Violent lyrics in songs increase aggression-related thoughts and emotions and could indirectly create a more hostile social environment, a study released on Sunday by a U. S. psychology association found. The Washington D.C. -based American Psychological Association (APA) released the study, resulting from five experiments involving over 500 college students, in the May issue of the Journal of Personality and Social Psychology.
The violent songs increased feelings of hostility without provocation or threat, according to the study. It said the effect was not the result of differences in musical style, specific performing artist or arousal properties of the songs. Even the humorous violent songs increased aggressive thoughts, the study said.
The group said the study contradicts a popular notion that listening to angry, violent music actually serves as a positive catharsis for people.
The music industry came under criticism from lawmakers in October for failing to use more descriptive parental advisory labels that specify whether the music contains sex, violence or strong language.
But the Recording Industry Association of America (RIAA) has said that current CD labels give parents enough information without violating the right to free expression. The RIAA is the trade group for the world’s five big labels, including AOL Time Warner Inc. , EMI Group Pie. , Bertelsmann AG, Vivendi Universal’s Universal Music and Sony Corp..
Results of the APA’s experiments showed that violent songs led to more aggressive interpretations of ambiguously aggressive words and increased the relative speed with which people read aggressive versus non-aggressive words. "Such aggression-biased interpretations can, in turn, instigate a more aggressive response, verbal or physical, than would have been emitted in a nonbiased state, thus provoking an aggressive escalatory spiral of antisocial exchanges," said researcher Craig Anderson, in a statement.
While researchers said repeated exposure to violent lyrics could indirectly create a more hostile social environment, they said it was possible the effects of violent songs may last only a fairly short time.

It can be concluded from the passage that ()

A:some musical styles would lead to a short period of increased social hostility B:researchers were divided about the fundamental causes of aggressive emotions C:parents needn't worry a lot about their kids' occasional exposure to violent songs D:music industry would have to be more alert to violent words in its music

CT Scans and Lung Cancer

? ? ?Small or slow-growing nodules (小结节) discovered on a lung scan are unlikely to develop into tumors over the next two years, researchers reported on Wednesday.
? ? ?The findings, reported in the New England Journal of Medicine, could help doctors decide when to do more aggressive testing for lung cancer. They could also help patients avoid unnecessarily aggressive and potentially harmful testing when lesions (损伤) are found.
? ? ?Lung cancer, the biggest cancer killer in the United States and globally, is often not diagnosed until it has spread. It kills 159,000 people a year in the United States alone.
? ? ?The work is part of a larger effort to develop guidelines to help doctors decide what to do when such growths, often discovered by accident, appear in a scan.
? ? ?High-tech (高技术的) X-rays called CT scans can detect tumors -- but they see all sorts of other blobs (糊涂的一团) that are not tumors, and often the only way to tell the difference is to take a biopsy (活检), a dangerous procedure.
? ? ?At the moment, routine lung cancer screening is considered impractical because of its high cost and because too many healthy people are called back for further testing.
? ? ?Good guidelines could help make lung cancer screening practical, Dr. Rob van Klaveren of the Erasmus Medical Center in Rotterdam, the Netherlands, who led the new study, said in a telephone inter view.
? ? The team looked at 7,557 people at high risk for lung cancer because they were current and former smokers. All received multidetector (多层螺旋) CT scans that measured the size of any suspicious-looking nodules.
? ? Volunteers who had nodules over 9.7 mm in width, or had growths of 4.6 mm that grew fast enough to more than double in volume every 400 days, were sent for further testing. Of the 196 people who fell into that category, 70 were found to have lung cancer; 10 additional cases were found years later.
? ? But of the 7,361 who tested negative during screening, only 20 lung cancer cases later developed.
? ? In a second round of screening, done one year after the first’, 1.8 percent were sent to the doctor because they had a nodule that was large or fast-growing. More than half turned out to have lung cancer.
? ? The result means that if the screening test says you don’t have lung cancer, you probably don’t, the researchers said. "The chances of finding lung cancer one and two years after a negative first-round test were 1 in 1,000 and 3 in 1,000 respectively," they concluded.
The new study indicates that in case of small or slow-growing lung nodules

A:you cannot be too careful. B:cancer is just a matter of time. C:a biopsy is unnecessary. D:more aggressive testing is a must.
