...interviews from age 10 to age 17, then tracked their arrest records in adulthood. Researchers also interviewed the teenagers' parents, schoolmates and teachers. The study accounted for variables such as family income, single-parent-home status and earlier behavior problems (such as hyperactivity) that are known to affect delinquency risk.

Past research has also shown that peer exposure can worsen behavior. In a 1995 study conducted by Dishion involving 158 high-risk families in Oregon, researchers compared the impact on teens' behavior of four interventions: parenting groups focused on effective discipline, social-skills-training groups for teens, both the parent- and teen-focused group interventions, or no group treatment at all. Overall, the parent-focused group was most effective, leading to reductions in teen smoking and misbehavior at school. The teen-focused group, by contrast, significantly increased participants' rate of aggressive behavior and smoking; in the combination group, kids showed...
...family therapy or one-on-one counseling - or any intervention that doesn't aggregate troubled teens - is safer and more likely to be effective than group activities. But if groups must be used, experts say that high supervision and low child-to-staff ratios are essential to minimize the risk of behavior contagion...
Since extinction tends to target groups of vulnerable species, conservationists would be smart to identify and focus their efforts on the most susceptible families. That means species that have a narrow geographic spread - always a risk factor for extinction, in case something happens to their habitat - and, interestingly, large body size, which also tends to be associated with extinction. "It's a quick and dirty way to get a better picture of which species are likely to be most impacted," says Roy. "Then you can go in and mark your priorities." Extinction may be a part of life...
Balancing the social costs of widespread school closures - including the risk of unsupervised children at home - against the potential health risks of remaining open, government officials advised schools to not shut down in most cases. "If there are a handful of [flu] cases in a school, the real goal is to keep the school open," Secretary of Education Arne Duncan told reporters at a press conference also attended by Secretary of Health and Human Services Kathleen Sebelius, Secretary of Homeland Security Janet Napolitano and CDC director Dr. Thomas Frieden...
