This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's ‘citation potential’ defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields. Citation potential is shown to vary not only between journal subject categories – groupings of journals sharing a research field – or disciplines (e.g., journals in mathematics, engineering and social sciences tend to have lower values than titles in life sciences), but also between journals within the same subject category. For instance, basic journals tend to show higher citation potentials than applied or clinical journals, and journals covering emerging topics higher than periodicals in classical subjects or more general journals. SNIP corrects for such differences. Its strengths and limitations are critically discussed, and suggestions are made for further research. All empirical results are derived from Elsevier's Scopus. 相似文献

研究大学生群体新冠疫苗科普信息搜寻意愿影响因素,有助于更好地开展针对该群体的新冠疫苗科普工作。目前,对信息搜寻行为中情感因素影响的研究并不完善,对恐惧的作用缺乏研究。本文采用问卷调查法和结构方程模型对大学生群体新冠疫苗科普信息搜寻意愿影响因素进行分析。研究发现:感知严重性和感知易感性正向影响恐惧;恐惧、态度、主观规范、知觉行为控制正向影响新冠疫苗在线科普信息搜寻意愿;面对新冠疫苗负面信息,女性恐惧感高于男性,年龄与恐惧和搜寻意愿呈显著负相关,女性、人文社科类学生具有更强的搜寻意愿。因此,基于研究提出如下建议:第一,新冠疫苗科普信息传播应以传播科学知识、回应公众关切、缓解公众恐惧为首要目标,切断“信息疫情”的蔓延;第二,可适当采用恐惧诉求,发挥人际传播的作用,以提升大学生新冠疫苗科普信息搜寻意愿;第三,要提升男性搜寻意愿,针对男性和人文社科类大学生开展精准科普,也要缓解女性恐惧感。 相似文献

经济学期刊互引网络的核心-边缘结构分析 总被引：2，自引：0，他引：2
为改进引文分析方法在探测学科期刊群落结构中的应用,以我国经济学期刊为例,运用社会网络分析法中的相关理论与方法,测度经济学期刊互引网络的结构层次。包括利用中心性分析判断该网络存在单一核心,利用核心-边缘模型将期刊互引网络分成从核心到边缘的5个区域。最后将核心度排名结果与CSSCI来源期刊排名相比较,分析了核心度作为期刊评价指标的适用性和优势。认为利用核心-边缘模型可以得出针对任何一个学科门类的期刊核心-边缘分布,并将期刊分层可视化;有助于弥补基于个体属性得出的各种统计指标的不足;可对期刊群进行多层分区,打破核心与非核心的二元划分方式。 相似文献

ABSTRACT This overview of the core concept applied to journals defines the relevant terminology and cites specific examples of core lists. Ten approaches for determining core journals (subjective judgment, use, indexing coverage, overlapping library holdings, citation data, citation network/co-citation analysis, production of articles, Bradford's Law, faculty publication data, and multiple criteria methods) are reviewed and the practical applications of core journals lists are explained. Theoretical and practical problems associated with the core concept and core journal lists are discussed and a taxonomy for classifying core journal lists is outlined. 相似文献

This study investigated information technology (IT) courses offered in American Library Association–accredited library and information science (LIS) programs and the role of faculty with different professional ranks in teaching those courses. More than 20% of the courses offered in 42 programs in the academic year 2002 are IT-related, and 57% of the programs require one particular IT course as part of their core requirements for the master's degree. The contents of the IT courses range widely and go beyond traditional library settings. Faculty with different professional ranks teach significantly different subject areas of the IT courses. Almost half of the junior faculty and more than half of the senior faculty are from multidisciplinary fields; others have a traditional LIS background. Junior faculty's predominant research areas are as follows: information issues; information needs, information-seeking behavior, and information services; cognitive science; systems analysis and evaluation; and information organization. 相似文献

The study explores the publication trends of scholarly journal articles in two core Library and Information Science (LIS) journals indexed under ScienceDirect Database during the period for the period 2000–2010, and for the “Top 25 Hottest Papers” for 2006–2010. It examines and presents an analysis of 1000 research papers in the area of LIS published in two journals: The International Information & Library Review (IILR) and Library & Information Science Research (LISR). The study examines the content of the journals, including growth of the literature, authorship patterns, geographical distributions of authors, distribution of papers by journal, citation pattern, ranking pattern, length of articles, and most cited authors. Collaboration was calculated using Subramanyam's formula, and Lotka's law was used to identify authors' productivity. The results indicated that authors' distributions did not follow Lotka's law. The study identified the eight most productive authors with a high of 19 publications in this field. The findings indicate that these publications experienced rapid and exponential growth in literature production. The contributions by scientists from India are examined. 相似文献

There is an overall perception of increased interdisciplinarity in science, but this is difficult to confirm quantitatively owing to the lack of adequate methods to evaluate subjective phenomena. This is no different from the difficulties in establishing quantitative relationships in human and social sciences. In this paper we quantified the interdisciplinarity of scientific journals and science fields by using an entropy measurement based on the diversity of the subject categories of journals citing a specific journal. The methodology consisted in building citation networks using the Journal Citation Reports® database, in which the nodes were journals and edges were established based on citations among journals. The overall network for the 11-year period (1999–2009) studied was small-world and followed a power-law with exponential cutoff distribution with regard to the in-strength. Upon visualizing the network topology an overall structure of the various science fields could be inferred, especially their interconnections. We confirmed quantitatively that science fields are becoming increasingly interdisciplinary, with the degree of interdisplinarity (i.e. entropy) correlating strongly with the in-strength of journals and with the impact factor. 相似文献

This study investigates the use, citation and diffusion of three bibliometric mapping software tools (CiteSpace, HistCite and VOSviewer) in scientific papers. We first conduct a content analysis of a sample of 481 English core journal papers—i.e., papers from journals deemed central to their respective disciplines—in which at least one of these tools is mentioned. This allows us to understand the predominant mention and citation practices surrounding these tools. We then employ several diffusion indicators to gain insight into the diffusion patterns of the three software tools. Overall, we find that researchers mention and cite the tools in diverse ways, many of which fall short of a traditional formal citation. Our results further indicate a clear upward trend in the use of all three tools, though VOSviewer is more frequently used than CiteSpace or HistCite. We also find that these three software tools have seen the fastest and most widespread adoption in library and information science research, where the tools originated. They have since been gradually adopted in other areas of study, initially at a lower diffusion speed but afterward at a rapidly growing rate. 相似文献

This study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development. 相似文献

The goal of this analysis was to obtain local citation behavior data on undergraduates researching history, political science, and sociology papers. The study found that students cited books and journals even with the availability of web sources; however, usage varied by subject. References to specific websites' domains also varied across subject area. Most of the top journal titles that students referenced were online and locally owned. Students cited a broader range of journal titles than predicted by the Law of Scattering and cited titles across a wide array of subject areas. This data helped identify potential gaps in the library's collection and services. 相似文献

This study investigated changes in the internationality of national publishers' journals for the period 1990–2013. The patterns of foreign and interregional authorship in papers and references of 4,199 journals from 3,529 publishers were analyzed. The results revealed that foreign authorship increased from 36% to 62% during the period, but interregional authorship only grew from 77% to 82%. The growth in internationality is not the same across disciplines and regions of the world. Agricultural sciences, psychiatry/psychology, and economics and business have the least number of foreign authors, while journals in space science, mathematics, and physics have the most. According to the number of both foreign‐authored papers and foreign‐authored citations, clinical medicine is one of the least international fields. Latin America and Middle East publishers have a greater tendency to publish papers from authors in their countries. In contrast, national publishers in North America have become considerably more international over time. Russia, China, and Brazil publish the least number of foreign authored‐papers in their journals, while Switzerland's journals publish the most. 相似文献

Citation analysis provides valuable information on researchers' information use behavior, and helps librarians make evidence-based collection development decisions. However, no citation analysis of faculty publications in the field of communication has been performed to study communication researchers' information use behavior. This study examined communication faculty publication from 2006 to 2014, analyzing format, age, most frequently cited journals, and their subject areas. Analysis of local holdings provides evidence for the library's role in support of faculty research, and helps librarians articulate the value of libraries. 相似文献
