Murdering Crows: Pauli Murray, Intersectionality, and Black Freedom

What is intersectionality’s origin story and how did it make its way into human rights? Beginning in the 1940s, Pauli Murray (1910–1985) used Jane Crow to capture two distinct relationships between race and sex discrimination. One Jane used the race-sex analogy to show that race and sex were both unconstitutionally arbitrary. The other Jane captured Black women’s experiences and rights deprivations at the intersection of race and sex. Both Janes were based on Murray’s fundamental belief that the struggles against race and sex discrimination were different phases of the fight for human rights. In 1966, Murray was part of the American Civil Liberties Union team that litigated White v. Crook. In White, a three-judge federal district court panel declared Lowndes County, Alabama’s jury selection process discriminated against the county’s Black residents based on both race and sex in violation of the Fourteenth Amendment. What appeared to be an intersectional victory for Black women, was, in fact, an analogical victory for white women. The reasoning and the remedy erased the Black women litigants and the Lowndes County Black Freedom Movement, both of which were essential to the litigation. By situating White in the context of the Lowndes County movement, this Article demonstrates the centrality of Black feminist praxis to the county’s Black Freedom politics. The women in the movement took aim at Jane Crow which personified their intersectional experiences. Freedom for the county’s Black female majority did not require white women’s subjugation. By contrast, white women’s equality was a claim to share power with white men which included the power to maintain Jim and Jane Crow. Therefore, intersectional Jane and analogical Jane were on opposite sides of the fight for Black freedom in Lowndes County where white Jane’s equality required Black Jane to remain unfree

Unseen, Unheard: a Qualitative Analysis of Women’s Experiences of Exclusively Expressing Breast Milk

Background Breast milk feeding has numerous benefits for women and infants. Positive maternal experiences with breast milk feeding impacts exclusivity, duration, and maternal mental health. Most research focuses on women feeding directly at the breast. Some women elect to feed exclusively expressed milk to their healthy, term infants rather than feed directly at the breast. Little is known about what constitutes a positive experience among this population. Therefore, the aim of this study was to explore women’s experiences of exclusive expression (EE). Methods Interviews were conducted via Microsoft Teams to collect qualitative data from a purposive sample of 21 women practicing EE. Interviews were analyzed for themes. Results Three themes: Unseen and Unheard, Doing it My Way, and Getting into the Groove, and 8 subthemes: Breast is Best, Missed Opportunities for Healthcare Provider Support, Fighting for it, What Works for Us, A Sense of Control, Preparation, Tricks of the Trade, and Making it Manageable were identified. Despite challenges, including a lack of support from healthcare providers and a lack of acknowledgement as breastfeeding mothers, exclusive expression offered participants a method to continue breast milk feeding in a way that they found to be satisfying. Conclusion This study provides insight into experiences of exclusive expression that clinicians can use to improve their support of breast milk feeding during perinatal encounters. Societal pressure to feed from the breast may have negative emotional consequences for women electing to exclusively express. There is a need for more information and support for breast milk expression from healthcare providers along with a reframing of how breast milk feeding is discussed and promoted

Valuing Children's Fatality Risk Reductions

The estimates used by U.S. Federal agencies and others to value reductions in fatality risks generally reflect adults’ willingness to trade income for changes in their own risks. Several studies have now been completed that address the value of risk reductions to children. We review these studies for quality and applicability based on selection and evaluation criteria derived from recent discussions of best practices. To limit the effects of between-study variability, we searched for studies that estimate values for both adults and children using a consistent approach. We find seven studies that meet our selection criteria. The studies suggest that the value for children exceeds the value for adults by a factor of 1.2 to 3.0, with a midpoint of 2.1. Studies that estimate the value of reductions in nonfatal risks lead to similar results. Although some studies suggest that the divergence between child and adult values may decrease as the child ages, more work is needed to determine the extent to which these multipliers vary across age groups

The economics in 'Global Health 2035': a sensitivity analysis of the value of a life year estimates

In “Global health 2035: a world converging within a generation,” The Lancet Commission on Investing in Health (CIH) adds the value of increased life expectancy to the value of growth in gross domestic product (GDP) when assessing national well-being. To value changes in life expectancy, the CIH relies on several strong assumptions to bridge gaps in the empirical research. It finds that the value of a life year (VLY) averages 2.3 times GDP per capita for low- and middle-income countries (LMICs) assuming the changes in life expectancy they experienced from 2000 to 2011 are permanent. We investigate the sensitivity of this estimate to the underlying assumptions, including the effects of income, age, and life expectancy, and the sequencing of the calculations. We find that reasonable alternative assumptions regarding the effects of income, age, and life expectancy may reduce the VLY estimates to 0.2 to 2.1 times GDP per capita for LMICs. Removing the reduction for young children increases the VLY, while reversing the sequencing of the calculations reduces the VL

The H-alpha and Infrared Star Formation Rates for the Nearby Field Galaxy Survey

We investigate the H-alpha and infrared star formation rate (SFR) diagnostics for galaxies in the Nearby Field Galaxy Survey (NFGS). For the 81 galaxies in our sample, we derive H-alpha fluxes (included here) from integrated spectra. There is a strong correlation between the ratio of far-infrared to optical luminosities L(FIR)/L(H-alpha) and the extinction E(B-V) measured with the Balmer decrement. Before reddening correction, the SFR(IR) and SFR(H-alpha) are related to each other by a power-law. Correction of the SFR(H-alpha) for extinction using the Balmer decrement and a classical reddening curve both reduces the scatter in the SFR(IR)-SFR(H-alpha) correlation and results in a much closer agreement (within ~10%) between the two SFR indicators. This SFR relationship spans 4 orders of magnitude and holds for all Hubble types with IRAS detections in the NFGS. A constant ratio between the SFR(IR) and SFR(H-alpha) for all Hubble types, including early types (S0-Sab), suggests that the IR emission in all of these objects results from a young stellar population.Comment: 23 pages, 5 figures, 1 table. Accepted for publication in the Astronomical Journal. V2: Important changes: IRAS fluxes updated. Only moderate and good quality IRAS FIR fluxes are now used, resulting in slight changes to the equations and figures. The IR and H-alpha SFRs now agree to within ~10%, rather than ~30% as quoted previousl

Interactive technology use and child development: A systematic review

Background There is mixed evidence regarding the impact of interactive digital devices on child development. Tentatively some studies suggested that the use of digital devices may correlate negatively with language, executive function, and motor skills. However, attempts to amalgamate this evidence has been limited related to the available number of experimental and cohort studies that have evaluated the impact of digital technology use on child development. We conducted this review to determine the impact of interactive digital devices on child development among children aged 7 years or younger. Interactive technology has been defined as methods, tools, or devices that users interact with in order to achieve specific tasks. Data Source To carry out this systematic review, databases CINAHL, MEDLINE, Embase, PsychINFO, Scopus and Google Scholar were searched for relevant studies. Study Selection We used the Joanna Briggs Institute methodology for systematic reviews. Data Extraction Data extraction and synthesis was carried out by two reviewers and checked by a third reviewer. Studies were stratified into tiers depending on the level of evidence provided and the domain of development assessed. Results Fifty-three studies were eligible for inclusion in the review, 39 Tier 1 (randomized controlled trials and quasi-experimental studies) and 16 Tier 2 (descriptive studies). Children\u27s use of interactive digital technology was positively associated with receptive language and executive function and negatively associated or unrelated to motor proficiency. Other critical aspects informing the evidence, such as dose of exposure, intensity, or duration, were inconsistently reported, making estimates of exposure tentative and imprecise. Conclusion The studies included in this review were predominantly correlational or comparative in nature and focuses on cognitive domains of learning rather than a specific developmental outcome. It is difficult to generalize our findings beyond the digital devices or applications that have been evaluated by earlier studies. The contextual factors that may moderate the relationship require elaboration in future studies

Science Identity Development Trajectories in a Gateway College Chemistry Course: Predictors and Relations to Achievement and STEM Pursuit

This investigation of undergraduates’ heterogeneous science identity trajectories within a gateway chemistry course identified three latent classes (High and Stable, Moderate and Slightly Increasing, Moderate and Declining) using growth mixture modeling. Underrepresented minorities were more likely to exhibit Moderate-and-Slightly-Increasing science identities versus High-and-Stable patterns. Students with higher perceived competence were more likely classified into the High-and-Stable class compared to the other classes. Students classified into the High-and-Stable class scored significantly higher on the final exam and appeared to be more likely to remain in a STEM major across fall and spring semesters compared to the other two classes. Results suggest that some students’ identities shift within a single semester and supporting science perceived competence before college may support students’ science identity development
