The variable-r model provides demographers with a way to explore the contributions of demographic components (fertility, mortality, migration) changes in populations’ age structures. However, traditional methods require extremely long mortali

The presentation is far from purely morphological in that many physiologic findings (natural and experimental) are cited. Radio-active iodine obviously has contributed heavily to this type of material, although there is not much said about the biochemistry of iodine-containing compounds. In general, this work will be of great interest to biologists and workers in the preclinical sciences. As to...

Old age psychiatry services globally are under threat. The discipline enjoyed its heyday in the two decades bridging the millennium. More recently there has been a move to integrate old age services with those of working age adults, to create 'ageless' services. Evidence is beginning to accumulate that this is a bad idea.

Starting in 2009, the Labor Insurance (LI) program in Taiwan has allowed workers to choose between pension old-age benefits and one-time old-age benefits. The introduction of the pension option not only mitigates longevity risk for workers but also provides a higher expected present value of old-age benefits to workers than the one-time benefit option (on average). Based on a lifecycle model wi...

This study examined the maintenance of retest learning benefits in young old and oldest old adults over an 8-month period in 3 cognitive abilities: reasoning, perceptual-motor speed, and visual attention. Twenty-four young old (aged 70-79 years, M = 74.2) and 23 oldest old adults (aged 80-90 years, M = 83.6) who participated in a previously published study (Yang, L., Krampe, R. T., & Baltes, P....

This paper examines income inequality over stages of the later-life course (age 45 and older) and systems that can be used to mitigate this inequality. Two hypotheses are tested: • Levels of income inequality decline during old age because public benefits are more equally distributed than work income; • Because of the progressive nature of government benefits, countries with stronger public inc...
