Streetwise and savvy

1. Does "what is at stake is the functionality of the self in a world that ..." mean "what is considered is the functionality of personal identity in a world that ..."?

2. Does "still denies agency and control to certain subcultures and social groups" mean "a world that ignores the rights of certain subcultures and social groups"

3. Does "Clear parallels and correspondences of this sort in contemporary art have been identified in the examples discussed above" mean "the examples discussed above are instances of such parallelism and relationship between art and advertising"?

4. Does "but specific appropriations from artworks have not been a noticeable feature. " mean "but advertisements do not noticeably appropriate artworks"?

5. Does "is streetwise and savvy enough" mean "is replete with street identity enough"?

In its involvement in cultural politics and its play with the politics of representation, Nike advertising may be said to have moved well into realms of critical practice that are normally the territory of non-commercial art forms.
As in so many contemporary advertisements, references to the product and its material value are muted in favour of a brand image, which in this case attaches itself to values of another order that are concerned with the politics
and problems of everyday life. As in so much contemporary art, what is at stake is the functionality of the self in a world that, despite notable advances, still denies agency and control to certain subcultures and social groups. What brings these advertisements closer to art is the fact that they are discursive and invite reflectivity and critical engagement from the viewer. Clear parallels and correspondences of this sort in contemporary art have been identified in the examples discussed above, but specific appropriations from artworks have not been a noticeable feature. The reason for this may be that the brand image is streetwise and savvy enough in itself not to need the extra capital that such borrowings would bring or perhaps that Nike advertising has already established itself on the back of another form of cultural capital by featuring celebrity sports figures such as Bo Jackson and Michael Jordan (Art and Advertising by Joan Gibbons).
