In this work, by using norms (t-norms and t-conorms), Q-intuitionistic fuzzy subgroups of a group are defined investigated some their properties structured characteristics.

Past research on the social identity approach to attitude-behaviour relations has operationalized group norms as a mixture of both descriptive information (i.e. what most people do themselves) and injunctive information (i.e. what most people approve of). Two experiments (Study 1=185 participants; Study 2=238 participants) were conducted to tease apart the relative effects of descriptive and in...

Manipulation of in-group and out-group norms of discrimination and fairness allowed for the operation of competing social identity principles concerning in-group bias, conformity, and group distinctiveness. The combined effects of these principles on in-group bias were first examined in a modified minimal-group setting (Study 1). Results demonstrated that participants' allocation strategies wer...

We analyze a class of norms defined via an optimal interpolation problem involving the composition of norms and a linear operator. This construction, known as infimal postcomposition in convex analysis, is shown to encompass various of norms which have been used as regularizers in machine learning, signal processing, and statistics. In particular, these include the latent group lasso, the overl...
