Specifically, what can and should it contribute to the unions' own efforts at revival?

After a long moment of terror on Bolis's face, the Doctor stopped his attempts at revival.

An attempt at revival of The Spot in 2004-2005 under the owners who did acquire the site's intellectual property seven years earlier also failed.

There had to be some sort of assurance that everyone who died would be guaranteed his chance at revival.

After every other attempt at revival fails, an adrenaline injection to the heart brings him back.

Until recently, all of the various attempts at revival were blocked by Austrian authorities.

There were periodic attempts at revival but none achieved much success.

All the miscarried efforts at revival over the past years have lacked one essential ingredient.

In my observation, none of the countless, bootless efforts at revival has involved from the start such a person or team.

Nonuya is nearly extinct, but attempts are being made at revival.
