Grid computing allows large groups of computers (either in a lab, or remote and connected only by the Internet) to extend extra processing power to each individual computer to work on components of a complex request. Grid middleware, recognizing priorities set by systems administrators, allows the grid to identify and use this power without…

This study examined factors (user satisfaction with computer information system function, desired involvement, attitudes toward computer information system staff, and user beliefs about the system) motivating users to become involved in new computer system development and found that user overall satisfaction with computer information system…

Analyzes the requirements for constructing collaborative learning activities in distance computer assisted learning (CAL) systems; shows why an active database can satisfy the requirements with a collaborative homework example; and proposes procedures for using an active database to construct collaborative learning activities in distance CAL…

Evidence exists that many students experience difficulties in comprehending the complexities of instructional system design (ISD), and they simply memorize its principles, with low levels of understanding. This article explores what tasks a student who takes an ISD course does as he or she performs a project of systematic and systemic…

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)
