Explains that health ideas and programs spread more successfully across countries when the people who created them and the people using them work together to modify them for new settings. Finds that this two-way collaboration—where developers refine the idea and local teams adapt it to their context—helps innovations travel between countries more fairly and effectively.

Examines how an “open streets” event (where roads are closed to cars) shapes the social atmosphere of a neighborhood, especially how people interact and use the space. It finds that these events tend to make neighborhoods feel more social and connected, encouraging people to spend time outside, interact with others, and build a stronger sense of community.

Explores how older adults understand and use wearable fitness technologies (like activity trackers) to support their health, focusing on their experiences and attitudes toward these tools. Finds that most older adults view them positively and feel they help increase awareness and motivate healthier behavior, but they also have some concerns (like risks or drawbacks) that can affect use. 

Examines how people participating in “open streets” events in cities across Latin America and the U.S. perceive their neighborhood environments before and during these events. Finds that these programs consistently make neighborhoods feel safer, more social, and easier to walk in, highlighting shared benefits like increased physical activity and stronger community connection across different locations.

Explores how low-income urban mothers think about walking and what would make it feel worthwhile in their daily lives. Finds that walking is often seen as a low priority or not even “real exercise,” so messages that focus only on health benefits don’t resonate—instead, framing walking as something that fits their routines or supports things they care about (like stress relief or time with others) is more motivating.
