Behavior problems were investigated in 342 6- to 18-year-old children adopted from psychosocially depriving Russian institutions
that provided adequate physical resources but not consistent, responsive caregiving. Results indicated that attention and
externalizing problems were the most prevalent types of behavior problems in the sample as a whole. Behavior problem rates
increased with age at adoption, such that children adopted at 18 months or older had higher rates than never-institutionalized
children but younger-adopted children did not. There was a stronger association between age at adoption and behavior problems
during adolescence than at younger ages at assessment. Children adopted from psychosocially depriving institutions had lower
behavior problem rates than children adopted from severely depriving Romanian institutions in the 1990s. The implications
of these results are that early psychosocial deprivation is associated with behavior problems, children exposed to prolonged
early deprivation may be especially vulnerable to the developmental stresses of adolescence, and severe institutional deprivation
is associated with a higher percentage of behavior problems after a shorter duration of exposure. 相似文献

胚胎干细胞在治疗学研究中的应用 总被引:1,自引:0,他引:1

目前有许多研究人员希望能够从事胚胎干细胞的研究。这项研究可能对可移植组织用于对目前认为难以治疗或不能治疗的许多疾病的治疗的发展带来极大的帮助。然而,由于干细胞是源自人体胚胎。这就提出了如下问题:为了治疗学研究,在胚胎植入子宫之前从人类胚胎上获取细胞以从事实验室培养和研究在伦理上能够被接受吗?不同国家的伦理委员会或国家立法机构关于胚胎研究的观点及其采取的解决办法可能存在显著差异。这种差异在多元性世界里是不可避免的。 相似文献

The consumer decision-making model is applied to store clerks faced with determining which customers should be carded for the purchase of alcohol. Manipulated decisional time pressure induced either a vigilant (high involvement) or hypervigilant (low involvement) decision state. Clerks (N = 256) rated four combined shopper–product profiles under conditions of high or low time pressure and assessed the likelihood that the shopper would be carded. Results indicated that increased time pressure reduced the likelihood of being required to present identification and that males were least likely to be asked for identification under high time pressure. The managerial implications and utility of the consumer decision model for enhancing compliance with minimum legal drinking age laws are considered. 相似文献
