I've tried to avoid participating in this thread. Honest. But I am too weak.

With all due respect, I think you are asking the wrong question.

Better questions might be ones along the lines of:
Do competitions affect traditional Folk Arts?
How exactly do competitions affect them?

Your question is not a question about empirically observable changes. It is a question that assumes changes and then places a value judgment on them.

If I were to see a dissertation based on the question as it currently exists I would expect to learn a lot about YOUR evaluation of a phenomenon. I probably wouldn't read it.
I would probably read a dissertation based on the other questions. I'd then feel free to make my own judgment of the phenomenon.
