Services such as Wikipedia, Flickr, Technorati, Yahoo!, YouTube, del.icio.us appear in many web applications, employ the folksonomy as their social tagging mechanism, where users assign tags to resources and share it with each other within their community. As the number of the folksonomy-based systems is increased, some proper data mining approaches to folksonomies are necessary to better under...

Triadic distance models can be used to analyse proximity data defined on triples of objects. Three-way symmetry is a common assumption for triadic distance models. In the present study three-way symmetry is not assumed. Triadic distance models are presented for the analysis of asymmetric three-way proximity data that result in a simultaneous representation of symmetry and asymmetry in a low-dim...

Triadic distances t defined as functions of the Euclidean (dyadic) distances a1, a2, a3 between three points are studied. Special attention is paid to the contours of all points giving the same value of t when a3 is kept constant . These isocontours allow some general comments to be made about the suitability, or not, for practical investigations of certain definitions of triadic distance. We a...

In this paper, we examine the evolution of triadic motifs in a large-scale human communication network. We consider extant models of triadic evolution, emphasizing vertex-, dyadic-, triadicand higher-level processes in order to generate testable hypotheses of the predictors of both over time triangle survival and triangle emergence from lower-order motifs. We find that the stability and formati...

The performance of manufacturing as the prominent sector decreased because COVID-19 pandemic. Nevertheless, it could bounce back its quickly right after. question remains whether new ways working take part in this agile behavior employees adapting to such a situation. Even so, what kind be implemented since has specific processing system from input output? Implementing practices varies primary ...

We define a closure operation for ideals in a commutative ring which has all the good properties of solid closure (at least in the case of equal characteristic) but such that also every ideal in a regular ring is closed. This gives in particular a kind of tight closure theory in characteristic zero without referring to positive characteristic.

The purpose of this study was to examine the reverse pathway dynamics between teachers’ self-efficacy and job satisfaction from a cross-country perspective. By recognizing sparseness empirical studies on reciprocal relation self-referent assessment capabilities satisfaction, model determinism teacher is proposed. data 51,782 primary school teachers were analyzed using non-recursive causal struc...
