Systems dynamics, a computer-based tool for visualizing how parts of an organization work together over time, is a valuable tool in administrative decision making. Feedback loops among elements mimic complicated behavior in real or imagined situations. An experiment using the technique with a simple research funding model validated its utility.…

Discussion of virtual reality (VR) focuses on the promise that VR offers for information systems by describing current systems which use VR and by projecting possible developments for the future. Types of information problems which could be helped by VR are considered, as well as those that could not be helped. (Contains 13 references.) (LRW)

Examines the relationship between information and democracy through a framework of six stereotyped assumptions regarding ontology and epistemology, i.e., dogma, naturalism, cultural relativity, constructivism, postmodernism, and communitarianism. Implications for the design and implementation of information systems are discussed. (Contains 93…

This article describes the stages in developing a special education expert system: orientation, development of a theoretical framework, generation of content for the system databases, and checks for consistency and logic/revision. It explains the synthesis and application required to build the content for the system and discusses typical problems…

Discusses the concept of international librarianship (particularly in Europe), the unique characteristics and role of national libraries, librarians working in national libraries, and the role of information strategy systems and information technology in national libraries. (LRW)

Yale University (Connecticut) uses a "constructive evolution" method of coping with maintenance and fine-tuning of aging information systems. In this process, system developers form partnerships with user department representatives to plan and coordinate system changes. Evolution of the personnel/payroll system over five years provides…

Analyzes the skill acquisition sequence in using a software package and proposes advent models for investigating patterns of user interaction with information systems. The use of transaction log data is explained, advent function analysis is described, and tests of the models on longitudinal data are discussed. (26 references) (LRW)

Suggests basic elements of spatial education appropriate to geographic information system (GIS) course curricula. Describes the need for integration of GIS education and GIS training. Discusses hardware/software configurations, approaches to the creation of laboratory facilities, and approaches, rationales, and technical considerations in the…

Evaluated police information systems in 149 Illinois police departments using satisfaction and impact measures. Police report high rates of satisfaction but little impact on operations and decision making beyond that of a positive impact on reporting capacity. Police generally do not view these systems as sources of decision support. (SLD)

A mainframe computer installed at a school district had all information online within a 24-month period. The key elements to success were adequate research and staff input, open communication, exemplary training, and a data-processing staff that made site visits to help with hardware or software problems. (MLF)

The paper proposes a zero concept, health-oriented approach to applying informatics to two health care problems: first, the lack of easily understood and used terminology linking health problems and interventions to the concept of "health"; and second, the lack of a unifying principle on which to base all aspects of health care. (DB)

Discussion of users' persistence in scanning displays of postings on computer-driven information systems focuses on a study of the Library Computer System (LCS) in Illinois, an online library system that provides access to an academic library collection. The use of transaction log analysis is described and results are analyzed. (12 references)…

System of Interactive Guidance and Information (SIGI) Plus is a revision of SIGI based on the needs of adults. Two revised features are Self-Assessment (rating work values and interests in terms of what adults like and are competent in) and Coping (identifying the practical problems and barriers facing adults in education, training, and…

In evaluating 12 career-oriented and educational software packages to determine the presence and extent of gender bias, researchers found that gender fairness had not been achieved. They concluded that the evaluation of software should follow established gender-fair guidelines so that gender-biased materials will not be used in an educational…
