“Building the Plane as We Fly It”: Examining the Current Pathways for Disclosure of Gender‐Based Violence in Sport in Australia

Gender, Work &Organization, EarlyView.
ABSTRACT This article examines how gendered institutional arrangements in Australian sport shape the reporting of gender‐based violence (GBV) against adult women and gender‐diverse people. Using feminist institutionalism, we analyze the formal and informal rules that structure sport integrity systems and the gendered power relations they reproduce ...

The ‘Geopolitical Commission’: 40 Years in the Making?

JCMS: Journal of Common Market Studies, EarlyView.
Abstract In 2019, European Commission President Ursula von der Leyen promised MEPs she would deliver a ‘Geopolitical Commission’ during the five years of her term in office, unbeknown that the COVID‐19 pandemic and the Russian invasion of Ukraine were around the corner.

High thermal conductivity of the Earth's core and geodynamo

Vestnik MGTU
The geomagnetic field is generated by dynamo processes in the Earth's core. This process is supported by the cooling of the planet and the growth of the solid core. It is known that the magnetic field existed long before the appearance of the solid core,

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Subducted Carbon From Mantle Plume in Mid‐Ocean Ridge Basalts

Geophysical Research Letters
Deciphering the Earth's deep carbon cycle, from mantle plumes to mid‐ocean ridges, remains incompletely understood. In this study, we analyze the magnesium isotope composition of basalts collected from the South Mid‐Atlantic Ridge (SMAR), which have been

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Periodontitis and Diabetes: Mechanistic Evidence of a Circular Relationship

Journal of Periodontal Research, EarlyView.
This narrative review aimed to explore the underlying mechanisms that connect periodontitis to diabetes (and vice versa) and that influence disease susceptibility, progression and response to treatment. ABSTRACT The circular relationship between periodontitis and diabetes mellitus is one of the most established oral‐systemic links.

Subduction‐Related Volcanic Activity as a Proxy for Global Subduction Flux Over the Past Billion Years, and Its Correlation With Geomagnetic Superchrons

Geophysical Research Letters
We investigate the frequency of subduction‐related volcanic events over the past billion years. Our analysis reveals distinct peaks and troughs interpreted as significant fluctuations in global subduction flux.
