We provide a new examination of the incentive effects of welfare rules on family structure among low-income women by emphasizing that the eligibility and benefit rules in the AFDC and TANF programs are based more on the biological relationship between the children and any male in the household than on marriage or cohabitation per se. Using data from 1996 through 2008, we analyze the effects of ...

The lipocalin protein family is a large group of small extracellular proteins. The family demonstrates great diversity at the sequence level; however, most lipocalins share three characteristic conserved sequence motifs, the kernel lipocalins, while a group of more divergent family members, the outlier lipocalins, share only one. Belying this sequence dissimilarity, lipocalin crystal structures...

This paper examines the relationship between family structure and child poverty in Canada over the 1981-1997 period. While recognising the many methodological and conceptual difficulties encountered in efforts to document child poverty over time, two alternate indicators are used, Statistics Canada’s official low income cut-offs, and an alternate indicator of "deep poverty”. Using the Survey of...

Mo K-edge X-ray absorption spectroscopy has been used to probe as-isolated structures of the MOSC family proteins pmARC-1 and HMCS-CT. The Mo K-edge near-edge spectrum of HMCS-CT is shifted ~2.5 eV to lower energy compared to the pmARC-1 spectrum, which indicates that as-isolated HMCS-CT is in a more reduced state than pmARC-1. Extended X-ray absorption fine structure analysis indicates signifi...

The 1972 survey of the disabled and nondisabled provides comparative data on the two groups that can be used to assess the effects of disability on the family structure. Although the disabled were about as likely to have married as persons in the general population, the stability of their marriages was more limited. The extended families of disabled persons generally provided no greater support...

I use a new data source, the Integrated Public Use Microdata Series, to trace race differences in family structure between 1880 and 1980. Analysis confirms recent findings that the high incidence among African-Americans of single parenthood and children residing without their parents is not a recent phenomenon. From 1880 through 1960, black children were two to three times more likely to reside...

The Cation Diffusion Facilitators (CDFs) form a family of membrane-bound proteins capable of transporting zinc and other heavy metal ions. Involved in metal tolerance/resistance by efflux of ions, CDF proteins share a two-modular architecture consisting of a transmembrane domain (TMD) and C-terminal domain (CTD) that protrudes into the cytoplasm. Discovery of a Zn²⁺ and Cd²⁺ CDF transporter fro...

The article explores a series of questions and hypotheses related to polygynous family structures and both household and individual-level food security outcomes, using the World Bank Living Standards Measurement Survey data from Nigeria, collected in 2011, 2013 and 2015. A Correlated Random Effects (CRE) model is used to examine the relationship between polygyny and household-level food securit...
