Two classification schemes for social work knowledge are proposed. The first scheme is based on a definition of the profession's knowledge base. The second scheme is based on the concept that social work focuses on the interface between person and environment. (RC)

Discusses a number of issues that bear on the scientific usefulness of sentence verification models. These models explain how information from a sentence is compared to its referent. (Editor)

Examines parallel computer architecture and the use of parallel processors for text. Topics discussed include parallel algorithms; performance evaluation; parallel information processing; parallel access methods for text; parallel and distributed information retrieval systems; parallel hardware for text; and network models for information…

Identifies four components of a good predictive lossless image compression method: (1) pixel sequence, (2) image modeling and prediction, (3) error modeling, and (4) error coding. Highlights include Laplace distribution and a comparison of the multilevel progressive method for image coding with the prediction by partial precision matching method.…

Posits that intelligibility is a persistent problem in interactive multimedia and hypermedia. Describes the Art of Memory, a visual and symbolic mnemonic method used to map new information onto familiar and symbolically different structures. Presents the Art of Memory as a way to offer insight into intelligibility. (PA)

An analysis to ascertain which electronic data processing (EDP) systems are most flexible in processing wide ranges of volumes efficiently. A simulation model of the job environment of three common EDP systems provides information on the shape of their cost functions in the neighborhood of optimality. (Author/LS)

The report presents both a way of looking at perceptual mechanisms in nervous systems in terms of distributed information processing, and a way of creating computer models of parts of nervous systems. The first notion views a nervous system as a collection of interacting parallel-operating computation units, each of which has some part of the…

An explicit model of the process of quantification which involves the operations of subitizing and counting is described. The general model states that quantification of n items takes place via subitizing when n is less than five and via subitizing and addition (that is, counting) when n is five or larger. The explicit model is stated in the form…

This paper deals with the organization of two important areas which interact strongly: information science and decision-making. Both are commonly and extensively used in a variety of ways and share an equally commonly and extensively used variety of definitions. This paper deals with the mutual interaction between information science and…

The frequent reference by geographers and cartographers to 'the language of maps' is made precise by clarifying ways in which maps and other formulations of geographic information constitute a language. Aspects of this language are identified, and emphasis is placed on the use of linguistic concepts for study of models of geographic information…

Expands the notion of problem by creating a pluralistic theory of problems that embraces both the limited concept created by the information-processing school and an epistemic concept of problem. (JAD)

Reports on study analyzing 13 abstracting and indexing (A&I) operations in order to ascertain those steps in specific processes that added value (i.e., were of benefit to user in making choices from information displayed). The user-driven/value-added model and a summary of value-added processes in A&I services are highlighted. (11…

Models of development and models of memory reflect either a mechanistic or organismic world view. A merger of the information-processing models of memory and qualitative models of development is suggested, and has valuable implications about the possible nature of "locus" of memory development (ST)

An experiential learning model based on information processing is the foundation for the learning combination lock model, which depicts how six factors (or tumblers) may be selected and combined to develop effective learning opportunities. The factors are places and elements, milieu, senses, emotions, forms of intelligence, and ways of learning.…

This article highlights basic issues that have hindered e-learning systems from becoming the revolutionary force it could be for education. While current systems aim to foster significant improvements in learning, this article argues that most systems are still limited to just being online repositories. This and the lack of learning…
