There is a lot of corporate "W" speak out there... we use a lot of the same words in research; unlike in corporate, we like to think (and I certainly try to) we use those words as carefully as possible, not because we are trying to cover something up!
It's odd how sometimes you have to be careful in what you say and sometimes select the right words. My biggest experience of this was writing emails, of all things. Depending on who you were talking to, and what you wanted out of the exchange, you had to get the right words, the right language and the right length of text. Sometimes you use big words and sometimes you didn't. It would do your head in sometimes when you reckoned up the amount of time required just to knock up an email and a proposal.
In my opinion, W words are often conceived with better intentions, but due to their inconsistency with their practice in real life, they slowly but surely have fallen into disrepute.
"Contextualisation" wouldn't have too many uses. Might save some space on a flow diagram, but simply saying "establish context" or similar in place doesn't use too many more characters and is more descriptive.
As for the criminal behaviour thing, I don't quite get that either, although at least these days "paedophile" is already deep enough in terms of having a negative connotation - doesn't matter if you're a "paedophile" or "child molester", either way you're as good as dead to many people! To put an alternative spin on things, if someone was falsely accused as being such a person (and it has been known to happen, unfortunately), until they were to clear their name, I don't think living with either "paedophile" or "child molester" as a title will really do much for their well-being.
I've never heard of "shrinkage" in place of theft - theft is theft - pretty basic - and I'm not sure what it should be named either way or that, except perhaps the not-so-different "robbery". I believe in the Old English days, theft was bundled in with the broad range of crimes known collectively as "felonies".
