Welcome to the Jungle: An Examination of the Making of Science Standards

open access: yesScience Education, Volume 110, Issue 5, Page 1278-1301, September 2026.
ABSTRACT Nearly 50 million public school students in the United States are required to learn the content prescribed by state‐mandated science standards. Although much is known about the implementation of science standards and teachers' perceptions of them, the development process of these standards remains unclear.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

open access: yesThe Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Renewing Concerns of Technical Complexity in Accidents Research: An Argument to Retain Perrow's “First Thesis”

open access: yesJournal of Contingencies and Crisis Management, Volume 34, Issue 3, September 2026.
ABSTRACT It has been 40 years since Charles Perrow published the landmark work Normal Accidents ([1984]1999), built largely on an analysis of the Three Mile Island (TMI) nuclear power plant accident. While still a highly influential framework in the study of complex systems, the status of the argument remains in flux.

Seismo‐ and Tsunami‐Traveling Ionospheric Disturbances of the 29 July 2025 M8.8 Kamchatka Earthquake Observed by CW‐HF Doppler Sounding Systems and Ionosondes in Taiwan and Japan

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Doppler frequency shifts (DFSs) recorded by continuous wave‐high frequency Doppler sounding systems and ionograms observed by five ionosondes in Taiwan and Japan are used to study three‐dimensionally seismo‐ and tsunami‐traveling ionospheric disturbances (STIDs and TTIDs) triggered by the 29 July 2025 Mw8.8 Kamchatka earthquake.

Spiky Bursts of Energetic Electron Beams Upstream of Nonstationary Quasi‐Perpendicular Shocks

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Energetic electron beams play a crucial role in collisionless shocks by driving upstream plasma waves and providing seed populations for diffusive shock acceleration. However, the processes responsible for their generation at quasi‐perpendicular shocks remain poorly understood.
