Social Comparison is important as it can be either encouraging or discouraging for the person who makes it. Although studies concerning social comparison in the classroom context abound, few deal with the relationship between the role of social comparison orientation and tendencies in academic achievement in a competition based educational context. Adopting a non- experimental ex-post facto des...

A review is given of the first workshop dedicated to the detailed comparison of various approaches to the calculation of spectral line shapes in plasmas. A standardized set of case problems was specified in advance, together with the prescribed atomic data and assumptions to be used. In this brief review, motivations for the case problems chosen are outlined, followed by a discussion of selecte...

Data involving spatial and/or temporal attributes are often represented at different levels of granularity in different source schemata. In this work, a model of such multigranular data is developed, which supports not only the usual order structure on granules, but also lattice-like join and disjointness operators for relating such granules in much more complex ways. In addition, a model for m...

When data from several source schemata are to be integrated, it is essential that the resulting data in the global schema be consistent. This problem has been studied extensively for the monogranular case, in which all domains are flat. However, data involving spatial and/or temporal attributes are often represented at different levels of granularity in different source schemata. In this work, ...

Structure-mapping theory asserts that analogical comparison involves a process of structural alignment based on finding common relational structure (Gentner, 1983). During this process, correspondences are established between the aligned components of the analogs—both relations and objects. In the present experiment, we show that this alignment process is strikingly more efficient when the "cor...

Kittur et al. (2004, 2006) and Jung and Hummel (2011, 2014) showed that people have great difficulty learning relation-based categories with a probabilistic (i.e., family resemblance) structure, in which no single relation is shared by all members of a category. Yet acquisition of such categories is not strictly impossible: in all these studies, roughly half the participants eventually learned ...
