Michael:
As far as I can tell, none of those deal directly with the circumstances Joughin faced.
And again you are misconstruing my remarks, my belief is simply that Joughin encountered special circumstances that night which allowed him to survive while so many others who faced the same thing it did, and it could possibly all come back to be linked in some way to the consumption of alcohol.
That theory doesn't really need to be accurate as to the amount that he drunk, but simply that he DID drink, whereas an accurate scientific analysis would have to be based on exact amounts, what kind, how quickly it was drunk, etc etc in order to be believable.
If the story in the first place isn't reliable or accurate, then neither can the science be that tries to solve it.
Cheers,
Adam.
