Describes a model for dynamic electronic performance support systems based on NNAble, a system developed by the training group at Apple Computer. Principles for designing dynamic performance support are discussed, including a systems approach, performer-centered design, awareness of situated cognition, organizational memory, and technology use.…

Discussion of electronic performance support systems (EPSS) focuses on performance support engineering and its role in designing performance support systems. Highlights include the organizational performance/learning cycle model; a systems approach to EPSS; computer-based training and other EPSS methodologies; and future possibilities. (LRW)

The point is made that systems thinking should be combined with dialectical thinking and constructivist thinking for effective systems design and systems change. To establish a context, a set of assertions on "How the World Works" in regard to systems design and systems change in education is laid out, as value assumptions undergirding…

Presents reasons for choosing a connected computer system for student use in secondary schools. The systems approach is discussed; two alternatives are compared, a central computer and a local area network (LAN) of microcomputers; software is described; and two scenarios of LAN use are presented. (four references) (LRW)

Discussion of the problem of control in documentary information retrieval (IR) systems focuses on feedback mechanisms. Information needs are discussed, particularly the Problem Oriented Information Need (POIN); the structure of an adaptive IR system is described; and the design of algorithms for automated IR systems is explained. (33 references)…

Discussion of information needs in a business environment focuses on how to build a shared information network. Highlights include the evolution of corporate intelligence systems; results of a survey that examined the information networking needs of large corporations; and a case study of the development of an information network at Citibank N.A.…

Discusses the issues influencing the design, implementation, and promotion of the Towers Perrin in-house text retrieval system. The discussion of factors influencing system design includes the organizational culture, the existing computer and communications network, and the availability of text retrieval software. Suggestions for in-house systems…

Discusses possible technical services functions in electronic libraries of the future. Highlights include acquisition of electronic information; bibliographic control, including MARC format, bibliographic utilities, subject headings, and classification; systems planning, development, and evaluation; systems support; organization of technical…

This paper examines general systems theory as it applies to higher education institutions. Using this approach, the university is viewed as a system (comprised of subsystems) that interacts with the external environment. The first sections of the paper review general systems theory and its application to management, and examine some theoretical…

Argues that there is a fundamental gap between the knowledge that the information systems development community values and that which cultural analysis yields. Suggests that developers, rather than trying to explain social behavior and knowledge with rules, should be concerned with the production of contesting rules and what the production tells…

Four articles respond to the Bader and Nyce position that it is unlikely cultural analysis will become a routine tool for information systems developers with these arguments: ethnographic work can aid software development; the problem lies with inappropriate application of social science methods; the problem is technique, not fundamentals; and…
