Anti‐Astrotropik — Outer Space, Technology and Resistance in the Tropics

Singapore Journal of Tropical Geography, EarlyView.
This paper traces an intellectual and geographical arc of thinking about outer space in the tropics, connecting Peter Redfield's Space in the Tropics: From Convicts to Rockets in French Guiana (2000), Sean T. Mitchell's Constellations of Inequality: Space, Race, and Utopia in Brazil (2017) and Asif Siddiqi's Cosmic Fragments: Dislocation and Discontent

What is a Multi‐Ethnic Party and How to Spot a Fake One?

Swiss Political Science Review, EarlyView.
Abstract Multi‐ethnic parties have been variously defined: as those which do not champion the interests of, or mobilize against, any specific ethnic group; as those with a recognisably cross‐communal leadership or membership; and as those which acquire some distribution of support across groups.

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

Terra Nova, EarlyView.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;
