This paper offers evidence on the sensitivity of child poverty in South Africa to changes in the adult equivalence scale (AES)
and updates the child poverty profile based on the Income and Expenditure Survey 2005/06. Setting the poverty line at the
40th percentile of households calculated with different AESs the scope and composition of child poverty are found to be relatively
insensitive to the scale used. The rankings of children of different ages, girls versus boys, racial groupings and children
living in rural versus urban areas are unaffected by choice of AES, although some provincial rankings on the poverty headcount
measure are. The proportions of children and households ‘correctly’ identified as poor for the full range of scales is extremely high.
These findings support the argument that it may be appropriate for profiling poverty in South Africa to use a poverty line
based on a per capita welfare measure. For the construction of the child poverty profile, per capita income is used as the
welfare indicator with the poverty line set at the 40th percentile of household. The profile suggests that poverty amongst
children is more extensive than amongst the population or adults even after the massive injection of transfers into households
with poor children through the child support grant. The child poverty headcount, depth and severity are all highest amongst
children age 0–4 and lowest amongst those aged 15–17, who are not yet beneficiaries of the grants. They are also highest amongst
African and Coloured children. Large variations across provinces remain. The analysis underlines the importance of prioritising
children in the fight against poverty, particularly in their earliest years. 相似文献

PURPOSE: We need solid estimates of maternal mortality rates (MMR) to monitor the impact of maternal care programs. Cambodian health authorities and WHO report the MMR in Cambodia at 450 per 100,000 live births. The figure is drawn from surveys where information is obtained by interviewing respondents about the survival of all their adult sisters (sisterhood method). The estimate is statistically imprecise, 95% confidence intervals ranging from 260 to 620/100,000. The MMR estimate is also uncertain due to under-reporting; where 80-90% of women deliver at home maternal fatalities may go undetected especially where mortality is highest, in remote rural areas. The aim of this study was to attain more reliable MMR estimates by using survey methods other than the sisterhood method prior to an intervention targeting obstetric rural emergencies. PROCEDURES: The study was carried out in rural Northwestern Cambodia where access to health services is poor and poverty, endemic diseases, and land mines are endemic. Two survey methods were applied in two separate sectors: a community-based survey gathering data from public sources and a household survey gathering data direct from primary sources. FINDINGS: There was no statistically significant difference between the two survey results for maternal deaths, both types of survey reported mortality rates around the public figure. The household survey reported a significantly higher perinatal mortality rate as compared to the community-based survey, 8.6% versus 5.0%. Also the household survey gave qualitative data important for a better understanding of the many problems faced by mothers giving birth in the remote villages. There are detection failures in both surveys; the failure rate may be as high as 30-40%. PRINCIPLE CONCLUSION: Both survey methods are inaccurate, therefore inappropriate for evaluation of short-term changes of mortality rates. Surveys based on primary informants yield qualitative information about mothers' hardships important for the design of future maternal care interventions. 相似文献

Compared to other countries that have suffered from the Nazioccupation, the destructive impact of the Holocaust on theJewish population has been particularly strong in the Netherlands. This paper gives a demographicreconstruction of the Jewish population in the Netherlands by the end of the war (1945),disaggregated by age and sex. The reconstruction is based on two approaches: a forwardprojection 1941–1945, starting from registration data supplemented by information onHolocaust losses; and a backward projection 1966–1945, starting from an enumerationof Halachic Jews carried out in 1966. The two approaches yieldtwo estimates that are comfortingly similar. 相似文献

The present research examined whether the emotions of others (i.e., disappointment versus happiness with respect to a received outcome) influence own self-esteem when being overpaid. Results from two experiments demonstrated that participants reported higher performance self-esteem when the other expressed happiness rather than disappointment. This effect was only found in the condition where one was overpaid relative to the condition where one did not yet know one’s own outcome. In the second experimental study we further found that this interaction between the emotion of the other and the distribution situation only emerged among participants low (relative to high) in personal need for structure. Implications with respect to the relationship between overpayment and self-esteem and the interpersonal effects of emotions in this process are discussed. 相似文献

This paper explores the antecedents, experiences and consequences of marginalization as reported and dealt with by disabled Iranian immigrants in Belgium. This work extends the work of Gallie and colleagues and Siegrist demonstrating that the forces of marginalization applicable to all immigrants are particularly pertinent to disabled immigrants. The research is based on 26 in‐depth, face‐to‐face interviews, focus groups, interviews with government officials and immigration experts, ethnographic work and official government statistics. The findings detail how the combined forces of history, context and reasons for immigration; isolation, vulnerability and perceived loss of control; religion and rejection; lack of reciprocity in social exchanges; problems in obtaining jobs; and difficulties in negotiating an entry into Belgian society combine to sustain marginizalation. As a consequence, disabled immigrants in this group are generally excluded from society and discriminated against in terms of citizenship, education, jobs and general acceptance. 相似文献

This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9–12 (ages 13–20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the “red” category indicating a severe problem and an additional 3.3% scored in the “yellow” category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = ?0.19), lower school marks (r = ?0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents. 相似文献

In this paper, we re-analyze data from a large-scale field experiment (N = 344,084) on voter turnout in order to determine whether men and women respond differently to social pressure aimed at voter mobilization. To date, there have been mixed results regarding the interaction between a person’s gender and receptivity to social influence. On the whole, our analyses confirm prior findings that social pressure increases voter turnout but uncover little to no evidence of gender differences in receptivity to social pressure cues in the context of political participation. 相似文献

Estimates of subgroup treatment effects in overall nonsignificant trials: To what extent should we believe in them? 下载免费PDF全文

In drug development, it sometimes occurs that a new drug does not demonstrate effectiveness for the full study population but appears to be beneficial in a relevant subgroup. In case the subgroup of interest was not part of a confirmatory testing strategy, the inflation of the overall type I error is substantial and therefore such a subgroup analysis finding can only be seen as exploratory at best. To support such exploratory findings, an appropriate replication of the subgroup finding should be undertaken in a new trial. We should, however, be reasonably confident in the observed treatment effect size to be able to use this estimate in a replication trial in the subpopulation of interest. We were therefore interested in evaluating the bias of the estimate of the subgroup treatment effect, after selection based on significance for the subgroup in an overall “failed” trial. Different scenarios, involving continuous as well as dichotomous outcomes, were investigated via simulation studies. It is shown that the bias associated with subgroup findings in overall nonsignificant clinical trials is on average large and varies substantially across plausible scenarios. This renders the subgroup treatment estimate from the original trial of limited value to design the replication trial. An empirical Bayesian shrinkage method is suggested to minimize this overestimation. The proposed estimator appears to offer either a good or a conservative correction to the observed subgroup treatment effect hence provides a more reliable subgroup treatment effect estimate for adequate planning of future studies. 相似文献

Objective: Drinking alcohol during the exams can affect academic performance and future career options, but is rarely investigated. Drinking motives, sociodemographics and personality characteristics are investigated in nonabstainers and weekly drinkers during the exams. Participants: 7,181 Belgian university students who anonymously responded to an email invitation to an online survey. Methods: Logistic regressions and mixed design analysis of variance on cross-sectional data. Results: One-third of the students continued drinking during the exams, with 40% drinking weekly. Nonabstainers were mainly men, elder, internally motivated when drinking, and housed with parents or independently. Weekly drinkers were similar, except mainly housed in student apartments or independently. Personality characteristics were nonsignificant. All drinking motives were less pronounced during the exams, with smaller differences for internal motives. Conclusions: Mainly linked to internal drinking motives, drinking during the exams in higher education is underestimated. The characteristics and motives of students doing so can be used in future interventions. 相似文献

Currently, disabilities organizations are increasingly being challenged by the requirement for individualized service, expectations to show personal outcomes, and the need to base their services on evidence-based practices. Social entrepreneurship (SE) is being put forward as an innovative approach for dealing with these challenges. This article presents a systems approach to SE based on a program logic model. This model identifies the input factors (a strong social vision, exploiting opportunities, maximizing resources), throughput strategies (entrepreneurial orientation, critical thinking skills, networking, capacity building), and outcome components (improving people’s lives, community-building, improving society) of SE at the micro, meso, and macro level. Also, the importance of planning for contextual changes as a social entrepreneur is discussed. The article concludes with presenting three inspiring practices regarding SE in the field of disabilities organizations. 相似文献
