The right to die may be among the most legally complex and culturally sensitive areas of civil rights to emerge in our time. The thorny issues associated with a terminally ill individual's right to self-determination, and the disposition of individuals who are incompetent to make right to die decisions for themselves, promises to keep all parties involved - health care professionals, medical ethicists, families, lawyers, judges, and state legislators -busy for some time to come. To this point, the state courts have taken the lead in the right to die debate, while the state legislatures have tended to drag their collective feet. This article lays the case law groundwork for right to die decision making, then goes on to assay the legislative responses to the issue that have been rendered in the fifty states. 相似文献

The Iran-Contra affair is an example of the type of event that is expected to give rise to a rally of public opinion behind the president. However, the public's response to this event, uncharacteristically, was a sharp decrease in support for President Reagan. This case study constitutes an attempt to explore the sources of the public opinion response to foreign policy events. Statements of political elites, news coverage and commentary, and public opinion assessments are examined to test the patriotism, priming, and opinion leadership explanations of the rally phenomenon. The actions of opinion leaders appears to provide the best explanation of the differential public response to the Iran-Contra affair. 相似文献
