Before, I share my answer to the questions that I posed, here are definitions I'm using for 'appropriateness', 'efficacy', and 'self-promotion':

http://www.answers.com/topic/appropriate gives this definition for 'appropriateness'
"Suitable for a particular person, condition, occasion, or place; fitting".

And http://www.answers.com/topic/efficacygives this definition of & autonyms for 'efficacy':
"efficiency; productiveness; Antonyms: failure, inefficacy, inefficiency, unproductiveness, uselessness, weakness".

That same website gives the definition of 'self-promotion' as "Promotion, including advertising and publicity, of oneself effected by oneself" http://www.answers.com/topic/self-promotion
