    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
    Paper presented at the 1992 IATUL seminar in Tallinn, estonia: 'Universal Availability of Publications in Science and Technology including those on the history and philosophy of grey literature' on UAP policy and practice. Discusses surveys conducted at the Helsinki Univ. of Technology Library analysing the use of the online catalogue. Covers the Internordic Study 'Monitoring the Online Catalogues of the Nordic Technical University Libraries', whose aim was the promotion of end-user accessibility to information as part of a training program. Users' search behaviour was observed during the course on the library's TENTTU information retrieval system. Analyses the transaction log files of end users. Presents statistics on the distribution of search elements in free text and field codes and the use of Boolean operators. Comments on a software package enabling analysis of the interaction between the system and the end user. This may be useful to evaluate training programs

    Abstract
    Reports of a study in a Chilean university library, comparing 100 users of online databases and CD-ROMs with 100 users of non-computerized bibliographical resources. Results showed that users tended to be teachers / researchers, and potential users were postgraduate students. Comparison of search results showed online searching improved results and saved time. The chief reasons for non-use were ignorance of the service and use of own personal computer. The study indicated the need to review policy on database acquisition and improve promotion of the service. In general, librarians should motivate greater use of online searching by providing skilled intermediary services to maximize uptake

    Abstract
    With the rapid diffusion of the Internet, researchers, policy makers, and users have raised concerns about online privacy, although few studies have integrated aspects of usage with psychological and attitudinal aspects of privacy. This study develops a model involving gender, generalized self-efficacy, psychological need for privacy, Internet use experience, Internet use fluency, and beliefs in privacy rights as potential influences on online privacy concerns. Survey responses from 413 college students were analyzed by bivariate correlations, hierarchical regression, and structural equation modeling. Regression results showed that beliefs in privacy rights and a psychological need for privacy were the main influences on online privacy concerns. The proposed structural model was not well supported by the data, but a revised model, linking self-efficacy with psychological need for privacy and indicating indirect influences of Internet experience and fluency on online privacy concerns about privacy through beliefs in privacy rights, was supported by the data.

    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.

    Abstract
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web
