Development and Change, Volume 57, Issue 2, Page 315-338, March 2026.ABSTRACT Sierra Leone's land governance reform policies are often based on the neoliberal assumption that market growth, gender equality and women's empowerment are mutually compatible objectives. Contrary to this assumption, this article argues that while market‐oriented reforms can help to destabilize legal and cultural norms that are discriminatory ...

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins
AGU Advances, Volume 7, Issue 1, February 2026.Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Reconciling Seismic and Thermo‐Chemical Models of Cratonic Lithosphere
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract Most published global and regional shear‐wave (VS ${V}_{\mathrm{S}}$) velocity models of cratons include a VS ${V}_{\mathrm{S}}$ increase with depth below the Moho, with a maximum at 100–150 km depth. This feature has long been debated, as it appears to require either (implausible) temperature decreases with depth, or substantial, layered ...
