Since the events of the 2011 Arab Spring were set in motion, a debate has continued over how powerful a role the Internet itself can play in bringing about tangible social change. Evidence may continue to emerge that challenges any current theory. But in any case, new intellectual frameworks are required to analyze this question and guide further study.

The economic turmoil of 2007-2009 adversely impacted household earnings across America, but a 2011 research study details the extent to which significant declines in household wealth were concentrated in lower-income and minority populations and those whose wealth was primarily derived from their homes.

What sorts of correlations can be drawn between online interactions and face-to-face friendships?

The number of college courses available online has steadily grown since the advent of “Web 2.0” interactive technologies in the early 2000s, and in the wake of the economic crisis of 2008. Nearly half (46%) of all college students graduating in 2001 or later have taken at least one online course, and the number of online courses is expected to continue to grow over the next decade.

Speaking with a family member or friend triggers hormonal changes in the body that reduce stress, calm nerves and promote social bonding. It is not clear, however, which elements of a verbal exchange — grammar, syntax, tone and/or word choice — are responsible for triggering these neurochemical responses.

Approximately 27% of military personnel sought medical assistance for symptoms of post-traumatic stress disorder through a Veterans Affairs (VA) health facility between  2002 and 2010, according to a 2011 report by the  Congressional Research Service (PDF). Common PTSD treatments include both medication and cognitive-behavioral therapy through hospital stays and outpatient service.
