Input name | Variable name | Explanation | |
|---|---|---|---|
1 | Age | age | The age of the survey subject |
2 | Sex | sex | The sex of the survey subject |
3 | Affiliation | affil | During the manual phase, we chose the affiliations where the researchers are full-time employed. During the semi-automatic phase, due to the data structure, we assigned the affiliations according to each paper. |
4 | Region | reg | A region is specified by the affiliations of the researchers. There are four categories: North, South, Centre and Overseas. |
5 | Fields of study | field | During the manual phase, we chose the field registered as their major in PhD or Master degree. During the semi-automatic phase, due to the data structure, we assigned the fields of study according to each paper. |
6 | Total items | ttitems | The total number of publications in Scopus. Unit: item(s). |
7 | Solo author | au.solo | The number of solo publications. Unit: item(s). |
8 | Key author | au.key | The number of publications the survey subject is in leading role. A person is considered to have a leading role in an article when he or she served as the solo author, the first author or the corresponding author. Unit: item(s). |
9 | Co-author | au.co | The number of publications where the survey subject is neither leading author nor solo author. Thus, au.co=ttlitems−au.key. Unit: item(s). |
10 | Contribution-adjusted productivity | cp: cp.sdc, cp.eq, cp.fl | The measure of relative scientific output. When we calculate this measure manually, the absolute productivity is converted using the method of sequence-determines-credit (cp.sdc)29–31. Then, using the semi-automatic system, we added two more measures: equal contribution for all (cp.eq) and first-last-author emphasis (cp.fl)29,31. |
11 | Vietnamese author | au.vn | The number of Vietnamese researchers a survey subject has co-authored with. Each Vietnamese researcher is counted only once. Unit: people. |
