Women\u27s Age of First Exposure to Internet Pornography Predicts Sexual Victimization

Increases in the availability and accessibility of Internet pornography have led growing numbers of children to become consumers of sexually explicit media. Research has identified negative behavioral and attitudinal outcomes associated with Internet pornography use in childhood and adolescence, but few studies have examined sexual victimization as a correlate. The current study aimed to examine the association between age of first Internet pornography exposure and sexual victimization. Data from 154 undergraduate women yielded several important findings. Women who viewed Internet pornography unintentionally at a younger age reported more sexual victimization. Specifically, compared to women who were first unintentionally exposed to Internet pornography at age 14 or older, women with unintentional first Internet pornography exposure before the age of 14 reported more childhood sexual abuse, sexual abuse in adulthood, and more instances of sexual coercion and aggression. Women with younger age of unintentional Internet pornography exposure also reported more interpersonal sexual objectification than women who had never viewed Internet pornography at all. Age of first intentional exposure to Internet pornography was not related to women’s self-reported experiences of objectification, although this may be because women’s intentional exposure tended to happen at older ages. Overall, the results of this study suggest that women’s unintentional Internet pornography exposure at a young age may contribute to a potentially harmful sexual socialization. Early Internet pornography exposure in childhood should be considered a potential risk factor for women’s sexual victimization

Reaction between CH3O2 and BrO Radicals: A New Source of Upper Troposphere Lower Stratosphere Hydroxyl Radicals

Over the last two decades it has emerged that measured hydroxyl radical levels in the upper troposphere are often underestimated by models, leading to the assertion that there are missing sources. Here we report laboratory studies of the kinetics and products of the reaction between CH3O2 and BrO radicals that shows that this could be an important new source of hydroxyl radicals:BrO + CH3O2 --> products (1). The temperature dependent value in Arrhenius form of k(T) is k(1) = (2.42(-0.72)(+1.02)) X 10(-14) exp[(1617 +/- 94)/T] cm(3) molecule(-1) s(-1). In addition, CH2OO and HOBr are believed to he the major products. Global model results suggest that the decomposition of H2COO to form OH could lead to an enhancement in OH of up to 20% in mid-latitudes in the upper troposphere and in the lower stratosphere enhancements OH of 2-9% are inferred from model integrations. In addition, reaction 1 aids conversion of BrO to HOBr and slows polar ozone loss in the lower stratosphere
