This study emphasizes the need to include purchasing, or procurement, as a topic in the graduate-level public administration curriculum. It notes the absence of purchasing research in mainstream public administration journals and in leading public financial management textbooks. The study also reports the results of a survey mailed to the purchasing directors of the 46 largest U.S. counties outside Florida. The survey was designed to familiarize academians and practitioners with various administrative, legal, structural, and procedural dimensions of county procurement policies. Areas of greatest deficiency are those dealing with protest and appeals procedures and contract monitoring, and to a lesser extent procedures for declaring an emergency, entering into intergovernmental purchasing agreements, and contracting with minority businesses. The most comprehensively-covered elements are those delineating award authority, small purchase authority, methods of soliciting bids, definitions of emergencies and professional services, and procedures for contracting professional services. 相似文献

Loperamide is an over‐the‐counter, μ‐opioid receptor agonist commonly used as an antidiarrheal agent. Loperamide was thought to have minimal abuse potential due to its low bioavailability and limited central nervous system activity; however, there have been increasing reports of loperamide misuse in supratherapeutic doses to achieve euphoria and/or avoid opioid withdrawal. A literature review suggests a rise in loperamide abuse was inevitable, with substantial increases in reported cases over the last decade. Five fatal cases of toxic medication use where loperamide was listed as a primary or contributory cause of death were identified at the Medical University of South Carolina. The characteristic autopsy demographics and findings are described, and the mechanisms of abuse and toxicity of loperamide are reviewed. Loperamide overdoses are a growing concern from both a forensic and clinical standpoint, and the frequency of reported cases will likely increase as awareness grows within the medical and toxicological communities. 相似文献

During the 1970s, Cleveland's capital improvement plan (CIP) was scorned as a bad joke, and the city's roads, bridges, and public buildings fell into disrepair. The city's default on its fiscal obligation in 1978 seemed to cap the city's infrastructure problem; there was no comprehensive strategy for capital spending and in a bankrupt city, no money to spend in any event. Yet, during the 1980s, with support from the administration, the business community, and the innovations of a small group of dedicated urban planners, the CIP was restructured and hundreds of millions were systematically invested in public infrastructure. By the 1990s, most of the innovative changes of the 1980s seemed to be institutionalized, but there were ominous clouds on the horizon. 相似文献

Negotiation and nonviolent action are arguably the two best methods humanity has developed for engaging constructively with conflict. Both have played central roles in helping manage or resolve seemingly intractable conflicts, sometimes sequentially and sometimes in tandem. But experts and practitioners in both fields often underestimate the relevance and effectiveness of the other. This article explores the interface between the fields of negotiation and nonviolent action, their mutual commitment to engage constructively with conflict, and the concern both methods share for leverage, power, and strategic preparation and action. After examining the shared linkages, this article highlights how the two fields have synergistic qualities when utilized together in the same conflict. Using examples from a diverse set of conflicts, the overlap explored in this article lays an important foundation for the future convergence of the two fields. 相似文献
