A closer look at the Impact Factor (JCR 2012): problems, concerns and actions needed

Egg accumulation with 3D embryos provides insight into the life history of a pterosaur

“…espite recent progress, the general paucity of pterosaur bonebeds confidently composed of a single species hampers our understanding of several biological questions (1,2), including their ontogenetic development and reproductive strategy. Only a handful of isolated occurrences of eggs and embryos have been reported so far (2)(3)(4)(5)(6).…”

Brief comments on the 2020 Impact Factor of the AABC released by Journal Citation Reports

“…If one would like to get an idea of the impact of articles, more than the journal itself where they are published, the best source is not the JCR database, in which the exclusion of articles happens with apparent frequency and seems to be random -you might never know who is the lucky one. Missing articles are only discovered post factum and regardless of what is done, corrections to citations and IF are infrequent (e.g., Kellner & Azevedo 2013, Kellner 2020c). The database presented by WoS, while also susceptible to miss articles (Kellner 2020b), has at least been corrected and papers (apparently also citations) can be (re)included.…”

“…This is the second consecutive year that papers published by the AABC get missing and were not made available for the JCR calculation. This situation has occurred previously (Kellner & Azevedo 2013), suggesting that missing articles (evaluated by MAI) happens with some frequency and perhaps should be studied in other periodicals to get a sense of how this loss influences journal (and possible author) indexes.…”

Development of Agrarian Sciences at the AABC with comments on impact and performance evaluations

“…Together with Scientific Electronic Library Online (SciELO) we are trying to fix this situation so authors will not be harmed in their publication metrics. It should be noted that the AABC had faced this problem in the past, which was only partially solved: the papers of a missing issue (AABC-84.2) were included but the IF was not recalculated, bringing a loss to the indicators of the journal, that was not to blame for the omission (Kellner & Azevedo 2013). MAI of AABC-84.2 is 1 (the maximum and most damaging that could be achieved) and is also considerable high for the year 2012: 0.2308.…”
