Field of study variation throughout the college pipeline and its effect on the earnings gap: Differences between ethnic and immigrant groups in Israel

This study demonstrates the analytical leverage gained from considering the entire college pipeline—including the application, admission and graduation stages—in examining the economic position of various groups upon labor market entry. The findings, based on data from three elite universities in Israel, reveal that the process that shapes economic inequality between different ethnic and immigrant groups is not necessarily cumulative. Field of study stratification does not expand systematically from stage to stage and the position of groups on the field of study hierarchy at each stage is not entirely explained by academic preparation. Differential selection and attrition processes, as well as ambition and aspirations, also shape the position of ethnic groups in the earnings hierarchy and generate a non-cumulative pattern. These findings suggest that a cross-sectional assessment of field of study inequality at the graduation stage can generate misleading conclusions about group-based economic inequality among workers with a bachelor’s degree.     

When Working Hard Is Not Enough for Female and Racial/Ethnic Minority Apprentices in the Highway Trades

Drawing on employment records, qualitative interviews, and a survey, we explore the experiences of apprentices in the highway trades in Oregon. We demonstrate that female and racial/ethnic minority apprentices have lower rates of recruitment and retention and disproportionately face challenges with interpersonal interactions, hiring practices, and supervisory practices. Yet, we find a pervasive narrative that attributes apprentices' success to “hard work,” which contributes to the legitimacy of these inequalities. Consistent with the conceptualization of work organizations as inequality regimes, we argue that the apprenticeship system has policies, practices, and ideologies that are on the surface gender and race/ethnicity neutral, yet lead to the perpetuation of inequalities.     

Beyond Piketty: A new perspective on poverty and inequality in India

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.     

The residual effect of a growth-decay mechanism and the distributions of covariance structures

The product of two independent or dependent scalar normal variables, sums of products, sample covariances, and general bilinear forms are considered. Their distributions are shown to belong to a class called generalized Laplacian. A growth-decay mechanism is also shown to produce such a generalized Laplacian. Sets of necessary and sufficient conditions are derived for bilinear forms to belong to this class. As a generalization, the distributions of rectangular matrices associated with multivariate normal random vectors are also discussed.

社会民主主义复兴的两种模式比较

20世纪90年代在社会民主主义复兴的过程中,英国和法国由于竞选方式、政策策略等一系列方面存在显著差别,被认为是社会民主主义复兴的两种典型模式,对英国道路与法国道路的相同之处和不同之处进行比较,说明二者存在共同性和差异性的原因。     

同质异趣色彩纷呈--莫泊桑与欧·亨利短篇小说布局艺术比较

个性是创作的生命。尽管莫泊桑和欧·亨利同是短篇小说大师,都以布局的精致巧妙而著称,但他们在创作上却是各自发挥他们独有的艺术魅力,显示出其独特的创作个性和风格,两人的创作,无论是从情节的设置、结尾艺术,还是叙述方式等方面,在有着外在相似性的同时,还有着内在的相通与相异。     

“袖”在中、朝舞蹈作品中运用异同之管见

"袖"舞是东方舞蹈的一大创造."袖"的运用,除延长了人的肢体,大大扩展了身体的表现力外,还通过舞者手臂、手腕、腰腹、身肢等不同力量、不同幅度的运动,使"袖"缭绕空际,变幻着无数的形态,其传情丰富、鲜明,超过了许多表情手段."袖"的徐缓、抑扬、飘忽、回旋所产生的形式美,完全可以把人们引入一个非物质的境界之中,赋予"袖"舞以人文精神内涵和意蕴,展现了"袖"舞的魅力和光环.     

中国心理学史与中国的本土心理学研究之比较

中国的本土心理学和中国心理学史研究既有区别,又有联系。中国的本土心理学以内发性本土化原则为指导,以中国人的心理行为和本土的传统心理学为研究对象,在研究方法上采取多元化的态度。中国心理学史以外在逻辑原则为主导原则,以中国心理学思想为研究对象,形成了系统的研究方法。中国的本土心理学和中国心理学史研究有相同的文化背景和研究价值,这构成了二者契合的前提。中国的本土心理学和中国心理学史可以相互借鉴,共同建构科学的中国心理学。
