Presents a two-part analysis of the note on Proposition 20. Findings suggest that environmental concern may be more broadly distributed across different socioeconomic and political strata of our society than previous investigators have asserted. (Author/MA)

The authors examine the special educator's plight in translating laboratory findings into classroom practice, in terms of the possible ungeneralizability of the experimental outcomes. (Author/PHR)

A two-year study of learning disabilities found in association with French immersion programs indicates that children encountering difficulty in primary French immersion programs have a specific learning disability characterized by a pattern suggesting a maturational lag in the temporal lobe regions of the brain. (JMF)

Presents in full the questionnaire sent to member institutions of the American Society for Engineering Education to collect data on engineering education and research for the school year 1975-76. (MLH)

Investigates the discriminant validity of a measure of attitudes toward male roles, the Male Role Attitude Scale, using data from the 1988 National Survey of Adolescent Males. Results support the argument that attitudes toward male roles are conceptually different from other gender-related attitudes. (SLD)

Examines assumptions underlying the employment of group means in communication research. Suggests a sample mean cannot be assumed to be a "good" statistic when the response vector represents different individuals' outcomes versus different outcomes of an individual. Notes implications for communication research. (SR)

Statistical studies often show public opinion strongly affecting public policy. But the studies may overestimate the effect because they focus on issues--those especially important to the public--on which governments are most likely to be responsive. This article considers what the opinion-policy linkage would be if less-important issues were also…

Compelling arguments for reform of statistical practices have been made in many disciplines, in some cases over several decades, but achieving reform has proved difficult. We discuss how reform has progressed--or not progressed--in psychology, medicine, and ecology and describe case studies of attempts by pioneering journal editors to change…

The paper is a critique of the traditional mode of interpreting factor analyses; it is not a criticism of factor analysis per se. Instead, the author proposes a statistical procedure based upon stepwise regression (SRP). The traditional mode focuses on the largest factor loadings (FL). A factor is both described and named by these heavily weighted…

Discusses the format, grading procedures, and student reaction to two undergraduate engineering courses taught by programed instruction. Statistical analysis shows that the programed instruction resulted in higher and more uniform student achievement than did the conventional instruction in the same subject area. (MLH)

A 1971 study of formation of language attitudes and their basis, and in particular the concept of "best" language variety, among predominantly immigrant Mexican-American parents is reported. (RM)

Use of English expressions in Israeli universities is discussed. A study among Israeli psychologists inquiring into the relative weight of variables associated with the use of Hebrew versus non-Hebrew terms is reported. (RM)

Each of the four classic multivariate analysis of variance (MANOVA) tests of statistical significance may lead a researcher to different decisions as to whether a null hypothesis should be rejected: (1) Wilks' lambda; (2) Lawley-Hotelling trace criterion; (3) Roy's greatest characteristic root criterion; and (4) Pillai's trace criterion. These…

Most currently used measures of inter-rater agreement for the nominal case incorporate a correction for "chance agreement." The definition of chance agreement is not the same for all coefficients, however. Three chance-corrected coefficients are Cohen's Kappa; Scott's Pi; and the S index of Bennett, Goldstein, and Alpert, which has…

The Auto-Regressive Integrated Moving Average (ARIMA) Models, often referred to as Box-Jenkins models, are regression methods for analyzing sequential dependent observations with large amounts of data. The Box-Jenkins approach, a three-stage procedure consisting of identification, estimation and diagnosis, was used to select the most appropriate…
