CITATION ANALYSIS; RELATIVE IMPACTS; FIELDS; TIME
Abstract:
A consistent and comprehensive ranking of journals relevant for agricultural economists cannot rely on impact factors for at least two major reasons: (i) the scientific database by Thomson Reuters, on which the standard *impact factor* is based, includes only a very limited number of relevant journals; (ii) the standard *impact factor* cannot be compared across research fields of different sizes. Survey-based journal rankings may overcome these problems. We report on such a survey-based ranking initiated by the Agricultural Economics Associations of Germany and Austria. Results of the ranking and a classification of journals, i. e. a rating, are provided for 160 selected journals. Scientific quality is assessed by an index based on the researchers' perception of the quality standards of each journal and of the quality of its published articles. The survey-based ranking allows a much more comprehensive and consistent ranking than the *impact factor*, as specific agricultural !
economics journals can be directly compared with neighbouring economic and interdisciplinary journals to which agricultural economists submit their work. The low impact factors of core agricultural economics journals are put into perspective. The scientific quality of the top agricultural economics journals is assessed as being rather high and above most of the relevant interdisciplinary journals from agricultural and food sciences that are typically characterised by higher impact factors. Agricultural economists' perceptions on the scientific quality of the journals vary more across journals than perceptions of their relevance.

Abstract:
The recent abolition of the ARC journal ranking scheme is indicative of some problematical features of journal ranking in general and the ARC scheme in particular. An alternative citation-based ranking scheme is applied to the accounting and finance journals to highlight some loopholes in the abandoned ARC scheme and provide some suggestions for how to proceed with ERA 2012. By re-ranking journals according to their citation indices, it is demonstrated that the ARC ranking placed a large number of journals where they do not belong. As a result, the ARC scheme induced some adverse behavioural changes with respect to preferred publication outlets.

Abstract:
The purpose of this study was to estimate how many presentations at the Annual Meeting of the Society for Social Work and Research (SSWR) are subsequently published in peer-reviewed journals. A 30% random sample of abstracts presented at the 2006 Annual Meeting of SSWR was reviewed. To determine publication status of the presentations, the authors conducted searches using Google Scholar, PubMed, PsycINFO, and Social Work Abstracts, in addition to reviewing faculty pages and curriculum vitae (CVs). The authors recorded information about the published articles including the journal title, *impact factor*, year, and authors. Forty-three percentage (95% CI = [34.5%, 51.9%]) of presentations were published in a peer-reviewed journal. Twenty-eight percentage (95% CI = [20.9%, 36.7%]) of publications were in a journal with an ISI *Impact Factor* (M = 1.32). The number of presentation authors was not associated with a subsequent publication. No differences were observed by type of p!
resentation.

Abstract:
Evaluating the biomedical literature and health-related websites for quality are challenging information retrieval tasks. Current commonly used methods include *impact factor* for journals, PubMed's clinical query filters and machine learning-based filter models for articles, and PageRank for websites. Previous work has focused on the average performance of these methods without considering the topic, and it is unknown how performance varies for specific topics or focused searches. Clinicians, researchers, and users should be aware when expected performance is not achieved for specific topics. The present work analyzes the behavior of these methods for a variety of topics. *Impact factor*, clinical query filters, and PageRank vary widely across different topics while a topic-specific *impact factor* and machine learning-based filter models are more stable. The results demonstrate that a method may perform excellently on average but struggle when used on a number of narrower !
topics. Topic-adjusted metrics and other topic robust methods have an advantage in such situations. Users of traditional topic-sensitive metrics should be aware of their limitations. (C) 2011 Elsevier Inc. All rights reserved.

Abstract:
Scientific journals are ranked and evaluated to measure their relative importance and influence on science within a specific field. One of the tools most widely used to evaluate and compare journals is the Thomson Reuters *Impact Factor* In Poland a specific value of a scientist's *Impact Factor* is required for academic promotion.
Ginekologia Polska was placed on the Master Journal List in 2008 in the result of changes introduced in 2007 by the new Chief Editor, prof. Marek Spaczynski. In 2010, first time in its history the journal was listed in the Journal Citation Reports with the *Impact Factor* 0.367.
The analysis of Ginekologia Polska contemporary value, as well as of prospects for its development was conducted on the basis of the Journal Citation Reports. In the light of the JCR data, Ginekologia Polska is a highly regarded title compared to other Polish journals. Its value and importance is gradually growing.

IMPACT FACTOR; ANESTHESIA
Abstract:
INTRODUCTION: After submission of a manuscript to a peer-reviewed anesthesia journal, several authors were asked to cite additional references from the journal to which they submitted. We hypothesized that there were differences among the anesthesiology journals in both the total number of self-citations and the proportion of self-citations to the total number of references in each manuscript for the years 2005 and 2010.
METHODS: We conducted a review of a sample of manuscripts from 2005 and 2010 to examine the number and rate of self-citations. As a secondary analysis, we reviewed *impact factor* (IF), rate of self-referencing, and contribution of self-citations to IF in the population of manuscripts published in 8 anesthesia journals between 2000 and 2009 using the ISI Journal Citation Reports.
RESULTS: The number (P < 0.0001) and rate (P < 0.0001) of self-citations among the different journals were significantly different in 2005, with similar results for 2010 in the number (P < 0.0001) and rate (P = 0.0002) of self-citations. The mean range of number of self-citations ranged from 0.45 (95% confidence interval [CI], 0.06 to 0.84) to 3.95 (95% CI, 2.2 to 5.7) in 2005 and from 0.25 (95% CI, -0.05 to 0.55) to 4.5 (95% CI, 2.2 to 6.9) in 2010. On a per-journal basis, no difference in the number of self-citations was noted between 2005 and 2010. Analysis of the ISI Journal Citation Reports from 2000 to 2009 suggested a general decline in the contribution of self-cites to the IF over time for the aggregate journals (Spearman correlation coefficient (Rs) -0.25 (95% CI, -0.45 to -0.03), P = 0.02), with the exception of the journal in question (Rs = 0.59 (95% CI, -0.1 to 0.88), P = 0.05). Positive correlations were found between self-cited rate and IF (Rs 0.52, 95% CI, 0.3!
4 to 0.66, P < 0.0001), percentage of self-cites to years used in IF calculation and IF (Rs 0.41, 95% CI, 0.21 to 0.58, P < 0.0001), and delta-IF and IF (Rs 0.89, 95% CI, 0.84 to 0.93, P < 0.0001).
CONCLUSION: Although the number and rate of self-citations differed among anesthesia journals, the contribution of self-citation to IF has declined over time for most anesthesia journals. These results suggest periodic reassessment may be important to ensure that the publication process remains transparent and impartial to bias. (Anesth Analg 2011; 113: 378-82)

Abstract:
The annual citation counts of 1,172 articles published in 1985 by 13 American Psychological Association journals were analyzed over a 25-year period. Despite a 61% reduction in citation counts from the peak year (1989: Year 4) to the final year (2010: Year 25), many of these articles were still being cited 25 years after they had been published. When the sample was divided into four categories of impact using the total citation counts for each article-low impact (0-24 citations), moderate impact (25-99 citations), high impact (100-249 citations), and very high impact (250-1763 citations)-the yearly citation counts of low to high-impact articles peaked earlier and displayed a steeper decline than the yearly citation counts of very high-impact articles. Using 5 or more citations a years, 10 or more citations a year, and 20 or more citations a year as markers of moderate-impact, high-impact, and very high-impact articles, respectively, and using the most cited articles in a jou!

Abstract:
We investigate the extent to which open-access (OA) journals and articles in biology, computer science, economics, history, medicine, and psychology are indexed in each of 11 bibliographic databases. We also look for variations in index coverage by journal subject, journal size, publisher type, publisher size, date of first OA issue, region of publication, language of publication, publication fee, and citation *impact factor*. Two databases, Biological Abstracts and PubMed, provide very good coverage of the OA journal literature, indexing 60 to 63% of all OA articles in their disciplines. Five databases provide moderately good coverage (22-41%), and four provide relatively poor coverage (0-12%). OA articles in biology journals, English-only journals, high-impact journals, and journals that charge publication fees of $1,000 or more are especially likely to be indexed. Conversely, articles from OA publishers in Africa, Asia, or Central/South America are especially unlikely to !
be indexed. Four of the 11 databases index commercially published articles at a substantially higher rate than articles published by universities, scholarly societies, nonprofit publishers, or governments. Finally, three databases-EBSCO Academic Search Complete, Pro-Quest Research Library, and Wilson OmniFile-provide less comprehensive coverage of OA articles than of articles in comparable subscription journals.

Abstract:
Objective: National arthroplasty registers are often cited as examples of a non-randomized design that have made an essential contribution to advances in assessing arthroplasty procedures. We aimed to compare national registers to randomized controlled trials (RCTs) and meta-analyses in the field of arthroplasty in terms of scientific production and impact.
Method: We systematically searched Medline via PubMed and the registers' websites to select all articles from national registers, RCTs and meta-analyses assessing hip and knee arthroplasty. The scientific production and impact were evaluated by number of publications, number of citations (total and the 3-year citation counts), and information on the 2008 journal *impact factor* (IF), for each design and identified articles. We also contacted representatives of all the selected registers to determine the availability of the data for external research projects.
Results: We retrieved information on 13 active national hip or knee arthroplasty registers; for 9, data were available for research projects under specific conditions. Overall, 190 publications in peer-reviewed journals resulted from national arthroplasty registers, 476 from RCTs, and 40 from meta-analyses. We found 4,112 citations for national register reports, 7,328 for RCT reports and 552 for meta-analysis reports. The median [interquartile [IQR] range] number of citations for register, RCT and meta-analysis reports in the 3-year period after publication was 3.5 [1.0-6.0], 2.0 [1.0-6.0], and 2.5 [0.5-7.5], respectively.
Conclusion: Publications from national registers may have the highest impact among the 3 designs in terms of median citation counts, but data from RCTs remain the most productive evidence in the arthroplasty field. Because of the number of patients recruited by registers, the quality of data collected, and the potential availability of data, scientific production and impact from national registers should be improved.
