Context‐free graphs and their transition groups

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

Bring Out the Bulls: Employment Dynamics of Incumbent Trucking Firms During Highly Expansive Market Conditions

Transportation Journal, Volume 65, Issue 4, Autumn 2026.
ABSTRACT Studying employment dynamics (e.g., the rates at which firms add or shed jobs) of trucking firms is critical to inform theory and public policy. We examine incumbent trucking firm employment dynamics during the highly expansive period of March 2020–March 2021, when the COVID‐19 pandemic delivered an exogenous shock, upending established ...

Occupational Licensing and Psychologist Supply

Health Economics, Volume 35, Issue 9, Page 1288-1305, September 2026.
ABSTRACT Does reducing interstate licensing barriers increase the supply of mental health providers? We study this question using the U.S. Psychology Interjurisdictional Compact (PSYPACT), which allows psychologists to practice across state lines via telemedicine without obtaining additional state licenses.

Complete Chloroplast Genome of Indonesian Sugarcane (Saccharum ‘Bululawang’): Comparative, Structural, and Evolutionary Analysis of Photosystem I‐Encoding Genes

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Sugarcane is one of the most important crops, providing the majority of global sugar production and serving as a major feedstock for bioenergy. Increasing demands for sustainable sugar production under climate and productivity constraint have intensified the need for molecular‐level characterization of elite cultivars.

School Entry Deferral: Effects of Age and Schooling on Children's Longitudinal Executive Function Development and Parent‐Reported Socio‐Emotional and Regulatory Outcomes

Developmental Science, Volume 29, Issue 5, September 2026.
ABSTRACT Whether an optimal school‐entry age exists is widely debated. A sequential cohort longitudinal design was used to investigate how school‐entry deferral affected executive function development, and parent‐reported socio‐emotional and self‐regulatory outcomes in 110 children (majority White) over one academic year.

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together

Ethology, Volume 132, Issue 9, Page 604-622, September 2026.
The present review underscores two salient points: In the context of evolutionary transitions to pair‐ and group living, it is imperative to acknowledge the distinction between selective forces that act during the origin of these social systems and those that act during their subsequent maintenance.
