O Momento Imperial

Após os atentados terroristas de 11 de Setembro de 2001, a política externa norte-americana sofreu uma revisão significativa na definição de prioridades, gerando-se, ao mesmo tempo, uma forte controvérsia quanto ao papel dos EUA no mundo e à sua inserção no panorama geo-estratégico internacional. No cerne dessa controvérsia três grandes temas têm estado presentes: a questão da hegemonia; do unilateralismo vs . multilateralismo; e o da natureza imperial – ou não – da política externa norte-americana.

Ball Recovery in the Handball Tournament of the 2008 Beijing Olympic Games: Sequential Analysis of Positional Play as Used by the Spanish Team’s Defence

In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.
