This article uses a nationally representative data set to determine the role of glass ceiling barriers and cohort effects on the earnings differences between women and men in an elite and growing group of professionals: Scientists and engineers. It draws on national data gathered in four surveys during the 1990s for cohorts graduating between 1955and1990.Results indicate a continuing pay gap net of human capital, family status, and occupational characteristics that was not fully explained by either cohort effects or the glass (...) ceiling. The authors suggest that the gender pay gap in these fields results from several unmeasured barriers that neither worsen across the life cycle nor become less problematic for recent cohorts. Improvements will require continued attention to discriminatory barriers. (shrink)

This paper presents a method for teaching undergraduate students how to write better term papers in philosophy. The method integrates two key assignment components: scaffolding and peer review. We explain these components and how they can be effectively combined within a single term paper assignment. We then present the results of our multi-year research study on the integrated method. Professor observations, quantitative measures, and qualitative feedback indicate that student writing improves when philosophy term paper assignments are designed to generate multiple (...) rounds of drafting and review.
