The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
As a rule of thumb, each field should be represented by fewer than ten positions, chosen by their impact factors and other ratings. Note: there are many science magazines that are not scientific journals, including Scientific American, New Scientist, Australasian Science and others. They are not listed here.
Because impact factor is commonly accepted as a proxy for research quality, some journals adopt editorial policies and practices, some acceptable and some of dubious purpose, to increase its impact factor. [38] [39] For example, journals may publish a larger percentage of review articles which generally are cited more than research reports. [8]
The Royal Society have previously identified that "traditional metrics do not fully capture the dynamics of the emerging global science landscape", and that academia needs to develop more sophisticated data and impact measures to provide a richer understanding of the global scientific knowledge that is available to us.
Formats suitable both for reading on paper, and for manipulation by the reader's computer will need to be integrated. [5] [6] Many journals are electronically available in formats readable on screen via web browsers, as well as in portable document format PDF, suitable for
Logo in 2014. The Web of Science (WoS; previously known as Web of Knowledge) is a paid-access platform that provides (typically via the internet) access to multiple databases that provide reference and citation data from academic journals, conference proceedings, and other documents in various academic disciplines.
Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. [1] The ensuing competition between the two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvement in coverage, search/analysis capabilities, but not in price.
Pramana (which in Sanskrit means "source of valid knowledge, a standard") is the outcome of a nationwide effort by Indian physicists to disseminate their best efforts in physics. The journal is published by the Indian Academy of Sciences in collaboration with the Indian National Science Academy and the Indian Physics Association. [1]
