The empirical relationship between economic diversity and economic stability varies when it is measured at different geographical scales. This paper evaluates the role of geographical scales in assessing this diversity-stability relationship among counties, states, Economic Areas (EAs), metropolitan counties and metropolitan statistical areas (MSAs) in the contiguous U.S. When choosing geograph...

Abstract Although (Soddy, Nature 92:399–400, 1913) inferred the existence of isotopes early last century, it was not until discovery neutron by (Chadwick, 129:312, 1932) that were understood to result from differing numbers neutrons in atomic nuclei. (Urey, J Chem Soc 1947:562–581, 1947) predicted different would behave slightly differently chemical (and physical) reactions due mass differences...
