数字对象唯一标志符DOI(digital object identifier),已成为云计算平台上电子文献样本存储和按需服务的最佳应用技术。本文介绍了DOI的发展历史与国际现状,分析了大数据时代期刊DOI的存在意义,特别是2009年JCR新增了eigenfactor score和article influence score 2个评价指标后,DOI已成为评价指标的唯一依据。对2013年300种高校期刊进行了分析,发现其DOI应用比例严重偏低,仅占17.6%,原因有3点:1)期刊无独立网站和过刊回溯功能;2)申请了DOI,但没有针对期刊的文章信息进行注册或在文章上注明DOI;3)期刊网站改版或者网络链接(URL)的变更,没有及时重新注册DOI元数据。建议我国期刊建立数字化平台网站或与国内外大型出版集团合作,在拥有DOI号的同时,同步进行注册,使其成为期刊数字出版的"利器",为广大受众服务,使国内与国外数字出版同步发展。 相似文献

期刊引用认同及其被引评价新指标有效性分析 总被引：2，自引：1，他引：1
以影响因子等引文数据为核心的期刊评价指标体系虽广为使用,但也备受争议.本文从期刊引用认同、期刊被引及期刊国际化等三个方面分析了不仅仅依赖于"影响因子"的评价期刊的新指标,并对相关指标的有效性问题进行讨论.分析表明,基于期刊引用认同视角和基于期刊被引网络视角的很多指标可以与期刊影响因子指标相印证,可用作国内期刊评价的新尝试,而相关期刊国际化评价指标还需在实践中进一步检验. 相似文献

This paper takes the cue from the case of a retracted paper, cited both by the retraction notice and by an article published later in the same journal. This led to analysis and discussion on the skewness of citations in the journal Sustainability and within Multidisciplinary Digital Publishing Institute (MDPI) journals, particularly investigating self‐citations at journal and publisher levels. I analysed articles published by Sustainability in 2015 and found that self‐citations are higher than expected under a uniform probability distribution. Self‐citations in this journal make a 36% difference to the journal's impact factor. This research raises the question of what citation patterns can be expected as normal, and where the boundary between normal and anomaly lies. I suggest the issue deserves further investigation because self‐citations have several implications, ranging from impact factors to visibility and influence of scientific journals. 相似文献

To increase its visibility among the general public and the international scientific community, the Croatian Medical Journal (CMJ), a small journal from the so‐called scientific periphery, introduced a media strategy of sending press releases to journalists and email notices to the newsdesk of a high‐profile international scientific journal. Subsequent news coverage and the positive response of journalists show that press releases and targeted email notices increased international visibility of articles published in a small scientific journal, and improved communication with journalists as mediators of scientific information to the general public. 相似文献

This paper analyses a little-known London newspaper which appeared every week between 1650 and 1661, and which is remarkable for being published in French, as Nouvelles Ordinaires de Londres. The aim is to use this little-known journal to develop new avenues of enquiry regarding print culture in early modern Europe, and to argue that, despite ongoing interest in seventeenth-century journalism, and repeated claims about the need to understand the European context of the English revolution, scholars have been strangely dismissive of this extraordinary journal. My suggestion will be that Nouvelle Ordinaires raises important issues about the commercial, confessional and political forces which influenced the flow of texts across state borders, as well as about novel practices relating to the translation of texts for distribution and consumption on a Europe-wide scale, all of which can be addressed by assessing its audience, its message and its purpose, not least in terms of the newspaper’s multi-vocality. 相似文献

One of the flaws of the journal impact factor (IF) is that it cannot be used to compare journals from different fields or multidisciplinary journals because the IF differs significantly across research fields. This study proposes a new measure of journal performance that captures field-different citation characteristics. We view journal performance from the perspective of the efficiency of a journal's citation generation process. Together with the conventional variables used in calculating the IF, the number of articles as an input and the number of total citations as an output, we additionally consider the two field-different factors, citation density and citation dynamics, as inputs. We also separately capture the contribution of external citations and self-citations and incorporate their relative importance in measuring journal performance. To accommodate multiple inputs and outputs whose relationships are unknown, this study employs data envelopment analysis (DEA), a multi-factor productivity model for measuring the relative efficiency of decision-making units without any assumption of a production function. The resulting efficiency score, called DEA-IF, can then be used for the comparative evaluation of multidisciplinary journals’ performance. A case study example of industrial engineering journals is provided to illustrate how to measure DEA-IF and its usefulness. 相似文献

中国情报学期刊:历史性调整与体系重构 总被引：3，自引：0，他引：3
我国情报学期刊最近几年出现了总量的调整，调整幅度达到２８％。文章从价值取向、情报学学科地位、报刊市场滑坡、宏观调控与组织不力及办刊机构实力等５个方面分析了调整现象产生的客观必然性，认为期刊调整与情报学学科框架的更新形成了同步运动。面对这一变化，情报学期刊应尽快明确调整时期的主要任务，构造其新的体系结构，以保持现有的规模和水平。作者对重新构造后的期刊体系做了设想 相似文献

In a recent paper in the Journal of Informetrics, Habibzadeh and Yadollahie [Habibzadeh, F., & Yadollahie, M. (2008). Journal weighted impact factor: A proposal. Journal of Informetrics, 2(2), 164–172] propose a journal weighted impact factor (WIF). Unlike the ordinary impact factor, the WIF of a journal takes into account the prestige or the influence of citing journals. In this communication, we show that the way in which Habibzadeh and Yadollahie calculate the WIF of a journal has some serious problems. Due to these problems, a ranking of journals based on WIF can be misleading. We also indicate how the problems can be solved by changing the way in which the WIF of a journal is calculated. 相似文献

A new formula for establishing the relationship between the number of papers (n) published in a journal of physics, chemistry or biology and the rank (R) of the journal concerned is proposed. The new formula is straightforward and simple, and appears to lead to a reasonably accurate prediction of the number of published source items in a journal, provided the rank of the journal is known. The proposed formula may be considered as a modification of or alternative to Bradford's law. 相似文献

The NEXIS online system is used a great deal in business and law libraries, but has been virtually overlooked by medical librarians due to their perception of the system as expensive and difficult to search. The changing health care environment has placed new demands on medical searchers for just the type of legal, business, governmental, and news information found in the full-text files in NEXIS. Through the recent introduction of News Pius software, NEXIS can be searched as never before by those unaccustomed to full-text search techniques. Besides simplifying the search process, the new software has cost-savin features since search building and file selection are accomplished offline, and several activities may be done simultaneously. NEXIS via News Plus should be seriously considered as an addition to the repertoire of online systems accessed by medical librarians. 相似文献

[目的/意义] 探索用不同的方法对学术期刊进行评价,以获得更加有效、公平和有价值的信息,促进期刊评价理论与实践的发展。[方法/过程] 将经济学中的自由处置壳（FDH）效率评价模型引入到文献计量学中,对传统FDH模型进行调整,构建一种新的期刊评价方法,选取7个指标对图书情报类的41种期刊进行评价,并将评价结果与其他期刊排名进行相关性分析。[结果/结论] 基于FDH模型的期刊评价方法的评价结果更客观,与其他期刊排名显著相关;该方法将期刊评价指标融合在一起,不仅可以测算出每一个被评期刊的得分,还能够提供更多的有价值的信息,为期刊部门提供决策参考。例如,FDH模型可以识别出被评期刊的"标杆"控制期刊"等,期刊通过与其各指标表现接近的期刊进行对比、分析,发现自身存在的不足和差距,达到持续改进乃至超越的目的。 相似文献

The importance of a scientific journal is usually established by considering the number of citations received by the papers that the journal publishes. In this way, the number of citations received by a scientific journal can be considered as a measure of the total production of the journal. In this paper, in order to obtain measures of the efficiency in the production process, the approach provided by stochastic frontier analysis (SFA) is considered, and econometric models are proposed. These models estimate a frontier production, which is the maximum achievable number of citations to the journal based on its resources. The efficiency can then be measured by considering the difference between the actual production and the estimated frontier. This approach is applied to the measurement of the productive efficiency of the journals of the JCR social sciences edition database, which belong simultaneously to the areas of “economics” and “social sciences, mathematical methods”. 相似文献

《当代北京阅读史话》是一部反映新中国成立以来北京阅读风潮的史话作品,揭示了60多年来北京的沧桑书文化史。这部书别具一格处在于使用了阅读视野来反映文化史,在同类书中有鹤立之姿;然而,对60多年北京阅读历史浓缩式的写作也带来了一些体例上的缺憾,很多阅读例证也有所缺失。瑕不掩瑜,这是部可供研究当代北京文化史甚至我国当代文化史的优秀作品,尤其是它的阅读视角,弥足珍贵。 相似文献
