浅谈地市党报楼盘广告话语的人文性

以地市党报自身所具有的较大权威性为研究起点,以其发布的楼盘广告作为研究对象,结合地市党报上所刊登的具体楼盘实例,对楼盘广告话语进行深入剖析。认为当前的地市党报楼盘广告注重以人为本铸造品牌,注重“硬件”人性化和“软件”个性化的转化,其广告话语体现了平民视角和人文关怀,具有鲜明的人文性色彩。     

会计电算化实践中存在的问题与对策

分析了我国会计电算化实践中存在的问题,这些问题包括:领导的重视与支持不够,忽视会计电算化人员的教育,软件功能单一数据共享性差,会计电算化内部管理不规范等。从企业领导、会计人员、财务软件、制度管理等方面提出了改进措施。     

货物运输车辆的调度算法

本文以上海煤炭公司为例,讨论了运煤车辆的计算机调度问题,提出一个数学模型及有效的近似算法。在算法实现中,采用了一些较为先进的数据结构,使运算速度及存储需求均有较大的改善。对实际算例计算结果表明,采用本算法进行运输车辆调度,经济效益比人工调度有明显的提高。     

虚拟社区中的城市：城市微博超话的可沟通性——以重庆微博超话社区为例

当前,城市微博超话研究往往聚焦于趣缘社群,可沟通性价值却被忽略。以重庆微博超话社区为研究对象,抽取400个微博样本,探究城市微博超话蕴含的可沟通城市的潜能和如何运用微博超话机制体现城市传播的三重维度,结果显示：基于信息网络,城市微博超话提供了城市居民寻求社会支持和交往的平台,守城人和城市观察者穿梭在其中;基于地理网络,具身实践书写空间体验,区县印象勾勒立体城市;基于意义网络,城市符号凝聚为城市共同体,城市居民有着“我是本地人”的城市认同。作为虚拟社区中的城市,城市微博超话具有极强的城市属性,体现了可沟通城市“多元融合、时空平衡、虚实互嵌、内外贯通”的内涵。     

Effects of fixed costs in two-person sequential bargaining

Rubinstein (1982) considered the problem of dividing a given surplus between two players sequentially, and then proposed a model in which the two players alternately make and respond to each other's offers through time. He further characterized the perfect equilibrium outcomes, which depend on the players time preferences and order of moves. Using both equal and unequal bargaining cost conditions and an unlimited number of rounds, two experiments were designed to compare the perfect equilibrium model to alternative models based on norms of fairness. We report analyses of final agreements, first offers, and number of bargaining rounds, which provide limited support to the perfect equilibrium model, and then conclude by recommending a shift in focus from model testing to specification of the conditions favoring one model over another.

A Class of Efficient Non-parametric K-sample Tests for Multivariate Counting Processes with Frailties

A K -sample testing problem is studied for multivariate counting processes with time-dependent frailty. Asymptotic distributions and efficiency of a class of non-parametric test statistics are established for certain local alternatives. The concept of efficiency is to show that for every non-parametric test in this class, there is a parametric submodel for which the optimal test has the same asymptotic power as the non-parametric one. The theory is applied to analyse a diabetic retinopathy study data set. A simulation study is also presented to illustrate the theory     

用线性互补及二次规划理论分析市场均衡问题

本文讨论了一类完全竞争条件下的市场均衡问题,供给方的生产特征用线性规划模型进行刻划,市场需求函数源于一般经济意义下的模型,它是一系列相互独立的价格变量的函数．我们将此问题归结为线性互补问题,并依此讨论了均衡点的存在性．本文还讨论了一种用二次规划进行刻划的经济问题,并指出此二次规划的K－K－T条件等价于所讨论的线性互补问题．     

The web proxy location problem in general tree of rings networks

The Web proxy location problem in general networks is an NP-hard problem. In this paper, we study the problem in networks showing a general tree of rings topology. We improve the results of the tree case in literature and get an exact algorithm with time complexity O(nhk), where n is the number of nodes in the tree, h is the height of the tree (the server is in the root of the tree), and k is the number of web proxies to be placed in the net. For the case of networks with a general tree of rings topology we present an exact algorithm with O(kn ²) time complexity.This research has been supported by NSF of China (No. 10371028) and the Educational Department grant of Zhejiang Province (No. 20030622).     

两阶段供应链中三种定价方式研究

本文考虑渠道一体化对品牌建设的作用,在一个制造商和两个零售商的两阶段供应链系统中,其中确定性的市场需求与产品的市场零售价格有关,通过分析以下三种定价方式下的最优定价和库存策略下供应链成员和系统的收益,1)商品市场零售价格由零售商各自决定,两零售商和制造商之间存在着竞争活动;2)商品市场零售价格由制造商统一制定;3)市场零售价格、转让价格和系统库存水平按渠道协调的最优原则确定,确定了同一产品品牌内部的市场竞争、定价控制权及转让价格对渠道性能及品牌自身造成的影响,并由此提出了分散决策系统中的一种激励机制.
