The arc costs are assumed to be online parameters of the network and decisions should be made while the costs of arcs are not known. The policies determine the permitted nodes and arcs to traverse and they are generally defined according to the departure nodes of the current policy nodes. In on-line created tours arc costs are not available for decision makers. The on-line traversed nodes are f...

We acknowledge the fact that situational details can have impact on the trust that a Trustor assigns to some Trustee. Motivated by that, we discuss and formalize functions for determining context-aware trust. A system implementing such functions takes into account the Trustee’s profile realized by what we call quality attributes. Furthermore, the system is aware of some context attributes chara...

Many species of large wildlife have declined drastically worldwide. These reductions often lead to profound shifts in the ecology of entire communities and ecosystems. However, the effects of these large-wildlife declines on other taxa likely hinge upon both underlying abiotic properties of these systems and on the types of secondary anthropogenic changes associated with wildlife loss, making i...

INTRODUCTION This paper argues that particular experiences in the workplace are more important than others and can lead to transformational learning. This may enable practitioners to cross 'vocational thresholds' to new ways of being. AIM A notion of 'vocational thresholds' is developed, aiming to help build an understanding of the most powerful learning experiences of general practitioners (GP...

I extended recruitment research by sampling from the applicant population to investigate factors related to a firm’s attractiveness as an employer on college campuses. Specifically, I surveyed potential applicants at nine different universities and university personnel (faculty and placement staff) at eight of those universities to investigate relationships of recruitment activities, organizati...

This paper proposes a framework for the development of models for the assessment of research activities and their impacts. It distinguishes three dimensions: theory, methodology and data, each of which is further characterized by three main building blocks: education, research and innovation (theory); efficiency, effectiveness and impact (methodology); and availability, interoperability and “un...

OBJECTIVE To compare awareness about concept of social wellness in male and female first year medical students. METHODS It was a cross sectional, questionnaire based study conducted from February till December 2010.

In a series of studies, it is demonstrated that different types of self-affirmation procedures produce different effects. Affirming personally important values (value affirmation) increases self-clarity but not self-esteem. Affirming positive qualities of the self (attribute affirmation) increases self-esteem but not self-clarity (Study 1). As a consequence, attribute affirmation (which increas...

This paper elaborates on ontology-based end-user visual query formulation, particularly for users who otherwise cannot/do not desire to use formal textual query languages to retrieve data due to the lack of technical knowledge and skills. Then, it provides a set of quality attributes and features, primarily elicited via a series of industrial enduser workshops and user studies carried out in th...
