Four types of fundamental structures are briefly described and illustrated: the learning hierarchy, the procedural hierarchy, the taxonomy, and the model. Then a theoretical framework is presented for classifying types of subject matter content, and some implications of these content classifications are discussed. (VT)

This study assesses and characterizes lexical relationships among the major urban Syro-Lebanese varieties of Arabic. To achieve this quantitative analysis of degrees of similarity or differentiation, an analytical procedure based on lexical compatibility was developed. Secondarily, a classification of these varieties is presented as a by-product…

In this study, third and sixth graders were tested in a recognition memory task with short lists of items from either one or two categories to investigate the influence of categorical information on retrieval processes. (Author/SB)

This article examines the movement from 1939-1974 to organize American university libraries according to subject divisions. The origins of this form of organization are examined in early patterns of library organization and service, the need for subject access to library collections, the requirements of undergraduate students, and important…

Examines the differences between three systems of categorizing verbal communication acts. (MH)

Two models of intertask relations, Wohlwill's divergent-decalage and reciprocal-interaction patterns, were evaluated for their fit to cross-classification tables which showed the joint classification of 101 children's performance on all possible pairs of eight concrete operational tasks. (SB)

Proposes that the development of document-retrieval systems can benefit from the incorporation of conceptual modeling techniques, specifically classification, aggregation, and generalization. An array model is presented which has been designed especially for document retrieval. (Author/EM)

An alternative approach to the traditional diagnostic-prescrptive or medical model for classifying behavior disorders is proposed which considers topography of deviant behaviors, degree of exceptionality, nature of deviance, and events influencing the deviancy in the context of developing and monitoring education/treatment programs. (Author/CB)

Describes the basis for a simulation game classification based on the game image, which is created against a foundation of events that occur during the course of the game. Three characteristics of the game image--reflection of reality, dialog, and motivation--are defined, and game dialog types are discussed in detail. (MBR)

A total of 20 children between seven and 11 years of age and 20 adults categorized rules of perceived high social utility in social conventional terms in both public and private contexts; but they categorized rules of perceived low social utility in social conventional terms in private contexts and in personal terms in public contexts.

This review of the 1987 journal literature on descriptive cataloging covers (1) description codes and research; (2) authority control; (3) cataloging operations; (4) special topics, including contract cataloging, copy cataloging, retrospective conversion, and preservation; (5) catalogers; and (6) education.

The study of folk speech, which traditionally included only regional dialects, has evolved to include cultural and generational dialects. This article discusses how folk speech study has come to include a range of dialects and a variety of sociolinguistic trends. (JL)

Reviews the bibliometric laws of Bradford, Leimkuhler, Mandelbrot, Lotka, Brookes, and Zipf, and classifies them in two groups, based on the use of mathematical logic and equivalency. (8 references) (CLB)

Discusses the problem of assigning subjects to one of several treatments based on their test scores. The success of each treatment is measured by different criterion. (RB)

Two experiments using the habituation-dishabituation paradigm examined infants' ability to form and retrieve a basic-level category. Results indicated that infants categorized when tested immediately and after a five-minute delay. (PCB)
