Using the Information Structure Model to Compare Profile-Based Information Filtering Systems

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher.     

关于三段论一般规则存在依据的思考

三段论理论是人类有史以来第一个真正的理论体系.选择有效式是构造三段论理论重要的一环.三段论一般规则是一种最简单实用的选择方法,但却存在理由不足的缺陷.包含关系的概念内涵之间所具有的蕴涵关系,能够单一地引申或者说充分地论证三段论全部一般规则,甚至能直接识别出三段论每一个具体的有效式,从而为采用一般规则做有效式选择标准的三段论理论提供了可靠的理论依据.     

用信息技术诠释乡土文化——历史文化名城保护与建筑教育的和谐共振

长江大学建筑学专业有两个立足点：其一是历史文化名城荆州深厚的文化底蕴和乡土气息，其二是地方院校建筑教育的生存发展空间。建筑教育应该同本地具体的区域经济、历史文脉、生态环境相结合，利用数字化信息技术研究并促进乡土建筑与自然环境的完美和谐，引导学生探求一种具有乡土特色的建筑创作思想和理念。

The Impact of Museum Purchase on the Auction Prices of Paintings

This study examines how art museumspurchasing policy influences the auction prices ofpaintings. Using a cross section of non-speculativetransactions during the period 1820–1970, we findconsiderable empirical support for the hypothesisthat public museums outside the U.S. pay above averageprices in auction markets providing higher thanaverage yields to private sellers. The typical U.S.private museums appear to be more restricted byfinancial constraints and the development of thegeneral economic conditions than their publiccounterparts.

图书馆评估类型的理论重组

针对学界和业界对图书馆评估类型问题迫切需要进行理论上的重组这一状况，论述图书馆评估在理论上存在着一个开放的类型体系。从图书馆评估的本质属性出发，可以把它划分为鉴定性、建设性、发展性和审美性等实质评估类型;从图书馆评估的外部属性出发，可以把它分别划为广义和狭义、前置性和形成性及总结性、外部和内部、相对和绝对等形式评估类型。     

现代图书馆建筑特色探讨

在信息大量膨胀的时代，不管是传统的图书馆还是以收藏电子出版物为主的图书馆都没有足够的空间来存储不断出现的信息资料。人们会不断需要新的图书馆建筑，图书馆建筑设计师们面临的挑战是如何在不断变化的环境中，建造适应各种需求的多功能建筑。     

渐江绘画艺术形式对安徽建筑景观设计的启迪

渐江曾生活于现今的安徽地域,对安徽的人文风貌在其画作中描绘了许多。渐江的绘画画风笔墨严谨、格调简约,对描绘的自然景物高度概括,虽然用墨偏淡,但不显虚空。画面形式具有现代设计学的韵味,构图独特。这种当时的新视觉形式,不仅影响了中国的山水画,而且也给安徽建筑景观设计在形式和意境方面带来了影响和启示。     

Aiming for autonomy: formative peer assessment in a final-year undergraduate course

This article takes a dual focus on the theme of student formative peer assessment. On the one hand it offers a thorough literature review in this field, while on the other it unpacks a case study of curriculum design where peer assessment has been adopted. The practical example draws on recent changes made to a third- and final-year undergraduate research dissertation course in a UK architectural school. Although peer assessment worked quite well in this small setting, similar findings might be uncovered when scaled up to larger cohorts, as well as other disciplines and year groups. The research findings are certainly relevant for other contexts. Qualitative research from a focus group with six students on the course informs the empirical body of the paper. Through engaging with students’ reflections, as well as the relevant literature, and reflexively looking at the curriculum changes, this paper discusses some of the benefits and drawbacks that can arise from peer assessment in this context. Peer assessment is not without its challenges and hiccups, but, despite these, the benefit to autonomous critical thinking cannot be understated. And arguably peer assessment is especially germane for final-year undergraduates as they embark on employment or more advanced studies.
