Temporality

Bothe of the following paragraphs are from a same book. Does "temporality" has different meanings in these paragraphs? What do you think it means in each of them?

Paragraph #1:

While the flaunting of femininity in its entire fetishistic garb can be read as acting in a performative manner to deconstruct the naturalisation of feminine tropes, it always risks coming up against the edges of its own excesses and falling prey to the accusation of the very thing it sought to critique. On the other hand, when Stehli positions herself in the poses of the mannequins used in Allen Jones’s tables and chairs, she is creating a scenario which displays a knowing double-take in relation to gendered authorship and the temporality of how art practices come to mean different things at different times. She is posing the question of what it means for the woman to stage her own subjection at this time in history – is it empowering? Are we are at a point in time where we can see through the performance rather than taking it as a sign of flamboyant narcissism with little critical edge?

Paragraph #1:

Sherman’s images. ‘Base Materialism’ is based on Bataille’s scatological notions of ‘the science of filth’ in which all phenomena are brought down to the same level of putrescent value, a shift in emphasis which works to undermine traditional materials and hierarchies. We might think of Mike Kelley’s work here, although Krauss and Bois are careful to avoid dealing with his work in terms of its abject content and instead focus on how it might operate as a process of alteration or desublimation. ‘Pulse’ challenges the Modernist exclusion of temporality from the visual field. Again this links with horizontality, in that pulsation involves an endless beat that punctures the disembodied self-enclosure of pure visuality, and according to Krauss incites an eruption of carnality.
