A study was undertaken of the employment and enrollment patterns of women scientists/engineers and graduate students in eight major scientific fields: engineering, physical sciences, environmental sciences, mathematical sciences, agricultural and biological sciences, medical sciences, psychology, and social sciences. The first part of the study consisted of a series of statistical analyses of institutional and departmental patterns in women's full-time graduate enrollment and full-time employment in sciences and engineering in the 50 leading doctorate-granting institutions. The second phase consisted of case study site visits to a sample of nine institutions selected to represent the diversity of the original sample in geographic location, urban/rural environment, institutional size, type of control, and proportion of women scientists employed. The case study institutions were the University of Arizona, Harvard University, Louisiana State University (Baton Rouge), University of Michigan, Northwestern University, Purdue University, University of Southern California, Texas A & M University, and the University of Washington. The statistical analyses employed were designed to identify distinctive trends, to move beyond presentation of numbers and percentages to search for significant and distinctive differences. The report was exploratory and descriptive in nature, without specific research hypotheses. The analyses and results are described, with some graphic illustration. (Author/MSE)
