Not sure on #1.  However, #2 I believe is because "mean" is the plural
form, in this case "lack of accounts mean."  Accounts is plural, so mean is
also plural.  If the sentence said "lack of a contemporary account," the
writer would have used "means" instead as account is singular.

At least that is how I was taught it.  :)
