Commentary on ‘mentoring and the impact of the research climate’

First of all, I would like to commend Roberts and colleagues for taking on a difficult but very important topic. It would be valuable if someone could follow up with a broader sample of universities and laboratories -- paying careful attention to possible sampling and non-sampling errors. In general, I recommend that mentors explicitly both learn and teach ethical theory and practice within the context of their scientist development programs. Finally, while it is important to emphasize sound and ethical research standards and processes in mentoring programs, this should not be at the expense of an appropriate emphasis on skills essential to professional competitiveness, such as responsible, effective publication, grant winning, and demonstrably strong performance on the grants won.[PUBLICATION ABSTRACT]
