Emerging adulthood is a period in which profound role changes take place across a number of life domains including finance, romance, and residence. On the basis of dynamic systems theory, change in one domain should be related to change in another domain, because the concept of development according to this approach is a relational one. To evaluate this hypothesis dynamic systems analysis was applied to data from narrative interviews of 200 respondents covering the years between 17 and 27 to examine how change in one domain affects change in another domain. In each dyad, the fit of the model significantly deteriorated when the coupling between domains was removed providing support for the assumption of interdependency. On average, assuming greater responsibility in one domain was associated with assuming greater responsibility in the other domain. However, imbalances were also observed in which role assumption in one domain far exceeded role assumption in another domain. These imbalances can have detrimental effects and indicate the utility of a balanced approach to development. The findings underscore the importance of studying the relational unit between domains, which is critical to understanding development over time within domains.

This paper asks whether the criminal law can have any legitimate concern with obscene language. At most, such a concern could be justified by the need to protect auditors from offense, since it is not plausible to think of exposure to dirty words as harmful or inherently immoral. A distinction is drawn between “bare utterance and instant offense,” on the one hand, and offensive nuisance and harassment, on the other. Only when obscene language is used to harass can it properly be made criminal. Finally, I criticize in some detail judicial reasoning in the case of F.C.C. v. Pacifica Foundation, and conclude that obscene language on the public media is not properly subject to governmental regulation, whether- by criminal law or otherwise. *** DIRECT SUPPORT *** A9102008 00002  相似文献
