The Forthcoming General Election in the Republic of Ireland: Winds of (Left‐Wing) Change or Plus Ça Change?

The Political Quarterly, Volume 96, Issue 1, Page 180-188, January/March 2025.
Abstract The forthcoming general election will be the most consequential electoral contest for the Republic of Ireland in a century. The polity is situated in truly novel territory with the potential for an historic first: the incoming of a Sinn Féin‐led, left‐wing government.

Reflection and transmission of seismic waves under initial stress at the earth's core-mantle boundary

International Journal of Mathematics and Mathematical Sciences, 1980
In the present paper the influence of the initial stress is shown on the reflection and transmission of P waves at the core-mantle boundary. Taking a particular value of the inherent initial stress, the variations of reflection and transmission ...

Melting Curve and Phase Relations of Fe‐Ni Alloys: Implications for the Earth's Core Composition

Geophysical Research Letters, 2020
Nickel is the second most abundant element in the Earth's core. However, the properties of Fe‐Ni alloys are still poorly constrained under planetary cores conditions, in particular concerning the effect of Ni on the melting curve of Fe. Here we show that

Carbon-driven Chemical Interactions between Alumina and Iron: A possible reaction pathway in Earth's interior [PDF]

, 2008
Seismological and geochemical observations have revealed a complex structure for the earth's core-mantle boundary (CMB) region, with lateral and chemical heterogeneities.

The lithosphere-asthenosphere boundary in the North-West Atlantic region [PDF]

, 2005
A detailed knowledge of the thickness of the lithosphere in the north Atlantic is an important parameter for understanding plate tectonics in that region.

Atlas of the underworld: Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity [PDF]

, 2018
Across the entire mantle we interpret 94 positive seismic wave-speed anomalies as subducted lithosphere and associate these slabs with their geological record.

Carney's Davos Address and the (Contested) Re‐Imagining of Middle Powers

Global Policy, EarlyView.
ABSTRACT By privileging the intervention of Canada's prime minister, Mark Carney, in his January 2026 Davos address, the work aims to re‐engage with the debate around middle powers extending from academic scrutiny to instrumental practice. On core themes, Carney's address provides exceptional focal points pertaining to the role of this category of ...

Influence of Grain Size Evolution on Mantle Plume and LLSVP Dynamics

Geochemistry, Geophysics, Geosystems
Recent seismic tomography models suggest large‐radius primary plumes originating from the core‐mantle boundary, with grain size variations potentially explaining these observations. Additionally, grain size variations are thought to enhance the long‐term

Emollient Formulations and Skin Barrier Practices in the Context of Eczema and Food Allergy Prevention

Allergy, EarlyView.
ABSTRACT The skin is far from a passive shield; it functions as a dynamic “living barrier” whose structural and immunological integrity is paramount in preventing atopic dermatitis (AD) and the subsequent progression of the atopic march toward food allergy (FA).
