Personal network dynamics across the life course: A relationship-related structural approach

Parental support and diversity in sibling personality

Personality is associated with important life outcomes such as occupational status, and there is continued interest in understanding how family processes shape people's character. Previous research has shown that despite being exposed to a common family environment, sibling personalities differ substantially. We test one explanation of this phenomenon: differential parental support within families. Fitting family fixed-effects models to data from the German Socio-economic Panel (SOEP), we find that, even within families, differences in parental support contribute to explain the personality of adolescent children. However, this association declines when children reach early adulthood. We interpret these results as demonstrating the importance of within-family factors for shaping personality, and how the influence of parent-child relationships varies over the life course.

The mechanisms of social network on subjective well-being from a life course perspective: the mediating role of individual resilience

BACKGROUND

Social networks are an important factor affecting Chinese residents' subjective well-being (SWB). Dividing social networks from the functional perspective can elucidate the SWB effect more effectively. This paper aims to explore how different social network supports affect SWB, further analyze the mechanism of individual resilience between them, and observe its changing trend throughout life.

METHODS

Based on the 2016 China Labor Dynamics Survey data (CLDS), this paper constructs an indicator system of individual resilience and, from the functional perspective, divides social networks into instrumental and emotional functions (SNI and SNE). According to age and the sequence of major life events, classify age groups as the operational variables of life course. The mediating effect and moderated mediating effect are the main models.

RESULTS

First, different types of social support in social networks are significant predictors of SWB. Among them, SNI has a greater effect on SWB than SNE and remains stable throughout life. Second, individual resilience is vital to SWB, and its effect does not vary throughout life. Third, individual resilience mediates between social networks and SWB, and its mediating effect increases over life.

CONCLUSIONS

The theoretical implications of developing social network measurement from a functional perspective and policy implications of focusing on the social support function of social networks and preventing it from disrupting social resource allocation rules are proposed.

Networked lives: Probing the influence of social networks on the life course

Social network research is well-equipped to help life course scholars produce a deeper and more nuanced approach to the principle of "linked lives," one of the cornerstones of the field. In this issue on Networked Lives, nine original articles and two commentaries generate new theories, empirical findings and methodological applications at the intersection of the fields of social networks and life course research. In this introduction, we reflect on these advances, highlighting key findings and challenges that await scholars in building more robust synergy between the two fields. Social networks emerge as key structural forces in life courses, yet there is much to learn about the mechanisms through which their effects on people's lives come about. There is a need to study further how networks evolve through the rhythm of life events, and to analyze broader and more complex networks that capture the roles and influences of relations beyond intimate or family ties. These papers demonstrate that there is much to be gained in probing how individuals are linked to and unlinked from others over time, and in carrying conceptual and methodological advances across social network and life course studies.

"Unlinked lives": Elaboration of a concept and its significance for the life course

This article introduces the concept of "unlinked lives" and illustrates its significance for scholarship on the life course. There are many lessons to be learned about human interdependence by focusing not on relationships that are formed and then maintained, but instead on relationships that are lost or ended by choice or circumstance, such as through changes in institutional affiliations, social status and positions or places. Unlinked lives carry important social meanings, are embedded in complex social processes, and bring consequences for the wellbeing of individuals, families, and societies. To develop this concept, we put forward nine key propositions related to when and how unlinkings happen as processes, as well as some of the consequences of being unlinked as a status or outcome. The coupling of "unlinked lives" with "linked lives" offers a crucial avenue for advancing life course theories and research, integrating scholarship across multiple life periods and transitions, and bridging the two now-distinct traditions of intellectual inquiry on the life course and on social networks.

Interconnected social convoys: Understanding health and well-being through linked personal networks

The convoy model of social relations describes how social relationships contribute to an individual's health and well-being from a life course and lifespan perspective. In large part, this model focuses on the unique, personal experiences of an individual, without due consideration of the reciprocal and shared relationships among those whose lives are inextricably linked. Here, we extend the convoy model to directly integrate Elder's concept of linked lives by considering the composition, structure, and function of linked personal networks, or social convoys, among close others, and the important implications of these network characteristics on the health of all involved. We illustrate this extension within the context of family, one of the most pivotal social contexts that can shape an individual's life course. Features of interconnected social convoys can help improve our understanding of how social ties shape and are shaped by life events not just for individuals, but for larger units of inquiry - such as, couples, parent-child triads, and nuclear families. Importantly, the interconnected convoy includes both family and non-family ties, providing a framework that considers how peoples' social spheres are linked as they jointly experience shared situations. Using informal caregiving as an example, we highlight the advantages that interconnected convoys bring to the concept of linked lives and provide direction on how this framework can advance our understanding of how social relationships influence either directly or indirectly health and well-being of individuals and families across the life course.
