I work in both the executive and IC sides, and no, the "ATTENTION AND EFFORT" clause is not standard, at least, not that I've seen. Typically at most you'll see no-moonlighting clauses but I've never seen them phrased quite so repugnantly as they have been here - after reading the blog post about Japanese salarymen in particular it makes me throw up in my mouth a little. I'll never sign anything that says "Employee will devote Employee’s entire productive time, ability, attention, and effort to furthering <company's> best interests". That's bullshit, and no, not common.
