Weak Lensing Analysis of A2390 Using Short Exposures

The Astrophysical Journal
We present a weak lensing analysis of the galaxy cluster A2390 at z = 0.23 using second moment shape measurements made in 411 short 60 s exposures. The exposures are obtained in three broadband photometric filters ( g , r , and i ) using WIYN-ODI.

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs

Journal of Management Studies, EarlyView.
Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...

Self-Gravitating Systems in Extended Gravity

Galaxies, 2014
Starting from the weak field limit, we discuss astrophysical applications of Extended Theories of Gravity where higher order curvature invariants and scalar fields are considered by generalizing the Hilbert-Einstein action linear in the Ricci curvature ...

The simplicity of physical laws

Noûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Dark Matter Halos of Luminous Active Galactic Nuclei from Galaxy–Galaxy Lensing with the HSC Subaru Strategic Program

The Astrophysical Journal
We assess the dark matter halo masses of luminous active galactic nuclei (AGNs) over the redshift range 0.2–1.2 using galaxy–galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP).

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

Policy 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.

Embracing the politics of transformation: Policy action as “battle‐settlement events”

Review of Policy Research, EarlyView.
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.
