Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Using Cultural Theory to Specify the Policy Actors, Belief Systems, and Sources of Coalition, Conflict, Stability, and Change in Policy Advocacy Coalitions and Environmental Resource Policies

Policy Studies Journal, EarlyView.
ABSTRACT We use grid‐group cultural theory (CT) to specify underspecified aspects of the Advocacy Coalition Framework (ACF). Our theoretical synthesis of CT and the ACF provides, first, an exhaustive typology of policy actors and their cultural cognitive biases that entail, guide, and constrain policy core beliefs about problem definitions and ...

Tariff: The Most Beautiful Word in the Dictionary?

Review of International Economics, EarlyView.
ABSTRACT We consider the welfare impacts of US tariff policy at levels proposed by President Donald J. Trump. General‐equilibrium simulations under a widely used transparent one‐sector trade model reveal sizable US welfare losses. When we extend the model to include bilateral firm selection and high resolution input–output linkages, the US losses ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...
