Presents the design and implementation of a reliable multipeer protocol (RMPP), which is written in Java and is suitable for applications in the area of distributed virtual environments (DVEs). Discusses motivation, protocol classification, design goals and the error recovery algorithm and lists implementation issues. Presents two possible…

As scientists seek to develop machines that can "learn," that is, solve problems by imitating the human brain, a gold mine of information on the processes of human learning is being discovered, expert systems are being improved, and human-machine interactions are being enhanced. (SK)

Argues that access to hypertext documents in read-only forms contradicts the assumption that hypertext removes the distinction between author and reader, and discusses the implications for authors of hypertext documents. The creation of hypertext versions of journal articles and a database of such articles are described. (four references) (CLB)

Planning for microcomputer design and implementation should follow a six-step, classical corporate planning paradigm. The two most helpful tools to accomplish hardware implementation and staff development are setting goals and letting personnel know how these goals will be achieved. (MLH)

Describes a Minnesota school district's approach to managing a day care program, highlighting the integrated database management system used to automate the billing process and to provide complete data concerning the program and its enrollees, constituents, and services. Presents several guiding principles for designing a system matched to program…

Compares database characteristics, access, display, editing, new records, hard copy products, hardware, and price of CD-ROM catalog production products from seven vendors: Gaylord Information Systems; General Research Corporation; The Library Corporation; OCLC; Solinet; Utlas; and the Western Library Network. (MES)

Discusses the need for system upgrades of automated library systems in order to support ongoing software releases; obtain new functional modules; satisfy new library requirements; conform to new industry standards; and utilize new technology. Guidelines are presented for deciding when to upgrade and implement changes in these areas. (11…

Surveys areas of vulnerability for library databases, provides guidelines to minimize the threat of disasters, and outlines recovery procedures. Topics covered include planning for natural catastrophes, designing physical and data environments, prevention of computer failure, vendor failure, and steps for developing a disaster prevention and…

Discusses conceptual frameworks for the designing process, including conclusion-oriented design and decision-oriented design; describes the systemic quality cube of design that incorporates process, product, efficiency, and effectiveness and considers total, global, and systemic quality; and discusses present applications, including computerized…

Discussion of the design of information systems for exchanging educational research-based information focuses on the development of the Educational Resources Information Center (ERIC), British Education Index (BEI), Canadian Education Index (CEI), and Australian Education Index (AEI) and examines how they meet the challenges of educational reform…

Reviews and summarizes "Things That Make Us Smart," a book by Donald Norman that defends human attributes in the age of electronic systems. Topics include human performance; kinds of cognition; kinds of learning; design principles for electronic performance support systems; and examples. (LRW)

Examines the implications of incorporating user-centered design within information systems design practices. Highlights include a definition of user-centered design based on human-computer interface; questions asked about users, including outcome, process, and task variables; and three criteria for when to use this approach in information systems…

Discussion of multimedia computing and multimedia information systems that contain audio and video data focuses on how to implement buffer sharing in continuous-media systems based on slots and portions. Disk utilization and transition periods are considered, and future work is described. (LRW)

Describes the architecture of a distributed, networked, multimedia learning environment for macroeconomics, which employs gaming and simulation methods. Details include a conceptualization of the system and discussion of its function and structure. (JKP)

Reports on an exploratory study which used tracking records and evaluation questionnaires to examine the ways students use a hypermedia system. Findings in the following areas are discussed: enjoyment, ease of use, perception of system control, actual search strategies, perceived purposive search strategies, and effectiveness of search strategies.…
