Results of the first national survey of its kind show problem gambling -- described as gambling with three or more negative consequences (for example, gambling more than you intended or stealing money to gamble) in the past year -- occurring at a rate of 2.1 percent among youth 14 to 21.

In countries where malnutrition is prevalent, better-educated women weigh more. But in wealthier countries -- with rapidly growing rates of obesity -- better-educated women weigh less. The United States was the only nation surveyed in which better-educated men were skinnier than less-educated men. In every other country, the average male body mass increased with every additional year of schooling.

Traditional machismo is the stereotypical masculine personification of a Mexican-American man as controlling, sexist and violent, correlated with antisocial behavior, aggressive masculinity and wishful thinking as a coping style. These men tend to have more difficulty expressing emotion. However, traditional machismo did not correlate with dominance as hypothesized. Caballerismo is a positive image of a man as the family provider who respects and cares for his family. It depicts Mexican-American men as chivalrous, nurturing and noble. These men rated higher on the social connectedness scale, saying they felt value in their family relationships and were in touch with their feelings, and the feelings of others. They also displayed more practical ways of solving their problems.

"When she says 'It's getting late,' he may hear 'So let's skip the preliminaries,'" the researcher says. "The problem is that he is interpreting what she said by trying to imagine what he would mean -- and the only reason he can imagine saying 'It's getting late' while making out is to mean 'Let's speed things up.'"

In a study of college students, researchers discovered a link between what psychologists call relational victimization in adolescence and depression and anxiety in early adulthood. Rather than threatening a child with physical violence, these bullies target a child's social status and relationships by shunning them, excluding them from social activities or spreading rumors.

A smaller gender difference exists in Europe, Australia and New Zealand, but in the rest of the world short boys and girls are treated at the same rate.
