In adopting the Health Insurance Portability and Accountability Act of 1996 (HIPAA), Congress made a series of small but significant steps toward improving access to health care benefits. The Act's centerpiece is its new requirements for group health plans and for the health insurance industry for assuring portability, access, and renewability of health insurance coverage. Of nearly equal importance is the pilot program established for testing the viability of medical savings accounts. Other health-related changes include adjustments in the rules governing duplication and coordinating of Medicare-related plans, recommendations with respect to privacy of health information of employees, an increase in the deduction for health insurance costs for self-employed individuals, and permission for unemployed persons to make withdrawals from IRAs and other qualified plans for certain medical services' costs. This article summarizes these and other key provisions of HIPAA.  相似文献

Theodor Herzl published his programmatic book The Jewish State in February 1896. Central to it was the discrimination (and hatred) commonly known as anti-Semitism. Herzl viewed anti-Semitism as the heart of the Jewish Question but also as the potential motivator for Jews to achieve a Jewish state. Herzl's analysis of anti-Semitic discrimination is in many aspects similar to present sociological theories of middle-class minorities. His discussion of the economic aspects is compared with Gary Becker's theory of discrimination, and similarities as well as differences are pointed out.  相似文献

Ninety Breathalyzer instruments (Model 1000) and twenty instruments (Models 900, 900A) were studied using a protocol described by the Department of Transportation's "Standard for Devices to Measure Breath Alcohol." Although the mean of each of three concentrations tested (0.05, 0.10, and 0.15 g/210 L) compared favorably in both series, the standard deviation was consistently higher for the Model 1000 instruments. The Model 1000 instruments also produced a significant number of test results which exceeded the normally expected scientific deviation.  相似文献

The abuse of heroin (diacetylmorphine) in Singapore escalated sharply in 1975 and 1976, as indicated by the 35-fold increase in the number of heroin seizures and the 20-fold increase in the urine samples containing morphine since 1974. A rapid and simple GC method has been described to estimate diacetylmorphine (and caffeine). Monoacetylmorphine and acetylcodeine may be ascertained by an additional step involving acetylation. All gas chromatograms of a large number of samples analyzed consistently had the same pattern, indicating that they possibly had a common origin. This GC "fingerprint," together with the quantitative data, appears to be characteristic of the illicit Asian or Chinese type of heroin found in Singapore. The proportions of the four major ingredients in some twelve typical samples have been tabulated. Statistical data confirming the accuracy and reproducibility of the analytical method have also been presented.  相似文献

Institutional litigation, in which courts are requested to oversee the operation of large public institutions, has been frequently attacked as a departure from the traditional model of litigation. In this Article, Professors Eisenberg and Yeazell argue that the procedures and remedies employed in institutional litigation are not unprecedented but have analogues in older judicial traditions. Nor, they assert, do the doctrines of separation of powers and federalism present any obstacles to institutional litigation. They conclude that the novelty lies in the newly created substantive rights which courts are asked to enforce.  相似文献
