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...

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 ...

This document is complementary to our ICIP 2015 paper titled " A Fast Method for Inferring High-Quality Simply-Connected Superpixels ". It contains additional examples for a visual comparison between the different methods.

A new implementation for minimally redundant radix-4 SRT division with the recurrence in the signed-digit format is introduced. The implementation is developed based on the comparison multiples idea. In the proposed approach, the quotient digit’s magnitude is calculated by comparing the truncated partial remainder with two limited precision multiples of the divisor. The sign is determined by in...

Re-representation is a mechanism for aligning non-identical structurally corresponding predicates during comparison. Re-representation is therefore a shift in the encoding of a stimulus from an initial set of elements to an altered set. For example, when comparing two analogous sentences, different verbs could be re-represented to allow a match – thereby altering construal. Re-representation is...

We apply the method of comparison equations to study cosmological perturbations during inflation, obtaining the full power spectra of scalar and tensor perturbations to first and to second order in the slow-roll parameters. We compare our results with those derived by means of other methods, in particular the Green’s function method and the improved WKB approximation, and find agreement for the...

Agreement between two methods of clinical measurement can be quantified using the differences between observations made using the two methods on the same subjects. The 95% limits of agreement, estimated by mean difference +/- 1.96 standard deviation of the differences, provide an interval within which 95% of differences between measurements by the two methods are expected to lie. We describe ho...

Determining the similarity of document images is an important first step for several document retrieval tasks, such as document classification, information extraction, and retrieval based on visual similarity. In this paper, we propose a method to describe and compare the content and layout of a document given only an image of the document. A tree structure is used to capture the hierarchical s...
