The benefits of Facebook 'Friends': the social capital implications of Facebook-enabled communication practices

Tuesday, 7 June 2011, 12:30 pm, Berkman Center, 23 Everett Street, second floor.

"This talk will provide an overview of research exploring the social capital implications of social network site use. Specifically, I will report on new research that attempts to identify specific Facebook-enabled behaviors that contribute to users' ability to access diverse perspective, novel information, and social support. This research explores the link between bridging social capital levels and Facebook-related factors such as time on site, the number of Facebook Friends, and a set of behaviors we call 'Cultivation of Social Resources.'"

Purposive / judgmental / selective / subjective research sampling

"To say you will engage in purposive sampling signifies that you see sampling as a series of strategic choices about with whom, where and how to do your research. Two things are implicit in that statement. First is that the way that you sample has to be tied to your objectives. Second is an implication that follows from the first, i.e., that there is no one 'best' sampling strategy because which is 'best' will depend on the context in which you are working and the nature of your research objective(s).

Purposive sampling is virtually synonymous with qualitative research. However, because there are many objectives that qualitative researchers might have, the list of 'purposive' strategies that you might follow is virtually endless, and any given list will reflect only the range of situations the author of that list has considered."
