Reports that students with soil science background performed better on a diagnostic examination; no relationship existed between exam performance and country of origin, degree sought, or undergraduate class quartile. Concludes that exam results, the grade received in a beginning graduate-level course and the cumulative graduate grade-point average…

Discusses the issue of who will do science in the future. Reports on several graduate student surveys that concluded that women were indistinguishable from men in objective measures of preparation, career aspirations, and performance in graduate school. They differed significantly in their perceptions of preparation, pressures and coping…
