Staff management issues

Why can't people see that a student publication should be run similar to a business? It's odd, I've told my staff that if people are to take us seriously, we need to act seriously. For whatever reason, though, the staff, more specifically the Editorial Board doesn't seem to get that.

I was curious if any other staffs have experienced this problem, and what they've done to alleviate it. I know that, short of screaming at them, I'm out of ideas.
