首先,用橙色背景突出显示了“Supports Open Access”;此外,“Journal Metrics”中除了我们熟知的Impact Factor、5-Year Impact Factor之外,新添加了三个指标Source Normalized Impact per Paper (SNIP)、Impact per Publication (IPP)、SCImago Journal Rank (SJR)。
Source Normalized Impact per Paper (SNIP): 2013: 2.361 SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
Impact per Publication (IPP): 2013: 4.032 The Impact per Publication measures the average number of citations received in a particular year by papers published in the journal during the three preceding years.
SCImago Journal Rank (SJR): 2013: 2.812 SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
Impact Factor: 2012: 3.406 The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.
Five-Year Impact Factor: 2012: 3.746 To calculate the five year Impact Factor, citations are counted in 2012 to the previous five years and divided by the source items published in the previous five years.
This short note concerns the cavalier attitude that seems to be prevalent now with regard to checking the accuracy of the references that are provided in research publications. Daunting difficulties confront, at times, those trying to check a source, especially when the source is several centuries old and/or in a language that the researcher is not conversant with. Compounding the problem further, at times, are insuperable difficulties with regard to deciding whom or what to accept as proper authority in the attribution of citations, nudging those that are not of sterner stuff to take the easy way out and conform to popular opinion that might be incorrect. In this short note I discuss the difficulties that a researcher might face with regard to proper attribution of ideas.
