In this paper, we introduce a framework for providing incentives for honest participation in global-scale distributed trust management infrastructures. Our approach is twofold: (1) we provide rewards for peers that advertise their experiences to others, and (2) impose the credible threat of halting the rewards, for a substantial amount of time, for participants who consistently provide suspicio...

The effects of lesions, receptor blocking, electrical self-stimulation, and drugs of abuse suggest that midbrain dopamine systems are involved in processing reward information and learning approach behavior. Most dopamine neurons show phasic activations after primary liquid and food rewards and conditioned, reward-predicting visual and auditory stimuli. They show biphasic, activation-depression...

Humans generally prefer social over nonsocial stimuli from an early age. Reduced preference for social rewards has been observed in individuals with autism spectrum conditions (ASC). This preference has typically been noted in separate tasks that measure orienting toward and engaging with social stimuli. In this experiment, we used two eye-tracking tasks to index both of these aspects of social...

Background: Nursing is emotional work and learning how to manage their emotions is a valuable part of nurse education. As the workforce becomes increasingly mobile nurses will care for people from diverse cultures and backgrounds. The development of cultural competence and a global mind-set is therefore a valuable asset and engagement in study abroad through overseas clinical placement can help...

This research examines the moderating influence of the extent to which a brand's social initiatives are integrated into its competitive positioning (i.e., a CSR positioning) on consumer reactions to CSR. We find that positive CSR beliefs held by consumers are associated not only with greater purchase likelihood but also with longer-term loyalty and advocacy behaviors. More importantly, we find ...

Highly accurate sensor measurements are crucial in order for power plants to effectively operate, as well as to predict and subsequently prevent any potentially catastrophic failures. As the cost of sensors decreases while their power increases, distributed sensor networks become a more attractive option for implementation in power plants. In this work, we investigate the use of a distributed s...

Retention in the IT profession is critical for organizations to stay competitive and operate reliably in the dynamic business environment. Most organizations rely on compensation and rewards as primary tools to enhance retention of employees. In this quantitative survey-based study conducted at a large global bank, we analyze the perceptions of 575 information technology (IT) software professio...

Clark AM. Reward processing: a global brain phenomenon? J Neurophysiol 109: 1–4, 2013. First published July 18, 2012; doi:10.1152/jn.00070.2012.—Rewards and punishments (reinforcement) powerfully shape behavior. Accordingly, their neuronal representation is of significant interest, both for understanding normal brain-behavior relationships and the pathophysiology of disorders such as depression...

In this paper, we introduce a framework for providing incentives for honest participation in global-scale distributed trust management infrastructures. Our system can improve the quality of information supplied by these systems by reducing free-riding and encouraging honesty. Our approach is twofold: (1) we provide rewards for participants that advertise their experiences to others, and (2) imp...
