Beyond Education and Occupation: Unpacking the Large Gender Wage Gap in Kenya

Uyanga Byambaa, Edward Miguel, Michael Walker, Samuel Zicheng Wang

Gender wage gaps persist globally, particularly in poor countries.Using Kenya Life Panel Survey data, we first document a raw gender wage gap of 79 log points (55%).We show it remains large, at 39 log points (32%), even controlling for a novel set …

Targeting Impact versus Deprivation

Johannes Haushofer, Paul Niehaus, Carlos Paramo, Edward Miguel et autres

A large literature has examined how best to target antipoverty programs to those most deprived in some sense (e.g., consumption). We examine the potential trade-off between this objective and targeting those most impacted by such programs. We work in the context of …

Dissection of the Ren6 and Ren7 powdery mildew resistance loci in Vitis piasezkii DVIT2027 using phased parental-progeny genomes and intraspecific locus graph reconstruction

Mélanie Massonnet, Rosa Figueroa‐Balderas, Noé Cochetel, Summaira Riaz et autres

The Chinese grape accession Vitis piasezkii DVIT2027 carries two loci associated with powdery mildew (PM) resistance loci, Ren6 and Ren7, which differ in timing and strength of response to Erysiphe necator. Both loci are consistent with recognition by intracellular immune receptors. To …

Clinical performance of a noninvasive melanoma rule-out test across Fitzpatrick skin types

Maral Skelsey, Brent Loftis, Mark D. Kaufmann, Daniel M. Siegel et autres

To the Editor: Numerous studies suggest that melanoma in individuals with higher Fitzpatrick skin types (FST) is more likely to present at an advanced stage and result in higher mortality.1 A noninvasive genomic rule-out test assessing gene expression of LINC00518 and PRAME …

Utilizing (Al, Ga)2O3/Ga2O3 superlattices to measure cation vacancy diffusion and vacancy-concentration-dependent diffusion of Al, Sn, and Fe in β-Ga2O3

Nathan D. Rock, Haobo Yang, Brian A. Eisner, A.D. Levin et autres

Diffusion of native defects such as vacancies and their interactions with impurities are fundamental to semiconductor crystal growth, device processing, and design. However, the transient equilibration of native defects is difficult to directly measure. We used (AlxGa1−x)2O3/Ga2O3 superlattices (SLs) to detect and …

Intergenerational Human Capital Impacts and Complementarities in Kenya

Madeline Duhon, Lia C. H. Fernald, Joan Hamory, Edward Miguel et autres

This study exploits experimental variation in parent human capital (early-life school-based deworming) and a shock to schooling (extended Covid closures) to estimate how these factors interact in the production of child human capital within a sample of 3,500 Kenyan 3-8 year olds.Parents …

A 55-Year-Old Man Undergoes an Esophagectomy for Esophageal Cancer. Two Years Later, He Develops Dysphagia and a Contrast Study Discloses a Narrowing at His Anastomosis. How Should This Be Investigated and Treated?

Michael Walker, John C. Fang

In the above case, radiologic evaluation has identified a stricture at the anastomosis from the previous esophagectomy. The main differential for this finding is a benign anastomotic stricture versus a recurrent malignant stricture. Dysphagia due to anatomical narrowing usually requires approximately 50% …

Real-World Performance of a Noninvasive Cutaneous Melanoma Rule-Out Test: A Multicenter U.S. Registry Study

Mark Kaufmann, Maral Skelsey, Laura K. Ferris, Michael Walker et autres

Introduction: Non-invasive adjuncts to visual assessment of pigmented lesions may reduce biopsies of benign lesions without compromising melanoma detection. A non-invasive genomic melanoma rule-out assay analyzes RNA extracted from stratum corneum cells for PRAME and LINC00518, two genes commonly expressed in melanomas …
