Academic achievement gaps between high- and low-income students born in the 1990s were much larger than between cohorts born two decades earlier. Racial/ethnic achievement gaps declined during the same period. To determine whether these two trends have continued in more recent cohorts, we examine trends in several dimensions of school readiness, including academic achievement, self-control, externalizing behavior, and a measure of students’ approaches to learning, for cohorts born from the early 1990s to the 2000–2010 midperiod.

How common is self-citation in scholarly publication and does the practice vary by gender? Using novel methods and a dataset of 1.5 million research papers in the scholarly database JSTOR published between 1779-2011, we find that nearly 10% of references are self-citations by a paper's authors. We further find that over the years between 1779-2011, men cite their own papers 56% more than women do. In the last two decades of our data, men self-cite 70% more than women. Women are also more than ten percentage points more likely than men to not cite their own previous work at all.

Some contend that the American poor are affluent by international standards, and recent survey evidence finds that Americans have deeply divided views about the conditions faced by the poor in this country. To what extent can poverty in the United States be compared to conditions in the world’s poorest nations? Few analysts have examined this question beyond “instrumental”measures of poverty such as income and consumption that only indirectly capture well­being (Sen, 1999).

Although growth in the U.S. prison population over the past twenty-five years has been widely discussed, few studies examine changes in inequality in imprisonment. We study penal inequality by estimating lifetime risks of imprisonment for black and white men at different levels of education. Combining administrative, survey, and census data, we estimate that among men born between 1965 and 1969, 3 percent of whites and 20 percent of blacks had served time in prison by their early thirties. The risks of incarceration are highly stratified by education.

Legal precedent establishes juvenile offenders as inherently less culpable than adult offenders and thus protects juveniles from the most severe of punishments. But how fragile might these protections be? In the present study, simply bringing to mind a Black (vs. White) juvenile offender led participants to view juveniles in general as significantly more similar to adults in their inherent culpability and to express more support for severe sentencing.
