Effect of Conflict on Age at Marriage and Age at First Birth in Rwanda

Using Rwanda Demographic and Health Survey 2005 data, we estimate a Cox proportional hazard model to identify the determinants of age at marriage and age at first birth and whether these decisions were affected by conflict. We find that women living in clusters accounting for a larger proportion of sibling deaths in 1994, the year of the genocide, were more likely to marry later and have children later compared with those living in clusters accounting for a lower proportion of sibling deaths. Women living in regions with higher levels of under-five mortality were more likely to have their first child earlier compared with women living in regions with lower infant mortality. The age at marriage was probably affected by two reasons: the change in age structure and sex ratio of the population following the genocide, and the breakdown of kinship in the case of women who lost their siblings.     

Unconditional Forgiveness, Reconciliation Sentiment, and Mental Health Among Victims of Genocide in Rwanda

The study assessed the relationships between mental health (loss, anxiety and depression), reconciliation sentiment (intra personal and interpersonal reconciliation sentiment), and dispositional forgiveness (lasting resentment, sensitivity to circumstances and unconditional forgiveness) among Rwandese survivors of the 1994 genocide. A sample of 72 females and 29 males living in the southern province of Rwanda, primary victims of the genocide (widows or children of killed people), was presented with questionnaires measuring these constructs. As hypothesized, (a) a strong, positive association was found between interpersonal reconciliation sentiment (trust and cooperation) and unconditional forgiveness, and (b) no significant associations were found between interpersonal reconciliation sentiment and the other two factors of the forgivingness construct: lasting resentment and sensitivity to circumstances. This pattern of associations was consistent with the view that, owing to the current situation in Rwanda where very few perpetrators have directly apologized, the only way for the victims to achieve a state of forgiveness is through unconditionally forgiving the people who harmed them.     

Reconciliation Sentiment Among Victims of Genocide in Rwanda: Conceptualizations,and Relationships with Mental Health

In two studies that were conducted in Rwanda, we have examined the conceptualizations held by people who have experienced genocide with regard to reconciliation sentiment and quantitatively assessed the relationship between reconciliation sentiment and mental health. It was found that the participants have articulated conceptualizations regarding the nature of reconciliation sentiment. These conceptualizations are consistent with the way the genocide victims personally experienced reconciliation. More importantly, one type of reconciliation sentiment (the one corresponding to a renewed capacity to live together, hear each other, work together, and to forge compromises on a daily basis) was associated with mental health.     

The Intergenerational Effect of Cambodia's Genocide on Children's Education and Health

We investigate the intergenerational impact of conflict on the educational and health outcomes of children born years after the conflict ended by exploiting geographical variation in the intensity of the genocide that occurred during the Khmer Rouge (KR) regime in Cambodia. We find that children of individuals who were of prime marriage age during the genocide and experienced greater intensity of genocide have worse educational and health outcomes. In particular, for each standard deviation increase in the intensity of the genocide, average children's normal grade progression rate decreases by 0.03 standard deviations and average children's height‐for‐ age Z‐score decreases by 0.06 standard deviations. We examine several channels through which genocide could affect children born to survivors after the conflict and find suggestive evidence that the marriage market acts as a channel that transmits the adverse impact of conflict across generations. Our findings are robust to alternative measures of mortality rates and post‐KR internal migration.     

珠三角非户籍人口的职业与社会融合实证分析

本文采用专项问卷调查的数据,通过多种统计方法来分析职业变量在非户籍人口社会融合过程中的作用。研究发现,职业与个体社会融合程度密切相关,处于职业高层人员的整体社会融合程度较高;相对于蓝领职业群体而言,白领职业群体的融合程度较高,且个体之间融合程度的差异较大;性别和年龄与职业的交互效应对社会融合的影响是显著的;人口变量对蓝领群体的社会融合不存在显著影响,然而年龄和代际变量对白领群体的社会融合存在显著影响。作为夹层群体的非户籍白领人员,他们的社会融合更应该得到关注,且应该成为促进融合的优先考虑群体。     

Some population characteristics of villages differentiated by size,location, and growth

Selected social characteristics of individuals were examined for groups of villages simultaneously dichotomized by size, location relative to larger cities, and population change. The percent of people having a selected characteristic in each village group of the resulting eight-fold classification was taken as the dependent variable, and difference scores indicating main effects and first order interactions were obtained for each characteristic. The universe is the 375 incorporated places under 2500 in 1950outside the SMSAs of Wisconsin. Size of place was found to be important for the sex ratio, education and income levels, and labor force and occupational variables. Characteristics associated with nearness to a large city included income, male labor force participation, occupation, and industry. Growth was important for age and sex differences, education, income, and some labor force, occupation, and industry variables. An interaction between location and growth was found for several occupation and industry characteristics. The consistency between some of the results and previous research on larger places supports the contention that villages, although classified as rural, share many characteristics of urban centers. The industry and occupation differences by location, and the interaction between location and growth, strongly suggest that location is tied closely to function here. Places near cities over 25,000, especially those that are growing, may serve as residences for commuting blue-collar workers, or perhaps as small manufacturing centers, while most places more remote from cities continue to function as small service centers for a rural hinterland.

The socio-demographic legacy of the Khmer Rouge period in Cambodia

Passages funded by Australia's colonial governments accounted for 56 per cent of all arrivals from the United Kingdom between 1831 and 1860. In concert with a range of private, Colonial Office, and Poor Law sources in the UK, analysis of data on the emigrants' age, sex, occupation, county of origin, literacy, and religious persuasion, collected by colonial Immigration Agents, challenges the traditional view of Australia's government immigrants. Rather than indigent misfits, shovelled out by a system anxious to rid the UK of its poor, they were primarily well-informed, self-selecting, literate individuals who often sought help from philanthropic agencies or their local parish to enable them to finance their passage deposit, mandatory clothing, and travel to the port of embarkation. Comparative analysis of data on occupation and county of origin, which suggests that they were not the spillover of the North America-bound streams, further challenges the prevailing view.     

对2000年人口普查出生性别比的分层模型分析

本文对以往出生性别比研究中的若干观点进行了学术评论,并讨论了个别经验统计分析中的方法问题。在此基础上,本文应用非线性分层模型将2000年全国人口普查1‰数据和1999年的地区级生育政策数据结合起来对出生性别比失调的影响因素进行了初步分析。结果表明,育龄妇女现有子女数量及性别和一些社会特征对出生性别比存在单独的影响,并且肯定了生育政策既存在对出生性别比的直接影响,也通过其与妇女以往生育结果以及其他社会特征之间的交互效应来影响出生性别比。

A cohort analysis of the fertility of the July 1 People's Commune in Shanghai, County]

The survey was conducted in February-March 1981. The population of this commune at the end of 1980 was 18,608. The cultural and educational levels, economic condition, and work in family planning of this commune form a typical example among numerous similar communes in Shanghai County. The birthrate, natural growth rate, and average fertility rate began to decline in the later half of 1950s and reached the lowest level in 1974. The survey shows a delay in the marriage age. The fertility rate also dropped by 21.31% from 1963 to 1980. The average fertility rate dropped by 162.73% from 1963 to 1980. Among the women of childbearing age, 99% of them have a knowledge of birth control measures, 95% of them have used them before, and 78% are currently using them. All these figures show that the work in family planning in the commune has reached a high level by world standards. 3 factors which have a strong impact on fertility are: the economic and educational level, formation of population elements, and family planning work. A rise in the standard of living and improvement in education normally leads to late marriage and a decline in fertility. An increase in the number of women of childbearing age causes a rise in fertility. The population growth after 1974 is a reflection of this situation. The survey shows that the decline in fertility before 1973 was caused mainly by family planning work.     

Survey sheds new light on marriage and sexuality in the Philippines

The Young Adults Fertility and Sexuality Study (YAFS-II) was conducted in 1994 by interviewing 10,879 men and women aged 15-24 years in households on dating, marriage, and onset of sexual activity in the Philippines. In addition, screening data were collected on all households visited and on the 959 sampled local communities. Direct questions on premarital sex revealed that at least 52% of married women had sex before marriage. Among married respondents, 57% of men and 51% of women reported having had sex with their spouse before they were married. Only 3% of the women had additional premarital partners vs. 37% of the men. Questions on premarital sex and social patterns showed that about 20% of the single women and 28% of the single men had been in a serious relationship by the time they were 17. By age 20, 44% of the single women and 63% of the single men had been in a serious relationship, while the respective figures by age 24 were 60% and 68%. Altogether 24% of the women and 10% of the men described themselves as married. 34% of all women who either eloped or lived with their spouses had been married in church by the time of the survey, 23% had had civil ceremonies, and 41% designated their marital status as cohabitation. With regard to the risk of HIV/AIDS and other sexually transmitted diseases, 25% of the 24-year old men who never had a girlfriend reported sexual experience and 22% of those still single at age 24 reported that they had visited a commercial sex worker. Marital status was not the best basis for providing family planning services, and the provision of reproductive health services to young people living in consensual union would reduce accidental pregnancy.     

What Will You Do If I Say ‘I Do’?: The Effect of the Sex Ratio on Time Use within Taiwanese Married Couples

This paper uses the natural experiment of a large imbalance between men and women of marriageable age in Taiwan in the 1960s to test the hypothesis that higher sex ratios lead to husbands (wives) having a lower (higher) share of couple’s time in leisure and higher (lower) share of the couple’s total work time (employment, commuting, and housework). The sample includes 18,134 Taiwanese couples’ time diaries from 1987, 1990, and 1994. The OLS analysis finds evidence of the predicted effects of the county-level sex ratio on husbands’ and wives’ share of leisure and total work time. The county-level sex ratio’s impact on college-educated husbands’ time use is shown to be larger than the impact on non-college-educated husbands’ time use. A two-stage least square analysis controlling for possible endogeneity of county of residence returns similar findings.     

In-vehicle fatalities,seat belts,and compulsory seat belt legislation: The Manitoba experience

Using medical data from the Medical Officer of Health (MOH) the paper presents an exploratory mutivariate statistical analysis of in-vehicle mortality in Manitoba, 1983–85. It is found that total mortality had increased in excess of 31% following the introduction of compulsory seat-belt legislation in April, 1984. It is also found that in-vehicle mortality is related to average age of drivers/occupants, sex of victims, blood alcohol level, and in some cases seat-belt use. Since the data represents a chronological series it is not possible to disentangle the physical effect of seat-belts and the compulsory seat-belt legislation.     

Pitfalls in comparing immigrants with the Australian-born population with particular reference to socioeconomic status

With the increasing interest in the impact of immigration on the character of the Australia’s population it is useful to draw attention to the differences that can occur when comparisons of the immigrant and the host population with respect to socioeconomic status are based on aggregate rather than on disaggregate measures. In this paper the discussion focuses on the implications of not disaggregating by age and sex, with respect to such variables as: post-school qualifications, occupation, and labour-force participation, using the total overseas-born population in Australia as an example. The analysis demonstrates the fact that the different age structures of the immigrant and the host populations can result in deficiencies in the aggregate rates.     

Consideration of future consequences and unprotected anal intercourse among men who have sex with men

This study of men who have sex with men (MSM) examined whether tendencies to consider the future consequences of one's actions were associated with sexual behaviors that place oneself at risk for HIV infection. A total of 339 HIV-negative MSM responded to the Consideration of Future Consequences Scale (CFC; Strathman et al., 1994) and to questions about their anal intercourse practices in the past year. In bivariate analyses, men with a stronger future orientation were less likely to engage in anal intercourse unprotected by a condom (p < .05). Multivariate analyses revealed that CFC accounted for significant variance in three of four measures of unprotected anal sex after statistically controlling for demographic covariates (education, income, ethnicity, age). CFC was a better predictor of sexual behavior and accounted for more unique variance than any of the demographic factors. Additional research is needed to confirm that CFC is an antecedent of behavior and to examine the feasibility and efficacy of focusing on CFC in HIV prevention interventions.     

Is 60 the New 50? Examining Changes in Biological Age Over the Past Two Decades

Increasing life expectancy has been interpreted as improving health of a population. However, mortality is not always a reliable proxy for the pace of aging and could instead reflect achievement in keeping ailing people alive. Using data from NHANES III (1988–1994) and NHANES IV (2007–2010), we examined how biological age, relative to chronological age, changed in the United States between 1988 and 2010, while estimating the contribution of changes in modifiable health behaviors. Results suggest that biological age is lower for more recent periods; however, the degree of improvement varied across age and sex groups. Overall, older adults experienced the greatest improvement or decreases in biological age. Males, especially those in the youngest and oldest groups, experienced greater declines in biological age than females. These differences were partially explained by age- and sex-specific changes in behaviors, such as smoking, obesity, and medication use. Slowing the pace of aging, along with increasing life expectancy, has important social and economic implications; thus, identifying modifiable risk factors that contribute to cohort differences in health and aging is essential.     

The socio-demographic legacy of the Khmer Rouge period in Cambodia

The study presented in this paper is an examination of the long-term impact of genocide during the period of the Khmer Rouge regime (1975-79) in Cambodia. The very high and selective mortality of the period had a major impact on the population structure of Cambodia. Fertility and marriage rates were both very low under the Khmer Rouge, but recovered immediately after the regime's collapse. Because of the shortage of eligible men, the age and education differences between partners tended to decline. The period also had a lasting impact on the educational attainment of the population. The school system collapsed during the period and therefore individuals -- especially men -- who were of school age at the time have a lower educational attainment than those from the preceding and subsequent birth cohorts.
