Journal Impact Factor (JIF)

Directory Indexing of International Research Journals

Journals: 2013 | 2012 | 2011 | 2010 | 2009 | 2008

The impact factor (IF) of an academic journal is a measure reflecting the average number of citations to recent articles published in the journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones.

The Impact Factor is calculated by several scientific methods including citation anlaysis

Calculation:

In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years. For example, if a journal has an impact factor of 3 in 2008, then its papers published in 2006 and 2007 received 3 citations each on average in 2008. The 2008 impact factor of a journal would be calculated as follows: A = the number of times that articles published in that journal in 2006 and 2007, were cited by articles in indexed journals during 2008. B = the total number of "citable items" published by that journal in 2006 and 2007. ("Citable items" are usually articles, reviews, proceedings, or notes; not editorials or letters to the editor.)

2008 impact factor = A/B.



(Note that 2008 impact factors are actually published in 2009; they cannot be calculated until all of the 2008 publications have been processed by the indexing agency.)
New journals, which are indexed from their first published issue, will receive an impact factor after two years of indexing; in this case, the citations to the year prior to Volume 1, and the number of articles published in the year prior to Volume 1 are known zero values. Journals that are indexed starting with a volume other than the first volume will not get an impact factor until they have been indexed for three years. Annuals and other irregular publications sometimes publish no items in a particular year, affecting the count. The impact factor relates to a specific time period; it is possible to calculate it for any desired period, and the Journal Citation Reports (JCR) also includes a five-year impact factor.



Editorial policies :

A journal can adopt editorial policies to increase its impact factor. For example, journals may publish a larger percentage of review articles which generally are cited more than research reports. Thus review articles can raise the impact factor of the journal and review journals will therefore often have the highest impact factors in their respective fields. Some journal editors set their submissions policy to "by invitation only" to invite exclusively senior scientists to publish "citable" papers to increase the journal impact factor.

Manuscript Quality

  • Correct page numbers and spelling in the document.
  • Checking text and page numbers in table of contents.
  • Checking and Ensuring tables, figures, references, etc. cited in text
  • Checking lists, paragraphs, figures, etc., numbered or lettered consecutively.
  • Ensuring that there are no duplicate tables and figure titles
  • Checking hyperlinks to references.
  • Reviewing sentences for spelling and grammatical mistakes.
  • Checking style, size, and typeface for headings, titles, bullets etc.
  • Checking of Insertion of appropriate page breaks
  • Ensuring consistent justification for text, callouts, cautions, warnings etc.
  • Choosing correct size and layout of pages.
  • Ensuring consistent use of capitalization and spelling.
  • Applying proper numbering mechanics in the article.
  • Checking format for bibliographic references, i.e. according to any of Citation Style.
  • Using punctuation consistently.

Qualtiy of Publication

  • Citation Counts : The no. of articles cited for respective year of that journal.
  • Journal Discipline : Discipline of the journal.
  • Journals Estimated Importance and Relevance of the Research Field.
  • The journal's presence in various indexing services, directories and listings.
  • The main and important factor is journal publishing regularity.
  • Article Originality : It is the important factor for getting Universal Impact Factor. If Plagairism is detected in articles then the impact factor will be reduced.
