Social Capability Deficits and Productivity Behaviour of African Entrepreneurs:
Despite attempts to induce regional competitiveness in industrial manufactures, poor productivity performances continue to plague the ability of African entrepreneurs to compete successfully in international markets. While many plausible explanations can be put forward to explain this failing, we argue in this paper that an analysis of the social and institutional context within which these ent...
متن کاملSocial life, evolution of intelligence, behaviour and human brain size
Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...

Social opportunity causes rapid transcriptional changes in the social behaviour network of the brain in an African cichlid fish.
Animals constantly integrate external stimuli with their own internal physiological state to make appropriate behavioural decisions. Little is known, however, about where in the brain the salience of these signals is evaluated, or which neural and transcriptional mechanisms link this integration to adaptive behaviours. We used an African cichlid fish Astatotilapia burtoni to test the hypothesis...
متن کاملSocial and spatial structure and range use by Kaimanawa wild horses (Equus caballus: Equidae)
We measured horse density, social structure, habitat use, home ranges and altitudinal micro-climates in the south-western Kaimanawa ranges east of Waiouru, New Zealand. Horse density in the Auahitotara ecological sector averaged 3.6 horses.km and ranged from 0.9 to 5.2 horses.km within different zones. The population’s social structure was like that of other feral horse populations with an even...
