Disability and social ties: comparative findings of the CLESA study.

ABSTRACT: The associations between prevalence, incidence and recovery from activities of daily living (ADL) disability and social ties among community-dwelling persons over 65 in Finland, The Netherlands and Spain are examined. Data were harmonized in the CLESA study. The baseline sample was composed of 3,648 subjects between 65 and 85 years old, living in Finland, The Netherlands and Spain. Disability in four activities of daily living was determined at baseline and at follow-up. Social participation, number of family ties and presence of friends were added to obtain a social ties index. Logistic regressions were fitted to the prevalence, incidence and recovery data to estimate the associations between disability and social ties, adjusting for education, co-morbidity and self-rated health. The modifying effects of country, age and sex were tested in all models. For every country, the social ties index, having friends and social participation were negatively associated with ADL disability prevalence. ADL incidence was negatively related to the number of family ties, with a stronger relationship in Spain than in The Netherlands or Finland. ADL recovery was associated with the social ties index. No age or gender differences in these associations were found. Social ties appear to generate a beneficial effect on the maintenance and restoration of ADL function. While social ties play an important role in maintaining and restoring function in all three countries, family ties appear to generate a stronger effect on protection from disability incidence than does social participation, and the strength of this effect varies by culture.

Coupling human mobility and social ties.

Project description:Studies using massive, passively collected data from communication technologies have revealed many ubiquitous aspects of social networks, helping us understand and model social media, information diffusion and organizational dynamics. More recently, these data have come tagged with geographical information, enabling studies of human mobility patterns and the science of cities. We combine these two pursuits and uncover reproducible mobility patterns among social contacts. First, we introduce measures of mobility similarity and predictability and measure them for populations of users in three large urban areas. We find individuals' visitations patterns are far more similar to and predictable by social contacts than strangers and that these measures are positively correlated with tie strength. Unsupervised clustering of hourly variations in mobility similarity identifies three categories of social ties and suggests geography is an important feature to contextualize social relationships. We find that the composition of a user's ego network in terms of the type of contacts they keep is correlated with mobility behaviour. Finally, we extend a popular mobility model to include movement choices based on social contacts and compare its ability to reproduce empirical measurements with two additional models of mobility.

The structured backbone of temporal social ties.

Project description:In many data sets, information on the structure and temporality of a system coexists with noise and non-essential elements. In networked systems for instance, some edges might be non-essential or exist only by chance. Filtering them out and extracting a set of relevant connections is a non-trivial task. Moreover, mehods put forward until now do not deal with time-resolved network data, which have become increasingly available. Here we develop a method for filtering temporal network data, by defining an adequate temporal null model that allows us to identify pairs of nodes having more interactions than expected given their activities: the significant ties. Moreover, our method can assign a significance to complex structures such as triads of simultaneous interactions, an impossible task for methods based on static representations. Our results hint at ways to represent temporal networks for use in data-driven models.

Social ties influence teamwork when managing clinical emergencies.

Project description:BACKGROUND:Our current understanding of medical team competence is traditionally influenced by an individualistic perspective focusing on individual team members' knowledge, skills as well as on effective communication within the team. However, team dynamics may influence team performance more than previously anticipated. In particular, recent studies in other academic disciplines suggest that social ties between team members may impact team dynamics but this has not been explored for medical teams. We aimed to explore intensive care staff's perceptions about teamwork and performance in clinical emergencies focusing particularly on the teams' social ties. METHODS:Semi-structured interviews were conducted with a purposive sample of intensive care staff. We used a thematic analysis approach to data interpretation. RESULTS:Thematic saturation was achieved after three group interviews and eight individual interviews. Findings demonstrated that social ties influenced teamwork by affecting the teams' ability to co-construct knowledge, coordinate tasks, the need for hierarchy, the degree to which they relied on explicit or implicit communication, as well as their ability to promote adaptive behavior. CONCLUSIONS:Social ties may be an important factor to consider and acknowledge in the design of future team training, as well as for work planning and scheduling of team activities during clinical practice. More research is needed into the causal effect of social ties on team performance and outcome.

Empathy and Close Social Ties in Late Life.

Project description:ObjectivesOlder adults with stronger social ties often lead longer, healthier, and happier lives, but these ties may differ based on older adults' ability to share and understand others' emotions (i.e., empathy). This study asked how empathy was associated with the way that older adults construct and engage in their social worlds.MethodWe drew on the Daily Experiences and Well-being Study to examine how older adults' empathy was associated with the structure (e.g., network size and contact), function (e.g., support), and quality (e.g., affection and conflict) of their close social ties. Participants (N = 333) self-rated empathy and listed their social partners using three concentric convoy circles.ResultsEmpathy was not associated with older adults' social network structure, but more empathic older adults exchanged support with more social partners and reported greater affection for their social partners. We did not observe a significant link between older adults' empathy and conflict with social partners.DiscussionExamining empathy advances our understanding of individual differences in older adults' close social ties. This study suggests that empathy may play a promising role with regard to promoting older adults' social experiences and strengthening their close ties.

Local Ties in the Social Networks of Older Adults.

Project description:ObjectivesFamily members and friends who live nearby may be especially well-positioned to provide social support and companionship for community-residing older adults, but prior research has not examined the distribution and characteristics of local ties in older adults' networks. We hypothesize that local ties are newer, more frequently accessed, and more embedded in the network, and that social disadvantage and neighborhood conditions structure older adults' access to local ties.MethodsWe use egocentric network data from 15,137 alters named by 3,735 older adults in Wave 3 of the National Social Life, Health, and Aging Project (NSHAP). We conduct dyadic analysis to compare characteristics of local and nonlocal ties. Logistic regression models estimate how personal and neighborhood characteristics are associated with naming local kin and local non-kin ties.ResultsNearly half of the older adults named at least one local network tie, and about 60% of these local ties are non-kin. Local ties are newer, frequently accessed, and highly embedded in older adults' networks. Local kin ties are most common among socially disadvantaged older adults. Local non-kin ties are most common among white older adults and those who live in areas with high levels of collective efficacy, although local non-kin ties are also associated with residence in high-poverty neighborhoods.DiscussionLocal ties may bring unique benefits for community-residing older adults, but their availability is likely structured by residential mobility, neighborhood context, disparities in resources, and support needs. Future research should consider their implications for health and well-being.

The Structure of Negative Social Ties in Rural Village Networks.

Project description:Negative (antagonistic) connections have been of longstanding theoretical importance for social structure. In a population of 24,696 adults interacting face to face within 176 isolated villages in western Honduras, we measured all connections that were present, amounting to 105,175 positive and 16,448 negative ties. Here, we show that negative and positive ties exhibit many of the same structural characteristics. We then develop a complete taxonomy of all 138 possible triads of two-type relationships. Consistent with balance theory, we find that antagonists of friends and friends of antagonists tend to be antagonists; but, in an important empirical refutation of balance theory, we find that antagonists of antagonists also tend to be antagonists, not friends. Finally, villages with comparable levels of animosity tend to be geographically proximate. Similar processes, involving social contact, give rise to both positive and negative social ties in rural villages, and negative ties play an important role in social structure.

Quality versus quantity of social ties in experimental cooperative networks.

Project description:Recent studies suggest that allowing individuals to choose their partners can help to maintain cooperation in human social networks; this behaviour can supplement behavioural reciprocity, whereby humans are influenced to cooperate by peer pressure. However, it is unknown how the rate of forming and breaking social ties affects our capacity to cooperate. Here we use a series of online experiments involving 1,529 unique participants embedded in 90 experimental networks, to show that there is a 'Goldilocks' effect of network dynamism on cooperation. When the rate of change in social ties is too low, subjects choose to have many ties, even if they attach to defectors. When the rate is too high, cooperators cannot detach from defectors as much as defectors re-attach and, hence, subjects resort to behavioural reciprocity and switch their behaviour to defection. Optimal levels of cooperation are achieved at intermediate levels of change in social ties.

Social features of online networks: the strength of intermediary ties in online social media.

Project description:An increasing fraction of today's social interactions occur using online social media as communication channels. Recent worldwide events, such as social movements in Spain or revolts in the Middle East, highlight their capacity to boost people's coordination. Online networks display in general a rich internal structure where users can choose among different types and intensity of interactions. Despite this, there are still open questions regarding the social value of online interactions. For example, the existence of users with millions of online friends sheds doubts on the relevance of these relations. In this work, we focus on Twitter, one of the most popular online social networks, and find that the network formed by the basic type of connections is organized in groups. The activity of the users conforms to the landscape determined by such groups. Furthermore, Twitter's distinction between different types of interactions allows us to establish a parallelism between online and offline social networks: personal interactions are more likely to occur on internal links to the groups (the weakness of strong ties); events transmitting new information go preferentially through links connecting different groups (the strength of weak ties) or even more through links connecting to users belonging to several groups that act as brokers (the strength of intermediary ties).

Is social cohesion produced by weak ties or by multiplex ties? Rival hypotheses regarding leader networks in urban community settings.

Project description:In his seminal work, Mark Granovetter (1973) challenged sociologists to test sociometric hypotheses regarding collective action in communitarian settings. In this article, we tested the two main hypotheses which consider social cohesion in communitarian urban settings-these being firstly cohesion by weak ties and secondly cohesion by multiplex ties. We studied the elite leaders of two slum communities of Belo Horizonte (Brazil). Three social processes were examined as multiplex interactions: recognized status, exchange of useful information and collaboration. Our findings reveal, on the one hand, that multiplexity is associated with the frequency of ties and, on the other, that reciprocity and shared domains of performance fuel such strong multiplexity. If we assume that elite connections conform to a high order structure, our findings, in contrast to previously well-established hypotheses, reveal a segmented social order in which multiplexity does not mean the overlapping of social circles. On the contrary, multiplexed social exchanges are restricted to specialized domains.

Group-level cooperation in chimpanzees is shaped by strong social ties.

Project description:Humans maintain extensive social ties of varying preferences, providing a range of opportunities for beneficial cooperative exchange that may promote collective action and our unique capacity for large-scale cooperation. Similarly, non-human animals maintain differentiated social relationships that promote dyadic cooperative exchange, but their link to cooperative collective action is little known. Here, we investigate the influence of social relationship properties on male and female chimpanzee participations in a costly form of group action, intergroup encounters. We find that intergroup encounter participation increases with a greater number of other participants as well as when participants are maternal kin or social bond partners, and that these effects are independent from one another and from the likelihood to associate with certain partners. Together, strong social relationships between kin and non-kin facilitate group-level cooperation in one of our closest living relatives, suggesting that social bonds may be integral to the evolution of cooperation in our own species.
