given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

Trust in financial institutions is widely considered important. However, a clear overview of studies on the drivers trust missing. We intend to fill this gap literature. After discussing why important, we turn its measurement, where distinguish between one's own institution and general (narrow-scope broad-scope trust), discuss how these measures differ from generalized (i.e. other people with w...

Intergroup relations theory posits that cross-group friendship reduces threat perceptions and negative emotions about outgroups. This has been argued to mitigate the effects of ethnic diversity on generalized trust. Yet, direct tests this friendship-trust relation, especially including affect as mediators, have remained rare at individual level. In article, we bridge research gap using represen...

In this paper, we investigate the use of DC (Difference of Convex functions) models and algorithms in the solution of nonlinear optimization problems by trust-region methods. We consider DC local models for the quadratic model of the objective function used to compute the trust-region step, and apply a primal-dual subgradient method to the solution of the corresponding trust-region subproblems....
