Cruising Together: How the Europeans Tipped the Scales for the Ground‐Launched Cruise Missile

open access: yesGlobal Policy, Volume 17, Issue 3, Page 506-511, June 2026.
ABSTRACT In the 1970s, the United States adopted the ground‐launched cruise missile (GLCM) despite opposition from the military and the lack of an established military requirement. The case is, thus, at odds with common models of military innovation that rely on military utility and organizational interests for their explanatory power.

A Component-Decoupled and Physics-Constrained Hybrid Modeling Framework for Turbojet Engine Performance Prediction

open access: yesAerospace
Accurate turbojet engine performance prediction is crucial for condition monitoring, health management, and safe operation. Conventional component-level models require iterative solutions of strongly nonlinear matching equations and are sensitive to un ...

Task co‐use and product improvement: An organization design perspective

open access: yesStrategic Management Journal, Volume 47, Issue 5, Page 1433-1466, May 2026.
Abstract Research Summary Co‐using tasks—using the same task to produce more than one product—promises economies of scope. However, task co‐use also ties products together, changing a firm's task network by introducing cross‐product interdependencies. In light of these interdependencies, we identify an unrecognized downside of task co‐use for product ...

Explainable Remaining Useful Life Prediction Using Interpretable Divisive Feature Clustering

open access: yesApplied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.
ABSTRACT Accurate prediction of remaining useful life (RUL) is critical for effective predictive maintenance. While models like long short‐term memory (LSTM) are effective, they often lack interpretability, even when using explainable artificial intelligence (XAI) methods such as shapley additive explanations (SHAP).
