Structural problems without structural solutions? Youth leaders' perceptions of their community

American Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

Improved Segmented Control Strategy for Continuous Fault Ride-Through of Doubly-Fed Wind Turbines

Energies
Aiming at the transient overcurrent problem faced by doubly-fed induction generators (DFIGs) during continuous voltage fault ride-through, a segmented control strategy based on the rotor side converter (RSC) is proposed.

Facilitators and barriers to neighborhood social integration

American Journal of Community Psychology, EarlyView.
Abstract Social isolation has reached concerning rates, particularly in the wake of the COVID‐19 pandemic. Social integration is critical to combatting social isolation and loneliness by promoting a sense of community and belonging. Yet, most existing research centers on fostering close personal relationships within family and friend networks.

Wind–Storage Coordinated Control Strategy for Suppressing Repeated Voltage Ride-Through of Units Under Extreme Weather Conditions

Energies
In practical engineering, large-scale wind power integration typically requires long-distance transmission lines to deliver power to load centers. The resulting weak sending-end systems lack support from synchronous power sources.

Parents' WhatsApp coping resources in the context of ongoing political conflicts: An ecological exploration

American Journal of Community Psychology, EarlyView.
Abstract Mobile technologies have become significant resources for crisis communication and social support in recent years. However, despite empirical evidence pointing to the centrality of these technologies for parenthood in everyday life, it is yet unknown how parents' coping resources play a role in the digital environment.

Neighborhood social environments and mental health among youth and adults in public housing

American Journal of Community Psychology, EarlyView.
Abstract Neighborhoods influence health in part through social processes. However, little is known about how multiple neighborhood social processes co‐occur, or about within (vs. between) neighborhood variation in social processes and health. This study asked how residents of a large public housing development describe their neighborhood and used ...
