What Is Science?

This work addresses the demarcation problem by proposing an axiomatic approach to distinguishing science from pseudoscience. It builds on three simple and intuitive axioms that characterize a consistent demarcation criterion. Neither Popper's falsification criterion nor the verif...

Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solut...

What Is Science? And What We Have Done to It with Hypothesis Testing

This work addresses the demarcation problem by proposing an axiomatic approach to distinguishing science from pseudoscience. It builds on three simple and intuitive axioms that characterize a consistent demarcation criterion. Neither Popper's falsification criterion nor the verif...

SOEP-LEE2: Data Updates and New Research Opportunities

Abstract The Socio-Economic Panel Linked Employer–Employee Survey, Version 2 (SOEP-LEE2), provides linked information on employees, establishments, and self-employed individuals in Germany. An earlier Data Observer article (Matiaske, Wenzel, Torben Dall Schmidt, Christoph Halbmei...

Boys Score Higher Everywhere? Gender Differences in Parent-Reported ADHD Symptoms Across Age Groups and Four Countries

Abstract Research suggests gender differences in parent-reported ADHD symptoms, but it remains unclear whether these differences vary across age group and countries. This study examined cross-national gender differences from early, middle and late childhood. Using a meta-analytic...

Multi-scale experimental and numerical analysis of thermal conductivity improvements in metal hydride composite systems

The inherently low thermal conductivity of metal hydrides significantly hinders heat transfer and, consequently, the kinetics of hydrogen absorption and desorption processes. To address this limitation, strategies such as adding high-thermal-conductivity materials have been explo...
