Discusses the relationship between changes in delinquency prevalence over time and prediction error. Data from a 21-year British longitudinal study exemplify the formal relationships that are derived. Results indicate statistically, as prevalence increases, a relative increase in false negative errors and a decrease in false positive errors…

Conducted a Monte Carlo computer simulation of the ANOVA design to detect job differences. The design proved reasonably powerful in detecting differences. A second study used Monte Carlo methods to analyze the viability of techniques for determining job differences. Offers guidelines for selecting statistical techniques. (Author/RC)

Presents the results of a study conducted to determine the allocation of general revenue sharing funds to libraries from 1973 through 1977 and to estimate the impact of these funds on library budgets around the country. Data are summarized in 6 tables and a reference list is included. (Author/JL)

Procedures for simultaneous confirmatory factor analysis in several populations are useful in a variety of problems. This is demonstrated with examples involving missing data, comparison of part correlations between groups, testing the equality of regression weights between groups with multiple indicators of each variable, and the formulation of…

Test data from two diverse culture groups were analyzed to determine the agreement among four methods of detecting item bias (transformed difficulty, discrimination differences, chi-square, and item characteristic curve). The test battery contained 155 items from six subtests: vocabulary, reading comprehension, mathematics, letter groups,…

With even the simplest bivariate regression, least-squares solutions are inappropriate unless one assumes a priori that reciprocal effects are absent, or at least implausible. While this discussion is limited to bivariate regression, the issues apply equally to multivariate regression, including stepwise regression. (Author/CTM)

Reviews research studies on note-taking and identifies possible questions for future research in that area. A case is made for the inclusion of such studies within the domain of educational technology research. A 49 item bibliography is attached. (MER)

Analyzes and compares the opinions of public library directors and ALA-accredited graduate library school directors on public library goals, probable library developments by the year 2000, and library performance measurements. The mean, median, mode, and interquartile range are indicated for each response. Included are six tables and six…

This study applied meta-analysis techniques to the gender studies cited by Maccoby and Jacklin and assessed the magnitude of cognitive gender differences. Results indicated that gender differences in verbal, quantitative, and visual-spatial ability were very small. (Author/APM)

Bogartz questions the Anderson and Cuneo study (p335-78 of this issue) on statistical-methodological grounds and on their positions concerning the concepts of conservation, centration, and compensation. (For Anderson and Cuneo's rejoinder to Bogartz, see p388-92 of this journal issue.) (SJL)

A comprehensive set of statistical data on the growth of faculty unionism is analyzed and various factors (such as the recent Yeshiva decision of the U.S. Supreme Court) that may alter future patterns of organization are discussed. (Author/MLW)

Suggests that dominance can be defined as asymmetry in predictability in social variables of importance, and bidirectionality as symmetrical predictability. Procedures which address the concepts of cyclicity within a person and synchronicity between people and which assess asymmetry and symmetry in social interaction are discussed. (Author/RH)

Determines the frequency distribution of Brainstem Auditory Evoked Potential variables (BAEP) for premature babies at different stages of development--normal newborns, infants, young children, and adults. The author concludes that the assumption of normality underlying most "standard" statistical analyses can be met for many BAEP…

Information is reported on state funds in support of public and private medical schools for the 1978-79 school year. The figures on public schools include breakdowns by state, distinguishing between funds provided directly to medical schools and funds provided through parent universities. (JMD)

Describes the experimental methods used to verify two hypotheses concerning the variability of linguistic behavior at the social and individual levels, within a homogeneous community. Postulates correlations among data from the social/individual "external dimension" and the "internal dimension" which is based on structural properties such as…
