Canadian Public Administration, Volume 69, Issue 2, Page 250-277, June 2026.Abstract The war in Ukraine and Israel's successful operations have demonstrated the apparent shift in military operations, strategic defence spending, and innovations. Drawing parallels to the industrial revolution and how it slowly transferred military procurement, training, and deployment, the current study also highlights the AI revolution and the ...

New Technology and Work: AI and the Coming Struggle to Democratise Work Organisation
Sociology Compass, Volume 20, Issue 6, June 2026.ABSTRACT This paper explores AI‐related changes at work and considers the adequacy of our conceptual tools in the light of contemporary advances in AI. These considerations raise the question of whether sociologists of work should engage more in advocating for worker voice in technology decision‐making. Using the concept of work organisation, I draw on
