转型时期财政进入或退出竞争性领域问题的新视角

社会主义转型经济时期财政究竟应否进入或退出竞争性领域投资，不仅关系到产业结构的优化升级与所有制结构调整的结合，微观充满活力和宏现协调稳定的结合；更对我国政府经济职能的定位、工业化的完成、市场经济的建设和公有制本质的实现十分重要。分析政府在这一问题选择上的两难境地，并从新的视角解释财政投资于竞争性领域与否的理性选择和合适时机极具理论以及现实指导意义。     

基于知识资产控制权优化配置的创新合作研究

服务外包项目中,顾客与服务供应商之间的创新合作易受知识资产剩余控制权无效配置的限制,已有研究根据GHM模型中的一次性静态博弈分析结论去研究顾客与供应商之间的创新合作,无法有效预测长期合作关系下顾客与供应商建立起信誉机制后,基于重复博弈所做出的行为决策。故建立重复博弈模型,在顾客与供应商之间,基于知识资产剩余控制权优化配置的创新合作问题中引入信誉机制的作用,分析了无限重复博弈和有限重复博弈两种情形下顾客与供应商之间,基于知识资产剩余控制权优化配置的创新合作的实现条件。结论表明,当顾客与服务供应商之间建立起长期合作关系时,信誉机制的作用能够促使外包项目中知识资产的剩余控制权得到优化配置,顾客与供应商之间的创新合作得以顺利进行     

“趣味”的意涵——梁启超对“趣味”的审美阐释

在梁启超那里,趣味是一个区别于他人的、作为特色标识的重要范畴,是包蕴着美本质论、审美心理论、美感效应论、审美价值论等多层面美学思考的美学范畴,内涵丰富而深刻。趣味不仅是区别于真、善而体贴生命本身的美,而且,它同时也是美感体验,是在行动与价值统一基础上形成的、感受到生命自由的美妙感,正是这自由美妙感内在地设定了趣味于生活的意义和价值。     

Reliability functions of bivariate distributions with second kind of beta conditionals

The purpose of this article is to study the bivariate distributions with second kind of beta conditionals, presented by Castillo and Sarabia, from a reliability point of view. The reliability functions, viz the survival function, the failure rate and mean residual life function, are derived and their monotonicity is discussed for the univariate model as well as the conditional model. Finally, Clayton’s association measure is obtained in terms of the hazard gradient and its value, in the case of our model, is derived.     

A New Variant of the Bivariate Setting the Clock Back to Zero Property

Raja Rao et al. (1993 Raja Rao , B. , Damaraju , C. V. , Alhumoud , J. M. ( 1993 ). Setting the clock back to zero property of a class of bivariate life distributions . Commun. Statist. Theor. Meth. 22 ( 7 ): 2067 – 2080 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) introduced the bivariate setting the clock back to zero property. A new variant of this property is introduced that is appropriate for analysing a broader area of practical situations. Some distributions possessing the proposed property are presented. Applications of this property for simplifying the computation of the bivariate mean residual life function and the bivariate percentile residual life function are studied. The relation between the proposed property with the one studied by Raja Rao and Talwalker (1990 Raja Rao , B. , Talwalker , S. (1990). Setting the clock back to zero property of a family of life distributions. J. Statist. Plann. Infer. 24:347–352. [Google Scholar]) and the bivariate lack of memory property is studied.     

A Note on the Regression of Order Statistics

This paper examines the relationships between the mean residual life functions of parallel and k-out-of-n systems with the regression of order statistics. Using these relationships, the results and properties about the mean residual life function of those systems can be used for the regression of order statistics and vice versa. Finally, the paper proposes a definition for the mean residual life function of a k-out-of-n system when the number of failed components of the system is known.     

On Properties of Reversed Mean Residual Life Order for Weighted Distributions

In this article, first, in order to compare X and X ^w (the weighted version of X with weight function w(·)) according to reversed mean residual life order, we provide an equivalent condition. We then try to provide conditions under which the reversed mean residual life order is preserved by weighted distributions. For this end, we obtain several independent results. Finally, the problem of preservation of increasing reversed mean residual life class under weighting is investigated, as well. Some examples are also given to illustrate the results.     

Improved Ordering Results for Fail-Safe Systems with Exponential Components

Let X_{2: n} and Y_{2: m} be the second order statistics from n independent exponential variables with hazards λ₁, …, λ_n, and an independent exponential sample of size m with hazard change to λ, respectively. When m ? n, we obtain necessary and sufficient conditions for comparing X_{2: n} and Y_{2: m} in mean residual life, dispersive, hazard rate, and likelihood ratio orderings based on some inequalities between λ_i’s and λ. The established results show how one can compare an (n ? 1)-out-of-n system consisting of heterogeneous components with exponential lifetimes with any (m ? 1)-out-of-m system consisting of homogeneous components with exponential lifetimes.     

Multivariate Excess Wealth Ordering of Generalized Order Statistics

The concept of generalized order statistics (GOSs) was introduced as a unified approach to a variety of models of ordered random variables. The purpose of this paper is to investigate conditions on the underlying distribution function and the parameters on which GOSs are based, to establish multivariate excess wealth ordering of GOSs from one sample and two samples, respectively.
