Annales de Didactique et de Sciences CognitivesWe examine how to foster a better appreciation of mathematics and science among trainee school teachers in order to improve their engagement in the teaching of scientific disciplines. To this effect, we adopt an approach based on the “polyvalence” of the

Small, EarlyView.Single‐particle‐level investigation using scanning tunneling spectroscopy reveals electronic structure and type‐I band alignment of individual CsPbBr3@FAPbBr3 core‐crown nanoplatelet. Crown passivation suppresses deep trap states by 47% and markedly improves electrical stability under repeated bias sweeps.

A Bilayer Rare‐Earth/High‐κ Oxide Memristor for Energy‐Efficient Neuromorphic Intelligence
Small, EarlyView.Interface‐engineered Gd2O3/HfO2 bilayer memristors demonstrate controlled filament formation, ultralow switching energy (∼13.56 pJ), and fast operation (∼350 ns) with a high ON/OFF ratio (∼107). The devices exhibit stable analog synaptic behavior and enable pattern recognition on Fashion‐MNIST, underscoring their promise for energy‐efficient ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab
Symbolic Interaction, EarlyView.How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Questioning Your Brilliance in Physics: Differential Shifts in Fixed Mindsets by Grade and Gender
Journal of Research in Science Teaching, EarlyView.ABSTRACT Students' domain‐specific mindsets and their beliefs about their capacity to improve through effort play a crucial role in shaping their experiences and decisions to persist in STEM disciplines. Physics is generally seen as a field requiring innate brilliance, which can reinforce fixed mindsets, particularly after initial setbacks in ...

Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022
Weather, EarlyView.UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine and influence the Central England Precipitation (CEP) and Central England Temperature (CET).

The Monterey Event and the Paleocene‐Eocene Thermal Maximum
Geophysical Monograph Series, Page 401-416., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
