1) Reduce competition. Make jobs less desirable to where there might be able to win without cheating. More people at lower salaries would be good here. More research/teaching gets done, and you eliminate subclasses like adjuncts and lifelong postdocs.

2) Ban universities which take federal grants, federal student aid, 501(c)3 status, etc. from using NDA/non-disparage agreements.

3) Put in FOIA/public records-style transparency measures.

4) Open science / open data. Publications should be open too, as should source code. Anyone should be able to replicate scientific research unless it requires $$$ equipment or e.g. builds on personally-identifiable information.

5) Democratic governance processes within universities and salary caps (it doesn't get at this stuff, but it does at a lot of embezzlement).

6) Limit number of grad students per advisor.

Basically, let enough sunshine in that the bad stuff can't stick around.
