Internet pioneer Yahoo is scheduled to report its fourth-quarter results after the stock market closes Tuesday. And all eyes are on Carol Bartz, the technology veteran who replaced Jerry Yang earlier this month as the firm’s CEO.

Most analysts expect Bartz — known as a tough, savvy leader — to start off by setting a low earnings hurdle for Yahoo to clear in 2009, giving her a better opportunity to surpass expectations as she tries to prove she is the right person for the job.
