目前医学期刊中生存分析的应用十分广泛.在处理生存分析类稿件时,编辑需审查生存曲线是否仅有横纵坐标,生存曲线是否存在交叉,多因素分析时样本量是否足够,多因素分析时变量纳入方法是否正确,多因素分析结果是否完整,RR值、RR 95% CI及P值之间是否一致等.本文详细阐述了上述生存分析中的审查要点,以供编辑人员参考.  相似文献

按照文献计量学有关方法,对2000年以来《编辑学报》的学术影响力进行分析,并采取秩和检验、Spearman(或Kendall)和K-S等方法(检验水准α=0.05)对该刊论文第一作者与论文数量之间的关系进行洛特卡定律的适应性检验。结果:第一作者人数与理论作者人数无差异(Z=1.107,P=0.172),存在相关性(rs=0.914,P0.001(或rK=0.843,P0.001))和一致性(Z=1.171,P=0.129)。说明该刊论文第一作者与论文数量之间的关系与洛特卡定律基本符合。  相似文献

2008年12月修订的《中华医学会系列期刊编排规范》规定:概率用英文大写P(P值前应给出具体检验值,如t值、χ2值、q值等),导致了许多论文中统计学的相关描述比较繁琐,不利于阅读。建议依据2009年颁布的3项相关国家标准修改为:概率用英文大写P(除多组样本的两两比较外,P值前应给出适当的具体检验值,如t值、χ2值、F值等)。  相似文献

期刊编辑在防范学术不端过程中起着重要作用,其一即发现问题。期刊编辑可以在EXCEL中验证统计学结果,以发现统计数据造假;可以利用统计检验量分布值与P值对应规律以及区间值与P值对应规律,发现数据造假。这些方法为防范学术不端体系增加了利器,期待有更多学者发掘相关规律与分享成果。如欲发现论文的数据造假,期刊编辑首先须提高数据审查意识,其次应提升统计学素养与能力。发现数据造假,还必须要求来稿提供统计检验量值与精确P值。在论文评议流程中,建议增设数据与统计学审查流程,以加强对数据的把关力度。  相似文献

典型的PI调节器(即比例积分调节器)是人们熟知的,图1(a)和图1(b)分别给出了它的原理电路和阶跃响应特性.由图可知,当输入量e(t)在t0时刻发生跃变时,输出端立刻出现一个与输入跃变量成正比的调节量|△YP|,这是比例(P)调节所产生的.  相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records.  相似文献

ABSTRACT

The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix.  相似文献

ABSTRACT

The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed.  相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire.  相似文献

ABSTRACT

In today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries.  相似文献

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind.  相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences.  相似文献

ABSTRACT

The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs.  相似文献
