Scoring 50 years of US industrial policy, 1970–2021

Successful outcome = A The startup subsidy of $250 million, averaged over 10 years of Mercedes employment, works out to about $16,700 per job-year, well below our threshold of the state average annual wage in 2021, $54,000. By this criterion, many state industrial policy initiatives are successful at creating jobs.

7. Directional Drilling and Tunneling

Tunneling and drilling operations fall into two broad categories: (1) operations in which excavation is carried out by attacking the rock face selectively, and (2) operations that use a device to advance the whole cross section of the excavation simultaneously. The first

The Liuqu Conglomerate, southern Tibet: Early Miocene basin development related to deformation within

In this study, we present an in-depth analysis of the age, depositional environment, provenance, and causes of basin formation for the Liuqu Conglomerate. The age of the Liuqu Conglomerate is refined through 40 Ar/ 39 Ar dating of a crosscutting dike, detrital zircon U-Pb and zircon fission-track dating, reanalysis of published pollen data, and carbon stable isotope analyses of soil carbonates.
