Abstracting And Indexing
The CiteScore of Journal of Midwifery is calculated as: 0.0 (Click Here for more information)
Several journal metrics are calculated. The first metric is an alternative impact factor which is based on Google Scholar’s citation count.
The journal impact factor (JIF) normally referred to is the proprietary journal impact factor from Thomson Reuters calculated based on the Web of Science (WOS) and published in the Journal Citation Reports® (JCR). We call this the JCR®JIF. DOAJ writes: “There is only one official, universally recognized impact factor that is generated by Thomson Reuters; it is a proprietary measure run by a profit-making organization. It runs against the ethics and principles of open access.” This journal has no JCR®JIF, but an alternative Google-based impact factor.
Today 80% of readers find their way to Journal of Midwifery articles via Google Scholar. No open or proprietary database is directing so many readers to articles. Google Scholar is the only openly available database suitable for journal metric calculation. It has a wide coverage and is a meaningful source. For this reason, Journal of Midwifery is calculating its own Impact Factor based on Google Scholar’s citation counts. Scientists are used to Thomson Reuters’ way of calculating an impact factor. For this reason, Jurnal Ilman: Jurnal Ilmu Manajemen applies Thomson Reuters'(TR) algorithm as published on http://wokinfo.com/essays/impact-factor in Figure 1. This algorithm is not protected and can be used by anyone. In short: Journal of Midwifery calculates a 2-year Google-based Journal Impact Factor (2-GJIF).
With respect to all articles from this journal for the respective year:
A = total cites in 2019 = 43
B = 2018 cites to articles published in 2014 – 2018 = 60 (this is a subset of A)
C = number of articles published in 2016-17 = 103
2-GJIF for 2018 = C = A/B = 184/373 = 0.716 (TR algorithm, Google citations, data December 2019)
Journal self-citations are citations to articles in the same journal. A Self-Cited Rate below 20 % is considered acceptable. A higher Self-Cited Rate than this could be explained by a journal’s novel or highly specific topic, but could also reveal a journal with excessive self-citations.
Please interpret the 2-GJIF with caution:
- Due to differences in the underlying database, the value calculated here for the 2-GJIF cannot be compared with a JCR®2-JIF.
- Do not compare journals from different subject fields based on their JIF. Journals in fundamental subject fields tend to have higher impact factors than journals in specialized or applied subject fields.
- Journal metrics should not be used to assess individual authors. Please refer instead to our article metrics provided for each paper: Number of citations from Google Scholar and a number of citations from CrossRef.
