Black Morocco: A History of Slavery, Race, and Islam chronicles the experiences, identity and achievements of enslaved black people in Morocco from the sixteenth century to the beginning of the twentieth century. Chouki El Hamel argues that we cannot rely solely on Islamic ideology as the key to explain social relations and particularly the history of black slavery in the Muslim world, for this viewpoint yields an inaccurate historical record of the people, institutions and social practices of slavery in Northwest Africa. El Hamel focuses on black Moroccans' collective experience beginning with their enslavement to serve as the loyal army of the Sultan Isma'il. By the time the Sultan died in 1727, they had become a political force, making and unmaking rulers well into the nineteenth century. The emphasis on the political history of the black army is augmented by a close examination of the continuity of black Moroccan identity through the musical and cultural practices of the Gnawa.

The Great Migration and the Formation of Society and Culture in the Seventeenth Century

# data[].attributes.description
Through analyses of the process of migration and settlement and of the symbolic meaning that participants attached to their experiences, this book tells the story of New England's origins as one of dynamism and change. Focusing on the lives of nearly seven-hundred emigrants, the narrative examines such topics as the settlers' motives for leaving England, their experience of the voyage, their patterns of settlement in the New World, and their search for economic security in a new land. The descendants of the founders erected the story of their 'great' migration into early British America's only effective foundation myth - a record of achievement that succeeding generations could never match. Rich in detail and insight, this exploration of New England's founding examines both the lives of ordinary people and the transcendent meanings that those lives ultimately acquired.

The d'Hauteville Case and Legal Experience in Antebellum America

# data[].attributes.description
A Judgment for Solomon tells the story of the d'Hauteville case, a controversial child custody battle fought in 1840. It uses the story of one couple's bitter fight over their son to explore some timebound and timeless features of American legal culture. In a narrative analysis, it recounts how marital woes led Ellen and Gonzalve d'Hauteville into what Alexis de Tocqueville called the 'shadow of the law'. Their multiple legal experiences culminated in an eagerly followed Philadelphia trial that sparked a national debate over the legal rights and duties of mothers and fathers, and husbands and wives. The story of the d'Hauteville case explains why popular trials become 'precedents of legal experience' - mediums for debates about highly contested social issues. It also demonstrates the ability of individual women and men to contribute to legal change by turning to the law to fight for what they want.

Contemporary Religious Change in Latin America

# data[].attributes.description
A massive religious transformation has unfolded over the past forty years in Latin America and the Caribbean. In a region where the Catholic Church could once claim a near monopoly of adherents, religious pluralism has fundamentally altered the social and religious landscape.     Conversion of a Continent brings together twelve original essays that document and explore competing explanations for how and why conversion has occurred. Contributors draw on various insights from social movement theory to religious studies to help outline its impact on national attitudes and activities, gender relations, identity politics, and reverse waves of missions from Latin America aimed at the American immigrant community.      Unlike other studies on religious conversion, this volume pays close attention to who converts, under what circumstances, the meaning of conversion to the individual, and how the change affects converts beliefs and actions. The thematic focus makes this volume important to students and scholars in both religious studies and Latin American studies.

A History of the Eradication of Poliomyelitis

# data[].attributes.description
In 1988, the World Health Organization launched a campaign for the global eradication of polio. Today, this goal is closer than ever. Fewer than 1,300 people were paralyzed from the disease in 2004, down from approximately 350,000 in 1988.

In The Death of a Disease, science writers Bernard Seytre and Mary Shaffer tell the dramatic story of this crippling virus that has evoked terror among parents and struck down healthy children for centuries. Beginning in ancient Egypt, the narrative explores the earliest stages of research, describes the wayward paths taken by a long line of scientists-each of whom made a vital contribution to understanding this enigmatic virus-and traces the development of the Salk and Sabin vaccines. The book also tracks the contemporary polio story, detailing the remaining obstacles as well as the medical, governmental, and international health efforts that are currently being focused on developing countries such as India, Pakistan, Nigeria, and Niger.

At a time when emerging diseases and the threat of bioterrorism are the focus of much media and public attention, this book tells the story of a crippling disease that is on the verge of disappearing. In the face of tremendous odds, the near-eradication of polio offers an inspiring story that is both encouraging and instructive to those at the center of the continued fight against communicable diseases.

Clinical Context for Evidence-Based Practice

# data[].attributes.description
The Evidence-Based Nursing Series is co-published with Sigma Theta Tau International (STTI). The series focuses on implementing evidence-based practice in nursing and midwifery and mirrors the remit of Worldviews on Evidence-Based Nursing, encompassing clinical practice, administration, research and public policy.  Clinical Context for Evidence-Based Practice provides insights into the key contextual issues to be considered in the implementation and assessment of evidence-based practice. Increasingly, implementation research is demonstrating that for evidence to be successfully implemented into practice, the context of practice needs to be considered. Clinical Context for Evidence-Based Practice addresses professional, educational, and organizational contextual issues that impact on the implementation of evidence into practice and the bringing about of practice change. Practical strategies that have been used effectively to overcome these contextual issues in a range of healthcare settings are identified. Specific contextual issues in different care settings are also addressed e.g. acute care, primary health care, peri-operative settings, paediatrics, aged care, mental health, midwifery. Each chapter is written by an internationally known and respected author, with experience of developing or reviewing contextual strategies that have an impact on the implementation and utilisation of research in practice. They explore how gaining a better understanding of context made a difference to the implementation process or outcome and address the potential to transfer different approaches to a range of healthcare settings.  An informative, practical resource for nurses and other health care professionals Explores context-related models and approaches to implementation Informs implementation and enables effective decision making Critically appraises contextual factors across the spectrum of care Explores future directions and implications Includes case examples

The Preferential Option for the Poor beyond Theology

# data[].attributes.description
Since the 1973 publication of Gustavo Gutierrezs groundbreaking work A Theology of Liberation, liberation theology's central premise of the preferential option for the poor has become one of the most important yet controversial theological themes of the twentieth century. As the situation for many of the worlds poor worsens, it becomes ever more important to ensure that the option for the poor remains not only a vibrant theological concept but also a practical framework for living out the gift and challenge of Christian faith. The Preferential Option for the Poor beyond Theology draws on a diverse group of contributors to explore how disciplines as varied as law, economics, politics, the environment, science, liberal arts, film, and education can help us understand putting a commitment to the option for the poor into practice.

The central focus of the book revolves around the question: How can one live a Christian life in a world of destitution? The contributors address the theological concept of the option for the poor as well as the ways it can shape our social, economic, political, educational, and environmental approaches to poverty. Their creative examples serve as an inspiration to all those who are seeking to put their talents at the service of human need and the building of a more just and humane world.

In 2002 the No Child Left Behind Act rocked America's schools with new initiatives for results-based accountability. But years before NCLB was signed, a new movement was already under way by mayors to take control of city schools from school boards and integrate the management of public education with the overall governing of the city. The Education Mayor is a critical look at mayoral control of urban school districts, beginning with Boston's schools in 1992 and examining more than 100 school districts in 40 states.

The authors seek to answer four central questions:
What does school governance look like under mayoral leadership?
How does mayoral control affect school and student performance?
What are the key factors for success or failure of integrated governance?
How does mayoral control effect practical changes in schools and classrooms?

The results of their examination indicate that, although mayoral control of schools may not be appropriate for every district, it can successfully emphasize accountability across the education system, providing more leverage for each school district to strengthen its educational infrastructure and improve student performance. Based on extensive quantitative data as well as case studies, this analytical study provides a balanced look at America's education reform.

As the first multidistrict empirical examination and most comprehensive overall evaluation of mayoral school reform, The Education Mayor is a must-read for academics, policymakers, educational administrators, and civic and political leaders concerned about public education.
