Family Structure and the Economic Wellbeing of Children

An extensive literature that examines the relationship between family structure and children's outcomes consistently shows that living with a single parent is associated with negative outcomes. Few studies, however, directly test the relationship between family structure and outcomes for the child once he/she reaches adulthood. We directly examine, using the Panel Study of Income Dynamics, whether family structure during childhood is related to the child's economic wellbeing both during childhood as well as adulthood. Our findings suggest that the economic wellbeing of children of mothers who experience a marital dissolution and remarry are no different from the children of mothers who are continuously married. However, the children of mothers whose marriages dissolve but who do not remarry experience large declines in their income over their first ten years of life. We also show that while the children of never married mothers earn a lot less as adults than the children of married parents, these differences can largely be explained by demographic and socioeconomic factors. Finally, our findings suggest that children who have mothers who experience a marital dissolution and who do not remarry have economic losses that persist into adulthood.

Family Structure and the Economic Mobility of Children

Compares the economic mobility, both absolute and relative, of children of continuously married mothers, divorced mothers, and unmarried mothers by race and family income level. Explores the role of racial differences in family structure and implications

A stochastic model for wound healing

We present a discrete stochastic model which represents many of the salient features of the biological process of wound healing. The model describes fronts of cells invading a wound. We have numerical results in one and two dimensions. In one dimension we can give analytic results for the front speed as a power series expansion in a parameter, p, that gives the relative size of proliferation and diffusion processes for the invading cells. In two dimensions the model becomes the Eden model for p near 1. In both one and two dimensions for small p, front propagation for this model should approach that of the Fisher-Kolmogorov equation. However, as in other cases, this discrete model approaches Fisher-Kolmogorov behavior slowly.Comment: 16 pages, 7 figure

Medicaid Expansions and Fertility in the United States

Beginning in the mid 1980s and extending through the early to mid 1990s, a substantial number of women and children gained eligibility for Medicaid through a series of income-based expansions. Using natality data from the National Center for Health Statistics, we estimate fertility responses to these eligibility expansions. We measure changes in state Medicaid eligibility policy by simulating the fraction of a standard population that would qualify for benefits. From 1985 to 1996, the fraction of women aged 15 to 44 who were eligible for Medicaid coverage for a pregnancy increased on average by 24 percentage points. However, contrary to findings in the extant literature, our results do not indicate that this expansion in coverage had a statistically discernible effect on fertility.

The Everyday First Amendment

On June 26 and June 27, 2019, some twenty contenders for the Democratic nomination for President of the United States participated in two evenings of political debate. The outsized group included Rep. Tulsi Gabbard of Hawaii, who was struggling to gain traction with voters. Shortly after the debate, while many viewers were conducting online searches to learn more about the candidates, Google temporarily suspended her campaign’s advertising account. Google claimed that the interruption occurred because an automated system flagged unusual activity on the account. But Gabbard did not accept this explanation; she believed that Google deliberately had tried to undermine her campaign in retaliation for statements she had made that were critical of the tech giant. As a result, in July of 2019 her presidential campaign organization sued Google, alleging that the company had violated her First Amendment rights. The lawsuit sought $50 million in damages

Subunit-Selective Interrogation of CO Recombination in Carbonmonoxy Hemoglobin by Isotope-Edited Time-Resolved Resonance Raman Spectroscopy

Hemoglobin (Hb) is an allosteric tetrameric protein made up of αβ heterodimers. The α and β chains are similar, but are chemically and structurally distinct. To investigate dynamical differences between the chains, we have prepared tetramers in which the chains are isotopically distinguishable, via reconstitution with 15N-heme. Ligand recombination and heme structural evolution, following HbCO dissociation, was monitored with chain selectivity by resonance Raman (RR) spectroscopy. For α but not for β chains, the frequency of the ν4 porphyrin breathing mode increased on the microsecond time scale. This increase is a manifestation of proximal tension in the Hb T-state, and its time course is parallel to the formation of T contacts, as determined previously by UVRR spectroscopy. Despite the localization of proximal constraint in the α chains, geminate recombination was found to be equally probable in the two chains, with yields of 39 ± 2%. We discuss the possibility that this equivalence is coincidental, in the sense that it arises from the evolutionary pressure for cooperativity, or that it reflects mechanical coupling across the αβ interface, evidence for which has emerged from UVRR studies of site mutants
