The socio-economic literature has focused much on how overall inequality in income distribution (frequently measured by the Gini coefficient) undermines the “trickle down” effect. In other words, the higher the inequality in the income distribution, the lower is the growth elasticity of poverty. However, with the publication of Piketty’s magnum opus (2014), and a subsequent study by Chancel and Piketty (2017) of evolution of income inequality in India since 1922, the focus has shifted to the income disparity between the richest 1% (or 0.01%) and the bottom 50%. Their central argument is that the rapid growth of income at the top end of millionaires and billionaires is a by-product of growth. The present study extends this argument by linking it to poverty indices in India. Based on the India Human Development Survey 2005–12 – a nationwide panel survey-we examine the links between poverty and income inequality, especially in the upper tail relative to the bottom 50%, state affluence (measured in per capita income) and their interaction or their joint effect. Another feature of our research is that we analyse their effects on the FGT class of poverty indices. The results are similar in as much as direction of association is concerned but the elasticities vary with the poverty index. The growth elasticities are negative and significant for all poverty indices. In all three cases, the disparity between the income share of the top 1% and share of the bottom 50% is associated with greater poverty. These elasticities are much higher than the (absolute) income elasticities except in the case of the poverty gap. The largest increase occurs in the poverty gap squared – a 1% greater income disparity is associated with a 1.24% higher value of this index. Thus the consequences of even a small increase in the income disparity are alarming for the poorest. 相似文献

We present an algorithm for learning oblique decision trees, called HHCART(G). Our decision tree combines learning concepts from two classification trees, HHCART and Geometric Decision Tree (GDT). HHCART(G) is a simplified HHCART algorithm that uses linear structure in the training examples, captured by a modified GDT angle bisector, to define splitting directions. At each node, we reflect the training examples with respect to the modified angle bisector to align this linear structure with the coordinate axes. Searching axis parallel splits in this reflected feature space provides an efficient and effective way of finding oblique splits in the original feature space. Our method is much simpler than HHCART because it only considers one reflected feature space for node splitting. HHCART considers multiple reflected feature spaces for node splitting making it more computationally intensive to build. Experimental results show that HHCART(G) is an effective classifier, producing compact trees with similar or better results than several other decision trees, including GDT and HHCART trees. 相似文献

This article demonstrates the utility of a new source, prison registers, for the history of literacy and education in nineteenth-century England. It focuses on two sets of prison registers from the two county gaols in Suffolk, located at Ipswich and Bury St Edmunds, which contain personal information on 16,690 individuals over the period 1840 to 1878. First, the article examines the context in which personal information about prisoners was recorded and tests the data against benchmarks from other sources to prove its reliability. Second, the article employs two methods, statistical analysis and digital mapping, to study in depth the rich data on prisoners’ literacy and schooling. Finally, the article shows how the results of this analysis significantly revise our understanding of the prevalence of schooling among the labouring poor, the use of different types of schools, the role of the partially literate in the drive towards mass literacy, and the importance of life-long learning. 相似文献

As U.S. manufacturing and production industries have declined, the growth of the care sector has increasingly become an important source of jobs for workers without a college degree. Often requiring some form of postsecondary credentialing, many care occupations can provide better wages, job stability, and possible upward mobility for less educated workers. However, employment patterns in paid care work are both gendered and racialized: women and workers of color are overrepresented in care occupations with fewer entry barriers, benefits, and lower pay. Although these patterns are well documented, the mechanisms producing them are less well understood. Using event history analysis and the National Longitudinal Survey of Youth (NLSY79), this study evaluates the explanatory power of neoclassical economic, status attainment, and social closure theories of occupational segregation for black women’s and men’s greater hazard or “risk” of entering care occupations, relative to white workers. Net of individual and closure mechanisms, significant residual effects suggest labor market discrimination remains a primary explanation for the over-representation of black workers in less credentialed care jobs with fewer benefits. 相似文献

Faculty mentorship is a highly advantageous yet under-explored form of social capital which can grant access to co-curriculars (e.g., research assistantships), ensure strong letters of recommendation, and more. It is also typically informal and dependent on student initiative, requiring that students be skilled at engaging educational authority figures. Privileged students are most likely to have such skills as part of their dominant cultural capital, making faculty mentorship a site of social reproduction. To explore variations in this process, I compare two institution types: a small, teaching/undergraduate-focused regional university and a large, research-intensive flagship. In interviews with 68 working- and upper-middle-class students, I find that college context mediates the relationship of class background and faculty mentorship. Upper-middle-class students fostered advantageous faculty relationships at both universities, but working-class students diverged: at the flagship, they rarely approached professors in search of mentorship, while those at the regional university described close, beneficial connections with professors. I discuss working-class students’ dissimilar experiences in terms of each university’s structural and cultural characteristics (organizational habitus), particularly their institutional focus and size. I argue that through their particular organizational features, colleges can both reproduce and reduce inequalities, challenging the determinacy of precollege socialization in education. 相似文献

The paper evaluates spatial, behavioural, and material signalling of social class in African contexts, focusing on Kenya and Zambia. In particular, it draws on notions of mode of class signalling and intersectionality and a vignette of an interaction between urban‐based Western educated development agents and local participants in rural Kenya to illustrate how social class is implicated in interactions. The paper shows how significant features of class and dimensions of social inequality may be perceived intersectionally so that positionalities in class structures are negotiated in contexts of interaction, thus illustrating how structural conditions of class may be challenged and questioned. The paper concludes that sociolinguistics needs to identify the various ways in which the marginalized challenge social structures of inequality. Otherwise there is a risk that sociolinguistics will work to validate inequalities as permanent and fixed, and victims of unequal treatment as permanently condemned and never able to rise against oppressive social structures that tyrannize them. 相似文献

ABSTRACTWe develop the concept of “social movement school’ (SMS), showing how these organizational spaces are deliberately designed for purposes of educating, mentoring, training, and coordinating individuals as effective, committed movement agents. SMSs can also be important sites of prefigurative design and practice for future societal development consistent with movement goals. We motivate the theoretical significance of SMSs based on five perspectives in social movement scholarship: (1) resource mobilization; (2) cultural approaches to repertoires of contention; (3) cognitive perspective; (4) micro-mobilization; and (5) biographical consequences of participation. We then offer a typology to capture primary purposes, and spatial reach within the broad field of SMSs. Within-movement variation is illustrated by focusing on a variety of SMSs in the U.S. civil rights movement; and the cross-movement breadth of the concept is illustrated by highlighting contemporary SMS forms drawn from three very different movements–labor, radical feminism, and mindfulness meditation movements. In the interest of launching a research agenda on SMSs, we end with several key questions that could serve to guide future research. Important theoretical, empirical, and practical considerations suggest that SMSs deserve the attention of scholars and activists alike. 相似文献

This commentary critiques Betthäuser, Bourne and Bukodi's (2020) paper which finds that cognitive ability does not substantially mediate class of origin effects on educational and occupational outcomes. From these results, they conclude that cognitive ability is only of minor importance for social stratification, reasserting their view of the primacy of class origins for social stratification. The central issue surrounding cognitive ability in social stratification is its effects on socioeconomic attainments vis-à-vis socioeconomic origins, not the extent that cognitive ability mediates classorigin effects. Their analytical strategy of estimating the extent that cognitive ability mediates class origineffects is misleading because: it ignores the only moderate associations of socioeconomic origins with educational and occupational outcomes; the stronger direct effects of cognitive ability; the associations of parents’ ability with their own socioeconomic attainments; and the genetic transmission of cognitive ability and other traits relevant to social stratification from parents to their children. 相似文献
