There is no generally accepted procedure for identifying ultradian pulsations in hormonal time series. We suggest an approach based on removing long-term trends, such as diurnal rhythms, from the series of observations; identifying peaks in the residual series; and resolving each peak, if appropriate, into overlapping secretory episodes. The first step usesâ€¦ (More)

We apply aggregate demographic analysis and computer microsimulation to project the number of older Thais who will lose children to AIDS during their own lifetimes and to assess their involvement with ill children through caregiving and coresidence. Parental bereavements from AIDS are predicted to peak at around 80,000 per year between 2003 and 2007.â€¦ (More)

The history of preindustrial Europe provides an opportunity to examine the causes and consequences of population change at a macro level. However, serious statistical problems arise from the endogeneity of all observed variables in a Malthusian system (fertility, mortality, population size, and real wages), and from unobserved influences such as shifts inâ€¦ (More)

Computer microsimulation is capable of generating detailed reconstructions and forecasts of the numbers of living kin that members of a population have. The available detail, specificity, and consistency of vital rates for the past and the accuracy of vital rates projected for the future necessarily limit the accuracy of the kinship estimates that can beâ€¦ (More)

Bongaarts and Feeney offer alternatives to period life expectancy with a set of demographic measures equivalent to each other under a Proportionality Assumption. Under this assumption, we show that the measures are given by exponentially weighted moving averages of earlier values of period life expectancy. They are indices of mortality conditions in theâ€¦ (More)

Plateaus in the age pattern of hazard functions at extreme ages have been discovered in large populations of medflies, Drosophila, nematodes, and people. Mueller and Rose [(1996) Proc. Natl. Acad. Sci. USA 93, 15249-15253] have proposed several age-structured demographic models to represent effects of mutation accumulation and antagonistic pleiotropy onâ€¦ (More)

As population ageing strains social insurance systems, cohorts whose own fertility was low will be reaching elderly status, leaving close biological kin in short supply. However, there is a countervailing trend, inasmuch as burgeoning divorce, remarriage and family blending have expanded the numbers and varieties of step-kin and other non-standard kinshipâ€¦ (More)

Demographic computer microsimulation is applied to produce projections of numbers and distributions of close kin for the U.S. elderly of 2030. This paper reports results for the non-black population, with special emphasis on the numbers and possible roles of step-kin. The projections indicate that the elderly of 2030 are likely to be moderately deprived inâ€¦ (More)

W. D. Hamiltonâ€™s celebrated formula for the age-specific force of natural selection furnishes predictions for senescent mortality due to mutation accumulation, at the price of reliance on a linear approximation. Applying to Hamiltonâ€™s setting the full non-linear demographic model for mutation accumulation of Evans et al. (2007), we find surprisingâ€¦ (More)
