Asymptotic independence in more than two dimensions and its implications on risk management
Canadian Journal of Statistics, Volume 54, Issue 1, March 2026.Abstract In extreme value theory, the presence of asymptotic independence signifies that joint extreme events across multiple variables are unlikely. Although well understood in a bivariate context, the concept remains relatively unexplored when addressing the nuances of simultaneous occurrence of extremes in higher dimensions.

Market Insurance and Risk Pooling in U.S. Crop Insurance
Agricultural Economics, Volume 57, Issue 2, March 2026.ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...

A Scale‐Invariant Learning Model for Distributed Practice Effects
Cognitive Science, Volume 50, Issue 3, March 2026.Abstract Despite their potential to significantly improve the durability of learning and their proven predictive power on many occasions, theories of distributed practice have not yet been widely adopted by educators. The reluctance may be attributed to the enormous strain they impose on learners or the fragmented nature of the evidence, as well as the

McDowell and Sellars on Objective Purport
European Journal of Philosophy, Volume 34, Issue 1, Page 313-332, March 2026.Abstract John McDowell has criticized Wilfrid Sellars on several occasions and over a number of years for his ‘non‐relational’ account of intentionality. This account is, according to McDowell, at least partly responsible for a ‘blind spot’ in Sellars's thinking: Sellars, allegedly, fails to see how objects or states of affairs in the external world ...

River, Volume 5, Issue 1, Page 33-54, February 2026.Study of meteorological‐hydrological drought propagation under reservoir regulation using a Copula‐Bayesian network in the Hanjiang River Basin. Abstract Reservoir operations play a pivotal role in modifying drought propagation processes, particularly by influencing the transition from meteorological to hydrological drought. This study investigates the

Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper proposes a novel bivariate odd beta prime Fréchet (BOBPF) distribution constructed through the application of the Farlie–Gumbel–Morgenstern (FGM) copula function. The new model, called the BOBPF‐FGM, is engineered to address the persistent challenge of modeling positively skewed and heavy‐tailed bivariate data that exhibit complex ...
