Although various norms for reciprocity-based cooperation have been suggested that are evolutionarily stable against invasion from free riders, the process of alternation of norms and the role of diversified norms remain unclear in the evolution of cooperation. We clarify the co-evolutionary dynamics of norms and cooperation in indirect reciprocity and also identify the indispensable norms for t...

" Social norms " is a term widely used in different areas of research like sociology, philosophy or multiagent systems. However, there is still not a clear definition of what social norms are and the types of problems they solve. This work presents a general classification and distinction of norms from a game theoretical perspective. The type of norms treated in this work are those norms create...

Humans can be characterized by a disposition to act, to believe and to feel in ways that are guided by norms and correspondingly by a disposition to experience certain feelings when norms are violated. Norms are fundamental to social life and the capacity to accept norms is a universal human biological and social adaptation. Norms serve the function of coordinating actions, beliefs, and feeling...

Conversations over who should be identified as gifted continue perpetually both within the field and in popular media. In this article, we focus on use of local norms one approach to identification that can increase equity advanced educational programs services while also better achieving their stated purpose providing additional challenge those students need it. define norms, explain purpose, ...

In open multi-agent systems norms describe the behavior that can be performed, that must be performed, and that cannot be performed. One of the main challenges on developing normative systems is that norms may conflict with each other. Norms are in conflict when the fulfillment of one norm violates the other and vice-versa. Although there are many approaches to check for conflicts among norms, ...

In open normative multi-agent systems, norms are created dynamically. Some of these norms emerge and persist due to their benefits and strength. While other norms emerge for a short period of time, then vanish due to several reasons that lead to loss in their benefit or strength. Each norm of the created ones might have positive, negative, or neutral consequences on the system. Norms decay refe...

In multi-agent systems, software agents are modelled to possess characteristics and behaviour borrowed from human societies. Norms are expectations of behaviours of the agents in a society. Norms can be established in a society in different ways. In human societies, there are several types of norms such as moral norms, social norms and legal norms (laws). In artificial agent societies, the desi...

INTRODUCTION Alcohol use among young people is a major public health concern in Australia and internationally. Research elucidating social norms influencing alcohol use supports the desire to conform to peers. However, there is a lack of evidence on how social norms are transmitted from the community to young people and between family members and peers, as previous studies are limited to mainly...

One of the leitmotifs of the ecophysiological research on ectotherms is the variation and evolution of thermal reaction norms for biological rates. This long-standing issue is crucial both for our understanding of life-history diversification and for predicting the phenology of economically important species. A number of properties of the organism's thermal phenotype have been identified as pot...
