Neural Mechanisms Tracking Popularity in Real-World Social Networks

Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others’ popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets’ sociometric popularity, even when controlling for potential confounds. The target popularity–social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity–valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members’ popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior

Neural precursors of future liking and affective reciprocity

Why do certain group members end up liking each other more than others? How does affective reciprocity arise in human groups? The prediction of interpersonal sentiment has been a long-standing pursuit in the social sciences. We combined fMRI and longitudinal social network data to test whether newly acquainted group members’ reward-related neural responses to images of one another’s faces predict their future interpersonal sentiment, even many months later. Specifically, we analyze associations between relationship-specific valuation activity and relationship-specific future liking. We found that one’s own future (T2) liking of a particular group member is predicted jointly by actor’s initial (T1) neural valuation of partner and by that partner’s initial (T1) neural valuation of actor. These actor and partner effects exhibited equivalent predictive strength and were robust when statistically controlling for each other, both individuals’ initial liking, and other potential drivers of liking. Behavioral findings indicated that liking was initially unreciprocated at T1 yet became strongly reciprocated by T2. The emergence of affective reciprocity was partly explained by the reciprocal pathways linking dyad members’ T1 neural data both to their own and to each other’s T2 liking outcomes. These findings elucidate interpersonal brain mechanisms that define how we ultimately end up liking particular interaction partners, how group members’ initially idiosyncratic sentiments become reciprocated, and more broadly, how dyads evolve. This study advances a flexible framework for researching the neural foundations of interpersonal sentiments and social relations that—conceptually, methodologically, and statistically—emphasizes group members’ neural interdependence

"The Great Event of the Fortnight”: Steamship Rhythms and Colonial Communication

This paper engages with Tim Cresswell’s ‘contellations of mobility’ in order to contribute some understanding of historical maritime rhythms. The empirical focus is upon a steamship mail service in the post-emancipation Caribbean. In examining this communications network, it is stressed that while those managing the network valorised predictable efficiency, ‘friction’ was prized by mercantile groups at the steamers’ ports of call. Thus, the different aspects of mobility signified differently across the network, and this historical case study reinforces the resonance of slowness and stoppage time. The synchronisation of steamship arrivals with sociocultural norms in the Caribbean colonies also necessitated the adaptation of mail service rhythms. Through a focus on shipping operations, this paper proposes to temper our understanding of the role of steamship technology in empire. The influence of colonies on the metropole encompassed an alteration of the rhythms of imperial circulation, and it is within the maritime arena that these realities came into sharp focus

Pluralitas Agama dalam Keluarga Jawa

Dalam masyarakat Jawa terdapat pemahaman dan pemaknaan sendiri terhadap agama yaitu â€agami ageming ajiâ€. Artinya apa pun agama yang dipeluk sama saja karena semua agama mengajarkan keselamatan. Oleh sebab itu menjadi sebuah fenomena menarik di kalangan masyarakat Jawa karena mereka cenderung lebih toleran dalam menyikapi perbedaaan dan keragaman beragama. Salah satu contoh masyarakat yang menghargai pluralitas agama adalah masyarakat Desa Getas Kaloran Temanggung. Tujuan penelitian ini adalah untuk menjelaskan tentang sejumlah keluarga yang dapat menerima pluralitas agama dan toleransi terhadap pluralitas agama dalam keluarga Jawa. Tulisan ini merupakan hasil penelitian yang menggunakan pendekatan deskriptif kualitatif. Subyek penelitian adalah masyarakat Desa Getas yang memiliki keragaman agama dalam keluarganya. Berdasarkan hasil penelitian dapat disimpulkan bahwa masyarakat Desa Getas dapat menerima pluralitas agama karena menurut mereka agama adalah urusan pribadi seseorang jadi tidak ada pihak yang dapat memaksakan suatu keyakinan kepada individu lain. Pluralitas agama tersebut tidak menimbulkan masalah berarti karena masyarakat memiliki derajat toleransi yang tinggi antar anggota keluarga, yang ditunjukkan melalui saling menghargai dan mengormati dan tidak mencampuri urusan keagamaan orang lain, serta saling membantu antar anggota keluarga untuk memperlancar kegiatan ibadah masing – masing. In Javanese community there is a specific principle on the meaning of religion, namely â€agami ageming ajiâ€. This pilosophy means whatever religion people believe, it doesn’t matter because they all teach salvation. This is an interesting phenomenon among the Javanese community because they tend to be tolerant in dealing with differences and diversity of religion that happen in one household. The objective of this article is to discuss the practices of religious tolerance found in a rural community of Getas, Kaloran, Temanggung Central Java. Techniques of data collection is done by interviews and observation. The study subjects were villagers of Getas, which has a diversity of religion in families. Based on the research results, it can be concluded that the villagers embrace a tradition of religious pluralism because they think religion is one’s personal affairs so that no party can impose a conviction for another individual. The plurality of religion does not cause significant problems because the public has a high degree of tolerance among family members, which is demonstrated through mutual respect and attitude not to interfere in religious affairs of others, and mutual help among family members to facilitate the worship activities of their relatives

Conviviality and Parallax in David Olusoga’s Black and British: A Forgotten History

Through examining the BBC television series, Black and British: A Forgotten History, written and presented by the historian David Olusoga, and in extending Paul Gilroy’s assertion that the everyday, banality of living with difference is now an ordinary part of British life, this article considers how Olusoga’s historicization of the black British experience reflects a convivial rendering of UK multiculture. In particular, when used alongside Žižek’s notion of parallax, it is argued that understandings of convivial culture can be supported by a historical importance that deliberately ‘shocks’ and, subsequently dislodges, popular interpretations of the UK’s ‘white past’. Notably, it is parallax which puts antagonism, strangeness and ambivalence at the heart of contemporary depictions of convivial Britain, with the UK’s cultural differences located in the ‘gaps’ and tensions which characterize both its past and present. These differences should not be feared but, as a characteristic part of our convivial culture, should be supplemented with historical analyses that highlight but, also, undermine, the significance of cultural differences in the present. Consequently, it is suggested that if the spontaneity of conviviality is to encourage openness, then, understandings of multiculturalism need to go beyond reification in order to challenge our understandings of the past. Here, examples of ‘alterity’ are neither ‘new’ nor ‘contemporary’ but, instead, constitute a fundamental part of the nation’s history: of the ‘gap’ made visible in transiting past and present

On the Matter of Time

Drawing on several disciplinary areas, this article considers diverse cultural concepts of time, space, and materiality. It explores historical shifts in ideas about time, observing that these have gone full circle, from visions in which time and space were conflated, through increasingly divergent linear understandings of the relationship between them, to their reunion in contemporary notions of space-time. Making use of long-term ethnographic research and explorations of the topic of Time at Durham University’s Institute of Advanced Study (2012–13), the article considers Aboriginal Australian ideas about relationality and the movement of matter through space and time. It asks why these earliest explanations of the cosmos, though couched in a wholly different idiom, seem to have more in common with the theories proposed by contemporary physicists than with the ideas that dominated the period between the Holocene and the Anthropocene. The analysis suggests that such unexpected resonance between these oldest and newest ideas about time and space may spring from the fact that they share an intense observational focus on material events. Comparing these vastly different but intriguingly compatible worldviews meets interdisciplinary aims in providing a fresh perspective on both of them

Unfitting, uncomfortable, unacademic: a sociological reading of an interactive mobile phone app in university lectures

Abstract Scholarly literature on education technology uptake has been dominated by technological determinist readings of students’ technology use. However, in recent years there has been a move by sociologists of education to highlight how the contexts in which educational technologies are introduced are not tabula rasa but socially and culturally complex. This study approaches technology as a social construct, arguing that students construct discursive meaning of, rather than simply respond to, technologies for learning. The study explores students’ constructions of a mobile learning app that was introduced into lectures during a year-long university course. Students largely rejected the app, constructing it as unfitting for the context, a socially uncomfortable experience and an unacademic way of learning. The paper highlights the limitations of technological determinism and closes by arguing for readings of educational technologies that pay close attention to students’ voices

The nation in context: how intergroup relations shape the discursive construction of identity continuity and discontinuity

The perceived collective continuity (PCC) of a national identity serves as a crucial source of stability and self‐esteem for group members. Recent work has explored the consequences of perceived continuity when the meaning of a nation’s past is seen in a negative light, and the challenges this brings for the negotiation of a positive identity in the present, signalling the potential value of perceived discontinuity The current paper extends this literature by examining the role of intergroup relations in the construction of both collective continuities and discontinuities. Through analysing the discursive management of national identity in nine focus groups in a post‐conflict context (Serbia, N = 67), we reveal how the tensions between continuity and discontinuity are embedded within a broader discussion of the nation’s relationship with relevant national outgroups across its history. The findings contribute to theoretical knowledge on the interlinking of national identity and PCC by illustrating the ways in which intergroup relations of the past shape the extent to which continuity is seen as desirable or undesirable. We argue that despite the psychological merits of collective continuity, discontinuity can become attractive and useful when there is limited space to challenge how a nation’s history is remembered and the valence given to the past. The paper concludes by offering an account of how social and political contexts can influence the nature, functions, and valence of PCC within national identities

Discovering temporal regularities in retail customers’ shopping behavior

In this paper we investigate the regularities characterizing the temporal purchasing behavior of the customers of a retail market chain. Most of the literature studying purchasing behavior focuses on what customers buy while giving few importance to the temporal dimension. As a consequence, the state of the art does not allow capturing which are the temporal purchasing patterns of each customers. These patterns should describe the customerâ\u80\u99s temporal habits highlighting when she typically makes a purchase in correlation with information about the amount of expenditure, number of purchased items and other similar aggregates. This knowledge could be exploited for different scopes: set temporal discounts for making the purchases of customers more regular with respect the time, set personalized discounts in the day and time window preferred by the customer, provide recommendations for shopping time schedule, etc. To this aim, we introduce a framework for extracting from personal retail data a temporal purchasing profile able to summarize whether and when a customer makes her distinctive purchases. The individual profile describes a set of regular and characterizing shopping behavioral patterns, and the sequences in which these patterns take place. We show how to compare different customers by providing a collective perspective to their individual profiles, and how to group the customers with respect to these comparable profiles. By analyzing real datasets containing millions of shopping sessions we found that there is a limited number of patterns summarizing the temporal purchasing behavior of all the customers, and that they are sequentially followed in a finite number of ways. Moreover, we recognized regular customers characterized by a small number of temporal purchasing behaviors, and changing customers characterized by various types of temporal purchasing behaviors. Finally, we discuss on how the profiles can be exploited both by customers to enable personalized services, and by the retail market chain for providing tailored discounts based on temporal purchasing regularity
