Reviews history of psychiatric nosology and the use of interview data as a vehicle for formulating clinical inferences. Focuses on qualities of structured interviews as well as procedures for constructing these indices and methods for establishing their psychometric properties. Reviews practical and theoretical limitations relating to formal…

Categorized 56 patients with chronic schizophrenia into 2 groups based on traditional diagnostic subtypology. Compared groups on indices of cortical and subcortical cerebrospinal fluid (SCF) volume to explore whether more virulent nonparanoid disorder was linked to cortical/subcortical morphological brain abnormalities. Two groups differed…

Discusses research describing Web page and link classification systems resulting from a content analysis of over 75 Web pages. Topics include the decision-making processes of Web page authors and readers; syntactic analysis of labeled and isolated anchors; expansion and resource links; and where links lead. (Author/LRW)

Presents the findings of an empirical investigation of Internet shopping in Singapore. Compares Internet buying behavior between potential Internet buyers and non-Internet buyers, and concludes that the classification of different types of products and services will significantly influence consumer choice between a retail store and the Internet.…

Content analysis of data from 156 proteges identified 15 types of negative mentoring experiences clustered in five themes: mismatch within dyad, distancing behavior, manipulative behavior, lack of mentor expertise, and general dysfunctionality. Proteges reported negative mentoring most often when mentors had dissimilar attitudes, values, and…

Responds to Waldo and Bauman's Goals and Process matrix. Underscores the increasing value of standards for group work established by the Association for Specialists in Group Work in shaping group work training, practice, and research. Points out that standards are not intended to classify independent group offerings. Suggests alternative…

Authors respond to issues raised by commentators concerning their Goals and Process (GAP) matrix. Discuss themes apparent in several commentaries, including nomenclature, the need for a new model, complexity of the model, the omission of task/work groups, and revision of the Association for Specialists in Group Work's model.

Asserts that typological thinking, the belief that individual differences diverge around an underlying type of essence, has persisted regarding mental retardation and prevents the appreciation of individual differences and human dignity in the mental retardation field. Past and present controversies over the definition of mental retardation are…

Fourier analyses of children's behaviors were conducted over a sequence of five consecutive study/recall trials to identify temporal patterns. Findings pointed to a global strategy in which children learn the items' categories before learning them individually. There was little qualitative difference in temporal organization for second graders and…

Maintained that preschoolers' class inclusion task judgments and justification may be modeled as mixtures of different probability distributions, with different response strategies equivalent to different distributions. Found that justifications lagged behind judgments in development. Concluded that, if a single response variable is to be…

Presents a broad definition of "testlet" and suggests a framework for classifying types of testlets. Considers several issues that bear on the conceptualization of testlets and analyses of scores from tests composed of testlets. Suggests some research topics that seem particularly important to advancing the meaningful and appropriate use…

Discusses T. D. Wilson's research emphasis on situating the investigation of information behavior within the context of the everyday world of work; considers embodied cognition; and presents two approaches to the investigation of classification in context: classification as scaffolding, and classification as infrastructure. (Author/LRW)

This article addresses the characterization and circumvention of E. H. Simpson's paradox in designs involving two ordered variables and illustrates the recommended procedure using a two-sample application involving estimation of correlation and a single-subject application involving the estimation of lag(1) autocorrelation. (Author/SLD)

Argues that technical communication editing is most effective if it deals with structure first, and that structure deficiencies can be detected by applying a range of logical analysis criteria to each text part. Concludes that lists, headings, classifications, and organograms must comply with the laws of categorization and relevant logical…

Synthesizes MacLaury's vantage theory, Barsalou's frame theory, and the relation between similarity, commonality, and difference. Frame theory elaborates on the structural components of mental representations, while vantage theory elaborates on the processing by which these components are integrated. (Author/VWL)
