Circulated library books classified according to academic subject areas and student majors were used to determine relative subject similarities in 40 academic departments. Use of multidimensional scaling to compute similarities in undergraduate and graduate circulation and implications for library collection development and storage are described.…

Reviews visualization techniques for scientific disciplines and information retrieval and classification. Highlights include historical background of scientometrics, bibliometrics, and citation analysis; map generation; process flow of visualizing knowledge domains; measures and similarity calculations; vector space model; factor analysis;…

Examines the students' understanding of mathematical structure and the relationship between problem solving and the identification of the structure in 13 word problems. Multidimensional scaling and hierarchical cluster analysis were used to assess how subjects organized word problems in their minds. (YP)

Explores the intellectual subject structure and research themes in software engineering through the identification and analysis of a core journal literature via two expert perspectives: the author, through cocitation analysis; and the indexer, through subject terms selected to facilitate retrieval. Topics include cluster analysis, multidimensional…

Although some researchers have argued against use of the term "content validity," the ability of a test item to adequately represent the domain of knowledge tested continues to be an issue of paramount importance in test construction. The present paper reviews previous analyses of test content and proposes a new empirical method for…

A few multi-dimensional items were found to be more efficient than a larger number of uni-dimensional items in tests for participant selection and evaluation of such compensatory educational programs as Title I. A multi-dimensional scaling technique is described which derives scores for each item on three dimensions, and allows multiple scores to…

This study is an attempt to model the similarities of 84 medical schools with respect to their orientations toward applicants qualified for research and applicants interested in delivering primary care or locating in non-urban settings. These characteristics are defined in 17 institutional variables. The patterns of insti(utional similarity are…

In recent years, there has been increasing interest in finding ways of promoting and evaluating structural knowledge (knowledge of how ideas, events, and principles are interrelated). Research has demonstrated that students' numerical judgments of the strength of relatedness among ideas drawn from a domain provide insights into how they have…

A comparison was made of responses to two types of personality inventory items, either sentence-type items or adjective-type items. Three methods of analysis were applied. It was concluded that the two item types give approximately equal results. (CTM)

Examined perceived antecedents of sex and preferred partner qualities in African-American and White late adolescents. Found that African Americans mentioned "nice body" as criterion for partner attractiveness; Whites did not. Males identified sexual arousal as a reason for sex; females did not. African-American males associated sexual…

Multidimensional scaling and cluster analysis were used to describe and categorize tasks from six graduate disciplines including academic psychology, applied psychology, English literature, journalism, physics, and electrical engineering. A sample of task descriptions was constructed through interviews with four or five graduate students from each…

A sociometric survey examined the informal faculty development network existing within the School of Nursing at East Tennessee State University. During the fall 1983 semester, all 25 nursing faculty members at the school were asked to complete a self-report instrument dealing with patterns of seeking and providing advice regarding their role as a…

One of the major assumptions of latent trait theory is that the items in a test measure a single dimension. This report describes an investigation of procedures for forming a set of items that meet this assumption. Factor analysis, nonmetric multidimensional scaling, cluster analysis and latent trait analysis were applied to simulated and real…

This study investigated (1) relationships between reading comprehension, IQ, and equivalence range (ER) and (2) categorizing styles through multidimensional scaling and varimax rotation analysis. One hundred and six male and 97 female sixth-graders comprised three reading groups according to Metropolitan Achievement Test, Reading subtest, and Otis…

Indicates that membership in pausing and skimming clusters appears to relate to text comprehension, grade level, and rated academic ability, but that these relationships are not all simple or direct. Finds that the cluster-analytic approach provides a useful empirical adjunct to current theoretical perspectives on text analysis and reading…
