What Drives CSR Performance: Structures, Declarations or Values?
ABSTRACT Sustainability and corporate social responsibility (CSR) are increasingly central to strategic management, yet a gap persists between formal commitments and actual practice. The study explores the structural and value‐based predictors of the institutional integration of CSR and sustainability, with a focus on the mediating role of the CSR ...

Nonparametric Estimation of Quantile-Based Mean Inactivity Time Function
In this article, we propose non-parametric estimators for mean inactivity time function for complete and censored data. The asymptotic properties of the estimators are established using suitable regularity conditions.

Nonparametric estimators for varextropy under $\alpha$-mixing condition with appliction in exponential AR(1) model [PDF]
The goal of this paper is to study the problem of estimation of varextropy function under $\alpha$-mixing dependence condition. We propose nonparametric estimators for varextropy, residual varextropy and past varextropy.

Asymptotics of regular convolution quotients [PDF]
The asymptotic behaviour of a class of generalized functions, named regular convolution quotients, has been defined and analysed. Some properties of such asymptotics, which can be useful in applications, have been proved.

ABSTRACT Public organisations often experience a discrepancy between improvements in technical efficiency and stakeholders' perceptions of integrity and performance. This study analyses the mechanisms that may underlie this efficiency–perception discrepancy in Spanish Defence Delegations during 2020–2023.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Rocking and Rolling of Rigid Polygons Under Seismic Excitation
ABSTRACT We present an event driven analytical framework for rigid cyclic polygons subjected to horizontal ground excitation in which uplift, impact, and successive pivot switching are treated within a unified non‐smooth dynamical description. Rolling is defined as a sequence of energetically admissible transitions between neighbouring vertices tied to

Asymptotic sufficiency. I: Regular cases
Higher order asymptotic sufficiency is investigated in the classical parametric iid case: the parameter is finite-dimensional, the support of the distributions does not depend on the parameter, and the log- likelihood is a smooth function of the parameter. For the concept of higher order asymptotic sufficiency see \textit{J. K.

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.
