We examined the association of orphanhood and completion of compulsory school education among young people in South Africa. In South Africa, school attendance is compulsory through grade 9, which should be completed before age 16. However, family and social factors such as orphanhood and poverty can hinder educational attainment. Participants were 10,452 16–24‐year‐olds who completed a South African national representative household survey. Overall, 23% had not completed compulsory school levels. In univariate analyses, school completion was lower among those who had experienced orphanhood during school‐age years, males, and those who reported household poverty. In multivariate analyses controlling for household poverty, females who had experienced maternal or paternal orphanhood were less likely to have completed school; orphanhood was not independently associated with males' school completion. Findings highlight the need for evidence‐informed policies to address the education and social welfare needs of orphans and vulnerable youth, particularly females, in South Africa. 相似文献

A current trend in risk assessment for systemic toxicity (noncancer) endpoints is to utilize the observable range of the dose-effect curve in order to estimate the likelihood of obtaining effects at lower concentrations. Methods to accomplish this endeavor are typically based on variability in either the effects of fixed doses (benchmark approaches), or on variability in the doses producing a fixed effect (probabilistic or tolerance-distribution approaches). The latter method may be particularly desirable because it can be used to determine variability in the effect of an agent in a population, which is an important goal of risk assessment. This method of analysis, however, has typically been accomplished using dose-effect data from individual subjects, which can be impractical in toxicology. A new method is therefore presented that can use traditional groups-design data to generate a set of dose-effect functions. Population tolerances for a specific effect can then be estimated from these model dose-effect functions. It is based on the randomization test, which assesses the generality of a data set by comparing it to a data set constructed from randomized combinations of single point estimates. The present article describes an iterative line-fitting program that generates such a data set and then uses it to provide risk assessments for two pesticides, triadimefon and carbaryl. The effects of these pesticides were studied on the locomotor activity of laboratory rats, a common neurobehavioral end point. Triadimefon produced dose-dependent increases in activity, while carbaryl produced dose-dependent decreases in activity. Risk figures derived from the empirical distribution of individual dose-effect functions were compared to those from the iterative line-fitting program. The results indicate that the method generates comparable risk figures, although potential limitations are also described. 相似文献

Abstract The community-level attributes of two youth HIV prevention initiatives in a single community are examined using the concepts of social capital, empowerment and critical consciousness. The school-based peer education programme and youth-initiated public clinic ‘add-on’ facility for the treatment of adolescent sexually transmitted diseases had differing experiences in terms of implementation, community acceptance, sustainability and achieving their goals. By examining the role of conscientization, networks for accessing resources and power, and community acceptability of adolescent HIV prevention, this paper describes the differing experiences of these two programmes. The paper indicates the need for true adolescent agency in challenging the social constructions of adolescent HIV risk at the social and community levels. 相似文献

Analysis of casual work in British Columbia is an important issue given that the increase in casual work has been greater
in this province than in other provinces in Canada and given that the labour market has been substantially deregulated since
2001. In this paper, we analyse how individuals’ casual employment status affects their economic security based on a specially
designed survey undertaken by the authors. We follow the ILO’s classification of the dimensions of economic security but,
based on our findings, add a further dimension—Time security—As being of particular importance to casual workers. On the basis
of these results, we analyse the policy interventions that might be necessary to increase the economic security of casual
workers, policies which we suggest can best be conceptualized as providing a “security quilt”.

The focus of this paper is on a microeconomic analysis of the annual transition rate from temporary to permanent work of individual
workers in Canada for the period 1999–2004. Given that a large proportion of temporary employment is involuntary, an understanding
of the factors associated with the transition to permanent work may inform public policy. Factors associated with the transition,
namely, human capital, household structures and labour market segmentation are analyzed using data from the Statistics Canada’s
Survey of Labour and Income Dynamics (SLID) for the period 1999–2004, limited to paid workers aged 20–64 years, excluding students. Among the key factors associated
with the transitions are younger age and low unemployment rates. The analysis adds to the Canadian and international literature
on transitions from temporary to permanent work.

The overall ‘problem’ in early accounts of science and/or medicine in China seemed to center upon whether or not China possessed
or could acquire modern Western science. However, in the twenty-first century there is now little debate over whether or not
China has science. Yet, questions and concerns about science in China linger. The ‘problem’ of science in China has moved
away from a paradigm focused on possession or capability, to that of the correct or ethical application of Chinese science
and technology. In this essay, I will argue that the shifting of the so-called problem of Chinese science reflects larger
Western concerns about the definition and control of science itself, the rise of China as an international power, and the
ability to 'compete' in a global market predicated on the creation and application of new science and technologies.
