Evolving Paradigms of Sustainability in Luxury Fashion: Evidence From an Emerging Market

Journal of Consumer Behaviour, EarlyView.
ABSTRACT The global fashion industry is both an economic driver and a major contributor of environmental and social challenges. This research examines how sustainable luxury fashion is constructed and adopted within an emerging market context by integrating perspectives from entrepreneurs, industry managers, and consumers.

Readily Accessible bTurea‐Derived Nitroxide Polarizing Agents for Dynamic Nuclear Polarization: bcTCOOKs and bcTmols

Chemistry – A European Journal, EarlyView.
Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Lasso for hierarchical polynomial models

Canadian Journal of Statistics, EarlyView.
Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

A Geometric Characterization of Steady Laminar Flow

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

The Governance Gap: Democratizing Drug Development Through Decision Architecture

Clinical Pharmacology &Therapeutics, EarlyView.
Drug development is most exposed to governance failure where it can least afford it, in global health. The field has more predictive power than at any point in its history and roughly the same failure rate it had a decade ago. We argue that this paradox persists because the field has invested heavily in prediction science while neglecting decision ...

Balancing Impartiality and Advocacy: Observations, Lessons, and Suggestions From a Practicing Ombuds

Conflict Resolution Quarterly, EarlyView.
ABSTRACT Universities increasingly rely on ombuds offices as informal, impartial mechanisms for addressing conflict and strengthening institutional trust. Yet the ombuds role is frequently shaped by tension among impartiality, advocacy, and legal accountability. This paper examines the evolution of the Office of the Ombuds at the University of Maryland,

A Meta‐Analytic Review of Board Characteristics and Carbon Emission Disclosure: The Moderating Effect of Contextual Factors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...
