Although the nearly one in seven Americans who have disabilities share many characteristics, the attitudes toward and the programs, care models, expenditures, and goals for people with disabilities differ substantially across age groups in ways that suggest ageism. Expenditures per recipient are substantially higher for younger individuals with disabilities, largely as a result of more effectiv...

Many studies specify human mortality patterns parametrically, with a parameter change affecting mortality rates at different ages simultaneously. Motivated by the stylized fact that a mortality decline affects primarily younger people in the early phase of mortality transition but mainly older people in the later phase, we study how a mortality change at an arbitrary age affects optimal retirem...

abstract background: leukemia is the most common malignancy in childhood, and acute myeloid leukemia (aml) is the second most common leukemia.aml still accounts for more than 30% of deaths from leukemia. aml is classified into several subgroups from m0 to m7 with different presentations, clinical features, and outcomes. material and methods: between march 1996 and october 2003, 47 children with...

PURPOSE OF THE STUDY We examined the relationships among development of generativity, generative acts, and psychological well-being in old age and the possible mediating effects of perceived rejection and respect from younger generations. We hypothesized that generative action would not lead to well-being unless responding elders perceived respect from younger generations, and, further, that pe...

Elderly people show memory deficits over short retention intervals. One explanation for this effect that has been proposed is that the elderly have problems with inhibiting irrelevant material. To test this proposition, younger and older adults were compared on a short-term cued recall task in which proactive interference was manipulated. Elderly people were expected to be more susceptible to P...

BACKGROUND Understanding information about medical screening tests often requires estimating positive predictive values (i.e., posterior probabilities), which is a notoriously difficult task. Previous studies have shown that representation of information in terms of natural frequencies (i.e., counts of occurrences that preserve base rates) facilitates judgments of positive predictive values. Th...
