A new solid-phase extraction procedure for the determination of cocaine and benzoylecgonine in amniotic fluid, using high flow co-polymeric sorbents is reported. The recoveries of cocaine and benzoylecgonine within the range 0.1-1 mg/l were 95.7% and 50.3%, respectively. The use of high-flow sorbents allowed the easy extraction of amniotic fluid regardless of sample viscosity or physical nature. The use of these solid-phase columns provided many advantages over the more commonly used solvent extraction, including an increase in extraction speed and efficiency, reduced operator time, reduced solvent use and disposal volumes and exceptional extract quality. Further, the determination of amniotic fluid obtained from pregnant cocaine users may provide important information about handling of cocaine by the fetus at various gestational ages. The procedure was successfully applied to amniotic fluid from suspected cocaine abusers.  相似文献

System of cities dynamics in newly industrializing nations   总被引:1,自引:0,他引:1  
Rapid industrialization in such countries as Korea, Malaysia, and Taiwan suggests that the complex functional structures of cities in the periphery may appear early in development. This paper proposes a 4-stage framework for the dynamics of a system of cities in a developing country undergoing industrialization and encompassing both nonindustrial and industrial development. The synthesis is assessed with evidence from the newly industrializing Asian nations of Korea, Malaysia, and Taiwan. The 4 stages of cities' industrial change include 1) increasing primacy with industrial satellites, 2) increasing primacy with industrial satellites and nodal towns on a transport network, 3) rapidly increasing primacy with rapidly growing industrial satellites and nodal towns on the transport network, and 4) decreasing primacy with slowly growing industrial satellites and rapidly growing peripheral industrial towns. The 4-stage synthesis suggests that economic development in the periphery may occur even while the primate city maintains its hegemony over control and coordination functions. Peripheral industrial growth does not challenge this hegemony. The growth of industrial cities is, instead, part of a process of regional specialization in which the low cost labor in the periphery becomes an attraction for industry. These stages are not inevitable. Government efforts are necessary to develop rural areas in terms of social improvements (education and health), capital infrastructure (transportation and utilities), and fair payments to farmers for their outputs. These seem to be the lessons learned from the industrialization process in Korea, Malaysia, and Taiwan.  相似文献

In this contract-theoretic modelthe government promises a transfer to itspotential opponent in return for notengaging in a civil war. Two causes ofcivil war are identified: (i) imperfectcredibility increases the cost of therequired transfer, and may make itunfeasible; (ii) asymmetric informationfaces the government with the classicefficiency/rent-extraction trade off, andcivil war is used as a screening device.This problem can be solved by creating amixed army. The model determines whether amilitary regime or a redistributive stateprevails in a peaceful equilibrium. Astatistical illustration is presented,using African data.  相似文献

The Central District Council (CDC) in Botswana expanded service delivery to five sub‐districts in January 2000 using a model adapted from the South Somerset District Council, UK. As little data were available on the effectiveness of decentralised service delivery, officials and councillors throughout CDC were interviewed regarding their perception of the process. They not only provided recommendations for enhanced implementation but also identified some of the tensions resulting from it. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

Following World War II (W.W.II), Japan adopted a democratic parliamentary system. Since its formation in 1955 the Liberal Democratic Party (LDP) had monopolized Japanese legislature (Diet) for over 35 years. However, it is said that at the center of the budgetary process was the Ministry of Finance (MOF). Elite bureaucrats rather than politicians are typically seen as the agenda-setter. The action of politicians, in particular members of the LDP, to influence the budgetary resource allocation has been largely unexamined. This paper empirically examines the influence of the LDP on the supplementary budget formation and on the revenue-sharing. We find that the LDP had a significant impact on the budget formation. Further, we find that the LDP manipulated transfers from the central government to local governments presumably to maintain its electoral positions.  相似文献

Merle Bowen's study focuses on the evolution of the ‘middle peasantry’ in both colonial and postcolonial Mozambique. In doing so, she successfully challenges long‐standing, if highly problematic, notions that the Mozambican economy consists of a ‘traditional’, subsistence‐oriented peasant sector with only nominal links to ‘modern’ forms of agriculture, the urban areas, and regional and international markets. At the same time, she usefully illuminates continuities in colonial and post‐independence agrarian policies and shows the ways in which the experience of smallholder agricultural co‐operatives under the Portuguese shaped the peasantry's perceptions of, and responses to, collective agriculture under Frelimo. However, the evidence in Bowen's case study does not necessarily sustain her central thesis that the post‐independence state, like its colonial predecessor, was ‘anti‐peasant’. This is one of several criticisms made of Bowen's text.
