Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

American Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Saturated flow boiling frictional pressure drop inside smooth macro and mini/micro channels: a new predictive tool using CatBoost and XGBoost

Case Studies in Thermal Engineering
Reliable prediction of the saturated boiling frictional pressure drop is fundamental to optimum evaporator design. Hence, frictional pressure drop is a critical parameter for improving the efficiency of the evaporator.

Food inflation pass‐through from agricultural imports in a small open economy

American Journal of Agricultural Economics, EarlyView.
Abstract This paper develops a new framework for quantifying cost pass‐through in a small open economy by estimating firm‐level markup responses to agricultural import price shocks. We show theoretically that markup adjustments depend on firms' reliance on imported inputs and demand curvature, generating heterogeneous inflationary effects across firm ...

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

American Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

The Made‐in‐Africa Evaluation framework: A decolonial approach to program evaluation

American Journal of Community Psychology, EarlyView.
Abstract The Made in Africa Evaluation (MAE) framework is a decolonial approach to program evaluation developed by African evaluators over the past 14 years. MAE may be appropriate to community psychologists who practice program evaluation or conduct research in Africa, but little is known about its implementation.

Clinical and Molecular Characterization of 46 Patients With Beckwith–Wiedemann Spectrum and Uniparental Disomy of 11p15

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder characterized by its main clinical features macrosomia, macroglossia, and abdominal wall defects. BWSp is caused by (epi)genetic chromosome 11p15 alterations with approximately 20%–27% of patients exhibiting mosaic paternal uniparental disomy of chromosome 11p15 (pUPD11p15).
