Legitimacy in contested issue fields: How type‐based validity cues, cue congruence, and personal values shape propriety

open access: yesEuropean Management Review, EarlyView.
Abstract Contested business practices are often difficult to evaluate because they send multiple, often conflicting signals about their appropriateness. Some cues may suggest that a practice is useful, legal, or widely accepted, whereas others may suggest that it is risky, harmful, or socially opposed.

Stochastic Risk and Uncertainty Analysis for Shale Gas Extraction in the Karoo Basin of South Africa

open access: yesAbstract and Applied Analysis, 2014
We made use of groundwater flow and mass transport equations to investigate the crucial potential risk of water pollution from hydraulic fracturing especially in the case of the Karoo system in South Africa.

The “Fracking” technique: a novel approach to crack deep calcified plaque in the common femoral artery with hydraulic pressure

open access: yesCVIR Endovascular, 2021
Background The patency achieved by conventional peripheral interventions for atherosclerotic lesions in the common femoral artery (CFA), called the “no stenting zone”, is not superior to that achieved by surgical endarterectomy due to calcified plaque ...

Bring Out the Bulls: Employment Dynamics of Incumbent Trucking Firms During Highly Expansive Market Conditions

open access: yesTransportation Journal, Volume 65, Issue 4, Autumn 2026.
ABSTRACT Studying employment dynamics (e.g., the rates at which firms add or shed jobs) of trucking firms is critical to inform theory and public policy. We examine incumbent trucking firm employment dynamics during the highly expansive period of March 2020–March 2021, when the COVID‐19 pandemic delivered an exogenous shock, upending established ...

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

open access: yesGeofluids, 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

open access: yesEnergies, 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

Partisan Cities: How State‐Local Political Alignment Shapes Credit Risk and Information Processing in the Municipal Bond Market

open access: yesJournal of Accounting Research, Volume 64, Issue 4, Page 1733-1770, September 2026.
ABSTRACT This paper studies how partisan alignment between city leaders and state governors shapes information processing and bond pricing in the municipal bond market. Using a novel data set on 1,045 U.S. cities from 2005 to 2019, we show that cities with the same political affiliation as the state governor face 9 basis points lower borrowing costs ...

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4863-4878, 25 August 2026.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...

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

open access: yesGeophysical 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
