Time as a limited resource: Communication strategy in mobile phone networks

We used a large database of 9 billion calls from 20 million mobile users to examine the relationships between aggregated time spent on the phone, personal network size, tie strength and the way in which users distributed their limited time across their network (disparity). Compared to those with smaller networks, those with large networks did not devote proportionally more time to communication and had on average weaker ties (as measured by time spent communicating). Further, there were not substantially different levels of disparity between individuals, in that mobile users tend to distribute their time very unevenly across their network, with a large proportion of calls going to a small number of individuals. Together, these results suggest that there are time constraints which limit tie strength in large personal networks, and that even high levels of mobile communication do not fundamentally alter the disparity of time allocation across networks.     

Social networks and Internet connectivity effects

This paper explores the impact of communication media and the Internet on connectivity between people. Results from a series of social network studies of media use are used as background for exploration of these impacts. These studies explored the use of all available media among members of an academic research group and among distance learners. Asking about media use as well as about the strength of the tie between communicating pairs revealed that those more strongly tied used more media to communicate than weak ties, and that media use within groups conformed to a unidimensional scale, showing a configuration of different tiers of media use supporting social networks of different ties strengths. These results lead to a number of implications regarding media and Internet connectivity, including: how media use can be added to characteristics of social network ties; how introducing a medium can create latent tie connectivity among group members that provides the technical means for activating weak ties, and also how a change in a medium can disrupt existing weak tie networks; how the tiers of media use also suggest that certain media support different kinds of information flow; and the importance of organization-level decisions about what media to provide and promote. The paper concludes with a discussion of implications for Internet effects.     

Residential mobility and the spatial dispersion of personal networks: Effects on social support

Using a representative national sample of personal networks, this article explores how the spatial dispersion of networks, residential mobility and social support are linked. Three issues will be addressed here. Firstly, how is the spatial dispersion of personal networks related to individuals’ social characteristics, network composition and residential mobility? Secondly, how do the spatial dispersion of networks, residential mobility and their combined effect influence the number and (thirdly) the structure of emotional support ties? Results showed that the extent of the support was affected neither by the geographical distribution of the networks nor by residential mobility. Living far from one's birthplace, however, exerted two distinct, and opposite effects on the support network structure. On the one hand, mobility led to high spatial dispersion of personal contacts, which in turn favored a sparsely knit network centered around the mobile individual. On the other hand, by controlling for the effect of distance between the contacts, we found that individuals that cited long-distance ties tended to be part of more transitive support networks than those that cited local ties. We interpreted the latter effect as evidence that transitive ties may survive greater spatial distances than intransitive ones. These findings are discussed in view of spatial mobility and social network research.

Abstract

A perennial issue in both rural and urban sociology has been whether or not size of place is associated with differences in the way that individuals relate to one another. This paper examines the relationship between size of place and the structural properties of personal social networks through the mediating effects of residential stability. Social network data from the General Social Survey (National Opinion Research Center 1990) provide support for the hypothesis that residential stability explains the association between size of place and social network density. The implications of these findings for community theory are discussed.     

The Emergence and Stability of Groups in Social Networks

An important puzzle in social network research is to explain how macro-level structures emerge from micro-level network processes. Explaining the emergence and stability of structural groups in social networks is particularly difficult for two reasons. First, because groups are characterized both by high connectedness within (group cohesion) and lack of connectedness between them (group boundaries). Second, because a large number of theoretical micro-level network processes contribute to their emergence. We argue that traditional social network theories that are concerned with the evolution of positive relations (forces of attraction) are not sufficient to explain the emergence of groups because they lack mechanisms explaining the emergence of group boundaries. Models that additionally account for the evolution of negative ties (forces of repulsion) may be better suited to explain the emergence and stability of groups. We build a theoretical model and illustrate its usefulness by fitting stochastic actor-oriented models (SAOMs) to empirical data of co-evolving networks of friendship and dislike among 479 secondary-school students. The SAOMs include a number of newly developed effects expressing the co-evolution between positive and negative ties. We then simulate networks from the estimated models to explore the micro-macro link. We find that a model that considers forces of attraction and repulsion simultaneously is better at explaining groups in social networks. In the long run, however, the empirically informed simulations generate networks that are too stylized to be realistic, raising further questions about model degeneracy and time heterogeneity of group processes.     

From attitudes to social networks: National gender-role attitudes and gender differences in late-life social relationships

Studies often find gender differences in social networks in later life, but are these findings universal, or do they differ in various cultural contexts? To address this research gap, the current study examines the association between gender differences in social relationships and country-level gender-role attitudes. We combined data from the Survey of Health, Ageing and Retirement in Europe (SHARE) of individuals aged 50 years and older with country-level data on gender-role attitudes from the European Values Survey (EVS) for 15 European countries. We estimated a series of multivariate hierarchical regression models that predicted the size of the personal social network, its emotional closeness, and the proportion of the spouse, children, and friends in the network. The results indicated gender differences in social network characteristics. Women reported larger social networks and were more likely to have larger proportions of children and friends but smaller proportions of the spouse in their social networks. The magnitude of gender differences was associated with country-level gender-role attitudes. In countries with more egalitarian gender-role attitudes, women had larger networks with a larger proportion of friends compared to men. In countries with more traditional gender-role attitudes, women had larger proportions of their children and spouse in their social networks and had emotionally closer networks. Our findings suggest that the societal context and opportunity structures for social interactions play an important role in shaping the structure of women’s and men’s social relationships in later life.     

Family comes first: Men's and women's personal networks in Tehran

This paper examines the characteristics of middle class Tehranis’ networks, based upon a survey of 318 individuals from the 159 households. The results show that women and men have similar-size networks. However, their networks differ substantially in gender composition, with each having almost two-thirds of network members of their own gender. Men's and women's networks contain a large proportion of kin overall. Most ties tend to be with immediate kin: children, parents and siblings. An immediate kin is usually the socially closest member of a network. Apart from voluntary factors, the importance of kinship ties in men's and women's networks may be the result of the macro-structural conditions under which patterns of social relationships take place.     

Political information use on WeChat and political discussion in China: toward a networked political discussion model

This study was conducted to test the relationships between WeChat (a popular Chinese mobile SNS) and a number of variables including the structural features of users’ networks, the use of political information on WeChat, political discussions, and political attitudes. The results of this study showed that the use of political information by WeChat users on this platform affected their political discussions and political attitudes. Furthermore, both positive and negative WeChat political discussions mediated the effects of the use of political information on political attitudes. Additionally, the connectedness of networks significantly lowered the likelihood of individual users to comment negatively on politics. These findings indicate that WeChat users with diverse social networks are more likely to engage in positive political discussions than in negative political discussions. The theoretical and practical implications of this study are discussed.     

Communicating social value: An experimental study on credible communication and social enterprises

The management of marketing and communication strategies involves a complex mix of different requirements, particularly for social enterprises, which try to fulfill both social and business aims while operating in a resource-constrained context. Although social enterprises are a rising phenomenon, the research on how these businesses communicate their activities remains in its infancy. This study builds on the theory of planned behavior and the source credibility theory, presenting a conceptual framework that distinguishes between high, moderate, and low credibility of a social enterprise's communication, to analyze its effects on potential customers' behavioral intentions. Through an online experiment with 260 subjects, the authors demonstrate that attitude toward a social enterprise, subjective norm, perceived behavioral control, and, ultimately, the intention to support a social enterprise by purchasing its products increases with the social enterprise's message credibility. The authors also present practical implications and avenues for future research on the communication of social enterprises based on the empirical findings.     

Corporate competition: A self-organized network

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and modeling the spatial structure of a large interfirm competition network across a variety of sectors and industries within the United States. We propose two micro-dynamic models that are able to reproduce empirically observed characteristics of competition networks as a natural outcome of a minimal set of general mechanisms governing the formation of competition networks. Both models, which utilize different approaches yet apply common principles to network formation give comparable results. There is an asymmetry between companies that are considered competitors, and companies that consider others as their competitors. All companies only consider a small number of other companies as competitors; however, there are a few companies that are considered as competitors by many others. Geographically, the density of corporate headquarters strongly correlates with local population density, and the probability two firms are competitors declines with geographic distance. We construct these properties by growing a corporate network with competitive links using random incorporations modulated by population density and geographic distance. Our new analysis, methodology and empirical results are relevant to various phenomena of social and market behavior, and have implications to research fields such as economic geography, economic sociology, and regional economic development.     

The role of network setting and gender in online content popularity

In this study, we explore the role of specific network structures that enhance social capital and assess the extent to which gender, social ties, and communication interaction relate to content popularity within online social networks (OSNs). Our results are based on an extensive OSN data set, containing over 100,000 members, connected by over 1.7 million links. The findings indicate that content popularity inference is more accurate when considering activity interaction among users and that network structures known as advantageous for amassing social capital in the offline environment are relevant online as well. We conclude by discussing how gender mediates the correlation between some network measures and the growth of users’ content popularity and provide a potential explanation for the emergence of gender differences.     

Rewiring global networks at local events: congresses in the stock photo trade

Digital technologies have enabled the geographical expansion of production and the distribution of creative goods and communication. Simultaneously, the number of trade fairs and congresses has increased. This rise of temporary encounters has led to theorizations of events as marketplaces, learning sites and field‐configuring practices. This article elaborates on the metaphor of rewiring to propose and empirically demonstrate a further role of industry events for global business. Drawing on the case of the global stock photo trade, we use a unique survey to map the global network of sales partnerships as well as interviews conducted at international lead congresses to demonstrate how these events are enacted as social relays. Our findings demonstrate how temporary face‐to‐face contact facilitates long distance relationships between organizations and how it dynamically shapes the global industry network. Thus, we contribute to closing the gap between social action at the micro level, organizational linkages at the meso level and the structure of global industry networks at the macro level.     

Disliking friends of friends in schools: How positive and negative ties can co-occur in large numbers

Current network scholarship does not explain why negative and positive ties both frequently occur in large numbers in some settings, such as schools. In the present paper, I argue that this can happen when people disproportionately send negative ties to socially close individuals (‘friends of friends’). I propose a new theory—‘intensity theory’—which argues that disliking ties disproportionately occur between friends of friends in ‘intense foci’. Intense foci are settings that concentrate social relations, and in which other people are difficult to avoid. I draw on a mixed-methods case study of a boarding school and several strands of literature to substantiate the theory. In so doing, I offer a new mechanism for the initial appearance of disliking ties, propose a contextual approach to balance theory and networks in general, and suggest a more complex view of the link between positive and negative ties.     

More or less guanxi: Trust is 60% network context, 10% individual difference

The strong ties known in China as guanxi can be distinguished by a high level of trust relatively independent of the surrounding social structure. Using network data from a stratified probability sample of 700 entrepreneurs citing 4664 contacts, we study guanxi relative to other relations to learn how much individual differences such as well-being, business differences, political participation and demographic factors matter for the guanxi distinction. Two findings stand out: First, the connection between trust and social network is robust to most differences between individuals, especially business and political differences. Trust variance is 60% network context, and 10% individual differences. Trust increases within a relationship as network closure increases around the relationship, but some relationships mature into guanxi ties within which trust is high and relatively independent of the surrounding social structure. Second, when individual differences matter, they concern social isolation. Guanxi ties are more distinct in the networks around entrepreneurs with small, marginal families, and around those with small, closed networks. Both categories of entrepreneurs are likely to experience difficulties with respect to resource access and doing business with people beyond their network, which may explain why longstanding guanxi ties linked to important events are particularly distinct for these entrepreneurs.     

Networks and geography: Modelling community network structures as the outcome of both spatial and network processes

This paper focuses on how to extend the exponential random graph models to take into account the geographical embeddedness of individuals in modelling social networks. We develop a hierarchical set of nested models for spatially embedded social networks, in which, following Butts (2002), an interaction function between tie probability and Euclidean distance between nodes is introduced. The models are illustrated by an empirical example from a study of the role of social networks in understanding spatial clustering in unemployment in Australia. The analysis suggests that a spatial effect cannot solely explain the emergence of organised network structure and it is necessary to include both spatial and endogenous network effects in the model.     

Neighborhoods in the Network Society the e-Neighbors study

This study examines whether the Internet is increasingly a part of everyday neighborhood interactions, and in what specific contexts Internet use affords the formation of local social ties. Studies of Internet and community have found that information and communication technologies provide new opportunities for social interaction, but that they may also increase privatism by isolating people in their homes. This paper argues that while the Internet may encourage communication across great distances, it may also facilitate interactions near the home. Unlike traditional community networking studies, which focus on bridging the digital divide, this study focuses on bridging the divide between the electronic and parochial realms. Detailed, longitudinal social network surveys were completed with the residents of four contrasting neighborhoods over a period of three years. Three of the four neighborhoods were provided with a neighborhood email discussion list and a neighborhood website. Hierarchical linear modeling (HLM) was used to model over time the number of strong and weak ties, emailed, met in-person, and talked to on the telephone. The neighborhood email lists were also analyzed for content. The results suggest that with experience using the Internet, the size of local social networks and email communication with local networks increases. The addition of a neighborhood email list further increases the number of weak neighborhood ties, but does not increase communication multiplexity. However, neighborhood effects reduce the influence of everyday Internet use, as well as the experimental intervention, in communities that lack the context to support local tie formation.     

Place,space, networks,and the sustainability of collective action: the Madres de Plaza de Mayo

This article provides a framework for analysing social movements and explaining how collective action can be sustained through networks. Drawing on current relational views of place and space, I offer a spatialized conception of social networks that critically synthesizes network theory, research on social movements, and the literature on the spatial dimensions of collective action. I examine the historic and contemporary network geographies of a group of human rights activists in Argentina (the Madres de Plaza de Mayo) and explain the duration of their activism over a period of more than two decades with regard to the concept of geographic flexibility. To be specific, first I show how, through the practice of place‐based collective rituals, activists have maintained network cohesion and social proximity despite physical distance. Second, I examine how the construction of strategic networks that have operated at a variety of spatial scales has allowed the Madres to access resources that are important for sustaining mobilization strategies. Finally, I discuss how the symbolic depiction of places has been used as a tool to build and sustain network connections among different groups. I conclude by arguing that these three dimensions of the Madres’ activism account for their successful development of geographically flexible networks, and that the concept of geographic flexibility provides a useful template for studies of the duration and continuity of collective action.     

Social network and family business: Uncovering hybrid family firms

What does it mean for a private enterprise in China to be embedded in a family? Our purpose here is twofold: (1) use social network analysis to describe what it means for a firm to be embedded in a family, (2) reveal from the application a new kind of firm, not family, yet akin to family. Armed with data on a large probability sample of private enterprises — a third of which meet ownership and employment criteria of being family businesses — we uncover a category of “hybrid family firms” that look modern in the style of firms that exclude family, but operate socially in ways similar to family firms. Our conclusion from summary statistics on the sample is that there are no differences in average performance level or network advantage for the three categories of businesses: family firms, hybrid family firms, and family-excluded firms. The fact that CEOs of family firms and hybrid family firms more often turn to family as key business contacts is a fact about network composition that raises no question about network mechanisms. Whether the CEO turns to more or fewer family contacts, government help is more likely with stronger political connections, and business success and survival are more likely with a large, open network. That said, the look-modern, act-traditional hybrid family firms stand alone in prospering with a CEO embedded in a closed business network. Recognition of hybrid family firms adds to the literature’s illustrations of social network analysis used to distinguish types of businesses and business people, and extends the population of organizations within which governance and strategy are likely to be better understood when viewed through a family logic.     

Social media,small businesses,and the control of information

Much of the discussion regarding privacy and social media has focused on consumers of social media, but social media is also popular among businesses. This article explores the privacy tensions of small business owners using social media to disseminate and gather information to better engage and serve their customers while maintaining customer trust. Drawing on Communication Privacy Management theory [Petronio, S. (2002). Boundaries of privacy: Dialectics of disclosure. Albany, NY: SUNY Press, Petronio, S. (2007). Translational research endeavors and the practices of communication privacy management. Journal of Applied Communication Research, 35(3), 218–222], we argue that there is a dialectical tension between control and engagement. As information is disclosed via social media, it creates new opportunities for engagement, surveillance, and commodification. Based on group interviews with small business owners, we identify the kinds of information that small businesses must manage as participants on social media platforms and the privacy rules they develop.     

Global Nomads' Network and Mobile Sociality: Exploring New Media Uses on the Move

This paper explores the convergence of communication and travel and the emergence of a mobile and network sociality, through investigating new communication practices based on the internet and mobile phone enacted by backpackers while on the move. These global nomads produce and maintain mobile spaces of sociality, founded on a complex intersection of face-to-face interaction and mediated communication, co-presence and virtual proximity, corporeal travel and virtual mobilities. Personal communities become a mobile phenomenon, relocalized in a plurality of online and offline social spaces. It is thus argued that network relationships are reshaped and mobilized through reconfigurations of co-presence, proximity and distance in relation to the use of new media. Exploring new media uses on the move can thus provide a useful insight into the emerging social model of the network and mobile society.
