Researchers at Queens University have found a strong association between computer and Internet use in adolescents and engagement in multiple-risk behaviours (MRB), including illicit drug use, drunkenness and unprotected sex.

“This research is based on social cognitive theory, which suggests that seeing people engaged in a behaviour is a way of learning that behaviour,” explains lead researcher Valerie Carson, a doctoral candidate in School of Kinesiology and Health Studies. “Since adolescents are exposed to considerable screen time—over 4.5 hours on average each day—they’re constantly seeing images of behaviours they can then potentially adopt.”

The researchers found that high computer use was associated with approximately 50 per cent increased engagement with a cluster of six MRB, including smoking, drunkenness, non-use of seatbelts, cannabis and illicit drug use, and unprotected sex. High television use was also associated with a modestly increased engagement in these MRB. [continue reading…]

“The main significance of the wedding might be the international audience. For Britain, it’s very important to retain its global brand. We don’t export a lot in England, but weddings seem to be some of our best products.

“In another context, this is a very important event for the British monarchy – when compared to the wedding of Charles and Diana. The way Charles’ marriage ended was a disaster. With William and Kate, it seems to be the Monarchy’s way to patch a toxic event. [continue reading…]
