In this document, we describe a light-weighted ontology mediation method that allows users to send semantic queries to distant data repositories to browse for learning object metadata. In a collaborative E-learning community, member data repositories might use different ontologies to control a set of vocabularies describing topics in learning resources. This could hinder the search of learning ...

Intrinsic motivation has been reported to be one of the strongest determinants of exercise adherence. The role of competition in exergames was studied to determine the ways to increase intrinsic motivation. We tested the competitive exercise setting as a contextual factor, and competitiveness as individual characteristic, to investigate their effect on intrinsic motivation using psychological, ...

This paper ANDROMEDA, an astronomical data mediation system that enables transparent access to astronomical data servers. Transparent access is achieved by a global view that expresses requirements of community of users (e.g., astronomers) and data integration mechanisms adapted to astronomical data characteristics. Instead of providing an ad hoc mediator, ANDROMEDA can be configured for giving...

Relationship marketing—establishing, developing, and maintaining successful relational exchanges—constitutes a major shift in marketing theory and practice. After conceptualizing relationship marketing and discussing its ten forms, the authors (1) theorize that successful relationship marketing requires relationship commitment and tnjst, (2) model relationship commitment and trust as key mediat...

This paper will explore if and how psychological strain plays a mediator role between the learning climate and job performance in a group of health workers. Although the relationship between learning climate and job performance has already been explored in the international literature, the role of psychological strain, which may hamper or deepen this relationship, has yet to be investigated. Th...

Narrative Mediation is a new approach to mediation that was spurned by Narrative Family Therapy, developed in the mid-1980s by Michael White and David Epston, in Australia. It came out of their interest in post-modernism and social constructionism, in examining the making of meaning through the filter of language and the subjective interpretation of “facts”. While Narrative Therapy has become r...

Recent simulation studies have pointed to the higher power of the test for the mediated effect vs. the test for the total effect, even in the presence of a direct effect. This has motivated applied researchers to investigate mediation in settings where there is no evidence of a total effect. In this paper we provide analytical insight into the circumstances under which higher power of the test ...

The purpose of the present study is to empirically investigate what drives the establishment of security knowledge sharing in organisations. Based on a theoretical understanding a research model was developed and tested by collecting and analysing data from 62 security executives from a diverse set of organisations located in different geographic regions in the world. The empirical tests of a s...
