A hallmark of chronic infection with the oral pathogen Porphyromonas gingivalis is the induction of a chronic inflammatory response. P.

CEOs rewarded for wrong kind of growth, Rotman paper finds

Toronto – Growth is good, right?

Not always.

But compensation committees still tend to reward CEOs when their companies grow due to investments – even though that has been found to hurt long-term shareholder value – rather than only rewarding growth due to improved profitability, says a paper co-authored by a professor at the University of Toronto's Rotman School of Management.

Angry at God? If so, you're historically in good company

The notion of being angry with God goes back to ancient days. Such personal struggles are not new, but Case Western Reserve University psychologist Julie Exline began looking at "anger at God" in a new way.

"Many people experience anger toward God," Exline explains. "Even people who deeply love and respect God can become angry. Just as people become upset or angry with others, including loved ones, they can also become angry with God."
