Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy
Australian Journal of Public Administration, EarlyView.Abstract Collaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors ...

A “Tech First” Approach to Foreign Policy? The Three Meanings of Tech Diplomacy
Global Policy, EarlyView.ABSTRACT Scholars have recently argued that international politics is plagued by instability as the world rapidly transitions from one crisis to another. This state of “Permacrisis,” or permanent crises between states, is driven by technological innovations which create new kinds of crises and drive competitions between adversarial states.

War as a Phenomenon of Inquiry in Management Studies
Journal of Management Studies, EarlyView.Abstract We argue that war as a phenomenon deserves more focused attention in management. First, we highlight why war is an important and relevant area of inquiry for management scholars. We then integrate scattered conversations on war in management studies into a framework structured around three building blocks – (a) the nature of war from an ...

Effects of Configuration and Slot Angle of the Bleed System on the Performance of Hypersonic Inlet
气体物理, 2023 The numerical simulation of a typical two-dimensional hypersonic inlet was carried out to study the effects of configuration and slot angle of the bleed system on the performance of hypersonic inlet.
