Personal networks undergo change in response to major life course events. Individual, relational, and network characteristics that influence network instability in the absence of a significant life transition/crisis are less understood. We focus on those ties that transition from active to dormant. Because the shift to dormancy is often interpreted as a reduction in support or social capital, it is considered problematic. This study is based on longitudinal survey data of middle‐class adults who did not undergo life changes. Even in this context of relative stability, support networks experience rates of dormancy similar to those observed during periods of major upheaval. Tie dormancy is unrelated to individual characteristics, network size and density, or homophily along dimensions other than sex. Frequency and medium of communication are particularly notable as factors that were not related to tie dormancy. Ties were less likely to become dormant if they were geographically or emotionally close, immediate kin or neighbors, highly supportive, the same sex, or more embedded in the network. These findings provide context for how support networks operate when not buffeted by exogenous forces. They provide a baseline for understanding the impact on networks of transitions, trauma, new media, and difficult life circumstances. [ABSTRACT FROM AUTHOR]

Existing research suggests that social media use is associated with higher levels of social capital—the resources contained within a person’s network of friends, family, and other acquaintances. However, in predicting access to these resources, it has been impossible to distinguish the affordances of social media from the underlying advantage of maintaining a favorable social network of relationships on- and offline. Based on data from a representative, national survey, we compare the relationship between social network structure and various activities on Facebook for one type of resource: informal social support in the form of companionship, emotional support, and tangible aid. In addition to a positive association between number of close ties, overall network size and diversity and social support, we find that Facebook status updates and private messaging are independently associated with perceived support. We argue that these affordances are an outcome of the “pervasive awareness” provided by social media. [ABSTRACT FROM AUTHOR]

Two affordances of digital communication technologies, persistent contact and pervasive awareness, are ushering in fundamental change to the structure of community. These affordances break from the mobility narrative that has described community since the rise of urban industrialism, including accounts of networked individualism and a postindustrial or a network society. In contrast to images of late modernity, which suggest that mobility will be maximized to the point where people are nearly free from the constraints of time, space, and social bonds, persistent–pervasive community renews the constraints and opportunities of premodern community structure. As a result of persistence—a counterforce to mobility—relationships and the social contexts where they are formed are less transitory than at any time in modern history. Through the ambient, lean, asynchronous nature of social media, awareness supplements surveillance with the informal watchfulness typified in preindustrial community. It provides for closeness and information exchange unlike what can be communicated through other channels. Social media and the algorithms behind them generate not only context collapse but an audience problem that, when managed through a dynamic balance between broadcasting and monitoring content, enhances indicators of awareness and availability of social ties. Persistent–pervasive community represents a period of metamodernity. It is a hybrid of preindustrial and urban-industrial community structures that will affect the availability of social capital, the success of collective action, the cost of caring, deliberation around important issues, and how lives are linked over the life course and across generations.

The structure of people's social networks predicts democratic engagement. However, the relative contribution of different types of social ties to civic and civil behaviors is unclear. This paper explores the role of core networks - bonding social capital - to the role of overall network diversity - bridging social capital - for participation in formal civic institutions and informal civil behaviors. Emphasis is placed on the possible role of heterogeneity within core networks - political disagreement and the presence of nonkin ties - and on frequency of interaction, in-person and mediated: mobile phone and the Internet. This study finds that overall network diversity is a more consistent and substantive predictor of civic and civil behaviors than the size or heterogeneity of the small number of ties that make up the core network of most people. The two dominant new media used to interact with core network members - email and mobile phones - are unrelated to any of the behaviors measured. Some other media - contact in-person, postal mail, texting, instant messaging, and social network services - have an inconsistent and modest relationship to civic and civil behaviors. Findings lead to speculation that political disagreement within core networks, typically associated with lower levels of political participation, has a spillover effect that results in other forms of democratic engagement. There is evidence of glocalization; contact with core ties using new media supports local civil and civic behaviors. Internet use largely supports democratic engagement through interaction with bridging, but not bonding ties. [ABSTRACT FROM AUTHOR]

This study examines the relationship between mode of Internet access, variety of online activities, and the potential for the Internet to contribute to local social capital in distressed, urban communities. Based on a sample of 525 telephone surveys in Detroit, findings show that breadth of access predicts participation in a larger variety of online activities, which is associated with higher levels of local social capital. Neither public Internet access, home broadband, nor Internet access through a mobile phone data plan alone affords participation in a full range of social capital-enhancing activities. The findings highlight the potential problems of initiatives that assume equivalent social outcomes through nonequivalent modes of access, such as providing Internet access through mobile phones in place of home broadband. Efforts to enhance a city's social infrastructure by providing Internet access are best served when individuals have multiple points of access available. [ABSTRACT FROM AUTHOR]
