Is the doctrine of "Particular Election" synonymous with that of "Unconditional Election"?

I learned today, from *The Oxford Dictionary of Quotations*, that the phrase **"Damned if you do and damned if you don't"** was coined by Lorenzo Dow , the 19th century American preacher. According to said publication, Dow was speaking specifically about the Calvinist doctrine of **"Particular Election"**. I've not heard of Particular Election before, but I am familiar with **Unconditional Election**, and, judging by the phrase, that sounds rather like what Dow was getting at. **Are Particular Election and Unconditional Election synonymous?** If not, please give me a condensed version of what Particular Election entails.
