551 Roger Wolcott Richardson was born on 30␣ May 1930 in Baton Rouge, Louisiana. He was the eldest of the four sons of Roger Wolcott Richardson jr and Cora Johnson. His father was completing a Ph.D. in chemical engineering at the time of Richardson’s birth and subsequently devoted virtually his whole working life to a career as an executive with Standard Oil (later the Exxon Corporation). His y...

We investigate the role of industrial structure in labor productivity growth in U.S. cities between 1880 and 1930 using a new dataset constructed from the Census of Manufactures. We find that increases in specialization were associated with faster productivity growth but that diversity only had positive effects on productivity performance in large cities. We interpret our results as providing s...

IN previous communications the electrode potential behaviour of haemolytic streptococci [Hewitt, 1930, 1], C. diphtheriae [1930, 2], staphylococci [1930, 3] and pneumococci [1930, 4] has been described by the author and it has been shown that the oxidation-reduction potentials established in bacterial cultures depend upon the cultural conditions and upon the organism studied. The potentials dev...

Swine influenza was first recognized as a disease entity during the 1918 "Spanish flu" pandemic. The aim of this work was to determine the virulence of a plasmid-derived human 1918 pandemic H1N1 influenza virus (reconstructed 1918, or 1918/rec, virus) in swine using a plasmid-derived A/swine/Iowa/15/1930 H1N1 virus (1930/rec virus), representing the first isolated influenza virus, as a referenc...

aseptic meningitis or benign lymphocytic meningitis has been given. Wallgren (1925) gave the first account of this condition. His observa, tions were based on a small epidemic. Since then it has been described from time to time by many physicians under different names ?aseptic benign purulent meningitis (Schiff, 1930), idiopathic benign serous, meningitis (Andersen and Wulff, 1930), epidemic me...

Inter-generation differences in foot dimensions were examined using ANCOVA to determine whether aging or secular change is the more important causal factor. In examining the results, bone size was assumed not to change after the end of linear growth, while foot arches were assumed to become flatter rather than higher if there were any changes in skeletal structure. Changes in overall body build...

We investigate the expectations hypotheses of the term structure of interest rates and of the foreign exchange market using vector autoregressive methods for U.S. dollar, Deutsche mark, and British pound interest rates and exchange rates. We examine Wald, Lagrange multiplier, and distance metric tests by iterating on approximate solutions that require only matrix inversions. Bias-corrected, con...
