Social categorization processes may lead work groups to form different types of group norms. We present a model of norm formation and suggest that group norms may emerge immediately following the group’s inception. Further, the content of such norms may be influenced by group members’ demographic heterogeneity. We outline a profile of work group norms and describe how social categorization proc...

Abstract Cryptocurrency has become a hot area of global investment. Despite the increasing regulation cryptocurrencies, some investors are still obsessed with investing in and reasons behind this worth exploring. Emerging studies from cryptocurrency behavioural perspective demonstrate that investments influenced by variety factors, but ignore objective factor political environment. Based on soc...

This descriptive study looked into Persian learners’ autonomy and its ties with in-class group dynamics. The participants were undergraduate learners and M.A. students together with their teachers. Data were collected, using a questionnaire, on the participants’ beliefs about autonomy, their autonomous behaviors, and their perceptions of group norms and group cohesiveness. Corresponding teacher...

The effects of social group norms (inclusion vs. exclusion vs. exclusion-plus-relational aggression) and school norms (inclusion vs. no norm) on 7- and 10-year-old children's intergroup attitudes were examined. Children (n = 383) were randomly assigned to a group with an inclusion or exclusion norm, and to 1 of the school norm conditions. Findings indicated that children's out-group attitudes r...

Group beneficial norms are common in human societies. The persistence of such norms is consistent with evolutionary game theory, but existing models do not provide a plausible explanation for why they are common. We show that when a model of imitation used to derive replicator dynamics in isolated populations is generalized to allow for population structure, group beneficial norms can spread ra...

Each t-norm can be identified with its Cayley tomonoid, which consists of pairwise commuting order-preserving functions from the real unit interval to itself. Cayley tomonoids provide an easily manageable, yet versatile tool for the construction of t-norms. To give evidence to this claim, we review and reformulate several construction methods that are known in the literature. We adopt, on the o...
