A partially heterogeneous weighted fusion learning method for potential heterogeneous treatment effect in multi-site survival study

BMC Medical Research Methodology
Background In multi-site studies in clinical practice, the treatment effects may exhibit potential heterogeneity across different sites. Additionally, propensity score methods used to adjust for confounding may suffer from model misspecification, which ...

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

Journal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Detecting heritable phenotypes without a model using fast permutation testing for heritability and set-tests

Nature Communications, 2018
Standard approaches for heritability and set testing in statistical genetics rely on parametric models that might not hold in reality and give inflated p-values.

The Psychometric Properties and Clinical Usefulness of the Difficulties in Emotion Regulation Scale in Forensic Settings

Journal of Clinical Psychology, EarlyView.
ABSTRACT Objective The Difficulties in Emotion Regulation Scale (DERS) is a widely used measure of emotion dysregulation across clinical contexts. However, its psychometric properties and clinical utility have not been thoroughly examined in forensic populations.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Combating Farmland Degradation and Abandonment: The Rehabilitative Role of High‐Standard Farmland Construction in China

Land Degradation &Development, EarlyView.
ABSTRACT Farmland abandonment, driven by rapid urbanization and rural labor migration, has become a major catalyst for land degradation and threatens agricultural sustainability in China. While the High‐Standard Farmland Construction (HSFC) program was initiated to rehabilitate degraded soils and upgrade agricultural infrastructure, empirical evidence ...

Investigating item complexity as a source of cross-national DIF in TIMSS math and science

Large-scale Assessments in Education
Background Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or ...

DSGE Estimation Using Generalized Empirical Likelihood and Generalized Minimum Contrast

Entropy
We investigate the performance of estimators of the generalized empirical likelihood and minimum contrast families in the estimation of dynamic stochastic general equilibrium models, with particular attention to the robustness properties under ...

Are Academic Executives Greener? Evidence From China

Managerial and Decision Economics, EarlyView.
ABSTRACT This paper investigates the impact of executives with academic backgrounds (“academic executives”) on corporate green patents. We find that both the presence of academic executives and the proportion of academic executives have a significantly positive impact on firms' green patents, and this effect is positively associated with the firm's ...

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
