Sensemaking and CSR Character in Multinational Corporations: A Comparative Study of Headquarters and Subsidiary Practices in the UAE

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT While corporate social responsibility (CSR) scholarship assumes that organizational consistency signals effectiveness, there remains a knowledge gap about how MNCs navigate competing institutional logics between headquarters and subsidiaries. This study investigates how managerial sensemaking mediates the effects of institutional pressures on ...

CSR Symbolism in Consumer‐Brand Identification in Fostering Brand Trust and Evangelism

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Based on the construal level theory, we proposed a conceptual model linking the relationships between perceived symbols in CSR communication, consumer‐brand identification, brand trust, and brand evangelism. We collected the data from the U.S. national population and employed an experimental design.

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.

A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.
