Presents two activities on addition, one for classifying and one for symmetry. (ASK)

Indexing is the preprocessing of information to enable its retrieval, ranging from classification-based (precoordinate) to keyword searching (postcoordinate) approaches. This article describes a framework for modelling information retrieval systems in terms of sets of objects, relationships, and functions and discusses the application of indexing…

The second of two parts, this article develops a taxonomy of value-in-use for library and information services based on user assessments and proposes methods and instruments for similar studies of library and information services in general. Divides value of services into three classes: reasons for use; quality of interaction; and worth, benefits…

Five experiments examined matching to sample procedures among preschoolers. Results indicated that children selected taxonomic comparisons more often than thematic comparisons, independent of age, gender, instructions, order of trial type, specificity of feedback, presence of unrelated third comparisons, and level of taxonomy. Instructions to…

This response to "Behavior Disorders: A Postmodern Perspective" (David Elkind) rejects the postmodern notion that there can be no common narratives and proposes three possible metanarratives that could be useful in thinking about behavioral disorders: democracy, spirituality, and the notions of Nick Hobbs.

Describes the slot-filler model of taxonomic knowledge development in which preschoolers derive "slot-filler" categories from event schemas. Maintains that the model has received considerable support across methodologies, ages, and sociocultural contexts. Argues that Krackow and Gordon's theorizing and methods could not lead to reliable,…

Analyzes four topics: (1) everyday discourse and judgments about language usage; (2) "social linguistics" and explanations for language differences in terms of categories such as class and gender; (3) the proposition that identity is constructed by language; and (4) the extent to which social categories are discursively constructed. (SK)

Examined relationships among theory of mind construct of intention and false belief, problem-solving ability, metacognitive regulation, and strategy use in 39 preschoolers. Found significant correlations between strategy use and theory of mind, and metacognitive regulation and theory of mind. A moderate, but nonsignificant, correlation was found…

When scholarly articles and clinical reports have scores of authors-what Cronin has termed "hyperauthorship"-the precise nature of each individual's contribution is often masked. A notation that describes collaborators' contributions and allows those contributions to be tracked in, and across, texts (and over time) offers a solution. A proposal…

Analysis of data collected from a Persian-English bilingual infant over 10 months beginning at age 9 months found that, in comparison to the monolingual child in a previous study by Halliday, both children developed pragmatic functions from a very early age. A categorization system is proposed to facilitate the analysis of child language…

Considers relationships between the fields of library history and historical bibliography. Topics include the act of reading versus the cultural institutions of reading; description and cataloging; book production; paradigm shifts; classification systems; electronic libraries; and the need for theory to grow out of practice. (LRW)

Compares and assesses research published in the 1980s-1990s in four consumer sciences journals in terms of specialization; institutional affiliation of the researcher; source of data, sample size, topical classification, and research methodology; and statistical analysis. Appendices contain 16 summary tables and lists of articles from each…

This article uses a short story by Jack London to discuss the classification of individuals with mental retardation and argues that mental retardation and its various definitions are manifestations of the typological thinking that inevitably creates a simplistic and misleading aggregation of people with very diverse needs and characteristics.…

Discusses Needham's findings that infants individuate objects by feature, within the framework of brain mechanisms that index or track individual objects, drawing upon theories of attention and working memory developed in the study of adults. Considers Needham's work as contributing to an understanding of categorization and the effect of object…

Describes the procedures and benefits of using Library of Congress Playing Card games to teach library staff number sequencing and thereby reduce shelving errors. Appendixes include illustrations of the cards themselves, including table showing which call numbers correspond to various suits and values; training handouts; and two proposed studies.…
