A National Portrait of Stepfamilies in Later Life.

Scholars have documented increases in the prevalence and complexity of stepfamilies earlier in the life course, but no one has systematically investigated U.S. stepfamily structure in later life. Guided by a family systems approach, we described the prevalence and composition of later-life stepfamilies.

"It was the best worst day of my life": Narrative Content, Structure, and Process in Wisdom-Fostering Life Event Memories.

The purpose of this study was to examine laypeople's subjective understanding of their own wisdom development. To do this, autobiographical memories of wisdom-fostering life events were examined for (a) life-event characteristics, and (b) self-reflective processes believed to support growth in wisdom through life experience.

Purpose in Life Among Centenarian Offspring.

Purpose in life (PIL), a feeling of meaning and direction in life, is associated with favorable health outcomes including lower mortality and reduced risk of disease, disability, and cognitive impairment. Since centenarian offspring have been shown to have long health spans we sought to examine whether they have higher PIL than individuals without familial longevity.

The Role of Occupation in Explaining Cognitive Functioning in Later Life: Education and Occupational Complexity in a U.S. National Sample of Black and White Men and Women.

Positive associations between education and late-life cognition have been widely reported. This study examines whether occupational complexity mediates the relationship between education and late-life cognition, and whether the magnitude of mediation differs by race, gender, or education level.

A Commentary on Research on Death and End of Life Issues.

Volunteering Among Older Adults: Life Course Correlates and Consequences.

The Temporal Association between Executive Function and Life-Space Mobility in Old Age.

Life-space mobility, an indicator of community mobility, describes person's movements in terms of the distance from home, the frequency of movement and the need of assistance for movement. Executive function (EF) is a higher order cognitive function that supervises motor control, and plays a key role in a person's ability to function independently. Cognitive impairment often co-occurs with restricted life-space mobility, however, the direction of the longitudinal associations between EF and life-space mobil...

Awareness of Mild Cognitive Impairment and Mild Alzheimer's Disease Dementia Diagnoses Associated With Lower Self-Ratings of Quality of Life in Older Adults.

This study examined how awareness of diagnostic label impacted self-reported quality of life (QOL) in persons with varying degrees of cognitive impairment.

Biological Age, Not Chronological Age, is Associated with Late Life Depression.

The pathophysiology of late life depression (LLD) is complex and heterogeneous, with age-related processes implicated in its pathogenesis. This study examined the cross-sectional and longitudinal association between depressive symptoms and a baseline multibiomarker algorithm of biological age (BA) that aggregates indicators of inflammatory, metabolic, cardiovascular, lung, liver, and kidney functioning.

Midlife Systemic Inflammation is Associated with Frailty in Later Life: The ARIC Study.

Evidence suggests systemic inflammation may have a mechanistic role in age-related frailty, yet prospective data is limited. We examined whether systemic inflammation during midlife was associated with late-life frailty within the community-based Atherosclerosis Risk in Communities Study.

Academic career intentions in the life sciences: Can research self-efficacy beliefs explain low numbers of aspiring physician and female scientists?

A lack of physician scientists as well as a high female dropout rate from academic medicine and basic life sciences is a concern in many countries. The current study analyzes academic career intentions within a sample of recent doctoral graduates from medicine and basic life sciences (N = 1109), focusing on research self-efficacy beliefs as explanatory variable of gender and disciplinary differences. To ensure that differences in research self-efficacy could not be attributed solely to objective scientific ...

Effects of Mobility and Cognition on Maintenance of Independence and Survival Among Women in Late Life.

We examined the effects of mobility and cognition on maintenance of independence among women in late life.

Situation-Based Contingencies Underlying Wisdom-Content Manifestations: Examining Intellectual Humility in Daily Life.

Existing assessments of intellectual humility (IH)-a key component of wisdom-do not examine its manifestation in daily life while sufficiently focusing on the core idea of the construct: owning up to one's intellectual shortcomings. The present research sought to examine situational contingencies underlying daily manifestations of IH-relevant characteristics.

Sleep Duration and Sleep Disturbances as Predictors of Healthy and Chronic Disease-Free Life Expectancy between Ages 50 and 75: A Pooled Analysis of Three Cohorts.

The aim of this study was to examine the associations of sleep duration and sleep disturbances with healthy and chronic disease-free life expectancy (LE) between ages 50 and 75.

For Better or Worse? Couples' Time Together in Encore Adulthood.

This study examined the amount of time married couples share together in a new "encore adult" life course stage around the 50s, 60s, and 70s. Also investigated was the relationship between shared time and experienced well-being for this age group.

The Association between Trajectories of Physical Activity and All-cause and Cause-specific Mortality.

The benefits of physical activity (PA) for health have primarily been evaluated during midlife. Whether patterns of change in late-life PA associate with overall and cause-specific mortality remains unclear.

Early and Midlife Predictors of Wisdom and Subjective Well-Being in Old Age.

We explored whether wisdom and well-being in old age are the result of early personality traits related to personality growth or personality adjustment, respectively, or successful human development as outlined by Erikson's stage theory and the life course paradigm.

Adiposity, telomere length and telomere attrition in midlife: the 1946 British Birth Cohort.

Obesity has been linked with shorter telomere length, both of which have been implicated in ageing, but the impact of early life adiposity on telomere length is unclear.

Factors to consider in the verification of urinary biomarkers.

Reminiscence in Everyday Conversations: A Naturalistic Observation Study of Older Adults.

We examined older adults' social reminiscence behavior in everyday life, and the relation between reminiscence functions and well-being.

Long-term impact of childhood disadvantage on late-life functional decline among older Japanese: Results from the JAGES prospective cohort study.

Increasing evidence suggests an impact of childhood disadvantage on late-life functional impairment in Western countries. However, the processes by which childhood disadvantage affects functional capacity are influenced by several factors unique to particular societies. We examined the impact of childhood disadvantage on functional decline among older Japanese, using a large-scale prospective cohort study.

EPR in the USSR: the thorny path from birth to biological and chemical applications.

In 1944, electron paramagnetic resonance (EPR) was discovered by Evgenii Konstantinovich Zavoisky in the USSR (Union of the Soviet Socialist Republics). Since then, magnetic resonance methods have contributed invaluably to our knowledge in many areas of Life Sciences and Chemistry, and particularly in the area of photosynthesis research. However, the road of the magnetic resonance methods, as well as its acceptance in Life Sciences and Chemistry, was not smooth and prompt in the (former) USSR. We discuss th...

The Development of Wisdom: A Social Ecological Approach.
