Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

Journal of Graph Theory, EarlyView.
ABSTRACT Given a graph G $G$, we say that an orientation D $D$ of G $G$ is a KT orientation if, for all u , v ∈ V ( D ) $u,v\in V(D)$, there is at most one directed path (in any direction) between u $u$ and v $v$. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as ...

On the Hardness of Switching to a Small Number of Edges

Journal of Graph Theory, EarlyView.
ABSTRACT Seidel's switching is a graph operation which makes a given vertex adjacent to precisely those vertices to which it was non‐adjacent before, while keeping the rest of the graph unchanged. Two graphs are called switching‐equivalent if one can be made isomorphic to the other one by a sequence of switches. Jelínková et al. [DMTCS 13, no. 2, 2011]

Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

Networks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, EarlyView.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate

Properly Colored Cycles in Edge‐Colored Balanced Bipartite Graphs

Journal of Graph Theory, Volume 112, Issue 2, Page 37-53, June 2026.
ABSTRACT Let G n , n c denote a (not necessarily properly) edge‐colored balanced bipartite graph on 2 n vertices, that is, in which every edge is assigned a color. A cycle C in G n , n c is called properly colored if any two consecutive edges of C have distinct colors.

When Science of Reading Meets Equity: Understanding and Applying Equity‐Oriented Models to Enhance a Phonics Intervention

Reading Research Quarterly, Volume 61, Issue 2, April/May/June 2026.
This graphical abstract illustrates how three equity‐oriented theoretical frameworks—the Asset‐Based Integrated View of Reading (ABIVR), Culturally and Historically Responsive Literacy (CHRL), and Adaptive Teaching—guided 39 pre‐ and in‐service teachers in identifying opportunities for enrichment and designing equity‐oriented adaptations to the Road to

A Proposal of Smooth Interpolation to Optimal Transport for Restoring Biased Data for Algorithmic Fairness

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.
ABSTRACT The so‐called algorithmic bias is a hot topic in the decision‐making process based on Artificial Intelligence, especially when demographics, such as gender, age or ethnic origin, come into play. Frequently, the problem is not only in the algorithm itself, but also in the biased data that feed the algorithm, which is just the reflection of the ...

Subset‐Row Inequalities and Unreachability in Path‐Based Formulations for Vehicle Routing and Scheduling Problems

Networks, Volume 87, Issue 2, Page 111-130, March 2026.
ABSTRACT This work considers branch‐price‐and‐cut algorithms for variants of the vehicle‐routing problem in which subset‐row inequalities (SRIs) are used to strengthen the linear relaxation. SRIs often help to substantially reduce the size of the branch‐and‐bound search tree.

Teaching Reading as a Complex and Multidimensional Process

The Reading Teacher, Volume 79, Issue 5, March/April 2026.
ABSTRACT This article examines the teaching of reading as a complex and multidimensional process amidst current approaches to teaching reading forwarded by new legislation and curricula that have been adopted across the United States. We underscore the importance of a comprehensive understanding of the teaching of early reading by bringing together ...

Unpacking Entrepreneurial Ecosystem Elements: Insights Into Drivers of Entrepreneurial Activity

Thunderbird International Business Review, Volume 68, Issue 1, Page 3-15, January/February 2026.
ABSTRACT Thriving entrepreneurial ecosystems (EEs) are instrumental in new enterprise creation and growth, as they provide vital support for entrepreneurial activity. However, as this support may be context‐specific, the existing literature has yet to capture the contextual factors that shape the contributions of EEs.
