That's Not What I Was Promised! Psychological Contracts and Quiet Quitting
Human Resource Management, Volume 64, Issue 6, Page 1833-1863, November/December 2025.ABSTRACT The phrase “quiet quitting” has become a popular topic within the workplace and academia. However, the nomological network of quiet quitting is unclear. We contribute to quiet quitting research by incorporating organizational justice and job characteristics theories with a psychological contract and social exchange lens to illuminate ...

Chordal Graphs, Even‐Hole‐Free Graphs and Sparse Obstructions to Bounded Treewidth
Journal of Graph Theory, Volume 110, Issue 3, Page 351-365, November 2025.ABSTRACT Even‐hole‐free graphs pose a central challenge in identifying hereditary classes of bounded treewidth. We investigate this matter by presenting and studying the following conjecture: for an integer t ≥ 4 and a graph H, every even‐hole‐free graph of large enough treewidth has an induced subgraph isomorphic to either K t or H, if (and only if) H

The Burning Number of Directed Graphs: Bounds and Computational Complexity
Theory and Applications of Graphs, 2020 The burning number of a graph was recently introduced by Bonato et al. Although they mention that the burning number generalizes naturally to directed graphs, no further research on this has been done. Here, we introduce graph burning for directed graphs,

On the Cayley digraphs that are patterns of unitary matrices
, 2002 A digraph D is the pattern of a matrix M when D has an arc ij if and only if the ij-th entry of M is nonzero. Study the relationship between unitary matrices and their patterns is motivated by works in quantum chaology and quantum computation.

Infinite kernel perfect digraphs
AKCE International Journal of Graphs and Combinatorics, 2017 Let be a digraph, possibly infinite, V() and A() will denote the sets of vertices and arcs of , respectively. A subset of V() is said to be a kernel if it is both independent (a vertex in has no successor in ) and absorbing (a vertex not in has a ...

A systematic approach for identifying drivers of critical safety and establishing their hierarchy
The Canadian Journal of Chemical Engineering, Volume 103, Issue 10, Page 4628-4646, October 2025.Abstract Learning from incidents is a crucial step in preventing and mitigating adverse events. Incident databases offer valuable insights for safety management improvements by cause and contributing factors. However, extracting meaningful information from incident investigation reports poses a significant challenge. This study introduces a data‐driven

Tree-average distances on certain phylogenetic networks have their weights uniquely determined
Algorithms for Molecular Biology, 2012 A phylogenetic network N has vertices corresponding to species and arcs corresponding to direct genetic inheritance from the species at the tail to the species at the head.
