Ability, disability, and the oldest old

A measure of range of ability is used to profile the 85-years-old-and-older (oldest old) population, including the highly disabled institutional population. This new measure uses two new questions available in the 1990 Decennial Census concerning a self-care limitation and a mobility limitation as well as the usual question concerning a work limitation. In addition to examining the extent of disability among the oldest old, the article examines the extent of care potentially available in the household as well as the economic characteristics of this age group. It is also profiled in terms of relevant personal characteristics, including age, gender, marital status, race, ethnicity, rural residence, education, and employment. A key question addressed is the need for help or care among the oldest old and how various long-term care proposals would meet such needs. A careful analysis of this unique and growing population is necessary to both allay fears of the cost of care or help as well as to dispel stereotypes of this age group as frail and dependent, and in need of institutional care.     

Net worth and the economic diversity of the elderly

Using data from the 1984 panel of the Survey of Income and Program Participation (SIPP), this article examines characteristics of the older population disaggregated by net-worth quintiles. The authors argue that income is not a sufficient measure of economic status for current policy discussions on issues such as changing Medicare co-payments, increasing the taxation of social security benefits, or means-testing under Medicaid. Net worth is a better measure of economic status, particularly for the elderly, because it represents the net value of assets accumulated over the life course. Their results indicate that there is considerable diversity in the economic status of the older population, which is masked by aggregate statistics (such as means and medians) typically used to summarize the economic status of population groups. Stereotypical views of the elderly based on such aggregates result in misdirected policy formulation. In the future, policymakers will need to formulate policies and programs using information on the distributions of income and assets among the older populations rather than relying on statistical aggregates.     

Three dimensional stacking of containers

This paper reports the results of a simulation study into the stacking and handling of containers with the same dimensions. The measures of performance include volumetric utilisation, wasteful handling ratios, shortage ratio, and rejection ratio. The decision variables include the maximum dimensions of the store, stacking policies, and the different number of types of containers and their relative frequencies. The results indicate that the number of different types of containers has the largest impact on the measures of performance. The effects of the stacking policy and maximum store dimensions are also significant.     

A POPULATION PROFILE OF VERY OLD MEN AND WOMEN IN THE UNITED STATES

This article presents the first population profile of men and women age 85 and over. It was developed with the 1980 census PUMS sample A, of which nearly 70% were women. Men were better off than women in both socioeconomic and relational characteristics in that they had higher personal incomes from nearly all sources and were far more likely to be married and living independently. They were not found in nursing homes in as great a proportion as were very old women. In a sense, then, the generalizations about the very old have a female bias.     

Beyond the body: an emerging medical paradigm

As with so many other aspects of American society, the baby boom may be the catalytic factor that ultimately changes the way we treat our health.     

A strategic model of communications demand

Strategic planning of telecommunications supply takes place in an increasingly turbulent environment due to factors such as the development of new and improved telecommunications services, the convergence of computing and telecommunications technologies and the emergence of the information society. This article is concerned with a model of future communications demand, developed under a research contract placed by British Telecom. The model describes dynamic trends in the supply and demand for communications products and services over a 30 year time horizon. Some key model features are outlined and an overview of the computer programme is given. The aim of the project was to provide decision-makers with a flexible, analytical tool for the exploration of policy issues and environmental impacts. The model should not be viewed as a forecasting tool but as an aid to structured thinking and the rapid assessment of alternative scenarios.     

State and regional policy implications of elderly migration

This paper uses the 1980 Census data to estimate the size of the economic transfers associated with the 1985 to 1990 interregional migration of older persons. Total economic transfers are estimated by multiplying interregional migration flows of older persons by the average income of older persons in each migration stream. Assuming an average life expectancy of 15 years for elderly migrants and an expenditure multiplier of 2, the total redistribution of income as a result of 1985 to 1990 elderly migration is estimated to be over $600 billion. The South Atlantic and Mountain regions are the recipients of the largest positive net transfers; the East North Central and West North Central regions have the largest negative net transfers.     

Managing aging men in Asia: a strategic approach

We have established a comprehensive diagnostic paradigm for the management of aging men which seeks to evaluate the various determinants of the aging process in five major health areas: cardio-health, bone health, sex health, general health and endocrine state. This paradigm appears to be useful for the management of the problem of aging in our local population. It could be used for the management of individuals as well as for population research. When combined with the establishment of evidence-based management modalities, it will provide a useful tool for the holistic management of aging in Asia.     

Sex hormones and human behavior: a critique of the linear model

Behaviors in which human males and females differ are frequently attributed to fetal gonadal hormone exposures. Much current thinking on this topic relies on a model of explanation the authors call linear-analytic. This model emerges from studies of hormone-behavior relationships in nonhuman animals. Examining three areas of hormone-behavior research in humans, the authors argue that the form of explanation is inappropriate to the behavioral phenomena being explained. They urge the adoption of a more complex neurobiological approach that emphasizes the role of the cerebral cortex and correlatively minimizes the role of fetal hormones.
