Semi-Passive Control Strategy using Piezoceramic Patches in Non Linear Commutation Architecture for Structural-Acoustic Smart Systems

open access: yes, 2009
The demands for novel smart damping materials can be summarized in: external power source not required for operation; device not needing to be tuned to a specific frequency; device operation not affected by changes in modal frequency; device suppressing ...

Investigating Perceptions of the Eating Disorder Examination‐Questionnaire Among Undergraduate Students: A Qualitative Approach

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Quantitative methods that have evaluated the Eating Disorder Examination Questionnaire (EDE‐Q) have found consistent evidence that the original four‐factor structure does not replicate across diverse samples and genders. Emerging evidence in the broader psychology literature shows that qualitative methods can provide nuanced insight ...

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.

Varieties of Local Implementation for Net Zero in China: Evidence From Three Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Since China updated its nationally determined contributions in 2021, achieving carbon peaking before 2030 and carbon neutrality before 2060—the so‐called “dual carbon” goals—has become the new guiding principle of China's climate governance. However, few studies have examined the implementation of China's dual carbon goals, particularly the ...
