Gameboys and Gadget Girls: Separate Spaces, Parallel Play

Megan Ellis
Even though women play video games in nearly equal numbers to men, play a variety of games ranging from ‘hardcore’ AAA games to ‘casual’ mobile games, and dedicate a significant amount of time to play, many women are still unwilling to identify as ‘gamers’ and claim membership within the larger gaming community. Gendered marketing practices in the industry may play a role by impacting the consumption preferences of women, which in turn impacts the way...

Bruised But Not Broken: Exploring Levels of Education Violence in Higher Education

Christopher Mathis
Scholars in higher education often placate the idea of race and racism. Harper (2012) notes that when scholars in the field dealt with racial disparities in higher education in several contexts, they overwhelmingly attributed such difference to all other factors except racism. Put simply, scholars in the field often overlook how and when race and racism appear in higher education. Thus, a growing number of scholars in higher education (Chesler, Lewis, & Crawfoot, 2005; Harper,...
