Scope/Description:

•From the start, the journal was a truly international research journal accepting qualified original articles written in Japanese, English, German, French, or Italian from throughout the world. The financial burden on Professor Hayashi must have been considerable. President Masataro SAWAYANAGI of the Tohoku Imperial University tried to alleviate this burden by arranging for the university to purchase copies which were then donated to other universities and learned societies throughout the world. On the advice of the Board of Audit of the Japanese Government, the management of the journal was transferred to the university, although Professor Hayashi continued to serve as Chief-Editor until the end of his life.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?


III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

H-Index

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
