体育赛事互补合同的经济分析

从体育赛事存在多种互补合同的事实出发,根据互补性的强弱和市场的竞争状况,将体育赛事互补合同分为6类,并运用不完全信息经济理论的分析框架,对其中的4类逐个进行分析。认为:在这4类合同中不同程度地存在“逆向选择”、“道德风险”、“敲竹杠”和条件信息等问题,导致赛事契约过程中有交易风险大、成功率低、交易费用高等市场失灵的问题,因而有必要创新体育赛事交易制度。     

我国早期公共图书馆的来源研究

以往有关图书馆史的资料多把藏书楼看作为我国公共图书馆的主要来源，认为我国的公共图书馆多由藏书楼演变而来。其实，藏书楼只是公共图书馆的来源之一，在此之外，书院、官书局和个人捐赠也为我国早期公共图书馆的创建，提供了包括馆舍、图书在内的物质基础，因而，同样也是我国早期公共图书馆的重要来源。     

Scale and Translation Invariant Collaborative Filtering Systems

Collaborative filtering systems are prediction algorithms over sparse data sets of user preferences. We modify a wide range of state-of-the-art collaborative filtering systems to make them scale and translation invariant and generally improve their accuracy without increasing their computational cost. Using the EachMovie and the Jester data sets, we show that learning-free constant time scale and translation invariant schemes outperforms other learning-free constant time schemes by at least 3% and perform as well as expensive memory-based schemes (within 4%). Over the Jester data set, we show that a scale and translation invariant Eigentaste algorithm outperforms Eigentaste 2.0 by 20%. These results suggest that scale and translation invariance is a desirable property.     

Conservation Heating 24 Years On

ABSTRACT

Control of relative humidity (RH) for collections care is challenging in U.K. historic houses because they are often highly ventilated with poor heat retention, a porous building fabric and naturally tend to high (60–80%) RH if unheated. The significance of the building means that large-scale modifications and installation of air handling systems may be unfeasible and undesirable for the conservation of the building. In the late 1980s the National Trust, for English, Wales and Northern Ireland, investigated conservation heating as an RH control method that works with the natural environment of historic buildings, mimicking historic heating and requiring only modification of existing heating services or a light touch installation of new heating systems. The National Trust adopted conservation heating as its preferred method for environmental control in historic buildings from the 1990s. This method was presented at the IIC 1994 Ottawa congress on preventive conservation. Conservation heating has since been adopted by many historic house management organisations, particularly across north-west Europe, where it is well suited to the climate. This paper reviews conservation heating developments implemented by the National Trust since 1994, in response to a changing external context, new knowledge and developments in operational practice.     

试论英汉词义的不完全对应关系及其翻译

有的英汉两个词表面上似乎是完全对应的，实际上意义相距甚远，用法各异。本分析了影响这种不完全对应关系的几种因素及这种词语的翻译方法。     

开放式基金的治理机制分析

本运用现代经济学中的不完全合约以及预算软约束两个分析框架对开放式基金的治理机制进行分析，认为基于特殊的信息披露机制以及特有的赎回机制，开放式基金本身独特的合约安排可以自动引致一个有效地解决道德风险与逆向选择等委托代理问题的治理机制。对开放式基金而言，其治理机制的有效性是内生的。正因此，开放式基金具备了蓬勃发展的良好条件。     

不完备信息系统的矩阵约简算法

粗糙集理论是用来解决不确定性的新的数学工具，而知识约简是粗糙集理论中一个重要的研究课题。J．W．Guan等提出了信息系统下的矩阵算法。章则是进一步讨论不完备信息表下的矩阵约简算法，实例表明该算法是有效的，具有一定的应用价值。
