A recently suggested modification of the g-index is analysed in order to take multiple coauthorship appropriately into account. By fractionalised counting of the papers one can obtain an appropriate measure which I call gm-index. Two fictitious examples for model cases and two empirical cases are analysed. The results are compared with two other variants of the g-index which have also recently been proposed. Only the gm-index shows the correct behaviour when datasets are aggregated. The interpolated and continuous versions of the g-index and its variants are also discussed. For an intuitive comparison of the determination of the investigated variants of the h-index and the g-index, a visualization of the citation records is utilized.  相似文献

The definitions of the rational and real-valued variants of the h-index and g-index are reviewed. It is shown how they can be obtained both graphically and by calculation. Formulae are derived expressing the exact relations between the h-variants and between the g-variants. Subsequently these relations are examined. In a citation context the real h-index is often, but not always, smaller than the rational h-index. It is also shown that the relation between the real and the rational g-index depends on the number of citations of the article ranked g + 1. Maximum differences between h, hr and hrat on the one hand and between g, gr and grat on the other are determined.  相似文献

Hybrid open access journals generally authorize self-archiving along with Author-pays model. Given the dependence of the Author-pays model on APCs paid by authors, it is expected to have a negative association with the free-of-charge Green model. By exploring a sample of 52,150 papers published in 47 Elsevier's hybrid journals, the study compares the OA models' citation performances to non-open access (NOA) model's and investigates the relationship between the quantities of their papers.Three OA groups are identified, including Green-only, APC-only and Green-APC. The OA papers show a citation advantage over the NOA articles, despite their lower number. The mixed APC-Green, gains the highest citation compared to the three other access models. However, the number of Green and APC-funded papers are revealed to have a negative association. Although, the combination of the Green and APC models magnifies the impact of OA papers, the inverse association between the quantities of their papers signifies that the lower number of the latter can be partially explained by the prevalence of the former. The results help academic librarians involved in advocating and managing OA to better understand authors' behaviors towards OA models and adopt a more supportive role for OA according to their preferences.  相似文献

The arbitrariness of the h-index becomes evident, when one requires q × h instead of h citations as the threshold for the definition of the index, thus changing the size of the core of the most influential publications of a dataset. I analyze the citation records of 26 physicists in order to determine how much the prefactor q influences the ranking. Likewise, the arbitrariness of the highly-cited-publications indicator is due to the threshold value, given either as an absolute number of citations or as a percentage of highly cited papers. The analysis of the 26 citation records shows that the changes in the rankings in dependence on these thresholds are rather large and comparable with the respective changes for the h-index.  相似文献

Vendor evaluation data in online and offline format such as reports varies according to your system. The volume of data is also a key determinant. Advantages and disadvantages of using data obtained from automated systems are compared with those from manual surveys. The paper concludes that statistical data should not be the only input to ongoing supplier evaluation.  相似文献

一般认为,博物馆的基本职能有收集、整理、保管、研究、展览和教育普及等。已故日本博物馆学家鹤田总一郎则进一步将之概括为内部职能、外部职能和综合职能(见下图)。并认为,仅仅从事文物标本的收集、整理、保管和研究工作的机构不是真正的博物馆,而只能称之为保管所、资料馆、考古研究所或文化研究所。若想使博物馆不成为上述机构而成为真正意义上的博物馆,就必须进一步开展展览和教育普及工作,即将内部职能扩展到外部功能。内部职能是外部职能的基础,而外部职能则是内部职能的目的和结果。博物馆工作是一项系统工程,博物馆追求的…  相似文献

出版业的会计学会起步较晚,最近几年各省才相继成立起来,在当地新闻出版局的领导下,在有关部门和单位支持下,工作取得了一定的成绩。但是由于各省出版会计学会(以下称学会)条件的差异,学会工作开展很不平衡,差距很大,有必要对学会成立以来的正反两方的经验作一反思,以便做好今后学会的工作。  相似文献
