Citations of this bibliography found by Google Scholar Web pages that link to this bibliography found by Google, scirus phd thesis.
This chronological bibliography is intended to describe progress in reporting these studies; it also lists the Web tools available to measure impact. It is a focused bibliography, on the relationship between impact and access. It does not attempt to cover citation impact, or other related topics such as open access, more generally, although some key papers in these areas are listed as jump-off points for wider study. Added 25 June Björn Brembs, Katherine Button and Marcus Munafò Deep impact: unintended consequences of journal rank Front, scirus phd thesis.
Also in arXiv, scirus phd thesis. On the other hand, much has been written about the negative effects of institutionalizing journal rank as an impact measure. So far, contributions to the debate concerning the limitations of journal rank as a scientific impact assessment tool have either lacked data, or relied on only a few studies.
These data corroborate previous hypotheses: using journal rank as an assessment tool is bad scientific practice. Moreover, the data lead us to argue that any journal rank not only the currently-favored Impact Factor would have this negative impact, scirus phd thesis. Therefore, we suggest that abandoning journals scirus phd thesis, in favor of a library-based scholarly communication system, will ultimately be necessary. This new system will use modern information technology to vastly improve the filter, sort and discovery functions of the current journal system.
Added 25 June Valeria Aman The potential of preprints to accelerate scholarly communication - A bibliometric analysis based on selected journals arXiv. Abstract: This paper quantifies to which extent preprints in arXiv accelerate scholarly communication, scirus phd thesis. The following subject fields were investigated up to the year High Energy Physics HEPMathematics, Astrophysics, Quantitative Biology, scirus phd thesis, and Library and Information Science LIS.
Publication and citation data was downloaded from Scopus and matched with corresponding preprints in arXiv. Furthermore, the INSPIRE HEP database was used to retrieve citation data for papers related to HEP. The bibliometric analysis deals with the growth in numbers of articles published having a previous preprint in arXiv and the publication delay, which is defined as the chronological distance between the deposit of a preprint in arXiv and its formal journal publication.
Likewise, the citation delay is analyzed, which describes the time it takes until the first citation of preprints, and articles, respectively. Total citation numbers are compared for sets of articles with a previous preprint and those without. The results show that in all fields but biology a significant citation advantage exists in terms of speed and citation rates for articles with a previous preprint version on arXiv. Added 21 June Carsten Nieder, Astrid Dalhaug scirus phd thesis Gro Aandahl Correlation between article download and citation figures for highly accessed articles from five open access oncology journals SpringerPlus, 13 June doi When relying on citation counts, one needs to obtain access to citation databases and has to consider that results differ from one database to another.
Accumulation of citations takes time and their dynamics might differ from journal to journal and topic to topic. Therefore, we wanted to evaluate the correlation between citation and download figures, hypothesising that articles with fewer downloads also accumulate fewer citations.
Typically, publishers provide download figures together with the article. We extracted and analysed the 50 most viewed articles from 5 different open access oncology journals. Even if year of publication was taken into account, high correlation coefficients were the exception from the rule.
In conclusion, scirus phd thesis are not a universal surrogate for citation figures. Added 17 June Vincent Lariviere, Cassidy R. Sugimoto, Benoit Macaluso, Stasa Milojevic, Blaise Cronin, scirus phd thesis, Mike Thelwall arXiv e-prints and the journal of record: An analysis of roles and relationships arXiv. Combining data from scirus phd thesis entirety of arXiv and the Web of Science WoSscirus phd thesis, this paper investigates a the proportion of papers across all disciplines that are on arXiv and the proportion of arXiv papers that are in the WoS, b elapsed time between arXiv submission and journal publication, and c the aging characteristics and scientific impact of arXiv e-prints and their published version.
It shows that the proportion of WoS papers found on arXiv varies across the specialties of physics and mathematics, and that only a few specialties make extensive use of the repository. Elapsed time between arXiv submission and journal publication has shortened but remains longer in mathematics than in physics. In physics, mathematics, scirus phd thesis, as well as in astronomy and astrophysics, arXiv versions are cited more promptly and decay faster than WoS papers.
The arXiv versions of papers - both published and unpublished - have lower citation rates than published papers, although there is almost no difference in the impact of the scirus phd thesis versions of both published and unpublished papers.
Added 17 June Pekka Olsbo Does Openness and Open Access Policy Relate to the Success of Universities? pdf Extended Abstract. Introduction: The cross reading and examination of the report The state of scientific research in Finland by The Finnish Academy and Ranking Web of Universities seem to show that there could be a connection between the internet visibility, ranking and the relative citation impact of universities in different countries.
These relationships can be traced back to the effectiveness of the open access publishing, self-archiving and Open Access policies of the countries and the universities. This paper focuses on internet visibility of the University of Jyväskylä and eight European countries and how the openness of universities has developed during last two editions of the Ranking Web of Universities.
Added 17 June Mike Taylor The Challenges of Measuring Social Impact Using Altmetrics Research TrendsIssue 33, scirus phd thesis, June Abstract: Altmetrics gives us novel ways of detecting the use and consumption of scholarly publishing beyond formal citation, and it is tempting to treat these measurements as proxies for social impact, scirus phd thesis.
However, altmetrics is still too shallow and too narrow, and needs to increase its scope and reach before it can make a significant contribution to computing relative values for social impact. Furthermore, in order to go beyond limited comparisons of like-for-like and to become generally useful, scirus phd thesis, computation models must take into account different socio-economic characteristics and legal frameworks.
Occasional series: may have missed In this research, indexes such as the relation between self-citation of journal and impact factor and the effect of self-citation rate of the journal in open access performance are investigated.
Research method is an analytical method conducted by using citation analysis technique. SPSS statistical software was used to examine and analyze the data and its inferential analysis methods such as Pierson Factor were used as well. Statistical society includes journals. The findings indicate that there is a significant relation between self-citation and impact factor.

Snyder The Rich Get Richer and the Poor Get Poorer: The Effect of Open Access on Cites to Science Journals Across the Quality Spectrum Social Science Research Network SSRN, May 25, Abstract: An open-access scirus phd thesis allows free online access to its articles, obtaining revenue from fees charged to submitting authors. Using panel data on science journals, we are able to circumvent some problems plaguing previous studies of the impact of open access on citations.
Open access increases cites to the best content top-ranked journals or articles in upper quintiles of citations within a volume but reduces cites to lower-quality content. We can find structural parameters allowing the model to fit the quintile results quite closely. Added 28 May San Francisco Declaration on Research Assessment DORA American Society for Scirus phd thesis Biology ASCB17 May From DORA: There is a pressing need to improve the ways in which the output of scientific research is evaluated by funding agencies, academic institutions, scirus phd thesis, and other parties.
The Journal Impact Factor is frequently used as the primary parameter with which to compare the scientific output of individuals and scirus phd thesis. The Journal Impact Factor, as calculated by Thomson Reuters, was originally created as a tool to help librarians identify journals to purchase, not as a measure of the scientific quality of research in an article. With that in mind, it is critical to understand that the Journal Impact Factor has a number of well-documented deficiencies as a tool for research assessment, scirus phd thesis.
These limitations include: A citation distributions within journals are highly skewed; B the properties of the Journal Impact Factor are field-specific: it is a composite of multiple, highly diverse article types, including primary research papers and reviews; C Journal Impact Factors can be manipulated or "gamed" by editorial policy; and D data used to calculate the Scirus phd thesis Impact Factors are neither transparent nor openly available to the public, scirus phd thesis.
we make a number of recommendations for improving the way in which the quality of research output is evaluated. A number of themes run through these recommendations: the need to eliminate scirus phd thesis use of journal-based metrics, such as Journal Impact Factors, in funding, appointment, and promotion considerations; the need to assess research on its own merits rather than on the basis of the journal in which the research is published; and the need to capitalize on the opportunities provided by online publication such as relaxing unnecessary limits on the number of words, figures, and references in articles, and exploring new indicators of significance and impact.

To make the case for, or against, a claim such as 'open access increases impact' requires a lot of the reader, who may not be a specialist but scirus phd thesis wants scirus phd thesis try and understand the point at issue and decide if it has any relevance to him or her.
