Head Trauma and Learning
November 23, 2012
Researchers at my alma mater have joined their voices to the growing chorus of concerns about the effects of repeated blows to the head.
A study of the cognitive effects of head impacts on members of Dartmouth College football, hockey, track, crew and Nordic ski teams compared before and after season results on learning and memory skills. Participating athletes also came from Brown and Virginia Tech.
-
22 percent of athletes in contact sports had lower results on learning and memory skills tests after their season.
-
Only 4 percent of athletes in non-contact sports posted lower test results.
The researchers caution that it is unknown at this point how long these negative effects may last, but they also note there is some correlation between test results and how hard the athletes were hitting heads.
This adds to the mounting evidence that rules writers, program sponsors, coaches and officials must look for and implement a variety of measures to reduce the frequency and severity of head impacts in both practice and competition in all sports.
Lost in Time

So, North Korea is establishing its own unique time zone – “Pyongyang time” – named after the nation’s capital city. North Korea will fall 30 minutes behind Japan whose time zone was imposed on the entire Korean peninsula more than 100 years ago.
Actually, North Korea is more than 30 years behind Japan in almost every aspect of civilized life.
This time zone adjustment gesture is of little practical significance because North Koreans have been closed off from global interaction by the impositions of their brutal dictators since the end of World War II. It’s symbolism befitting the backward nation’s isolationism.
The negative effects of this isolationism upon the nation are visible across the Demilitarized Zone from South Korea. Behind visitors to the DMZ is the vibrant mega-city of Seoul, South Korea. Across the river is a bleak, barren landscape with no sign of life. No people, no agriculture. Just a few buildings, without inhabitants. Built only for show.
There are many lessons to be learned from this contrast, on many levels. Of course, we see how people thrive more in an atmosphere of freedom than totalitarianism. We see the benefits of engagement over isolationism. We see that symbols without substance are meaningless.
Lessons for nations, to be sure. But reminders for enterprises of all kinds, including ours.
And a note to North Korea ... Newfoundland Island has had its own time zone for many years. It’s 30 minutes ahead of the rest of North America, and a century ahead of North Korea.
