JSER Scopus metrics for 2014

Dear colleagues and readers,
JSER has new Scopus metrics for 2014. SNIP 2014  = 0.115; IPP 2014 = 0.14; SJR 2014 = 0.109.
SNIP is Source Normalized Impact per Paper measures contextual citation impact by weighting citations based on the total number of citations in a subject field. As a field-normalized metric SNIP offers researchers, authors, and librarians the ability to benchmark and compare journals from different subject areas. This is especially helpful to researchers publishing in multidisciplinary fields.
SJR is SCImago Journal Rank is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation. It is a size-independent indicator and it ranks journals by their 'average prestige per article' and can be used for journal comparisons in the scientific evaluation process.
IPP is The Impact per Publication measures the ratio of citations per article published in the journal.
The Impact per Publication measures the ratio of citations in a year (Y) to scholarly papers published in the three previous years (Y-1, Y-2, Y-3) divided by the number of scholarly papers published in those same years (Y-1, Y-2, Y-3).
The Impact per Publication metric is using a citation window of three years which is considered to be the optimal time period to accurately measure citations in most subject fields.
Taking into account the same peer-reviewed scholarly papers only in both the numerator and denominator of the equation provides a fair impact measurement of the journal and diminishes the chance of manipulation.
