Social functioning involves learning about the social networks in which we live and interact; knowing not just our friends, but also who is friends with our friends. This study utilized an incidental learning paradigm and representational similarity analysis (RSA), a functional MRI multivariate pattern analysis technique, to examine the relationship between learning social networks and the brain’s response to the faces within the networks. We found that accuracy of learning face pair relationships through observation is correlated with neural similarity patterns to those pairs in the left temporoparietal junction (TPJ), the left fusiform gyrus, and the subcallosal ventromedial prefrontal cortex (vmPFC), all areas previously implicated in social cognition. This model was also significant in portions of the cerebellum and thalamus. These results show that the similarity of neural patterns represent how accurately we understand the closeness of any two faces within a network. Our findings indicate that these areas of the brain not only process knowledge and understanding of others, but also support learning relations between individuals in groups.

AbstractSocial functioning involves learning about the social networks in which we live and interact; knowing not just our friends, but also who is friends with our friends. Here we utilized a novel incidental learning paradigm and representational similarity analysis (RSA), a functional MRI multivariate pattern analysis technique, to examine the relationship between learning social networks and the brain's response to the faces within the networks. We found that accuracy of learning face pair relationships through observation is correlated with neural similarity patterns to those pairs in the left temporoparietal junction (TPJ), the left fusiform gyrus, and the subcallosal ventromedial prefrontal cortex (vmPFC), all areas previously implicated in social cognition. This model was also significant in portions of the cerebellum and thalamus. These results show that the similarity of neural patterns represent how accurately we understand the closeness of any two faces within a network, regardless of their true relationship. Our findings indicate that these areas of the brain not only process knowledge and understanding of others, but also support learning relations between individuals in groups.Significance StatementKnowledge of the relationships between people is an important skill that helps us interact in a highly social world. While much is known about how the human brain represents the identity, goals, and intentions of others, less is known about how we represent knowledge about social relationships between others. In this study, we used functional neuroimaging to demonstrate that patterns in human brain activity represent memory for recently learned social connections.

Starting from the example of San Miniato al Monte, the essay dwells on the relationship existing between Florentine aristocracy and religious institutions. These were indispensable elements for the occupation of the urban ‘political space’, thanks to the social networks they controlled. Their political role – until now poorly investigated – was clearly recognised by the new ruling groups (Popolo). For this reason, the Florentine Popolo’s regime at the end of the thirteenth century tried to break the connection between aristocratic families and religious institutions, also through the use of precise rules that had become part of the Ordinamenti di Giustizia.

Aquaculture of Cage Culture is one of the main activities carried out by the community in the village of Haranggaol to fulfill their economic needs. This cultivation business establishes a relationship between traders and cages in terms of marketing their crops. There are 3 egocentric actors in the Haranggaol area. They are collectors (entrepreneurs/farmers who own capital), namely the Rohakinian group, the Siharo group, and the Paimaham group. Through these three egocentric actors, a social network is formed with several alters. Based on the qualitative approach with use Ucinet software, the mapping of their social networks can be seen as follows: alter actors connected to the Rohakinian group are 12 farmers in the group and 2 farmers outside the group with a density of 0.033. There are 27 alter actors connected to the Siharo group, 21 from the group and 6 from outside the group with a density of 0.014. There are 27 alter actors connected to the Paimaham group, namely 36 farmers from their groups and 10 farmers outside the group with a density of 0.005. The social networks that occur between these actors are intertwined due to the existence of kinship relationships, family or close friends who know each other among them. The relationship between family, family or close friends built with mutual trust make this network integrated.

Abstract Altruism is a puzzling phenomenon, especially for Biology and Economics. Why do individuals reduce their chances to provide some of the resources they own to others? The answer to this question can be sought at ultimate or proximate levels of explanation. The Social Neurosciences attempt to specify the brain mechanisms that drive humans to act altruistically, in assuming that overtly identical behaviours can be driven by different motives. The research has shown that activations and functional connectivities of the Anterior Insula and the Temporoparietal Junction play specific roles in empathetic versus strategic forms of altruism, whereas the dorsolateral prefrontal cortex, among other regions, is involved in norm-oriented punitive forms of altruism. Future research studies could focus on the processing of ambiguity and conflict in pursuit of altruistic intentions.

Purpose This study aims to investigate how workplace resourcefulness (positive psychological climate), as well as personal resources (psychological capital [PsyCap]), influence work engagement to promote change-oriented organizational citizenship behaviors (Ch-OCBs) among Indian information technology (IT) personnel. Design/methodology/approach The social exchange theory and job demands-resources model are used to provide rationale for proposing a comprehensive mechanism including antecedents, moderators as well as mediators enabling Ch-OCBs among IT personnel. Structured questionnaires were administered targeting IT professionals and their supervisors to test the proposed relationships. The obtained data from 30 supervisors and 240 subordinates were tested using confirmatory factor analysis, SEM and moderated path analysis technique. Findings Psychological climate, PsyCap and work engagement positively relate to Ch-OCBs; PsyCap moderated the relationship between psychological climate and work engagement. Specifically, the relationship between psychological climate and work engagement has come out stronger for employees with high PsyCap. Work engagement fully mediated the relationship between psychological climate and Ch-OCBs. Practical implications The findings can be critical in promoting voluntary change-focused behaviors among Indian IT personnel, for Indian and foreign (non-Indian) multi-national corporations that are interested in reaping profits by availing change-driven extra-role services of their efficient and the most preferred Indian IT employees of the world. Originality/value This study addresses to the call for more research on change-focused promotive part of OCB and advances the literature by providing evidence on the proposed set of associations from fast-pacing Indian economy.

Carnivalesque theory has been used as a model and a structure in the works carried out in many fields such as communication, literature, and sociology. In fact, Carnivalesque appears in many environments/areas, particularly in the social networks, which are the manifestation of social life. This chapter examines social networks in the context of carnivalesque theory to reveal facts of carnivalesque in Twitter. Content analysis technique was used in the research. Research data came from 10 Twitter accounts which have a maximum number of followers in Turkey. These data were analyzed and examined in terms of grotesque, dialogism, carnival laughter, upside-down world, marketplace, and marketplace speech belonging to the carnivalesque theory. According to the findings, the structure of Twitter, which is one of the most popular social networks in Turkey, is largely similar to the structure of the carnival and features of carnivalesque theory.

The Relationship

In social networks, individuals are usually but not exactly divided into communities such that within each community people are friendly to each other while being hostile towards other communities. This is in line with structural balance theory which enables a comprehensive understanding of the stability and tensions of social systems. Yet, there may be some conflicts such as the intra-community negative edges or inter-community positive edges that affect the balancedness of the social system. This raises an interesting question of how to partition a signed network for minimal conflicts, i.e., maximum balancedness. In this paper, by analyzing the relationship between balancedness and spectrum space, we find that each eigenvector can be an indicator of dichotomous structure of networks. Incorporating the leader mechanism, we partition signed networks to maximize the balancedness with top-k eigenvectors. Moreover, we design an optimizing segment to further improve the balancedness of the network. Experimental data both from real social and synthetic networks demonstrate that the spectral algorithm has higher efficiency, robustness and scientificity.

How does the brain translate an internal representation of an object into a decision about the object's category? Recent studies have uncovered the structure of object representations in inferior temporal cortex (IT) using multivariate pattern analysis methods. These studies have shown that representations of individual object exemplars in IT occupy distinct locations in a high-dimensional activation space, with object exemplar representations clustering into distinguishable regions based on category (e.g., animate vs. inanimate objects). In this study, we hypothesized that a representational boundary between category representations in this activation space also constitutes a decision boundary for categorization. We show that behavioral RTs for categorizing objects are well described by our activation space hypothesis. Interpreted in terms of classical and contemporary models of decision-making, our results suggest that the process of settling on an internal representation of a stimulus is itself partially constitutive of decision-making for object categorization.
