Published papers

Scholarly journals are considered as media for disseminating research results. To clarify the characteristics of Japanese scholarly journals, the analysis of journals in physics, Japanese literature and political science (300 journals in total) are examined from the point such as original papers contained, the numbers of original papers published in a year, the types of editorial organization, referee systems and types of articles included in the journal. Main findings are as follows: (1) In physics, 3 famaous learened journals in english formed the core. A large number of journals consist of only original papers. (2) In the field of Japanese literature, college bulletins and commercial journals devoted to Japanese literature formed the core. (3) In political science, there are almost not journals devoted to political science. The most of journals consist of variety articles.

As an approach to researching the process of producing academic information, this paper focuses on scholars who are producers of academic information, and examines various factors which determine scientists' publication productivity. Various factors found in previous research can be classified into three types; six factors are then selected from these three types: age, prestige of graduate school, kind of degree, institutional affiliation, position at the institution and "the mean number of authors per article". About 100 Japanese physical scientists, their main publication records and these six factors are then examined. The findings are as follows: (1) For each factor, groups who have a high level of productivity are scientists who; a) are in their forties, b) graduated from seven major national universities, c) hold a doctorate in engineering, d) belong to seven major national universities or national laboratories, e) are professors or assistants and f) have a "mean number of authors" of eight. (2) As a result of the Quantification theory I with six factors, it was found that the multiple correlation coefficient is 0.63, and that "mean number of authors" has the most influence on publication productivity.

As an approach to researching the process of producing information, this paper focuses on scholars who are producers of academic information, and examines various factors of scholarly productivity. Among the many factors of productivity, three are selected; the university to which a scholar belongs, the prestige of the graduate schools and media through a scholar publishes the results of his/her research (in this paper, "media" means the journals which carry scholarly articles, and the publishers which publish scholary books). About 828 Japanese political scientists, their publication main records and several factors are examined. The findings are as follows; (1) Almost all Japanese political scientists who belong to distinguished universities (Tokyo University, the four major national universities, and the two major private universities), graduated from these universities. But only one-forth of scholars, who graduated from distinguished universities belong to these universities. (2) All scholars who belong to or graduated from distinguished universities don't necessarily have a high level of productivity. (3) About 90 per cent of the books written by these scholars, are published through general commercial publishers, followed by university bulletins and general commercial journals. (4) In book media, the scholars who graduated from the two major private universities publish about 25 per cent of their works through university presses. In academic journal media, only the scholars who graduated from Tokyo University publish large proportion of their articles through general commercial journal.
