The New York Times for the second time this week has an article about declining numbers of science PhDs.
The impetus this time is a new report by the National Science Board. From the NYT article:
"For many years we have benefited from minimal competition in the global science and engineering labor market," he said. "But attractive and competitive alternatives are now expanding around the world."
The press release from the National Science Board states that "U.S.-based authors continue to produce the largest share of scientific journal articles, but U.S. article output has flattened since 1992, a trend that has not been observed in other developed countries. The National Science Foundation (NSF) is engaged in an in-depth study of worldwide trends in article production and how and why they may be changing (Chapter 5)."
