Guidelines for Meta‐Analytic Structural Equation Modeling: Steps, Resources, and Illustrations
Psychology &Marketing, EarlyView.ABSTRACT The goal of science is to build incremental, structured, and reliable knowledge over time. Yet, many strands of marketing and related disciplines exhibit symptoms of cumulative stagnation, including lack of replicability and weak theoretical integration. Existing remedies such as replication studies, multistudy investigations, and open science

Optimal Experimental Design for Fast and Accurate Relaxation Time Measurements in Magnetic Resonance
Magnetic Resonance in Chemistry, EarlyView.We apply D‐optimal experimental design to relaxation constant estimation in NMR relaxometry. The resulting sampling schedules concentrate measurements where the signal is most sensitive to the relaxation constant. Compared with conventional linear or logarithmic spacing, D‐optimal designs achieve better estimation accuracy and precision with fewer ...

Contemporary challenges in model misspecification
2024In contemporary practical applications, the significance of model misspecification has grown notably in many fields. When statistical inferences are based on likelihoods, model misspecification can give rise to inaccurate uncertainty quantification ...

Detection of Functional Form Misspecification in Cointegrating Relations [PDF]
A simple specification test based on fully modified residuals and the CUSUM test for cointegration of Xiao and Phillips (Journal of Econometrics, 2002) are considered as means of testing for functional form in long-run cointegrating relations.

Optimal Designs and Inspection Time Decisions for Gamma Accelerated Degradation Tests
Naval Research Logistics (NRL), EarlyView.ABSTRACT This study analytically derives optimal designs for gamma accelerated degradation tests while incorporating inspection time as a design variable under both D‐ and V‐optimality criteria. Under D‐optimality, we prove that the optimal design allocates test units exclusively to the lowest and highest stress levels and adopts the longest inspection

Nonprofit Management and Leadership, EarlyView.ABSTRACT I synthesize 78 studies from leading nonprofit and public administration journals to explain why research on board design choices, board effectiveness, and organizational performance yields inconsistent findings. The analysis reveals that empirical contradictions stem primarily from theoretical misalignment and measurement diversity rather ...

PLANTS, PEOPLE, PLANET, EarlyView.Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 435-447, March 2025.Abstract Intranasal diamorphine (IND), approved for managing breakthrough pain in the UK, has been identified as an acceptable alternative offering effective, expedient, and less traumatic analgesia for children. However, the current dose regimen in pediatric populations relies on clinical expertise while the pharmacokinetics properties are poorly ...
