- The state average of this indicator declined between 1993 and 2001.
- During this period, the number of scientific and technical articles remained
fairly constant at 140,000–150,000, whereas the number of S&E doctorate
holders employed in academia rose from 210,000 to 245,000.
- The indicator values of many states were volatile between 1993 and 2001.
- In 2001, the states with the highest values for this indicator were spread
across the nation.
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 the Institute for Scientific Information's Science Citation
Index and Social Sciences Citation Index. The number of journals was 4,601 in
1993, 5,029 in 1997, and 5,262 in 2001. 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.
