The current study uses social network analysis to explore one aspect of cross‐disciplinary connections in community psychology–citations from articles published in community psychology's main journals (i.e., American Journal of Community Psychology and Journal of Community Psychology ) to allied disciplines in 2009. Results indicate that although community psychology journals cited a wide range of disciplines, their levels of citation to any individual journal in another discipline never exceeded 10% of their total network citations. Additionally, journals in other disciplines did not exhibit many citations to community psychology journals. Observed homophily measures indicate that community psychology journals have more cross‐disciplinary citations than articles published in the flagship journals of clinical psychology, sociology, and public health. However, relative homophily measures suggest that community psychology journals are also far more likely to cite within discipline than expected by chance. Implications and future directions for cross‐disciplinary endeavors in community psychology are suggested. 相似文献

Journal impact factors (IF) are often maligned in editorials found in scientific publications, yet citation data can be used
appropriately in journal management. The editors of Laboratory Investigation have found that weekly tracking of citation data
for this and other highly ranked pathology journals provides valuable feedback on editorial performance and enables us to
predict accurate IFs at least six months in advance. Once the IFs are released, it is useful to quantify the contributions
of specific article categories, such as reviews and research articles, to the official IFs. In an ongoing attempt to understand
the relationship between article downloads and eventual citations, we also analyze the citation rate of papers that had previously
been the most frequently accessed on our web site. Finally, as a measure of editorial judgment, the papers that contributed
no citations to the journal’s IF are examined as are the papers that were rejected by Laboratory Investigation (Lab. Invest.)
but subsequently published elsewhere. Thus the editors of Lab. Invest. use citation data in several ways to measure our progress
in elevating the quality of the journal and understand the citation dynamics of papers we publish, while remaining true to
the journal’s fundamental operating premise: Publish high-quality original work relating to the mechanisms of disease. 相似文献

In this article, a critical analysis is performed on differences in citation frequency of basic and clinical cardiovascular
papers. It appears that the latter papers are cited at about 40% higher frequency. The differences between the largest number
of citations of the most cited papers are even larger. It is also demonstrated that the groups of clinical and basic cardiovascular
papers are also heterogeneous concerning citation frequency. It is concluded that none of the existing citation indicators
appreciates these differences. At this moment these indicators should not be used for quality assessment of individual scientists
and scientific niches with small numbers of scientists. 相似文献

According to the Journal Citation Report from the Institute for Scientific Information (ISI), the last year's (2003) impact factor (IF) of the Croatian Medical Journal (CMJ) was 0.943. To determine the factors that contributed to this significant increase in the IF, we analyzed the structure of citations to CMJ in the ISI's publications, Science Citation Index (SCI), and Social Science Citation Index (SSCI). Thematic issues generally acquired more citations than regular issues. Furthermore, citation number varied for different article types. The citations to the original scientific articles corresponded to the average number of citations for the current IF value, whereas reviews and especially case reports were cited less frequently, and negatively contributed to the IF of the journal. Only half of all articles published in two previous years were cited in 2003. The majority of these articles were cited once or twice, whereas only 15 articles received more than three citations. Journal self-citations are still an important contributor to the CMJ's IF (39.6%). Their proportion may decrease in time, by further improving the visibility of the journal, and thus acquiring greater number of independent citations. In future, we can expect year-to-year variations in the journals IF. This trend may be positive on a long-term basis, but expectation of a value significantly higher than 1 is unrealistic. CMJ is small general medical journal whose quality-oriented editorial policy may in the long-term result in the increase in the IF. 相似文献

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has resulted in enormous related publications. However, the citation frequency of these documents and their influence on the journal impact factor (JIF) are not well examined. We aimed to evaluate the impact of COVID-19 on biomedical research publications and their citation frequency.MethodsWe searched publications on biomedical research in the Web of Science using the search terms “COVID-19,” “SARS-Cov-2,” “2019 corona*,” “corona virus disease 2019,” “coronavirus disease 2019,” “novel coronavirus infection” and “2019-ncov.” The top 200 journals were defined as those with a higher number of COVID-19 publications than other journals in 2020. The COVID-19 impact ratio was calculated as the ratio of the average number of citations per item in 2021 to the JIF for 2020.ResultsThe average number of citations for the top 200 journals in 2021, per item published in 2020, was 25.7 (range, 0–270). The average COVID-19 impact ratio was 3.84 (range, 0.26–16.58) for 197 journals that recorded the JIF for 2020. The average JIF ratio for the top 197 journals including the JIFs for 2020 and 2021 was 1.77 (range, 0.68–8.89). The COVID-19 impact ratio significantly correlated with the JIF ratio (r = 0.403, P = 0.010). Twenty-five Korean journals with a COVID-19 impact ratio > 1.5 demonstrated a higher JIF ratio (1.31 ± 0.39 vs. 1.01 ± 0.18, P < 0.001) than 33 Korean journals with a lower COVID-19 impact ratio.ConclusionCOVID-19 pandemic infection has significantly impacted the trends in biomedical research and the citation of related publications. 相似文献

The interests in journal impact factor (JIF) in scientific communities have grown over the last decades. The JIFs are used to evaluate journals quality and the papers published therein. JIF is a discipline specific measure and the comparison between the JIF dedicated to different disciplines is inadequate, unless a normalization process is performed. In this study, normalized impact factor (NIF) was introduced as a relatively simple method enabling the JIFs to be used when evaluating the quality of journals and research works in different disciplines. The NIF index was established based on the multiplication of JIF by a constant factor. The constants were calculated for all 54 disciplines of biomedical field during 2005, 2006, 2007, 2008 and 2009 years. Also, ranking of 393 journals in different biomedical disciplines according to the NIF and JIF were compared to illustrate how the NIF index can be used for the evaluation of publications in different disciplines. The findings prove that the use of the NIF enhances the equality in assessing the quality of research works produced by researchers who work in different disciplines. 相似文献

Citation data accumulated on articles from the top and bottom 25 of impact factor (IF)-ranked international journals are compared
using 59 international geoscience journals from 1998 and 378 Polish geological papers from 1989–1994. There is a minor risk
of being uncited when results are published in high-IF periodicals as the average non-citation rate is 0.88 over a 10-year
period in this not very rapidly developing scientific discipline. Similarly, the established error levels in the prognosis
of expected citation success versus failure based on the extreme IF quartiles as an evaluation tool is low (at most 12.5).
Thus the application of the rank-normalized journal IF as a proxy of real citation frequency and, accordingly, as a predictive
tool in the a priori qualification of recently published publications is a rational time- and cost-saving alternative (or
at least a significant supplement) to traditional informed peer review. Blanket criticism of using IF for decisions in research
funding is therefore at least partly exaggerated.

Inserm is the only French public research institution entirely dedicated to human health. Inserm supports research across
the biomedical spectrum in all major disease areas, from fundamental lab-based science to clinical trials. To translate its
scientists’ findings into tangible health benefits, Inserm has its own affiliated company, Inserm Transfert, which works with
industry. Since 2001, Inserm has been setting up on-line file management software for the evaluation of researchers and laboratories,
called EVA (). EVA includes all grant applications, assessment reports, evaluation grading evaluation forms and includes automated bibliometric
indicator software that enables calculating, for example, the number of publications, journal impact factors, number of citations,
citation index, and number of the Top 1 publications for each researcher of the teams. The indicators take into account research
fields, the year of publications, and the author’s position among the participants. Bibliometrics is now considered a tool
for science policy providing indicators to measure productivity and scientific quality, thereby supplying a basis for evaluating
and orienting R&D. It is also a potential tool for evaluation. It is neutral, allows comparative (national and international)
assessment, and may select papers in the forefront in all fields. For each team, bibliometric indicators are calculated for
all researchers with permanent or long-term positions (3–5 years). The use of bibliometric indicators requires great vigilance,
but according to our experience they enrich the committee’s debates without any doubt. We present an analysis of the data
of 600 research teams evaluated in 2007–2008. 相似文献

IntroductionScientific societies at the undergraduate level contribute to the research training of students. Therefore, the aim of the study is to perform a scientometric analysis of the scientific production of the 27 Scientific Societies of Medical Students (SOCEM) between 2011 and 2020.MethodsA scientometric study of documents in journals indexed in Scopus was performed. A search strategy was developed to identify the scientific production of all SOCEMs with institutional affiliation identifier (AF-ID) in Scopus. Data were extracted using a formula developed with the AF-IDs of each SOCEM and exported to the SciVal tool for analysis.ResultsUrrunaga-Pastor was the author with SOCEM affiliation with the highest number of citations: 92. Four of the five authors of the articles with SOCEM affiliation with the highest number of citations were from the San Fernando Scientific Society (SCSF). The journal with the highest number of papers with SOCEM affiliation was Revista Peruana de Medicina Experimental y Salud Pública. Most of the papers were published in third quartile journals. SCSF was the SOCEM with the highest number of papers: 45, while the Scientific Society of Medical Students of the Universidad de San Martin de Porres (SOCIEM-USMP) had the highest number of citations per paper: 3.9.ConclusionThe number of documents with SOCEM affiliation has been increasing, however, the distribution over the quartiles of the journals has not changed. It’s necessary for public and private institutions to make joint efforts to establish connections to have a greater impact on publications with SOCEM affiliation. 相似文献

The current situation of clinical research in Mexico is analyzed. The main findings are as follows: 10% of total number of researchers in Mexico are engaged in medical research; there is a highly centralized distribution in the Mexico City metropolitan area; there exists unequal academic development among disciplines, and there is an overwhelming number of researchers in public educational and health institutions. A substantial increase in medical publications during the last 15 years with reasonable citation impact was also found. Several urgent matters to attend were identified, such as financing problems, effect of health services descentralization completed in 1997, and the need to selectively support certain research areas such as accidents, mental health, addictions, geriatrics and chronic diseases. 相似文献

Since the establishment of the academic society in 1972, Korean allergists have made continuous efforts to elucidate pathogenic mechanisms and therapeutic advances for allergic diseases. The present study aimed to summarize recent progress and explore future prospects of research performance by Korean allergists. We performed a comprehensive bibliometric analysis for research papers published in the Science Citation Index (SCI) or SCI-expanded journals by Korean allergists between 2009 and 2013. Research performance was quantitatively analyzed for the numbers of papers by publication year, research type, and main topic. In addition, the performance was also examined for qualitative indices, such as impact factor and citation number. A total of 1,091 papers were identified. The number of publication increased continuously, with an annual increase rate of 12.3%. Clinical and basic studies were the most frequent types of research, and recently the number of epidemiological studies has increased. By research topic, asthma was the most commonly studied, accounting for 20.9% of the total number of publications. Notably, the amount of rhinitis/rhinosinusitis research has risen steeply in 2013. Qualitative analyses also indicated continuous progress; the median impact factor of published journals increased from 1.918 in 2009 to 2.746 in 2013, yielding an annual increase rate of 7.4%. In conclusion, the present analyses identified a continuous increase in the research performance of Korean allergists over a recent 5 year period (2009-2013), both quantitatively and qualitatively. A more significant contribution is expected in the forthcoming era. 相似文献

文题释义:
文献计量学:是以文献体系和文献计量特征为研究对象,采用数学、统计学等计量研究方法,研究文献情报的分布结构、数量关系、变化规律和定量管理,进而探讨科学技术的某些结构、特征和规律的一门学科。主要应用于科学出版物评价、科研工作评价、学科发展评价、机构评价等。
CiteScore(CS):即Scopus数据库的核心指标,CS被定义为某期刊前3年发表的文献在统计当年被引用次数除以该刊前3年发表的文献数。CS和JCR中的核心指标影响因子(IF)是同类指标,都是某期刊一定引证时间窗口内论文的篇均被引频次。二者的主要区别有3个方面:①引证时间窗口不同:IF的引证时间窗口为2年,而CS为3年;②IF和CS的分子和分母所包含的文献类型不同:IF分子为期刊所有类型文献被引频次,分母仅计数可被引文献(论文和综述),而CS分母为期刊所有类型文献;③引证数据来源不同:计算IF所用的被引频次来源于WoS,而计算CS所用被引频次来源于Scopus。
