an impact factor of more than 1 is a very powerful concept.
if you are the first author, then 1 points is awesome, and the work is very powerful. meta and review are retrospective studies, so they are not innovative. The magazine partition of Chinese Academy of Sciences is very stable. In some fields, the influence factor of TOP magazine is still only a few points.
in the signature of innovative works, such as scientific research papers, patents, research reports, etc., the name of the person who has made the greatest contribution to the work is usually signed at the front. Especially for the signature of scientific research papers, each journal has more detailed regulations; However, when the signature of the paper is used for the evaluation of professional titles, the weight of the first author is obviously heavier than that of the second and third authors, but lighter than that of the individual signature.
significance
impact factors are not the most objective criteria for evaluating the influence of journals. Generally speaking, the higher the impact factor, the greater the influence of the journal. For some comprehensive or major research fields, the citation rate is relatively high because of the wide range of research fields. For example, biological and chemical journals are generally more likely to have higher influence.
although the impact factor can characterize the academic quality to a certain extent, there is no linear proportional relationship between the impact factor and the academic quality. For example, it cannot be said that a journal with an impact factor of 5. is definitely better than a journal with an impact factor of 2., and the impact factor does not have the function of accurately and quantitatively evaluating the academic quality.
