The examination of illicit cocaine

A laboratory system of examination of illicit cocaine exhibits is described. Separation and identification of many of the components in exhibits are achieved by the use of capillary column gas chromatography and a Finnigan ion trap detector. Further examination and quantitation of the components of exhibits is achieved using two high performance liquid chromatographic (HPLC) systems. Both of these systems use identical reverse phase C8 columns. System 1 employs a solvent composed of 40% acetonitrile, 10% tetrahydrofuran and 50% 0.1% v/v aqueous triethylamine. The eluant is monitored at 280 nm. This system is preferred for routine quantitative analysis of cocaine and related alkaloids in exhibits. System 2 employs a solvent composed of 30% acetonitrile and 70% 0.05M phosphate buffer (pH = 5.0). The eluant from this system is monitored at both 220 and 280 nm. This system offers advantages in sensitivity. The relative retention times of a number of relevant substances as determined with gas chromatography and the two HPLC systems are given. The utility of the methodology for the identification and comparison of exhibits is demonstrated.     

Medicare reform: social and ethical perspectives

Despite Medicare's success as a social program, its future is in question because of the program's enormous costs. Because the issue of Medicare reform has been forced upon us at this juncture by a crisis of finance rather than by the long-standing inequities in the present system of paying for the health care of the elderly, questions about how best to secure its fiscal integrity have seized the attention of the public. Yet, such questions are hard to contain; they force an examination of broader and more fundamental issues. In this article, we examine the validity of the ultimate moral and social rationales for continuing Medicare in something approximating its present form; the legitimacy of a social entitlement program that is age- rather than means-based; the implications for the future of health care reform if significant changes were to be made in the Medicare program and its underlying rationale; and the possibility that changes in that program may jeopardize the chances for a more rational, just, and systematic approach to the provision of health care to all Americans.     

Citizen Involvement Efforts and Bureaucratic Responsiveness: Participatory Values, Stakeholder Pressures, and Administrative Practicality

This article addresses the efforts of local governments to involve citizens in administrative processes. In particular, we explore the following questions: What social and political groups in the community promote citizen involvement? Which groups awre likely to succeed? What barriers obstruct citizen involvement efforts? Do administrative attitudes make a difference in undertaking citizen involvement? Using survey data, this study tests a framework that assumes the decision to involve citizens in administrative processes reflects administrative responsiveness to salient community stakeholders, normative values associated with citizen involvement, and administrative practicality. The statistical results confirm the bureaucratic responsiveness framework and point to future directions for citizen involvement research and practice.
