International approaches to whole-of-school physical activity promotion

after-school settings

McMullen J, Ni D, Tammelin T, Pogorzelska M.
GSID: LY9F0-mqI4MJ
J McMullen, D Ni Chroinin, T Tammelin, M Pogorzelska… - Quest, 2015 - Taylor & Francis

… As a result, many countries have designed and implemented whole-of-school physical activity initiatives that seek to increase physical activity opportunities that are available to school-aged children before, during, and after school. Considering the comprehensive school …

Schizophrenia spectrum disorders are associated with high morbidity and mortality in somatic diseases. The risk factors of this excess mortality include, e.g., obesity, dietary factors, and physical inactivity, especially after the onset of psychosis, but there are limited early...

Computer science. Heads-up limit hold'em poker is solved.

Science (New York, N.Y.)

Bowling M, Burch N, Johanson M, Tammelin O.
PMID: 25574016
Science. 2015 Jan 09;347(6218):145-9. doi: 10.1126/science.1259433.

Poker is a family of games that exhibit imperfect information, where players do not have full knowledge of past events. Whereas many perfect-information games have been solved (e.g., Connect Four and checkers), no nontrivial imperfect-information game played competitively by...
