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, Volume 54, Issue 1, February 2026.
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.

Study on Fault Activation Evaluation Mechanism and Sensitivity Analysis in Shale Gas Hydraulic Fracturing

Geofluids, 2023
Shale gas hydraulic fracturing usually activates nearby faults and makes them slip. In horizontal wells, fault slip can result in serious casing deformation.

Investigation of Hydraulic Fracturing Behavior in Heterogeneous Laminated Rock Using a Micromechanics-Based Numerical Approach

Energies, 2019
Understanding hydraulic fracturing mechanisms in heterogeneous laminated rocks is important for designing and optimizing well production, as well as for predicting shale gas production. In this study, a micromechanics-based numerical approach was used to

Hardening and Hollowing Out Private Property: Rentiership, Dispossession, and Planetary Extraction in the Marcellus Shale

Antipode, Volume 58, Issue 1, January 2026.
Abstract Southwestern Pennsylvania (SWPA) has long been an energy extractive periphery, continuously remade through cycles of dispossession and accumulation. Here we examine the changing dynamics of private property in these cycles and its central role in the latest phase of extraction—unconventional oil and gas development (UOGD).

The 2021 Ms 6.0 Luxian (China) Earthquake: Blind Reverse‐Fault Rupture in Deep Sedimentary Formations Likely Induced by Pressure Perturbation From Hydraulic Fracturing

Geophysical Research Letters, 2023
To resolve the occurrence mechanism of the Luxian earthquake occurred near an active hydraulic fracturing well pad on 15 September 2021, we first use seismic waveforms to invert the focal mechanism solution and centroid depth, and then utilize Sentinel‐1

US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World

World Affairs, Volume 188, Issue 4, Winter 2025.
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Experimental Study on the Initiation and Propagation of Multi-Cluster Hydraulic Fractures within One Stage in Horizontal Wells

Energies, 2021
Competitive propagation of fractures initiated from multiple perforation clusters is universal in hydraulic fracturing of unconventional reservoirs, which largely influences stimulation.

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

Antipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact
