High School GPA and Exam Scores: Does Their Relevance for First‐Year Academic Performance Vary With Program Selectivity?

open access: yesBulletin of Economic Research, Volume 78, Issue 4, Page 784-802, October 2026.
ABSTRACT This paper examines student admissions to higher education based on past performance, focusing on two measures: high school GPA and national exam scores. GPA is teacher‐assigned and based on repeated assessments, while these exams are externally graded, one‐off standardized tests. Using a nationwide dataset, we investigate how the relevance of

Scale‐Conditioned Geometry: How Measurement Resolution Induces Distance, Proximity, and Spatial Dependence

open access: yesGeographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT Scale is central to inference in natural and social systems, and geography and ecology have treated it as an explicit object of theory for decades. This paper builds on that work with a formal view in which scale is a degree of freedom of description, parameterizing both the mappings between representations and the metric defining distance and

Disaster Relief Through a Complex Adaptive System Perspective: Firms' Motivations, Activities, and the Role of Operations Adaptability in Overlapping Landscapes

open access: yesJournal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Natural disasters disrupt the normal functioning of both communities and businesses. However, past literature often segregates the disaster relief view from the business continuity perspective, leaving a gap in understanding how firms can proactively support relief efforts.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Dam Management in the Era of Climate Change

open access: yesMathematical Finance, Volume 36, Issue 4, Page 870-895, October 2026.
ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

Hole‐Activated Lattice Oxygen Enables Pt‐Free Propane Dehydrogenation by Eliminating the Hydrogen Recombination Bottleneck

open access: yesAngewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...
