The public choice literature contains little formal analysis of the bureaucratic choice of production modes — public or private — of publicly funded services. An important question to be addressed is why some governmental bodies choose to provide a publicly funded service with publicly owned and operated production units whereas other governmental bodies contract with private firms to provide the same publicly funded service. This paper is the first formal attempt to remedy this gap in the literature. We develop a theoretical explanation of the government decision maker's choice between public and private production modes based on utility maximizing behavior. We then examine empirically this choice employing logit analysis. The empirical results, which include several tests for robustness, confirm our theoretical explanation. The results are significant and suggest that non-monetary constraints are an important factor affecting this choice of production modes and that monetary constraints are less influential. 相似文献

We reviewed a series of 66 deaths in Washington State between 1995-2000 in which tramadol (Ultram and Ultracet, Ortho-McNeil) was detected in the decedent's blood, in order to assess the role tramadol was determined to have played. Additionally, we reviewed a series of 83 impaired driving cases in which tramadol was detected in order to establish a non-lethal blood tramadol concentration reference range. In both populations, tramadol was consistently found together with other analgesic, muscle relaxant, and CNS depressant drugs. Death was rarely attributable to tramadol alone. However, tramadol may be a significant contributor to lethal intoxication when taken in excess with other drugs, via the potential interaction with serotonergic antidepressant medications, as well as the potential for increased CNS depression. Although the incidence of tramadol detection has increased consistently over the last eight years, there is no evidence of a corresponding increase in the number of cases in which death was attributed solely to tramadol. Blood drug concentrations in many deaths exceeded the therapeutic serum range of 0.28-0.61 mg/L; however, the concentrations overlapped almost completely with the range identified in living subjects arrested for impaired driving. These findings suggest caution in the interpretation of blood tramadol concentrations outside of the recognized therapeutic range. It also suggests that the drug, even when used in moderate excess, is not a principle cause of death in suicidal or accidental deaths. 相似文献

Abstract Community development researchers, practitioners, and funders have recently begun to emphasize the need for community development corporations (CDCs) to build capacity. However, the practice of using the term capacity without carefully defining it allows for a wide range of meanings to be assigned to the term and hinders efforts to study and measure it. Capacity is often defined narrowly in terms of housing production, oversimplifying a complex concept and process. To remedy this shortcoming, we create a framework that views capacity more broadly by dividing it into five components: resource, organizational, programmatic, network, and political. We believe that this more concrete way of thinking about capacity will be particularly useful to practitioners, funders, and policy makers. We apply our definitions to CDCs, particularly those that work with local intermediaries called community development partnerships (CDPs), in order to better understand the role of CDPs in the process of building capacity. 相似文献
