The use of the Percentage Rank Position index for comparative evaluation of journals

In the present paper the Percentage Rank Position (PRP) index concluding from the principle of Similar Distribution of Information Impact in different fields of science (Vinkler, 2013), is suggested to assess journals in different research fields comparatively. The publications in the journals dedicated to a field are ranked by citation frequency, and the PRP-index of the papers in the elite set of the field is calculated. The PRP-index relates the citation rank number of the paper to the total number of papers in the corresponding set. The sum of the PRP-index of the elite papers in a journal, PRP(j,F) may represent the eminence of the journal in the field. The non-parametric and non-dimensional PRP(j,F) index of journals is believed to be comparable across fields.     

学者评价期刊与引文评价期刊异同之思考——以史学学术期刊评价为例

学者评价期刊与引文评价期刊,各有其优点和局限性,二者有不同和相同之处。将近期史学学者评价史学期刊的结果与CSSCI引文评价的结果对比,二者除具有一定的正相关性外,还具有不同的评价方法和结果,引文评价结果可供学者评价参考。     

医学期刊评论性文章摘要的添加对期刊被引频次的影响

研究医学期刊评论性文章摘要的添加对期刊被引频次的影响。以某杂志为研究对象。该杂志2006年为评论性文章添加了中英文摘要。研究结果显示,与2005年相比,该杂志2006年所发各类文章的总体被引频次及篇均被引频次均下降,尤以论著类文章明显,评论性文章变化不大,不能明确评论性文章摘要的添加对期刊被引频次是否有影响。     

关于利用被引频次支付期刊论文部分稿酬的尝试

目前,国内期刊社关于论文作者稿酬的支付没有统一的标准,有的期刊社不支付稿酬,有的期刊社稿酬支付仍然沿用1999年发布的《出版文字作品报酬规定》,还有些期刊社采取优稿优酬制度,导致作者意见较多。为了更加公平合理地给期刊论文作者支付稿酬,建议国内期刊社可采用基本稿酬+被引频次支付部分稿酬的办法,并就其依据、实施方法、统计被引频次时间范围、不同期刊引用区别对待及其应用的可行性进行分析总结。     

论期刊影响因子人为操纵的识别

近年来,期刊影响因子的人为操纵受到学术界广泛关注,期刊过度自引成为人为操纵影响因子的重要手段.期刊自引率是识别影响因子人为操纵的敏感指标,但对小集团内部期刊互引和其他形式人为操纵的识别却无能为力.在该研究中,深度挖掘了自引率、扩散因子、被引半衰期、开放因子和互引指数在期刊影响因子人为操纵识别中的应用.     

科技期刊总被引频次和影响因子构成中的自引率比较——兼谈影响因子的人为操纵倾向

以2015年自然科学版JCR(S04CR)收录的8 778种期刊为研究对象,计算各期刊总被引频次构成中的自引率(self-citation rate for total citations,RSC,TC)和影响因子构成中的自引率(self-citation rate for impact factor,RSC,IF),全方位比较二者差异程度,揭示不同国家和地区人为操纵期刊影响因子的倾向.结果显示:8 778种期刊集合RSC,TC为0.072,集合RSC,IF为0.112,RSC,TC平均值为0.093,RSC,IF平均值为0.132.排除17种无RSC,IF者,8 761种期刊中,RSC,IF＞RSC,TC者6 954种(79.2％),RSC,TC＞ RSC,IF者1 599种(18.2％),RSC,IF=RSC,TC者208种.Wilcoxon秩检验结果是,Z=59.836,P＜0.001,2组差异有统计学意义.SCI来源期刊中RSC,IF显著高于RSC,TC,捷克、印度、日本、匈牙利和加拿大等国家期刊尤为突出.RSC,IF过度高于RSC,TC,怀疑有人为操纵的可能.     

六种社会科学期刊论文计量研究

运用文献计量学方法对我国六种社会科学期刊2000-2002三年间的全部论文进行了合著类型、著者人数、参考文献、地域分布等多方面计量分析研究.并对社会科学的研究特点进行了探讨.     

Publication delay adjusted impact factor: The effect of publication delay of articles on journal impact factor

The journal impact factor (JIF) has been questioned considerably during its development in the past half-century because of its inconsistency with scholarly reputation evaluations of scientific journals. This paper proposes a publication delay adjusted impact factor (PDAIF) which takes publication delay into consideration to reduce the negative effect on the quality of the impact factor determination. Based on citation data collected from Journal Citation Reports and publication delay data extracted from the journals’ official websites, the PDAIFs for journals from business-related disciplines are calculated. The results show that PDAIF values are, on average, more than 50% higher than JIF results. Furthermore, journal ranking based on PDAIF shows very high consistency with reputation-based journal rankings. Moreover, based on a case study of journals published by ELSEVIER and INFORMS, we find that PDAIF will bring a greater impact factor increase for journals with longer publication delay because of reducing that negative influence. Finally, insightful and practical suggestions to shorten the publication delay are provided.
