Reducing teachers’ perceived stress through an online wellbeing intervention: the role of socio-emotional competence and self-efficacy

Introduction: Teaching is a profession characterized by high emotional demands and exposure to multiple stressors, often leading to elevated levels of perceived stress. Self-efficacy and socio-emotional competence have been identified as key protective resources that enable teachers to cope more effectively with professional challenges. The present quasi-experimental study evaluated the effectiveness of an Online Wellbeing Course (OWC) in enhancing teachers’ socio-emotional competence and sel...

Education and Inequality:

This paper compares Thomas Piketty’s Capital and Ideology and Bowles and Gintis’ Schooling in Capitalist America, examining their views on the role of education in perpetuating economic inequality. Despite irreconcilable theoretical foundations, both works converge on a critical conclusion: education intensifies rather than mitigates inequality, particularly through intergenerational wealth transmission and hypocritical meritocracy. With regards to intergenerational inequality, we discuss it...

An output feedback control based on extended high-gain observer for active vibration control systems with nonlinear Galfenol-based actuators

This paper proposes an output feedback control for Galfenol-based actuators in active vibration control systems, capable of addressing complex challenges such as unknown actuator dynamics, unmodeled external disturbances, hysteresis, and varying loads. The main contribution is to develope an output feedback controller that ensures the actuator produces compensatory forces to effectively suppress unwanted platform motion, achieving zero displacement at the output using only the measured positi...
