Teachers and friendship study

Students learning in classrooms in which they perceive teachers as warm, respectful and trustworthy may be more likely to form and continue interracial friendships, according to a recent study.What’s more, students’ perceptions of their teachers—who may treat children in the same class differently, for example—influenced the rate of growth in same-race friendships from the fall to the spring. "When teachers [show] that everyone is valued ... that everyone deserves warmth and support, then that trickles down to the students, particularly at this age," said  the study's lead author.

Blogging study

Blogging for sanity
Blogging can help you feel less isolated, more connected to a community, and more satisfied with your friendships, both online and face-to-face, Australian research has found. The study found that after two months of regular blogging, people felt they had better social support and friendship networks than those who did not blog.
