Behind Closed Doors: How Boardroom Silence and Implicit Theories Shape Corporate Governance

open access: yesCorporate Governance: An International Review, Volume 34, Issue 5, Page 1015-1035, September 2026.
ABSTRACT Research Question/Issue Why do directors, despite formal authority and oversight responsibilities, remain silent in the boardroom, and how does such silence shape governance outcomes? Research Findings/Insights Silence in boards is not a passive absence but a routinized governance practice.

Bolide light curve systematics from 75 recovered meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2351-2392, September 2026.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Seasonal Reversal of Polarity Dominance in High‐Current Cloud‐to‐Ground Return Strokes Over East Asian Midlatitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Extreme positive cloud‐to‐ground lightning over East Asian midlatitudes exhibits a spring–autumn double maximum hidden by the familiar winter climatology. Using 1,838,538 return strokes with absolute peak currents at least 200 kA during 2006–2024, we resolve its annual cycle by month and latitude.

Storm Structure and Lightning Characteristics of Tornado-hail-producing Supercell in Guangzhou on 27 April 2024

open access: yes应用气象学报
Due to the limited coverage of three-dimensional lightning detection networks, research on the total lightning characteristics of supercells that produce tornadoes and hail remains insufficient in China.

The Role of Lightning in Atmospheric Chemistry

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Lightning stroke clustering into cloud-to-ground lightning flashes

open access: yes, 2014
Cloud-to-ground stroke data have been analysed for the years 2010-2012 for the Cata- lan region. These strokes have been grouped together into lightning ashes using a hierarchical clustering method, with two di erent approaches to the clustering radius, as the objective of the study was to evaluate di erent clustering methods.

An enhancement of the ionospheric sporadic‐E layer in response to negative polarity cloud‐to‐ground lightning

open access: yes, 2008
Lightning data, collected using a Boltek Storm Tracker system installed at Chilton, UK, were used to investigate the mean response of the ionospheric sporadic-E layer to lightning strokes in a superposed epoch study.

Thunderstorm total lightning activity behavior associated with transmission line trip events of power system

open access: yesnpj Climate and Atmospheric Science
High-voltage transmission lines are susceptible targets for lightning strikes. It is an interesting topic how the trip event of transmission line is related to the area, location, and intensity of thunderstorms occurring at that time and that place ...
