You don't have to be wrinkled or rich to go under the knife. New techniques are luring more and younger patients, while doctors hurry to set up shop. But there are risks as well as options in cosmetic surgery's new age. 相似文献

Congress approved the superconducting supercollider (SSC), but later cut all funding after construction for the project had begun. We claim that this reversal was due, in part, to a problem of time inconsistency. Representatives from states in contention to receive the project had an incentive to support it early in the process. Once Texas was chosen as the SSC site, the other contender states had a greatly diminished incentive to continue to support it. Our empirical results show that the probability of switching from ‘for’ to ‘against’ the project is significantly higher for representatives from the former contender states. 相似文献

Linear and curvilinear associations between experiences in the same- and other-sex peer groups and the protective functions of friendship with an other-sex peer for early adolescents without a same-sex friend were examined in a sample of 231 fifth, sixth, and seventh grade girls and boys. Findings indicate that (a) at the level of the individual, early adolescent girls and, to a much smaller extent, early adolescent boys show a preference for same-sex peers; (b) this unilateral difference in expansiveness accounts for differences in participation rates in same -and other-sex friendships; (c) children of both sexes who are either very popular or very unpopular are more likely than other children to have other-sex friends; and (d) among children without a same-sex friend, having an other-sex friend is linked to higher levels of perceived well-being for boys and lower levels of well-being for girls. Each of these results is discussed according to our understanding of how the same- and other-sex peer systems function as a system to affect development in early adolescence. 相似文献

The purpose of this study was to 1) compare general affective dispositions (depression and anxiety) and negative affect during interpersonal conflict as a function of attachment security, 2) examine appraisals as a function of attachment style and as predictors of coping, 3) compare strategies of coping with interpersonal conflict as a function of attachment style, and 4) investigate the roles of attachment style, affect, and appraisals in predicting coping in the context of interpersonal conflict. Seventy-three late adolescent females participated. Insecure participants reported higher levels of depression, anxiety, and negative affect during interpersonal conflicts. Insecure participants were more likely to cope with interpersonal conflicts through support seeking or avoidance. Hierarchical regression analysis indicated that general and specific attachment style, affect, and appraisals significantly predict coping strategies. Implications for general and specific models of attachment as organizational constructs and attachment as a predictor of coping with interpersonal and non-interpersonal stressors are discussed. 相似文献
