Hide Role Scoper Settings (Restrictions and Roles) for authors

I have installed role scoper plugin and after some fiddling have managed to give ‘authors’ the access to the only category I want them to post in (a group blog category).

As some of the new authors are not used to WordPress I’d like to keep the backend as simple as possible (only Post, Media and Comments).

I manged to hide everything but the Role Scoper settings of ‘Restrictions’ and ‘Roles’. My question is: Can I hide this too for all ‘authors’?

There is no need for it and it would be much better for my purposes to keep the backend very simple.

Thanks a lot for your help!
