This study uses the unique design of the Gautreaux residential mobility program to estimate the long-run impacts of placement neighborhood conditions on the AFDC receipt (N = 793) and employment levels (N = 1258) of low-income Black women. We find that women initially placed in neighborhoods with few Black residents and moderate to high neighborhood resources experienced significantly more time...

With the development of high-throughput methods for identifying protein-protein interactions, large scale interaction networks are available. Computational methods to analyze the networks to detect functional modules as protein complexes are becoming more important. However, most of the existing methods only make use of the protein-protein interaction networks without considering the structural...

SSO2064 is the first structural representative of PF01796 (DUF35), a large prokaryotic family with a wide phylogenetic distribution. The structure reveals a novel two-domain architecture comprising an N-terminal, rubredoxin-like, zinc ribbon and a C-terminal, oligonucleotide/oligosaccharide-binding (OB) fold domain. Additional N-terminal helical segments may be involved in protein-protein inter...

Despite the attention that the fertility of welfare recipients has received recently, surprisingly little is known about it. This paper answers some basic questions about the phenomenon of welfare births. Among the findings from the March 1987 Current Population Survey are that 13.4 percent of all births are into the 7.3 percent of families receiving Aid to Families with Dependent Children (AFD...

The Correlates of Work in a Post-AFDC World: The Results from a Longitudinal State-Level Analysis Much of the research that has followed welfare reform and new policies such as the Temporary Assistance for Needy Families (TANF) has focused on identifying the variations in how different states have put the new policy into practice. Less is known however, about how this new policy affects the abi...

This study uses the National Longitudinal Survey of Youth, supplemented with state data on welfare policy, to provide new evidence on the link between welfare and teenage out-of-wedlock childbearing in the 1979-1984 period. Logit cross-section and discrete-time hazard models are estimated separately for Hispanics, blacks and whites. The key finding is that, in contrast to the results shown in o...

PROCOGNATE is a database of protein cognate ligands for the domains in enzyme structures as described by CATH, SCOP and Pfam, and is available as an interactive website or a flat file. This article gives an overview of the database and its generation and presents a new website front end, as well as recent increased coverage in our dataset via inclusion of Pfam domains. We also describe navigati...

The paper analyzes the effect of economic incentives in the AFDC program on the employment of AFDC mothers. Multiple regression analysis is applied to cross-sectional aggregate state program data for 1967. Our estimates indicate that the level of guarantees, tax rates and set-asides affect AFDC employment rates in the direction predicted by economic theory. Short of a drastic reduction in guara...

This paper considers the effect of child care costs on two labor market decisions of single mothers--whether to participate in the labor market and whether to receive AFDC. Weekly child care expenditures are estimated for all women in the sample (taken from the 1984 Panel of SIPP), whether or not they are currently using nonmaternal child care. These expenditures are then included as an indepen...
