As the incomes of affluent and poor families have diverged over the past three decades, so too has the educational performance of their children. But how exactly do the forces of rising inequality affect the educational attainment and life chances of low-income children? In Whither Opportunity? a distinguished team of economists, sociologists, and experts in social and education policy examines the corrosive effects of unequal family resources, disadvantaged neighborhoods, insecure labor markets, and worsening school conditions on K-12 education. This groundbreaking book illuminates the ways rising inequality is undermining one of the most important goals of public education—the ability of schools to provide children with an equal chance at academic and economic success. The most ambitious study of educational inequality to date, Whither Opportunity? analyzes how social and economic conditions surrounding schools affect school performance and children’s educational achievement. The book shows that from earliest childhood, parental investments in children’s learning affect reading, math, and other attainments later in life. Contributor Meredith Phillip finds that between birth and age six, wealthier children will have spent as many as 1,300 more hours than poor children on child enrichment activities such as music lessons, travel, and summer camp. Greg Duncan, George Farkas, and Katherine Magnuson demonstrate that a child from a poor family is two to four times as likely as a child from an affluent family to have classmates with low skills and behavior problems – attributes which have a negative effect on the learning of their fellow students. As a result of such disparities, contributor Sean Reardon finds that the gap between rich and poor children’s math and reading achievement scores is now much larger than it was fifty years ago. And such income-based gaps persist across the school years, as Martha Bailey and Sue Dynarski document in their chapter on the growing income-based gap in college completion. Whither Opportunity? also reveals the profound impact of environmental factors on children’s educational progress and schools’ functioning. Elizabeth Ananat, Anna Gassman-Pines, and Christina Gibson-Davis show that local job losses such as those caused by plant closings can lower the test scores of students with low socioeconomic status, even students whose parents have not lost their jobs. They find that community-wide stress is most likely the culprit. Analyzing the math achievement of elementary school children, Stephen Raudenbush, Marshall Jean, and Emily Art find that students learn less if they attend schools with high student turnover during the school year – a common occurrence in poor schools. And David Kirk and Robert Sampson show that teacher commitment, parental involvement, and student achievement in schools in high-crime neighborhoods all tend to be low. For generations of Americans, public education provided the springboard to upward mobility. This pioneering volume casts a stark light on the ways rising inequality may now be compromising schools’ functioning, and with it the promise of equal opportunity in America.

Based on a study of 256 exemplary community college presidents, this book examines the attributes of outstanding leaders and their ability to orchestrate organizational change. Chapter 1 provides the background for the study, emphasizes the importance of leadership, and identifies attributes common to transformational leaders; that is, leaders who work with their followers so that each raises the other to higher levels of motivation and morality. Chapter 2 summarizes leadership theory and offers a discussion of transformational leadership and its place in a rapidly changing society. After chapter 3 reviews the study methodology, chapters 4 and 5 present findings on the demographic and leadership characteristics of the presidents selected for in-depth study. Chapters 6 through 10 discuss key elements of transformational leadership, including shared vision, teamwork and collaborative decision making, institutional climate and the relationship between the institution and the individuals within it, motivation as a means of achieving followers' acceptance of the shared vision, and personal values, integrity, and commitment to learning. Chapter 11 examines women in community college leadership roles. Finally, chapter 12 presents a summary of the research, a discussion of the problems faced by minority leaders, and a review of study implications. The survey instruments and an eighty-five-item bibliography are appended.

Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
