Evaluating the Substitution Value of Green Electricity for Advancing Renewable Energy Development Through the Value‐Added Contributions of Iran's Petrochemical Industries: A System Dynamics Approach

open access: yesEnergy Science &Engineering, EarlyView.
This study proposes a sustainable financing model for renewable energy in Iran by channeling petrochemical profits and carbon tax revenues into feed‐in tariffs. Reallocating natural gas from low‐efficiency power plants to high‐value petrochemical production enhances economic returns while reducing CO₂ emissions.

Overcoming the Paradox of Measuring Self‐Awareness Development by Focusing on Outcomes

open access: yesHuman Resource Development Quarterly, EarlyView.
ABSTRACT Many HRD interventions aim to enhance self‐awareness to shape employee behavior, to develop skills, or as a performance‐related outcome. But measuring this development faces significant metacognitive challenges: self‐awareness changes when one's attention is directed to it, and self‐report relies on accurate self‐awareness.
