Asymptotic properties of cross‐classified sampling designs

Canadian Journal of Statistics, EarlyView.
Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

T‐calibration in semi‐parametric models

Canadian Journal of Statistics, EarlyView.
Abstract This article relates the calibration of models to the consistent loss functions for the target functional of the model. Correctly specified models are calibrated. Conversely, we demonstrate that if there is a parameter value that is optimal under all consistent loss functions, then a model is calibrated.

Functional inequalities involving special functions

Journal of Mathematical Analysis and Applications, 2006
Let \(_2F_1 (a,b;c;x)\) be a hypergeometric function and let \[ m(r) = {}_2F_1 (a,b;a+b;(1-r^2))/_2F_1 (a,b;a+b;r^2), \quad r \in (0,1). \] The author shows that \[ m(r) + m(s) \geq 2m[ \sqrt(1- \sqrt(( 1-r^2)(1-s^2)))]. \] If \(u_p\) is the generalized and normalized Bessel function and \(\sigma(r) = u_p(1 - r^2)/ u_p (r^2)\), the author proves that \[

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

Ngos' Contributions to Innovation: Innovation Enablers or Lead Innovators?

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores how non‐governmental organisations (NGOs) engage with innovation processes. Drawing on a comparative case study of two NGOs working in water sustainability, the paper analyses NGO involvement across seven stages of the innovation process.

Weak solutions for nonlocal evolution variational inequalities involving gradient constraints and variable exponent

Electronic Journal of Differential Equations, 2013
In this article, we study a class of nonlocal quasilinear parabolic variational inequality involving $p(x)$-Laplacian operator and gradient constraint on a bounded domain.

Board Composition, Sustainability Reporting, and the Moderating Role of a Contextual Issue: Evidence From an Emerging Country

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the impact of board composition (BC) on sustainability reporting (SR) in financial firms listed on the Dhaka Stock Exchange (DSE), with a focus on the moderating role of non‐performing loans (NPLs). Using 421 firm‐year observations from 49 firms (2016–2024) and an ordinary least squares (OLS) regression model, the results ...

From Compliance to Collaboration: Towards a Strategic Framework for Social Sustainability in Fashion Supply Chains—Insights From a Two‐Phase Literature Review

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The purpose of this study is to provide a comprehensive longitudinal analysis of the evolution of social sustainability within the global textile and fashion industry across two distinct regulatory eras: post‐Multifibre Agreement (2005–2018) and post‐Modern Slavery Act (2019–2023).

Understanding Consumer Behaviour and the Circular Economy Transition in Sustainable Fashion: A Systematic Literature Review

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The fashion industry plays a key role towards global sustainability goals, yet remains among the most sustainability‐impacting sectors. Since 2020, several disruptions—including the Covid‐19 pandemic, geopolitical instability, and ambitious sustainability policies—have dramatically reshaped how consumers interact with fashion. In response, the
