New Drone Rules, London Theater, Retro VR, Therapy Dropouts

Guest: Tim McLain, Ph.D., Director of the Center for Unmanned Aircraft Systems and Professor of Mechanical Engineering at BYU Federal regulators this week announced plans to create a national registry of recreational drones. The move to make hobby drone-users register their vehicles is fueled by a rise in sightings and "close calls" between drones and airplanes, according to the Federal Aviation Administration. Small, easy-to-fly drones have become hugely popular. This year about 700,000 are expected to be sold in America - that's up more than 60 percent over last year's figures.

Guest: Tim Slover, Ph.D., and Jane England of the University of Utah's Department of Theatre Everybody knows when you visit New York, you need to see a play - preferably a big, shiny musical on Broadway. But this next guests says, if theater is your thing, New York is not your best bet. Hop the pond to London, and not just because that's where Sherlock star Benedict Cumberbatch is onstage doing Hamlet in what one review called "an extravagantly royal affair."

Guest: Evan Suma, Ph.D., Virtual Reality Researcher in the Mixed Reality Lab at the USC Institute for Creative Technologies Retro video games like Pac-Man and Donkey Kong are cool again with teenagers. The pixelated graphics are fun in a vintage-chic way that's so, so vastly different from the movie-like, immersive images of today's video games. But you know what the old school and the new school video games all have in common? Hand-held controllers with joysticks and buttons. That's weird, isn't it? That visually, things would have advanced so far, but you're still controlling the game in basically the same way? Maybe not for long, though, if Evan Suma has his way.

Guest: Grant Madsen, Ph.D., BYU History Professor Today’s conversation will cover the complex history and lasting impact of the Vietnam War.

Guest: Guest: Brandon Purdie, Provo Film Society; Greg Whiteley, Documentary Director, "New York Doll" and "Mitt" "New York Doll" is the story of a wild life that turns quiet, making it a unique story with a twist at the end that even the filmmakers couldn't have predicted. There is a need for theaters who will show independently made movies like "New York Doll."

Guest: Partha Krishnamurthy, Ph.D., Professor of Marketing at the University of Houston and Director of the Institute for Health Care Marketing Therapists have a drop out problem. Somewhere in the range of 50 percent of patients in psychotherapy stop showing up for treatment before the prescribed number of sessions is through. They just drop out. Why they drop out is something of a mystery to psychotherapists. But community mental health clinics consider it a pressing problem.
