Name Disambiguation—Learning From More User-Friendly Models

Library catalogs do not provide catalog users with the assistance they need to easily and confidently select the person they are interested in. Examples are provided of Web services that do a better job of helping information seekers differentiate the person they are seeking from those with similar names. Some of the reasons for this failure in library catalogs are examined. This article then looks at how much information is necessary to help users disambiguate names, how that information could be captured and shared, and some ways the information could be displayed in library catalogs.     

增强现实技术支持下的儿童虚拟交互学习环境研发

增强现实环境中的学习注重虚拟与现实的结合,通过在现实环境之中叠映虚拟三维场景信息,让学习者使用电脑或移动终端在虚实融合的学习环境中交互学习。文章在精要阐述增强现实技术可为儿童构建四种类型的虚实结合的交互学习环境的基础上,以交互式儿童多媒体科普电子书为例,论述基于增强现实的儿童虚拟交互学习环境的结构功能、开发工具、三维模型和标志物的设计及制作、增强现实引擎的实现,以及阅读机理与流程。     

Exploring the Boundary Conditions of the Redundancy Principle

This experiment investigated whether study of a scientific text and a visual display that contained redundant text segments would affect memory and transfer. The authors randomly assigned 42 students from a university in the southwestern United States in equal numbers to 1 of 2 conditions: (a) a redundant condition, in which participants studied a scientific text that described plate tectonics and a corresponding visual display that contained redundant segments from the text; or (b) a nonredundant condition, in which participants studied the scientific text and a corresponding visual display that lacked the redundant text segments. Embedding redundant text segments within the visual display enhanced performance on 3 measures of memory but not on a measure of transfer. The authors discuss the theoretical and practical implications using the cognitive theory of multimedia learning.

中国古代自传文学抒情手法之探微

古代自传是传记学的重要组成部分，也是古人生命情怀的真实写照。与史传相比，古代自传在创作手法上具有淡化史实载述，注重抒情达志的特征，其传主也因此大多人生历史消淡而人格形态生动。古代自传作浓烈的个性张扬的欲望是促成这一学现象产生的根本原因。
