On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Asymptotic properties of cross‐classified sampling designs

open access: yesCanadian 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.

Mapping the Intellectual and Industrial Evolution of Corporate Social Responsibility: A Cross‐Sector Scientometric Analysis Using Main Path and Cluster Methods

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate social responsibility (CSR) has undergone continuous expansion across industries, yet its intellectual evolution and cross‐sectoral linkages remain insufficiently understood. This study provides a comprehensive, data‐driven assessment of CSR's developmental trajectories by analyzing 3314 Web of Science articles using key‐route main ...

Breaking Down Online and Digital Reporting Practices: A Research Map From Websites to Social Media

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper adopts a mixed research methodology, integrating bibliometric and systematic literature review (SLR) tools, to systematise the academic contributions and the different bodies of knowledge generated over the last decades on online and digital reporting practices, ranging from websites to social media.

Isoreticular Metal–Covalent Organic Frameworks With Engineered π‐Conjugation for Efficient Photocatalytic Hydrogen Production

open access: yesElectron, EarlyView.
By constructing an isoreticular Cu3‐cluster‐based metal–covalent organic framework platform with systematically tunable π‐conjugation, the physicochemical properties can be finely modulated within a well‐defined structural framework, thereby establishing a precise conjugation–performance correlation to govern the charge separation/transport, and thus ...

Altered neurostructural development in magnetic resonance imaging‐negative pediatric epilepsy: A large‐scale multicenter study of 1919 children

open access: yesEpilepsia, EarlyView.
Abstract Objective Addressing the poorly understood impact of pediatric epilepsy on neurodevelopment, this large‐scale study delineates age‐ and sex‐stratified neurostructural trajectories in magnetic resonance imaging (MRI)‐negative pediatric epilepsy to identify periods of maximal developmental divergence from healthy controls.

Baseline characteristics and feasibility of clinical outcome measures in CDKL5 deficiency disorder: The CANDID observational study

open access: yesEpilepsia, EarlyView.
Abstract Objective CDKL5 deficiency disorder (CDD) is a rare X‐linked developmental and epileptic encephalopathy caused by loss‐of‐function variants in the CDKL5 gene. Preclinical experiments using enzyme replacement or gene therapies show promise and could be transformative therapies.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).
