Norms have been used to represent desirable behaviours that software agents should exhibit in sophisticated multi-agent solutions. An important open research issue refers to group norms, i.e. norms that govern groups of agents. Depending on the interpretation, group norms may be intended to affect the group as a whole, each member of a group, or some members of the group. Moreover, upholding gr...

Let G be a locally compact group, and let 1 < p < ∞. In this paper we investigate the injectivity of the left L1(G)-module Lp(G). We define a family of amenability type conditions called (p, q)-amenability, for any 1 ≤ p ≤ q. For a general locally compact group G we show if Lp(G) is injective, then G must be (p, p)-amenable. For a discrete group G we prove that l p(G) is injective if and only i...

This paper examines the decentralized formation of groups within a multiagent normative society. In our case, a group is defined based on the set of social norms used by its members: all the agents using the same set of norms belong to the same social group. In this paper we explore different mechanisms that allow agents to recognize the others as members of a certain social group. Considering ...

The most widely used form of convolutional sparse coding uses an `1 regularization term. While this approach has been successful in a variety of applications, a limitation of the `1 penalty is that it is homogeneous across the spatial and filter index dimensions of the sparse representation array, so that sparsity cannot be separately controlled across these dimensions. The present paper consid...

To assess predictions from social identity development theory (SIDT; Nesdale, 2004) concerning children's ethnic/racial prejudice, 197 Anglo-Australian children ages 7 or 9 years participated in a minimal group study as a member of a team that had a norm of inclusion or exclusion. The team was threatened or not threatened by an out-group that was of the same or different race. Consistent with S...

This paper examines the decentralized recognition of groups within a multiagent normative society. In this work we explore different mechanisms that allow agents to recognize the others as members of a certain social group. Considering as the basic mechanism the one that makes agents interact with other agents without considering the previous interactions and with no communication, three new al...

Cultural group identity and group norms are significantly related to social exclusion evaluations (Bennett, ). This study examined 241 Jewish-American mid (M = 14.18 years, SD = 0.42) to late (M = 17.21 years, SD = 0.43; MageTOTAL  = 15.54 years, SD = 1.57) adolescents' cultural identities and contextually salient perceived group norms in relation to their evaluations of Arab-American inclusion...

In recent years, we have witnessed a resurgence of interest in the study of normative influences. The multitude of scholars who approach the topic from a variety of disciplinary perspectives widely share the convention, backed by strong empirical evidence, that social norms exert a great deal of influence on human behavior and that processes of normative influence exist in a variety of contexts...
