A computer simulation compared significance tests of correlation coefficients calculated from initial scores, from ranks assigned by the Spearman method, and from three kinds of modified ranks. Implications of findings for the idea that rank correlation is a nonparametric correlation method are discussed. (SLD)

Presents a theoretical account of human shift learning with the use of neural network tools. Details how simulations using the cascade-correlation algorithm which show that networks can capture the regularities of the discrimination shift literature better than existing psychological theories. Suggests that human developmental differences in shift…

Proposes a procedure for generating multivariate nonnormal distributions. The procedure, an extension of the Fleishman power method (A. Fleishman, 1978), generates the average value of intercorrelations much closer to population parameters than competing procedures for skewed and heavy tailed distributions and small sample sizes. Reports Monte…

Discussion of self-report estimates of frequency and duration of computer use versus computer log data focuses on a study that compared self-report estimates and six months of electronic log data for health care workers using a new Community Services Information System. Correlations between the two types of data are reported. (Author/LRW)

Discussion of methodologies for online citation analysis focuses on a study of seven library-and-information-science journals that analyzed international characteristics on the basis of correlations between the geographical distribution patterns of authors, citations, and subscriptions. Also discusses Journal Impact Factor (JIF) as a measure of…

Analyzes the relationship between citation ranking and peer evaluation in assessing senior faculty research performance. Describes a study of faculty specializing in Kurdish studies that investigated to what degree citation ranking correlates with data from citation content analysis, book reviews, and peer ranking. (Contains 72 references.)…

Investigates the equality of "p" correlated effect sizes for "k" independent studies in which treatment and control groups are compared using Hotelling's "T" statistic. Illustrates the procedure and discusses the importance of sample size. (SLD)

Addresses two areas where science has been and still is used to justify policies and attitudes that are discriminatory and oppressive: homosexuality and alcoholism. This article analyzes the debate over whether these correlations are biologically or socially determined. Of particular concern is the potential impact of biological determinism on the…

Studies with 65 adults found two new visual processing tasks, visual change detection and visual movement detection, to be correlated with inspection time and the nonverbal scores from the Alice Helm 4 test of general intelligence. Results are discussed in terms of the correlation between inspection time and intelligence and the psychobiological…

Discusses a study of use of the Web-based virtual library at CISTI (Canada Institute for Scientific and Technical Information) by NRC (National Research Council of Canada). Results indicate that NRC staff is favorably inclined toward electronic resources and that a positive correlation exists between use of digital resources and perception and…

Strategies to avoid the penalties of extra variation described by J. Cornfield and reduced degrees of freedom in community-level trials were compared in Monte Carlo simulations. The three conditions necessary to ensure nominal Type I and Type II error rates are detailed. (SLD)

Administered the Stanford-Binet IV and the Wechsler Intelligence Scale for Children-III (WISC-III) to 31 subjects, ages 11-17 years, who were previously identified as functioning in the range of mild mental retardation. Correlations among scores on the tests were significant. The Stanford-Binet IV Composite IQ was higher than identified in the…

Attempted to relate content features of personality items to item parameter estimates from the partial credit model of E. Muraki (1990) by administering the Adjective Checklist (L. Goldberg, 1992) to 329 undergraduates. As predicted, the discrimination parameter was related to the item subtlety ratings of personality items but the level of word…

Studied the relationship between writing skills tested on a relatively brief standardized assessment and some nontest indicators of student writing ability. Results for 2,057 college students show modest correlations between writing assessment essays and the various nontest indicators, with performance on the assessment exhibiting the strongest…

Discussion of the relationship between child maltreatment and child disability identifies three categories: (1) maltreatment causes many disabilities; (2) children with disabilities are more vulnerable to maltreatment; and (3) other primary causal factors increase risk for both violence and disability. Maltreatment is also seen as impeding student…
