Few studies have examined the relationship between social networks and colorectal cancer screening in diverse populations. Prior research suggests that the type of social support as well as the amount or frequency of support available from one's social network may be associated with health outcomes. Therefore, the current study examined relationships between both structural (i.e., quantitative ...

The effect of weather on social interactions has been explored through the analysis of a large mobile phone use dataset. Time spent on phone calls, numbers of connected social ties, and tie strength were used as proxies for social interactions; while weather conditions were characterized in terms of temperature, relative humidity, air pressure, and wind speed. Our results are based on the analy...

In this paper we will examine the role of embeddedness and social capital in the process of cohesive subgroup formation in strategic technology alliance networks. More in particular, we will investigate the social mechanisms that enable and enforce cohesive subgroup formation. We will argue that the enabling effects of social capital in the beginning of the group formation process can turn into...

As a social media, online social networks play a vital role in the social information diffusion. However, due to its unique complexity, the mechanism of the diffusion in online social networks is different from the ones in other types of networks and remains unclear to us. Meanwhile, few works have been done to reveal the coupled dynamics of both the structure and the diffusion of online social...

Older adults consistently report having fewer close and fewer problematic social ties than do younger adults. Yet, prior studies have not explicitly examined associations between the availability of living relatives and the nature of family ties in later life. One hundred sixty-four individuals ages 13 to 99 described their networks of close and problematic social ties. Then they provided infor...

The logic of the so-called “social distancing” has highlighted vulnerability immigrants, especially those Haitian origin. Facing this, through qualitative methodology, relationship between measures decreed in face pandemic, a political-social crisis that precedes it, informal labor, and precarious housing, is explored, since these points are key to understanding formation unique habitat, ties, ...

Weak ties are thought to facilitate the diffusion of information through social networks because of their tendency to span otherwise distant subgroups. However, this logic assumes that weak relationships have the same capacity to transmit information as those that are strong. I argue that weak ties, especially the kind that span subgroups, are often also lower-capacity. Due to a lack of trust, ...

Previous literature has shown that interorganizational networks tend to be stable, but evidence of that stability stems from analysis showing that existing network structure reinforces itself through the formation of new ties. However, discontinuation of existing ties also affects the degree of network stability. If the same factors that lead to tie replication also lead to tie dissolution, the...
