Abstract: This study examines the ministerial staff in Australian commonwealth government to discover what they do and how they assist ministers in achieving political control of departments. The data consist of interviews with ministers, departmental secretaries and ministerial staff. The study finds that ministerial staff offer policy advice in much the same way as found by James Walter in his study almost a decade before this one. But there does appear to be more emphasis on monitoring departmental implementation of policy and brokering positions within government than was the case in the earlier study. The study concludes that the relationship between ministers and their offices and the departmental secretaries is characterised by a conditionally cooperative approach, which is similar to that recommended by several public administration scholars.  相似文献

China's reform of government procurement aims to promote greater prudence in expenditure management through introducing transparency, accountability, and competition into the procurement process. The reform can also be construed as China's effort to fulfill its commitment to the WTO. This paper examines the evolution of the reform and measures the success of the reform against three indicators: the amount of cost reduction, the coverage of procurement activities, and the degree of harmonization with the WTO Agreement of Government Procurement. This paper argues that the success of the reform has been limited by an array of factors, including the misconceptions of certain procurement officials and their malpractices in procurement processes, the poor capacities of some local governments in enforcing reform, structural deficiencies in the budget management system, and the lack of political will of both central and local authorities in spurring trade liberalization.  相似文献

This paper examines bilateral cooperation between developed countries (home country) and developing countries (host country) to reduce greenhouse gas emissions and to enhance carbon dioxide sinks. With the home-host country pair as the unit of analysis, our logistic regression model examines 158 Activities Implemented Jointly (AIJ) investment projects from 1993 until 2002 across 2541 country-pairs. Because the marginal costs of reducing emissions may be lower in developing countries, the AIJ projects served as a policy laboratory to assess whether such investments might be advantageous to both countries in the event future regimes allowed emission credits from such bilateral projects. Instead of investing in home countries where maximum pollution reductions (or carbon sequestration) might be possible, home countries invest in locations where they can conduct their policy experiments at low transaction costs. Prior trade and aid relationships were used as a proxy. Regarding energy projects, location decisions are driven by home countries’ desire to reduce air pollution that they receive from abroad. Geography – proximity of a host country to a home country – in interaction with host country's coal production, is a very important driver of location decision in AIJ energy sector projects. Location of sequestration projects is impacted by the host country's potential for avoiding deforestation as well as by previous aid and trade patterns between a home and a host country. Proximity is not important in this case.  相似文献

PENDULUM--a guideline-based approach to the interpretation of STR mixtures   总被引:2,自引:0,他引:2  
Several years ago, a theory to interpret mixed DNA profiles was proposed that included a consideration of peak area using the method of least squares. This method of mixture interpretation has not been widely adopted because of the complexity of the associated calculations. Most reporting officers (RO) employ an experience and judgement based approach to the interpretation of mixed DNA profiles. Here we present an approach that has formalised the thinking behind this experience and judgement. This has been written into a computer program package called PENDULUM. The program uses a least squares method to estimate the pre-amplification mixture proportion for two potential contributors. It then calculates the heterozygous balance for all of the potential sets of genotypes. A list of "possible" genotypes is generated using a set of heuristic rules. External to the programme the candidate genotypes may then be used to formulate likelihood ratios (LR) that are based on alternative casework propositions. The system does not represent a black box approach; rather it has been integrated into the method currently used by the reporting officers at the Forensic Science Service (FSS). The time saved in automating routine calculations associated with mixtures analysis is significant. In addition, the computer program assists in unifying reporting processes, thereby improving the consistency of reporting.  相似文献
