学术期刊编辑是作者的朋友

学术期刊编辑为提升学术期刊的质量,为期刊的可持续发展注入活力,需要在与作者交往过程中,真诚对待每一位作者,尊重作者,想作者所想,加强沟通,公正无私,把作者当作朋友。这也是编辑良好人文素质的体现。     

The citation evolution law of papers published in the same year but different month

To explore the citation evolution of papers published in the same year but different month, we selected papers from a discipline (physical geography), a subject (diabetes: endocrine and metabolism) and a journal (Journal of Biological Chemistry) published in 2005 as research objects. These papers were divided into six groups according to the difference in publication month, and we analyzed citations to these papers for the 9 years after publication. The results showed that within 5 years after papers from physical geography were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); after that, the differences were not statistically significant. Within 5 years after papers from diabetes (endocrine and metabolism) were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Within 7 years after papers from the Journal of Biological Chemistry were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Citations of papers followed the same pattern irrespective of discipline, subject or journal: citations of papers published in the same year but different month were obviously different in the first few publishing years, but as time went on, only the difference in publication month in a calendar year did not affect the papers' longer‐term citation.     

新形势下高校美术专业图书馆学科资源建设

[目的/意义]学科资源建设是图书馆学科服务的重要组成部分,是提升学科服务质量的基础和前提,是开展学科服务工作的基本保障。图书馆所建设的学科资源是否得到有效的揭示与学科馆员是否可以提供精准服务将直接影响到学科资源最终在用户端产生的学术价值。本文通过梳理美术学科资源建设内容及方法,总结图书馆专业学科资源建设解决方案,为专业学科服务贡献力量。[方法/过程]调研美术专业各级学科的内容设置,详细分析其学科特点及文献资源需求特点,提出美术专业学科资源建设内容、建设制度、建设形式与评价方式,利用Libguides学科资源导航平台对美术学科资源进行有效的组织揭示。[结果/结论]从美术专业学科资源建设出发,提出美术专业资源建设与揭示的具体流程和内容,对各类型专业图书馆的资源建设具有很好的借鉴意义。     

Acute kinematics changes in marathon runners using different footwear

The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes.
