Postdoctoral appointments can have different functions and meanings, depending on the field and whether the postdoc is a man or a woman. The Ph.D.'s-Ten Years Later study confirmed that in biochemistry, the postdoc, not the Ph.D., has become the general proving ground for excellence both in academia and industry. Because they spent a longer time in these "mandatory" postdocs, biochemists had the largest proportion of untenured faculty 10 to 13 years after the Ph. D. In mathematics, where substantially fewer postdoctoral positions are available, Ph.D.'s taking postdocs are more likely to obtain faculty positions, but this is true only for men. University administrators should be accountable for monitoring the total time spent in these positions and should provide administrative assistance for skills training, career growth, and the job search. In addition, creative solutions concerning the dual-career couple phenomenon are necessary.

Data obtained with semiconductor detectors and a particle-identifier system on fragments ejected from uranium bombarded with 5.3-GeV protons show that ^Li, 14 B, and 15 B are particle stable, 10 Li is particle unstable, and 13 Be is most probably particle unstable .

How the University of California at Berkeley's graduate division has used quantitative analysis and qualitative methods to address the issues of time to doctoral degree and student retention is described. The graduate division used this research to develop recommendations and design programmatic outreach activities to improve graduate education.
