Type I error rates of four multivariate tests (Pilai-Bartlett trace, Johansen's test, James' first-order test, and James' second-order test) were compared for heterogeneous covariance matrices in 360 simulated experiments. The superior performance of Johansen's test and James' second-order test is discussed. (SLD)

Investigated group, grade, and gender differences in attitudes toward mathematics and science of gifted middle grades students (n=256) from three ethnic backgrounds. All groups exhibited positive attitudes. Significant group differences were found in students' perceptions of teachers' attitudes, mathematics anxiety, effectance motivation, and…

Used data from a time-diary survey of 2-parent, 2-child families (n=214) and single mother, 2-child families (n=99) to examine differences in how adolescents use their productive time in the following domains: (1) housework; (2) school work; and (3) paid employment. Adolescents' age and mothers' education and employment influenced time allocation…

Discusses the use of multimedia to facilitate learning processes; reviews research that addresses specific effects of media; and describes studies of high school students that tested the influence of video, photography, and individualized testing on acceptance and recall of information provided by a multimedia encyclopedia about professions and…

Hypothetical teacher candidates were created, some of whom were depicted as having an acknowledged disability, others having no acknowledged disability and all varied with respect to chronological age. A national random sample of public school principals evaluated the teacher candidates as if screening for a vacant position within their school…

Previous research has shown community violence to be detrimental to adolescent well-being, yet relatively little is known about how adolescents respond to violence in their community. Using data from the National Longitudinal Study of Adolescent Health, this study examines the interactive associations among exposure to street violence, adolescent…

Bivariate and multivariate correlation analyses were used to investigate personality trait variables and their relation to DSM-IV symptomology in a clinically-identified sample of 142 Mexican-American adolescents. Personality variables were measured with the Personality Style subscales of the Millon Adolescent Clinical Inventory. DSM-IV…

Multivariate statistical analyses were used to determine if there were differences in social community, learning community, and perceived learning between male and female students in 12 online graduate education courses in which female students (n = 162) outnumbered males (n = 31). Study results provided evidence that females felt more connected…

Five experiments are reported in which the picture naming performance of bilingual speakers in a language-switching task was explored. In Experiment 1, Spanish learners of Catalan and Korean learners of Spanish were asked to perform a switching task between their first and dominant language (L1, Spanish or Korean) and their second language (L2,…

This study investigated the effect of phonological sensitivity of two comparable groups of grades 4 and 5 Chinese children, one a Putonghua-speaking group ("n" = 77) from Beijing and the other a Cantonese-speaking group ("n" = 80) from Hong Kong on English and Chinese pseudoword reading. It was hypothesized that the Beijing…

Establishing stability, defined as observing minimal measurement error in a test-retest assessment, is vital to validating psychometric tools. Correlational methods, such as Pearson product-moment, intraclass, and kappa are tests of association or consistency, whereas stability or reproducibility (regarded here as synonymous) assesses the…

This study used cluster analysis to identify college orientation profiles of 115 Latino college freshmen from lower socioeconomic status backgrounds and examined the relationship of profiles to adjustment and academic outcomes. Participants were surveyed on personal and cultural types of motivation and college degree goals, degree confidence, and…

The aim of this paper is double. First, it provides a conceptual framework linking human resource management, organisational learning and knowledge management. Second, the paper builds a causal model and tests it with a sample of firms from the Spanish manufacturing industry, using a structural equation modelling technique. In particular, after…

This exploratory study examined the range of gender-based achievement motivation patterns evident in a group of Australian final year high school students. Single, dual and multiple goal complexes were compared, enabling an evaluation of the relative impact of each of the goals on these patterns, as well as their relationships with academic…

Colleges and state higher education agencies too often lack accurate information about the socioeconomic status (SES) of their students. This paper describes the methodology that Community College Research Center (CCRC) researchers used to estimate the SES of individual students in the Washington State community and technical college system using…
