One more bit of advice to students this afternoon: If you wish to write forceful sentences, do not be a writer, who places a comma between the subject, and verb of a sentence, nor between parts of a compound verb or noun with, only two items, nor in the middle of, a prepositional phrase. (Remove the underlined commas and reread.)
Doctoral students and Ph.D.s tend to be addicted to the dual comma interruptus, but other students appear to have a habit with the single, self-pleasuring comma.
