Technological change in the production of new scientific knowledge: a second look

This paper presents and explains an approach for measuring technological change in the production of new scientific knowledge. The paper expands our previous work on this topic. Our approach is illustrated by using as an example new scientific journal publications from the U.S. National Institute of Standards and Technology. The empirical findings are consistent with the expectation that resource constraints will cause a breakdown in the process of creating new scientific knowledge and with the evidence that scientific research has been less productive in recent decades.
