The Effect of Web Search Result Display on Users’ Perceptual Experience and Information Seeking Performance

ABSTRACT

Adding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings.

基于HLA的分布式入侵检测系统仿真设计

分布式入侵检测系统（DIDS）是一种分布于网络环境的入侵检测系统,随着网络环境的日益复杂化,DIDS的设计任务也日趋繁重,对系统的仿真是其规划和设计的首要任务。高层体系结构（HLA）是当今世界上非常流行的分布式仿真技术之一,它建立了一个通用的仿真技术框架。基于HLA的仿真应用系统的设计,已经成为当前的研究热点。分析了HLA和DIDS的基本框架,以HLA为基础,借用相关辅助设计软件,对分布式入侵检测系统进行了仿真设计。通过仿真,较好地解决了分布式入侵检测系统的规划和设计方案的复杂性问题,为进一步的实际开发和应用提供了可靠的依据。

Analysis and conservation of modern modeling materials found in Auguste Rodin's sculptures

Prior to the exhibition Portrait-making, Rodin and his models (2009), the Rodin museum wanted to restore two busts of Hanako and Clemenceau. Interestingly, these two sculptures contain pieces of modern modeling materials (MMMs) invented at the end of the nineteenth century as an alternative to clay or waxes. The poor state of conservation of the two portraits made any handling and exhibition impossible. Accordingly, the purpose of this article is twofold: to contribute to technical art history and conservation. Elemental and chemical analyses were done on samples from 12 sculptures (SEM–EDX, FTIR, GC–MS, GC–FID, XRD, synchrotron-based µXRF, µXANES, and µFTIR) aimed at identifying the composition of MMMs used by Rodin on plaster sculptures and establishing hypotheses about the origins of their degradation. This thorough study of their composition and degradation was necessary to implement an appropriate restoration plan. The development of conservation protocols adapted to such materials is rarely documented. Different tests were performed on mock-ups (pH, solubility, adhesion, consolidation, and cleaning). In particular, a protocol based on laser cleaning was developed and successfully applied to remove superficial dust and crusts so that the sculptures regained their original aspect.     

TBL在《现代教育技术》课程教学中的准实验研究

在师范类专业《现代教育技术》公共课程的教学中,在对基于任务学（TBL）进行了前测一后测非对等控制组设计的准实验研究中,通过对实验数据的分析发现：在学生完成学科知识目标方面,TBL与传统讲授法没有显著差异;在学生完成学科技能（设计技能和制作技能）目标方面,TBL与讲授法存在显著差异;在完成调动学生兴趣,进行协作学习方面,两者呈现了显著差异。

农业高校图书馆为现代农业建设提供信息服务探析

在推进现代农业建设大发展的背景下,拥有大量馆藏文献资源和情报人员优势的农业高校图书馆应该积极参与多元化的农技推广服务。但目前农业高校图书馆主要是面向高校本身提供传统借阅服务、以及基于网络和信息增值的信息服务。面对现代农业建设的需求,由于自身的一些原因,农业高校图书馆能够提供的信息服务还不多。为了做好现代农业信息化工作,农业高校图书馆应当转变观念,创新和完善图书馆自身的管理机制、服务模式和服务内容,做强为社会服务的服务品牌,从而在为现代农业建设服务方面走出一条新路子。参考文献3。
