Impact Factor for Journals
Journal Impact Factor (JIF), a byproduct of citation analysis, is used to group or rank journals according to their relative relevance. Impact Factors (IF) are based on the premise that publications published in journals with high IFs are more likely to be cited than those with low IFs.
Impact variables could be applied by:
Where to submit a piece for publication is up to the authors.
Libraries will decide on collection development.
Academic departments should evaluate the scholarly output
Academic departments will make promotion and tenure decisions.
Where are journal impact factors located?
The annual Journal Citation Reports (JCR) release from Thomson Scientific is the most significant source for journal impact factors.
Impact of the Journal Factor Determined?
The average number of times publications from a journal publish over the previous two years. And they have been mention during the JCR year is the journal impact factor, according to Thomson. The Impact Factor is determine by dividing the total number of articles. And published in the two years prior by the number of citations in the JCR year. The average number of sources for publications posted one or two years ago is one. According to an Impact Factor of 1.0.
An impact factor of 2.5 indicates that, generally speaking, the publications published one or two years ago have received 2.5 citations. Although most citing articles come from special publications, citing reports from the same journal is possible. The number of sources to papers published in 2007 and 2006. In 2008 divided by the total number of articles published in that journal in 2007 and 2006 yields a journal’s impact factor for 2008. Here is how Thomson computed the 2008 impact factor for the journal Academy of Management Review:
As a result, the Academy of Management Review’s 2008 Impact Factor of 6.125 implies that, on average, the papers published in this journal over the previous two years have received roughly 6.125 citations.
Impact factor factors to take into account when consulting:
Date of Publication: The impact factor is based on how often publications from a journal are cited in the first few years after they are published. This isn’t good for journals whose papers are mentioned gradually over time—say, over ten years—instead of instantly. In other words, compared to journals in subjects like education or economics, journals in fast-emerging fields like cell biology and computing tend to have considerably greater instant citation rates, resulting in larger IFs.
Because citations to journal articles are not dispersed equally, the journal impact factor differs from the article impact factor. However, several highly cited papers in a diary could result in a high IF. Even while some journal articles may not be cited at all. As a result, the IF does not represent the calibre of individual journal articles fairly. Journals with additional issues and themes can also have greater Impact Factors. So which may be deceptive because they do not accurately reflect the calibre of the pieces,
Review Articles: Review articles, editorials, letters, and news items are not included in the overall number of pieces but are considered citations for the journal if they are cited (review articles tend to garner more citations). This gives space for manipulating the ratio used to determine impact factors, which can sometimes result in overstated ones.
Clinical Publications: The number of citations in clinical journals is often minimal. As a result, these journals are at a disadvantage to those in the area that publish in research journals with more citations.
Uneven Coverage: The Journal Citation Reports concentrates far more on academic fields where journal articles are the main form of publication. Less coverage is provided for regions in Social Humanities and the sciences. And where books and other forms of publishing are more common.
