Ropalidia marginata is a primitively eusocial, polistine wasp widely distributed in peninsular India. In spite of its primitively eusocial status, queens of R. marginata are surprisingly docile and behaviourally non-dominant (except during the first week or so of their careers as queens). Yet they successfully maintain reproductive monopoly throughout their careers, probably through the use of ...

The authors present a model that explains how subordinates perceive the power of their supervisors and the causal mechanisms by which these perceptions translate into subordinate outcomes. Drawing on identity and resource-dependence theories, the authors propose that supervisors have power over their subordinates when they control resources needed for the subordinates' enactment and maintenance...

OBJECTIVES It is controversial whether a semantic processing bias for strong associates is present in schizophrenia, and unknown whether the language abnormalities observed in schizophrenia can be attributed to dysfunctions early or late in cognitive processing. Combined behavioral and event-related potential (ERP) data can indicate the nature and timing of such abnormalities. METHODS Sensibi...

Evidence is contradictory regarding the effects of natural or surgical menopause on "female protection" against coronary artery atherosclerosis. We evaluated atherosclerosis, plasma lipids, blood pressure, and carbohydrate tolerance in 21 ovariectomized and 23 intact female cynomolgus macaques fed a moderately atherogenic diet for 30 months. We also evaluated the influence of social dominance s...

In cooperative animal societies, dominant females typically show higher breeding success than subordinates, and are commonly believed to control the extent of reproductive sharing. However, studies of social insect societies reveal that subordinates too can interfere with the breeding attempts of others, with important implications for the distribution of fitness within colonies. Here, we show ...

Our previous work showed a semantic bias in interpreting ambiguous words in schizophrenia, with disproportionate misinterpretation of subordinate meanings (toast at a wedding). We proposed pre-selection in schizophrenia of dominant-meaning networks at points of lexical ambiguity, thereby misleading thought. This selection bias may be due to semantic memory hyper-priming causing strong associate...

Two eye-tracking during listening experiments found frequency and context effects on fixation probability of pictures representing multiple meanings of homophones. Participants heard either an imperative sentence instructing them to look at a homophone referent (Experiment 1) or a declarative sentence that was either neutral or biased towards the homophone‘s subordinate meaning (Experiment 2). ...

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...
