When do I use の/こと as a nominalizer, and when do I use というの/ということ?


I'm studying nominalizers and don't understand when to use の/こと and when to
use というの/ということ.

For example, in the sentence:

> こんなによく[遅刻]{ちこく}をする **というのは** [問題]{もんだい}ですよ。

Could I say:

> こんなによく[遅刻]{ちこく}をする **のは** [問題]{もんだい}ですよ。

Is there any rule to choose の/こと or というの/ということ?




As far as I know, they are generally identical in meaning and function.
However, adding という seems to add emphasis to the meaning of the preceding
phrase. I do not believe there is any general rule separating the usage of the
two. (As long as you're using の and こと properly, of course.)

It's hard to use Google to find sources to back this up (besides Yahoo
Answers, which isn't much of a source).
