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   

The Use of Augmented Reality Technology in Medical Specimen Museum Tours     

Atsushi Sugiura  Toshihiro Kitama  Masahiro Toyoura  Xiaoyang Mao 《Anatomical sciences education》2019,12(5):561-571

Human anatomical specimen museums are commonly used by medical, nursing, and paramedical students. Through dissection and prosection, the specimens housed in these museums allow students to appreciate the complex relationships of organs and structures in more detail than textbooks could provide. However, it may be difficult for students, particularly novices, to identify the various parts of these anatomical structures without additional explanations from a docent or supplemental illustrations. Recently, augmented reality (AR) has been used in many museum exhibits to display virtual objects in videos captured from the real world. This technology can significantly enhance the learning experience. In this study, three AR-based support systems for tours in medical specimen museums were developed, and their usability and effectiveness for learning were examined. The first system was constructed using an AR marker. This system could display virtual label information for specimens by capturing AR markers using a tablet camera. Individual AR markers were required for all specimens, but their presence in and on the prosected specimens could also be obtrusive. The second system was developed to set the specimen image itself as an image marker, as most specimens were displayed in cross section. Visitors could then obtain the label information presented by AR without any markers intruding on the display or anatomical specimens. The third system was comprised of a head-mounted display combined with a natural click interface. The system could provide visitors with an environment for the natural manipulation of virtual objects with future scalability.  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   

中文电子病历的分词及实体识别研究   总被引：1，自引：0，他引：1  

王若佳  赵常煜  王继民 《图书情报工作》2019,63(2):34-42

[目的/意义]健康医疗大数据是我国重要的基础性战略资源，本研究对中文电子病历分词与实体识别的探讨与实证较好地完成了医疗数据的信息抽取任务，对今后医疗大数据在语义层面的应用发展具有重要意义。[方法/过程]本研究首先融合权威词表、官方标准、健康网站数据及其他医学补充词库构建了词语数量级达到10万的医学词表；然后对电子病历的字段进行分词，对比了jieba工具、导入词典后的jieba、无监督学习及AC自动机4种模型的分词效果；最后，以自动分词和人工标注结果为语料，实现基于条件随机场的电子病历实体识别研究，并比较不同实体类别以及不同文本特征下的实体识别效果，选出最优模板。[结果/结论]分词结果显示，AC自动机的效果最好，F值可达82%；实体识别结果表明，"检查"和"疾病"实体的识别效果最好，而"症状"的识别效果不太理想。  相似文献

科技期刊数字优先出版问题与应对     

原源  戴豪泽 《编辑学报》2016,28(3):279-281

科技期刊数字优先出版较好地解决了出版时滞长、学术论文难以快速出版等问题,加快了科技成果的传播速度.单篇优先灵活性大,出版速度更快;整期优先版面完整,灵活、便捷.纸质期刊出版后不宜覆盖数字优先版本,以解决版本冲突、DOI不确定等问题.同一文献无论数字优先还是纸质版,都应纳入文献引用频次统计.科技期刊出版工作更应强化互联网思维,尽快把数字出版文献纳入学术评价范畴,加强数字优先出版版权保护.无纸化网络出版是大势所趋,未来单篇数字优先出版将逐渐占据数字优先出版主导地位,乃至全部.期待依托网络时速性及大数据、云计算优势,构建独具特色、性格独特的科技期刊,促进学术环境健康发展.  相似文献   

社会心理学视角下的东吴会稽谣言     

陈迪宇 《宁波教育学院学报》2004,6(2):33-36,77

在孙休孙皓统治期间,东吴国内先后爆发了三次事关吴主废立的政治谣言,其中两次发源于会稽郡而另一次也与会稽有关。以社会心理学理论为依据的研究结果表明这三次谣言不是偶然的、孤立的现象。会稽郡在东吴后期存在发生政治性谣言的条件,而且这些谣言的背后隐藏着两个"核心事实":第一,东吴君权更替极不稳定;第二,会稽士族渴望提升自身的政治地位。  相似文献
