Linguisticians are intrigued by "backshift", which is what they call a change of emphasis in a multi-syllable or compound word. It often indicates that a two-word phrase is becoming a one-word noun modifier (e.g., ICEcream cone, BACKseat driver). Hence Mrs Steve's pernicious habit.

But sometimes it indicates that the word you thought was a adjective or a noun is actually a verb in this context (e.g., COMpact, n. an agreement or cabal; COMpact, adj., small; comPACT, v., pack together). English has quite a few of these, and I'm pretty sure they all come from Latin/Old French roots. Think of COMbat and comBAT, where the Anglo-Saxon word "battle" always has the stress on the first syllable although it can be either a noun or a verb.

As for REsearch and FEYEnance, they are but more examples of American v. British usage. Put them on the list with LABratory (labORAtory) and CONtroversy (conTROversy).
