论知识分享   总被引：10，自引：0，他引：10  

周九常 《图书情报知识》2005,(1):28-32,42

应当从综合的角度来理解知识分享的含义。知识分享是知识共享的一个重要条件，问题解决型知识分享是知识分享的主流形式，图书馆的发展史是一部知识分享的演进史，制度安排和信息技术是知识分享不断发展的有力保证，互联网是迄今为止人类所创造的最重要的知识分享工具(系统)，知识分享是共时分享和历时分享的有机统一。  相似文献

吴晓丽  陈广仁 《编辑学报》2018,30(1):92-94

“互联网+”为科技期刊出版行业提供了重大发展机遇,也对科技期刊编辑提出了新的要求.本文探讨科技期刊实施“互联网+”行动的必要性和可行性,认为要有效实施“互联网+”科技期刊行动,编辑须转变工作思维方式,增强互联网意识,强化“把关人”作用,做到全流程和全媒体把关,提高会写、能编、能说、善干等综合能力,才能有效提高科技期刊的国际竞争力.  相似文献   

Evaluation of Internet Information Sources by High School Students in Ghana     

Philip Kwaku Kankam 《International Information and Library Review》2018,50(2):88-93

The Internet clearly presents the opportunity for students to expand their knowledge at a fast pace, since they are able to access enormous amount of information. However, accessing the Internet also has its downside since not all information is of good quality. The study explored how 12th grade students at a high school in Ghana evaluated online information sources. These students and the head of the Information Communication Technology department respond to self-administered questionnaires and a semi-structured interview, respectively. The study found that most of the high school students did some kind of an evaluation of online information sources, however, they were not applying the right criteria. The study further revealed that students were not introduced to evaluation criteria at school and this had contributed to the gap in their evaluation competencies.  相似文献   

A Framework for Policies and Practices to Improve Test Security Programs: Prevention,Detection, Investigation,and Resolution (PDIR)          下载免费PDF全文

Steve Ferrara 《Educational Measurement》2017,36(3):5-23

Test security is not an end in itself; it is important because we want to be able to make valid interpretations from test scores. In this article, I propose a framework for comprehensive test security systems: prevention, detection, investigation, and resolution. The article discusses threats to test security, roles and responsibilities, rigorous training for everyone involved in testing, and an evaluation of current practices in test security. I call on everyone responsible for testing programs—the Association of Test Publishers, Council of Chief State School Officers, National Council on Measurement in Education, U.S. Department of Education, and state assessment program managers, their vendors, and the research community—to collaborate on guidelines and practices for security violation prevention, detection, investigation, and resolution.  相似文献   

基于相对全变分的复杂背景SAR图像舰船尾迹检测     

杨国铮  禹晶  孙卫东 《中国科学院大学学报》2017,34(6):734-742

SAR图像舰船尾迹检测不仅能够反演运动舰船的航速航向信息，也有助于发现图像中弱小的舰船目标。现有的舰船尾迹检测方法对于简单背景SAR图像的检测效果较好，但复杂背景下的检测效果难以满足使用要求。提出一种基于能量泛函极小化的复杂背景SAR图像舰船尾迹检测方法。该方法采用相对全变分技术将图像分解为包含舰船尾迹的光滑成分和海背景纹理成分，通过剪切波变换高频系数重构增强光滑成分，再通过Radon变换检测光滑成分中的尾迹线。比对实验结果表明，本文所提方法对于复杂背景SAR图像的舰船尾迹检测效果明显优于现有的方法。  相似文献   

Impact of digital surge during Covid-19 pandemic: A viewpoint on research and practice     

《International Journal of Information Management》2020

The Covid-19 pandemic has led to an inevitable surge in the use of digital technologies due to the social distancing norms and nationwide lockdowns. People and organizations all over the world have had to adjust to new ways of work and life. We explore possible scenarios of the digital surge and the research issues that arise.An increase in digitalization is leading firms and educational institutions to shift to work-from-home (WFH). Blockchain technology will become important and will entail research on design and regulations. Gig workers and the gig economy is likely to increase in scale, raising questions of work allocation, collaboration, motivation, and aspects of work overload and presenteeism. Workplace monitoring and technostress issues will become prominent with an increase in digital presence. Online fraud is likely to grow, along with research on managing security. The regulation of the internet, a key resource, will be crucial post-pandemic.Research may address the consequences and causes of the digital divide. Further, the issues of net neutrality and zero-rating plans will merit scrutiny. A key research issue will also be the impact and consequences of internet shutdowns, frequently resorted to by countries. Digital money, too, assumes importance in crisis situations and research will address their adoption, consequences, and mode. Aspects of surveillance and privacy gain importance with increased digital usage.  相似文献   

基于负样本多通道优化SSD网络的钢铁厂提取     

卢凯旋  李国清  陈正超  昝露洋  李柏鹏  高建威 《中国科学院大学学报》2020,37(3):352-359

准确提取钢铁厂对去产能监测和环境保护具有重要意义。传统的人工目视解译方法效率低、成本高，无法满足开展大区域钢铁厂监测的需求。以深度学习目标检测网络SSD为基础，构建面向遥感影像钢铁厂提取的深度学习目标检测网络，提出maxout模块，将负样本通路优化为多分支结构，突出难分负样本特征并提升网络对无用特征的抵制效果。利用国产GF-1数据对京津冀地区的钢铁厂进行快速自动提取实验。与人工解译的钢铁厂点位数据的对比表明，该目标检测方法的提取精度达到80%以上。  相似文献
