A total of 685 articles in "Mental Retardation,""American Journal of Mental Deficiency," and "American Journal on Mental Retardation" from 1980 through 1989 were examined. The mental retardation classification system developed by the American Association on Mental Retardation was used in over 50 percent of the…

Investigation of retrieval performance of controlled vocabulary derived from natural language terms in tables of contents and book indexes assumed that controlled vocabulary representative of users' queries should adequately represent documents' contents. Queries were indexed using Library of Congress Subject Headings (LSCH), Dewey Decimal…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Shows how to automatically construct a classification of users and a clustering of documents and cross-references among clusters based on users' information needs. Feedback in the construction of this classification and clustering that allows for the classification to be changed to reflect changing needs of users is also described. (22 references)…

Concludes that the three main articles in this issue represent a significant milestone in defining rural education. Points out that measuring the effectiveness of rural schools will be more difficult and that federal policy should provide resources for the development of alternative rural school models. A defensible classification system needs to…

Examined whether preschool children focus on a small number of attributes or attend to whole exemplars in learning basic categories for fictitious animals. Found little evidence that children employed rules, but found strong evidence that children encoded exemplars as integrated wholes during category training. Discusses implications for theories…

The prevalence of epilepsy was correlated with the severity and type of encephalopathy of 1,023 individuals with mental retardation. A total of 326 individuals were diagnosed with epilepsy. Results indicated a low percentage of epilepsy in chromosomic-genetic and young adult encephalopathies and a high prevalence when the neurodeficit was…

Reviews the 1992 literature on subject analysis. Highlights include theoretical foundations; subject cataloging; machine-assisted subject cataloging; machine-executed subject cataloging; classification systems; subject headings and indexing; online subject access; and special materials. (Contains 133 references.) (LRW)

A survey of 128 undergraduate female students indicated that 44% had experienced cross-gender sexual play as children, which was often seen as involving persuasion, manipulation, or coercion. A typology of six kinds of sexual play experiences was derived. Discussion focuses on the differentiation of childhood sexual abuse from play and gender…

This response to HE 531 678 argues that, although there is evidence that accelerated programs designed for gifted children can be effective, most emphasize enrichment, not true acceleration. Enrichment is seen as appropriate for all students, not just the highest-achieving 3%. (MSE)

The conceptual categories that children have developed in their second year were studied in five experiments using object manipulation tasks. Subjects included 152 children from 18 to 31 months of age. These very young children had formed global conceptions of many domains of objects. (SLD)

This article reviews recent research on phonological development and characteristics associated with different forms of delay. Language-delayed students are considered categorizable at 24 months as either "late talkers" with no major deviations from patterns of normal acquisition or disordered students whose developmental patterns are markedly…

This paper responds to a critique (EC 601 489) of a paper on the possible involuntary nature of self-injurious movements in persons with mental retardation, resulting from undiagnosed frontal lobe seizures. The response discusses electroencephalographic techniques, the importance of observable ictal phenomena, the need for other corroborating…

Comparisons of the Wilcoxon test, Friedman test, and repeated-measures analysis of variance (ANOVA) on ranks in a computer simulation show that the Friedman test performs like the sign test whereas the ANOVA performs like the Wilcoxon test. Classification of these tests in introductory statistics textbooks should be revised. (SLD)

Presents new system for describing, classifying, and coding problems of adult clients of social workers. Notes that new system uses organizing concept of "person-in-environment" (PIE) to describe social role; environmental, psychiatric, and health problems; and client strengths. Discusses concepts and theories incorporated into PIE…
