Multiple Imputation of Missing Data in Structural Equation Models with Mediators and Moderators Using Gradient Boosted Machine Learning
… models are two commonly used models for indirect effects analysis. In practice, missing data is a pervasive problem in structural equation modeling with psychological data. Multiple imputation (MI) is one method used to estimate model parameters in the presence of missing data, while accounting …

Maintenance Policy Selection Using Fuzzy FMEA and Key Performance Indicators
… introduced for MPS using Fuzzy Failure Mode and Effects Analysis (FFMEA) and Fuzzy Analytical Hierarchy Process (FAHP). In the first step, a combination of FFMEA and FAHP are applied to calculate the risk of equipment. For the Risk Priority Number computation, three dimensions including Severity, …

Probabilistic risk assessment of system-level radiation effects
System-level radiation effects analysis is performed using a time-dependent Probabilistic Risk Assessment (PRA) methodology. Data-driven models for the expected behavior of radiation-sensitive parts are instanced in a system model for Fault Tree Analysis (FTA). The system model is then solved using …

Synergetic Effects of Democracy and Economic Development on Income Inequality and the Role of Relative Political Capacity
… as ordinary least squares regressions and fixed effects analysis, I argue that targeted policies addressing inequality can not only foster inclusive economic growth but also fortify the foundations of democratic institutions. As an additional dimension, a forthcoming regional case study focusing …
