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. 相似文献

简论“农地转非”后的土地利益分配关系 总被引:1,自引:0,他引:1
栾谨崇 《青岛农业大学学报(社会科学版)》2008,20(2):30-32
现行征地制度使“农地转非”后形成的土地利益分配关系存在着非公平性,其本质特征是失地农民权益的大量流失。为此,应在创新征地制度的基础上,通过建立合理的征地补偿和利益分享机制,对不公平的土地利益关系进行调整,最大限度地保护失地农民权益。 相似文献

劳动力市场分割对农村流动劳动力收入水平的影响——来自甘肃省十个样本村的调查与争析 总被引:1,自引:0,他引:1
近年来,劳动力外出务工已成为农民增收的一个重要途径。农村流动劳动力作为一个特殊群体,影响其收入的因素既具有居民收入的一般规律。又具有其特殊性。现有的研究一般以传统人力资本理论和收入均等化理论等为基础,来分析农村流动劳动力收入水平的影响因素。本文以甘肃省农村流动劳动力的调查数据为样本,试图从流动劳动力的人口学特征、就职行业、流动去向及工作稳定性等四个方面分析劳动力市场分割对农民工收入水平的影响。 相似文献

The positive association between moderate alcohol consumption and wages is well documented in the economic literature. Positive
health effects as well as networking mechanisms serve as explanations for the “alcohol–income puzzle.” Using individual-based
microdata from the SOEP for 2006, we confirm that this relationship exists for Germany as well. More importantly, we shed
light on the alcohol–income puzzle by analyzing, for the first time, the association between beverage-specific drinking behavior
and wages. In our analysis, we disentangle the general wage effect of drinking into diverse effects for different types of
drinkers. Mincerian estimates reveal significant and positive relationships between wine drinkers and wages as well as between
multiple beverage drinkers and wages. When splitting the sample into age groups, the “drinking gain” disappears for employees
under the age of 35 and increases in size and significance for higher age groups. We also find a “beer gain” for the oldest
age group and male residents of rural areas as well as a “cocktail gain” for residents of urban areas. Several explanations
for our empirical results are discussed in view of the likelihood that the alcohol–income puzzle is a multicausal phenomenon.

Using longitudinal data from the Fragile Families and Child Well‐being Study (N = 1,162) and the National Evaluation of Welfare‐to‐Work Strategies (N = 1,308), we estimate associations between material and instrumental support available to low‐income mothers and young children’s socioemotional well‐being. In multivariate OLS models, we find mothers’ available support is negatively associated with children’s behavior problems and positively associated with prosocial behavior in both data sets; associations between available support and children’s internalizing and prosocial behaviors attenuate but remain robust in residualized change models. Overall, results support the hypothesis that the availability of a private safety net is positively associated with children’s socioemotional adjustment. 相似文献

随着中国经济的高速增长,中国区域间贫富差距也日渐加大,在此背景下对中国城镇居民收入是否收敛进行检验并探究其影响原因十分必要。基于一个包括物质资本和人力资本投入的新古典增长模型,根据中国31个省市的1987—2013年数据,利用SDM模型和贝叶斯MCMC统计分析方法,研究城镇居民收入的收敛性问题,结果发现:中国城镇居民人均收入具有显著的空间差异,且在1987—2008年为发散、在2008—2013年以及1987—2013年为存在β收敛的变化趋势;物质资本对中国城镇居民收入增长的β收敛具有正向促进作用,而人力资本对其具有反向促进作用,增加物质资本投入有利于缩小地区收入差距,二者的不匹配可能是导致中国收入增长差距的原因。 相似文献

“Why I Can't Stand Out in Front of My House?”: Street‐Identified Black Youth and Young Adult's Negative Encounters With Police 下载免费PDF全文
This street participatory action research (Street PAR) study organized 15 residents to document street‐identified Black youth and adult's negative experiences with police in Wilmington, Delaware. Data were collected on mostly street‐identified Black men and women aged 18–35 in the forms of (1) 520 surveys, (2) 24 individual interviews, (3) four dual interviews, (4) three group interviews, and (5) extensive field observations. Forty‐two percent of survey participants reported being stopped by police in the last year. However, with the exception of being “stopped,” participants overall reported little negative contact with police at least within the past year. Chi‐square and ANOVA analyses suggest an interactional relationship exists between race, gender, and age on experiences with police. Younger Black men (18–21) were found to have the most negative contact with police. Analysis suggests a smaller, more hardened mostly male variant of the larger street community has had repeated contact with police. Qualitative analysis reveals at least two major themes: (1) disrespect and disdain for residents and (2) low motivation for working with police. Street PAR methodology was also found to be instrumental in working with local residents and the Wilmington Police Department to improve conditions between residents and police. 相似文献

Case management services for low-income couples receiving relationship education have been required by federal funding agencies. Studies examining relationship education outcomes for low-income couples have yet to address participant characteristics of those who attend case management services (e.g., distressed vs. nondistressed). Thus, this study examined the influence of baseline relationship satisfaction and demographics on attendance at case management visits for 2,628 low-income, partnered participants who attended relationship education. Findings indicated that participants who reported higher baseline relationship distress attended more family services counselor (FSC) visits. However, when we added demographics to the model, relationship distress no longer predicted FSC visits, whereas income served as a predictor for men and women, with those reporting greater monthly income attending more FSC visits. 相似文献

This article examines the determinants of household gambling expenditures in Ireland and the effects of the recession on these expenditures using a large micro data-set, the Irish Household Budget Survey (HBS). Two gambling expenditures are examined, bookmaker tote betting and spending on the national lottery. Households with an older and a less educated head of household participate in and spend more on both forms of gambling while the presence of children in the households tends to reduce participation and spending in gambling. There is also evidence to suggest that households with an unemployed head of household have a higher likelihood of participation in gambling. The recession has affected the two forms of gambling in different ways. Lottery expenditures appear resilient to the effects of the recession. This is demonstrated in the estimated expenditure elasticities in particular. Bookmaker/tote expenditures have changed from a necessity to a luxury good, while lottery expenditures have increased in their necessity status. This can be explained by the fact that playing the lottery requires less time, knowledge and risk and has potentially greater benefits attached to it in comparison to bookmaker/tote betting. During a recession these factors become much more prevalent. 相似文献

Relative to White families, Black families have been described as relying on extended social networks to compensate for other social and economic disadvantages. The presence or absence of supportive social networks should be especially relevant to young couples entering marriage, but to date there has been little effort to describe the social networks of comparable Black and White newlyweds. The current study addressed this gap by drawing on interviews with 57 first‐married newlyweds from low‐income communities to compare the composition and structure of Black and White couples' duocentric social networks. The results indicated that low‐income Black couples entered marriage at a social disadvantage relative to White couples, with more family relationships but fewer positive relationships and fewer sources of emotional support (for wives), fewer connections to married individuals, and fewer shared relationships between spouses. Black couples' relative social disadvantages persisted even when various economic and demographic variables were controlled. 相似文献
