Three major sources of financial support for the research undertaken by Edwards, Steptoe and Purdy between 1969 and 1978 are identified: the Ford Foundation, Oldham and District General Hospital (ODGH) Management Committee, and Miss Lillian Lincoln Howell via the American Friends of Cambridge University. Significant possible financial support from the World Health Organization was also identifi...

In this study, I re-analyze data from a meta-analysis of research on the job characteristics model (Hackman & Oldham, 1980), using relative weights analysis (Johnson, 2001). This analytic technique is particularly well-suited for analyses in which one wants to most accurately determine the proportion of explained variance in a dependent variable among several independent variables, while avoidi...

We review the localization formula due to Berline-Vergne and Atiyah-Bott, with applications to the exact stationary phase phenomenon discovered by Duistermaat-Heckman. We explain the Weil model of equivariant cohomology and recall its relation to BRST. We show how to quantize the Weil model, and obtain new localization formulas which, in particular, apply to Hamiltonian spaces with group valued...

Human capital production in the U.S. economy is no longer what it used to be. Graduation rates for high school and college have fallen (Card and Lemieux 2001; Heckman and Lafontaine 2007). As a result, the rate of growth of the stock of human capital has slowed considerably (Goldin and Katz 2008). At the same time, other countries are improving their educational attainment. Although the United ...
