Estimation of fertility and mortality of the Kuwaiti population.

Indirect techniques are applied to estimate the current level of fertility and mortality among Kuwaiti nationals in Kuwait during 1980-85. The various methods discussed provide estimates in the vicinity of 45 per thousand for birth rate and 8 per thousand for death rate. While child spacing by birth order in Kuwait is about 2 years, the proportion of childlessness is very low (1%). As a consequence of lower mortality and stable high fertility, the Kuwaiti population remains young.

Estimating infant mortality rates prospectively in Honduras.

In order to determine the validity of infant mortality estimates based on retrospective reporting, the Honduran Ministry of Health carried out a follow-up survey of women interviewed in a 1987 national survey. Women were interviewed approximately 14 months after the baseline survey and were asked about the outcomes of their pregnancies and the survival status of their young children. The overall infant mortality rate calculated from the follow-up survey was lower than that obtained from the baseline survey, due to the particularly low rate among the group of women who were pregnant at the time of the baseline survey. Possible explanations for this low rate are discussed.

Determinants of coitus after childbirth.

Using a sample of 3080 women from Cebu, Philippines, interviewed immediately after childbirth and every 2 months thereafter for 2 years, the determinants of return to coitus are analysed. Eighty per cent of the women returned to coitus before the return of menses, and 90% did so before stopping breast-feeding. In hazards models, variables associated with traditional life styles retarded return to coitus. Situational variables (husband resident, crowding, children aged 6 and under), especially husband residence, and biological variables (mother's age, return to menses, and lactation) were significant predictors of return to coitus. The implications of the analysis for the construction of models of birth interval dynamics are discussed.

Emerging patterns of child-spacing in Canada.

This study used data from the 1984 Family History Survey conducted by Statistics Canada to examine recent trends and patterns of child-spacing among currently married women. Life table and proportional hazards estimates show that Canadian women, particularly those in younger age groups with higher education and longer work experience, start having children late, but have subsequent children rather quickly. This suggests that such women tend to complete childbearing within a compressed time period.

Survival in the perinatal period: a prospective analysis.

A prospective study of 3080 Filipino mothers and non-twin births in 33 communities is used to study the determinants of mortality in week 1 postpartum. The results show significant nonlinear birth weight effects and the importance of environmental contamination, particularly for infants born by traditional methods at home, and several other intermediate and underlying determinants of perinatal mortality. The pathways through which important sociodemographic factors affect perinatal mortality are also presented.

Measuring excess risk of child mortality: an exploration of DHS I for Burundi, Uganda and Zimbabwe.

This paper proposes a new method of measuring excess risk of child mortality in cross-sectional surveys, which is applied to DHS I data for Burundi, Uganda and Zimbabwe. The expected child mortality experience is estimated for each mother on the basis of child's age, mother's age at child's birth and her parity, and compared with her observed experience. Mothers who exceed their expected child mortality experience and also had more than one child die are considered to have excess child mortality. Zimbabwe had the greatest concentration of child deaths as measured by a simple ratio of mothers to deaths, but when observed experience was compared with expected it had less than half as many excess deaths as Uganda and Burundi. In all three countries mother's education had a strong negative association with the risk of excess child mortality, and in Zimbabwe and Burundi there were significant regional differences.

The living arrangements of elderly people.

"In order to assess possible future trends in the living arrangements of elderly people and their implications, we need to understand the causes of...relatively recent changes. Analysts have variously stressed demographic trends, economic factors and behavioural or cultural shifts as major influences on changing household patterns. These arguments are reviewed [in this article]." Aspects considered include the availability of spouse and children, coresidence between elderly parents and children, cultural factors, income, and health and health care. The primary geographical focus is on the United Kingdom, with some additional information for the United States and selected other developed countries.

Life cycle economic and environmental implications of using nanocomposites in automobiles.

By reducing the energy and materials required to provide goods and services, nanotechnology has the potential to provide more appealing products while improving environmental performance and sustainability. Whether and how soon this potential could be realized depends on phrasing the right research and development (R&D) questions and pursuing commercialization intelligently. A sufficiently broad perspective at the outset is required to understand economic and technical feasibility, estimate life cycle environmental implications, and minimize unanticipated negative impacts. The rapid rise in federally funded nanotechnology R&D dictates that consideration of societal benefits will have a large role in setting the R&D agenda. We estimate potential selected economic and environmental impacts associated with the use of nanotechnology in the automotive industry. In particular, we project the material processing and fuel economy benefits associated with using a clay-polypropylene nanocomposite instead of steel or aluminum in light-duty vehicle body panels. Although the manufacturing cost is currently higher, a life cycle analysis shows potential benefits in reducing energy use and environment discharges by using a nanocomposite design.

Saving lives in the present versus saving lives in the future--is there a framing effect?

This study considers how to compare programs which are designed to save lives. "To estimate the discount rate for lives saved in the future a number of studies have been carried out on the trade-off between saving lives now and in the future. A telephone survey is administered to about 1,700 individuals [in Sweden] to test if the framing of the question affects the estimated trade-off. In one sample the question is framed as saving 100 lives today versus saving x future lives and in one sample the question is framed as saving 100 future lives versus saving y lives today. The result shows that the framing has a major impact on the trade-off."
