Focuses on the interpretation of research data of Berthier, Starkstein, Lylyk, and Leiguarda (1990) reporting a case of faster recovery, after selective sodium amytal injection, of the patient's second language than his native language. Paradis (1990) argued that these results do not support Ojemann and Whitaker's (1978) hypothesis. (five…

Introduces a new concept and technique for information retrieval called colinked descriptors. Highlights include bibliometrics and information retrieval, cited references and linked thesaurus terms, cocited references, examples of colinked descriptors in the "Thesaurus of ERIC Descriptors," and experiments that tested the colinked…

Studied conditions conducive to conceptual growth and those conducive to procedural growth in student hypothesis testing in science by studying 216 Scottish elementary school students. Results suggest that problems can be overcome when students debate their conceptual knowledge and reach consensus and subject their consensual positions to…

Used simulation to compare structural equation modeling methods for estimating and testing hypotheses about an interaction between continuous variables. Findings indicate that the two-stage least squares procedure exhibited more bias and lower power than the other methods. The Jaccard-Wan procedure (J. Jaccard and C. Wan, 1995) and maximum…

Demonstrates the use of simulation systems for studying diagnostic problem solving and presents results from two empirical studies in which undergraduates diagnosed faults that occurred in a computer-based, dynamic simulation. Discusses dual problem space search that includes generating and testing hypotheses; suggests implications for designing…

Makes the case that hierarchical linear models or longitudinal multilevel models are a better alternative than standard regression models for empirical tests of predictive developmental hypotheses. Describes a multivariate longitudinal model linking developmental data to a criterion and presents an example from a study of the prediction of infant…

Two studies were carried out during university workshops, and analyzed the effects of resource interdependence on student-student interactions, and the impact of these interactions on performance. Students worked cooperatively, either on complementary information (positive resource interdependence) or on identical information (resource…

The scarce attention to the assessment and evaluation in science education research has been especially harmful for teaching science-technology-society (STS) issues, due to the dialectical, tentative, value-laden, and polemic nature of most STS topics. This paper tackles the methodological difficulties of the instruments that monitor views related…

The study examined the application of 1:3 in employments of academic and non-academic staff in Nigerian Universities, as recommended by the National Universities Commission (N.U.C.), following the general feeling that Nigerian Universities were highly bureaucratised; non-teaching staff was over employed while some universities lacked…

Grounded in the theory of ambivalent sexism, this study tested the speculation that women's benevolent sexist attitudes may be, in part, a self-protective response to environments they perceive as hostile to women. Data that have indirectly supported this conjecture thus far have been correlational. The current study involved a more powerful,…

It is often of interest to estimate partial or semipartial correlation coefficients as indexes of the linear association between 2 variables after partialing one or both for the influence of covariates. Squaring these coefficients expresses the proportion of variance in 1 variable explained by the other variable after controlling for covariates.…

This article investigates the effect of inconsistency between parental marital conflict and disruption on children's health. Inconsistent situations arise when minimal marital conflict precedes disruption or when marital conflict is high but there is no disruption. Using data from the National Longitudinal Survey of Youth, two alternative…

For two random variables, X and Y, let D = X - Y, and let theta[subscript x], theta[subscript y], and theta[subscript d] be the corresponding medians. It is known that the Wilcoxon-Mann-Whitney test and its modern extensions do not test H[subscript o] : theta[subscript x] = theta[subscript y], but rather, they test H[subscript o] : theta[subscript…

Historically, males have almost exclusively controlled sport (Cashmore, 2000). While this control has been evident on the playing field (Sage, 1998) and in the media's coverage of sport (Kinkema & Harris, 1998), it has also been prevalent in all levels of administration positions in sport (Coakley, 2001). In intercollegiate athletics, the…

This study examines the prevalence, stability, and development of physical aggression, as reported by mothers and fathers, in a sample of children initially recruited at 12, 24, and 36 months (N=2,253) and in a subsample followed up 1 year later (n=271) in a cross-sequential design. Physical aggression occurred in 12-month-olds, but significantly…
