The revitalization of Ethiopian higher education (HE) has been underway since the early 2000s. As well as the economic optimism evident in the ‘knowledge-driven poverty reduction’ discourse, social equity goals underscore the reform and expansion of the system. Notwithstanding the widening participation and the equity policy provisions put in place, the problem of inequality has persisted along the lines of ethnicity, gender, rurality and socio-economic background. This paper reviews major equity policy instruments and highlights the enduring inequalities in Ethiopian HE. It argues that this persistence is related in part to the ways in which the problem is represented in policy, and that redressing the problem necessitates framing inequality as capability deprivation rather than as issues of access and disparities in enrolment.  相似文献

Many countries use centralized school choice procedures to assign pupils to schools. To address excess demand for a particular school, ties are broken according to priority points granted based on various criteria, such as proximity to the school. Using a unique reform undertaken in Madrid (Spain), we estimate the impact of abolishing residence-based priorities on families’ school choices, the stated motivation for choosing a school, and the final school allocation. Utilizing several administrative datasets on school applications, we find that the reform increases families’ out-of-district school assignments and assignments to schools further away from their home address. Parents of immigrant children did not change their application behavior in the first years of the reform but caught up with natives three years after its implementation. Children generally accessed slightly better-performing schools, particularly those from lower-educated backgrounds.  相似文献

This article investigates to what extent scholarships are unequally distributed among students in Germany and how these inequalities can be explained. Following sociological theory, the article argues that elites seek qualitative ways of distinguishing themselves in a mass higher education system. Using student surveys, we demonstrate that class effects cannot merely be explained with reference to class differences in academic achievement but that higher classes have better access to scholarships independent of earlier school performance. Class differences were particularly persistent when the intermediate classes were compared with higher classes with more education. These findings illustrate that social classes have different strategies when it comes to participating in higher education and suggest that information about and access to scholarships is important in gaining a class advantage.  相似文献

While the existence of a class, gender, or ethnic gap in educational attainment is well documented for many societies, how the practice of grade retention contributes to these patterns of educational inequality has been inadequately addressed. Given that grade retention is commonly practised in Macao, Macao is used as a case for illustration. Using data from PISA 2009 and a qualitative research project, we seek to demonstrate how inadequate state regulation could make possible the manipulation of grade retention institutionally and individually in Macao. This, in turn, illustrates how the specific contextualized structural operation of grade retention could serve as a mechanism for social differentiation and thus play a role in contributing to the observed educational inequality.  相似文献

两阶段相结合的广义投影类算法   总被引:3,自引:0,他引:3  
简金宝 《科技通报》1994,10(4):209-213
讨论了非线性不等式约束最优化问题,利用一种新的广义投影技术建立问题的一类算法,该算法的初始点可任意选取,且能自动地将初始化和最优化两阶段统一起来。算法不但无需作任何转轴运算,而且只采用ε-约束集内函数梯度确定广义投影阵,方法结构简单,计算量小,具有普遍意义。  相似文献

Following calls for further research in education inequality beyond input and output measures, especially with a qualitative approach, and building on the implications of capability deprivation on equality (0375 and 0380), we extend the findings of 0305, 0310, 0315 and 0320 capability approach to higher education (HE). This article employs social exclusion theory as the analytical framework to examine educational inequalities in China posed by the HE admission system in Post-Mao era. This paper is driven by certain key motivations and makes a significant contribution to the extant literature. Firstly, the paper seeks to outline a usable definition of social exclusion in the context of HE enrolment. Following this, 0305, 0310, 0315 and 0320 capability approach is adopted for the first time as a theoretical construct to examine the situation facing HE in China. Sen's approach facilitates an appraisal of the process of exclusion in HE enrolment. The importance of the capability approach is that it allows one to recognize different needs and choices confronting different social groups by distinguishing between different types of social exclusion in this area. Finally, this information is used to evaluate responses which are available to the existing issues within the current Chinese HE enrolment mechanism i.e. that the mechanism is fundamentally flawed and risks reducing, rather than enhancing, capability by excluding certain groups of students from fair competition in terms of access.  相似文献
