Cohort size and age-specific suicide rates: A contingent relationship

Trends in age-specific suicide rates relate to debates about the consequences of population aging and changes in cohort size for social well-being. Easterlin argues that large cohort size increases suicide rates by reducing relative income; Preston claims that suicide rates fall in large cohorts with high levels of political and social power. To integrate these competing arguments, this paper uses aggregate data on 18 high-income nations from 1953 to 1986 to demonstrate that the direction and strength of the relationship between cohort size and suicide depend on (1) age of the cohort, (2) gender, (3) national context, and (4) time period. The results show that large cohort size raises suicide for the young and middle-aged, but reduces it for the elderly. Also, the effects of cohort size prove stronger for men than for women, for nations with less collectivist institutions than for nations with more collectivist institutions, and for the 1950s and 1960s than for the 1970s and 1980s.     

On the relationship between population and education]

The social and historical development of population and education is subject to the restriction of the means of production. Although it is not the major factor in determing the direction of social development, it has a great impact on social progress and historical development. The scale and level of educational development are not only influenced by social and economic conditions but are also related to the scale of population growth and the number of people who receive an education. In studies of the relationship between the population and education, special attention should be given to the impact of population growth upon education as well as the everlasting influence of education upon the population structure and social mobility. Since 1949, because of a rapid population growth, the existing educational system in China has suffered severe damage and destruction. There have been an insufficient number of schools and a shortage of funds for education for quite some time, and the population growth has caused great pressure on education. The relationship between the population and education in a modern society is a rather complicated problem. As a country with a large population and a backward education, China needs to develop its education and promote its population quality in order that favorable conditions may be created for the overall development of Socialist modernization.     

Parental wealth and children's outcomes over the life-course in Brazil: A propensity score matching analysis

Parental wealth – as distinct from income, education and other parental socioeconomic resources – may play a large role in children's socioeconomic outcomes, particularly in developing countries, characterized by economic volatility, a weak social safety net and limited access to credit. Using a propensity score matching approach, we examine the influence of parental wealth on adult children's schooling, school quality, occupational status, consumption level, and wealth holdings in Brazil. Findings suggest a substantial effect of parental wealth on all these outcomes, with a positive effect of even modest levels of wealth. The effect of parental wealth on occupational status is largely mediated by parental investment in more and better education for children. In contrast, the effect on children's consumption and wealth is largely unmediated by labor market resources and rewards, a pattern that is more pronounced for sons than for daughters. This suggests direct parental financial assistance. Sensitivity analysis indicates that hidden bias emerging from unobserved confounders should have to be unlikely large to question inference of a causal influence of high levels of parental wealth, although the influence of low levels of wealth may be more susceptible to hidden bias.     

Selections and social selectivity on the academic track: A life-course analysis of educational attainment in Germany

Graduating from university is just the final step of an extended educational career. Sociological transition research has revealed that final educational attainment must be understood as the result of a sequence of successive decisions. With regard to graduation from university, one has to take into account that upper secondary school qualifications are required for enrolling in the first place, and in Germany, the decision for this kind of schooling is at a much earlier age. So where on the long way to the university degree does Germany ‘lose’ its potential academics and in particular its lower class children?     

Refining the association between education and health: The effects of quantity, credential, and selectivity

We refine the established association between education and health by distinguishing three aspects of a person's education (quantity, credential, and selectivity) and by examining the mechanisms through which they may correlate with health. Data are from the 1995 Aging, Status, and the Sense of Control Survey, a representative U.S. national telephone survey of 2,593 respondents aged 18 to 95, with an oversample of elderly. Results show that physical functioning and perceived health increase significantly with years of formal education and with college selectivity for those with a bachelor's or higher degree, adjusting for age, sex, race, marital status, and parental education. The credential of a college degree has no net association with physical functioning and perceived health beyond the amount attributable to the additional years of schooling. Of the three aspects of education, years of schooling has the largest effect. Most of that association appears attributable to its correlation with work and economic conditions, social psychological resources, and health lifestyle. A large portion of the net association of college selectivity with physical functioning and perceived health appears attributable to health lifestyle.     

Racial differences in birth health risk: A quantitative genetic approach

In the United States the gap between black and white babies' birth weights has remained largely unexplained. Rather than trying to measure all relevant variables, we used a genetically informative design to study the relative importance of genetic and environmental factors. Employing multiple indicators of "birth health risk," we found that the racial differences increased with the magnitude of the shared environmental effects. This suggested that possible genetic effects would not pertain to fetal genes, although genes affecting the mother's physical or physiological characteristics could be important because they contribute to shared environment in our analysis.     

A neo-classical education transitions approach: A corrected tale for three cohorts

Analysts have regarded education transitions research as revealing late stage educational egalitarianism in the United States (e.g., Stolzenberg, 1994) and as sufficiently robust to guide policymakers (e.g., Hout, 2007). However, critics suggest parameter estimates are contaminated by selection bias (e.g., De Graaf & Ganzeboom, 1993), key parameter differences are unidentified (e.g., Cameron & Heckman, 1998), cross-transition comparisons are faulty, and the data are inappropriate. Useful modifications have been offered, (e.g., [Breen and Jonsson, 2000], [Hauser and Andrew, 2006] and [Lucas, 2001]), but analysts have yet to comprehensively address the challenges critics pose. In response, we propose a neo-classical education transitions approach that uses fuller sets of data and models that explicitly address the primary threats to proper inference. Using this approach we re-assess the educational attainment process for a baby boomer cohort, a Generation X cohort, and a Generation Y cohort. All cohorts fail to replicate the waning coefficients pattern. Methodologically, the study responds to criticisms in a way that offers methods for continued cross-national comparative research. Substantively, the study undermines confidence that standard education transitions research can provide policy guidance and the claim of late stage egalitarianism in the United States educational attainment process.     

Best practices for online Canadian prenatal health promotion: A public health approach

Background

Prenatal health promotion provides information regarding pregnancy risks, protective behaviours and clinical and community resources. Typically, women obtain prenatal health information from health care providers, prenatal classes, peers/family, media and increasingly, Internet sites and mobile apps. Barriers to prenatal health promotion and related services include language, rural/remote location, citizenship and disability. Online public health platforms represent the capacity to reach underserved women and can be customised to address the needs of a heterogeneous population of pregnant women.

By all measures: an examination of the relationship between segregation and health risk from air pollution

A great deal of evidence suggests that African-Americans in more racially segregated communities are at a higher risk for a variety of health problems. Scholars have argued that these health inequalities might be explained by racial differences in exposure to air toxins. However, there are a number of ways to measure segregation, each representing different pathways of exposure. There has yet to be a systematic evaluation of how exposure to air toxins varies by these different measures, making it difficult to begin to theorize about the causal story linking segregation, pollution and health. This paper addresses this gap by examining how the health risk from industrial toxins varies by the 19 most commonly used segregation measures. Results show that, with the exception of two segregation measures, living in metro areas with relatively higher segregation levels, is associated with significantly greater health risk from industrial air toxins for all racial groups. Moreover, African-Americans in more segregated metro areas typically experience an added risk of exposure compared to non-Hispanic whites.     

Pregnancy-related dropouts and gender inequality in education: A life-table approach and application to Cameroon

In this study, I used a life-table approach to estimate how much hypothetical reductions in pregnancy-related dropouts would help close the gender gap in educational attainment. Using the schooling histories of 6,686 pupils, I partitioned Cameroon's gender gap in education into "pregnancy-related" and "non-pregnancy-related" components and simulated the impact of reductions in pregnancy-related dropouts on this gap. The results suggest that such reductions would have substantial payoffs in this setting, but payoffs would be the greatest where societies also address gender inequities before puberty and outside the realm of pregnancy. Reductions in pregnancy-related dropouts complement but do not replace efforts to reduce gender discrimination in schooling. Recent data from Demographic and Health Surveys should make it possible to extend this analysis to other countries.     

Residential patterns of parents and their married children in contemporary China: A life course approach

This paper examines the residential pattern of parents and their married children in contemporary China. Using the China Health and Nutrition Survey (1991, 1993, 1997), the analysis shows that the residential pattern of parents and their married children is not a static phenomenon, but changes over the life span. The analysis provides evidence that parental residence often responds to changed circumstances over the life course, adjusting to the need of married children as well as that of their parents. It is found that childcare needs, death of one parent, and health status of parents all play important roles in transitions in parental residence.     

The causal relationship between female labor supply and fertility in the USA: updated evidence via a time series multi-horizon approach

The purpose of this paper is to investigate the causality between female labor supply and fertility in the presence of auxiliary variables such as education, female wages, and male relative cohort size. We employ annual time series data spanning the period 1948 to 2007 for both an aggregate and an age-specific group. Our econometric specification follows closely the concepts and procedures proposed by Dufour and Renault (Econometrica 66(5):1099–1125, 1998) and Dufour et al. (J Econom 132:337–362, 2006) in that we conduct multi-horizon causality tests that allow for direct and indirect effects to take place. The sign and economic importance of our results is assessed via the estimation of impulse response functions. Our results establish bidirectional indirect causality between female labor supply and fertility and suggest interesting causal chains among the system variables. Causality effects are stronger for the age-specific group.     

The relationship between measures of subjective and economic well-being: A new look

The objective of this research is to examine the importance of variable specification in using economic variable to explain the variance in individual's perceived (1) overall psychological, (2) economic, and (3) non-economic well-being. Results indicate that careful specification of economic variables improves the explained variance of perceived subjective well-being. Specification of dependent variable, life satisfaction, based on a domain-specific scale, proves superior to using the response to the global satisfaction question, “How do you feel about life as a whole?’ Economic variables prove significant in explaining both perceived economic and non-economic domains of life satisfaction. Although its overall effect on life satisfaction is negative, increased family size is found to enhance non-economic life satisfaction, while detracting from economic aspects of life satisfaction.     

1982～2010年期间四次全国人口普查数据一致性研究——基于出生人口队列的分析

数据一致性是反映人口普查数据质量高低的重要指标。文章以第三、四、五、六次全国人口普查数据为基础,充分考虑人口死亡因素,比较同一出生队列人口在不同普查年份的人口规模,以此对人口普查数据一致性进行检验。研究中主要有三点发现:一是分时期进行分析,在"三普"至"六普"的28年间,九成以上出生队列人口存活率大于1,发生正偏离现象;二是对四次人口普查中的相邻两次普查依次进行比较,普查时处于0～90岁的91个出生队列人口偏离量逐渐增大,偏离率渐次上升;三是分性别来看,1982～2000年出生队列人口偏离程度存在显著性别差异。相当数量的出生队列人口出现系统性正偏离,表明在人口普查中存在较为严重的人口漏报、人口重报或死亡漏报。     

Ethnic variations in the relationship between income and fertility

The effects of husband'spotential andrelative incomes on completed fertility, as well as their effects on certain parity progression probabilities, are examined within samples of Anglos, Blacks and Mexican Americans. Relationships are estimated using data from the one-percent 1960 and 1970 U.S. Public Use Samples. The results reveal different patterns of relationship by ethnicity between the measures of income and the measures of fertility. The effects on completed fertility of the income measures are positive for Anglos and negative for Blacks, while in the case of Mexican Americans the effect ofpotential income is negative and that ofrelative income is positive. Income effects on the parity progression probabilities are similar in pattern to those from the analyses using completed fertility, although somewhat different patterns tend to appear at different birth orders, especially among Anglos.     

Exploring spatial patterns of carbon emissions in the USA: a geographically weighted regression approach

This paper uses US county-level data and the Stochastic Impacts by Regression on Population, Affluence, and Technology framework to explore the extent of geographical variability in the process that links total emissions of carbon dioxide to measures of population, affluence, and technology. Geographically weighted regression models show that there is strong evidence of spatial heterogeneity in the estimated elasticities of emissions. While this research cannot explain these regional patterns, it may provide a useful starting point to examine in detail the nature of regional variation.     

A note on the changing relationship between fertility and female employment rates in developed countries

In this paper we look at a panel of OECD aggregate fertility and labor market data between 1970 and 1995 and we report some striking recent developments. Total Fertility Rates (TFR) were falling and Female Participation Rates (FPR) were increasing, conforming to a well known long-run trend. Along the cross-sectional dimension, the correlation between TFR and FPR was negative and significant during the 1970's and up to the early 1980's. This seemed consistent with secular comovements. However, by the late 1980's the correlation had become positive and equally significant. We discuss our findings within the framework of standard neoclassical models of fertility and labor supply adapted to macro data, as in Butz and Ward (1979).

The relationship between homosexuality, internalized homo-negativity, and mental health in men who have sex with men

Whether homosexuality or internalized homo-negativity is the critical variable affecting the mental health of men who have sex with men has long been debated. As part of a larger study, 422 Midwestern homosexual men completed questionnaires examining degree of homosexuality, internalized homo-negativity, and depression. Logistic regression modeling identified internalized homo-negativity, but not degree of homosexuality, as significantly associated with greater adjustment depression (OR = 1.5), major depression (OR = 2.6), dysthymia (OR = 1.5), and likelihood of being in therapy (OR = 1.4). Internalized homo-negativity was also negatively associated with overall sexual health, psychosexual maturation, comfort with sexual orientation, "outness," and peer socialization. Internalized homo-negativity, not homosexuality, appears associated with negative health outcomes. Providers should promote sexual health and avoid interventions that reinforce internalized homo-negativity.
