Juvenile salmonid fish readily form dominance hierarchies when faced with limited resources. While these social interactions may result in profound behavioural and physiological stress, it is unknown if this social stress is evident at the level of the cellular stress response--specifically, the induction of stress or heat shock proteins (Hsps). Thus, the goal of our study was to determine if H...

Many mammalian species form dominance hierarchies, but it remains unknown whether differences in social status correspond to structural differences in the brain. Stressful experiences may arise naturally during the establishment of dominance, and stress has been linked to adult neurogenesis in the hippocampus. To determine whether position in a dominance hierarchy leads to changes in adult neur...

BACKGROUND Studies that have examined social determinants of health have made their investigations on the population, but none have reviewed them from the perspective of particular social hierarchies. AIM The study examined the factors determining the self-reported health of men of different socioeconomic status, by using models derived through econometric analyses. MATERIALS #ENTITYSTARTX00...

Annotea is a framework that supports Semantic Web based collaboration and authoring via Annotea objects, such as social annotations, bookmarks, and topics. Social bookmarks and topics can be used for semantic authoring in many levels. They let ordinary users tag interesting Web documents with their own personal concepts (folksonomies). These concepts can be simple or form hierarchies, and they ...

We tested 15-month-olds' capacity to represent social-dominance hierarchies with more than two agents. Our results showed that infants found it harder to memorize dominance relations that were presented in an order that hindered the incremental formation of a single structure (Study 1). These results suggest that infants attempt to build structures incrementally, relation by relation, thereby s...

This paper takes game-theoretic and latent variable approaches to modeling international social hierarchies and their effect on conflict among states. I argue that, within these hierarchies, states adopts one of two roles—a dominant or a subordinate. Each resulting (dyadic) dominant–subordinate relationship is a social (informal) contract, in which the subordinate concedes some autonomy in exch...
