The Reference Point Method (RPM) is an interactive technique formalizing the so-called quasi-satisficing approach to multiple criteria optimization. The DM’s preferences are there specified in terms of reference (target) levels for several criteria. The reference levels are further used to build the scalarizing achievement function which generates an efficient solution when optimized. Typical R...

The aim of the present study was to examine (a) if athletes’ moral judgment is affected by sport type, the level of competition – in terms of the league in which one competes – and regular playing position, and (b) possible relations between moral judgment and the overall years of athletic experience, self-perception of sport ability, and achievement goal orientations. The sample comprised 170 ...

While many studies confirm that positive emotions, including enjoyment, lead to better student achievement, less empirical evidence exists about possible mediator variables that link achievement to enjoyment. It is proposed that achievement and enjoyment form a circular dependency; enjoyment in learning leads to higher achievement but a degree of achievement is required to enjoy learning. This ...

We experimentally demonstrate a chiral metamaterial exhibiting negative refractive index at terahertz frequencies. The presence of strong chirality in the terahertz metamaterial lifts the degeneracy for the two circularly polarized waves and allows for the achievement of negative refractive index without requiring simultaneously negative permittivity and negative permeability. The realization o...

This article examines the classroom learning environment in relation to achievement goal theory of motivation. Classroom structures are described in terms of how they make different types of achievement goals salient and as a consequence elicit qualitatively different patterns of motivation. Task, evaluation and recognition, and authority dimensions of classrooms are presented as examples of st...

Agent-oriented methodologies frequently make use of terms such as goal and task but do so in an inconsistent manner. We seek to rationalize the use of these terms by undertaking an etymological and metamodel-based analysis of a significant number of these AO methodologies and recommend that the word task be avoided; instead, the word action could be usefully employed to describe the work done t...

This study assessed how rewards impacted intrinsic motivation when students were rewarded for achievement while learning an activity, for performing at a specific level on a test, or for both. Undergraduate university students engaged in a problem-solving activity. The design was a 2 2 factorial with 2 levels of reward in a learning phase (reward for achievement, no reward) and 2 levels of rewa...
