Statistical data are presented to answer the question, "Why do women work?" and to give highlights of women's employment and education in the years 1972-73, compared to the past. Women's Bureau publications are listed, with instructions for ordering. Also, the myth and the reality of women in the workforce are contrasted. (AJ)

Simplicity and flexibility of the full rank linear model motivated this paper which introduces researchers to the theory necessary to understand the model and apply the theory in the analysis of some standard fixed effects experimental designs. The theory and examples should help researchers use the model as an experimental tool and a model for…

From a series of studies financed under a grant of the Rockefeller Foundation for work in the area of production functions and income distributions.

To estimate the influence of positive reinforcement on classroom learning, the authors analyzed statistical data from 39 studies spanning the years 1958-1978 and containing a combined sample of 4,842 students in 202 classes. Twenty-nine characteristics of each study's sample, methodology, and reliability were coded to measure their effects on…

The leadership substitutes hypothesis has been used to explain the occasional successes and frequent failures of leadership predictions. Three hypotheses were formulated to test the viability of the leadership substitutes concepts. Questionnaires were administered to hospital managers (N=63) and engineers (N=71). Instrumental and supportive leader…

Previous researchers, notably James Coleman, found that schools had very weak effects on student achievement and that socioeconomic factors had very strong effects. They made this discovery by measuring the effects of schools when socioeconomic factors were held constant, and they found negligible effects of schools. This study's hypotheses are…

Three procedures used to control Type I error rate in stepwise regression analysis are forward selection, backward elimination, and true stepwise. In the forward selection method, a model of the dependent variable is formed by choosing the single best predictor; then the second predictor which makes the strongest contribution to the prediction of…

This study was undertaken to determine the effects of individualized instruction on enrollment, attrition, achievement, and student attitude in a general biology course for non-science majors. Fifteen auto-tutorial minicourses were designed for use in the laboratory part of the course, each consisting of a printed study guide, slide-tape module,…

Although New York State's provisions for funding public education are among the best in the nation, improvements are needed in the state aid program. In this study, school district data on expenditures and wealth were analyzed and evaluated. Two direct causes of the substantial inequalities among school district services in New York are the…

The major advantage of sequential classification, a technique for automatically classifying documents into previously selected categories, is that the entire document need not be processed before it is classified. This method assumes the availability of a priori categories, a selection of keywords representative of these categories, and the a…

After training and a pilot test, 19 groups throughout the United States composed of a total of 187 monitors--predominantly women--were evaluated on the basis of sex role criteria programs telecast on the three commercial television networks during a 12-week period from November 1975 through February 1976. Results indicated that the 1975-76…

This Masters Thesis from the Ohio State University examines the trend in coverage of environmental problems in two newspapers from 1962-1977. Data were gathered by analyzing the content of the "Chicago Tribune" and "New York Times." Environmental stories from 24 selected issues per year were coded and analyzed using the…

Knowledge of the magnitude of effect(s) of an experimental study in science education should be of utmost concern to researchers in the field, but is often not reported. This document describes the concept of "explained variance" in analysis of variance designs and then explains how it can be calculated and reported. Reporting the magnitude of…

A cost analysis of the problem of growing library collections shows that it is more desirable, economically and academically, to establish regional compact shelving facilities for infrequently used library materials than to discard the materials. This report develops and applies a cost model--based on the Palmour Cost Model--which examines the…
