A generalized Keynesian "general equilibrium" model, derived largely from macropolitical considerations, is presented. (Author)

Describes the Probabilistic Relational Universal Fuzzy (PRUF), a relation-manipulating language which serves the purposes of: (1) precisiation of expressions in a natural language; (2) exhibiting their logical structure; and (3) providing a system for the characterization of the meaning of a proposition by acting on a collection of fuzzy relations…

Reports the results of a study of cataloging records input into the Ohio College Library Center (OCLC) data base by participating libraries (non-MARC records). The records were analyzed to determine the various fields where most errors occur, as well as the types of cataloging errors. (Author/VT)

Several approaches to problem solving are reviewed, followed by a brief overview of simulation, including its definition and some of the strong and weak points of the literature. It is argued that simulation is itself a problem-solving endeavor and that justifying the heuristic use of simulation requires evidence that it fosters general…

Reports an experiment in which verbalized tape-recorded searches on five subject indexes reveal the linguistic processing taking place. Extracts from the search transcriptions are given, and the search processing modes of seeking, scanning, and screening are discussed. (Author/KP)

Responds to Heppner and Krauskopf's article on an information processing approach to personal problem solving by presenting shortcomings in the approach, notably its failure to fully exploit the available information processing concepts to reconceptualize personal problem solving specifically or counseling in general. Nonetheless, sees the…

This article specifies some basic considerations regarding information processing and perception and suggests two related considerations when attempting to provide for learning. (Author)

Library text production and information retrieval applications require a programing language with string processing facilities. The most useful languages are SNOBOL, COMIT APL and PL/1. (Author/LS)

Measures of visual information processing in dyslexic and normal children were compared. Significant differences were found between dyslexics and normals at early stages of visual information processing. (ST)

The technique for machine-aided indexing developed at the Defense Documentation Center (DDC) is illustrated on a randomly chosen abstract. Additional text is provided in coded form so that the reader can more fully explore this technique. (2 references) (Author)

Groups of middle-aged and elderly women were compared on problem solving behavior. Results indicated a decline in the use of classification skills among the elderly and an inability to use constraint-seeking questions. (ST)

This paper describes how the problem of resolution of syntactic ambiguities is approached in the parser PHRASE, developed for use in experiments in automatic indexing and extracting. PHRASE is a multi-level parser for declarative sentences, in which the syntactic structure is built up in four stages. (10 references) (Author)

A method of constructing a check digit for nonconventional chemical codes is described. (5 references) (Author)

A system of automatic indexing based on Baye's theorem is described briefly. (18 references) (Author)

The author describes a method of automatic indexing using the assignment of priority to verbs which may also be viewed as a simulation of how a person classifies documents. (15 references) (Author/SJ)
