To find a method for making better use of vocational interests in occupational guidance, Roe's occupational classification system was tested. A search was made to determine whether this system would yield a contiguity structure of occupations, by interests, showing the relationships between interests in different types of occupations. Three…

Although relational demographers have based their arguments on self-categorization theory, they have paid little attention to the underlying processes associated with this theory. The authors examined whether demographic dissimilarity affects individuals' identification with groups by affecting the group's prototype valence and clarity and the…

Measures of clinical significance are frequently used to evaluate client change during therapy. Several alternatives to the original method devised by N. S. Jacobson, W. C. Follette, & D. Revenstorf (1984) have been proposed, each purporting to increase accuracy. However, researchers have had little systematic guidance in choosing among…

Although the primary use of the speaking section of the Test of English as a Foreign Language™ Internet-based test (TOEFL® iBT Speaking test) is to inform admissions decisions at English medium universities, it may also be useful as an initial screening measure for international teaching assistants (ITAs). This study provides criterion-related…

Experiments were performed to determine the feasibility of using ALCAPP as one form of on-line dialogue. Assuming the ALCAPP (Automatic List Classification and Profile Production) system is in an on-line mode, investigations of those parameters which could affect its stability and reliability were conducted. Fifty-two full test documents were used…

Eleven indexes of rurality and their effect on the classification of Michigan's 83 counties were investigated. The indexes were based on different concepts of rurality: (1) percent of employment in agriculture, fishing, and forestry; (2) population density and distance to urban centers; and (3) economic conditions. Index rankings were compared to…

This report was prepared by the Careers and Curricula Program, which is a career development and guidance program sponsored by The Center for Social Organization of Schools. As one of five Center programs which develop scientific knowledge of the schools' effects upon students and utilize this information to improve educational practices, this…

The purpose of this paper is to suggest a technique of cluster analysis which is similar in aim to the Interactive Intercolumnar Correlation Analysis (IICA), though different in detail. Two methods are proposed for extracting a single bipolar factor (a "contrast compenent") directly from the initial similarities matrix. The advantages of this…

A detailed description of the Staff Sentiment Scale (SSS) is given. In addition, a brief description of the Conceptual Model, upon which the SSS is based, is given. The model is based on an extensive review of the literature of organizational theory and differentiated staffing and upon systematic observations in schools. It treats Process…

Distinctions were made between three classes of statistical linkage: equivalence, concordance, and prediction. These distinctions were based on rational content considerations and empirical statistical relationships. A large database involving SAT I and ACT scores was used to determine which type of linkage was best suited for different scores and…

Reports on research that examined the clustering of similar books provided by a classification system and ways in which the books that patrons circulate are clustered in a university library. Measures of classification system performance are suggested and used to evaluate two test collections. Consequences for full-text document systems and online…

This study examined relationships between group climate (participants' learning orientation, feelings of psychological safety, and self-disclosure), process (feedback and conflict), and performance in continuous quality improvement groups. Forty-nine participants in eight hospital groups were surveyed as the groups neared completion. Groups were…

The author investigated the relation between gender-role classifications and prosocial and antisocial behavior for 505 Chinese adolescents in grades 7 to 12. The author found that (a) boys were more antisocial than girls were, (b) there was no significant gender difference in prosocial behavior, (c) prosocial behavior was associated positively…

This study compares the classification accuracy of linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), logistic regression (LR), and classification and regression trees (CART) under a variety of data conditions. Past research has generally found comparable performance of LDA and LR, with relatively less research on QDA and…

The types of gesture+speech combinations children produce during the early stages of language development change over time. This change, in turn, predicts the onset of two-word speech and thus might reflect a cognitive transition that the child is undergoing. An alternative, however, is that the change merely reflects changes in the types of…
