Trust Establishment is one of the significant resources to enhance the scalability and reliability of resources in the cloud environment. To establish a novel trust model on SaaS (Software as a Service) cloud resources and to optimize the resource utilization of multiple user requests, an integrated software trust estimator with multi-user resource competence (IST-MRC) optimization mechanism is...

The purpose of this study was to explore the effectiveness of a new feedback mechanism within an intelligent tutoring system called AutoTutor LITE. Participants were randomly assigned to one of three feedback manipulation conditions within the context of complex scientific material: 1) learners’ characteristics curves; 2) random; 3) no feedback. Results revealed that the participants receiving ...

Reputation systems that rely on voluntary feedback from traders are important in creating and sustaining trust in markets. Reporting feedback, however, is often costly for the reporter and feedback is a public good. We combine theory with a laboratory experiment to study the effect of a novel seller precommitment mechanism on promoting feedback and market efficiency. Specifically, our precommit...

Mineral paragenesis of rodingitized basic rocks of Iranian ophiolites are presented and metasomatic reactions between Ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. It is concluded that Ca+2 rich aqueous fluid in equilibrium with serpentinite has high Ca+2 chem...

This article proposes a framework of personalized feedback mechanism to help multiple inconsistent experts reach consensus in group decision making by allowing select different parameters according individual degree. The general harmony degree (GHD) is defined determine the before/after difference between original and revised opinions. It proved that GHD index monotonically decreasing with resp...
