A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.
An essential collection of scholarly essays on the anthropology of Africa, offering a thorough introduction to the most important topics in this evolving and diverse field of study The study of the cultures of Africa has been central to the methodological and theoretical development of anthropology as a discipline since the late 19th-century. As the anthropology of Africa has emerged as a distinct field of study, anthropologists working in this tradition have strived to build a disciplinary conversation that recognizes the diversity and complexity of modern and ancient African cultures while acknowledging the effects of historical anthropology on the present and future of the field of study. A Companion to the Anthropology of Africa is a collection of insightful essays covering the key questions and subjects in the contemporary anthropology of Africa with a key focus on addressing the topics that define the contemporary discipline. Written and edited by a team of leading cultural anthropologists, it is an ideal introduction to the most important topics in the field, both those that have consistently been a part of the critical dialogue and those that have emerged as the central questions of the discipline’s future. Beginning with essays on the enduring topics in the study of African cultures, A Companion to the Anthropology of Africa provides a foundation in the contemporary critical approach to subjects of longstanding interest. With these subjects as a groundwork, later essays address decolonization, the postcolonial experience, and questions of modern identity and definition, providing representation of the diverse thinking and scholarship in the modern anthropology of Africa.
Individuals, groups, and societies all experience and resolve conflict. In this handbook, scholars from multiple disciplines offer perspectives on the current state and future challenges in negotiation and conflict resolution. This confluence of research perspectives will identify further synergies and advances in our understanding of conflict resolution.

Current data and trends in morbidity and mortality for the sub-Saharan Region as presented in this new edition reflect the heavy toll that HIV/AIDS has had on health indicators, leading to either a stalling or reversal of the gains made, not just for communicable disorders, but for cancers, as well as mental and neurological disorders.
Recent growth accelerations in Africa are characterized by increasing productivity in agriculture, a declining share of the labor force employed in agriculture and declining productivity in modern sectors such as manufacturing. To shed light on this puzzle, we disaggregate firms in the manufacturing sector by size using two newly created panels of manufacturing firms, one for Tanzania covering 2008-2016 and one for Ethiopia covering 1996-2017. Our analysis reveals a dichotomy between larger firms that exhibit superior productivity performance but do not expand employment much, and small firms that absorb employment but do not experience any productivity growth. We suggest the poor employment performance of large firms is related to use of capital-intensive techniques associated with global trends in technology.
In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.
Wangari Muta Maathai was a scholar-activist known for founding the Green Belt Movement, an environmental campaign that earned her the Nobel Peace Prize. While many studies of Maathai highlight her activism, few examine Maathai as a scholar whose contributions to various disciplines and causes spanned more than three decades. In Radical Utu: Critical Ideas and Ideals of Wangari Muta Maathai, Besi Brillian Muhonja presents the words and works of Maathai as theoretical concepts attesting to her contributions to gender equality, democratic spaces, economic equity and global governance, and indigenous African languages and knowledges. Muhonja’s well-rounded portrait of Maathai’s ideas offers a corrective to the one-dimensional characterization of Maathai typical of other works.
Although the book explores the roles that other factors - such as regional and systemic power relationships, the terms of the settlement itself, and the role of "ripeness" - play in the success or failure of these peace settlements, it concludes that success hinges more on what third parties do and do not do.
