教育——跨越“数字鸿沟”的桥梁   总被引:2,自引:0,他引:2  
信息技术狂飙突进般的发展,把整个社会从工业时代一下子推进到信息时代,使我们的生活从休闲娱乐到学习工作都发生了巨大的变化。令人们迷惑不解的是,科学技术,特别是信息技术作为最先进的社会生产力,并没有缩小发达与落后、富有与贫穷的差距,由0和1堆砌而成的地平线迅速地坍塌、下陷,形成了一条难以逾越并且还在不断扩大的数字鸿沟。 幸亏,教育,是跨越这道数字鸿沟的桥梁。  相似文献

只有亲身走进山西,你才能发现它的文化之久远、资源之丰厚,然而那些都是历史与大自然所赐,现实中的山西给人更多的感受却是贫瘠。本来,在我们这样一个油、气资源相对短缺的国度里,山西极为丰富的煤炭资源无疑是一笔巨大的财富,应当能够带动区域经济的高速发展,以及社会与文化的进步,然而到山西走上一圈才会发现,煤在这里发挥的作用其实并不尽如人意。山西或许并不很封闭,然而却比较落后,寻找产生这种现象的原因,我们发现,信息化既是一种表象,也是症结之一。  相似文献

数字鸿沟概念是在1996年克林顿竞选总统时,由戈尔正式提出一个概念,不过,数字鸿沟现象当时却并没有在美国出现。这是和当时美国克林顿总统倡导从教育和接入互联网的角度来解决数字鸿沟问题分不开的,例如推进不发达地区的计算机教育,要求全美每个小学都要上网,在穷人区要求互联网免费,政府资助图书馆等公共设施所有人可以免费上网。  相似文献

The purpose of this article is to explore stakeholders’ perspectives on the relative advances of digital preservation management over traditional heritage management approaches in developing countries, particularly in Africa. Specific examples from the context of Ghana are used to help understand the particular factors that influence the relative advantage of the digital preservation management innovation. The article is based on the findings of a PhD study that explored contextual factors influencing the management and preservation of digital cultural heritage resources in Ghana and it is underpinned by Rogers’ Diffusion of Innovation model. An interpretive qualitative approach was employed to solicit the perspectives of 29 key stakeholders from 13 institutions in Ghana through semi-structure interviews. This was followed by an analysis of relevant literature to ascertain how the findings from the context of Ghana relate to other developing countries in Africa.

Stakeholders perceive that the digital preservation management innovation has relative advantages over other traditional ways of managing and preserving heritage information in many ways, including; as an effective means to manage cultural heritage resources; enhancing collaboration and resource sharing; contributes to the building strong cultural institutions; leading to the establishment of a national digital memory for developing countries; as an effective means to preserve value of cultural identity for the long term into the digital future; and enabling research and advancement of cultural knowledge.

Findings from the literature analysis also show that these relative advantages of the digital preservation management (DPM) innovation occur in similar forms in other developing countries in Africa. Further empirical studies in other developing countries are recommended to fully ascertain the main relative advantages of the DPM innovation over traditional approaches of heritage resources management and preservation.  相似文献

基于分治法的快速确定规则获取算法   总被引:2,自引:0,他引:2  
值约简是Rough集理论研究的一个重要内容,目前已有的算法很难快速处理大数据集。文中通过在属性空间上对论域对象的分解,提出一种基于分治法的快速确定规则获取算法,并给出实例说明。该算法可直接从离散的决策表获取确定决策规则,在数据服从均匀分布的条件下,算法的时间复杂度低于n2,适合大数据集的确定规则获取。实验结果说明算法的高效性。  相似文献

Today, highly sophisticated technology has changed the lives of most individuals worldwide. In the field of graphic design, the emergence and developmentof digital multimedia communication forms have had a crucial impact on the creative process of graphic design and even the process of communication,offering more opportunities and more exciting challenges to this domain. And with the continuous improvement of people’s material culture and spiritualculture, the digital age has enriched people’s production and life. Especially in the application of digital multimedia in graphic design, the changes causedby the emergence of digital multimedia focus mainly on the visual expression. With the continuous application of digital multimedia communication forms,the graphic design closely related to it has been affected to some extent. In order to meet the changing data needs of people, graphic design has also begunto adjust accordingly. Therefore, this paper analyzes the relationship between digital multimedia and graphic design from the perspective of art design,systematically determines the relationship between multimedia and graphic design specific design subjects, and studies the influence of digital multimediatechnology on graphic design.  相似文献

This study explored the interplay between contextual and individual factors related to Internet adoption in isolated rural communities. By investigating 10 remote villages throughout Chile that received Internet access infrastructure in 2010–2011, we identified 3 areas in which contextual and individual factors are intertwined. First, the geographical isolation shaped people's personality and attitudes towards new experiences, including digital technologies. Second, the communities' aging population also represented a strong challenge because they lack young people, a relevant technology socialization agent. Finally, jobs and economic activities are related to people's (lack of) motivations and needs towards digital technologies. When the Internet has reached the vast majority of the population, isolated communities confront specific challenges that we need to consider in policy‐making decisions.  相似文献
