WASHINGTON (Reuters): A Columbia University review of a now-discredited Rolling Stone story about an alleged gang rape at a University of Virginia fraternity is due out on late Sunday, addressing the questions of journalistic ethics raised by the provocative article. Rolling Stone commissioned the review after backtracking on the story, “A Rape on Campus,” which caused an uproar over the issue of campus sexual assault when it was published in November. But discrepancies in the story soon surfaced, and the magazine was forced to retract it.
 The story’s autopsy could lead to a shakeup at Rolling Stone, founded in 1967 by editor Jann Wenner. The magazine, best known for its pop music coverage, was a pioneer in the “New Journalism” of the 1960s and ‘70s, an approach characterized by a reporter’s immersion in the subject matter.
