Is That a Threat? How Types of Stakeholder and Reputational Threat Matter for Gaining Influence in Regulatory Rulemaking

Regulation &Governance, Volume 20, Issue 3, Page 1119-1135, July 2026.
ABSTRACT This paper assesses what type of comments are most useful to what type of stakeholder in gaining influence during public consultations. Theoretically, the paper approaches stakeholders' consultation comments as reputational threats from key audiences that the agency needs to respond to.

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Optimization in Conceptual Design of a BWB UAV Using an Adaptive Kriging‐Based Surrogate Model

Engineering Reports, Volume 8, Issue 2, February 2026.
An adaptive Kriging‐based framework for Blended Wing Body UAV optimization is presented. The exploitation‐oriented strategy yields a 14.5% range improvement, while sensitivity analysis identifies fuel mass as the dominant parameter for efficient conceptual design. ABSTRACT To improve optimization efficiency in the conceptual design of Blended Wing Body
