Analysis of the pairwise preferences of pairs of gambling stimuli elicited from each of 40 chronic schizophrenic inpatients, 32 schizophrenic outpatients, and 33 siblings or parents of these patients indicates that choice behavior was usually determined by the expected value of the stimuli, with no significant differences among groups.

Three methods for grouping items in an opinion survey were compared for their utility in subscale construction: rational organization according to content, factor analysis, and multidimensional scaling. Only subscales based on factor analysis could be refined to meet the criteria of reliability, additivity, and interpretability simultaneously. (SV)

The current state of multidimensional scaling using the city-block metric is reviewed, with attention to (1) substantive and theoretical issues; (2) recent algorithmic developments and their implications for analysis; (3) isometries with other metrics; (4) links to graph-theoretic models; and (5) prospects for future development. (SLD)

Strong Interest Inventory scores of 103 female and 73 male Native American college students were submitted to multidimensional scaling analysis. Results supported the circular order and two-dimensional relationship of career interests. Females' results were more consistent with Holland's hexagonal model than were males' scores. (SK)

Examines university employees' (N=130) awareness and perceptions of the importance of university counseling and consultation services. Results indicate that employees fell into 1 of 4 groups sharing similar perceptions of counseling and consultation activities. Implications for service provision and research are discussed.

The valid provision of subscores from an item response theory-based test implies a multidimensional test structure. Assuming, in the construction of a new test, that the test features required for a valid and reliable total test score have been specified already, this article describes the resulting subscore performance and the resulting…

Many statistical models have been used to study human development. The multidimensional scaling (MDS) method has been an under-utilised technique in psychological and educational research for studying such phenomena. In this paper, MDS profile analysis was used to examine adolescent mood change patterns over a 1-week period. This method is used to…

This study examines how mathematics and science teachers' classroom assessment practices were affected by the National Board Certification process. Using a 3-year, longitudinal, comparison group design, evidence of changes in teachers' classroom practice were measured on six dimensions of formative assessment. The National Board candidates began…

This paper begins by reviewing some of the different models of third-party observation of university teaching that can be found in the literature. Having analysed these, it argues that--if "peer" is taken to indicate equality of status--only one is genuinely a model of peer-observation. It proposes an alternative categorisation of third-party…

The Program of Systematic Evaluation (PSE), which began as an attempt to explore the instructional dimensions of multimedia, has evolved into the most comprehensive set of experimental multimedia studies exploring the varied dimensions of cognitive load theory as they relate to the design of effective and efficient visual learning environments for…

This article traces the roots of narrative research in the social sciences and education, then centers on "story constellations," a version of narrative inquiry that uncovers teachers' knowledge of school reform in context. A fluid form of investigation that unfolds in a three-dimensional inquiry space, story constellations consists of a flexible…

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both…

The assumption that people possess a repertoire of strategies to solve the inference problems they face has been raised repeatedly. However, a computational model specifying how people select strategies from their repertoire is still lacking. The proposed strategy selection learning (SSL) theory predicts a strategy selection process on the basis…

Although some research has examined the factorial nature of the Multidimensional Aptitude Battery (MAB), none has tested hypotheses relevant to both oblique and orthogonal models via confirmatory factor analysis. Thus, in this investigation, a series of models was tested, which compared the model fit of both oblique/higher order models against a…

Certain definitions introduce appropriate concepts, among which are the definitions of the counting functions of the primes and twin primes, along with definitions of the correlation coefficient in a bivariate sample space. It is argued conjecturally that the characteristic functions of the prime "p" and of the quantity "p"+2 are highly…
