Learning technology and disability—Overcoming barriers to inclusion: Evidence from a multicountry study

The paper uses data from a 15-country study to discuss the factors which affect the use of information and communication technologies (ICT) and learning technologies by disabled people and consequently their access to education. Significant differences were found both between and within countries: income and language were the main factors affecting availability. Thus, the greatest availability was in the higher income English-speaking countries and the richer European countries. The main barriers to technology use included cost, lack of funding and lack of information. A particular disparity in technology access was found between the English-speaking European population and Aboriginal speakers of indigenous languages in Australia, with considerably greater access by the former than the latter group. A number of recommendations are presented to increase access to learning and assistive technologies by disabled people. They include encouragement for developers to produce free of charge (minority language) technologies, research on more effective provision of technologies and personal assistance, assistive technology centres in all learning institutions, simple funding mechanisms and a fund to support technology provision in poorer countries.     

SVC bitstream adaptation in MPEG-21 multimedia framework

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil…     

以信息需求匹配为视角的政府信息公开效果评价

[目的/意义]从民众信息需求与信息服务的视角提出政府信息公开效果的评价方法,丰富情报学在政府信息评价中的应用研究。[方法/过程]选取教育、住房、医疗等12个民生相关领域的生活事件,通过不同角度的查询语句模拟人们对上述事件的信息需求。定义匹配率、可见度、覆盖率以及查询平均有效网页数等指标来衡量政府网站公开的信息符合人们需求的情况。结合检索系统和人工筛选共同判断哪些网页符合人们的信息需求。采用全国35个城市政府网站的227万网页数据进行评价实验,评价指标兼顾对内容层面的相关性和评价可操作性的考虑。[结果/结论]本文将信息公开视为政府向民众提供的一种信息服务,根据公开内容所能满足的民众信息需求定义评价指标,衡量信息公开的实际效果。并通过对35个城市政府网站进行不同维度的指标计算得到评价结果,检验了该方法在政府信息公开实际效果评价上的可操作性。

超图的无圈分解问题

引入了超图的无圈分解的荫度的概念,研究了n阶r-完全超图Krn的无圈分解问题,给出了n阶r-完全超图Krn的荫度的一个下界Y(Krn)≥n!/r!(n-r 1)!.并提出猜想T(Krn)={n!/r!(n-r 1)!当[n!/r!(n-r 1)!]=n!/r!(n-r 1)!;n!/r!(n-r 1)! 1,当n!/r!(n-r 1)!≠n!/r!(n-r 1)!.这里[x]表示x的整数部分.     

概括性的立法语言

法律概念具有内涵小外延大的特点。这一特点决定除了必须使用表义明确、具体的立法语言外,还需要表义概括的语言形式。表义概括的名词、行为动词、不定代词和具有名词性的“的”字短语等语言形式可以扩大法律概念的外延,满足法律的需要,是立法语言严谨、周密的保证。
