Self-perception of aging and health among older adults in Korea

The way that each individual perceives his or her own aging and health may be a key indicator of adaptation and well-being in old age. This study explored the determinants of self-perception of aging and health using 291 community-dwelling older adults in Korea (mean AGE=69.9). Older individuals with lower levels of education and economic status and various types of health problems (more chronic conditions, greater disability, poorer vision, and greater numbers of sick days) were found to have more negative self-perception of aging and health. In addition, a significant role of psychological factors was observed. For self-perception of health, sense of mastery was found to be a significant factor, and for self-perception of aging, neuroticism was observed to be significant along with sense of mastery. The mediating role of self-perception of health was supported that positive perception of health intervened the adverse effects of health problems on self-perception of aging. The findings demonstrate the important roles of psychological resources and subjective perceptions and suggest a need to consider them when planning interventions.     

Characterizations of the poisson process using,the variance

Let γ(t) be the residual life at time t of the renewal process {A(t), t > 0}, which has F as the common distribution function of the inter-arrival times. In this article we prove that if Var(γ(t)) is constant, then F will be exponentially or geometrically distributed under the assumption F is continuous or discrete respectively. An application and a related example also are given.     

Tests for random time effects and spatial error correlation in panel regression models

We consider a panel model with spatial autocorrelation and heterogeneity across time. Various Lagrange multiplier and likelihood ratio test statistics are developed for testing time effects and spatial effects, jointly, marginally or conditionally. Limiting null distributions of the tests are derived. Size and power performances of the proposed tests are compared by a Monte-Carlo experiment.

Assessment in Adult Protective Services: do multidisciplinary teams make a difference?

This study compared 2 approaches to the assessment of Adult Protective Services (APS) cases. Using administrative data from 869 cases in 2 counties in Maryland, the differences between a nurse/social worker team and a lone social worker in case disposition, risk reduction, recidivism, and cost effectiveness were examined. Lone social workers were significantly more likely to confirm financial exploitation, physical abuse, and neglect by others; while the team approach resulted in significantly greater risk reduction. No differences were observed in relation to recidivism, self-neglect and cost savings. Given limited resources, research that examines optimal staffing patterns in APS agencies is warranted.     

Postretirement work and volunteering by poverty groups informed by role theory

This study uses role theory to examine the association between postretirement work and volunteering among retirees and to determine whether this association varies across poverty status. Data came from the 2012 wave of the Health and Retirement Study (HRS). The sample was restricted to respondents of older retirees (N = 6,619). We found that postretirement work positively influenced volunteering. However, poverty can be a risk factor of volunteering among older retirees. The positive effect of post-retirement work was found to be more significant in the near-poverty group. We provide an empirical foundation to help inform volunteer programs for retirees.
