Is "acculuration" a word?

I am critiquing an article by Katherine Spaht for a class, and I came across the word “acculuration” and “acculurated” in the article. When I went to dictionary.com to find out what they meant since I had never heard of them, I couldn’t find them. I found a word which may be what she was looking for: “acculturation.” Is this what she meant? Basically, is “acculuration” a word?

Small quote from the Judicial Testimony this came from:

Thanks.

Here’s a copy if anyone’s interested:

http://judiciary.senate.gov/testimony.cfm?id=1118&wit_id=3184

It’s about 3 or 4 paragraphs down.

It’s likely a typo:
acculturation

I think it’s pretty clear that “acculturation” is the intended word. Its meaning fits well in the context given.

::Waits for someone to tell him that the OED lists “acculuration” as an accepted variant for “acculturation.”::

Yeah, the OED doesn’t list “acculuration”. So it’s either a typo or a hapax legomenon.

I thought that’s what it was, but it was used twice in the same paragraph so I thought I may have been missing something.

Well, that rules out hapax logomenon.

(I vote for typo.)

dis legomenon then.
