Findings
- Between 1997 and 2003, the number of scientific and technical articles increased by 8%, and the number of S&E doctorate holders increased by the same percentage, causing the value of this indicator to remain almost unchanged for the United States.
- The publication rate for academic S&E doctorate holders in states in the top quartile of this indicator was approximately twice as high as for states in the bottom quartile.
- States with the greatest volatility on this indicator frequently had larger changes in academic employment than in number of publications.
- In 2003, the states with the highest values for this indicator were distributed across the nation.
Description
The volume of peer-reviewed articles per 1,000 academic science and engineering doctorate holders is an approximate measure of their contribution to scientific knowledge. Publications are only one measure of academic productivity, which includes trained personnel, patents, and other outputs. A high value on this indicator shows that the S&E faculty in a state’s academic institutions are generating a high volume of publications relative to other states.
Publication counts are based on the number of articles appearing in a set of journals listed in Thomson ISI’s Science Citation Index and Social Science Citation Index. The number of journals in this set was 5,029 in 1997, 5,255 in 2001, and 5,315 in 2003. Articles with authors in different institutions were counted fractionally. For a publication with N authors, each author’s institution was credited with 1/N articles.
S&E doctorates include physical, life, earth, ocean, atmospheric, computer, and social sciences; mathematics; engineering; and psychology. Medical doctorates and S&E doctorates from foreign institutions are excluded.
