Abstract We analyze the causal effect of retirement on individual social relationships using data from Survey Health, Ageing and Retirement in Europe. find that changes composition individual’s network, inducing a substitution between weak (friends or colleagues) strong ties (family), along with an increase intensity surviving ties, there is no network’s size. These are associated higher satisf...

We examine data on and models of small world properties and parameters of social networks. Our focus, on tie-strength, multilevel networks and searchability in strong-tie social networks, allows us to extend some of the questions and findings of recent research and the fit of small world models to sociological and anthropological data on human communities. We offer a ‘navigability of strong tie...

Studies investigating the impact of combining paid work and family life on wellbeing have generally used information at one or a limited number of points in the life course, and have mainly focused on women. This study uses multi-channel sequence analysis to characterise work-family life courses across adulthood (ages 16-60) for more than 1500 men and women in the MRC National Study of Health a...

Abstract Research on social networks of immigrants and their descendants usually starts from the distinction between ‘ethnic’ ties to members population without migration background. In studies are repeatedly associated with ‘strong ties’, whereas ‘weak ties’ – that found be essential for access jobs in wider society contacts ‘majority population’. Building existing criticism this narrowing dic...

Social networks play an important role in our daily lives. However, social ties are rather elusive to quantify, especially for large groups of subjects over prolonged periods of time. In this work, we first propose a methodology for extracting social ties from long spatio-temporal data streams, where the subjects are 17,795 undergraduates from a university of China and the data streams are the ...

In group-living species, individuals often have preferred affiliative social partners, with whom ties or bonds can confer advantages that correspond with greater fitness. For example, in adult female baboons and juvenile horses, individuals with stronger or more social ties experience greater survival. We used detailed behavioral and life history records to explore the relationship between tie ...

Ethnic Networks and Employment Outcomes We analyse the effect of strong and weak ties on the individual probability of finding a job. Using the dynamic model of Calvó-Armengol and Jackson (2004), two results are put forward: (i) the individual probability of finding a job is increasing in the number of strong and weak ties; (ii) the longer the length of ties, the lower is this effect. We approx...

Diversity in social relations is important for reducing prejudice. Yet, the question of when this occurs remains open. Using a network approach, we test whether link between outgroup attitudes and number intra- intergroup contacts moderated by type relationship (strong vs. weak ties) personality (openness to experience) while also considering structure (connections contacts). In culturally dive...

I construct a model where upstream income transfers, from adult children to their old parents, are driven by culture of strong family ties. This evolves endogenously, through process intergenerational cultural transmission. The two-way causal link between economic and change can be enough force offset substitution, thus generating path-dependent outcomes. These outcomes show that development is...
