International Journal of Urban and Regional Research, EarlyView.Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Dilemmas of Civilian Participation in Military Deterrence and Defence: Legal and Ethical Dimensions
Global Policy, EarlyView.ABSTRACT How can civilians participate in deterrence and defence in ways that do not jeopardize their immunity from deliberate attack? The principle of civilian immunity from deliberate attack in war is a core element of contemporary international humanitarian law (IHL). Uniformed combatants and others who take up arms pose a threat may be liable to be

A Protection Method for Inverter-based Microgrid Using Current-only Polarity Comparison
Journal of Modern Power Systems and Clean Energy, 2020 The design of an effective protection system for inverter-based microgrids is a complicated engineering challenge. This is due to the fact that inverters have limited fault current capabilities, and that the conventional overcurrent protection is not ...

A Practical Protection Coordination Strategy Applied to Secondary and Facility Microgrids
Energies, 2012 In a conventional distribution system, protection algorithms are designed to operate on a unidirectional high fault-current level. In a microgrid, a fault current from distributed generation (DG) may bring about a relay malfunction because of the ...

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.This paper presents a framework for Multiple Resilience Dividends (MRD) that proposes shift climate change adaptation from a narrow risk‐focused perspective to a broader, multi‐objective systems approach. By recognizing the diverse range of benefits that adaptation measures can provide, practitioners can go beyond merely avoiding losses.
