Alcoholism and drug addiction affects the entire family. At least 22 million Americans have been raised in an alcoholic environment. Parental alcoholism and/or addiction can have profound emotional and psychological scars on the children. These homes are often characterized by emotional and or physical insecurity, loneliness, terror and inconsistency. The children from these homes often are extremely insecure have low self-esteem, and have a variety of emotional problems. Adolescents from addictive homes are over-represented in juvenile court as status offenders, delinquents and abuse and neglect cases. This article will discuss this issue and implications for the juvenile justice system and personnel working with these youth 相似文献

The legacy of severe environmental degradation inherited by the new Central and Eastern European (CEE) economies requires liability reform to aid the cleanup of existing pollution sources and create incentives for future environmental risk reduction. The paper analyzes a host of liability approaches to meet these goals, given economic and institutional characteristics specific to the CEE nations, and explores the impact of environmental liability rules on privatization and foreign investment. A principal conclusion of the analysis is that, for a host of efficiency-based reasons, liability should not be retroactively applied to the new owners of privatized firms. Also, the paper advocates the use of national liability funds to finance the cost of existing liabilities, while highlighting dangers associated with their use. In addition to the desirability of alternative privatization mechanisms, the paper also analyzes altemative liability rules to govern prospective environmental hazards. 相似文献

This study examines the unfair trade decisions of the InternationalTrade Commission (ITC) and how they have been affected by Congress.It begins by identifying the means Congress can use to influenceITC decisions and then estimates both the extent to which thesemeans have been used and the extent to which they have shaped theITC's behavior. The study reaches two conclusions. First, Congresshas tried to shape the ITC's behavior, but it has not tried tomicromanage this behavior. Second, while the ITC's behavior hasbeen influenced by Congress, congressional influence is not asimportant as other factors, such as statutory criteria. 相似文献

Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses. 相似文献
