浅谈我国古代官私书目中的道教典籍     

刘永海 《图书馆杂志》2005,24(9):64-68

道教典籍数量庞大，我国历代官私书目中收录的大量道教典籍，从分类方法和著录范围乃至著录旨趣上，与道经目录都有很大不同；历代官私书目之间在诸多方面也存在差异。通过对古代官私书目的考察，可以更好地了解道教典籍的发展演变和流传情况。  相似文献   

《中国水稻科学》769篇退稿的追踪调查与思考     

职桂叶  阮刘青 《编辑学报》2018,30(4):379-381

为了自查编辑的退稿失误率,提高编辑初审退稿的准确率,兼顾编辑工作效率和期刊质量,调查了《中国水稻科学》2010—2014年间的769篇退稿在他刊的发表情况。截至2017年5月,235篇未发表,534篇退稿在125种刊物上发表,其中92篇退稿发表在影响因子高于1.0的期刊。17篇退稿出现一稿两刊。在刊出的534篇文章中,134篇被引频次为0,102篇被引频次为1,181篇被引频次为2~5,被引频次在10以上的仅有65篇。笔者认为,通过提高编辑的学术素养,增进对专业研究领域的把握,可以减少稿件误判率,做到精准退稿,同时,编辑应掌握沟通技巧,培养亲和力,保证期刊的可持续发展。  相似文献

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers     

Zhigang Hu  Wencan Tian  Shenmeng Xu  Chunbo Zhang  Xianwen Wang 《Journal of Informetrics》2018,12(4):1133-1145

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.  相似文献   

Proximal advantage in knowledge diffusion: The time dimension     

Jue Wang  Liwei Zhang 《Journal of Informetrics》2018,12(3):858-867

This paper intends to explore the impact of geographic proximity on the diffusion of knowledge in the form of publication citations, and argues that codified knowledge is transmitted faster in proximity and is subject to similar geographic constraints as tacit knowledge. The geographic proximity advantage would be particularly relevant in the early stage of dissemination. We collected three sets of research articles published in 1990, 2000 and 2010 and compared the longitudinal citations they received domestically and from abroad. The study found that domestic citations accumulate faster and reach their peak much earlier than foreign citations, and the difference is most evident in the first few years after publication. The result shows that geographic proximity does play a role in the speed of knowledge diffusion and points to the network effect for citations. Those located closer to the knowledge origin would be exposed and react to publications faster due to the additional opportunities of research exchange and network.  相似文献   

Postural stability,clicker reaction time and bow draw force predict performance in elite recurve archery     

Wayne Spratford  Rhiannon Campbell 《European Journal of Sport Science》2017,17(5):539-545

Recurve archery is an Olympic sport that requires extreme precision, upper body strength and endurance. The purpose of this research was to quantify how postural stability variables both pre- and post-arrow release, draw force, flight time, arrow length and clicker reaction time, collectively, impacted on the performance or scoring outcomes in elite recurve archery athletes. Thirty-nine elite-level recurve archers (23 male and 16 female; mean age?=?24.7?±?7.3 years) from four different countries volunteered to participate in this study prior to competing at a World Cup event. An AMTI force platform (1000Hz) was used to obtain centre of pressure (COP) measurements 1s prior to arrow release and 0.5s post-arrow release. High-speed footage (200Hz) allowed for calculation of arrow flight time and score. Results identified clicker reaction time, draw force and maximum sway speed as the variables that best predicted shot performance. Specifically, reduced clicker reaction time, greater bow draw force and reduced postural sway speed post-arrow release were predictors of higher scoring shots. It is suggested that future research should focus on investigating shoulder muscle tremors at full draw in relation to clicker reaction time, and the effect of upper body strength interventions (specifically targeting the musculature around the shoulder girdle) on performance in recurve archers.  相似文献
