美国联邦政府单一审计制度及其借鉴意义   总被引:1,自引:0,他引:1  
单一审计制度是美国联邦政府的一项重要审计制度。《单一审计法》对美国联邦政府转移支付审计制度进行了详细的规定。本文介绍了单一审计制度,同时结合我国转移支付审计的实际情况,提出了我国在转移支付审计方面应注意的问题,以及如何进一步改进的建议。  相似文献

This paper addresses two very old issues in human society: espionage and double crossing. Our major conclusion points out that there will be a serious over rewarding problem in the direct mechanism due to double crossing in espionage, and a competitive mechanism with a relative performance regime can possibly mitigate the over rewarding problem and still extract the information.   相似文献

We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found.  相似文献

Human lifetimes have increasing failure rates; as people age (beyond early childhood) they are more likely to die. Viewing the succession of Chinese Emperors as a statistical ensemble we show that, unlike lifetimes, their reigns ceased at a constant rate for over two millennia, unaffected by elapsed time. In fact reign lengths of the “Sons of Heaven”, as the Chinese Emperors were known, followed a memoryless exponential distribution with a 10-year half-life. Becoming emperor not only influenced the duration of remaining life, but length of rule was independent of age at ascent. We propose an explanation for the observed exponentiality using asymptotic results from the theory of stationary stochastic processes.  相似文献

结构的耐久性能一直是工程界研究的一个主要问题,在跨海大桥的耐久性设计方面,在国内,目前普遍选择牺牲阳极法作为阴极保护方法,而在国外跨海大桥的防腐保护中,外加电流法已经成为一种最常用的阴极保护方法。本文着重介绍外加电流法的基本原理及在杭州湾跨海大桥中的应用,供其它跨海大桥及港口工程参考。  相似文献

Given the high risk of severe accidents at level crossings (LCs), this study examined legal and illegal crossings by pedestrians and cyclists at a high-traffic LC in Zagreb, Croatia. Survey data and field observations were collected to identify reasons for risky behaviour. Behaviour was observed under normal conditions and in the presence of various safety measures in order to identify measures that can reduce risky behaviour. Results show that the presence of police officer at the LC was most effective at reducing illegal crossings, while the presence of cameras contributes significantly as well, especially after safety educational campaign when illegal crossing decreases for 59.23%. We can assume that in future the improvement regarding human behaviour on LC could be made with cameras on LC and more frequent educational campaigns. This is the first reported use of field survey and video surveillance methods to analyse user behaviour at LCs in Croatia.  相似文献

This paper addresses the question of farmer responses to agri-environmental programming in light of the Single Farm Payment, focusing on the role of environmental regulations and grant schemes in strategic farm decision-making. Utilising Ajzen's theory of planned behaviour in a qualitative case study of farmers in Upper Deeside, Scotland, it was found that farmer respondents actively consider environmental regulations and grant opportunities as part of their decision rationale in making investments in farm development, such as agro-industrial building construction or securing additional land. Fulfilling agri-environmental regulations is constructed by respondents as being part of ensuring farm viability, while eligibility for agri-environmental schemes is impacting on how tenanted land is valued. The author identifies three mechanisms facilitating farmer up-take of environmental schemes, and makes a case for consideration of farmers as experts in producing environmental outcomes while maintaining economic sustainability of farming operations.  相似文献
