Competition-related factors directly influence preferences for facial cues of dominance in allies

Alliance formation is a critical dimension of social intelligence in political, social and biological systems. As some allies may provide greater ‘leverage’ than others during social conflict, the cognitive architecture that supports alliance formation in humans may be shaped by recent experience, for example in light of the outcomes of violent or non-violent forms intrasexual competition. Here we used experimental priming techniques to explore this issue. Consistent with our predictions, while men’s preference for dominant allies strengthened following losses (compared to victories) in violent intrasexual contests, women’s preferences for dominant allies weakened following losses (compared to victories) in violent intrasexual contests. Our findings suggest that while men may prefer dominant (i.e. masculine) allies following losses in violent confrontation in order to facilitate successful resource competition, women may ‘tend and befriend’ following this scenario and seek support from prosocial (i.e. feminine) allies and/or avoid the potential costs of dominant allies as long-term social partners. Moreover, they demonstrate facultative responses to signals related to dominance in allies, which may shape sex differences in sociality in light of recent experience and suggest that intrasexual selection has shaped social intelligence in humans.

Regionalism as trading blocks, a comparative analysis of the legal structure of the EC and NAFTA within the context of the WTO

Geography has almost become obsolete. The world’s goods and services can now be accessed instantaneously by electronic commerce. Small and medium sized countries have felt the cold winds of change blowing, and have adopted the “safety in numbers” philosophy. Regional organisations throughout the world have sprung up, with their original raison d'être the encouragement and development of regional trading blocks. Two of the most developed regional groupings are the EU/EC and NAFTA. These two organisations represent two quite different philosophies of regional trade groupings, with contrasting legal structures. The advent of Trade Globalisation, with the founding of the WTO has brought these two approaches into confrontation, as each side of the Atlantic Ocean tries to influence the development on the naissant WTO. This paper examines the two contrasting legal structures, and the conflict on an inter regional level that they are engendering.
