While numerous sources have focused on employee rights and employer obligations under the Americans with Disabilities Act, this article will emphasize employer rights with respect to mental disabilities under the ADA. Specifically, it addresses the ADA's definition of "mental disability," the right of employers to screen job applicants in spite of the ADA, the conditions under which an employer may require an employee to undergo a "fitness for duty" examination, and the limits of the duty to "reasonably accommodate" an employee with a mental disability.  相似文献

Challenges the use by policy researchers of a model for comparing adolescent and adult decision making that is based on informed consent standards. An expanded decision-making framework designed to evaluate judgment in adults and adolescents can better test the empirical basis of paternalistic legal policies. The theoretical and empirical literature on the informed consent framework is critiqued and an alternative framework incorporating judgment factors is proposed. Three judgment factors—temporal perspective, attitude toward risk, and peer and parental influence—and their effects on decision making are explored. Finally, implications for future research are analyzed in several decision-making contexts.Several of the ideas in this article were originally presented by the first author and were published as part of a symposium on competence (see Scott, 1992). The current article expands and refines these ideas, provides a more substantial research base, and suggests several future research directions. We thank Joseph Allen, Richard Bonnie, Baruch Fischhoff, William Gardner, John Monahan, Edward Mulvey, Richard Redding, Paul Slovic, and three anonymous reviewers for their helpful comments. Special thanks to Thomas Grisso for providing much constructive criticism and to Wendy Shang for outstanding research assistance. Finally, we would like to acknowledge the MacArthur Foundation, which supported this work in its early stages.  相似文献

This article reports the development and psychometric properties of three standardized and objectively scored measures, the MacArthur Treatment Competence Research Instruments. They were designed to assess abilities related conceptually to four legal standards for competence to consent to treatment: understanding, appreciation, rational manipulation (reasoning), and expressing a choice. Scoring reliability, internal consistency, intertest correlations, and test-retest correlations were examined with data from samples of hospitalized patients with schizophrenia, major depression, and ischemic heart disease, as well as matched non-ill community samples. The results indicate very good interscorer reliability and provide guidance for the use of the instruments and interpretation of their results in future research on patients' decisional abilities in treatment contexts.  相似文献

Given the complexity of federal Medicaid law and the limitations it imposes on state flexibility, it is likely that states will continue to ask the Secretary to grant waivers under Section 1115 to allow them to pursue new approaches to health care reform. The results of currently operational Section 1115 projects involving statewide managed care systems will be useful in evaluating the Medicaid reform measures currently under discussion in other states and at the federal level. In particular, the ability of the states to control Medicaid and indigent care costs and to utilize federal dollars more efficiently should prove important in evaluating a block grant approach to federal Medicaid funding. Moreover, Section 1115 project results that bear on the sufficiency of various Medicaid capitation rate methodologies will also be of value as more states expand the use of managed care arrangements for their Medicaid populations.  相似文献

Hospitals tempted to operate their own physician incentive plans are reminded that, under OBRA 1986, they are precluded from paying physician incentives of any kind to reduce or limit Medicare or Medicaid covered services. In light of the proposed regulations and the guidance of the preamble, hospitals should review their incentive plans to determine whether physicians providing direct patient care are receiving prohibited payments. Further, supervising physicians who are receiving incentives for certain hospital departments may not influence direct care over patients served by those departments, even through other physicians. Some risk may also exist if incentives are based on a formula that considers patients of the supervising physician's medical group. Finally, it may be useful to develop a utilization and quality of care review program specifically designed to assure that patient undertreatment does not occur as a result of any supervising physician incentive program.  相似文献

In the West economically motivated crime is usually perceived as a matter for the police while the performance of the economy is a matter for the political authorities. This paper argues that the growth and evolution of the modern underground economy has made such a distinction obsolete. Not only have the frontiers between the legitimate and the criminal sectors of the economy blurred, but the distinction between the explicitly criminal and the merely informal aspects of the modern underground economy has become largely meaningless. Given the tremendous growth of underground activity, this means that the issue must now be addressed not just on the enterprise level, as a police matter, but on the level of the economy as a whole, by economic policy makers. This in fact is something that many developing countries long ago realized. The paper therefore asks whether developing countries have been any more successful in using monetary, fiscal and balance of payments policy to mitigate the adverse social and economic impact of widespread underground economic activity than have Western countries who have relied mainly on the sanction of criminal law. It concludes that both approaches are deficient in so far as they neglect the degree to which modern underground activity can no longer be seen as a manifestation of deviant economic behavior so much as a virtual economic insurgency against the status quo distribution of income and wealth and the codes of economic behavior which accompany it. However dramatic are the financial manifestations of the spread of enterprise crime, ultimately the challenge it poses must be addressed as the political and ideological level.  相似文献
