A Dichotomy Theorem for Γ ${\rm{\Gamma }}$‐Switchable H $H$‐Colouring on m $m$‐Edge‐Coloured Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Let G $G$ be a graph in which each edge is assigned one of the colours 1,2,…,m $1,2,\ldots ,m$, and let Γ ${\rm{\Gamma }}$ be a subgroup of Sm ${S}_{m}$. The operation of switching at a vertex x $x$ of G $G$ with respect to an element π $\pi $ of Γ ${\rm{\Gamma }}$ permutes the colours of the edges incident with x $x$ according to π $\pi $. We

Spanning Plane Subgraphs of 1‐Plane Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A graph drawn on the plane is called 1‐plane if each edge is crossed at most once by another edge. In this paper, we show that every 4‐edge‐connected 1‐plane graph has a connected spanning plane subgraph. We also show that there exist infinitely many 4‐connected 1‐plane graphs that have no 2‐connected spanning plane subgraphs.

From the Boardroom to the Jobsite: Female Board Representation and Workplace Safety

open access: yesJournal of Operations Management, EarlyView.
ABSTRACT Contributing to emerging research on corporate governance and operations management, our study examines the connection between board diversity and workplace safety. We propose that boards with a higher representation of female directors prioritize and thus enhance workplace safety due to women's distinct social‐cognitive perspectives on ...

PEG‐Free Nanoemulsions With Alkyl Polyglucoside and Baccharis dracunculifolia Essential Oil: Physicochemical Behavior, pH Dependence and Skin Repair Properties

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT Alkyl polyglucosides (APG) are biodegradable, non‐ionic surfactants from renewable sources with low ecotoxicity. This study developed a novel PEG‐free nanoemulsion (NE) using APG to encapsulate Baccharis dracunculifolia essential oil (BDO) for skin repair.

Real‐time quality assessment for Biogeochemical Argo radiometric profiles

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract An ever‐increasing number of Biogeochemical (BGC) Argo floats equipped with radiometric sensors have been deployed across the World Ocean. To date, more than 50,000 vertical profiles from 0 to at least 250 dbar of photosynthetically available radiation and downwelling irradiance at 3, narrow wavelengths have been acquired.
