Studies have shown how generativity, the concern for establishing and guiding the next generation and safeguarding its wellbeing, functions as an intergenerational conduit, bridging the developmental stages of older individuals with those younger. Yet, applications of generativity, as a means to bridge generational gaps within rapid social change, remain underexplored in the intergenerational field. Using Singapore as a case study, and through focus group discussions with 103 older persons, this paper examines how older Singaporeans express their generative concern and internalize their generative capacities across different social settings and rapid socioeconomic transformation.

Introduction: Although successful aging (SA) studies have examined objective indicators such as disease and disability, physical and cognitive function, and social and productive engagement, as well as subjective indicators such as self-rated health, function, and well-being, the interplay among these indicators is rarely studied. We studied SA profiles that captured this interplay and evaluated the association of these profiles with mortality in the oldest-old.

Methods: Respondents were 1,000 Chinese Singaporeans aged ≥85 years during interview visits from 2017 to 2018.

The measures against the coronavirus disease (COVID-19) pandemic, such as lockdown, pose a major challenge to those who manage work and caregiving demands. Drawing on social cognitive theory, which emphasizes the critical role of self-referent thought and human agency in overcoming obstacles and striving toward goals, the present longitudinal study (prepandemic, during lockdown, and postlockdown) investigated work-family balance self-efficacy (WFBSE) and work-family balance (WFB) among working informal caregivers of older adults (i.e.

Objective: Network typology studies have identified heterogeneous types of older adults' social networks. However, little is known about stability and change in social network types over time. We investigate transitions in social network types among older adults, aged 60 years and older, and factors associated with such transitions.

Background: The importance of social network in mortality among older adults has been acknowledged. However, existing studies typically overlook the interplay among social network indicators, and seldom consider the change in social network over time. We take a person-centered approach to identify transitions between social network profiles, and examine the linkage of such transitions with subsequent mortality risk.

Background: Cerebrospinal fluid t-tau (CSF t-tau) is a measure of neurodegeneration in Alzheimer's disease (AD) and has been increasingly demonstrated to be a non-specific biomarker within the AD continuum.

Objective: We sought to test whether t-tau influences the longitudinal effects of amyloid-β (Aβ) and phospho-tau (p-tau) on memory and executive function (EF) in mild cognitive impairment (MCI).

Methods: 319 MCI individuals from the Alzheimer's Disease Neuroimaging Initiative (ADNI) with baseline and 2-year CSF Aβ, p-tau, t-tau, and neuropsychological assessments were studied.

Prospective memory (PM) enables us to execute previously conceived intentions at a later time and is used when remembering to call a friend or submitting a proposal on time. Evidence that sleep benefits PM is presently mixed. Further, when a benefit is observed, it is unclear if this is achieved through improvements in strategic monitoring (maintaining an intention in mind and searching for cues) or spontaneous retrieval (an automatic process occurring without preparatory attention).

Wealth inequality is a prevalent social issue. The present study focuses on acceptance of wealth inequality, and considers personal income, perceived upward mobility, and future time perspective as its antecedents, and collective action intention as its outcome. With reference to the social identity literature and socioemotional selectivity theory, we posit a conditional indirect effect of income on collective action intention through acceptance of wealth inequality: only when mobility and future time perspective are relatively high, higher income is associated with higher acceptance of wealth inequality and in turn, lower collective action intention.

Study Objectives: To determine the effects of changes in nocturnal sleep and daytime nap durations on all-cause mortality among older adults.

Methods: Two-thousand four-hundred forty-eight community-dwelling older Singaporeans (≥60 years) reported their nocturnal sleep and daytime nap durations at baseline (2009) and the 2-year follow-up. At each phase, they were grouped into the recommended (7-8 hours), short (≤6 hours), and long (≥9 hours) sleep duration categories, and the none (0 hour), short (≤1 hour), and long (>1 hour) nap duration categories.

Scholars are divided as to whether sexting-an unprecedented sexual activity using digital media-is objectifying or sexually liberating. One notion is that sexting involves the representation of an individual's sexuality in the presence of others and thus reinforces objectification. Another perspective contends that the self-portrayal of the body in sexting facilitates the exploration of sexual subjectivity and is, therefore, sexually liberating.

To evaluate and extend climato-economic theory, the use of more micro units of analysis, such as cities and families, may open up new data sources. The consideration of environmental demands other than thermal climate may also broaden the range of useful data. Longitudinal designs can provide causal evidence, and so can experiments if the theory can be applied to individuals.
