Given the dramatic behavioral effects of winning and losing contests, and pronounced changes in stress and sex steroid hormones post-fight, it is reasonable to suppose that these hormones also dictate future behavior. We sampled water-borne cortisol, testosterone (T), and 11-ketotestosterone (KT) before and after contests in the mangrove killifish, Kryptolebias marmoratus, to determine how endo...

Problem, research strategy, and findings Disaster assistance in the United States has faced criticism for widening unequal impacts of disasters, but little is known about whether how this phenomenon applies to businesses. Small businesses make up most States, they are particularly vulnerable hazards given their relative lack capital. Because recovery primarily loan based, capital can create con...

The binding of [H]SCH 23390 has been studied in various brain regions of male mice with the experience of repeated victory (winners) or defeat (losers) gained over 10 (T10) and 20 (T20) days of daily agonistic confrontations. In the frontal cortex, Bmax of [H]SCH 23390 binding sites was found to be increased in T10 losers and decreased in T20 losers when compared to the control mice. In the str...

The binding of [3H]SCH 23390 has been studied in various brain regions of male mice with the experience of repeated victory (winners) or defeat (losers) gained over 10 (T10) and 20 (T20) days of daily agonistic confrontations. In the frontal cortex, B(max) of [3H]SCH 23390 binding sites was found to be increased in T10 losers and decreased in T20 losers when compared to the control mice. In the...

We analyze the effect of innovation on asset prices in a tractable, general equilibrium framework with heterogeneous households and firms. Innovation has a heterogenous impact on households and firms. Technological improvements embodied in new capital benefit workers, while displacing existing firms and their shareholders. This displacement process is uneven: newer generations of shareholders b...

Politicians adopt a variety of linguistic strategies in their speeches to connect with their audience. To name one, appraisal, as a system of interpersonal meaning, is concerned with evaluation where resources are used for negotiating social relationships. Despite their significance in shaping texts, there have hardly been any extensive inventories of appraisal tools contrasting electoral speec...

BACKGROUND Alpha-synuclein (α-Syn) is a small neuronal protein that has been found to be expressed throughout the brain. It has been shown that α-Syn regulates the homeostasis of monoamine neurotransmitters and is involved in various degenerative and affective disorders. There is indication that α-Syn may regulate expression of the brain-derived neurotropic factor (BDNF) which plays an importan...

When designing a contest to motivate effort by salespeople, service employees, franchisees or product development teams, one of the key questions faced by managers is: What should be the optimal proportion of winners and losers? Prevailing marketing theory predicts that the proportion of winners in a contest should always be lower than the proportion of losers. Not only has this theory not been...
