中毒死者体内毒鼠强的GC/MS-SIM分析

一 1 9岁男子赌气吞服一白色粉末 ,1 0min后口鼻流血、抽搐 ,迅速送医院 ,经催吐、透析等方法治疗 5天后死亡。根据中毒症状和经验怀疑为毒鼠强中毒。用GC/NPD检验肝中毒鼠强有干扰。改用GC/MS -SIM法分析 ,心血、肝和胃组织中全部检出毒鼠强 ,浓度分别为 0 5 1 μg .mL- 1、0 4 5 μg .g- 1和 0 33μg .g- 1,和文献结果在同一水平。GC/MS -SIM对复杂检材中低含量毒鼠强测定具有更高的选择性 ,也具有较高的灵敏度 ,同时进一步证实毒鼠强排泄较慢 ,经过较长时间后在体内分布比较均匀

论警检关系的基本特征与发展趋势

尽管世界上几个主要国家的警检关系存在三大模式的分野,但各国警察机关和检察机关之间既存在形式上的分工关系,又具有实质上的合作关系,只不过三大模式的侧重点有所不同而已。大致说来,英美模式的侧重点在审判程序,而大陆模式、中俄模式的侧重点在审前程序。但从一些国家近年来的司法改革看,三大模式在相互吸收的基础上,警检关系开始出现紧密化的发展趋势。     

公共部门绩效评估初探

公共绩效可以定义为公共部门在积极履行公共责任的过程中 ,在讲求内部管理与外部效应、数量与质量、经济因素与政治伦理因素、刚性规范与柔性机制相统一的基础上 ,获得的公共产出最大化。公共绩效评估困难的主要原因是管理目标复杂、产品形态特殊、产品标准多维、价格机制缺乏和生产要素独特。绩效评估的核心是建构评估模式 ,评估模式主要包括主题、维度和示标三方面内容     

The impact of downsizing on the corporate reputation for social performance

This paper investigates the impact of downsizing on a firm's reputation for corporate social performance (RCSP). Drawing on the downsizing, corporate reputation and social responsibility literatures, a number of hypotheses concerning the impact of downsizing, and particularly the types of downsizing, on a firm's reputation for corporate social performance are developed and empirically tested. The main findings of this study are that, while downsizing seems to have a negative impact on the firm's RCSP, when one takes into account the kind of managerial action that led to downsizing (layoffs and/or divestitures), this impact differs between the two stakeholder groups, industry executives and financial analysts, which were investigated. This study also found that a high financial performance prior to downsizing led to a greater negative impact on the firm's RCSP. Copyright © 2004 Henry Stewart Publications     

国际金融市场研究方法的逻辑演变——有效市场假说面临的挑战

有效市场假说作为金融经济学的理论基石,无疑是我们研究国际金融市场的重要方法和依据。许多其他得到广泛 应用的金融投资理论皆以此为基础。历经30年的发展,有效市场理论在不断得到支持的同时,也面临了许多新的市场理论的挑 战。混沌理论和分形市场理论,特别是对于市场异象做出新解释的行为金融学,都从不同角度对传统有效市场理论进行了突破。这 不仅为研究国际金融市场提供了新的思路和方法,也对金融市场的决策者和生产者有着巨大的现实意义。     

Livelihood strategies and performance of Ghana's health and education sectors: exploring the connections

The public sector in Africa is riddled with widespread ineffectiveness. Although some countries have implemented various reform programmes with the support of international development agencies, the results so far have been disappointing. One reason for the failure is that the policies have focussed more on achieving macroeconomic stability than making the organisations effective. This article explores a fundamental problem of the policies—the need to focus on the human component of organisational performance. Using education and health organisations in Ghana as examples, the article advances a hypothesis that the livelihood strategies of public sector employees and the performance of their organisations are interconnected. Specifically, it is argued that as public sector employees have become more dependent on multiple sources of income, they have developed multiple social identities, which influence the culture of their organisations. The organisational culture may have encouraged employee effectiveness in some cases, but for most organisations, it has resulted in practices that perpetuate inefficiency and poor performance. To be successful, public sector reform policies must therefore involve deliberate efforts to change organisational cultures. Copyright © 2005 John Wiley & Sons, Ltd.     

Caribbean electricity restructuring: an assessment

This article assesses the privatisation of the electricity sector in two Caribbean countries, Jamaica and Trinidad and Tobago, to determine if they have been successful and whether they have contributed benefits to the respective societies. Two general methods are applied in assessing the success of the divestments; attainment of governments' stated objectives and commonly used utility performance metrics together with social and customer focus indicators. The results indicate that the stated objectives were broadly achieved, and the privatisation and its attempts brought benefits to the consumers and the society in general. The short to medium term benefits were accrued through lower labour costs per unit of electricity, higher performance of plant and operations and business led decision‐making. Long‐term benefits are accrued through the reduction or elimination of electricity supply deficits. However, although the basic privatisations were successful, the absence of an adequate regulatory framework in one case may have reduced the quantum of benefits through failure to enforce continuous improvement in the privatised generation company, and reductions in worker rents in the public distribution company. Further, benefits were reduced by long divestment processes, accompanying strategic drift, opportunity costs from delayed sale proceeds and efficiency enhancement, and the costs to sustain interim operations.
