The May '08 issue of the Journal of Applied Psychology is out with lots of great content. Unfortunately only one is directly related to recruitment and assessment, so let's check that one out then I'll give you links to some others that look interesting.
The study is Ethnic and gender subgroup differences in assessment center ratings: A meta-analysis by Dean, Roth, and Bobko. The authors found overall d-values of .52 for Black-White differences, .28 for Hispanic-White differences, and -.19 for male-female differences. (the second group in these comparisons performs better)
The results suggest that the Black-White difference is larger than previously thought but may be a more "diversity friendly" option for Hispanics and females.
There are some other great articles in here for fans of organizational behavior, including:
Subjective cognitive effort: A model of states, traits, and time. (which, by the way, suggests another reason why conscientiousness may predict job performance)
Early predictors of job burnout and engagement.
Event justice perceptions and employees' reactions: Perceptions of social entity justice as a moderator.
Harmful help: The costs of backing-up behavior in teams.
Trust that binds: The impact of collective felt trust on organizational performance.
