Distributional justice and climate risk assessment: An analysis of disparities within direct and indirect risk

open access: yesRisk Analysis, Volume 45, Issue 11, Page 3354-3374, November 2025.
Abstract Climate change and natural hazard risk assessments often overlook indirect impacts, leading to a limited understanding of the full extent of risk and the disparities in its distribution across populations. This study investigates distributional justice in natural hazard impacts, exploring its critical implications for environmental justice ...

Bivariate Pell and Bivariate Pell-Lucas Hybrinomials

open access: yes
In this paper, we define bivariate Pell and bivariate Pell-Lucas hybrinomials and derive their recurrence relations. We obtain sequences of both the bivariate Pell hybrinomials and the bivariate Pell- Lucas hybrinomials and provide Binet formulas that ...
