引文国际化对论文被引的影响研究     

龚凯乐  谢娟  成颖  柯青 《图书情报知识》2020,(2):102-112

[目的/意义]在学术交流日趋国际化的背景下,本文拟探索引文国际化与被引量之间的关系,力图回答良好的国际视野是否有助于提升论文的学术影响力这一学界普遍关注的问题。[研究设计/方法]以社会科学为研究对象,选取管理学、图书情报学和新闻传播学的181,406篇CSSCI论文为研究样本,采用相关分析、非参数检验与回归分析的方法研究引用外文期刊论文的数量、学术质量、学科领域、时效性对论文被引量的影响。[结论/发现]在控制了文献类型、期刊声誉等若干可能影响论文被引量的因素后,发现样本论文的引文国际化水平对其被引量具有显著的正向影响。具体而言,引用外文期刊论文的数量越多、平均学术质量越高、学科专属度越高、平均时效性越强的论文具有更高的被引量。[创新/价值]证实了国际视野有助于提升中文社科论文的学术影响力,并提出了有针对性的建议。  相似文献

The emergence of China as a leading nation in science   总被引：4，自引：0，他引：4  

Ping Zhou  Loet Leydesdorff 《Research Policy》2006,35(1):83-104

China has become the fifth leading nation in terms of its share of the world's scientific publications. The citation rate of papers with a Chinese address for the corresponding author also exhibits exponential growth. More specifically, China has become a major player in critical technologies like nanotechnology. Although it is difficult to delineate nanoscience and nanotechnology, we show that China has recently achieved a position second only to that of the USA. Funding for R&D has been growing exponentially, but since 1997 even more in terms of business expenditure than in terms of government expenditure. It seems that the Chinese government has effectively used the public-sector research potential to boost the knowledge-based economy of the country. Thus, China may be achieving the (“Lisbon”) objectives of the transition to a knowledge-based economy more broadly and rapidly than its western counterparts. Because of the sustained increase in Chinese government funding and the virtually unlimited reservoir of highly skilled human resources, one may expect a continuation of this growth pattern in the near future.  相似文献

A novel cell search scheme for OFDM cellular systems     

DING Ming LUO Han-wen WU Yun 《浙江大学学报(A卷英文版)》2007,8(1):10-17

INTRODUCTION Owing to its inherent ability to combat the multi-path fading channel, the modulation technology of orthogonal frequency division multiplexing (OFDM) has been widely used in many high-rate data transmissions such as digital video broadcasting (DVB-T), wireless local area network (IEEE 802.11a) and broadband wireless access (IEEE 802.16e). Re-cently, it is accepted as the most promising candidate for E-UTRA downlink (3GPP TSG-RAN-1, 2006a), which is a super 3G cell…  相似文献   

Frequency of Six Early Childhood Education Approaches: A 10-Year Content Analysis of Early Childhood Education Journal     

Bridget A. Walsh  Karen Petty 《Early Childhood Education Journal》2007,34(5):301-305

The frequency of early childhood education approaches spanning 10 years of publications was investigated. A content analysis of publications (N = 492) from Early Childhood Education Journal was conducted. From a previous content analysis six approaches or search words were identified: Bank Street, Head Start, High/Scope, Montessori, Reggio Emilia, and Waldorf. Overall, the current content analysis demonstrated that the Head Start approach most frequently appeared. The results indicate that approaches vary as to their frequency of appearance and that contributors of Early Childhood Education Journal have investigated, reflected upon, and expanded upon approaches to educating young children to different degrees. This finding may be beneficial to future contributors of Early Childhood Education Journal. In addition, we have provided a brief overview of each approach that early childhood professionals may use to aid parents with their early childhood education enrollment decisions.  相似文献   

基于DDS的“跳点法”信号源设计     

韦燕  李一川  梁向东 《石家庄铁路工程职业技术学院学报》2011,(3):38-42

目前的信号源的设计,大都采用直接数字频率合成技术（DDS）。但在很多情况下,DDS存在最小分辨率为输入时钟1/2~n或采用截断法时噪声增加的问题。设计将介绍一种基于DDS原理,采用＂跳点法＂实现更为精确的频率控制方法。设计采用VHDL语言实现各个模块功能,在QuartusⅡ中完成软件设计与仿真,并下载到cyclone器件中,完成硬件的测试。设计以频率分辨率为基准频率的1%为例,若要获得更高的频率分辨率,只需对程序略加修改即可。  相似文献
