Results indicated changes in passing in modem football tactics. Actual playing time is represented as Net Playtime in this study. Pass Appearance Time is calculated by Net Playtime divided by passes Attempted. Pass Appearance Time of each team for the all Group stage games was calculated and compared with World cup 2010. No difference was revealed in the 2014 data between teams that did and did not qualify, though the 2010 data revealed differences. World cup 2010 data suggested that increasing passes attempts and lessening Pass Appearance Time were effective in qualifying for the 2rid stage. World cup 2014 data, however, suggested that diversity of tactics was important.展开更多

For this kind of games, the cooperation among unions and within each union will be the convex sets, i.e., the feasible subsets of the coalition structure and that of each union belong to a convex geometry, respectively. The explicit form of the generalized Owen value for this kind of games is given, which can be seen as an extension of the Owen value.
