Resolving both crustal and shallow-mantle heterogeneity, which is needed to study processes in and fluxes between crust and mantle, is still a challenge for seismic tomography. Body wave data can constrain deep features but often produce vertical smearing in the crust and upper mantle; in contrast, surface wave data can provide good vertical resolution of lithospheric structure but may lack lateral resolution and are less sensitive to the deeper Earth. These two data types are usually treated and inverted separately, and tomographic models therefore do not, in general, benefit from the complementary nature of sampling by body and surface waves. …

While the role of immigration and neighborhood change has been studied since the days of the Chicago School of Sociology, recent restrictions to immigration in concert with state and local initiatives to both enforce immigration policy or welcome immigrants raises new questions about neighborhood sorting within metropolitan areas. Policy makers are interested in recruiting high skilled and wealthy immigrants to attract investment and create jobs for native-born citizens. Some have endorsed welcoming immigrants as a solution to regional economic development and to stabilize high poverty urban neighborhoods. Are these immigrant recruitment policies realistic given existing patterns of immigrant housing location …
