Defining Lines of Defense Against Change Propagation Using Cause‐Consequence Analysis
Systems Engineering, EarlyView.ABSTRACT Complex engineered systems are the core of modern society. So that engineered systems and infrastructure can be sustainable and offer value over the course of their lifespan, there is a growing need for such systems to be changeable. Yet, establishing and operationalizing changeability can be challenging due to the potential for change ...

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, EarlyView.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...
