This article examines the impact on children's education and labour of monthly cash grants targeted on ultra‐poor households and designed to reduce poverty and enable families to invest in human development. It conducts a randomised community trial, with baseline and endline surveys of intervention and control households; verifies school enrolment; and completes key‐informant interviews and focus‐group discussions. Compared with non‐beneficiaries, intervention children experienced a 5 percentage point difference in enrolment, higher educational expenditures, fewer absences, and a 10 percentage point decrease in labour outside the home. Qualitative data confirm the quantitative findings. Transfers to poor households had a positive impact. However, the Malawian educational system needs to be improved for short‐term impacts to lead to long‐term development in human capital. 相似文献

农村劳动力转移就业的多元路径选择 总被引:1,自引:0,他引:1
长期以来,我国农村劳动力转移就业基本上是以流向东部沿海经济发达地区为主的单一模式。近年来,受东部沿海地区产业向中西部地区转移进程加快和内地经济快速发展的影响,区域间的比较优势逐渐弱化,农村劳动力远距离就业的选择空间越来越大,当地政府必须通过调整农业经济结构、鼓励农民自主创业、加大招商引资力度和开辟国外劳务市场等途径探索多元转移就业路径,实现农村劳动力合理转移就业。 相似文献

Can the minimum living standard guarantee scheme enable the poor to escape the poverty trap in rural China? 下载免费PDF全文
The rural Minimum Living Standard Guarantee (Dibao) Scheme is the most important social assistance programme in rural China. However, how the rural Dibao programme affects household expenditures and whether it can enable the poor to escape the poverty trap are questions that remain largely unexplored. This study used data from the 2012 Rural Household Survey in China to investigate the impact of the rural Dibao programme on household expenditures. We found that the programme significantly improved the well‐being of low‐income households. Particularly, the programme significantly increased household expenditures on housing, education and health; furthermore, the impact was greater for households with educated household heads. However, the programme did not significantly affect household expenditures on food, transportation or farming inputs. The results imply that participation in the rural Dibao programme induces household investment in human capital, which could help to break the inter‐generational transmission of poverty and raise long‐run welfare. 相似文献

Background
Meconium stained amniotic fluid commonly occurs postdates (?>40 weeks gestation) indicating fetal maturity. Previous literature indicates that different ethnicities mature at different rates.Aim
To compare the rate of meconium stained amniotic fluid of Australian-born and non-Australian born women.Methods
A retrospective correlation study design was implemented, using data collected in the birth outcomes system at one tertiary hospital. Data was collected from all women who gave birth to a term (>/=37 weeks gestation), singleton, liveborn baby between January 1st to December 31st, 2014. Maternal country of birth was used for comparison. Categorical data was analyzed using Chi-Square test for Independence. Continuous variables were assessed for normality, and differences were compared using an Independent t-test or a Mann–Whitney U test. All tests were two-tailed and p < 0.05 was considered statistically significant.Results
3,041 women were included; 1131 Australian-born and 1910 non-Australian born. Meconium stained amniotic fluid occurred more frequently in non-Australian born women compared to Australian-born women (23.5% vs. 19.8 p = 0.02). Their babies were significantly smaller (Mean = 3265 g, Standard Deviation 463.8 vs Mean = 3442 g, Standard Deviation 499.2, p < 0.001), with no difference in gestational length (Mean = 39.4, Standard Deviation 1.28 vs Mean = 39.5, Standard Deviation 1.18, p = 0.06). Increasing gestational age had the strongest association with meconium stained amniotic fluid;?>/=42 weeks gestation occurring 3.52 (95% Confidence Interval: 2.00, 6.22, p = <0.001) more than <40 weeks gestation.Conclusion
Maternity health services should record ethnicity and region of birth to provide individualised care as women born overseas often have poorer perinatal outcomes when compared to Australian-born women. 相似文献65.
土地流转是实现规模化经营的前提之一,然而土地流转中却出现大量小农复制,从而影响土地流转的质量和效果。运用12省(自治区)2 553份农户问卷,详细分析土地流转中小农复制的现状及其形成原因。研究发现:(1)农户流转耕地面积不大,转入户流转面积20亩及以下的约占总转入户数的60.3%,转出户流转面积5亩及以下的约占总转出户数的74.38%,转出户中仍然经营土地的约占总转出户数的74%。(2)农业分工发达使生产更加方便、文化传统形成路径依赖、禀赋效应产生“价值幻觉”以及公共服务不健全使未来存在不确定性导致转出户流转部分土地。乡土社会限制土地流转范围和经营风险增加风险感知导致转入户流转小规模土地。 相似文献

当前中国以异地化转移的城镇化模式已暴露出众多的问题,这种以人口非家庭式迁移和异地转移为主要特点的城镇化发展模式不可持续,必须予以改变。通过对中国第三条农村城镇化道路进行探索可知,以企业战略推动的统筹发展型就地城镇化模式能够弥补前两条道路的不足,可以实现整村、全家同步转移,农民到市民一步的转换,具有多元正效应。在就地转移的第三条道路中,个体的搜寻成本、心理成本、交通成本和住房成本明显低于第二条道路中相应的成本,而生活成本和学习成本则相差不大。将个体劳动供给经典模型进行扩展可知,当工作时间相同时,第三条道路的劳动者个体拥有较高的实际收入和效用水平;从家庭效用模型中也可发现,家庭部门愿意提供的就地转移劳动数量要多于异地转移劳动数量,其更倾向于第三条道路下的就地转移方式。 相似文献

This paper documents the experience of developing and teaching a course on mental health for undergraduate social worker students during a semester in Vietnam. Social work is a profession at the early stages of development in Vietnam, requiring much curriculum development. There are over 40 universities with undergraduate social work education programs, but few of the faculty have had training or experience in practicing social work. The paper will summarize the main reasons for developing such a course given the current state of mental health need and services in a changing culture, as well as the current state of professional social work education and the newly established profession of social work. The author describes the contexts underlying the course—the status of social work and social work education in Vietnam, the context of mental health and mental illness in Vietnam, and curriculum adaptation to the cultural context. From this experience, the lessons learned about the role of cross-cultural critical thinking, cultural knowledge, and other strategies will be discussed about teaching a subject like mental health internationally. 相似文献

整体性是马克思主义理论的重要特性,整体性问题是研究马克思主义的一个基本问题,也是当前我国学者研究马克思主义的一个热点问题。我国理论界围绕此问题进行了深入而系统的研究,取得了丰硕成果,但也存在一些问题,对这些问题的反思,有益于进一步实现马克思主义整体发展和创新的前瞻性使命。 相似文献
