Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

Global Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Iron Ore Pricing in China: Financialization Through a Marxist Lens

Abacus, EarlyView.
We offer a Marxist interpretation of financialization as we examine the Chinese market for iron ore and the shift in the pricing mechanism from an annual fixed price to an indexed price from 2010. Drawing upon Marx's theory of the circuit of capital, we illustrate an empirical case of financialization that results from the conflict between social ...
