Student ratings of teaching effectiveness are widely used to make judgments of faculty teaching performance. Research, however, has found that such ratings may not be accurate indicators of teaching performance because they are contaminated by course easiness. Using student ratings of 9855 professors employed at 79 different colleges and…

Recent studies linking marital status and health increasingly focus on marital trajectories to examine the relationship from a life course perspective. However, research has been slow to bridge the theoretical concept of a marital trajectory with its measurement. This study uses retrospective and prospective data to model the age-dependent effects…

The MMPI results obtained from 245 adolescent males referred to the evaluation unit of a Juvenile Court were submitted to a multivariate classification system. By correlating individual subject profiles with the modal profiles, six membership groups were formed. No relationship was found between group membership and age or race. (Author)

A sample of 9173 noninstitutionalized youth who took the 1980 Armed Services Vocational Aptitude Battery (ASVAB) was divided into five ability levels. Analysis supports the assertion that cognitive abilities are less correlated in higher ability groups and implies that greater classification effects can be associated with more intelligent groups.…

High point profile analysis of scores from the General Occupational Theme scale of the Strong Vocational Interest Blank-Strong Campbell Interest Inventory and the General Aptitude Test Battery for 516 males and 330 females indicated that interests correlated with high abilities. A theoretically coherent typology of individuals' vocational…

Three developmental connectionist models simulate a purported shift from "featural" to "correlational" processing in infant categorization (models: Gureckis & Love, 2004/this issue; Shultz & Cohen, 2004/this issue; Westermann & Mareschal, 2004/this issue; empirical data: Cohen & Arthur, 2003; Younger, 1985; Younger & Cohen, 1986). In this article,…

The view of a triad of impairments [(Wing and Gould (1979). "Journal of Autism and Developmental Disorders, 9," 11-30] in which impaired imagination is linked with repetitive behaviour is widely accepted. However this categorisation differs from the international classification systems, which link imagination to communication impairments rather…

This article analyzes the legal classification of Mexican Americans as "other white" as argued in a number of critical court cases that beginning in the 1930s up to the 1970s attempted to desegregate public schools in Texas. Since the Texas constitution declared school segregation as being only for "colored children," Mexican…

Initial progress has been made in the conceptualization and study of attachment stability over time, and substantial evidence has accumulated on the association between attachment classification and biopsychosocial functioning (including social-emotional competence, cognition, physical health and mental health). The literature supports the…

Model justified the expectation that the transfer from learning one task to another is linearly dependent on the coefficient of intercorrelation between the two studies when the coefficient was corrected for attenuation. Supportive studies are cited. Regression curves yielded negative intercepts. Testable explanations were offered. (Author/BJG)

To assess the effect on discriminant analysis in terms of correct classification into two groups, the following parameters were systematically altered using Monte Carlo techniques: sample sizes; proportions of one group to the other; number of independent variables; and covariance matrices. The pairing of the off diagonals (or covariances) with…

ONE OF THE PROBLEMS IN INFORMATION STORAGE AND RETRIEVAL SYSTEMS OF TECHNICAL DOCUMENTS IS THE INTERPRETATION OF WORDS USED TO INDEX DOCUMENTS. SEMANTIC TOOLS, DEFINED AS CHANNELS FOR THE COMMUNICATION OF WORD MEANINGS BETWEEN TECHNICAL EXPERTS, DOCUMENT INDEXERS, AND SEARCHERS, PROVIDE ONE METHOD OF DEALING WITH THE PROBLEM OF MULTIPLE…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

Three methods of transforming unordered categorical response variables are described: (1) analysis using dummy variables; (2) eigenanalysis of frequency patterns scaled relative to within-groups variance; (3) categorical variables analyzed separately with scale values generated so that the grouping variable and the categorical variable are…
