Based upon a review of literature on classroom play and observations of two girls' free play in a nursery school classroom, posits a new model for describing classroom play. Play can be understood in terms of a progression of a range of simulations that involve the influences of materials, social relations, real-world experience, and decisions…

Generated empirical, statistically based typology that used both symptom data and social functioning dimensions to define subtypes of 218 seriously and persistently mentally ill patients. Data were factor analyzed and then submitted to cluster analysis that yielded five meaningful patient subtypes. There were significant subgroup differences on…

Suggests that in learning and development, the process of comparison can act as a bridge between similarity-based and rule-based processing. A structure-sensitive comparison process, triggered by experiential or symbolic juxtapositions can: (1) facilitate understanding of structural commonalities and the abstraction of rules; and (2) facilitate…

Examines previous research on keyword-search techniques and evaluates a keyword classification scheme. Compiled a list of 1056 management information systems (MIS) keywords from 14,676 articles in 27 (MIS) journals and compared it to an existing list (Barki). Concludes that a comprehensive keyword-classification system is needed for enhanced MIS…

Examines job classification studies in public libraries, focusing on point-factor classification systems. Discusses job descriptions, job auditing biases, preparedness, what not to say to auditors, and the appeals process. Outlines typical factors in a job classification: decision-making, guidelines, education, experience, complexity, supervision,…

Discussion of context focuses on the various contexts surrounding the design and use of intelligent tutoring systems and proposes an initial framework of contexts by classifying them into three major groupings: interactional; environmental, including classifications of knowledge and social environment; and objectival contexts. (Author/LRW)

Presents a mechanism for organizing and manipulating groups of nodes and links in large World Wide Web sites. Topics include the Web as a hypertext system, information-retrieval problems, a model for organizing Web sites based on perspectives, a prototype system, versioning, configuration management, parallel activities, and future plans.…

An analytic procedure is presented that estimates the expected benefits of personnel classification decisions for which it is assumed that the available criterion estimates are both equi-correlated and equally valid, with equal quotas for the jobs, and the equal importance of all jobs. The numerical method developed for the estimation is…

The effectiveness of the affect trait scales of the revised Multiple Affect Adjective Check List (MAACL-R) (M. Zuckerman and B. Lubin, 1985) in differentiating anxiety, mood, and schizophrenic disorders was studied with 185 psychiatric patients and 185 matched comparisons. Results indicate that the MAACL-R is valid for both global and specific…

Suggests eight guidelines to help an analyst investigate whether rating-scale categories are cooperating to produce observations on which valid measurement can be based. Presents these guidelines in the context of Rasch analysis and illustrates their use. (SLD)

Explored the role of motion versus shape in children's categorization of animal and non-animal kinds. Found that 4-year olds significantly used motion cues over shape cues to categorize objects. Seven-year olds and adults tended to use motion more than shape to categorize animals but not geometric figures. Findings support view that children are…

Seven studies involving 256 undergraduates examined how people represent, access, and make inferences about the real-world category domain, foods. Results give a detailed picture of the use of cross-classification in a complex domain. (SLD)

Presents a reaction to Thompson and Neville's (1999) article, "Racism, Mental Health, and Mental Health Practice" and proposes that the unifying theme is categorization. Extends the concept of categorization, demonstrates it as the "lowest common denominator" of racism, and discusses the implications of categorization for…

Identifies the structure and composition of profile types most representative of the 2,200 children comprising the normative sample for the Wechsler Intelligence Scale for Children--Third Edition. Provides a case example using the method recommended for "everyday" decision making. (Author/MKA)

Examines the terminology used for "physical disability" in proto-Bantu and contemporary Bantu languages. Support for differing regional and historical meanings is developed, with the most ancient meaning linking physical disability to "becoming heavy" and contemporary Bantu emphasizing categorization in both human and non-human…
