Secure Enough? Sufficiency and Security in the New Geological and Geopolitical Reality

open access: yesSustainable Development, EarlyView.
ABSTRACT This article advances sufficiency theorizing by examining its relationship with security in the contemporary geopolitical context. It engages three contextually situated discourses: sustainable development, ecological civilization, and degrowth, to explore how concerns over ecological limits intersect with emerging geopolitical and security ...

Local Eviction Moratoria and the Spread of COVID‐19

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT At different stages during the initial onset of the COVID‐19 pandemic, various US states and local municipalities enacted eviction moratoria. One of the main aims of these moratoria was to slow the spread of COVID‐19 infections. We deploy a semiparametric difference‐in‐differences approach with an event study specification to examine whether ...

Simulation Analysis of Influencing Factors Assessment for Emergency Materials Supply Chain Resilience Based on System Dynamics

open access: yesSafety Science and Technology, EarlyView.
By integrating game theory‐based combined weighting with a system dynamics model, this study systematically reveals the dominant role of agility and adaptability in the resilience of post‐disaster emergency material supply chains. ABSTRACT In light of the intricate dynamics and uncertain risk parameters inherent in the emergency materials supply chains,

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

open access: yesStructural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.
