浅谈当代藏族新诗的创作与批评

本文从诗歌批评的角度来研究当代藏族诗歌的创作和发展.鉴于藏族当代诗歌创作与批评相脱节的态势,有必要将创作与批评相结合,创作主体与批评主体相互对话,双向互动进行论述,通过优秀的创作来吸引批评聚焦,通过多元化批评来激励和鞭笞创作,并在文本阐释的基础上突出批评的主体性.     

股权投资企业运营风险的理论探析

以股权投资企业为研究对象,深入分析其经营管理的本质,尝试性地提出了PEF运营风险的定义,并对其具体内容作了概括;通过深入分析PEF的经营管理过程,作者还深入分析了PEF内在的运营机制,并得出初步的研究结果:PEF的运营风险主要集中体现于其资金流动的持续性上,并通过其在资金募集市场、股权投资市场和退出市场的交易成果得到反映。     

国际直接投资收入分配效应的社会福利标准——理论基础、函数测量及其缺陷

经济活动可以通过社会福利判断其效应,资本流动效应则在麦克道格尔模型中得到解释和衡量。国际直接投资作为资本流动的一种特殊经济活动方式,其收入分配效应的福利判断,可以建立在福利经济学的理论基础之上。国际直接投资收入分配效应的社会福利变化,通过柏格森—萨缪尔森方程的变化,在两人两商品的简化模型中,用国际直接投资变量加入前后的差值加以确定。柯布道格拉斯函数为国际直接投资收入分配的计量模型测定提供了基础,可以充分利用时间序列数据,测定国际直接投资收入分配效应所引起的社会福利变化。但就福利经济学的理论基础和演变来看,国际直接投资收入分配效应的福利经济学基础及函数测算,在前提假定及逻辑演变中存在一定的缺陷,主要表现为效用的主观性、外部性产生的福利变化、帕累托最优判断的冲突性问题以及社会福利的合成谬误。因此,国际直接投资收入分配效应的理论运用和实际测算应关注前提假定可能带来的风险和约束。     

民主、信息公开与国家治理模式的变迁

在很长一段历史时间内,信息公开与民主制度并无关联,因为"精英民主"模式通常与保密文化密切相关,它既不鼓励公民参与,也不希望公民知悉政府的信息。直到参与式民主在近几十年取得主流话语权,信息公开才与公共参与一道成为民主制度不可或缺的组成部分。中国《政府信息公开条例》的实施,不仅有利于国家治理模式的转变,而且未来必将有助于民主的发展。     

和谐社会构建中的行政发展价值选择

坚持以人为本、科学发展、改革开放、民主法治、正确处理改革发展稳定的关系以及在党的领导下全社会共同建设等原则,是和谐社会构建对行政发展的基本要求,以公正为基础的市场导向选择是构建社会主义和谐社会行政发展的核心价值要求.     

Construction of Confidence Intervals for the IVIean of a Population Containing Many Zero Values

The likelihood ratio method is used to construct a confidence interval for a population mean when sampling from a population with certain characteristics found in many applications, such as auditing. Specifically, a sample taken from this type of population usually consists of a very large number of zero values, plus a small number of nonzero values that follow some continuous distribution. In this situation, the traditional confidence interval constructed for the population mean is known to be unreliable. This article derives confidence intervals based on the likelihood-ratio-test approach by assuming (1) a normal distribution (normal algorithm) and (2) an exponential distribution (exponential algorithm). Because the error population distribution is usually unknown, it is important to study the robustness of the proposed procedures. We perform an extensive simulation study to compare the percentage of confidence intervals containing the true population mean using the two proposed algorithms with the percentage obtained from the traditional method based on the central limit theorem. It is shown that the normal algorithm is the most robust procedure against many different distributional error assumptions.     

山西黄土CBR的影响分析

在山西省选取5种典型黄土，采用室内试验方法，制备不同击实次数，不同含水量的试件用于CBR值的测定，分析含水量和压实度对黄土填料CBR值的影响，并建立了CBR与含水量的相关关系式。试验结果表明：含水量对CBR值的影响程度最大，在最佳含水量，最大压实度条件下的CBR值最大，含水量越大，击实次数对CBR值的提高效果甚微。随着击实次数的增大，浸水 CBR和不浸水CBR与含水量的相关关系都呈现一定的规律性。     

A Novel Human Error Probability Assessment Using Fuzzy Modeling

Human error is one of the significant factors contributing to accidents. Traditional human error probability (HEP) studies based on fuzzy number concepts are one of the contributions addressing such a problem. It is particularly useful under circumstances where the lack of data exists. However, the degree of the discriminability of such studies may be questioned when applied under circumstances where experts have adequate information and specific values can be determined in the abscissa of the membership function of linguistic terms, that is, the fuzzy data of each scenario considered are close to each other. In this article, a novel HEP assessment aimed at solving such a difficulty is proposed. Under the framework, the fuzzy data are equipped with linguistic terms and membership values. By establishing a rule base for data combination, followed by the defuzzification and HEP transformation processes, the HEP results can be acquired. The methodology is first examined using a test case consisting of three different scenarios of which the fuzzy data are close to each other. The results generated are compared with the outcomes produced from the traditional fuzzy HEP studies using the same test case. It is concluded that the methodology proposed in this study has a higher degree of the discriminability and is capable of providing more reasonable results. Furthermore, in situations where the lack of data exists, the proposed approach is also capable of providing the range of the HEP results based on different risk viewpoints arbitrarily established as illustrated using a real‐world example.
