书籍装帧中的仿古设计及其审美意蕴     

张杨  李鹏斌 《编辑之友》2018,(8):100-103

仿古书籍装帧设计因其与传统文化密不可分的关联而在现实中大量运用,其设计与渊源大致有几种形式:或完全以古代书籍样式和纸质类型进行装订,或借用线装面貌样式而采用现代的纸张、剪裁和字体,或采用古代书籍的元素符号和表现形态,或成为装饰性的物件.其中所追求的审美意蕴是经典书籍装帧样式所具有的恒常价值,古代书籍装帧审美的现代运用,还包括当下书籍装帧设计审美求新的需要.仿古书籍装帧的艺术形式及其形式美的法则、艺术美的规律是客体存在,内中所蕴含的独特审美意蕴是设计得到普遍认可的内涵所在.  相似文献   

面向学术图书的Altmetrics指标分析     

韩雨彤  周雨涵  杨伟超  刘晓娟 《图书情报工作》2018,62(14):91-97

[目的/意义] 探讨Altmetrics指标对学术图书影响力进行评价的有效性,为学术图书评价工作提出合理建议。[方法/过程] 获取Twitter提及量、Mendeley阅读量、在线书评数量以及馆藏量指标数据,对数据集的覆盖率、分位数等统计量分析后,将被引频数与Altmetrics指标进行了指标间相关系数检验,再对高Altmetrics指标值的学术图书进行年份分布、学科差异及图书主题等实证分析,探究各指标在学术图书影响力评价中的应用。[结果/结论] 传统计量指标被引频数与Altmetrics指标之间的相关性较低,说明Altmetrics可以作为学术图书评价的一个新视角,不同Altmetrics指标反映了学术图书影响力的不同维度。未来的学术图书影响力评价建议结合学术图书的年份、学科等特征,将传统的引文与Altmetrics指标相结合,探索更全面有效的评价机制。  相似文献   

基于LDA主题模型的学术谱系内知识传承研究——以谈家桢为核心的遗传学学术谱系为例     

刘俊婉  杨波  王菲菲  徐硕 《图书情报工作》2018,62(10):76-84

[目的/意义]学术谱系以知识传承的方式助推科学发展。研究知识传承特征,探索学术谱系传承模式及其学术产出影响效能,为探索人才成长规律及人才政策制定提供参考。[方法/过程]基于LDA主题模型,以遗传学领域谈家桢为核心的学术谱系成员发表的期刊文献为研究对象,对该谱系成员的研究主题进行抽取,借鉴生物学"遗传"与"变异"的概念,根据主题相似度将谱系成员划分为"遗传学者"变异学者"和"非遗传非变异学者",并对三种学者的学术绩效进行分析。[结果/结论]分析结果表明,谈家桢学术谱系内"遗传学者"和"变异学者"的学术绩效相对较高;"非遗传非变异学者"的数量占比最多,但学术绩效相对较低;"遗传学者"与"变异学者"在不同主题下的分布具有明显差异。  相似文献   

How U.S. and Chinese journalists think about plagiarism     

Norman P. Lewis  Fan Yang  Yong Zhou 《亚洲交流杂志》2018,28(5):490-507

A comparison of 1,096 professional journalists in China and the United States on attitudes toward attribution and plagiarism reveals Chinese journalists were more likely to see attribution as a practice to be embraced regardless of career longevity and culture, suggesting journalistic norms are more important than a collectivist orientation. Attribution was more likely to be embraced by those who see principles as more important than expediency, affirming research that plagiarism is hardly a monolithic concept. Overall, journalists in the two nations did not vary significantly in their attitudes toward plagiarism, despite vast differences in culture and politics as well as evidence that in some other fields China is more accepting of reusing material without attribution. The data show that among journalists, attitudes toward plagiarism are shared across national boundaries, reinforcing related research showing that a journalism culture exists and is shared at least in part across national boundaries.  相似文献

[目的/意义] 新时代下,跨部门的信息资源共享已经成为加快政府职能转变,提高政府服务效率和透明度的重要事业。明确目前政府信息资源共享有效实施的关键因素,无论对于政府准确把脉行动方向还是学界聚焦政府信息共享的根源性问题都有着重要的意义。[方法/过程] 通过综合集成法梳理出近年来被学界所关注的8个维度的政府信息资源共享影响因素,通过复杂系统DEMATEL模型,构建政府信息资源共享影响因素的关系矩阵。[结果/结论] 经测算,本研究发现11个影响政府信息资源共享实施的关键因素,这些关键因素主要集中在法规政策与标准维度、体制维度、机制维度和技术维度上。  相似文献   

Using word embeddings in Twitter election classification     

Xiao Yang  Craig Macdonald  Iadh Ounis 《Information Retrieval》2018,21(2-3):183-207

Word embeddings and convolutional neural networks (CNN) have attracted extensive attention in various classification tasks for Twitter, e.g. sentiment classification. However, the effect of the configuration used to generate the word embeddings on the classification performance has not been studied in the existing literature. In this paper, using a Twitter election classification task that aims to detect election-related tweets, we investigate the impact of the background dataset used to train the embedding models, as well as the parameters of the word embedding training process, namely the context window size, the dimensionality and the number of negative samples, on the attained classification performance. By comparing the classification results of word embedding models that have been trained using different background corpora (e.g. Wikipedia articles and Twitter microposts), we show that the background data should align with the Twitter classification dataset both in data type and time period to achieve significantly better performance compared to baselines such as SVM with TF-IDF. Moreover, by evaluating the results of word embedding models trained using various context window sizes and dimensionalities, we find that large context window and dimension sizes are preferable to improve the performance. However, the number of negative samples parameter does not significantly affect the performance of the CNN classifiers. Our experimental results also show that choosing the correct word embedding model for use with CNN leads to statistically significant improvements over various baselines such as random, SVM with TF-IDF and SVM with word embeddings. Finally, for out-of-vocabulary (OOV) words that are not available in the learned word embedding models, we show that a simple OOV strategy to randomly initialise the OOV words without any prior knowledge is sufficient to attain a good classification performance among the current OOV strategies (e.g. a random initialisation using statistics of the pre-trained word embedding models).  相似文献

物理课的预习方法     

阳水连 《物理教学探讨》2005,23(24):13

物理课的预习是课堂学习的“添加”和“催化”剂,现给同学们介绍几种预习方法,供参考。1标号法在上新课之前,大家应认真阅读新课,并且在课文中的重点句子下面标符号。例如,在预习《光的直线传播》这一课时,在“光在同一种物质里传播的路线是直的”这句话中“同一种物质”,“直”这六个字下面画小黑点,或画红线。又如在预习《电压》这一课时,对“电压是使自由电荷发生定向移动形成电流的原因”这句话不理解,可在这句话的后面画一个问号,以便上课时集中精力听老师讲解其含义,或者向老师提出此问题,请老师解答。2分析法上新课前同学们应根据本…  相似文献
