In the current paper, we employ the most recent Programme for International Student Assessment (PISA) data to calculate a less-biased estimate of poverty on US achievement. The PISA was specifically chosen as it is an assessment removed from a specific curriculum and instead focuses on concepts that students should know in order to participate in a global economy. Using a propensity score matching approach, our findings suggest that US students in poverty have notable educational attainment deficiencies compared to a matched group of students who are not in poverty. In other words, when we select two students who have a great deal in common but for the fact that one comes from a poverty background, the student in poverty is expected to perform nearly 28 points, or about a quarter of a standard deviation lower, on the PISA assessment. In real terms, this puts math achievement for children not in poverty on-par with the Organisation for Economic Co-operation and Development (OECD) average, while children in poverty are well below the OECD average. 相似文献

While socioeconomic barriers to learning have been well-documented by education, sociology, and social policy scholars, further research is needed to understand how students with low-socioeconomic status excel in high-performing schools. The collection and analysis of 20 in-depth interviews with female college students from different racial and socioeconomic backgrounds provide rich insights into the stark differences between the educational practices of low and high-SES students. Building on Bourdieu’s conceptualization of how habitus and capital influence practices in the field of education exposes unique, strategic practices that low-SES students use to attain educational success within a system of reproduction and power. While entering a high-performing school is often perceived as a definitive step for accessing high-quality educational resources, my findings illustrate how it is actually an important intermediary step within a more complex process. Increasing educational opportunity and attainment for low-SES students requires improving their access to social, cultural, and economic capital through knowledgeable mentors who contribute to a habitus and portfolio of capital which enable practices to successfully navigate and challenge the educational system. 相似文献

International social work students in Australia have reported difficulties in finding quality placement opportunities and dealing with issues such as language and cultural barriers. While placement issues have been mostly investigated from a student perspective, this study explores the experiences and perspectives of placement educators towards supervising international social work students. It draws on an online survey of 83 placement educators working for an Australian university. The majority of placement educators reported that they supervised international students differently to domestic students. These differences were negatively framed as challenges involving students’ language competence, their understanding of cultural norms, and knowledge of Australian welfare systems. This framing implies that cultural and linguistic differences between international students and placement educators are viewed in terms of student deficiency rather than as a positive opportunity for mutual learning and professional development. 相似文献

Problem
There is lack of data on the rate of episiotomy in Lebanon and the study’s hospital.Background
Only a few studies have addressed episiotomy practice in Lebanon and the Middle East and they show varying rates.Aim
To identify the rate, and change in rate, of episiotomy practice over the years at a teaching hospital in Lebanon and to assess whether maternal age, parity, fetal weight, woman’s hospital admission class, and physician’s gender were associated with episiotomy. We also tested the association between episiotomy and postpartum hemorrhage and/or high degree perineal tears.Methods
A retrospective observational study was conducted on 1756 records for women having a normal vaginal birth at a single centre from January 2009 to January 2014.Findings
The rate of episiotomy at the hospital was very high, with 97.4% of women receiving an episiotomy in 2009. A major decrease in the rate was identified with a decline from 97.4% in 2009 to 73.3% in January 2014. Episiotomy was found to be associated with parity, maternal age, and with high degree perineal tears.Discussion
The episiotomy rate at this centre remains higher than the 10% rate recommended by the World Health Organization, although there has been a significant reduction after a call for restrictive rather than liberal use.Conclusion
Raising awareness among providers appeared to play a significant role in reducing this rate, although more efforts remain warranted. Other strategies – such as raising awareness of women about potential risks of episiotomy – are also worth exploring. 相似文献6.
The aim of this paper is to examine whether and how rural residents’ educational attainment is associated with their self-rated health in China. Taking advantage of the National Exercise Facility Survey that was collected between December 2015 and March 2016, we find that educational attainment has a significant and positive correlation with self-rated health, net of the effects of age, gender, and geographical region. This correlation is mediated by factors such as perceived importance of exercise and healthy lifestyle. Relatively, people’s cognitive knowledge about health-related information and material resource access fail to play a significant mediating role. The findings highlight the non-material and non-cognitive attributes of educational attainment in shaping the gradient of health in the rural setting of China. Interventions that expand formal education to the mass and optimize teaching contents may offer an effective means to balance the health gradient. 相似文献

As female labor force participation increases globally, the relationship between maternal employment and children's development remains unclear. Using data from the India Human Development Survey (2005), we investigate the link between maternal employment and children's arithmetic and reading achievement. We develop a work pattern typology that goes beyond standard measures of employment and captures work intensity and its compatibility with child-rearing in a transitional economy. We find that the relationship between maternal employment and children's outcomes is not unidimensional. For example, children of self-employed mothers are not disadvantaged compared to those with stay-at-home mothers, but maternal employment in salaried jobs or wage work outside the home is negatively associated with cognitive skills in children. However, this negative association is reversed at higher levels of maternal education, suggesting greater access to resources and flexibility associated with better jobs mitigate the negative aspects of maternal employment posed by time constraints. Additionally, maternal employment is associated with maternal involvement in schoolwork and financial investment in academic activities, providing evidence that both time and resources devoted to children's education are significant. 相似文献

Higher educated people tend to be more accepting of homosexuality than lower educated people. This has inspired claims that education leads to a higher acceptance of homosexuality. Alternatively, the association between education and acceptance of homosexuality could be confounded by (un)observed family background and stable individual characteristics. This study investigated the association between education and acceptance of homosexuality and the role of potential confounders in a unique longitudinal sample of British siblings. Multilevel and fixed effects analyses show that both perspectives apply. A large part of the association between education and acceptance of homosexuality could be attributed to family background and observed individual characteristics (one third), as well as unobserved individual characteristics (an additional third), but the positive association remains. Findings are discussed in light of existing explanations regarding the effect of education on the acceptance of homosexuality. 相似文献

2018 marks the 50th anniversary of Enoch Powell’s infamous ‘Rivers of Blood’ speech, an intervention that is still viewed as one of the most incendiary statements of the perceived decay and violence likely to follow legislation intended to assure minoritised British citizens of equal rights regardless of their ethnic origin. In this essay, Sally Tomlinson (one of Britain’s foremost multicultural theorists) reflects on Powell’s legacy and the contemporary scene where in the US, UK and across Europe, White resentment and fear is increasingly shaping ‘mainstream’ debates about nationhood, migration and education. 相似文献

We apply a four-stage methodology (i.e., cluster analysis, data mining, partial least square path modeling, and importance-performance analysis) to identify the critical paths to multi-dimensional prosperity of nations. Using the Legatum Prosperity Index across 142 countries as a proxy for prosperity, we find strong evidence of the positive causal mechanisms among dimensions of prosperity. This implies that individual dimensions of prosperity should not be weighted equally in designing policies that support prosperity of nations. In line with human capital theory, we find that education and the pupil to teacher ratio are the key policy drivers of prosperity enhancement. 相似文献
