A Multidimensional Resilience Capacity Index: Combining Composite Scoring With Complex Systems Methods

This paper proposes a novel two-lens hybrid framework that combines a weighted Resilience Capacity Index (RCI) with Self-Organizing Map (SOM) machine learning to create a multidimensional resilience measure that addresses key gaps in weighting, sensitivity analysis, validity, and configuration calculation without pre-assigned weights.

OCD-component for D-Optimal CRD with 6 and Some Odd Replications

This paper develops a new OCD-component for Completely Randomized Designs (CRD) with six and certain odd replications using covariate entries within the interval [-1, +1] (excluding zero), thereby achieving D-optimality while enabling the independent estimation of treatment and covariate effects, a condition previously unattainable with standard ±1 entries or zero-valued covariates.

National illicit amphetamine consumption in Germany from wastewater: Bayesian source apportionment, hold-out-evaluated extrapolation and monitoring design

This study employs a Bayesian mass-balance model with hierarchical extrapolation and rigorous hold-out validation on German wastewater data to estimate that national illicit amphetamine consumption in 2025 was approximately 16.8 tonnes, while highlighting significant discrepancies with traditional survey-based figures and demonstrating the critical need for monitoring smaller catchments to reduce estimation uncertainty.

Disaster, displacement, and distress: Earthquake intensity and persistent mental health effects in urban New Zealand

Using linked administrative data from Greater Christchurch, this study demonstrates that higher earthquake intensity causes persistent long-term increases in psychiatric medication use, with effects mediated by employment disruption for working-age adults and unobserved social factors for the elderly, highlighting the need for differentiated recovery policies.

Multiple Imputation Methods for Handling Missing Data under Treatment Policy Strategy: A Scoping Review

This scoping review identifies and summarizes various multiple imputation methods, including reference-based, retrieved dropout, return-to-baseline, and washout approaches, for handling missing data under the treatment policy strategy in randomized controlled trials, while mapping their underlying assumptions, limitations, and implementation to guide method selection and highlight areas for future research.

An Efficient Estimator of Population Mean Using a Poisson Regression-Based Approach: Simulation and Theoretical Efficiency Analysis

This paper proposes and validates a new Poisson regression-based estimator for the population mean under simple random sampling, demonstrating through theoretical analysis, empirical studies in environmental health and transportation safety, and simulations that it outperforms traditional ratio estimators in terms of mean square error.

Exposure-outcome window overlaps in biomarker studies: a simulation study and reporting checklist

This paper identifies and quantifies the bias introduced by exposure-outcome window overlaps in biomarker studies, demonstrating through simulations and a case study that standard analyses conflate prediction with contemporaneous severity, and proposes a reporting checklist to ensure transparency regarding latent event onsets and composite outcome components.
