The hitting time of rainbow connection number two

, 2012
In a graph $G$ with a given edge colouring, a rainbow path is a path all of whose edges have distinct colours. The minimum number of colours required to colour the edges of $G$ so that every pair of vertices is joined by at least one rainbow path is ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Bounds on coloring trees without rainbow paths

Discussiones Mathematicae Graph Theory
For a graph with colored vertices, a rainbow subgraph is one where all vertices have different colors. For graph $G$, let $c_k(G)$ denote the maximum number of different colors in a coloring without a rainbow path on $k$ vertices, and $cp_k(G)$ the maximum number of colors if the coloring is required to be proper.

Rainbow Connection In Sparse Graphs

Discussiones Mathematicae Graph Theory, 2013
An edge-coloured connected graph G = (V,E) is called rainbow-connected if each pair of distinct vertices of G is connected by a path whose edges have distinct colours. The rainbow connection number of G, denoted by rc(G), is the minimum number of colours

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Dual Connectivity in Graphs

Mathematics
An edge-coloring σ of a connected graph G is called rainbow if there exists a rainbow path connecting any pair of vertices. In contrast, σ is monochromatic if there is a monochromatic path between any two vertices.

Final‐year students' perspectives on socially responsive curricula in medical education: A qualitative case study

Medical Education, Volume 60, Issue 7, Page 770-781, July 2026.
Abstract Introduction There is urgency for health professionals to be better prepared to tackle health inequities. Transitioning to responsive and contextually relevant curricula is an important strategy to equip students to be both clinically competent and critically conscious of the contexts in which they provide health care.

Constructing Eco‐Responsible National Identities Through Collective Memory: Settler and Māori Histories of Environmental Change in Aotearoa New Zealand

Nations and Nationalism, EarlyView.
ABSTRACT A growing body of scholarship argues that collective memories of historical environmental change—formed and transmitted through museums, movies, novels, activist performances and other cultural texts and practices—can help nurture proenvironmentalism.

Middlebrow Aesthetics: An Explanation and Defense

Pacific Philosophical Quarterly, EarlyView.
ABSTRACT We offer a philosophical account of the middlebrow as a theoretical category to do explanatory and critical work in aesthetics. On our account, the middlebrow ought to be understood as aspirational popular art. That is, it is art which aspires both to be popular (in a distinctive sense), and at the same time to be something more than popular ...

Induced Subgraphs of Graphs with Large Chromatic Number IX: Rainbow Paths

The Electronic Journal of Combinatorics, 2017
We prove that for all integers $\kappa, s\ge 0$ there exists $c$ with the following property. Let $G$ be a graph with clique number at most $\kappa$ and chromatic number more than $c$. Then for every vertex-colouring (not necessarily optimal) of $G$, some induced subgraph of $G$ is an $s$-vertex path, and all its vertices have different colours.
