open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Women's Off‐Farm Employment and Dietary Quality in Rural Africa

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Most households in rural Africa are involved in smallholder farming, but off‐farm employment is an important additional income source for many. Previous research has analysed links between off‐farm employment and well‐being, but mostly at the household level, not considering that household members may be affected differently.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Structural Basis for Trivalent Cross‐Linking of a Patient‐Derived IgE Antibody by the Major Peanut Allergen Ara h 2.0201

open access: yesAllergy, EarlyView.
Graphical The crystal structure of a major peanut allergen Ara h 2.0201 in a complex with a human‐derived IgE Fab fragment has been determined. The immunocomplex shows the trivalent binding of Fabs, creating a cross‐linked structure effective in the formation of large complexes on the surface of effector cells. Hydroxylation of proline has implications

Heterogeneous Effect of Cost‐Of‐Living Crisis: Evidence From South Korea

open access: yesAsian-Pacific Economic Literature, EarlyView.
ABSTRACT The global economy faced a severe cost‐of‐living crisis due to the War in Ukraine and COVID‐19‐related supply chain damages. However, the official Consumer Price Index, which represents the average changes, has limitations in drawing a fuller picture of actual heterogeneity for policymakers.

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

open access: yesBrain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...
