Net Operating Working Capital Behavior: A First Look

Abstract: Net operating working capital captures multiple dimensions of firms’ adjustments to operating and financial conditions. Sales growth, uncertainty of sales, costly external financing, and financial distress encourage firms to pursue more aggressive working capital strategies. Firms with greater internal financing capacity and superior capital market access employ more conservative working capital policies. Results are robust to unobserved heterogeneity and industry effects. The evidence suggests that operating and financing conditions should be considered when evaluating working capital behavior, not just industry averages. Additionally, industry concentration magnifies the effect of sales growth.

Glucan administration potentiates immune defence mechanisms of channel catfish, Ictalurus punctatus Rafinesque

Abstract: . Intraperitoncal injection of β-l,3 glucan in channel catfish, Ictalurus punctatus Rafinesque, greatly reduces mortality from experimental infection with Edwardsiella ictaluri. Anterior kidney phagocytes from fish receiving glucan had enhanced phagocytic and bactericidal ability. The elevated bactericidal ability of phagocytes was not accompanied by increased production of hydrogen peroxide. Fish injected with glucan responded to subsequent E. ictaluri immunizations with higher serum antibody titres relative to the control catfish. The timing of glucan administration and antigen immunization was also important. These results indicate that β-1,3 glucan potentially could be utilized prophylactically as an immunomodulator in channel catfish.

The Geography of Exclusion: Race, Segregation, and Concentrated Poverty

Abstract: The late 2000s Great Recession brought rising neighborhood poverty in the midst of affluence, and the reemergence of a racial and ethnic “underclass” living in inner-city neighborhoods. Our approach redirects attention to a level of geography–cities, suburbs, and small rural towns–where local political and economic decisions effectively exclude the poor and minority populations. It uses newly released poverty data from the 2005–2009 American Community Survey to provide evidence of changing macro patterns of spatially concentrated poverty. We show that roughly one in four U.S. places had poverty rates exceeding 20 percent in 2005 through 2009, up 31 percent since 2000. Roughly 30 percent of America's poor reside in poor places, and concentrated poverty is especially high among poor African Americans. Overall increases in place-based poverty nonetheless were muted over the decade by declines in concentrated poverty among poor Hispanics (a pattern that reflects spatial diffusion to new destinations). We also show that America's poor were sorted unevenly from place-to-place within local labor markets (i.e., counties); poor-nonpoor segregation rates between places increased from 12.6 to 18.4 between 1990 and the 2005–2009 period. Segregation was especially high among disadvantaged blacks and Hispanics. Our empirical results make a case for more scholarly attention on newly emerging patterns of concentrated poverty at the place level.
