In this paper, several state-of-the-art noise reduction algorithms are ranked using both subjective evaluation and twenty objective measures proposed in literature. The goal of the study was to find the objective quality measure that best relates to the subjective assessment for noise reduction. A measurement setup comprising a simulation of a TV-transmission channel has been used to provide a ...

A considerable body of accounting research has analysed the effectiveness of subjective performance assessment to compensate for the shortcomings of objective performance measures. The present paper adds a further perspective to this research by analysing the interaction between autonomous motivation and performance evaluation systems that either contain only objective measures or also apply su...

Infection control studies often rely on infection endpoints to determine whether interventions are effective. However, many infection outcomes, including those defined by standardized surveillance criteria, involve some subjective judgment for determination. Studies that use unblinded ascertainment of subjective infection endpoints are at risk of assessment bias. Unfortunately, infection contro...

This article adopts a critical sociological perspective to examine the expectations surrounding the uses of social networking sites (SNSs) articulated in the domain of clinical literature. This emerging body of articles and commentaries responds to the recent significant growth in SNS use, and constitutes a venue in which the meanings of SNSs and their relation to health are negotiated. Our ana...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...
