WIC in Your Neighborhood: New Evidence on the Impacts of Geographic Access to Clinics

A large body of evidence indicates that conditions in-utero and health at birth are predictive of individuals' long-run outcomes, pointing to the potential value in programs aimed at pregnant women and new mothers. This paper uses a novel identification strategy and data set to provide causal estimates of the effects of geographic access to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), the major US program aimed at improving the well-being of low-income pregnant and post-partum women, infants, and children under age 5. I utilize data on sibling births over 2005-2009 and administrative records on the locations and dates of openings and closings of WIC clinics over the same time period. The empirical approach uses within-zip-code variation in WIC clinic presence together with maternal fixed effects, and accounts for the potential endogeneity of mobility, gestational-age bias, and measurement error in gestation. The results show that geographic access to WIC clinics increases the likelihood of WIC food benefit take-up, and decreases the likelihood of gaining too little weight during pregnancy. I also provide some evidence that other aspects of the WIC program, such as health screenings and referrals to other services may have effects on women's behaviors during pregnancy. Finally, I show that access to WIC increases average birth weight and the likelihood of breastfeeding at the time of hospital discharge. The effects are strongest for mothers with a high school education or less, who are most likely eligible for WIC services

Assessing Rhode Island’s Temporary Caregiver Insurance Act: Insights from a Survey of Employers

This report provides new evidence on Rhode Island’s Temporary Caregiver Insurance (TCI) law, which took effect in January 2014, based on a survey of small and medium-sized businesses in the food services and manufacturing sectors in Rhode Island, Connecticut, and Massachusetts that we carried out in December 2013 (just before the law came into effect) and in January/February 2015 (one year after the law came into effect). We collected information about firm characteristics and productivity, employee life events and work flow, and employer-provided benefits. Comparing Rhode Island employers pre-and post-law to Massachusetts and Connecticut employers over the same time period, we found little evidence of significant impacts of the law on employers (although we note that the sample size for these estimates was small; 104 employers in Rhode Island, and 133 in the other two states combined). We also asked Rhode Island employers directly about their views towards TCI one year after it came into effect and found that a majority of the 213 Rhode Island employers interviewed in 2015 support the new law. Thus, our results suggest that laws like Rhode Island’s TCI may not have significant impacts on small and medium-sized employers and could garner support by such employers once they have experienced them

The Effects of California’s Paid Family Leave Program on Mothers’ Leave-Taking and Subsequent Labor Market Outcomes

This analysis uses March Current Population Survey data from 1999-2010 and a differences-in-differences approach to examine how California’s first in the nation paid family leave (PFL) program affected leave-taking by mothers following childbirth, as well as subsequent labor market outcomes. We obtain robust evidence that the California program more than doubled the overall use of maternity leave, increasing it from around three to six or seven weeks for the typical new mother – with particularly large growth for less advantaged groups. We also provide suggestive evidence that PFL increased the usual weekly work hours of employed mothers of one-to-three year-old children by 6 to 9% and that their wage incomes may have risen by a similar amount.

The effects of maternity leave on children's birth and infant health outcomes in the United States

This paper evaluates the impacts of unpaid maternity leave provisions of the 1993 Family and Medical Leave Act (FMLA) on children's birth and infant health outcomes in the United States. My identification strategy uses variation in pre-FMLA maternity leave policies across states and variation in which firms are covered by FMLA provisions. Using Vital Statistics data and difference-in-difference-in-difference methodology, I find that maternity leave led to small increases in birth weight, decreases in the likelihood of a premature birth, and substantial decreases in infant mortality for children of college-educated and married mothers, who were most able to take advantage of unpaid leave. My results are robust to the inclusion of numerous controls for maternal, child, and county characteristics, state and year fixed effects, and state-year interactions, as well as across several different specifications

Trends and Disparities in Leave Use Under California\u27s Paid Family Leave Program: New Evidence from Administrative Data

We use novel administrative data to study trends and disparities in usage of California\u27s first-in-the-nation paid family leave (PFL) program. We show that take-up for both bonding with a new child and caring for an ill family member increased over 2005–2014. Most women combine PFL with maternity leave from the State Disability Insurance system, resulting in leaves longer than 6 weeks. Most men take less than the full 6 weeks of PFL. Individuals in the lowest earnings quartile and in small firms are the least likely to take leave. There are important differences in take-up across industries, especially for men

The impacts of paid family and medical leave on worker health, family well-being, and employer outcomes

This article reviews the evidence on the impacts of paid family and medical leave (PFML) policies on workers' health, family well-being, and employer outcomes. While an extensive body of research demonstrates the mostly beneficial effects of PFML taken by new parents on infant, child, and parental health, less is known about its impact on employees who need leave to care for older children, adult family members, or elderly relatives. The evidence on employers is similarly limited but indicates that PFML does not impose major burdens on them. Taken together, the evidence suggests that PFML policies are likely to have important short- and long-term benefits for population health, without generating large costs for employers. At thesame time, further research is needed to understand the effects of different policy parameters (e.g., wage replacement rate and leave duration) and of other types of leave beyond parental leave

Data and evidence about sex worker communities are often collected by outsiders, and the ownership of data is rarely with sex workers themselves. In order to challenge this dynamic, Tactical Tech developed the idea of producing an 'Atlas of Sex Work.' The Women’s Network for Unity report on sex worker abuse is included

Evaluating the impact of programmatic mass drug administration for malaria in Zambia using routine incidence data.

BACKGROUND NlmCategory: BACKGROUND content: In 2016, the Zambian National Malaria Elimination Centre started programmatic mass drug administration (pMDA) campaigns with dihydroartemisinin-piperaquine as a malaria elimination tool in Southern Province. Two rounds were administered, two months apart (coverage 70% and 57% respectively). We evaluated the impact of one year of pMDA on malaria incidence using routine data. - Label: METHODS NlmCategory: METHODS content: We conducted an interrupted time series with comparison group analysis on monthly incidence data collected at the health facility catchment area (HFCA) level, with a negative binomial model using generalized estimating equations. pMDA was conducted in HFCAs with greater than 50 cases/1,000 people/year. Ten HFCAs with incidence rates marginally above this threshold (pMDA group) were compared to 20 HFCAs marginally below (comparison group). - Label: RESULTS NlmCategory: RESULTS content: "The pMDA HFCAs saw a 46% greater decrease in incidence at the time of intervention than the comparison areas (incidence rate ratio: 0.536 [0.337-0.852]); however, incidence increased toward the end of the season. No HFCAs saw a transmission interruption." - Label: CONCLUSION NlmCategory: CONCLUSIONS content: pMDA, implemented during one year with imperfect coverage in low transmission areas with sub-optimal vector control coverage, significantly reduced incidence. However, elimination will require additional tools. Routine data are important resources for programmatic impact evaluations and should be considered for future analyses

Structure and evolution of the gorilla and orangutan growth hormone loci

In primates, the unigenic growth hormone (GH) locus of prosimians, expressed primarily in the anterior pituitary, evolved by gene duplications, independently in New World Monkeys (NWM) and Old World Monkeys (OWMs)/apes, to give complex clusters of genes expressed in the pituitary and placenta. In human and chimpanzee, the GH locus comprises five genes, GH-N being expressed as pituitary GH, whereas GH-V (placental GH) and CSHs (chorionic somatomammotropins) are expressed (in human and probably chimpanzee) in the placenta; the CSHs comprise CSH-A, CSH-B and the aberrant CSH-L (possibly a pseudogene) in human, and CSH-A1, CSH-A2 and CSH-B in chimpanzee. Here the GH locus in two additional great apes, gorilla (Gorilla gorilla gorilla) and orangutan (Pongo abelii), is shown to contain six and four GH-like genes respectively. The gorilla locus possesses six potentially expressed genes, gGH-N, gGH-V and four gCSHs, whereas the orangutan locus has just three functional genes, oGH-N, oGH-V and oCSH-B, plus a pseudogene, oCSH-L. Analysis of regulatory sequences, including promoter, enhancer and P-elements, shows significant variation; in particular the proximal Pit-1 element of GH-V genes differs markedly from that of other genes in the cluster. Phylogenetic analysis shows that the initial gene duplication led to distinct GH-like and CSH-like genes, and that a second duplication provided separate GH-N and GH-V. However, evolution of the CSH-like genes remains unclear. Rapid adaptive evolution gave rise to the distinct CSHs, after the first duplication, and to GH-V after the second duplication. Analysis of transcriptomic databases derived from gorilla tissues establishes that the gGH-N, gGH-V and several gCSH genes are expressed, but the significance of the many CSH genes in gorilla remains unclear

The likelihood and magnitude of this process depends on the chemical nature and reactivity of the subglacial organic carbon stores. We examined the composition of carbon pools associated with different regions of the Greenland ice sheet (subglacial, supraglacial, proglacial) in order to elucidate the type of dissolved organic matter (DOM) present in the subglacial discharge over a melt season. Electrospray ionization (ESI) Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry coupled to multivariate statistics permitted unprecedented molecular level characterization of this material and revealed that carbon pools associated with discrete glacial regions are comprised of different compound classes. Specifically, a larger proportion of protein-like compounds were observed in the supraglacial samples and in the early melt season (spring) subglacial discharge. In contrast, the late melt season (summer) subglacial discharge contained a greater fraction of lignin-like and other material presumably derived from underlying vegetation and soil. These results suggest (1) that the majority of supraglacial DOM originates from autochthonous microbial processes on the ice sheet surface, (2) that the subglacial DOM contains allochthonous carbon derived from overridden soils and vegetation as well as autochthonous carbon derived from in situ microbial metabolism, and (3) that the relative contribution of allochthonous and autochthonous material in subglacial discharge varies during the melt season. These conclusions are consistent with the hypothesis that, given sufficient time (e.g., overwinter storage), resident subglacial microbial communities may oxidize terrestrial material beneath the Greenland ice sheet.This research was supported by: the National Science Foundation (CAREER-OCE- 0529101 (EBK), ARC-0520077 (SBD)), National Atmospheric and Space Administration (SBD), the WHOI Clark Arctic Research Initiative (EBK, SBD, MAC), the WHOI Ocean Ventures Fund (MPB), and the National and Science Engineering Research Council of Canada (MPB)
