Recycling in multi-family dwellings: Increasing participation and decreasing contamination

This study explored the promotion of recycling in multi-family dwellings. An experimental design investigated four behavior change techniques: biweekly postcards giving specific feedback to each dwelling unit as to quantity and contamination of the recyclables, newsletters giving general information on recycling and the amount recycled by the city as a whole, written pledges committing households to recycle for a specified period, and volunteer coordinators who distributed information and answered questions from residents. The effectiveness of these techniques was compared against that of a control group. The findings suggest that volunteer coordinators are not an effective intervention technique in multi-family dwellings, and that feedback and commitment techniques are useful mainly for managing contamination in medium sized complexes. The data also suggest that the size of a multi-family dwelling complex significantly affects the amount of recyclables collected and the level of contamination. Smaller complexes with less than ten units recycled up to three times the amount on a per unit basis as complexes with more units. Smaller units also had fewer problems with contamination in their recyclables. Several explanations are offered for the poor participation and performance in larger complexes.     

Disability in Herefordshire, 1851-1911

Disability history is a comparatively new field of study, and to date little use has been made of the British census as a source because of its perceived difficulties. This article shows that it is possible to study a local, disabled population in the second half of the nineteenth century from this source, even thought the way in which individuals' disabilities are described can sometimes vary from one census to the next. Age distribution for each condition and was found to vary between those with congenital and those with acquired conditions. Among those with a handicap of sight, hearing or speech a higher proportion remained unmarried. Disabled people were likely to remain in the parental home until their late thirties, and when their parents died they moved in with siblings or became a lodger or inmate. Although few of the disabled children seemed to be receiving education, over 60 per cent of the adult males were found to be working and almost 25 per cent of the adult females. Disabled people, it appears, were viewed not merely as statistics, but were included as members of the local population, and not always dependent members.     

Migration distances: An international comparison

Comparing the level or amount of migration within different countries has been a longstanding problem because the local administrative areas commonly used as the basis for measuring migration vary greatly in size and significance within and between countries. Distance moved is a critical aspect of most concepts of migration, and measuring it would facilitate cross-national comparisons. Apparently only the United States, Great Britain, and Sweden have measured migration distances for the country as a whole, and this information is used as the basis for comparative analysis of spatial mobility.     

Trends in intercountry adoption: Analysis of data from 20 receiving countries, 1998–2004

The implications of developments in intercountry adoption worldwide in the early years of the twenty-first century are explored, based on analysis of data from 20 receiving countries. Between 1998 and 2004, intercountry adoption increased by 42 per cent. Problems in data collection and analysis are examined, as is the reliability of estimates of numbers of children sent by countries of origin when derived from data provided by receiving countries. Also considered are various measures of standardization which can be used to facilitate comparison between countries and show trends over time. The potential for more detailed comparative analysis is explored.     

Business visits,knowledge diffusion and productivity

We investigate whether labor mobility can be a distinct source of growth by studying the productivity impact of business visits (BVs), vis-à-vis that of other well-known drivers of productivity enhancement. Our analysis uses an unbalanced panel—covering on average 16 sectors per year in ten countries during the period 1998–2011—which combines unique and novel data on BVs sourced from the US National Business Travel Association with Organization for Economic Cooperation and Development (OECD) data on R&D and capital formation. We find that mobility through BVs is an effective mechanism to improve productivity, being about half that obtained by investing in R&D. This relevant finding invites viewing short-term mobility as a strategic mechanism and prospective policy tool to overcome productivity slowdowns and foster economic growth.     

Older adults in sub-Saharan Africa living with children and grandchildren

Using data from Demographic and Health Surveys, we examine the composition of households containing older adults in 24 countries of sub-Saharan Africa, with a focus on those living with children and grandchildren. Overall, 59 per cent live with a child and 46 per cent with a grandchild. Men are more likely to live in nuclear households and women in extended households and alone. Regression analyses show that individual-level determinants of household composition differ by sex. For example, living with children and grandchildren is tied to living with a spouse for men, but for women the effect is either not significant or in the opposite direction. Households with an older adult and a grandchild, but no adult children, are common. Usually the adult child lives elsewhere, though about 8 per cent of older adults live with a grandchild who has at least one deceased parent. Older adults are more likely to be living with double-orphans in countries with high AIDS-related mortality.     

Fertility,social mobility and urban migration in Brazil

In the course of a sample survey of the adult population of eight cities in southcentral Brazil conducted in 1959 and early 1960, material was obtained respecting total family size after ten or more years of marriage. This was analysed in order to determine what variations in mean family size could be observed in relation to class status and social mobility. The results generally corroborate those of J. Berent for England and Wales–that is, that fertility is inversely related to class status, and that for a given class, the lower the class of origin, the higher the fertility. There was no confirmation, however, of J. Goldberg's findings in Detroit that the inverse relationship between class and fertility is due to the presence in urban populations of the rural-born, and suggestions are put forward which may explain this result in Brazil. A tentative estimate suggests that the net effect of social mobility had been to reduce the sample's total births by something of the order of 3 per cent.     

Family planning in choiseul province,Solomon Islands

The results presented are from a rural prevalence survey on family planning in Choiseul Province, Solomon Islands. Married women aged 15–49 years with at least one living child and married men whose wife met the same criteria, provided data on knowledge, attitudes and practices of contraceptive use. Fifty one per cent of the female sample were using some form of contraception, 26 per cent reversible and 25 per cent non-reversible methods. Sixty-five per cent of men claimed that they or their spouse were using a method of family planning. Tubal ligation was the most common currently used method (25 per cent in the female survey). Desired family size was four for both males and females. Knowledge and approval of family planning was high, with 83 per cent of females and 81 per cent of males knowing of at least one method. Problems in accessing information and services for family planning include cultural and logistical constraints. Religious affiliation was the major variable affecting knowledge, use and approval of contraceptive methods. Nearly a quarter of the sample lived further than two hours travel time from the nearest health clinic supplying contraceptive methods. These clinics often have only an intermittent availability of supplies. A strong interest in family planning was demonstrated by both respondents and service providers.     

Neo-natal mortality in South Asia: The special role of tetanus

First-year mortality in rural Uttar Pradesh is characterized by a predominance (60 per cent) of deaths during the first month of life, of which 66 per cent are reported to be due to tetanus. This pattern is not typical of the historical experience of many developed countries and the current experience of some less developed countries where post-neo-natal mortality predominates. To examine this phenomenon, two causal models of neo-natal mortality (one for tetanus and one for all other diseases) are developed and tested using retrospective survey data from 2000 couples living in rural Uttar Pradesh.

Neo-natal tetanus mortality is found to be primarily a function of opportunities for exposure to the disease (e.g. lack of antiseptic birth practices, ownership of large animals) rather than of socio-economic status or demographic variables. The importance of examining neo-natal mortality by cause, and the shortcomings inherent in making inferences from the historical experiences of Western nations are emphasized.

Selective migration and health in the USA, 1984-93

Using data from the Panel Study of Income Dynamics, we investigated the impact of health on domestic migration within the USA. We find that, for men below 60 years of age, a move from the middle to the bottom of the health distribution reduces mobility by 32-40 per cent. Non-random attrition from the panel implies that these are lower bounds. By contrast, we find evidence that, among older men, there is higher mobility at the top and bottom of the health distribution than there is in the middle. For women, we find no evidence of a relationship between their own health and mobility, although spouse's health does affect the mobility of married women.     

The end of population growth in Asia

This paper presents probabilistic population projections for five regions of Asia (South Asia, Central Asia, China region, Pacific OECD and Pacific Asia) and Asia as a whole. Over this century, Asia will experience very heterogeneous demographic development: Central Asia is expected to almost double in population and South Asia will become by far the world’s most populous region, rapidly surpassing the China region. Simultaneously, the Pacific OECD countries are likely to shrink in population size and experience extreme population ageing. The proportion of the population aged 60 and above in these countries (with Japan having the greatest weight) is expected to reach 50 per cent of the total population (with the 95 per cent uncertainty interval ranging from 35 to 61 per cent). The China region will experience a more rapid speed of ageing, with the proportion aged 60 and above expected to increase by a factor of four from 10 per cent in 2000 to 39 per cent in 2100.     

Children’s educational attainment,occupation, and income and their parents’ mortality

Using data from Finland, this paper contributes to a small but growing body of research regarding adult children's education, occupation, and income and their parents' mortality at ages 50+ in 1970–2007. Higher levels of children's education are associated with 30–36 per cent lower parental mortality at ages 50–75, controlling for parents' education, occupation, and income. This association is fully mediated by children's occupation and income, except for cancer mortality. Having at least one child educated in healthcare is associated with 11–16 per cent lower all-cause mortality at ages 50–75, an association that is largely driven by mortality from cardiovascular diseases. Children's higher white-collar occupation and higher income is associated with 39–46 per cent lower mortality in the fully adjusted models. At ages 75+, these associations are much smaller overall and children's schooling remains more strongly associated with mortality than children's occupation or income.     

The boundaries of genocide: Quantifying the uncertainty of the death toll during the Pol Pot regime in Cambodia (1975–79)

The range of estimates of excess deaths under Pol Pot's rule of Cambodia (1975–79) is too wide to be useful: they range from under 1 to over 3 million, with the more plausible estimates still varying from 1 to 2 million. By stochastically reconstructing population dynamics in Cambodia from extant historical and demographic data, we produced interpretable distributions of the death toll and other demographic indicators. The resulting 95?per cent simulation interval (1.2–2.8 million excess deaths) demonstrates substantial uncertainty over the exact scale of mortality, yet it still excludes nearly half of the previous death-toll estimates. The 1.5–2.25 million interval contains 69 per cent of the simulations for the actual number of excess deaths, more than the wider (1–2 million) range of previous plausible estimates. The median value of 1.9 million excess deaths represents 21?per cent of the population at risk.

A New Proposal to Gauge Intergenerational Mobility: Educational Mobility in Europe as a Case Study

This paper is aimed at presenting a new intergenerational mobility index that (a) combines the intergenerational elasticity and the R-squared of the intergenerational regression and (b) enables the expression of the total degree of mobility as the weighted sum of mobility with respect to both parents. As a case study, we apply our proposal to investigate the intergenerational mobility of education in several European countries and its changes across birth cohorts. The results derived from the proposed index indicate that Nordic countries display higher levels of educational mobility than Southern countries, whereas continental countries are in an intermediate position. Moreover, it appears that the degree of mobility increases over time only in those countries with low initial levels and remains stable for the most mobile countries. Finally, for most of the countries the proposed methodology can prove that the degree of educational mobility with respect to each parent tends to converge to the same level over the course of time.     

Demographic Research in Britain 1936–1986

We use data from the nationally representative 1997 Demographic and Reproductive Health Survey to examine use of maternity services in rural China. The data indicate that roughly 60 per cent of women had at least one prenatal visit, while 40 per cent had a professionally assisted birth over the period 1988–97. Despite China's shift from a more socialist to a more privatized health care system, use of maternity services increased over this period. These increases are consistent with the push toward integration of reproductive health into family planning that emerged after the 1994 International Conference on Population and Development and the 1995 Fourth World Women's Conference held in Beijing. At the same time, we find indirect evidence that the target-based population policy may well have exerted downward pressure on use of maternity services; differences by parity are marked and multilevel models predicting use of maternity services indicate underdispersion at the individual level.     

Reply to Wachter

Although twins constitute only about 2.4 per cent of total births in less developed countries, they account for about 12 per cent of neonatal deaths and about nine per cent of infant deaths. Twin mortality in less developed countries has almost never been analysed systematically. We examine survival among twins as contrasted with that among singleton births by using 2692 twin observations pooled from 26 standardized Demographic and Health Surveys. Weakened by gestational and other biological complications, twins seem to be more vulnerable to detrimental demographic and household socio-economic influences than singletons. Twinning tends to amplify, or at least retain, whatever group differences exist among singleton births.     

Economic opportunities,marriage squeezes and the propensity to marry: An economic analysis of period marriage rates in England and Wales

An economic model of the decision to marry has been developed by Gary Becker and is now part of the ‘new home economics’. From it one can deduce that the propensity to marry is a function of the relative earning capacities of men and women, the relative scarcity of unmarried persons of the opposite sex and real income. The effects of changes in these variables on the annual first marriage rates of men aged 16–19, 20–24 and 25–29 and women aged 16–19 and 20–24 respectively are estimated over the post-war period. It is found that women's earning capacity relative to men's has a particularly strong negative effect on marriage rates, and that the decline in first marriage rates during the 1970s was primarily attributable to the growing economic opportunities for women. As demographic studies have suggested, the relative numbers of bachelors and spinsters of particular ages (‘marriage squeezes’) also have a significant impact, and there is evidence of substitution in the ages of marriage partners in response to such ‘squeezes’. The income elasticity of marriage is only found to be significant among men below age 25 and women below age 20, and it increases as we move down the age distribution. This suggests the ‘liquidity constraints’ influence the timing of marriage among young people. In sum, this economic model is able to account for over 90 per cent of the post-war variation in young persons' marriage rates.
