Taking out student loans to assist with the costs of postsecondary schooling in the US has become the norm in recent decades. The debt burden young adults acquire during the higher education process, however, is increasingly stratified with black young adults holding greater debt burden than whites. Using data from the NLSY 1997 cohort, we examine racial differences in student loan debt acquisition and parental net wealth as a predictor contributing to this growing divide. We have four main results. First, confirming prior research, black young adults have substantially more debt than their white counterparts. Second, we find that this difference is partially explained by differences in wealth, family background, postsecondary educational differences, and family contributions to college. Third, young adults’ net worth explain a portion of the black–white disparity in debt, suggesting that both differences in accumulation of debt and ability to repay debt in young adulthood explain racial disparities in debt. Fourth, the black–white disparity in debt is greatest at the highest levels of parents’ net worth. Our findings show that while social and economic experiences can help explain racial disparities in debt, the situation is more precarious for black youth, who are not protected by their parents’ wealth. This suggests that the increasing costs of higher education and corresponding rise in student loan debt are creating a new form of stratification for recent cohorts of young adults, and that student loan debt may be a new mechanism by which racial economic disparities are inherited across generations.  相似文献

Disparities are pronounced along racial/ethnic lines in the USA. Convention draws our attention to blacks and whites, but increased racial/ethnic diversity in the USA requires shifts in that focus. We contribute to studies of racial/ethnic stratification by interrogating the association between racial/ethnic composition and supermarket location in Houston, Texas. First, we assess the benefits of a new approach to defining the racial/ethnic composition of local areas, an approach that acknowledges an increasingly complex racial/ethnic demography. Second, we contribute to our understanding of emerging racial/ethnic stratification hierarchies by examining the position of the racial/ethnic composition categories relative to one another. Our results suggest a persistent link between racial/ethnic composition and supermarket location, which highlights entrenched black disadvantage coupled with malleable middle positions for Hispanic areas. The associated stratification hierarchy is gradual in nature, yet there is evidence supporting arguments that the USA is moving toward a tri-racial system.  相似文献

In multivariate regression, a graphical diagnostic method of detecting observations that are influential in estimating regression coefficients is introduced. It is based on the principal components and their variances obtained from the covariance matrix of the probability distribution for the change in the estimator of the matrix of unknown regression coefficients due to a single-case deletion. As a result, each deletion statistic obtained in a form of matrix is transformed into a two-dimensional quantity. Its univariate version is also introduced in a little different way. No distributional form is assumed. For illustration, we provide a numerical example in which the graphical method introduced here is seen to be effective in getting information about influential observations.  相似文献

Women with histories of childhood sexual abuse (CSA) were asked to describe what was helpful and unhelpful to them in therapy. From 191 completed postal questionnaires, a subsample of 20 participants was interviewed. This paper focuses on three specific areas of therapy raised by interviewees: (1) Establishing a therapeutic relationship; (2) talking about experiences and effects of CSA; and (3) dealing with errors in therapy. Findings suggest that to avoid making serious therapy errors, therapists (1) need special skills to be aware of the dynamics and effects of CSA and of abuse-focused therapy and to deal with abuse-related material, and (2) need to develop an equal and open therapy relationship that includes ongoing consultation with clients about their experiences of therapy. doi:10.1300/J070v15n04_03.  相似文献

Recognizing the importance of interfirm collaboration and recent advancement of information technology (IT) to enhance joint decision making between firms, this study conceptualizes systems collaboration and strategic collaboration as two essential types of interfirm collaboration. The study then simultaneously examines the multiple roles of systems collaboration and strategic collaboration, and how they directly and indirectly influence a firm's supply chain responsiveness and market performance. Hypotheses are tested on survey data collected from 184 firms. Results suggest that the sequential relationships among IT competency, interfirm collaboration, and supply chain responsiveness have significant market performance implications.  相似文献

This paper considers the problem of Bayesian automatic polynomial wavelet regression (PWR). We propose three different Bayesian methods based on integrated likelihood, conditional empirical Bayes, and reversible jump Markov chain Monte Carlo (MCMC). From the simulation results, we find that the proposed methods are similar to or superior to the existing ones.  相似文献

Although people overwhelmingly believe that liars avoid eye contact, meta-analyses of deception literature have shown a non-significant relationship between gaze and deception. In the present experiment we measured eye movements in an innovative way. We coded the extent to which interviewees deliberately made eye contact with the interviewer. Liars take their credibility less for granted than truth tellers. They therefore may have a greater desire to be convincing and hence more inclined to monitor the interviewer to determine whether they seem to be being believed. We therefore hypothesized that liars would give more appearance of deliberately making eye contact than truth tellers (a relationship which opposes the stereotypical belief that liars look away). A total of 338 passengers at an international airport told the truth or lied about their forthcoming trip. As well as the deliberate eye contact variable, we coded the amount of time the interviewees looked away from the interviewer (e.g., gaze aversion), which is typically examined in deception research. Liars displayed more deliberate eye contact than truth tellers, whereas the amount of gaze aversion did not differ between truth tellers and liars.  相似文献
