Moving stress

[Solitario]

Please I need help with this:

You use moving stress with some nationalities (ending in ese) and also with numbers (_teen, twenty-two)

Examples:
He's a Portugese writer.
We have fourteen children.

Am I right?

What about these examples? Do they have moving stress?
They are European capital cities.
It's an afternoon party.
It's a seventeenth century house.

Yes, there is also stress shift in your examples:

They are European capital cities.
It's an afternoon party.
It's a seventeenth century house.

The primary stress falls on the first syllable of these words because they are used attributively. This change occurs in double stressed words (i.e. they have a primary and a secondary stress)
