TL;DR: The results supported the proposition that perceived usefulness positively affects behavioral intention, yet it was determined that perceived ease of use was not a significant predictor of perceived usefulness.

TL;DR: It is suggested that external variables that affect perceived ease of use and usefulness need to be considered as important factors in the process of designing, implementing, and operating digital library systems to help decrease the mismatch between system design and local users' realities, and further facilitate the successful adoption ofdigital library systems in developing countries.

TL;DR: Light is shed on online social networking features in the context of health-related OSGs and practical lessons are provided on how to improve the capacity of OSGs to serve the needs of their users.

TL;DR: Findings show that those who were dissatisfied with the support they received from their current offline contacts were more likely to prefer social interaction in online support groups (OSGs), and use computer-mediated relationships as a possible alternative to offline support networks.

TL;DR: It is confirmed that perceived usefulness (PU) outweighs perceived ease of use (PEOU) in explaining actual use and suggested a feedback loop between PU and PEOU, which significantly improved the model fit at both global and local levels.
