Researching programming language security

For my dissertation I am starting out researching programming language security. So far I have looked at Perl, Ruby, FreeBSD jail, and now I am looking at Java. Planning to also look at .NET, Lua, C#, Sing#, Tcl, and of course JavaScript.

I was wondering if anyone out there had specific research papers out there on programming language security (or anything related) that they would recommend I read? I obviously want to come up with a good security model for Python (initially for embedding, but hopefully generic enough to expand out to not just for embedding) and so I am trying to do my homework first.
