Students can't either. Administrators can to some extent, but their power to command faculty and students is limited. Alternative forms of action include incentives and political action. Incentives are important but also limited at a time of tight money. Nevertheless, we should devote more attention to them.
Political action is the neglected stepsister.
It can be highly effective in a university because there is a general disposition in favor of diversity. We don't discuss political action very often because most of us don't know what to do about it. But it does seem reasonable to think that useful initiatives could be undertaken to educate and empower those interested on the subjects of incentives and political action. Otherwise we are doomed to continuing disappointments caused by the limited efficacy of punishments.
