牦牛坪稀土矿区氟碳铈矿与氟碳钙铈矿矿物学

四川省牦牛坪稀土矿区钙稀土氟碳酸盐矿物有氟碳铀矿、氟碳钙铈矿以及笔者发现并命名的牦牛矿。本文旨在简述氟碳铈矿和氟碳钙铈矿的矿物学特征。牦牛坪钙稀土氟碳酸盐类矿物具有强选择轻稀土的特点。其中占９０％以上的氟碳铈矿有两种类型，一种为裂理发育的板状半自形柱状晶体，矿区大量出现。另一种为自形柱状晶体，在矿区极为少见，这种柱状自形氟碳柿矿晶体在自然界中极为罕见。红外吸收光谱表明，氟碳铈矿结构中，具有少量的附加阴离子（ＯＨ）－或者氟碳铈矿中有极少量羟氟碳铈矿。氟碳钙铈矿多为自形晶体，晶面横纹发育，形态多样、典型。但矿区含量甚微。Ｘ射线衍射分析表明，用Ｘ射线苷多菲照相不能分辨钙稀土氟碳酸盐系列矿物经常发育的体衍生多晶现象。     

防止利用关联方交易操纵利润的方法

目前,一些上市公司利用关联方交易操纵利润、粉饰会计报表,造成会计信息的严重失真,为此,规范关联交易定价政策、逐步减少现有可避免的关联交易、制止新的应避免的关联交易产生十分必要。     

海尔“人单合一”管理模式的演化路径及其价值实现机理——基于波粒二象性的理论视域

“人单合一”模式的演化路径可以用“人”“单”之间相互作用关系的变化过程进行描述,这一路径也可概括为“人的价值实现”从无到有地创生涌现,再形成一种独立力量,对“人单合一”体系以及各组织要素进行反向影响和塑造的过程。无论是表面上的二重性特征,还是在内涵层次、演化路径和发展趋势方面,“波粒二象性”与“人单合一”都具有紧密的对应契合性。文章在分析比较“波粒二象性”与“人单合一”对应契合关系的基础上,结合“人”与“单”之间由“分化对立”到“互补转化”再到“整合创新”关系转化的过程,分析阐释了海尔“人单合一”管理模式的演化路径及其价值实现机理。“波粒二象性”不仅为“人单合一”的内涵转变以及发展路径提供了机理解释,而且从跨学科的视角出发,为组织的管理实践与创新变革提供了思路启示。     

构造与市场经济相适应的现代公有制形式

公有制的改革与发展问题是建设有中国特色社会主义经济的核心问题。要完善社会主义初级阶段基本经济制度，实现公有制与市场经济的结合，只在公有制的实现形式上做文章是不够的，还必须高度重视和认其解决公有制本身的存在形式即公有制形式问题。     

An Econometric Estimation of Industrial Water Demand in France

This study investigates the structure of industrial water demand byestimating the derived demand for water on a sample of industrialestablishments located in the south-west of France. Productiontechnologies are represented by short-term variable cost functions andapproximated by a translog form. Industrial water use is modeled ashaving three components: the quantity of water bought to a waterutility, the quantity of autonomous water and the quantity of watertreated prior to use. We include in this framework water effluents,which are considered as a by-product of the production process, emittedby firms. Each of the three water components is treated as a separateinput and all are estimated as a system of simultaneous equations. Themodel is estimated on a sample of 51 industrial plants in the Girondedistrict observed from 1994 to 1996 using Seemingly Unrelated Regression(SUR) and Feasible Generalized Least Squares (FGLS). Results ofestimations show that industrial firms are sensitive to water priceinputs. Network water elasticity is estimated at –0.29. It variesfrom –0.10 to –0.79 according to the type of industryconsidered. Autonomous water price elasticity is not significant.Elasticity for treated water is evaluated at –1.42 at themean-sample and varies from –0.90 to –2.21 according to theindustry considered.

Reduced Form Auctions Revisited

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions, and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite.     

财务会计概念框架的形式转换:冲突及其缓解--兼论《基本准则》的修订及其支撑系统的建构

现阶段我国理论界和准则制定机构主张采取先由<基本准则>充实概念框架部分内容,等到时机成熟后将<基本准则>转化为符合国际惯例的概念框架的两阶段形式转换策略有其合理性.然而,概念框架的理论实质与<基本准则>的会计法规形式之间必然面临冲突.文章分析了这种冲突形成的根源及其影响,并从<基本准则>的修订与支撑系统的建构两个方面提出了缓解上述冲突的一些对策.     

Regulation of Mobile Telephony across the European Union: An Empirical Analysis

In this paper I analyze the impact of regulatory policy on prices and demand for mobile telecommunications services across the European Union. I estimate a reduced form model of the mobile industry using panel data for the EU countries from 1998 to 2002. Among others, I find the following effects: liberalization of fixed telephone lines has a negative impact on prices and a positive impact on the demand for mobile services, and the introduction of mobile number portability has a negative impact on prices.*I am grateful to Toker Doganoglu, Gerd Hansen, Eric Kodjo Ralph, Guido Friebel, participants at the 30th EARIE Conference 2003, the 2nd International Industrial Organization Conference 2004 and the 19th Annual Congress of the EEA 2004, and anonymous referees for valuable comments. I would like to acknowledge the generous financial support from the Volkswagen Stiftung and the Munich Graduate School of Economics which made this research possible.
