British Educational Research Journal, EarlyView.Abstract Research evidence is mixed on the consequences of ability grouping policies, but most research has found an overrepresentation of disadvantaged social demographics in low‐ability groups. However, researchers have neglected to explain why ability grouping policies vary between countries.

Infeasibility certificates for linear matrix inequalities
, 2011 Farkas' lemma is a fundamental result from linear programming providing linear certi cates for infeasibility of systems of linear inequalities. In semidefinite programming, such linear certificates only exist for strongly infeasible linear matrix inequalities. We provide nonlinear algebraic certificates for all infeasible linear matrix inequalities in

British Educational Research Journal, EarlyView.Abstract This article examines how UK and US universities manage racial equality regimes through governance structures that prioritise institutional reputation over substantive racial justice reform. Drawing on Bourdieu's field, habitus and capital theory, the study demonstrates how universities neutralise racial justice efforts through bureaucratic ...

Matrix rank/inertia formulas for least-squares solutions with statistical applications
Special Matrices, 2016 Least-Squares Solution (LSS) of a linear matrix equation and Ordinary Least-Squares Estimator (OLSE) of unknown parameters in a general linear model are two standard algebraical methods in computational mathematics and regression analysis.

Business Strategy and the Environment, EarlyView.ABSTRACT The apparel industry is one of the world's most profitable sectors but also among the most environmentally damaging. Growing sustainability pressures have led companies to adopt diverse strategies to reduce their impact, yet no single study has systematically analysed these approaches or their consumer implications.

Abstract and Applied Analysis, 2014 This paper addresses the finite-time bounded control problem of linear stochastic systems with state, control input, and external disturbance-dependent noise ((x,u,v)-dependent noise for short).

Business Strategy and the Environment, EarlyView.ABSTRACT The role of business towards achieving the 17 Sustainable Development Goals (SDGs) has been well established. However, SDG contextualization continues to pose a conundrum, particularly for firms operating in multiple contexts. This becomes even more problematic in the case of SDG 11, the only goal in the sustainable development agenda directly

Two Kantorovich-type inequalities and efficiency comparisons between the OLSE and BLUE
Journal of Inequalities and Applications, 2002 We first establish two matrix-determinant Kantorovich-type inequalities. Then we introduce two efficiency criteria and make efficiency comparisons between the ordinary least squares estimator and best linear unbiased estimator in linear models.

Business Strategy and the Environment, EarlyView.ABSTRACT The blue economy has emerged as a key sector for linking sustainability and innovation, yet existing research has largely overlooked how firms operationalize these processes in practice. This study addresses that gap by asking: How do Portuguese blue economy firms embed sustainability‐oriented innovation (SOI) into their strategies, and what ...
