Determining impact angle from the spatial distribution of shock metamorphism: A case study of the Gosses Bluff (Tnorala) impact structure, Australia

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

Phenomenal knowledge and phenomenal causality

open access: yesNoûs, EarlyView.
Abstract There has been extensive debate over whether we can have phenomenal knowledge in the case of epiphenomenalism. This article aims to bring that debate to a close. I first develop a refined causal account of knowledge—one that is modest enough to avoid various putative problems, yet sufficiently robust to undermine the epiphenomenalist position.

Quantum Gravitational Collapse

open access: yes, 2005
We apply the recent results in Loop Quantum Cosmology and in the resolution of Black Hole singularity to the gravitational collapse of a star. We study the dynamic of the space time in the interior of the Schwarzschild radius. In particular in our simple model we obtain the evolution of the matter inside the star and of the gravity outside the region ...

A Three‐Stage Model of the Maturation of Nascent Policy Subsystems Toward Stable Advocacy Coalitions, With Evidence From the UK's Response to COVID‐19

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Policy subsystems are comprised of competing advocacy coalitions, in which public and private political actors with shared belief systems learn from each other and coordinate their strategies in the pursuit of influencing policy making in their favor.

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

open access: yesPolicy 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 ...
