促进城乡和谐发展的理念与理据

城乡差距过大是构建和谐社会的障碍,必须通过"反哺三农"的方式缩小城乡差距,实现城乡间的社会公平与协调发展.从历史贡献补偿角度而言,国民经济应对工业化初期以"剪刀差"方式吸纳的"三农"资金予以补偿;从社会福利角度来说,国民经济的发展不应牺牲涉农主体的利益,政府应对低工资、低地价、农产品低价格予以利益保障或补偿;从社会公正角度而言,政府应保障处于弱势地位的涉农群体的基本权益;从博弈均衡的角度而言,社会公共财政应承担起农村公共品的供给责任.     

How to deal with dissent among experts. Risk evaluation of EMF in a scientific dialogue

This article describes the results of a scientific discourse which aimed at exploring the reasons for differences in expert health risk assessment of radio frequency electromagnetic fields of mobile telephony.

It starts with describing the structure of the discourse. Then, the reasons for the conflicting risk assessments are discussed. Differences are due to the selection and evaluation of relevant scientific studies by applying different scientific quality standards, to the methods used for generating a research synthesis and an overall risk evaluation. Consensus could be achieved regarding the selection of and the quality requirements for the scientific studies used for risk assessment as well as their significance for risk evaluation. However, dissent remained about the synthesis of scientific evidence into an overall risk evaluation and about the relevance of the precautionary principle for risk evaluation and its implications for the risk assessment framework.

Based on the analysis of these problems, a transparent, consistent and rational procedure for risk assessment is suggested to facilitate a risk characterization which better meets the demands of policy making and the public for an appropriate risk evaluation.     

Alcohol abuse among adolescents: regional evidence from Spain

The aim of this paper is to offer regional evidence from Spain on alcohol abuse among adolescents. Specifically, we identify the determinants of the decision to abuse alcohol with respect to the five most important regions of Spain, as well as for the country as a whole. To this end, we estimate Probit specifications using data drawn from the Spanish Surveys on Drug Use in the School Population corresponding to 1994, 1996 and 1998. The results first reveal patterns that are qualitatively similar, but quantitatively different. Similarly, it would appear that economic policies aimed at reducing the access of adolescents to alcohol may have a positive effect on reducing abuse. Finally, the results suggest that encouragement be given to healthy habits among young people, as well as to the fight against education failure and the launching of information campaigns that accurately portray the current lifestyle of adolescents.     

公共部门组织激励存在的问题:西方理论和中国证据

公共部门组织激励是一个非常重要而又困难的问题,近年的研究揭示出公职人员外在激励的有效性天生就不高.原因在于:一是由于激励具有财政约束性,导致政治代理人追求权力最大化,其经济行为效率就低.二是由于委托人目标具有难定性和代理人产出具有难量性,使得可合约性很差,代理人的经济行为缺乏明确的合约条款约束,其道德风险大大增加.上述问题在中国的表现就是地方官员的经济竞争缺乏效率,从中我们也可看出官员内在激励的重要性.     

Trade-offs in audit testing

This case is designed to help you to understand one of the fundamental concepts underlying audits of financial statements: the impact of testing controls on the substantive audit testing to be conducted. When determining the nature, timing and extent of substantive testing, the auditor must consider the costs involved in testing controls and compare that cost to the savings in substantive testing that can occur by relying on the tested controls. In other words, the auditor trades off control testing and substantive testing to determine the best mix of procedures. Similarly, for substantive evidence, the auditor must determine the best mix of substantive analytical procedures and tests of details. In this case, you will assess the trade-offs between the various types of auditing procedures (tests of controls, substantive analytical procedures and tests of details) to determine the optimal audit strategy.     

借贷合同案件的证明责任分配

民事案件证明责任分配不统一的问题引起学术界与司法实务界的关注。与侵权诉讼中的证明责任分配相比,合同纠纷案件的证明责任分配的争议不大。但是对同一案件或同一类案件的证明责任分配,合议庭每个成员或一审和二审或各个法院的判决持己见已经屡见不鲜。尤其是看似简单的借贷合同等案件的证明责任分配意见很难统一。运用具体诉讼具体分析、参考国外先进诉讼制度的方法探究与论证：合同案件中,客观证明责任分配不是考虑分配给原告还是被告,而是以诉讼请求为单位,在债权人和债务人之间分配的。通过验证：以上证明责任分配基准通用于各类合同案件。     

一种改进的证据冲突衡量因子

为解决证据融合时证据间冲突衡量不准确问题,提出了一种新的证据冲突衡量方法。对当前冲突衡量方法国内外研究现状进行总结,结合典型算例分析,指出了当前方法存在的主要问题。基于前人研究成果,提出了一种改进冲突因子用于衡量证据间冲突,主要基于修正证据距离与合取冲突,对两者采用加性组合。通过一般类型算例与特殊类型算例对所提方法进行验证,结果表明改进的冲突衡量因子能够准确衡量证据间冲突,并具有普适性。     

The evaluation of forest crop damages due to climate change. An application of Dempster–Shafer method

In order to assess damage risk caused by climate change in forest areas, Dempster–Shafer theory of evidence and fuzzy measures were applied to develop a framework for the estimation of economic forest damage. According to the definition of risk supported by the Intergovernmental Panel on Climate Change, a function of hazard and resilience lines of evidence was defined. The results of the hazard and resilience assessment were used to develop an economic framework based on Faustmann studies. The evaluation model, implemented through a spatial analysis procedure, was carried out linking Faustmann formula with hazard and resilience raster maps. The model permitted to estimate in monetary terms two possible costs to be supported: the first one is expressed as the expected damage to the forest crop on the basis of the current obtainable woody assortments and the second one referred to the potential expenses to pay in order to mitigate the risk. Finally, the framework was tested on an area of central Italy (Tuscany region).
