Ensuring connectedness for the maximum quasi‐clique and densest k‐subgraph problems

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 3800-3824, November 2026.
Abstract Given an undirected graph G$G$, a quasi‐clique is a subgraph of G$G$ with density at least γ$\gamma$ (0<γ≤1)$(0 < \gamma \le 1)$. Two optimisation problems can be defined for quasi‐cliques: the maximum quasi‐clique (MQC) problem, which finds a quasi‐clique with maximum vertex cardinality, and the densest k$k$‐subgraph (DKS) problem, which ...

Attachment insecurity and psychological (mal)adjustment in older adults: The longitudinal role of fear of self‐compassion

open access: yesPsychology and Psychotherapy: Theory, Research and Practice, Volume 99, Issue 3, Page 931-945, September 2026.
Abstract Objectives Insecure attachment has been suggested to precede and perpetuate fear of self‐compassion, with a negative impact on mental health. However, this evidence was obtained using general‐age samples and cross‐sectional designs. Our objective was to, in an older adult sample, analyse longitudinally the indirect effect of fear of self ...
