Critical Pragmatism as a Paradigm for Nursing Research

open access: yesNursing Inquiry, Volume 33, Issue 3, July 2026.
ABSTRACT This manuscript explores critical pragmatism as a philosophical paradigm for nursing research. Critical pragmatism integrates the action‐oriented focus of pragmatism with the emancipatory aims of critical paradigms, offering a perspective that is both practically grounded and oriented toward social transformation.

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Energy Dependence of Energetic Electron Precipitation Rates Near the Foot of Electron Isotropy Boundary

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We report a rare quiet‐time observation by NOAA‐18 spacecraft flying nearly along the electron isotropy boundary (IBe). Complemented by data from four nearby meridional IBe crossings of other POES spacecraft, this case study provides a novel quantitative information concerning the regular energy dependence of the loss‐cone filling ratio (Jprec/

First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise energy range and the underlying physical mechanisms remain debated.
