Good health and the bridging of structural holes

Bridges that span structural holes are often explained in terms of the entrepreneurial personalities or rational motivations of brokers, or structural processes that lead to the intersection of social foci. I argue that the existence and use of bridges in interpersonal networks also depends on individuals’ health. Poor health may make it more difficult to withstand the pressures and to execute some of the common tasks associated with bridging (e.g., brokerage). I examine this possibility using egocentric network data on over 2500 older adults drawn from the recent National Social Life, Health, and Aging Project (NSHAP). Multivariate regression analyses show that both cognitive and functional health are significantly positively associated with bridging, net of sociodemographic and life-course controls. The relationship between functional (kinesthetic) health and bridging appears to be partially mediated by network composition, as older adults who have poorer functional health also tend to have networks that are richer in strong ties. Several potential mediation mechanisms are discussed. Cognitive function remains significantly associated with bridging net of network composition, suggesting that the inherent challenges of maintaining bridging positions may be more difficult to cope with for those who have cognitive impairments than for those who have functional impairments such as limited mobility. An alternative explanation is that cognitively impaired individuals have more difficulty recognizing (and thus strategically using) bridges in their networks. Theoretical implications and possibilities for future research are discussed.     

Connected seniors: how older adults in East York exchange social support online and offline

ABSTRACT

How do older adults mobilize social support, with and without digital media? To investigate this, we focus on older adults 65+ residing in the Toronto locality of East York, using 42 interviews lasting about 90 minutes done in 2013–2014. We find that digital media help in mobilizing social support as well as maintaining and strengthening existing relationships with geographically near and distant contacts. This is especially important for those individuals (and their network members) who have limited mobility. Once older adults start using digital media, they become routinely incorporated into their lives, used in conjunction with the telephone to maintain existing relationships but not to develop new ones. Contradicting fears that digital media are inadequate for meaningful relational contact, we found that these older adults considered social support exchanged via digital media to be real support that cannot be dismissed as token. Older adults especially used and valued digital media for companionship. They also used them for coordination, maintaining ties, and casual conversations. Email was used more with friends than relatives; some Skype was used with close family ties. Our research suggests that policy efforts need to emphasize the strengthening of existing networks rather than the establishment of interventions that are outside of older adults’ existing ties. Our findings also show that learning how to master technology is in itself a form of social support that provides opportunities to strengthen the networks of older adults.     

Network recall among older adults with cognitive impairments

Although it is widely accepted that personal networks influence health and illness, network recall remains a major concern. This concern is heightened when studying a population that is vulnerable to cognitive decline. Given these issues, we use data from the Social Network in Alzheimer Disease project to explore similarities and discrepancies between the network perceptions of focal participants and study partners. By leveraging data on a sample of older adults with normal cognition, mild cognitive impairment, and early stage dementia, we explore how cognitive impairment influences older adults’ perceptions of their personal networks. We find that the average individual is more likely to omit weaker, peripheral ties from their self-reported networks than stronger, central ties. Despite observing only moderate levels of focal-partner corroboration across our sample, we find minimal evidence of perceptual differences across diagnostic groups. We offer two broad conclusions. First, self-reported network data, though imperfect, offer a reasonable account of the core people in one’s life. Second, our findings assuage concerns that cognitively impaired older adults have skewed perceptions of their personal networks.     

Goal specific social capital and job satisfaction: Effects of different types of networks on instrumental and social aspects of work

This paper addresses the question “To what extent can job satisfaction be explained as the revenue of social capital?” By conceiving someone’s social network as social capital we specify conditions under which social ties do lead to job satisfaction. We inquire into the idea of goal specificity of social capital, which implies that a network with a given structure and content will have different impacts on various aspects of job satisfaction. If the content of the ties and the structure of the network at the job engender material well-being or produce social approval, satisfaction with the corresponding job aspects increases. Data were collected in 1993 using written questionnaires in two Dutch governmental agencies, one with 32 and the other with 44 employees. These workers’ networks were charted using nine name-generating questions.Social capital, it turns out, is not an all-purpose good but one that is goal specific, even within a single domain of life such as work. Three effects stand out: First, the structure of the network and the content of the ties do matter. Networks of strategic, work-related ties promote an employee’s satisfaction with instrumental aspects of the job, like income, security, and career opportunities. Second, closed networks of identity-based solidarity ties improve an employee’s satisfaction with social aspects of the job, like the general social climate at work and cooperation with management and colleagues. Third, a network with a bow–tie structure (i.e., where a focal actor is the link between two or more mutually exclusive cliques) generally has strong negative effects on satisfaction with the social side of the job; although a bow–tie type network of trusting ties does increase satisfaction with the social side. This implies that Krackhardt’s hypothesis on the unpleasant feelings produced by bow–tie type networks has to be specified for the content of the ties that constitute such a network. The most important conclusion of our analysis is that goal specificity of social capital has implications for both structure and content of social networks. Achievement of a particular goal, such as satisfaction at work, requires not only networks of a certain structure or ties with a particular content, but specifically structured networks of ties with a particular content.     

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.     

Social network structure and the trade-off between social utility and economic performance

We put forward a computational multi-agent model capturing the impact of social network structure on individuals’ social trust, willingness to cooperate, social utility and economic performance. Social network structure is modeled as four distinct social capital dimensions: degree, centrality, bridging and bonding social capital. Model setup draws from socio-economic theory and empirical findings based on our novel survey dataset. Results include aggregate-level comparative statics and individual-level correlations. We find, inter alia, that societies that either are better connected, exhibit a lower frequency of local cliques, or have a smaller share of family-based cliques, record relatively better aggregate economic performance. As long as family ties are sufficiently valuable, there is a trade-off between aggregate social utility and economic performance, and small world networks are then socially optimal. We also find that in dense networks and trustful societies, there is a trade-off between individual social utility and economic performance; otherwise both outcomes are positively correlated in the cross section.     

Ambivalence in Later‐Life Family Networks: Beyond Intergenerational Dyads

In later life, changing conditions related to health, partnership, and economic status may trigger not only support but also conflict and ambivalence, with the consequent renegotiation of family ties. The aim of this study is to investigate both conflict and emotional support in the family networks of older adults, taking the research beyond the level of intergenerational dyads. We used a subsample of 563 elders (aged 65 years and older) from the Swiss Vivre/Leben/Vivere survey. Multiple correspondence analysis and in‐depth case studies were used to identify the key social conditions that relate to the prevalence of conflicted and supportive dyads in family networks. Findings showed that the balance of conflict and emotional support in older adults' family networks varied according to the composition of their family network as well as their age, health, income, and gender.     

Migrants' social networks and weak ties: accessing resources and constructing relationships post‐migration

Within migration studies literature there is a tendency to assume that migrants have ready access to kin and friendship networks which facilitate the migration and settling processes. Through tight bonds of trust and reciprocity, these networks are considered to be sources of social capital, providing a counter‐balance to the disadvantages that migrants may encounter in the destination society. This paper argues that more attention is needed to the ways in which migrants access, maintain and construct different types of networks, in varied social locations, with diverse people. I suggest that the often simplistic dichotomy of bonding and bridging capital needs to be re‐appraised and instead offer an alternative way of thinking about these social ties. The distinction between them tends to be understood on the basis of the ethnicity of the people involved – bonding involves close ties with ‘people like us’ while bridging involves links beyond ‘group cleavages’. Insufficient attention has been paid to the actual resources flowing between these ties or the kinds of relationship developing between the actors involved. The nature of these social networks may be better understood by focusing on the relationship between the actors, their relative social location, and their available and realisable resources. Data from a qualitative study of Polish migrants in London is used to illustrate this approach.     

Network domains in social networking sites: expectations,meanings, and social capital

This paper examines why the use of social networking sites (SNSs) leads to different results in cultivating bridging and bonding social capital for different groups of people. Based on in-depth interviews of 45 university students in Hong Kong, I find that Mainland Chinese students studying in Hong Kong actively use SNSs for seeking practical information about offline matters, and they obtain substantial enacted support from other Mainland students of the same university through SNS use. As a result, they accumulate both bridging and bonding social capital. Local Hong Kong students, however, use SNSs mainly for social information seeking and are only able to accrue limited bridging social capital through SNS use. Drawing on the theory of network domains, I argue that the different offline network structures in which students are located – namely, homogeneous and closed networks versus heterogeneous and open networks – explain this difference. Students with closed offline networks have defined expectations of online ties; they think of their online activities as practical and leading to real changes in their status among peers. Those with open networks have indefinite expectations of their online audience; thus, they interpret online activities differently, thinking of them as recreational, and they are playful in their online behaviour. These different outcomes of online activities consequently lead to diverse results in social capital accrual.     

The Social Relationships and Social Support of Aging Mothers Whose Adult Daughters Are Mentally Ill

Guided by a conceptual framework highlighting multiple facets of social relationships and social support, this study examined the extent to which aging mothers of adult daughters with a serious mental illness were socially integrated with members of their network. It further examined the relational content of these mothers’ social ties as tangible or intangible support and the nature of their supportive exchanges with network members, particularly their adult daughters with mental illness. A structured face-to-face interview was conducted with 22 aging mothers of these adult daughters. Two methods of analysis were used to analyze data: counting and content analysis. Findings showed aging mothers of daughters with mental illness were socially integrated with relatives and nonrelatives, evidenced relational content of tangible and intangible support in their social ties and engaged in bidirectional and asymmetrical support exchanges with network members, including their daughters with mental illness. These findings suggest that social resources in the form of social relationships and support are embedded in the networks of aging mothers who have adult daughters with serious mental illness. Practitioners should assess support contributions to the aging mothers of adult daughters with serious mental illness from a wide range of social relationships including their daughters.     

A network centrality bias: Central individuals in workplace networks have more supportive coworkers

Combining the results of two empirical studies, we investigate the role of alters’ motivation in explaining change in ego’s network position over time. People high in communal motives, who are prone to supportive and altruistic behavior in their interactions with others as a way to gain social acceptance, prefer to establish ties with co-workers occupying central positions in organizational social networks. This effect results in a systematic network centrality bias: The personal network of central individuals (individuals with many incoming ties from colleagues) is more likely to contain more supportive and altruistic people than the personal network of individuals who are less central (individuals with fewer incoming ties). This result opens the door to the possibility that the effects of centrality so frequently documented in empirical studies may be due, at least in part, to characteristics of the alters in an ego’s personal community, rather than to egos themselves. Our findings invite further empirical research on how alters’ motives affect the returns that people can reap from their personal networks in organizations.     

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.     

Social network resources and management of hypertension

Hypertension is one of the most prevalent chronic diseases among older adults, but rates of blood pressure control are low. In this article, we explore the role of social network ties and network-based resources (e.g., information and support) in hypertension diagnosis and management. We use data from the National Social Life, Health, and Aging Project to identify older adults with undiagnosed or uncontrolled hypertension. We find that network characteristics and emotional support are associated with hypertension diagnosis and control. Importantly, the risks of undiagnosed and uncontrolled hypertension are lower among those with larger social networks-if they discuss health issues with their network members. When these lines of communication are closed, network size is associated with greater risk for undiagnosed and uncontrolled hypertension. Health care utilization partially mediates associations with diagnosis, but the benefits of network resources for hypertension control do not seem to stem from health-related behaviors.     

Networks in lockdown: The consequences of COVID-19 for social relationships and feelings of loneliness

This paper studies social network changes during the COVID-19 crisis in the Netherlands and their relation to perceived loneliness for the younger and the older cohorts. Arguments from opportunity theory and social capital theory are used to formulate hypotheses on network changes during the pandemic. Core discussion networks and networks with practical helpers from two representative cohorts (18–35 years of age and 65+ years of age, n = 1342 participants in both waves) during the lockdown in May 2020 are compared with networks of the same respondents in May 2019. We find that networks became smaller and more focused on stronger ties, while weaker ties more often decayed. Feelings of loneliness incsreased on average for all respondents and in particular for those who live alone or have a disadvantaged socioeconomic position. Importantly, the decrease in the number of the practical helper network, that is, decline in relatively weaker ties, affects experiences of loneliness in both groups.     

A relational analysis of migration in old age: How transnational ties affect migration decisions

Recently, the role of personal ties in migration decisions has received considerable attention. However, this aspect has seldom been studied in the context of retirement. This paper addresses this gap by shedding light on the composition of personal networks, types of mobility patterns and retirement locations for four groups of older adults. To this end, two methodological approaches are employed: (1) a qualitative Social Network Analysis to examine the composition of older adults' personal networks and (2) thematic coding to analyse the relational aspects of migration decisions. This paper draws on 29 semi-structured interviews conducted in Spain and Switzerland in 2020 and 2021. The findings demonstrate that pre-retirement migration trajectories shape personal network composition. Moreover, personal ties play a critical role in older adults' mobility patterns and choices of retirement location. Overall, this study provides valuable insights into the impact of personal networks on migration decisions of older adults.     

Community Connections: Social Capital and Community Success1

This article examines the impact of two types of community social capital—ties between civic organizations formed through shared members and ties between residents formed through socializing in local gathering places—on residents’ subjective appraisals of community success. Community social capital studies tend to focus on the first of these types of ties, networks of civic engagement, while the second, gathering place networks, has received relatively little scholarly attention. Studying both allows me to assess the formal and informal arenas of community sociability, providing a more thorough understanding of social capital and community life. I assess the effects of community‐level social capital networks on the individual‐level experience of residing in the community using survey data on 9,962 residents from 99 small towns in Iowa. This rich data set allows me to avoid two shortcomings common in social capital research: I construct genuine network measures of social capital (rather than infer network structure from community attributes) and conduct multi‐level analyses (rather than rely on disaggregation). My findings indicate both types of social capital are positively and significantly associated with resident ratings of community success, suggesting community networks—in both the formal and informal sectors—have important consequences for small towns and their residents.     

Extrapolative simulation of neighborhood networks based on population spatial distribution: Do they predict crime?

Objectives

Previous criminological scholarship has posited that network ties among neighborhood residents may impact crime rates, but has done little to consider the specific ways in which network structure may enhance or inhibit criminal activity. A lack of data on social ties has arguably led to this state of affairs. We propose to avoid this limitation by demonstrating a novel approach of extrapolatively simulating network ties and constructing structural network measures to assess their effect on neighborhood crime rates.

Methods

We first spatially locate the households of a city into their constituent blocks. Then, we employ spatial interaction functions based on prior empirical work and simulate a network of social ties among these residents. From this simulated network, we compute network statistics that more appropriately capture the notions of cohesion and information diffusion that underlie theories of networks and crime.

Results

We show that these network statistics are robust predictors of the levels of crime in five separate cities (above standard controls) at the very micro geographic level of blocks and block groups.

Conclusions

We conclude by considering extensions of the approach that account for homophily in the formation of network ties.     

Bridging ties at the neighborhood level

This paper examines the relevance of the “strength of weak ties” model (Granovetter 1973) in devising community development strategies for urban neighborhoods. The policy implications of this model for activities designed to promote neighborhood identification and cohesion are outlined, and Granovetter's specific assumptions about the structure and functioning of urban neighborhood social networks are assessed in light of existing research. Little support is found for the presumed absence of bridging weak ties among urban neighbors, or for the assumption that strong ties create an obstacle to effective political mobilization in working-class neighborhoods. An alternative model of local-level integration is suggested, which retains Granovetter's concept of dense clusters of network ties linked by “local bridges”, but re-examines the role of weak ties in effecting such bridges.     

The social networks of new-generation migrants in China’s urbanized villages: A case study of Guangzhou

The integration of rural migrants into China’s urban society has drawn extensive attention in recent years. There are, however, a growing number of new-generation migrants whose prospects of integration cannot be gleaned from the experience of their predecessors—the old-generation migrants. The reconstruction of migrant network is a lens through which one can examine the extent and pattern of their integration. In this paper, using quantitative data derived from a survey of eight urbanized villages in Guangzhou, we examine the socio-spatial pattern of migrant networks and the role of receiving neighborhoods in social interactions, with a focus on inter-generational differences. The findings show that new-generation migrants are more likely to draw on cross-class, non-kin, and non-territorial networks when seeking social support, but that hometown-based bonds and the urbanite-migrant divisions remain central to their social networks. For the role of receiving neighborhoods, although new-generation migrants have weak neighborly interactions, they construct numerous colleagues and friendship ties that transcend the boundaries of neighborhoods. Moreover, educational attainment, income level, and occupation structure are important determinants of the nature of new-generation migrant networks. The results suggest that generational factors should be highly considered when studying the integration of migrants into Chinese urban society. Accordingly, the integration of migrants into the urban society will be a conflictual and contradictory process.     

Moving Through Social Networks: The Case of Armenian Migrants in the Czech Republic

This paper brings attention to the role of social networks in the migration of asylum seekers and explores how the embeddedness of the migrants in social networks both facilitates and constrains their mobility in different phases of the migration process. It reconstructs the migration paths of eight Armenian migrant families who arrived in the Czech Republic as asylum seekers during the 1990s and the beginning of the twenty‐first century. By examining the narrated stories of the Armenian migrants it shows that social networks formed an important context for employing various migration strategies in all phases of the migration process, and that the meaning and character of migrants’ social networks changed over time. In the initial phase of decision‐making about migration as well as on their journey, it was mainly weak ties of random acquaintances that played a dominant role. The position of the migrants in those networks was rather insecure. They held a little control over the information they received, but in these vulnerable situations they had to rely on their weak ties, which strongly influenced their mobility. In the arrival and settlement phases the social context of the refugee camp hindered the cultivation of social ties outside the migrants’ circle on one hand, and facilitated development of bonding ties among the migrants on the other. Bonding social networks enabled inclusion of the Armenian migrants into various social spheres especially at the beginning of the settlement process. However, the bounded character of these networks was also recognized as excluding them from access to resources of the dominant society and preventing their social mobility in later phases of their settlement. Thus, bridging networks that provide access to certain resources of the dominant society were sought.
