information users concerned about how an environmental issue affects their health. Users identified their own environmental health interests and conducted a Web search of a particular environmental health Web site. Users were asked to identify (by highlighting with a mouse) the criteria they use to assess relevance in both Web search engine surrogates and full-text Web documents. Content analysis of document criteria highlighted by users identified the criteria these users relied on most often. Key criteria identified included (in order of frequency of appearance) research, topic, scope, data, influence, affiliation, Web characteristics, and authority/ person. A power-law distribution of criteria was observed (a few criteria represented most of the highlighted regions, with a long tail of occasionally used criteria). Implications of this work are that information retrieval (IR) systems should be tailored in terms of users' tendencies to rely on certain document criteria, and that relevance research should combine methods to gather richer, contextualized data. Metadata for IR systems, such as that used in search engine surrogates, could be improved by taking into account actual usage of relevance criteria. Such metadata should be user-centered (based on data from users, as in this study) and contextappropriate (fit to users' situations and tasks).

Abstract

Recreational reading among young people is reportedly on the decline in the United States. Some researchers have suggested that supporting children's strategies for book selection is crucial to encouraging children to engage with books, indicating that improving these strategies might increase the amount of reading they do. In response, this study explores how elementary-school children select books for recreational reading using a digital library. The work extends traditional models of relevance assessment with reader-response theory, employing the concept of aesthetic relevance: the potential of a document to provide a suitable reading experience. Individuals define aesthetic relevance in personal terms and apply it as they assess documents, much as they do in traditional relevance assessment. This study identified a total of 46 factors organized along seven dimensions that influence children's assessment of the aesthetic relevance of books during selection. The analysis yielded differences in the prevalence of the aesthetic-relevance factors that children mention at various stages of book selection. In addition, the children exhibited differences by age and subtle differences by gender in the frequency of mention of various aesthetic-relevance factors. Recommendations drawn from the findings are offered to improve systems design and literacy education in order to enhance children's access to books and to promote recreational reading.

Abstract

Facilitating engaging user experiences is essential in the design of interactive systems. To accomplish this, it is necessary to understand the composition of this construct and how to evaluate it. Building on previous work that posited a theory of engagement and identified a core set of attributes that operationalized this construct, we constructed and evaluated a multidimensional scale to measure user engagement. In this paper we describe the development of the scale, as well as two large-scale studies (N=440 and N=802) that were undertaken to assess its reliability and validity in online shopping environments. In the first we used Reliability Analysis and Exploratory Factor Analysis to identify six attributes of engagement: Perceived Usability, Aesthetics, Focused Attention, Felt Involvement, Novelty, and Endurability. In the second we tested the validity of and relationships among those attributes using Structural Equation Modeling. The result of this research is a multidimensional scale that may be used to test the engagement of software applications. In addition, findings indicate that attributes of engagement are highly intertwined, a complex interplay of user-system interaction variables. Notably, Perceived Usability played a mediating role in the relationship between Endurability and Novelty, Aesthetics, Felt Involvement, and Focused Attention.

Abstract

The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
