...normal and functioning to disordered and tragic. To the annoyance of some old-fashioned DSM defenders, he made the case that the DSM should regard mental illness as "continuous with normal": less like leukemia and more like hypertension. You don't get diagnosed with hypertension until you meet a cutoff point for high blood pressure that takes into account other extenuating factors: your age, for instance, or the conditions under which the blood-pressure reading is taken. Depression should be the same: if you are sad because you just got divorced, the DSM shouldn't necessarily consider you to have...
...Portnuff has documented that listening to earbuds, or in-ear headphones, for 90 minutes a day at 80% volume is probably safe for long-term hearing - a useful cutoff point to keep in mind. (But softer is better: you can safely tune in at 70% volume for about 4½ hours a day.) The risk of permanent hearing loss, Portnuff says, can increase with just five minutes of exposure a day to music at full volume. Over time, the noise can damage the delicate hair cells in the inner ear that transform sound waves to the electrical signals that...
...When a professor in England, Ed Galea, analyzed the seating charts of more than 100 plane crashes and interviewed 1,900 survivors and 155 cabin-crew members, he discovered that survivors usually move an average of five rows before they can get off a burning aircraft. That's the cutoff. In his view - and he's done a lot of statistical analysis - the people who are most likely to survive a plane crash are people who are sitting right next to the exit row or one row away. Not a particular exit row but any exit row. That...
...that Minnesota already had an election law in place to handle close elections, which mandated a hand recount in contests with a margin of victory smaller than 0.5 percent. Coleman’s razor-thin 0.0075 percent margin of victory over Franken in November failed to meet the cutoff, automatically triggering the recount. Unlike the Florida presidential election in 2000, during which Gore had to fight in court to get a recount, in this case there was no question of whether a recount was in order...
...study of 13,258 pregnant women who had had a prior cesarean section, 36% elected to schedule their next c-section delivery before 39 weeks of gestation, the safety cutoff recommended by the American College of Obstetrics and Gynecology (ACOG). ACOG's guideline is based on studies showing that prior to 39 weeks, babies' lungs are often too undeveloped to function properly outside the womb, and babies at this age tend to have difficulty regulating their blood sugar. In the trial, led by Dr. Alan Tita at UAB and published in this week's New England Journal of Medicine, babies...
