Adaptive, but Equitable? Exploring the Impact of Machine Learning‐Based Adaptive Support on Educational Debts in Undergraduate Chemistry

open access: yesScience Education, EarlyView.
ABSTRACT Students' diverse levels of knowledge and competence—shaped by individual interests and educational debts, including structural, systemic, and institutional barriers—create substantial cognitive heterogeneity in instructional settings. Adequately addressing this heterogeneity is challenging.

When should firms watch for cross‐industry competition? A demand‐side perspective

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.

Better on Average? Average Inflation Targeting With an Unclear Averaging Window

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT Average inflation targeting (AIT) aims to stabilize inflation expectations by offsetting past deviations from target. However, ambiguity about the averaging window can complicate expectations formation and reduce policy effectiveness. This paper integrates AIT into a benchmark DSGE model, incorporating adaptive learning and a signal extraction

A new smooth failure criterion for concrete inspired by Lubliner's condition

open access: yesStructural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.
