THE PERSON LESS ABLE TO CONTROL HIS IMPULSES IS ALSO APT TO EXHIBIT SOCIALLY DISVALUED BEHAVIOR. VOCATIONAL AND ACADEMIC FAILURE IS A PARTIAL CONSEQUENCE OF IMPULSIVENESS AND LACK OF SELF-CONTROL. TO INVESTIGATE IMPULSE CONTROL, TWO INSTRUMENTS BELIEVED TO MEASURE ATTRIBUTES OF OPPOSITE POLES OF THIS CONCEPT (SEQUENTIAL TESTS OF EDUCATIONAL…

When the school or district is the unit of analysis in school effects research, the outcome of interest is mean achievement, and the variance explained by school or district level predictors is between schools or between districts. When the individual is the unit of analysis, the outcome of interest is individual achievement and the variance…

Explores the impact of budget changes on the intensity of program services received by students in federal compensatory education programs under Chapter 1 of the Education Consolidation and Improvement Act (1981). Results show that moderate budget cuts translated into service intensity declines, implying that Gramm-Rudman impacts could be worse.…

Gifted and highly gifted girls in grades four to six were given Piagetian-type manipulative problem-solving tasks reflecting formal operations. Although Flavell suggested that a chronological age of 10 years was necessary for successful completion of these tasks, time allowed was a more valid predictor. (LMO)

Male and female junior high school students were administered the recently published Computer Aptitude, Literacy, and Interest Profile, and their composite scores were compared to cumulative mathematics subscales of the Stanford Achievement Test, Advanced Form E. Results showed that mathematics achievement was significantly associated with…

Ridge estimates (REs) of population beta weights were compared to ordinary least squares (OLS) estimates through computer simulation to evaluate the use of REs in explanatory research. With fixed predictors, there was some question of the consistency of ridge regression, but with random predictors, REs were superior to OLS. (SLD)

Describes: (l) a microcomputer-based system for filing test questions and assembling examinations; (2) microcomputer use in practical and simulated experiments of gamma rays scattering by outer shell electrons; (3) an interactive, screen-oriented, general linear regression program; and (4) graphics drill and game programs for benzene synthesis.…

Two approaches are used to assess the one-month stability of depression affect in college students: (1) a high retest correlation is demonstrated for a latent depressive affect construct using self-reports from the previous month; and (2) predictive validity of depressive categorization is examined using logistic regression techniques.

There is a unity underlying the diversity of models for the analysis of multivariate data. Essentially, they constitute a family of models, most generally nonlinear, for structural/functional relations between variables drawn from a behavior domain. (Author)

A statistical model is proposed for both contextual analysis and slopes as outcomes analysis. A random coefficient model is investigated in detail. Various estimation models are reviewed and applied to a Dutch school-career example. (Author/LMO)

This paper extends Minar's (1974) semilog wage regression method to include those who interrupted their schooling with years of work. Schooling and the duration of the interruption interact to create nonlinearities in the rate of return to schooling. The method is applied to Vietnam era G.I. students and civilian interrupters.

Teachers' ratings of academic ability in mathematics; and English were regressed on test scores in a sample of second-grade Irish students. Within the terms of the model, teachers' ratings were only marginally less defensible than ratings based on a previous administration of the same tests. (Author/DWH)

The number of regression studies being employed in sex discrimination cases is increasing. The need for caution in the case of multiple regression must be emphasized. Statistical concerns in sex discrimination cases are highlighted. (MLW)

Work of students identified as basic writers was studied and analyzed to determine students' perceptions about composition. Results suggest that progress is linked to the ability to develop and elaborate ideas while writing, to the ability to generate acceptable English automatically, and to the ability to rewrite, edit, and revise. (Author/LMO)

Social impact of a videotex system developed for farm operators is assessed by examining whose needs the system served; who were early adopters; and who most used and benefited from the system. This assessment demonstrates importance of tracing out each phase of the process by which information inequities are created. (Author/MBR)
