Unravelling SW industry trading networks: The role of reciprocity, transitivity, and firm characteristics
In today’s digital economy, the software (SW) industry acts as a core engine of technological progress and competitiveness. Rather than simple transactions, trading networks amongst SW firms generate complex interdependencies that shape market behaviour, innovation diffusion, and firm-level opportunities. This study applies the Exponential Random Graph Model to Korean SW transaction data, integrating firm-level attributes with structural features…
Dyadic Appraisals of Family Decisions and Health Tasks in Midlife-Older Couples
Shared appraisals and collaboration within couples play important roles in optimizing health. Less is known about concordance regarding collaboration, factors associated with concordance, and implications for health. Data from 2,761 couples from the Health and Retirement Study (2014/2016 and 2016/2018 waves) were examined to determine within-couple concordance in completion of two tasks (family decisions and medical forms). The majority of couple…
Social Activities With Friends and Neighbors in Relation to Cognitive Function in Later Life: The Benefits of Contact and Helping
Despite a growing body of literature linking social activities to cognitive function, studies specifically examining the potential cognitive benefits of friendships and neighbors remain limited. Drawing on eight waves of nationally representative data from the Health and Retirement Study (1998–2012; N = 29,777), we investigated whether two distinct forms of social activities with friends and neighbors—(1) getting together for a social visit and (…
Helping behaviors and cognitive function in later life: The impact of dynamic role transitions and dose changes
Evaluating the Efficiency of Social Conflict Management Based on the Institutional Capacity of the Government: A Cross-National Approach
Heterogeneous Effects of Volunteering on Frailty in Later Life: A Panel Quantile Regression Approach
The current study findings provide unique and compelling evidence in support of earlier calls for considering volunteering as a public health intervention. The study findings are discussed in the context of population health outcomes and health disparities
Introduction to the Special Issue on Productive Aging in Honor of Frank Caro
Neighborhood Cohesion Across the Life Course and Effects on Cognitive Aging
Findings provide insight into life-course neighborhood contextual influences on cognitive aging. Our results emphasize the need for more research to understand the life-course dynamics between neighborhood environments and cognitive aging
Psychological and Physical Health in Widowhood: Does Marital Quality Make a Difference
We investigate how preloss marital quality is associated with changes in psychological distress and physical health among older widow(er)s. Using prospective data with a 2-year follow-up from the Health and Retirement Study, we selected 546 respondents who transitioned into widowhood. Respondents were classified as supportive, ambivalent, aversive, or neutral groups. The supportive and ambivalent group experienced greater increase in depressive s…
Adult children's achievements and ageing parents’ depressive symptoms in China
This study examined the association between adult children's achievements and ageing parents’ depressive symptoms in China. The research topic was examined within the contexts of one-child and multiple-children families in rural and urban China. Older adults (aged 60–113, N = 8,450; nested within 462 communities/villages) from the 2013 China Longitudinal Ageing Social Survey provided information about themselves and their adult children ( N = 22,…
Age and Cohort Trends in Formal Volunteering and Informal Helping in Later Life: Evidence From the Health and Retirement Study
Formal volunteering holds great importance for the recipients of volunteer services, individuals who volunteer, and the wider society. However, how much recent birth cohorts volunteer in middle and late adulthood compared with earlier birth cohorts is not well understood. Even less well-known are the age and cohort trends in informal helping provided to friends and neighbors in later adulthood. Using longitudinal data from the Health and Retireme…
The Impact of Marital Quality as Older Couples Adjust to Dementia Onset
This study adds to the literature by showing how discrepant marital assessments shape cognitive aging and offers new insights into identifying older adults with greater dementia risk. Findings also revealed the impact of overall negative marital quality on older adults' psychological adjustment to spousal dementia, which could inform interventions intended to help couples better cope with early-stage dementia from a relational perspective
Older Adult’s Marital Status, Conversation Frequency, and Well-Being in Everyday Life
Findings highlight the role of marital status in older adults' daily conversational experiences and compensatory processes that may occur. Widowed and divorced older adults differed from married older adults in distinct ways. Divorced older adults may compensate for lack of spouse with friends, whereas widowed older adults may benefit emotionally from engaging in conversations
Health consequences of retirement due to non-health reasons or poor health
Take a sad song and make it better: Spousal activity limitations, caregiving, and depressive symptoms among couples
Volunteering, polygenic risk for Alzheimer's disease, and cognitive functioning among older adults
Functional Limitations, Volunteering, and Diurnal Cortisol Patterns in Older Adults
This study advances our understanding of functional limitations and cortisol stress responses, revealing the benefits of volunteering to older adults who experience these limitations. Rather than treating these older adults solely as care recipients, interventions should offer them opportunities to help others
Edentulism and Trajectories of Cognitive Functioning Among Older Adults: The Role of Dental Care Service Utilization
Objective: This study examined the associations between edentulism, dental care service utilization, and cognitive functioning trajectories among older adults. Method: Longitudinal data from the Health and Retirement Study (2006-2014) were employed to examine individuals aged 51 and older who were identified as having normal cognition at baseline ( N = 12,405). Cognitive functioning was measured with a modified version of the Telephone Interview …
Activity Limitations and Depressive Symptoms Among Older Couples: The Moderating Role of Spousal Care
Receipt and provision of activities of daily living-related assistance may contextualize the association between activity limitations and depressive symptoms among older coupled-individuals in a direction that could alleviate or aggravate the risk of depression
Stress-Buffering Effects of Volunteering on Daily Well-Being: Evidence From the National Study of Daily Experiences
Our findings suggested that the stress-buffering effect of volunteering contributes to improved emotional well-being for participants who volunteered on a daily basis. Future studies should investigate whether such stress-buffering effects are present for other forms of helping behaviors
Stress-buffering effects of volunteering on salivary cortisol: Results from a daily diary study
Friendship and Depression Among Couples in Later Life: The Moderating Effects of Marital Quality
Friendship is an important contributor to individuals' mental health in later life, with its benefits having far-reaching consequences for one's significant other. The implications of friendship interactions for other health domains also require investigation within the marital context
Health Benefits Associated With Three Helping Behaviors: Evidence for Incident Cardiovascular Disease
The results demonstrated that specific types of prosocial behavior may be beneficial for women and men. However, tests for effect differences showed that gender did not moderate the relationships between these helping behaviors and CVD risk
Social Activities, Incident Cardiovascular Disease, and Mortality: Health Behaviors Mediation
Social activity is a modifiable behavior that may be considered a potential health intervention
