The certainty that one feels following a decision increases decision-making efficiency, but can also result in decreased decision accuracy. In the current study, a neuropsychological approach was used to examine the impact of damage to the ventromedial prefrontal cortex (vmPFC) on core psychological processes promoting decision certainty: selective exposure, overconfidence, and decisiveness. Gi...

Overconfidence has long been considered a cause of war. Like other decision-making biases, overconfidence seems detrimental because it increases the frequency and costs of fighting. However, evolutionary biologists have proposed that overconfidence may also confer adaptive advantages: increasing ambition, resolve, persistence, bluffing opponents, and winning net payoffs from risky opportunities...

The present study investigates the relationship between management characteristics (managerial entrenchment, CEO narcissism, overconfidence, board effort, real and accrual-based earnings management) audit report readability of listed firms. In other words, this paper seeks to answer question “whether can have a favourable effect on or not.” multivariate regression model is used for study. Resea...

Purpose The purpose of this study is to examine the moderating role characteristics chief executive officer (CEO) on association between CEO power and corporate social responsibility (CSR) performance. Design/methodology/approach This paper conducts multiple regression analyses empirically test proposed hypotheses based a sample US-based publicly held companies. period extends from 2000 2018. F...

We examined the relationships among CEO perceived charisma, CEO compensation packages, and firm performance in a sample of Fortune 500 companies over a 10-year period. CEO charisma ratings obtained from company CFOs and VPs for HRM were directly related to total CEO pay but not to any firm performance measures. CEO perceived charisma also was related to shareholder value, under highly uncertain...

We identify several theories that each suggest a link between CEO turnover and changes among a firm’s top non-CEO managers. We then assess these links empirically using two panel data sets. We present five main findings. First, we find that CEO and non-CEO turnover are positively associated. Second, we do not find that this association is stronger when firm performance is poor. Third, this asso...

Background: An essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. Objective: Cumin (Cuminum cyminum L.) Essential Oil (CEO) was analyzed to determine oil component. Antifungal effect of CEO was determined by in vitro technique. In second stage, effect of different concentrations of CEO by PDM on postharvest life of strawberry (Fr...

Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
