When should you pull a goalie?
It’s a coaching strategy that hasn’t worked particularly well during the 2010 Stanley Cup playoffs. Why? Do the math - Tim Swartz has. Using simulation algorithms, he and fellow researchers found that goalies aren’t being pulled soon enough. Swartz, a professor in SFU’s department of statistics and actuarial science, is part of a research team studying the effectiveness of the pull-the-goalie strategy, using data from the NHL’s regular 2007-2008 regular season. The researchers found coaches need to be more aggressive with the tactic in order to increase the probability of winning. The research will be published this summer in the journal American Statistician. The study can be found on Swartz’s website at http://www.stat.sfu.ca/~tim/

Sink-holes could swallow B.C. homes
While rescuers are desperately searching a kilometer-long and half-a-kilometre-wide sinkhole that has swallowed up a home and possibly its residents in Quebec, geologists are assessing the stability of nearby evacuated homes. SFU earth scientist Brent Ward, an expert in soil erosion, can explain why areas of B.C., like Kitimat and Terrace, have been swallowed up in landslides like the recent one in Quebec. Ward cautions these areas are prone to experiencing such catastrophes.
